The Function and Cooling Method of The Engine's Cooling System

The working principle of the cooling system of a diesel generator set is heat transfer. Heat always moves from hot objects to cold objects. There are three ways of heat transfer: conduction, convection, and radiation. Conduction refers to the heat transfer between two solid objects. For example, heat is transferred from the valve stem to the valve guide. Due to both objects being solid, heat is transferred from the hot air rod to the cold valve guide through conduction. For example, heat is transferred from the air duct to the cylinder head through conduction. Heat can be transferred through convection. Convection is the heat transfer that occurs through the circulation of heat in a liquid or gas. Through convection, the heat from the hot cylinder body is transferred to the coolant, and when the hot radiator components transfer heat to the surrounding cold air, convection also occurs.

Radiation is a way of heat transfer. Radiation is the heat transfer that occurs by converting thermal energy into radiant energy. Any hot object emits radiation heat through conduction, and the hotter the object, the greater the radiation energy. When the diesel engine is hot, some of the heat is converted into radiation, approximately 8%. The cooling system removes excess heat from the engine based on these principles. For example, when a person approaches a running engine or other heat source object, although they have not approached it, they can already feel that the engine is hot, which is due to thermal radiation. In order to ensure the optimal operation of the unit engine, a cooling system is necessary. Engine manufacturers typically use two types of cooling systems: hot air (air) cooling systems and liquid (water) cooling systems, corresponding to air-cooled engines and liquid cooled engines.

Function and cooling method of cooling system

When an internal combustion engine is in operation, the combustion of fuel in the cylinder generates a large amount of heat, causing the gas temperature inside the cylinder to reach up to 22002800K (about 19002500C). About one tenth of the heat released by fuel combustion is absorbed by internal combustion engine components. In this way, if the components that come into direct contact with high-temperature gases (such as cylinder liners, cylinder heads, pistons, valves, etc.) are not cooled in a timely manner after being heated, the moving components may expand due to heat and damage the normal clearance, or get stuck due to the failure of lubricating oil. The mechanical strength of each component may also decrease or even be damaged due to high temperature, leading to a decrease in cylinder filling and abnormal combustion. Therefore, in order to ensure the normal operation of internal combustion engines, it is necessary to cool these components that work under high temperature conditions. Of course, the cooling of internal combustion engines must be moderate. If the cooling is excessive, on the one hand, due to excessive heat loss, the amount of heat converted into useful work decreases; On the other hand, the temperature is too low Not conducive to the formation and combustion of combustible mixtures.

The working temperature of an internal combustion engine, whether too high or too low, will reduce its power and economy. The function of the cooling system is to maintain the most suitable working temperature of the internal combustion engine, and to exert its good economy, power, reliability, and durability.

5 Common Mistakes to Avoid When Choosing A Diesel Standby Generator

Before purchasing a backup power generator, you need to consider a number of factors, such as your power requirements and fuel source. A right diesel standby generator can provide you with reliable electricity and bring you peace if mind during power outages. However, many people often make the following 5 common mistakes when buying a backup diesel generator. To make sure you buy a right generator for your home or business, you need to avoid these mistakes.

Overestimate or underestimate power requirements

It’s important to pick a correct size diesel standby generator that can provide the necessary amount of power to run all of the equipment without overloading the generator. If you overestimate or underestimate the power need and select a wrong sized diesel generator set, the generator may be damaged and your business operations may also be affected. Oversizing your generator can lead to inefficient operation and increased fuel consumption, while undersizing may result in power outages during peak demand.

Thus, you should avoid the common pitfalls of oversizing or undersizing your generator. To accurately assess your power requirements, make a list of all the electrical devices and appliances that you need to power during a power outage, identify the wattage for each item and sum up the watts of all the items on your list to determine the total power requirements for your diesel generator. To select the right generator size, you’ll need to know both the required running watts and starting watts. Add the total running watts of all devices you want to run at the same time to your highest single starting watts.

Fail to consider fuel availability

Different types of generators run on different types of fuel, including gas, natural gas, diesel, or propane. Is a diesel standby generator really suitable for you? To select the ideal fuel for your generator, factors such as intended use, availability, efficiency and environmental impact should be considered. Before investing in a generator set, you need to determine the local availability of different fuel types and their costs. In remote areas where natural gas is not available and propane delivery impractical, diesel fuel is the best alternative.

Overlook noise level considerations and potential noise disturbances

Diesel standby generators can be noisy. Not considering the noise level of your generator may cause you a lot of trouble. If you buy a noisy diesel generator for applications such as camping, powering outdoor events, and RVing, you and people around will suffer the loud noise. In addition, many areas, such as residential areas, hospitals and schools, have noise ordinances that may impact generator usage, particularly at night. Thus, the noise level of your generator is a major factor in determining the right model. Look for generators with lower decibel ratings for quieter operation, such as silent diesel gensets.

Buy on price

You get what you pay for. A backup diesel generator offered at a ridiculously low price is most likely low quality. It ends up costing more in the long run. A cheap and low quality generator usually lets you deal with more maintenance issues and less customer service. Dingbo Power recommends that you choose a good quality diesel generator set to provide reliable power and keep you comfortable during future power outages. The initial cost of a high-quality generator is higher, but it is cost-effective in the long run.

Neglect to consider installation and maintenance requirements

When choosing a diesel standby generator, installation requirements and ongoing maintenance should also be considered. Standby generators typically require professional installation. Correct installation from the start could prevent downtime and unnecessary call out charges for a generator that has stopped working. Regular maintenance is also important to keep the optimal performance of generator and make sure it works smoothly when needed. If you overlook the generator maintenance, your generator may fail to supply electricity when the power is out.

Construction of Hole Type Fuel Injector for Diesel Generator Set Part 2

This article continues to introduce the working principle and structure of the hole type fuel injector for diesel generator users.

High pressure fuel enters the annular groove at the upper end of the needle valve body through the oil passage in the filter element and injector body from the inlet pipe joint. This groove is connected to the annular space at the lower part of the needle valve body through two inclined holes. The high-pressure diesel flowing through the lower cavity exerts an upward axial thrust on the conical surface of the needle valve. When this force overcomes the frictional force between the pressure regulating spring and the needle valve body (which is very small), the needle valve moves upward and opens the injection hole [as shown in Figure 5-2 (b)]. Therefore, high-pressure fuel is sprayed into the combustion chamber from the injection hole at the lower end of the needle valve body. The lift of the needle valve is limited by the lower end face of the injector body, which is beneficial for quickly cutting off fuel. When the fuel injection pump stops supplying fuel, due to the sharp drop in oil pressure in the high-pressure fuel pipe, the needle valve quickly closes the injection hole and stops supplying fuel under the action of the pressure regulating spring.

During the operation of the fuel injector, a small amount of fuel will leak out from the gap between the needle valve and the needle valve body. This part of the fuel can lubricate the needle valve and rise along the gap around the tappet, entering the return pipe through the hole on the return pipe bolt 1 and flowing back into the fuel tank. To prevent small debris from blocking the spray hole, a slotted filter element is installed on the high-pressure oil pipe joint.

The fuel injector is fixed in the injector seat hole on the cylinder head with two fixing screws and sealed with a copper cone to prevent air leakage. During installation, the head of the fuel injector should protrude a certain distance from the plane of the cylinder block (specific regulations apply to various machines). For this purpose, shims can be added between the copper cone and the fuel injector, or the copper cone can be replaced to adjust.

The domestically produced 135 series diesel engines all use orifice injectors. Its characteristics are: small nozzle diameter, good atomization quality, but high precision requirements, which brings certain difficulties to small hole processing, and the nozzle is easily blocked by carbon deposits during use.

The pressure regulating spring installed on the upper part of the fuel injector body presses the needle valve tightly against the sealing cone surface of the needle valve body through the tappet, causing the injection hole to close. Only when the oil pressure rises enough to overcome the elastic force of the pressure regulating spring, can the needle valve rise and start fuel injection. The injection pressure at the beginning of injection depends on the elasticity of the pressure regulating spring, which can be adjusted with a pressure regulating screw.

Construction of Hole Type Fuel Injector for Diesel Generator Set Part 1

The fuel of a diesel engine is injected into the cylinder near the end of the compression process. The function of the fuel injector in a diesel generator set is to atomize the fuel into fine particles and distribute them appropriately in the combustion chamber, forming a good combustible mixture. Therefore, the basic requirements for the fuel injector are: a certain injection pressure, a certain range, a certain spray cone angle, good spray, quick fuel stop at the end of fuel injection, and no fuel dripping.

The hole type fuel injector of diesel generator set is mainly used in direct injection diesel engines. Due to the number of spray holes and small aperture, it can spray several spray columns with small cone angles and longer range. The general number of fuel injection holes is 2-8, with a diameter of 0.15-0.50mm. The number and direction of spray holes depend on the requirements of various combustion chambers for atomization quality and the arrangement of injectors in the combustion chamber. For example, the combustion chamber of the 6135G diesel engine is W-shaped, and the formation of the mixture is mainly achieved by directly injecting fuel into the combustion chamber space, so a 4-hole closed injector is used. The nozzle diameter is 0.35mm, the injection angle is 150 degrees, the needle valve opening pressure is 17.5MPa, and the nozzle shape is suitable for the W-shaped combustion chamber.

The main components of fuel injectors are needle valves and needle valve bodies made of high-quality alloy steel, collectively known as needle valve fittings (also known as fuel injector fittings). The cylindrical surface on the upper part of the needle valve is in high-precision sliding fit with the corresponding inner cylindrical surface of the needle valve body, with a clearance of about 0.001-0.0025mm. This gap must be within the specified range. If the clearance is too large, oil leakage may occur, which will reduce the oil pressure and affect the quality of spray; If the gap is too small, the needle valve cannot slide freely. The conical surface of the lower part of the needle valve is fully exposed in the annular oil chamber of the needle valve body. Its function is to withstand the axial thrust caused by oil pressure and make the needle valve rise, so this conical surface is called the pressure bearing conical surface. The conical surface at the lower end of the needle valve is matched with the corresponding inner conical surface on the needle valve body to achieve sealing of the injector cavity, which is called the sealing conical surface. The cylindrical surface at the top and conical surface at the bottom of the needle valve, along with the corresponding mating surface on the needle valve body, are finely ground and then mutually ground to ensure their mating accuracy. Therefore, the selected and ground needle valve components cannot be interchanged.

Diesel Generator Operating Guide: How to Maximize Power Output and Conserve Energy?

In modern society, diesel generators have been widely used in different fields, such as industrial, commercial, medical, communication and emergency relief. They can serve as the main power source or the backup power supply and provide reliable power. Today, Dingbo Power will share several tips on how to use diesel generator sets efficiently, so that you can maximize the power output and conserve energy.

Determine your power requirements

Determining your power needs is an essential precondition for efficient use of diesel generators. You need to figure out the maximum power required, common load rates, continuous operating time, and the need for backup power and so on before buying a diesel generator. Through an accurate power load analysis, you can select a diesel generator set that meet the actual demand, avoiding buying an undersizd generator or oversizd generator.

With the progress of technology, many energy-saving diesel generator sets are now available on the market. These units typically use advanced combustion technology, optimally designed cooling systems and efficient alternators to significantly reduce fuel consumption and emissions while maintaining power output. When choosing a diesel generator, you should focus on some key indicators, such as its thermal efficiency, fuel consumption rate and emission standards.

Install the generator correctly

The installation location of a diesel generator set has an important effect on its operating efficiency and lifespan. You should choose a place with good ventilation, and appropriate temperature and humidity to install the generator set. The installation area should be away from flammable and explosive materials. Meanwhile, considering the impact of noise and vibration caused by diesel generator, corresponding sound insulation and vibration absorption measures should be taken to ensure that the unit does not cause disturbance to the surrounding environment.

During installation, please follow the instructions provided by the manufacturer to ensure that the diesel generator is firmly fixed, the fuel system and cooling system are correctly connected, and the electrical circuit is safe and reliable. In addition, it is also necessary to configure the necessary fire protection facilities to deal with the possible fire risks.

Maintain and service your diesel generator regularly

Regular maintenance is the key to keep diesel generators running efficiently. This mainly include regular inspections, cleanliness, fuel quality, oil changes, battery maintenance, load testing, and professional servicing. You should periodically check the status of consumable parts such as oil, coolant and fuel filters, and timely replace any damaged or aged parts according to the manufacturer’s instructions. Clean the radiator and air filter regularly to keep the generator heat dissipation and air intake smooth. Check and adjust parameters like valve clearance and injection pressure regularly to ensure that the engine is in the best working condition.

Avoid overloading your diesel generator

Generally, diesel generators will be most efficient at their rated load. However, diesel generators running at full load for a long time can lead to some issues such as excessive wear and generator failure. Thus, for best performance and longevity, it's generally recommended to operate diesel generators within their optimal load range rather than at maximum capacity. In actual use, the output power of the your diesel generator should be adjusted reasonably according to the load demand. If necessary, you can use multiple generators in parallel operation and adjust the number of operating units according to load changes to achieve balanced load distribution.

Today, Dingbo Power diesel generator sets are equipped with intelligent control systems, which can monitor the unit's operating status, load conditions, fuel consumption and other key parameters in real time, and automatically adjust the generator's operating parameters according to the preset logic to achieve the optimal power output and energy saving effect.

Use high-quality diesel fuel

Fuel quality directly affects the combustion efficiency and emission performance of diesel generator sets. Using high quality, low sulfur diesel fuel can reduce fuel consumption, reduce carbon accumulation and harmful emissions. Thus, you should use the high quality fuel from reputable sources.

In addition, diesel generator sets will produce a lot of waste heat during operation. Through the implementation of waste heat recovery technology, this waste heat can be used for heating, hot water supply or preheating air intake purposes. This not only improves energy efficiency, but also reduces energy consumption and emissions.

In short, to maximize the power output and conserve energy of your diesel generator set, you need to choose right size generator, install the generator correctly, maintain the generator regularly, avoid overloading and use high-quality fuel. If you are looking for a reliable generator set or having any questions, concerns regarding diesel generators, feel free to contact us today.

Diesel Generator Set Mechanical Blade Oil Transfer Pump Part 2

This article continues to introduce the structure and working principle of mechanical blade type oil transfer pumps and plunger type oil transfer pumps for diesel generator sets.

The fuel consumption of diesel engines varies under different operating conditions. When the load is high, the fuel consumption is high, causing the pressure at the outlet of the fuel pump to decrease. At this time, the plunger is pushed by the plunger spring, increasing the stroke of the plunger and increasing the pump oil volume. On the contrary, as the load on the diesel engine decreases, the fuel consumption decreases, the pressure at the outlet of the fuel transfer pump increases, the plunger stroke decreases, and the pump fuel volume decreases accordingly.

The oil drain hole is used to remove fuel from the gap between the push rod and the pump body, preventing fuel from flowing along the push rod. Insert the tappet into the cam chamber to dilute the lubricating oil in the cam chamber.

The fuel pump is also equipped with a manual fuel pump to remove air from the fuel system. When in use, the handle can be pulled up and down. When the handle is raised, the plunger of the hand oil pump moves upward, and the pressure below the plunger decreases. Fuel enters the fuel valve from the inlet and flows into the upper part of the fuel transfer pump plunger through the oil passage. When the handle is pressed down, the inlet valve closes. The oil pressure above the fuel pump increases, and the check valve is pushed open to pressure the fuel out from the outlet.

The fuel pump is a single acting piston type, installed on the side of the fuel injection spring and driven by an eccentric wheel on the fuel injection pump shaft. Its function is to suck fuel from the fuel tank and supply sufficient fuel to the fuel injection pump at a certain pressure. Before starting the diesel engine, the hand pump on the fuel pump is used to pump oil and remove air from the oil circuit. It can smoothly suck up fuel within 1 meter below the center of the fuel pump within 0.5 minutes. After pumping, the handle nut must be tightened.

The 46 cylinder B series and B series reinforced fuel injection pumps use roller type fuel transfer pumps, while the 12 cylinder B series fuel injection pump is equipped with two roller type fuel transfer pumps with inlet and outlet pipe joints on the left side and a separate hand pump installed at the front end of the diesel engine body.

The working principle of the fuel transfer pump: When the roller and top rod of the fuel transfer pump are at the lowest position of the eccentric wheel of the fuel injection pump, the piston is pushed upward by the action of the spring, and the fuel in the upper chamber of the piston is expelled. At this point, the one-way valve on the oil outlet side closes, and fuel is sent to the fuel filter, creating a space in the lower chamber of the piston The one-way valve of the fuel inlet is opened, sucking in fuel. The eccentric wheel continues to rotate, and the movable chamber begins to move downwards until the roller and top rod come into contact with the highest point of the eccentric wheel. The fuel is squeezed open and enters the upper cavity of the piston through the one-way valve on the outlet side. This cycle continues, sucking in and discharging the fuel. When the positive force of the oil outlet pipeline increases to the point where the oil pressure at both ends of the piston is equal, the piston no longer moves with the top rod to maintain balance, and the oil pump stops working.

Diesel Generator Set Mechanical Blade Oil Transfer Pump Part 1

The function of the fuel pump is to increase the pressure of the oil in the fuel tank to overcome the resistance of the oil passing through the filter, and to continuously deliver diesel with a certain pressure and flow rate to the fuel injection pump. There are many structures of oil pumps, commonly including cycloidal rotor type, mechanical blade type, and plunger type. Dingbo Electric will introduce the structure and working principle of mechanical blade type oil transfer pumps and plunger type oil transfer pumps.

(1) Mechanical blade oil pump. The rotating shaft on the oil pump is not concentric with the inner hole of the eccentric steel cylinder. There are four straight grooves on the rotating cylinder, which are equipped with blades to divide the interior of the eccentric cylinder into three spaces of different volumes, A, B, and C. When the rotating drum rotates, the spatial volume of the three parts mentioned above changes accordingly, with part A increasing and part C decreasing. When the volume increases, a vacuum degree is generated, and fuel is sucked in from the inlet. When the volume decreases, the fuel is squeezed and sent out from the outlet. The fuel supply of the fuel pump is greater than the demand of the diesel engine, so the pressure at the outlet continues to rise. When the pressure rises to a certain level, overcome the pressure of the pressure regulating valve spring, open the pressure regulating valve, and the fuel flows back to the inlet from the pressure regulating valve, keeping the pressure of the fuel delivery pump within a certain range. When in use, the oil supply pressure of the fuel pump can be adjusted by adjusting the pressure screw.

Before starting the diesel engine, the fuel relies on the pressure generated by the height difference of the fuel tank level, overcomes the elastic force of the throttle valve spring, opens the throttle valve, and the fuel enters the fuel system through the small hole on the pressure reducing valve, enters the outlet, and is sent to the fuel system.

(2) The plunger type fuel transfer pump for diesel engines consists of a pump body, plunger, check valve, inlet valve, and hand pressure pump. The 4135 diesel engine fuel transfer pump is basically the same as the 4125 diesel engine fuel transfer pump. A plunger type fuel pump is essentially a combination of a piston and two one-way valves to ensure fuel supply. The fuel supply power can be manual or mechanically driven. Due to the mechanical driving force acting on the roller, it is sometimes also called a roller type fuel pump.

Classification of Electric Fuel Pumps for Electronic Fuel Injection Engines

The electric fuel pump is the "heart" of the fuel supply system in electronic fuel injection engines. The electric fuel pump is a device that continuously draws fuel out of the tank and provides the fuel system with a specified pressure and flow rate. Based on the function of the electric fuel pump, it is known that the performance of the electric fuel pump will directly affect the working performance of the engine.

Electric fuel pump: Electric fuel pumps do have some advantages compared to mechanical ones. After being powered on, the electric fuel pump can operate independently. After turning on the switch, they can pump fuel: mechanical fuel pumps require the diesel engine to start or run before delivering fuel. Another advantage is that the installation position of the electric fuel pump is further away from the engine, so that the heat generated by the engine will not cause the oil pump to produce steam, thus reducing the risk of air resistance. Electric fuel pumps can better cooperate with cars equipped with computer control systems. In addition, electric fuel pumps consume less frictional power. Electric fuel pumps can also generate higher pressure than mechanical fuel pumps: depending on the engine and manufacturer, the average pump pressure is 15-60 psu.

The following types of electric fuel pumps are commonly used: bellows type and impeller blade type.

The displayed circuit controls the electric fuel pump: the current is output from the battery and then flows to the melting line (in the middle of the figure). The fusible link is connected to the fuel pump relay. When the ignition switch is turned on, the coil inside the ECC power relay is energized, causing the ECC power relay switch to close. When the power relay switch is closed, the fuel pump relay coil will continue to be energized. Once powered on, the pump relay switch will close, and then the current will pass through a normally closed delay switch. Subsequently, the current flows to the electric fuel pump, causing the pump motor to operate.

The delay switch is a safety device that will disconnect the circuit in case of accidental impact or accident to the engine. This prevents the fuel pump from continuing to deliver or splashing fuel in the event of a collision.

Bellows type electric fuel pump. A metal bellows is used instead of a diaphragm in the fuel flow of corrugated fuel from the fuel tank to the fuel tank in the carburetor tube type electric fuel pump. Stretching or compressing corrugated pipes can generate suction and pressure. The corrugated tube electric fuel pump shown in Figure 4-11 uses electromagnetic coils to raise or lower the corrugated tube. When current passes through the electromagnetic coil, the armature is attracted to move downwards, causing the metal bellows to elongate and the vacuum to suck in fuel. When the armature reaches its lowest point, the electromagnetic coil is grounded, the current is disconnected, and then the return spring pushes the bellows upward, thereby generating pressure that forces fuel to flow out of the fuel pump and into the carburetor.

What Should be Considered When Choosing Diesel Generators for Livestock Farms?

In the field of modern agriculture, especially in large-scale farming, the stability of power supply is the cornerstone to ensure the smooth operation of production. For farms, whether it is poultry farming, aquaculture or livestock farming, they may face serious economic losses and the animals’ life safety may be at risk when there is a power failure. Therefore, a consensus among many farmers is investing in one or more diesel generators as the backup power supply. How to choose the right diesel generators for livestock farms? Here are several key factors that you need to consider.

Power requirements

Before buying a diesel generator, the first step is to determine how much power you actually need. Both generators and the appliances in your livestock farm use watts (or kilowatts for 1,000 watts) to denote how much electricity they make or use. Assess the power required for daily operations and the likely increase in power demand in the future. Consider the power consumption of lighting, ventilation, heating, feed processing, water pumps, sewage treatment and other equipment. Choose and list essential devices that you want to be able to power concurrently during power outages. Find the running watts of each device listed, add them and record that number. Find the starting watts of each device listed and add the highest starting watts to the total running watts. This will give you the minimum starting watts of a generator to fit your needs. For large farms, emergency equipment that may need to be used in extreme weather or emergencies should also be considered.

Generator size

After determining power requirements, it’s important to select a diesel generator with enough power to power up the essential circuits and keep your livestock farm running smoothly. If the generator is too small, it won't be able to provide enough power to power your livestock farm’s essential appliances and systems. On the other hand, if the generator is too large, you’ll end up wasting fuel and increasing the operating costs. Generally, It is recommended to add a power margin of 10%-20% to cope with future power demand growth or additional power requirements in unexpected situations.

Brand

There are many brands of diesel generator sets on the market, and the quality is uneven. Choosing products with well-known brands, mature technology and good market reputation not only ensures the reliability of equipment, but also reduces the costs of maintenance and repair in the future. Reputable brand generators often have higher fuel efficiency, lower emissions and longer lifespan. Moreover, they usually have an excellent after-sales service network, which can respond in time and solve the problems encountered in the use of equipment.

Fuel efficiency

Fuel efficiency is one of the important indexes to measure the performance of a diesel generator set. Efficient diesel generator sets can reduce fuel consumption and thus reduce the operating costs. In addition, consider the availability and price stability of diesel fuel. In some remote areas, the supply of diesel may be limited. So it is particularly important to choose a generator set that can adapt to local fuel conditions.

Noise level

Select a diesel generator set with low noise and low emissions that meet environmental protection requirements to ensure the production environment of the farm.

Factors to Consider When Choosing Construction Industry Diesel Generators

In the modern construction industry, the stability and reliability of the power supply is one of the key factors to ensure the construction progress and quality. As a commonly used backup power supply, diesel generators can provide stable electricity in the case of mains interruption or instability. However, when buying diesel generators for construction industry, you need to consider many factors to ensure that the equipment can meet the actual needs and your budget.

Power requirements

Before choosing a diesel generator, you should assess the power needs of the construction site. Consider power requirements of equipment that need to operate continuously, such as lighting, office equipment and security monitoring system, and equipment used intermittently, such as mixers, cranes, welders and cutters. The total power requirements of these devices are an important basis for selecting generator sets.

Size of construction sites

Construction site size is also one of the key factors affecting electricity demand. In general, the larger the site, the more power is required.

Small construction sites: This type of construction sites usually carries out simple maintenance work, small road construction or unit housing construction. The power required is relatively small, generally under 30kW. For such construction sites, a small diesel generator set like a 10-30kW model can meet the basic power needs.

Medium construction sites: Medium construction sites are usually for medium road construction, multi-storey residential construction or commercial building construction. The power required is between 30-200kW. For such construction sites, a medium-sized diesel generator ranging from 50-200kW can ensure the normal operation of construction equipment.

Large construction sites: Large construction sites usually carry out large projects such as high-rise buildings, large commercial complexes or road construction. The power required is large, generally more than 200kW, and may be even thousands of kilowatts. For this type of construction sites, it is necessary to select multiple high-power diesel generator sets in parallel to meet the electricity demand during peak hours.

Generator capacity

It’s important to choose a diesel generator with enough power to meet the power requirements of your construction site. When selecting a diesel genset, avoid confusing power units and  ignoring peak demand. KVA is used to represent apparent power and KW is used to represent the real power of an electrical system. In a 100% efficient system kW = kVA. However, electrical systems are rarely ever 100% efficient. Generators usually have a power factor of 0.8. The formula for converting kVA into kW is: Apparent power (kVA) x power factor (pf) = actual power (kW). When selecting a diesel generator, remember to convert KVA to KW to ensure the actual power meets the demand.

Prime Power is the main (prime) source of power on the site, whereas Standby Power (emergency power) is to be used when the main source of power fails. When selecting a generator, consider your actual needs and choose a prime powered generator or a standby generator. In addition, consider electrical load types, starting current and generator power capacity.

Generator Working environment

Generally, the working environment of diesel generator sets for construction sites is harsh, so the impact of environmental factors on generator performance should be taken into special consideration when selecting a generator.

High temperatures: When diesel generators operate in a high temperature environment, the power output will decrease. High temperatures affect the cooling effect of the engine, causing the engine to overheat, which reduces power. Therefore, if you look for a diesel generator that needs to work in high temperature environments, choose a model with forced cooling systems to ensure that the engine can dissipate heat normally.

High-humidity environment: The high humidity environment can cause the internal humidity of the generator set easily, which affects the normal operation of the equipment. Therefore, you should choose a model with waterproof and moisture-proof design to ensure that the equipment can operate stably in a high humidity environment.

High-altitude environment: Altitude is also an important factor affecting the performance of diesel generator sets. As the altitude increases, the air density gradually decreases, which affects the combustion efficiency of the engine. Therefore, in high altitude areas, you should choose models that can adapt to low air density to ensure that the engine can burn and operate normally.

In summary

Choosing the right diesel generators for the construction industry is not an easy task. You need to consider factors such as power needs, construction site size, power capacity, working environments, brand, after-sales service, portability, etc. If you are looking for a diesel generator for your construction site but unsure which one can best fit your needs, contact us today.

Detailed Understanding of Generator Set Protection Parameters

With the development of technology, more and more mechanical equipment will have protective measures. The use of any mechanical equipment is based on safety, and dangerous things will have protective and preventive measures, including diesel generator sets. It is necessary to install protective devices for generator sets that have been operating for a long time and generate mechanical and electrical energy during the operation process.

The four protections of diesel generator sets include: low oil pressure protection, high water temperature protection, overcurrent protection, and overload protection.

When the oil pressure in the generator is low or reaches the warning level, the oil pressure protection system will start working, and the generator set will also issue a low oil pressure alarm and shut down; When the engine fuel supply system malfunctions, the overspeed protection system of the diesel engine starts working, immediately pulling the fuel cut-off valve to shut down the engine.

When the water temperature is high, when the water tank temperature of the generator set reaches 98 degrees or above, the control module of the generator will detect the high water temperature warning and stop for protection;

When the user's load exceeds the rated current of the generator set during overcurrent, the temperature system will start working and the generator set will also issue a shutdown alarm;

When the user's load exceeds the rated power of the generator during overload, the generator will also trigger an alarm and shut down.

In addition, there are many other protective parameters for the generator set, such as low voltage, short circuit, etc., which can be customized according to different customer needs. Advanced diesel generators will also have Chinese fault records to remind mechanics to check the cause of the fault, troubleshoot the generator, and ensure the normal operation of the unit. Main technical parameters of diesel generator set: 3-1000kw, altitude of diesel generator: 0-2000m, relative temperature: ≤ 95%, ambient temperature: -10 ℃ -40 ℃, power supply voltage: 12V/24V, contact output current: 25A, overspeed protection: ≤ 45Hz-65Hz (adjustable) low oil pressure: 0.02MP oil temperature: ≤ 95 ℃ -100 ℃ water temperature: ≤ 95 ℃ -98 ℃.

Attention: Setting protection parameters for diesel generator sets must be done by professional generator set technicians. Non professional operators are prone to setting incorrect parameters, which can lead to diesel generator set failures and reduced service life.

The Relationship Between Diesel Engine Parameters

The three most commonly encountered data when understanding engine parameters are power, torque, and speed. You may have seen these terms and parameters in the manual, but you are not very familiar with their meanings. Today, Guangxi Dingbo Electric Power will discuss the relationship between these three factors with everyone. After understanding them, we can analyze the performance of the engine more comprehensively.

Firstly, Dingbo Power will introduce the concepts of these three, Engine Power unit: hp or kW; Engine Speed Unit: rpm； Torque unit: N·m； Power=n x torque x speed. What do power and torque represent? Why are diesel generators with higher engine power and torque more expensive? What is the relationship between power, speed, and torque? Why does a powerful engine depend on its power and torque? These four questions will be discussed and answered one by one below.

Torque is the force exerted by the piston during one cycle of an internal combustion engine to rotate the engine. There are generally two units of torque, the first being Newton meters; The second type is pound feet. In China, we generally use Newton meters (N · m) more frequently. How should Newton meters be understood? For example, if an engine bursts 200 Newton meters, it is equivalent to applying about 20 kilograms of weight on one end of a one meter lever.

RPM is the number of times the engine rotates in one minute, but there is a two-fold relationship between RPM and cycle. Because the widely used four stroke engine completes one power cycle every two revolutions. That is to say, the engine speed is at 8000 revolutions per minute, which is equivalent to only 4000 power cycles.

The physical definition of power is the amount of work done per unit time. Therefore, power is a physical quantity that describes the speed at which work is done. It can be understood as the energy generated by the engine per unit time. The greater the engine power, the faster the work is done, and the more energy is generated in the same amount of time. Normally, the higher the power of the engine, the higher its maximum speed.

The speed of a diesel engine is much lower than that of a gasoline engine, so under the same displacement, the power of a gasoline engine is higher than that of a diesel engine, but the torque of a diesel engine is higher than that of a gasoline engine. The main reason is that the combustion characteristics of fuels are different. Diesel has a slower combustion speed compared to gasoline, and it takes longer to release energy, resulting in a slower work rate and lower power output. Therefore, diesel engines generally adopt designs with small cylinder diameters and long strokes.

There is a proportional relationship between power, speed, and torque, where power=n x torque x speed (n is a constant). It is not difficult to understand why when we usually see the engine power curve, the torque will suddenly decrease when it reaches its peak, while the speed continues to increase the power and will continue to increase.

For example, the Shangchai E-series engine

Adopting turbocharging technology to increase intercooling and tap into the maximum power of the engine

The power coverage range is 360-460 horsepower, and the maximum torque can reach 2210 Newton meters

Maximum torque engine speed 1100-1400 revolutions per minute

Maximum power reserve coefficient 0.3
