Original Rexroth AA10VO Series Hydraulic Piston Pump

Piston pump is a kind of volume pump. The reciprocating motion of the piston makes the working volume of the pump chamber change periodically, and realizes the inhalation and discharge of liquid. The utility model is composed of a pump cylinder, a piston, an inlet and outlet water valve, an inlet and outlet water pipe, a connecting rod and a transmission device. The piston is driven by power to reciprocate in the pump cylinder.

Working Principle of Original Rexroth AA10VO Series Hydraulic Piston Pump: Piston pump, also known as electric reciprocating pump, can be divided into single cylinder and multi-cylinder from its structure, which is characterized by high lift. It is suitable for transporting oil emulsifiers without solid particles at room temperature. It is used for oil field, coal seam water injection, oil injection and oil recovery, power pump of water-pressure machine of chamber press, hydraulic sand cleaning, ammonia liquid transporting in fertilizer plant, etc. If the overflow component is stainless steel, corrosive liquid can be transported. In addition, high temperature tar, slime, high concentration mortar and high viscosity liquid can also be transported according to different structural materials. The reciprocating motion of the piston pump makes the working volume of the pump chamber change periodically, and realizes the suction and discharge of liquid. The utility model is composed of a pump cylinder, a piston, an inlet and outlet water valve, an inlet and outlet water pipe, a connecting rod and a transmission device. The reciprocating motion of the piston in the pump cylinder depends on the power belt.

When the piston moves upward, the intake valve opens, water enters the pump cylinder, while the water valve on the piston closes, and the water on the upper part of the piston rises upward with the piston; when the piston moves downward, the intake valve closes, and the valve on the piston opens. At the same time, the water pressure in the lower chamber of the pump cylinder rises into the upper chamber and into the outlet pipe, so that the water is continuously discharged from the outlet pipe. Piston pumps are divided into single-acting and double-acting, single-acting, double-acting and multi-cylinder-type, horizontal, vertical and oblique, mobile, manual, pedal and animal-powered.

The flow rate of the piston pump is Q=0.71-6000 m 3/h, and the discharge pressure P2 is less than 39.2 MPa. In most cases, P2 is less than 24.5 MPa. The flow rate of the hydraulic piston pump is determined by the diameter of the pump cylinder, the piston stroke and the number of reciprocating times per minute of the piston. The head depends on the characteristics of the device pipeline, and the flow rate of the same piston pump remains unchanged, while the head can change with the characteristics of the device pipeline.

That is to say, the head is increased, while the flow rate is unchanged, only in the high pressure area, the flow volume is slightly reduced. Piston pump is suitable for high pressure and small flow situations, especially when the flow rate is less than 100 m 3/h and the discharge pressure is greater than 9.8 MPa, it shows its high efficiency and good performance. It can absorb liquids of different media and viscosities. Therefore, it is widely used in petrochemical industry, machinery manufacturing industry, paper making, food processing, pharmaceutical production and so on. Low and medium speed piston pump has low speed and can be operated by manpower and driven by animal power. It is suitable for rural water supply and small-scale irrigation.

When disassembling the piston pump, the pump body must be heated. Otherwise, the hot melt glue can not be disassembled. The main engine can be heated normally first. When disassembling the main engine, half of the work can be completed. (It is better to use hot air gun to produce Sanbai high temperature wind) There are two sealing rings in the pump. If you don’t pull hard, you won’t damage them. Take care when disassembling.

Sumitomo E Series Hydraulic Gear Pump

Hydraulic gear pump is dependent on the pump cylinder and meshing gear formed by the change in working volume and movement to transfer liquid or pressurized rotary pump. Two closed Spaces are composed of two gears, pump body and front and rear covers. When the gear rotates, the volume of the space on the gear side becomes larger from small to large, forming a vacuum. The liquid is sucked in. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. Gear pump outlet pressure is entirely dependent on the size of the pump outlet resistance.

The concept of gear pump is very simple, its most basic form is the same size of two gears in a tight fit housing meshing rotation, the housing of the internal similar to the “8” shape, two gear installed in the inside, the outside diameter of the gear and on both sides with the housing closely. The material from the extruder enters the middle of the two gears at the suction inlet and fills the space. With the rotation of the teeth, it moves along the shell and finally is discharged when the two teeth are engaged.

In technical terms, gear pump is also called positive displacement device, that is, like a cylinder piston, when a tooth into another tooth of the fluid space, because the liquid is incompressible, so the liquid and tooth can not occupy the same space at the same time, so, the liquid is mechanically squeezed out. As the teeth of the continuous mesh, this phenomenon is continuous in the occurrence, so also in the pump outlet to provide a continuous discharge, pump every turn, the amount of discharge is the same. With the continuous rotation of the drive shaft, the pump also uninterrupted discharge of fluid. Pump flow is directly related to the speed of the pump.

In fact, there is a very small amount of fluid loss in the pump, because these fluids are used to lubricate the bearing and gear on both sides, and the pump body is never without clearance with, so can not make the fluid 100% from the outlet discharge, so a small amount of fluid loss is inevitable, which makes the pump operation efficiency can not reach 100%. However, the pump can still run well, for most extruded materials, still can achieve 93% ~ 98% efficiency.

For viscosity or density in the process of fluid change, the pump will not be much affected. If there is a damper, such as a strainer or a restrictor on the discharge side, the pump pushes fluid through them. If the dampers change during operation, that is, if the strainer becomes dirty, clogged, or the back pressure of the limiter increases, the pump will maintain a constant flow until it reaches the mechanical limit of the weakest part of the device (usually with a torque limiter).

Sumitomo E series hydraulic gear pump structure features:

(1) simple structure and low price;

(2) low requirements and wide application;

(3) the end cover and each tooth groove of the gear consists of a lot of fixed sealed working chamber, which can only be used as a quantitative pump.

Gear using the international 90 s advanced level of new technology – double arc sine curve tooth arc. Compared with involute gear, it has the most prominent advantage that there is no relative sliding of tooth profile in the process of gear meshing, so the tooth surface has no wear, running balance, no liquid trapped phenomenon, low noise, long life and high efficiency. This pump gets rid of the shackles of traditional design, and makes the gear pump enter a new field in design, production and use.

The pump is equipped with differential pressure safety valve as overload protection, and the full backflow pressure of the safety valve is 1.5 times of the rated discharge pressure of the pump. It can also be adjusted according to actual needs within the allowable discharge pressure range. However, this safety valve cannot work for a long time and can be installed separately when needed.

Dension Hydraulic Vane Pump T6 Series

The hydraulic vane pump has the advantages of compact structure, small volume (larger displacement per unit volume), smooth operation, uniform output flow, low noise and long service life. It can be made into a directional gear pump or a variable gear pump. The quantitative pump (double or multi-acting) has balanced axial force and long service life. Variable variable mode of the variable pump can be varied, and its structure is simple (such as pressure compensation). Variable displacement pump).

The disadvantage of vane pump is that its oil absorption ability is slightly poor, it is sensitive to oil pollution, and the vane is extended by centrifugal force, so the speed of vane pump can not be too low, and the vane is turning.The contact stress and friction force are very limited when sliding in the sub-groove. It is difficult to increase the pressure and speed of the sub-groove. It is necessary to increase the operating pressure of the vane gear pump.All kinds of measures must be taken to increase the complexity of its structure.

1. Because of the high resistance and leakage of fluid flow, the efficiency is low. If the quantitative vane pump is not properly handled, the leakage will not only pollute the site.It may also cause fire and explosion accidents.

2. Because the working performance is susceptible to temperature changes, it is not suitable to work at very high or very low temperature conditions.

3. Quantitative vane pump components require higher manufacturing accuracy and therefore are more expensive.

4. Due to the leakage of liquid medium and the influence of compressibility, strict transmission ratio can not be obtained.

5. It is not easy to find out the cause when the hydraulic transmission breaks down; the use and maintenance require higher technical level.

Dension Hydraulic Vane Pump T6 Series: compact structure, small size, smooth operation, uniform flow, small fluctuation and noise, long life, efficiency is generally higher than gear pump, price is lower than plunger pump. Small and medium flow vane pumps are often used in throttle control systems. Large flow vane pumps are generally used in non-regulated hydraulic systems to avoid excessive power loss. Vane pumps are commonly used in hydraulic systems of machine tools, hydraulic presses, vehicles, construction machinery and plastic injection machines. Gear pump: simple structure, low price, reliable operation, convenient maintenance, good adaptability to impact load, small inertia of rotating part. Compared with vane pump and plunger pump, the efficiency of bearing is the lowest. It is mainly used in machine tools, construction machinery, mining machinery and agricultural machinery.

Main advantages: (1) Output flow is more uniform than gear pump, running smoothly and noise is less.

(2) The work pressure is higher and the volume efficiency is higher.

(3) Single-acting vane pump (Tokimec Tokyo Meter vane pump) is easy to achieve flow regulation, while double-acting vane pump has a long service life because of the radial hydraulic pressure balanced by the rotor.

(4) Compact structure, small contour size and large flow.

Main shortcomings: (1) The self-priming performance is worse than that of gear pumps, and the requirements for oil absorption conditions are stricter. Its speed range must be in the range of 500-1500r/min.

(2) It is sensitive to oil contamination, the blade is easily bitten by the impurities in oil, and its working reliability is poor.

(3) The structure is more complex, the precision of parts manufacturing is higher, and the price is higher. Blade pump is generally used in medium pressure (6.3 MPa) hydraulic system, mainly used for machine tool control, especially double-acting vane pump (SQP vane pump of Tokyo Meter) because of small flow fluctuation, so it is widely used in precision machine tools.

Dension Hydraulic Vane Pump SDV Series

Hydraulic pumps are key components. Their performance and life largely determine the working ability of the whole hydraulic system. With the development of the times and the progress of technology, the performance of hydraulic pumps has become more and more perfect, and has been widely used in various industrial equipment, walking mechanism, ships and aircraft. Therefore, it is necessary to learn and understand the relevant knowledge of vane pump, especially for those who are engaged in hydraulic related work. Hydraulic pump, as the main power component of modern hydraulic equipment, determines the working ability of the whole hydraulic system. In the hydraulic system, the function of the hydraulic pump is mainly to convert the mechanical energy of the motor and internal combustion engine into the pressure energy of the liquid, to provide pressure oil to the system and to drive the system.

The hydraulic vane pump is one of the earliest practical hydraulic pumps in the history of modern hydraulic technology development. Compared with gear pump and plunger pump, vane pump has the advantages of small size, light weight, uniform flow and low noise. Among all kinds of hydraulic pumps, the weight required for output unit hydraulic power of vane pump is almost the lightest. In addition, the vane pump has simple structure and lower price than plunger pump, so it can compete with gear pump. Quantitative vane pump designed in this subject is a double-acting vane pump, which has been developed and widely used in the industrial field. The double-acting vane pump is generally variable, and the radial force is balanced, so it works better than other pumps. It is widely used in the field of hydraulic system and becomes an indispensable key component in the hydraulic industry.

Classification of vane pumps: The vane pump is divided into double-acting vane pump and single-acting vane pump. Double-acting vane pump can only be used as quantitative pump, single-acting vane pump can be used as variable pump.Dual-acting vane pump is named for its rotor rotating once, blade sliding twice in the slot of the rotor blade, completing oil absorption and pressure twice.The rotor of single-acting vane pump sucks and presses oil once every revolution, so it is called single-acting.

Working Principle of Dension Hydraulic Vane Pump SDV Series: When the rotor of vane pump rotates, under the action of centrifugal force and pressure oil, the tip of the vane is close to the inner surface of the stator. The working volume of the two blades and the inner surface of the rotor and stator consists of small to large oil absorption and then large to small oil drainage. When the blade rotates for one week, two oil absorption and oil drainage are completed.

Cautions for Vane Pump: In addition to preventing dry rotation and overload, inhalation of air and excessive vacuum, the key points of vane pump management should also be noted that Because the rotor blade slot is inclined, the blade has chamfer, the bottom of the blade is connected with the oil discharge chamber, and the throttle slot and suction and discharge outlet on the oil distribution plate are designed according to the established steering. Reversible vane pumps must be specially designed.The assembly of vane pump the correct positioning of oil distribution plate and stator with positioning pin, the blade, rotor and oil distribution plate can not be reversed, and the suction area on the inner surface of the stator is most easily worn out. If necessary, it can be reversed and installed to make the original suction area become the discharge area and continue to use.Disassembly and assembly Pay attention to the cleanliness of the working surface. Oil should be filtered well when working.The blade gap in the slot is too large to increase leakage, and too small to expand freely, which will lead to abnormal work.

Hydraulic pumps are the key components of various hydraulic equipments. Their performance and life largely determine the working ability of the whole hydraulic system. With the development of the times and the progress of technology, the performance of hydraulic pumps has become more and more perfect, and has been widely used in various industrial equipments, walking mechanisms, ships and aircraft. Therefore, it is necessary to learn and understand the relevant knowledge of vane pump, especially for those who are engaged in hydraulic related work. Hydraulic pump, as the main power component of modern hydraulic equipment, determines the working ability of the whole hydraulic system. In the hydraulic system, the function of the hydraulic pump is mainly to convert the mechanical energy of the motor and internal combustion engine into the pressure energy of the liquid, to provide pressure oil to the system and to drive the system.The vane pump is one of the earliest practical hydraulic pumps in the history of modern hydraulic technology development.

Compared with gear pump and plunger pump, hydraulic vane pump has the advantages of small size, light weight, uniform flow and low noise. Among all kinds of hydraulic pumps, the weight required for output unit hydraulic power of vane pump is almost the lightest. In addition, the vane pump has simple structure and lower price than plunger pump, so it can compete with gear pump. Quantitative vane pump designed in this subject is a double-acting vane pump, which has been developed and widely used in the industrial field. The double-acting vane pump is generally variable, and the radial force is balanced, so it works better than other pumps. It is widely used in the field of hydraulic system and becomes an indispensable key component in the hydraulic industry.

Blade pump has many outstanding advantages, so its application is very extensive, such as plastic processing machinery, pressure machinery, machine tools for general industry; construction machinery, construction machinery, agricultural machinery, automobiles, etc. in walking machinery; metallurgical machinery, lifting device, roll adjusting device for iron and steel industry; flood gate and dike device for civil and hydraulic engineering, river bed lifting device, etc. Location and bridge control mechanism; Turbine speed regulating device of power plant, nuclear power plant and so on; deck crane (winch), bow door, bulkhead valve, stern propeller for ships; giant antenna control device for special technology, measuring buoy, lifting and rotating stage; artillery control device for military industry, ship anti-rolling device, aircraft simulation, aircraft landing gear receiving and unloading Both the device and the rudder control device need to be applied to the vane pump.

From low pressure to high pressure: With the progress of hydraulic technology, the demand for pressure of vane pump is higher and higher, and there are many new requirements for vane pump with various performances. With the development of processing technology and technological progress, it is possible to develop high-pressure vane pump. In the past, vane pumps mainly work in 6.3-7.0MP medium and low pressure systems. The development of high performance vane pumps has greatly improved the performance of vane pumps in recent years. The pressure level has generally increased to 16.0-17.5Mp. More and more vane pumps with higher pressure performance have been developed successfully, which greatly enriches the types and performance of vane pumps. 2. High efficiency and low consumption The efficiency of vane pumps has gradually improved. With the improvement of people’s awareness of environmental protection and energy saving, the designers have paid more and more attention to the low consumption of vane pumps, so a number of high efficiency and low power vane pumps have been born.

Working Principle of Original Parker Brand Hydraulic Vane Pump PVS Series: When the rotor of vane pump rotates, under the action of centrifugal force and pressure oil, the tip of the vane is close to the inner surface of the stator. The working volume of the two blades and the inner surface of the rotor and stator consists of small to large oil absorption and then large to small oil drainage. When the blade rotates for one week, two oil absorption and oil drainage are completed.

Classification of vane pumps: The vane pump is divided into double-acting vane pump and single-acting vane pump. Double-acting vane pump can only be used as quantitative pump, single-acting vane pump can be used as variable pump.Dual-acting vane pump is named for its rotor rotating once, blade sliding twice in the slot of the rotor blade, completing oil absorption and pressure twice.The rotor of single-acting vane pump sucks and presses oil once every revolution, so it is called single-acting.

Original Parker Hydraulic Gear Pump PGM Series

Hydraulic gear pump is dependent on the pump cylinder and meshing gear formed by the change in working volume and movement to transfer liquid or pressurized rotary pump. Two closed Spaces are composed of two gears, pump body and front and rear covers. When the gear rotates, the volume of the space on the gear side becomes larger from small to large, forming a vacuum. The liquid is sucked in. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. Gear pump outlet pressure is entirely dependent on the size of the pump outlet resistance.

The concept of gear pump is very simple, its most basic form is the same size of two gears in a tight fit within the shell.Meshing rotation, the inside of this housing is similar to “8” shape, two gears are installed inside, the outside diameter and two sides of the gears are closely matched with the housing. The material from the extruder enters the middle of the two gears at the suction inlet and fills the space. With the rotation of the teeth, it moves along the shell and finally is discharged when the two teeth are engaged.

Original Parker Hydraulic Gear Pump PGM Series:

In technical terms, gear pump is also called positive displacement device, that is, like a cylinder piston, when a tooth into another tooth of the fluid space, because the liquid is incompressible, so the liquid and tooth can not occupy the same space at the same time, so, the liquid is mechanically squeezed out. As the teeth of the continuous mesh, this phenomenon is continuous in the occurrence, so also in the pump outlet to provide a continuous discharge, pump every turn, the amount of discharge is the same. With the continuous rotation of the drive shaft, the pump also uninterrupted discharge of fluid. Pump flow is directly related to the speed of the pump.

In fact, there is a very small amount of fluid loss in the pump, because these fluids are used to lubricate the bearing and gear on both sides, and the pump body is never without clearance with, so can not make the fluid 100% from the outlet discharge, so a small amount of fluid loss is inevitable, which makes the pump operation efficiency can not reach 100%. However, the pump can still run well, for most extruded materials, still can achieve 93% ~ 98% efficiency.

For viscosity or density in the process of fluid change, the pump will not be much affected. If there is a damper, such as a strainer or a restrictor on the discharge side, the pump pushes fluid through them. If the dampers change during operation, that is, if the strainer becomes dirty, clogged, or the back pressure of the limiter increases, the pump will maintain a constant flow until it reaches the mechanical limit of the weakest part of the device (usually with a torque limiter).

There is actually a limit to the speed of a pump, depending on the process fluid. If the oil is being transferred, the pump can rotate at a high speed.It is very important to push the high-viscosity fluid into the two-tooth space on the side of the suction inlet. If this space is not filled, the pump cannot discharge the accurate flow rate. Therefore, PV value (pressure flow rate) is another limiting factor and also a process variable. Due to these limitations, gear pump manufacturers will provide a range of products, that is, different specifications and displacement (output per revolution). These pumps will be combined with specific application processes to optimize system capacity and price.

PEP-II pump gear and shaft as a whole, using the whole body quenching process, can obtain a longer service life. The “D” type bearings incorporate a forced lubrication mechanism to allow the polymer to pass through the bearing surface and return to the inlet side of the pump to ensure effective lubrication of the rotating shaft. This property reduces the possibility of polymer retention and degradation. Precision machining of the pump body can make the “D” type bearing and gear shaft with precision, ensure that the gear shaft is not eccentric, to prevent gear wear. The Parkool sealing structure and teflon lip sealing together constitute a water-cooled seal. This seal does not actually touch the surface of the shaft. It is self-sealing by cooling the polymer to a semi-molten state. Rheoseal seals are also available, which are machined with reverse spiral grooves on the internal surface of the shaft seal to reverse pressure the polymer back to the inlet. To facilitate installation, the manufacturer has designed an annular bolted mounting surface to match the flange mounting of other equipment, which makes the manufacture of cylindrical flanges easier.

The pep-ii gear pump is available with optional heating elements that match the pump specifications to ensure rapid heating and heat control. Unlike the way the pump body is heated, the damage to these components is limited to a single plate, not the entire pump.
