Aircraft engine types ✈️

✈️Turbo-Shaft: Used in helicopters and some fixed-wing aircraft, it features a compressor, combustion chamber, and turbine. The turbine drives a power shaft via a free (power) turbine, which powers the rotor or propeller through a gearbox, rather than producing direct thrust. Exhaust gases are expelled separately.

✈️Turbo-Prop: Similar to a turbo-shaft, it powers a propeller via a gearbox. Air is compressed, mixed with fuel, and burned in the combustion chamber. The turbine extracts energy to drive the propeller, with some exhaust thrust. It’s efficient for low-speed, short-range flights.

✈️Turbo-Fan: Common in commercial jets, it has a large fan at the front, high- and low-pressure compressors, a combustion chamber, and turbines. The fan accelerates air around the core (bypass air) for thrust, while the core produces additional thrust via exhaust. It’s efficient for high-speed, long-range flights.

✈️Turbo-Jet: An older design, it compresses air, burns fuel in the combustion chamber, and expels exhaust through a nozzle for thrust. It lacks a bypass fan, making it less efficient but capable of high speeds. Used in early jet fighters and some supersonic aircraft.

✈️Ram-Jet: Operates at high speeds (Mach > 1), using forward motion to compress air in the inlet. Fuel is injected and burned in the combustion chamber, and the exhaust is expelled through a nozzle for thrust. It has no moving parts but only works at high speeds.

✈️Scramjet: A supersonic combustion ramjet, designed for hypersonic speeds (Mach > 5). Air enters at supersonic speeds, is compressed, mixed with fuel, and burned in a combustion chamber, with exhaust expelled for thrust. It’s used in experimental hypersonic vehicles.

✈️Rocket: Uses stored propellants (fuel and oxidizer) in a pressure vessel. Propellants are burned in a combustion chamber, and the high-pressure exhaust is expelled through a nozzle for thrust. It operates in space since it doesn’t rely on atmospheric oxygen.

✈️Gas Turbine: Similar to a turbo-shaft, it’s used for power generation or auxiliary power units. Air is compressed, burned with fuel, and the exhaust drives a power turbine, which can power generators or other systems. Bleed valves and discharge ports manage airflow and pressure.

Each engine type is optimized for specific applications, balancing efficiency, speed, and operational environment.

Top 5 Benefits of Using Rubber Gaskets in Industrial Settings

In the demanding world of industrial manufacturing, efficiency and reliability are non-negotiable. From high-pressure pipelines to sanitary processing systems, one seemingly small component plays a critical role in keeping operations running smoothly: the rubber gasket. At California Rubber, we specialize in precision-engineered rubber gaskets designed for performance, durability, and safety across a wide range of applications.

Rubber gaskets offer significant advantages over metal or fiber alternatives in terms of flexibility, resilience, and resistance to extreme conditions. In this blog, we explore the top five benefits of using rubber gaskets in industrial environments.

1. Superior Sealing Capability

The primary function of any gasket is to create a leak-proof seal between two surfaces, and rubber gaskets excel at this. Thanks to their inherent flexibility and compressibility, rubber gaskets can conform to surface irregularities, ensuring a tight seal even in imperfect or worn flange connections.

This superior sealing capability is particularly vital in high-pressure systems or where liquids and gases must be contained with absolute precision. Components like Sanitary Gaskets used in food and beverage manufacturing rely on high-grade rubber to maintain hygiene and prevent leaks under demanding conditions.

Rubber materials such as EPDM, NBR, and silicone are also excellent at maintaining seal integrity across a wide range of temperatures and pressures, making them ideal for dynamic and static applications alike.

2. Chemical and Temperature Resistance

Industrial environments often expose components to aggressive chemicals and extreme temperatures. Rubber gaskets are available in a variety of formulations that offer excellent resistance to these challenges.

EPDM is commonly used for steam and water applications due to its excellent heat and weather resistance.

Nitrile rubber offers superb resistance to oils, fuels, and other hydrocarbons.

Silicone rubber is ideal for high-temperature sealing up to 230°C (446°F).

This adaptability ensures long-term performance without degradation, reducing the frequency of replacements. It’s particularly valuable in environments such as Cannabis Extraction Parts, where chemical exposure is frequent and operational safety is a top concern.

3. Durability and Longevity

Rubber gaskets are known for their excellent wear and fatigue resistance. When properly installed and maintained, they can provide years of reliable service, even in environments with high levels of vibration, pressure fluctuations, or abrasive materials.

This durability not only lowers the total cost of ownership but also contributes to reduced downtime and maintenance cycles. In sectors like brewing, where production schedules are tight and efficiency is key, using high-performance components such as Brewing Gaskets can significantly improve system reliability.

The use of advanced manufacturing techniques like compression molding and injection molding ensures that rubber gaskets meet precise dimensional tolerances for consistent performance.

4. Noise and Vibration Dampening

In addition to sealing, rubber gaskets offer excellent vibration isolation and noise reduction. Their elastic nature absorbs mechanical energy, dampening vibration between metal parts and reducing wear and fatigue on adjacent components.

This feature is particularly useful in dynamic systems such as pumps, compressors, and HVAC systems. Components like aodd pump parts often integrate rubber seals and diaphragms to ensure quieter operation and longer mechanical life.

By minimizing mechanical noise and vibration, rubber gaskets also contribute to safer and more comfortable working environments in industrial facilities.

5. Versatility Across Applications

Rubber gaskets are incredibly versatile, available in a wide variety of shapes, sizes, and materials to suit almost any industrial requirement. Whether you need a standard flange gasket or a custom-molded seal for a unique configuration, rubber provides a flexible solution.

Their usage spans industries including:

Food and beverage processing

Pharmaceuticals and biotechnology

Oil and gas

Automotive and aerospace

Water treatment and chemical processing

Rubber gaskets can also be tailored to meet regulatory and compliance standards such as FDA, NSF, and USP Class VI, depending on the application.

From standard sealing tasks to highly specialized roles, rubber gaskets can be engineered to solve complex challenges efficiently and economically.

Maintenance Tips for Longer Gasket Life

To get the most out of rubber gaskets, consider these simple but effective maintenance tips:

Perform regular visual inspections for signs of wear, cracking, or hardening.

Ensure proper torque is applied during installation to avoid over-compression.

Store spare gaskets in a cool, dry place away from sunlight and ozone sources.

Replace gaskets at the first sign of leakage to prevent downstream damage.

Proactive care will maximize the life span of your gaskets and ensure uninterrupted system performance.

Why Rubber Gaskets Are a Smart Investment

Rubber gaskets are not only a practical solution for sealing and insulation but also a strategic choice for improving operational efficiency. With the right material and design, they reduce maintenance needs, enhance equipment life, and support safe, clean processing environments.

For manufacturers in regulated industries, choosing the correct gasket material is also key to maintaining product quality and compliance. Investing in high-performance rubber gaskets is ultimately an investment in your operation’s reliability and success.

DUBAI, United Arab Emirates (AP) — Yemen's Houthi rebels likely fired an Iranian-made anti-ship cruise missile at a Norwegian-flagged tanker in the Red Sea in December, an assault that now provides a public, evidence-based link between the ongoing rebel campaign against shipping and Tehran, the U.S. military says.

A report by the U.S. Defense Intelligence Agency released Wednesday linked the attack on the Strinda, which set the vessel ablaze, to Tehran, the Houthi's main backer in Yemen's nearly decadelong war. The findings correspond with those of a Norway-based insurers group that also examined debris found on the Strinda.

It comes as the Houthis continue their monthslong campaign of attacks over the Israel-Hamas war, targeting ships in the Red Sea corridor, disrupting the $1 trillion flow of goods passing through it annually while also sparking the most intense combat the U.S. Navy has seen since World War II.

Iran's mission to the United Nations, responding to questions from The Associated Press, again denied arming the Houthis despite the reports.

“We are aware that (the Houthis) have significantly developed their military capabilities relying on their very own sources,” the mission said. "The prolonged war against them is the primary factor behind the expansion of their military prowess.”

The Strinda was coming from Malaysia and was bound for the Suez Canal and then on to Italy with a cargo of palm oil when it was struck by a missile Dec. 11. The attack sparked a major fire on board that the crew later extinguished without anyone being hurt.

Debris found on board later was analyzed by the U.S. military. The DIA compared the pieces of the engine from the missile found on board to the Iranian Noor anti-ship ballistic cruise missile.

“The Iranian Tolu-4 turbojet engine, used in the Noor (missile), has unique features — including the compressor stage and stator — that are consistent with engine debris recovered from the ... Houthi attack on the M/T Strinda,” the DIA report said. A stator is the stationary portion of an engine.

Those pieces match images of a Tolu-4 engine that Iran displayed at the International Air and Space Show in Russia in 2017, the DIA said. Visually, the engines bore similarities in the photographs.

The Noor was reverse engineered by Iran from the Chinese C-802 anti-ship missile, which Iran purchased from Beijing and began testing in 1996 before transfers stopped over a U.S. pressure campaign. The Iranian version is believed to have a range of up to 170 kilometers (105 miles), with an upgraded version called the Qader having a range up to 300 kilometers (185 miles). The Houthis have a look-alike missile to the Qader called the Al-Mandeb 2 with a similar range.

The Norwegian Shipowners’ Mutual War Risks Insurance Association, known by the acronym DNK, also examined the debris following the Strinda attack. The association assessed it was “highly likely” the vessel had been hit by a C-802 or Noor anti-ship cruise missile.

Before the Houthis swept into Yemen's capital, Sanaa, in 2014, the country did not have an arsenal of C-802 missiles. As the Saudi-led coalition entered Yemen’s conflict on behalf of its exiled government in 2015, the Houthis’ arsenal was increasingly targeted. Soon — and despite Yemen having no indigenous missile manufacturing infrastructure — newer missiles made their way into rebel hands.

Iran long has denied arming the Houthis, likely because of a yearslong United Nations arms embargo on the rebels. However, the U.S. and its allies have seized multiple arms shipments bound for the rebels in Mideast waters. Weapons experts as well have tied Houthi arms seized on the battlefield back to Iran.

While the U.S. has previously accused Iran of supplying the missiles the Houthis use in their attacks at sea, Wednesday's report provided photographic evidence for the first time. The report pointed to a seizure stemming from a Jan. 11 nighttime raid of an Iranian dhow traveling near the coast of Somalia, which saw two Navy SEALs killed. The Navy seized parts related to the Noor anti-ship cruise missile, the report said.

The Houthis have launched seaborne attacks since 2016, when they hit the Emirati vessel SWIFT-1 with a missile as it sailed back and forth in the Red Sea between an Emirati troop base in Eritrea and Yemen. They also tried to attack the USS Mason, an Arleigh Burke-class guided missile destroyer, around the same time.

But the Houthi attacks have rapidly escalated since November over the Israel-Hamas war in the Gaza Strip. The rebels have targeted more than 70 vessels by firing missiles and drones in their campaign that has killed four sailors. They have seized one vessel and sank two in the time since.

The Houthis maintain that their attacks target ships linked to Israel, the United States or Britain as part of the rebels’ support for the militant group Hamas in its war against Israel. However, many of the ships attacked have little or no connection to the war — including some bound for Iran, which backs the Houthis.

“The Houthis probably have used Iran-supplied weapons to conduct more than 100 attacks against land-based targets in Israel, Saudi Arabia, the United Arab Emirates, and Yemen and dozens of attacks targeting ships in the Red Sea and Gulf of Aden,” the DIA report said.

Meanwhile early Friday, the private security firm Ambrey reported that a ship traveling in the southern Red Sea saw what appeared to be a missile splash into the sea and another explode in the air nearby.

The U.S. military's Central Command meanwhile reported that it destroyed five Houthi drone boats and two airborne drones in the Red Sea, while destroying another drone in Houthi-controlled territory.

The Houthis did not immediately acknowledge either incident, though it said U.S.-led airstrikes had targeted the Hodeida region Thursday.

Primary investigation on ram-rotor detonation engine

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, converting chemical energy into thrust efficiently. The concept of harnessing detonation to improve thermodynamic cycle efficiency and enhance the performance of aerospace propulsion systems has been a subject of interest for many years. Since the 1950s, various types of detonation engines have been proposed, including pulse detonation engines, oblique detonation engines, and rotating detonation engines. However, these three types of detonation engines encounter challenges such as poor thrust continuity, high starting Mach numbers, and insufficient performance gains, which limit the widespread application of detonation propulsion technology.

In a recent article featured in the Chinese Journal of Aeronautics, Dr. Haocheng Wen and Prof. Bing Wang from Tsinghua University proposed a new concept for detonative propulsion, called the Ram-Rotor Detonation Engine, which is expected to break through the limitations of the above-mentioned detonation engines.

“The original intention of developing this new engine is to improve the structures of rotating detonation engines,” said Dr. Haocheng Wen, “this concept is also inspired by the ram-rotor compressor.” The ram-rotor detonation engine, abbreviated as RRDE, mainly consists of a rotating rotor with blades, and a stationary casing. The blades on the rotor are distributed in a helical symmetric manner. The combustible mixture undergoes compression, detonation combustion, and expansion within the variable cross-sectional channels between the blades.

The authors performed primary theoretical and numerical investigation on the RRDE. They established a theoretical model to analyze the relationship between the propulsion performance and parameters such as inlet velocity, rotor rim velocity, and equivalence ratio. It is indicated that for the stoichiometric hydrogen/air mixture, the total pressure gain of RRDE can exceed 3. Furthermore, they also conducted numerical simulations on the typical structure of RRDE and obtained the characteristic flow field and propulsion performance of engine. Their simulation results demonstrate that the detonation wave can stabilize and remain stationary within the blades by the given configuration, and can adapt to the variations in parameters such as the equivalence ratio within a certain range. “Our study primarily verifies the performance benefits and operation feasibility of the RRDE.” said Dr. Haocheng Wen.

The authors believe that the RRDE has several advantages, including a simple and compact structure, high efficiency, and the adaptability to a wide-range of flight Mach number. However, they also candidly acknowledge that the realization of the RRDE is confronted with numerous challenges that demand resolution, such as the stabilization mechanism of detonation wave, supersonic boundary layer interference, implementation of high-speed rotor, as well as thermal protection, etc. “Our team is conducting ongoing research on key scientific and engineering issues in RRDE.” said Prof. Bing Wang. They expect the RRDE can provide high-performance propulsion for the supersonic vehicles in the future.

The industry usually employs diesel mobile compressors for water wells and geothermal projects, demanding high exhaust volume, high pressure, and frequent mobility. Depending on the project, the requirements for compressors differ between water and geothermal wells. Since geothermal wells generally have a much deeper drilling depth than water wells, they often adopt multiple parallel machines.

Working conditions: Construction is more common in the colder northern parts of China, with some areas being at a higher altitude.

The typical compressor exhaust volume ranges from 21m3/min to 35m3/min, and the exhaust pressure is between 18kg/cm2 and 35kg/cm2. The drilling diameter ranges from 100mm-400mm.

Air drilling efficiency is significantly higher than the traditional water drilling method and is the inevitable trend for the drilling industry's future development.

Solutions:

Addressing the water well and geothermal industry's needs, our company has specifically developed a high-pressure compressor with an exhaust pressure of 25kg/cm2 and an exhaust volume of 31.5m3/min. With our drilling equipment, we can easily penetrate a 300mm diameter and 200m deep granite geological structure. If two 25kg/cm2, 30m3/min compressors are paired with a 100kg/cm2 booster, we can achieve up to 2800m for geothermal projects, marking a pioneering achievement with our partners.

Given the frequent mobility required by water wells and geothermal projects, we've designed a vehicular high-pressure compressor for easy relocation, eliminating the need for separate power drives, lifting, or transportation, saving users significant time and cost. It's exceptionally convenient for operations within a 100km range.

Our large exhaust volume, dual-stage high-pressure screw compressor, meets the needs of users requiring even higher pressures.

In terms of drilling and geothermal projects, our products have gained widespread recognition in places like Xinjiang, Shandong, Northeast, Henan, and Yunnan.

Maintenance Tips to Keep Your VRF Air Conditioning System Running Smoothly

VRF (Variable Refrigerant Flow) air conditioning systems have become a popular choice for modern buildings due to their energy efficiency, zoning flexibility, and quiet operation. Whether installed in high-end residences, commercial offices, hotels, or healthcare facilities, VRF systems offer intelligent temperature control and long-term cost savings.

However, like all HVAC systems, VRF units require regular maintenance to operate at peak performance. Neglecting service schedules can lead to decreased efficiency, higher energy bills, and costly repairs. Fortunately, with proper care, a VRF system can run smoothly for many years.

Here are some essential maintenance tips to keep your VRF air conditioning system in top shape.

1. Clean or Replace Air Filters Regularly

One of the simplest yet most important maintenance tasks is cleaning or replacing the indoor unit’s air filters. Dust, pollen, and pollutants accumulate on filters over time, obstructing airflow and reducing cooling efficiency.

Frequency: Check filters every 30 to 60 days.

Tip: For dusty environments or commercial spaces, inspect them more frequently.

Dirty filters not only reduce efficiency but also strain the system, causing the compressor to work harder, which can reduce its lifespan.

2. Inspect and Clean Outdoor Units

VRF systems have outdoor condenser units that should be kept clean and unobstructed to ensure proper heat exchange.

Clear debris, leaves, or obstructions from around the unit.

Use a soft brush or low-pressure water to clean the coil fins gently.

Ensure there’s at least 2–3 feet of clearance around the unit for airflow.

Blocked outdoor units can lead to overheating, poor performance, and eventual system failure.

3. Check Refrigerant Levels and Line Integrity

VRF systems depend on precise refrigerant levels for optimal performance. Leaks or low refrigerant levels can disrupt the system’s cooling capacity and energy efficiency.

Schedule professional refrigerant checks annually.

Inspect the refrigerant lines for signs of oil stains, which may indicate a leak.

Monitor for unusual cooling behavior like inconsistent temperatures or high indoor humidity.

Refrigerant leaks can be harmful to both the environment and your system’s components if left unchecked.

4. Ensure Proper Software and Control Calibration

Most modern VRF systems are equipped with advanced controllers and smart zoning capabilities. Over time, these settings may require recalibration.

Check that zone temperatures are accurately set and functioning.

Ensure that scheduling features and energy-saving modes are correctly configured.

Update the firmware/software if new versions are available from the manufacturer.

Well-calibrated controls enhance both comfort and energy savings.

5. Schedule Annual Professional Maintenance

While DIY tasks like cleaning filters are essential, a comprehensive annual maintenance check by a certified HVAC technician is crucial.

A typical service should include:

Indoor and outdoor coil cleaning.

Drain line and pan cleaning to prevent mold or blockages.

Electrical connection inspections.

Compressor and fan motor performance testing.

System diagnostic using manufacturer tools/software.

Preventive maintenance helps identify minor issues before they escalate into costly repairs.

6. Monitor Noise and Vibration Levels

One of the advantages of VRF systems is their quiet operation. If you start to hear buzzing, grinding, or unusual vibrations, it may indicate a mechanical issue.

Inspect fan blades for dirt buildup or misalignment.

Ensure units are securely mounted.

Contact a technician if noises persist—early intervention can prevent serious mechanical failure.

Conclusion

A well-maintained VRF air conditioning system delivers superior comfort, efficient cooling, and long-term reliability. By following these maintenance tips—ranging from simple filter checks to professional servicing—you can keep your system running smoothly and maximize your investment.

Whether your VRF system cools a luxury villa or a multi-floor office complex, regular maintenance ensures it continues to deliver quiet, precise, and energy-efficient climate control year-round.

The Blackbird crew who flew 15,000 miles, in 10 hours 30 minutes non-stop to see how many times the SR-71 could refuel before the liquid nitrogen gave out

J58 engine

SR-71 liquid nitrogen

Five aerial refuellings

SR-71 liquid nitrogen Dewar’s

J58 engine

The SR-71, unofficially known as the “Blackbird,” was a long-range, advanced, strategic reconnaissance aircraft. Throughout its nearly 24-year career, the SR-71 remained the world’s fastest and highest-flying operational aircraft. From 80,000 feet, it could survey 100,000 square miles of Earth’s surface per hour.

The SR-71 aircraft (like its forerunners, the Lockheed A-12 and YF-12A prototype interceptor) is powered by two 34,000 lbf (151,240 N) thrust-class J58 afterburning turbojet engines.

The J58 engine was developed in the late 1950s by Pratt & Whitney Aircraft Division of United Aircraft Corp. to meet a US Navy requirement. It was designed to operate at speeds of Mach 3+ and at altitudes of more than 80,000 feet. The J58 was the first engine designed to operate for extended periods using its afterburner, and it was the first engine to be flight-qualified at Mach 3 for the US Air Force (USAF).

CLICK HERE to see The Aviation Geek Club contributor Linda Sheffield’s T-shirt designs! Linda has a personal relationship with the SR-71 because her father Butch Sheffield flew the Blackbird from test flight in 1965 until 1973. Butch’s Granddaughter’s Lisa Burroughs and Susan Miller are graphic designers. They designed most of the merchandise that is for sale on Threadless. A percentage of the profits go to Flight Test Museum at Edwards Air Force Base. This nonprofit charity is personal to the Sheffield family because they are raising money to house SR-71, #955. This was the first Blackbird that Butch Sheffield flew on Oct. 4, 1965.

SR-71 liquid nitrogen

An engineering marvel, the J58 had a single-shaft rotor design with a novel compressor bleed bypass when in extreme high-speed operation. What made this engine so unique is the six bypass tubes, which directed airflow from the compressor stage directly into the afterburner. This allowed the Blackbird to operate at a much higher fuel efficiency than other afterburning jet engines when in full afterburner (AB).

On Apr. 26, 1971, pilot Lt. Col. Thomas Estes and RSO Lt. Col. Dewain Vick (he and his family were one of my neighbors at Beale AFB) flew SR-71 #968 15,000 miles in 10 hours 30 minutes non-stop on a grueling marathon mission to test the endurance of the J58 engines and the Blackbird airframe, but mostly to see how many times they could refuel before the liquid nitrogen gave out. At Blackbird speeds and temperatures, oxygen becomes explosive and can spontaneously ignite in the tanks and fuel lines. In order to prevent this, all 6 fuel tanks are purged with pure nitrogen before being filled.

The Blackbird also carries 260 liters of liquid nitrogen in 3 dewars [for this flight the SR-71 only had 2 – 106 liter liquid nitrogen dewars. The 3rd 50 liter dewar was added in the mid 1980’s]. This nitrogen expands into its gaseous form as it is pumped into the fuel tanks to top them off as fuel is consumed. Without the nitrogen, the empty fuel tanks would cavitate from the increased pressure when returning to lower altitudes to refuel.*

Five aerial refuellings

Taking off from Beale AFB in California, they flew 2 laps around the continental United States via Missoula, Montana; east to Bismark, ND; southeast to Peoria, IL; east to Columbus, OH; southeast to Cape Hatteras, NC; southwest to Gainsville, FL; south to Tampa, FL; west to San Antonio, TX; northwest to El Paso, TX; west to El Centro, CA; then back to Beale AFB. Once the second lap was complete, they entered the third lap and turned south at Bismark, for Santa Fe, NM; then west to Las Vegas, NV; then finally back to Beale (flight plan via Ron Kloetzli). This 15,000 mile, 10.5 hour flight required five aerial refuellings. After the flight the aircraft was thoroughly examined and found to be none the worse for the experience. The SR-71 remains to this day the only aircraft rated to run in full continuous afterburner.

I interviewed Colonel Shelton about his 13-hour flight during the Yom Kippur war. And he said that after a long flight like this his adrenaline was hyped up so high that he was unable to sleep even though he was exhausted.

To help with his adrenaline being on overdrive he would go for a long walk to settle down.

SR-71 liquid nitrogen Dewar’s

On Sep. 20, 1971, Estes and Vick were awarded the 1972 Harmon International Trophy by President Richard Nixon for their accomplishment. They were also awarded the 1971 Mackay Trophy for the same flight.

*Crew Chief Floyd Jones explains: ‘The SR-71 does have three LN2 Dewar’s, two in nose wheel and the third in the left chine are just outboard of K bay. The LN2 goes from the Dewar’s to coils (heat exchange) in tanks 1 and 3 that turns the Liquid into gasses of nitrogen. The wing tanks are the ones that have the worse leaks.

In screw air compressors, there are no valves or other mechanical forces that can cause obstruction during the compression process. This allows a compressor to operate at high speeds while combining a large flow rate while still being compact than other technologies. The main advantage of using a rotary screw air compressor is that it supplies compressed air continuously with minimal fluctuation in delivery pressure and optimises thermal energy management.

Industrial rotary screw air compressors are instrumental in enhancing productivity, efficiency, and operational cost across various industries by delivering reliable and consistent compressed air for a wide range of applications.

Other advantages of using rotary screw air compressors that will help Africa’s industries grow, include:

Convenient, as they deliver air continuously for the required purposes, and safe, as the chances of having an accident are minimal.

Designed to run tools that generate more power than typical equipment.

Low noise output machine.

Minimum oil-carryovers, as low as 3 ppm in oil lubricated machine.

ELGi’S ROTARY SCREW AIR COMPRESSOR PROFILE

ELGi screw type compressor profile consists of several segments, each with a different shape.

Large positive displacement which increases the pressure by reducing its volume.

Strong female rotor which helps in more tapping of air and reduction of space continuously.

Short sealing line that maintains a seal over the entire contact length which eliminates the need for a sealing strip.

Better clearance distribution.

WHAT IS THE WORKING PRINCIPLE OF ROTARY SCREW AIR COMPRESSOR?

The Rotary Screw air compressor uses a rotary-type positive-displacement mechanism. The screw element consists of two rotors that are similar to a helix, each with a different shape and number of grooves/teeth. Atmospheric air is sucked into this screw element, and as the air progresses along the two interlocking rotors, it gets compressed. The main characteristic of this type of compressor is a male and a female rotor element, which traps the air and compresses it as it passes across the airend.

In an oil-lubricated rotary air compressor, the male rotor is driven by the electric motor or engine, which in turn drives the female rotor and compresses the air due to a reduction in volume.

In an oil-free rotary air compressor the lubricating media is a special coating on the rotors instead of oil which ensures 0 oil carryover to the outlet.

The basic principle of a rotary-type compressor is that both the male and female rotors are spinning in opposite directions. The prime mover turns the rotor of the airend in a rotary screw air compressor. This creates a vacuum resulting in surrounding air being driven into the airends through the air filter. As the rotors turn progressively, the air gets trapped in the spaces between the two screws (rotors).

Air is taken from the atmosphere into the rotary screw compressor through the air intake system. It passes through a filter that helps in removing suspended particles from it. The filtered air goes in the airend, is the heart of the screw type compressor. Here, the air is trapped within the spaces between the two rotors with mesh lobes. . As the rotors turn, they progressively compress the trapped pockets of the air, and the compressed air is discharged at the outlet of the airend.
