Micro-Oil Screw Air Compressor

The micro-oil screw compressor has the characteristics of reliable operation, few wearing parts, low vibration, low noise, and high efficiency. The screw oil air compressor working principle is to use the power pump or by virtue of the pressure difference generated by itself.

In the compression process, the lubricating oil is continuously injected into the compression chamber and bearings. The design of the oil air compressors for sale has the following characteristics: the injection of lubricant can be formed between the rotor oil film. The secondary rotor can be driven directly by the main rotor without the need for high-precision timing gears, thus making the micro-oiled version more economical than the oil-free version in terms of manufacturing costs. The injection of lubricating oil increases the airtightness. Lubricating oil can reduce the noise generated by high-frequency compression. Lubricating oil can absorb a large amount of heat of compression, so even if the single-stage compression ratio of up to 16 can make the exhaust temperature not too high, the rotor and the casing will not be due to different coefficients of thermal expansion and friction.

Oilless Rotary Screw Air Compressor Maintenance Time And Content

Running for 500 hours: change the screw compressor air filter element just after using a new screw compressor machine.

Running 1000 hours: check the action of compressor intake valve, railing and moving parts, and add grease.

Running 2000 hours or 6 months: whichever comes first check the pipelines, change the lubricant and remove the oil.

3000 hours of operation or one year: Clean intake and exhaust valves.

Advantages of Oil Air Compressors for Sale

Micro-oil screw air compressors have become the new mainstream in the development of the air compressor industry today. Compared with reciprocating compressors of the same power, these micro screw compressor have incomparable advantages and are superior and reliable in performance.

Their small vibration, low noise, high efficiency, and absence of easily damaged parts make these oil air compressors for sale outstanding. The precise fit between the main and auxiliary rotors and between the rotors and the casing reduces gas backflow leakage and improves efficiency.

With only the mutual engagement of the rotors and no reciprocating motion of cylinders, the sources of vibration and noise are reduced. The unique lubrication method brings many advantages.

Micro Screw Compressor Applications

Manufacturing Industry: Micro screw compressors are widely used in various applications within the manufacturing industry, such as pneumatic tools, spray painting, and sandblasting. They are utilized to power pneumatic machinery and equipment, such as drills, grinders, and impact wrenches. Screw type compressors are also employed to provide compressed air for pneumatic conveying systems used to transport materials within manufacturing plants.

Mining Industry: The mining industry requires compressed air for various applications such as drilling, blasting, and ventilation. Screw compressor machines are used to provide compressed air for pneumatic drills used in surface drilling. These micro screw compressors are also employed to supply compressed air for blasting rocks and clearing debris. Oilless screw compressors are also utilized to power ventilation systems, which provide fresh air for miners working underground in mine shafts.

Construction Industry: The construction industry requires compressed air for various applications such as pneumatic tools, sandblasting, and painting. Oil air compressors for sale are used to provide compressed air for pneumatic drills used in drilling holes in concrete and rock. These micro screw compressors are also utilized to supply compressed air for sandblasting equipment, used for removing rust and paint from metal surfaces. Oil less rotary screw air compressors are also employed to power paint sprayers for painting buildings and structures.

Oilless Screw Type Air Compressor Workflow

In the first step, the micro screw compressor draws in the surrounding air through the air filter, so that it enters into the compression main unit.

In the second step, the Yin Yang rotor changes the volume inside the screw type refrigeration compressor through the combined movement. At the same time, the cavity is continuously sprayed with oil to lubricate and cool the screw. This produces a heated oil and gas mixture.

The third step, after the heating and pressurization of the oil and gas mixture through the exhaust check valve into the oil and gas separator tank.

In the fourth step, most of the oil in the main chamber is separated from the compressed air in the oil-air separator, and then cooled and recycled back to the speech machine.

Fifth step, once the air in the oil-air separator reaches the minimum pressure, the minimum pressure valve opens; high temperature compressed air into the after-cooler.

In the sixth step, the temperature of compressed air is cooled down in the after-cooler to get the compressed air you need.
