Universal use and principle of air compressor

With the development of the times, air compressor as a popular use has become more and more common.

The function and use of the air compressor is that the air compressor can provide power by encrypting the air. After compression, air cannot be used as power, machinery and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement in production centers. Air compressors are also used for liquid pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling.

The principle of air compressor

suction process: The screw-type exhaust side suction port must be designed so that the compression chamber can fully inhale. The liquid ring air compressor does not have an intake and exhaust valve group. The intake is only adjusted by the opening and closing of a regulating valve. When the rotor rotates, the tooth groove space of the main and auxiliary rotors is turned to the intake end wall opening., Its space is the smallest. At this time, the tooth groove space of the rotor is the same as the free air in the air inlet, so the air in the tooth groove is all excluded during exhaust.

When the exhaust is finished, the tooth groove is in a high temperature state. When it is turned to the air inlet, the external air is sucked in and flows into the tooth groove of the main and auxiliary rotors along the axial direction. When the water fills the entire tooth groove, the air inlet side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.

Compression process: In the process of gas transportation, the meshing surface gradually moves to the exhaust end, that is, the tooth groove gap between the meshing surface and the exhaust port slowly decreases, and the gas in the tooth groove is gradually compressed and the pressure is strengthened. This is the compression process.

Exhaust process: When the meshing end surface of the air compressor rotor turns to communicate with the casing exhaust, the treated gas starts to be discharged until the meshing surface of the tooth peak and the tooth groove moves to the exhaust end surface. At this time, the area of the tooth groove between the meshing surface of the two rotors and the ventilation port of the casing is zero, thus completing the exhaust method.

As the main gas source of mechanical manufacturing, screw air compressor has been widely used in all walks of life. The "water-lubricated air compressor" produced by Shanghai Granklin Group is an oil-free screw air compressor.
