Internal Structure Of Screw Compressor

The screw compressor is composed of a pair of parallel and meshing cathoin and yang screws, which is the most widely used type of rotary compressor. There are two kinds of single screw and twin screw, and the screw compressor usually refers to the twin screw compressor. Screw compressor can have dry and wet type, the so-called dry type is not sprayed liquid in the working chamber, compressed gas will not be polluted, wet type refers to the working cavity sprayed with lubricating oil or other liquids to cool the compressed gas, improve the seal, and can lubricate the cathogen, male rotor and bearing, to achieve its own transmission, and then through the high-precision filter to remove the oil or other liquid impurities in the compressed air to obtain higher quality compressed gas. Dry type is generally used in occasions with extremely high gas quality requirements and small gas volume requirements, dry screw structure is complex, difficult to maintain, high noise, high cost; Wet type has a wide range of applications, simple structure, easy maintenance, stability and reliability, and is commonly used in aerodynamic engineering.
