RH Oil Free Low Noise Screw Type Compressor

Screw compressors, also known as screw compressors, include screw air compressors and screw process compressors (vinyl chloride compressors, etc.). Screw compressors are positive displacement twin-screw oil-injected compressors, generally box-type skid-mounted structure.

The screw compressor is composed of a pair of parallel, mutually meshing female and male screws, and is the most widely used type of rotary compressors. There are two types of single-screw and twin-screw. Generally speaking, the screw compressor refers to the twin-screw compressor. 

There are two types of screw compressors, dry type and wet type. The so-called dry type means that no liquid is sprayed in the working chamber, and the compressed gas will not be contaminated. The wet type means that lubricating oil or other liquid is sprayed into the working chamber to cool the compressed gas. Improve the seal, and can lubricate the female and male rotors and bearings to realize its own transmission, and then remove the oil or other liquid impurities in the compressed air through a high-precision filter to obtain a higher-quality compressed gas. 

Dry type is generally used in occasions with extremely high gas quality requirements and low gas volume requirements. Dry type screw has complex structure, difficult to maintain, high noise, and high cost; wet type is widely used, simple in structure, easy to maintain, stable and reliable, in aerodynamics Commonly used in engineering
