Screw compressor maintenance organization must find a professional to do, because the technical requirements of this industry is relatively high. In the maintenance of the refrigerant compressor, our semi-hermetic compressors, closed compressor has a wealth of experience. The main business of the central air-conditioning repair screw compressor, piston compressor maintenance, repair centrifugal compressor, scroll compressor maintenance and professional fluoride-resistant, high temperature electrical repair refrigeration equipment maintenance requirements, the technology is mature and experienced. Screw refrigeration compressor works: screw refrigeration compressor and refrigeration compressor piston displacement type compressor belong refrigeration equipment maintenance tender, while the centrifugal refrigeration compressors also belong to Rotary. When the screw refrigeration compressor pressure ratio increased refrigeration equipment maintenance program, volumetric efficiency decreases little closer piston refrigeration compressor screw, screw refrigeration compressor that exhibit the characteristics of a typical reciprocating refrigeration compressors, On the other hand, the operating speed screw refrigeration compressor tall display centrifugal refrigeration compressor characteristics. From this analysis, the screw refrigeration compressors are positive displacement rotary compressor.
