Calculating changes of clearances between profiled surfaces of a screw compressor

Noskov A.N.

Abstract
A method has been developed for calculating changes of clearances between screws on the normal line to the screw surface. This method makes it possible to select minimal safe working clearances, thus increasing the work capacity and power efficiency of screw compressors.

Keywords: screw compressor, profiled clearance, steam refrigerator, working substance.
