Abstract

Official abstract text for this publication.

A two-stage medium-pressure screw air compressor includes a primary screw compressor ( 21 ) and a secondary screw compressor ( 22 ) communicating with the gas-liquid separator ( 6 ) via the first gas-liquid inlet ( 61 ). A first oil outlet ( 63 ) is connected to a mid section of a gas-liquid separator ( 6 ). The oil is injected into the lubricating components of the compressor is the first oil outlet ( 63 ), a first filter ( 64 ). A secondary oil-water separator ( 9 ) is connected to the first oil outlet ( 63 ) of the gas-liquid separator ( 6 ), the second oil-water separator ( 6 ) has an upper separating tank ( 91 ) and a lower separating tank. The water and the impurities contained in the lubricating oil can be eliminated at a largest extent, so as to create essential condition thr ensuring the screw compressor to operate continuously, stably and safely and provide high operational reliability, safety and long service life.
