screw compressors working principle | knowledge hub

Working Principle of a Screw Compressor. The oil injected rotary screw compressor is a positive displacement type compressor. A given quantity of air or gas is trapped in a compression chamber and the space that it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge. A rotary screw compressor has a pair

During the unload period, the compressor reaches a low unloaded power consumption (approximately 25% of full load for lubricated screw and vane compressors, and 10 to 20% for reciprocating, oil-free screw, and centrifugal compressors). On oil flooded screw and vane compressors, however, it may take 30 to 60 seconds of unload time for the compressor to reach this lowest unloaded power consumption
