Everyone is welcome to participate in the discussions. ----------------------------------------------------------- Screw compressors: How do the male and female rotors compress gas by \"chewing\" it? Two screw-shaped rotors, one with protruding teeth and the other with grooves, rotate while interlocking with each other – thus the gas is compressed bit by bit. Unlike reciprocating compressors that use pistons for propulsion, or centrifugal compressors that rely on impellers for rotation, screw compressors represent the third most widely used type in the process industry. Screw compressors account for about 40% of the market share in industrial compressors, and they can be found everywhere, from gas used in chemical instrumentation to natural gas transmission and distribution. 5 diagrams clearly illustrate the working principle of the positive and negative rotors, the fuel-injection and oil-free pathways, inter-stage cooling, and typical failure modes.
