INDUSTRIAL range FINI COMPRESSORS. WORKING PRINCIPLE OF DRY SCREW COMPRESSORS Similar to the reciprocating compressor, the screw compressor is a positive displacement machine. The compression is repeated for each lobe of the rotors. Therefore a 4/6 profile with four lobes on the male rotor has four compression cycles during each rotation of the male rotor. Figure 4 shows the two rotors and the compression chamber from the, This paper will discuss some of the applications and features of screw compressors, basic operating principles and the advantages of the rotary screw over conventional reciprocating compressors for the natural gas compression industry. We will look at the machine itself, as well as the overall compression system and the components required in a screw compressor package. The screw compressors.
