14. What Are The Factors Involved In Considering The Choice Of Dry Screw Compressor?
Screw compressors are made up of a pair of meshing helical screws that is used to compress the gases. The dry screw compressors are used to have a flow range of 85-170 m/h and the discharge pressure is of 2070-2760 kPa. The dry screw compressor consists of timing gears that is maintained aligned with the rotors. The effectiveness is dependent on the clearances that exist between the helical rotors and between the chambers used for sealing the compression cavities. They are compact and smooth having the limited vibration and require spring suspension as well.
