Opportunities for Innovation with Screw Compressors
نویسنده
چکیده
Screw compressors are at present a widely used means of compressing air, process gas and refrigerants. Computer simulation programs, verified by experimental data and improved by recent advances in mathematical analysis, form a powerful tool for process analysis within these machines and hence for a comprehensive check of innovative suggestions and design optimisation. One consequence of this is that screw rotors lobe profiles have been developed over the past few years which lead to enhanced machine performance. Although efficient operation of screw compressors is mainly dependent on the rotor profile and clearance distribution, other components, such as housing ports, bearings, seals and the lubrication system must be designed to take full advantage of their potential if maximum performance gains are to be achieved. A review of the most recent achievements in application of innovative details into the screw compressor practice is given at the end of this paper.

متن کاملExtending the Operation Range of Dry Screw Compressors by Cooling Their Rotors
Dry screw compressor are limited to maximum pressure ratios of approximately 3:1 due to the high gas temperatures resulting from the compression process, which cause them to deform To attain higher pressure ratios the compressors must be cooled. The main features of heat transfer in screw compressors are reviewed qualitatively and resulting from this, an analytical and experimental study was ca...
