Multifunctional Screw Compressor Rotors
For many years the authors have been investigating the use of twin screw machines to fulfil both the expansion and compression. One of potential advantages of screw machines over other types of positive displacement machine is their ability to perform both the compression and expansion functions simultaneously, using only one pair of rotors. A further feature is the use of the rotors which seal...
متن کاملApplication of Manufacturing Simulation for Screw Compressor Rotors
This paper shows how simulation of screw rotor profile manufacturing can be used in the design phase to assess profile alternatives. To do this, variations in manufacturing parameters are studied to illustrate how these deviations affect different rotor profile shapes and the resulting rotor pair clearances. INTRODUCTION Clearances between rotors in a twin screw compressor play a key role in de...
متن کاملInspection of Screw Compressor Rotors for the Prediction of Performance, Reliability, and Noise
The relationship between screw compressor problems and characteristics of the rotors themselves continues to interest designers, even though manufacturing accuracy has been vastly improved over the last decade, largely due to the benefits offered by the Co-ordinate Measuring Machine (CMM). Contrary to some predictions, however, pair inspection has not been eliminated, even though the feeler gau...

متن کاملCFD grid generation and analysis of screw compressor with variable geometry rotors
This paper presents development of an algebraic grid generation algorithm applicable to Finite Volume Method for Computational Fluid Dynamics (CFD) calculation of variable pitch twin screw machines. It is based on the principles developed for the uniform pitch rotors with constant cross-section profile. The same algorithm could be also used for rotors with variable profile geometry. Performance...
