On the cut-off angle for the wraps of scroll compressors An analytical approach
Annotation
The article analyzes different approaches to the modelling of scroll compressor central part. They are compared in terms of different operation principles used for scroll machines. The schemes of spiral cut-off are analyzed. The concept minimal critical angle for spiral cut-off is introduced and substantiated. The technique of the angle estimation, based on the equations for intrados of scroll machine working tool, is suggested. The relevance of correct estimation for the lower boundary of the cut-off angle for wraps in scroll machines designing is emphasized. The technique described is suggested for the purpose.
