Influence of Axial Clearance of Orbiting Scroll on Working Performance of Scroll Compressor

The working performance of scroll compressor is influenced by the value of orbiting scroll's axial clearance mostly.In order to determine the best value of this clearance,the volume efficiency,power and machinery efficiency are obtained,through experiment by using a kind of structure in which this clearance can be changed,and their variation law is analyzed.At last the best clearance value is obtained.The study results are useful for the design of scroll compressor.
