Leakage and friction characteristics at sliding surface of tip seal in scroll compressors.

Type of article: IJR article

Summary

A tip seal is applied to prevent a radial leakage at a tip of scroll wrap in scroll compressors. When the tip seal is pressed hard against a base plate of the scroll, the radial leakage will decrease, while friction at the tip seal will increase. There is a trade-off between the leakage and the friction. It is needed to clarify the relationship between the leakage and the friction at the tip seal to optimize a scroll compressor design. In this study, a test apparatus which could evaluate the leakage and the friction at sliding surface of the tip seal simultaneously was developed. The influence of several parameters, such as upstream pressure, length and width of the tip seal, oil supply rate, rotational speed and oil viscosity, on the seal effect and the friction was examined with the test apparatus, and the influences of these parameters were generalized.
