A STUDY ON WEAR CHARACTERISTICS OF A ROLLING- PISTON-TYPE ROTARY COMPRESSOR

摘要

We have developed a useful means of estimating the wear rate in rolling piston-type rotary compressors. This method can accelerate the estimation of the wear rate of the vane and the piston about 65times as fast as conventional life tests operated continuously. And this method was compared with the data of a component testing, obtained from a pin/block tester in a lubricant/refrigerant mixture. This method was clarified a practical accelerating rate compared with a conventional long-term life test on a benchtester. This paper investigated effects of various lubricants and sliding materials on wear characteristics in a rolling-piston-type rotary compressor using HFCs through that developed method.
