小型制冷压缩机中的粉末冶金零件

P/M PARTS IN A SMALL TYPE OF REFRIGERATION COMPRESSOR

本文作者根据我国80年代以来家用电冰箱和空调器生产迅速发展的实际情况,提出解决压缩机供求矛盾的主要途径是小型致冷压缩机的国产化。据此,本文重点介绍了国外小型致冷压缩机粉末冶金零件的开发应用发展情况。同时,就我国当前开发研制小型致冷压缩机粉末冶金零件一事,提出需要特别注意解决的几个问题。

According to the fact that the production of family-expensing refrigerators and air-conditioners has been rapidly developing since eighties,the author has suggested that the main approach of solving the conflict between supplying and demanding compressors is the one of making a small type of refrigeration compressors state-productized. Therefore,this paper has put stress on the introduction for the development survey of exploiting and employing P/M parts in a small type of refrigeration compressors, and meanwhile as for current preparing those P/M parts ,several problems needing special attention have also been put forward.
