一、引言转速是活塞式压缩机的重要参数之一。转速选取得是否恰当,对压缩机运转的可靠性以及经济性均有不可低估的影响。但是,目前同类型小型压缩机的转速差异很大,转速对机器性能的影响还没有引起人们的足够重视,有关标准也未明确规定各类往复式压缩机的转速,因而,设计者在设计机器时基本上是参考国内外同类型机器而选定。因此,通过试验研究 I. Introduction Speed ​​is one of the important parameters of piston compressor. Appropriate speed selection, the reliability of the compressor operation and economy can not be underestimated. However, the current type of small compressors vary greatly in speed, and the influence of speed on the performance of the machine has not been paid enough attention by people. The standards do not specify the speed of reciprocating compressors. Therefore, when designers design machines When the time is basically the same type of machine at home and abroad and selected. Therefore, through the experimental study
