一、前言比功率是评价压缩机优劣的主要技术经济指标。目前对降低比功率的研究较多地集中在气阀,级间冷却,气流脉动上,而本文的注意力是压缩机活塞环的摩擦损耗。笔者认为高转速双作用压缩机可以使用单根小弹力活塞环来降低比功率。使用单根小弹力环造成泄漏量的 First, the preface Than the power is to evaluate the merits of the compressor technical and economic indicators. At present, the research on reducing the specific power is mainly focused on the valve, the interstage cooling, and the pulsation of the air flow. The attention in this paper is the frictional loss of the compressor piston ring. I believe that high-speed double-acting compressor can use a single small elastic piston ring to reduce specific power. Use a single small elastic ring caused by the amount of leakage
