摘要(Abstract):
本文根据容积式压缩机卸荷变工况运行的P-V关系,指出组成容积式压缩机的定容积比式与变容积比式的启动特性截然不同,并通过计算卸荷运行指示功的方法,导出了这两类压缩机卸荷空载启动及卸荷背压启动的启动力矩计算式。
Bassing on the pressure volume relationship of unloading operation of possitive displacement compressors, this article points out that set ratio compressor and charging ratio compresser are totally different in moving characterlstic, and also derived the starting torque formula of unloading nonpressure starting and unloading total pressure starting of these two kinds of compressors, according to the way of calculating the indicated work of unloading movement.
