around 如何理解(关于压力控制)? 我来猜猜:the third stage discharge pressure of these compressors is basically controlled by spillback around the third stage of these compressors. in reality the third stage discharge pressure is set to maintain a constant differential pressure between the third stage of the compressor and the interstage separator. 这些压缩机的三级排气压力主要是由压缩机中在三级阶段回流的介质来控制的。实际上,设置三级排放压力是为了维持压缩机内第三级与级间分离器之间的压力差。查看更多
