摘  要：本文首先对液力耦合器进行了能耗分析，采用变频器对液力耦合器调速设备进行节能改造时，其节电率就等于它们的效率之差，但是在改造时，拆除还是保留液耦对于节电率是有很大差别的，本文详细分析了它们之间的差别。 关键词：变频器；液力耦合器；节电率 Abstract: This article first hydraulic coupling energy analysis carried out, when the inverter is used for hydraulic coupling speed equipment for energy saving, the saving rate is equal to the difference between their efficiency, but at the time of[登陆后可查看全文]
