In the pump industry,much our work involves two extremely simple,yet efficient machines ‐ ‐ the centrifugal pump and the AC induction motor.The centrifugal pump converts mechanical energy into hydraulic (flow,velocity,and pressure) energy and the AC motor converts electrical energy into mechanical energy.Many medium and larger centrifugals offer efficiencies of 75 – 90% and even the smaller ones usually fall into the 50 – 70% range.Large AC motors,on the other hand,can approach an efficiency of 97% and any motor,five hp and above,can be designed to break the 90% barrier.

答案
在泵行业,很多我们的工作涉及两个极其简单,但却能高效的机型---离心泵和交流感应电动机.离心泵可以将机械能转换成液压(流量、速度和压力)能源和交流电动机将电能转化为机械能.很多中小型企业和大型离心型)提供了提高效率的75-90%,甚至较小的通常可以分到50-70%的范围内.
