摘要： 基于A 企业循环水泵流量高于生产实际需求，从而造成电能大量浪费的现状，对其中两台循环水泵进行变频
改造，另一台维持原状，并对改造前后的用电量进行对比。结果显示，通过变频改造可以明显降低电能消耗量，进而降
低企业生产成本，具有较好的经济效益。

Abstract: Based on the current situation that the flow of circulating water pump in A Enterprise was higher than the actual production
demand, resulting in a large amount of waste of electric energy, two of the circulating water pumps were transformed by
frequency conversion, and the other one remained unchanged, and the power consumption before and after the transformation was
compared. The results show that the power consumption can be significantly reduced by frequency conversion transformation, and
then the production cost of the enterprise can be reduced, which has better economic benefits.

 Key words: circulating water pump; frequency conversion transformation; speed adjustment mode; energy saving
