| 摘 要： | 本文阐述了取水泵变频调节原理及在工程实践。取水泵定速方式调节的主要弊病是：取水泵起停频繁，节流损失大，管道压力大，取水泵单耗相对较高。取水泵应用变频器后能够实现取水量的恒定，减少取水泵的频繁起停，降低单耗，有直接而客观的节能效益。

| Abstract: | The article expounds the variable frequency adjusting theory of water pump and its engineering application. The main disadvantage of constant speed adjusting mode of water pump is that the pump has to be frequently started and stopped. The throttle expense and pipe pressure are high. The unit expense of water pump is relatively high. After the application of inverter on water pump, the water extracting quantity becomes constant and the pump frequent start-stop reduced. Therefore the unit expense decreased. Direct and objective energy-saving benefit will produce while keeping the system circulation for a long time. |
