变频器在离心泵中的调速节能原理及应用

Pririciple and example of transducer' s use in centrifugal pump

针对离心泵在油品输转过程中,受设计选型、原料供应、产品销售和操作工况的影响不能满负荷运行的情况,介绍了用变频器,通过对电源频率的改变来调节电机转速,控制离心泵的压力、流量,可以节能的原理,并以应用实例说明了变频调速的特点,以及使泵的实际运行效率提高,收到节能的良好效果。

Transducer is a speed variator, used to change speed of engines. Through change of gear, flow and pressure of pumps are controlled in order to save energy and enhance pump efficiency.
