摘要
介绍了变频器的工作原理、参数、功能、以及泵的流量、扬程、功率、转速、与电源频率之间的关系,通过应用实例说明变频系统既可控制管道中流体的流量、压力,又可避免设备的损坏。
The working principle, parameters and functions of frequency eonverter, as well as the relation betweenthe flow, lift, power and revolution speed of the pump versus the frequency of the power supply are explained. Appli-cation examples are given out to show that converter system may control the pressure and flow in pipeline, and preventequipment from damage, thus to conserve energy.
