摘要
大功率风机由工频运行改为变频器调速运行后,在满足系统压力需要的同时,可节约大量的能源。本文介绍了某公司高压排风机变频改造前存在的问题、变频改造方案及改造效果。
After the operation mode of heavy-duty fan was modified from frequency operation into frequency converter operation,the improvement has not only fulfilled the system pressure required but also saved a great deal of energy.This paper introduces the existed problems before frequency converter had been used for the asynchronous motor of high pressure exhaust fan,the modification plan using frequency converter and the modification results in a company.
