摘要
本文介绍一种针对水泵电机的软起停方式,它以传统晶闸管软起动的主电路结构为基础,通过转矩闭环控制来调节触发角度,按照水泵系统的特性曲线来控制电机的电磁转矩,使控制电机起停的电磁转矩与泵系统特性曲线相匹配,使水泵能够平稳起停,避免"水锤"现象的发生。
This article introduce a kind of way to start and stop the pump, it based on the traditional thyristor soft start main circuit structure, adjusts the triggering angle through the colsed-loop control, and controls the electrical machinery according to the water pump system characteristic curve the electromagnetism torque, causes to control the electromagnetism torque and the pump system performance curve to start and stop the pump steady, avoid ＂water hammer＂ phenomenon.
