带串级调速装置的风机系统的使用与改进

Operation and improvement of main blower system with cascade governor

风机系统由离心风机、三相绕线异步电机和晶闸管串级调速装置组成 ,具有结构简单、投资省、操作方便、调速范围宽、自动化程度高等特点 ,适合于在风量及风压波动的冶炼烟气制酸装置中使用。

The blower system consists of centrifugal blower, triple phase asynchronous motor and thyristor cascade governor and has advantages of simple structure, low investment, easy operation, wide regulating arrange and advanced automatic control. It is suited to operate under the condition of fluctuant flow and pressure of off gas in a smelter acid plant. The problems during operation and relative improvement are described.
