轴流式风机常见故障原因分析及处理方法

Reasons analysis and treatment method on the common faults of axial flow fan

华电包头发电有限公司#1、#2锅炉装配的轴流式一次风机通过可转动叶片可改变其倾角来调节流量和风压,它是一种能在大范围负荷变化下进行调节的高效风机。对轴流式送风机常见故障的原因进行了分析,采取了相应的处理措施,取得了较好的效果。

The primary air forced draft fans of the boiler No.1 and No.2 of Huadian Baotou Power Generation Corporation Limited are axial flow fans with movable vanes;the air flow and the wind pressure of the fans can be adjusted by changing the dip angles of the movable vanes;so the fans have high efficiency and are adjustable under the load variation in large range.The reasons of the common faults of the axial flow forced draft fan were analyzed,and after the relevant treatment measures were adopted,the better effects have been obtained.
