应用负压密封原理解决风机轴承箱泄漏的方法

Solving the Leakage of Fan Bearing Box with the Negative Pressure Principle

风机轴承箱的泄漏尤其是风机主轴处动密封的泄漏一直是高炉风机运行存在的主要问题。应用负压密封原理,把风机入口处产生的负压通过管路引入轴承箱内,使轴承箱内产生一定负压。针对马钢某厂的集中风机的实际参数进行计算,并对这种密封方法进行了应用,取得了很好的效果。

The leakage of fan bearing box,especially the leakage of the moving sealing on the main shaft,is a main problem in the working fan of the furnace.With the princeiple of the negative pressure,the negative pressure at the inlet of the fan can be introduced into the bearing box through a pipe,resulting a certain negative pressure inside the bearing box.A calculation was made on the actual parameters of the central fans from a certain Masteel factory,then the method of such sealing was applied and a good effect was achieved..
