矿制车间上料系统收尘设备主风机型号为4-72NO.12D离心式风机,该风机的轴端面密封采用毛毡密封,运转时轴承箱两端面的密封漏油严重,夏季气温高或轴承发热时漏油更严重。这样既浪费油,风机又不能正常运转,需要停车检修更换毛毡,而且检修麻烦工期较长,造成上料皮带系统环境卫生差。
Dust collection equipment for the main mill workshop The main blower model is 4-72NO.12D centrifugal blower. The shaft seal of the blower is sealed by felt. When the operation is over, the seal on both ends of the bearing box leaks seriously. In summer, the temperature is high or the bearing is hot When the spill more serious. This is a waste of oil, the fan can not operate normally, you need to stop the maintenance of replacement felt, and overhaul troubles a longer period of time, resulting in poor environmental hygiene belt system.
