我矿选厂在生产上使用了一批4PNJ、4(1/2)PSJ挂胶杂质泵。这些泵的轴承都是用机械油润滑,漏油十分严重。漏油的主要原因是轴承两端压盖上的毛毡垫受力不匀,油池又是卧式的,机械油油面又高,毛毡垫稍有毛病就渗漏。为此,我们改用2号工业锂基脂代替机械油润 I use a number of mining plant in the production of a number of 4PNJ, 4 (1/2) PSJ plastic hanging impurities pump. These pump bearings are lubricated with mechanical oil, oil spills are very serious. The main reason for the oil leakage is that the felt pad on the gland at both ends of the bearing is unevenly pressed, the oil pool is horizontal, the oil level of the mechanical oil is high, and the felt pad slightly leaks. To this end, we use the No. 2 industrial lithium base grease instead of mechanical oil
