桃林铅锌矿选厂原三台球磨机的润滑油均由油泵直接供给,每台球磨机配有二台油泵。以往十几年的生产中,由于油泵发生故障断油,造成球磨机空心轴瓦烧坏的重复性事故三、四起,每次停产检修都给国家造成巨大损失。批林批孔运动以来,他们将球磨机的三处六台油泵供给润滑油改为自动集中供油。 Taolin lead-zinc ore mill selected three ball mill lubricants are directly supplied by the pump, each ball mill with two pumps. In the past more than 10 years of production, due to pump failure oil, causing the ball mill hollow bearing burn repeated repetitive accidents three or four, each stop production overhaul have caused tremendous losses to the country. Since Lin approved the campaign, they changed the lubrication oil supplied by the three six-ball pumps of the ball mill into an automatic centralized fuel supply.
