为了保证圆锥破碎机正常工作，减少因润滑不良造成的故障，我们于1991年对我厂8台圆锥破碎机回油管路进行了改造。改造后几年的实践表明，效果很好，扭转了过去破碎机润滑不良，确形瓦甩油或止口处溢油的被动局面。具体改进方法如图1、2所示。在主回油管路的第一个弯管处增加了
In order to ensure the normal operation of the cone crusher to reduce the failure caused by poor lubrication, we in 1991, my plant eight cone crusher back to the oil pipeline has been transformed. The practice after several years of reconstruction shows that the effect is very good, reversing the passive situation that the crusher in the past was badly lubricated, the elctric tile slips the oil, or spills oil at the stop. Specific improvements shown in Figure 1,2. Added to the first bend in the main return line
