鹤岗选煤总厂30m周边传动耙式浓缩机中心轴承为推力球轴承,一直采用人工注油方式。因中心轴承位置距离浓缩机最深处有8.5m,电源碳刷位于中心轴承附近,必须停车停电后,由作业人员爬到注油点将黄油涂抹进去。因注油效果较差,并且不能连续注油,导致轴承磨损严重,使用寿命缩短。为 Around 30m around Hegang Coal Preparation Plant, the central bearing of rake thickener is thrust ball bearing, which has been adopting manual oiling method. Because the center bearing position from the deepest thickener has 8.5m, power carbon brush located near the center bearing, must be stopped after power failure, climbed to the greasing point by the operator smear the butter into it. Due to poor oiling effect, and can not be continuous oiling, resulting in serious bearing wear and tear, shortened service life. for
