ＷＺ—１５０Ｂ装岩机在作业过程中受砂粒灰尘污染严重，加之其上的输送轴等需润滑部位工作负荷大、工作时间长和油温高，而原机采用手工润滑方式，造成某些隐藏或难以接触的润滑点易被忽略而长期没有润滑。机器表面上的砂粒灰尘随干油脂挤进轴承和螺栓内，使磨损更加严重，施 WZ-150B rock loader in the course of operations by the sand dust pollution, coupled with its transmission shaft and other parts to be lubricated work load, long working hours and high oil temperature, and the original machine using manual lubrication, resulting in some hidden Or hard-to-reach lubrication points are easily overlooked and are not lubricated for a long time. The dust on the surface of the machine is squeezed into the bearings and bolts with dry grease to make the wear more serious.
