我局有一台宝马（BOMAG）稳定土拌和机，因主液压泵压力降低，导致不能正常工作，入厂进行检修。经检查，发现主液压泵油液中混有铜末，判定为配流盘磨损，引起主液压泵压力降低，主机不能正常工作。拆检主液压泵发现，主被动配流盘全部磨损，出现明显划痕。用平面磨床同时将两
I Bureau has a BMW (BOMAG) stabilized soil mixing machine, due to the main hydraulic pump pressure is reduced, resulting in not working, into the factory for overhaul. Upon examination, it was found that the main hydraulic pump fluid mixed with copper at the end, judged to wear with the flow plate, causing the main hydraulic pump pressure is reduced, the host can not work properly. Dismantling the main hydraulic pump found that the main passive with flow plate all wear and tear, obvious scratches. With a surface grinder at the same time two
