1台SS400-23型稳定土拌和机刚启动时液压系统压力正常,工作一段时间后,随着液压油温度急剧上升,系统压力逐渐下降,直至拌和转子不能转动。检查液压油颜色呈灰黑色,且油液中有金属屑。分析认为:拌和机作业时产生大量飞扬的粉尘,从液压油箱的空滤器和活塞杆处进入液压系统中,由于液压油及过滤器没有定期更换,造成泵、马达严重磨损。磨损后产生的金属屑在液压油中流动,进一步加剧了其磨损,并使液
1 SS400-23 Stabilized Soil Mixer Just started hydraulic system pressure is normal, after a period of work, with the hydraulic oil temperature rose sharply, the system pressure gradually decreased until the mixing rotor can not rotate. Check the hydraulic oil color is gray-black, and oil in the metal shavings. Analysis shows that: Mixer operation produces a lot of flying dust, from the hydraulic tank air filter and piston rod into the hydraulic system, due to the hydraulic oil and filters are not regularly replaced, resulting in serious pump, motor wear. The metal shavings generated after the wear flow in the hydraulic oil further aggravate the wear and tear of the liquid
