摘要
NK-160全液压汽车起重机因长时制、超负荷工作,使液压油温升过高,密封件老化变质而丧失密封性能,影响机器的正常运行。在回油路上增加冷却器,使用效果理想。
After prolonged working, the temperature of the hydraulic oil inside full hydraulic crane becomes so high which reduces the sealing ability of the seals to a large extent, and in turn affects the proper operation very much. The cooling system implemented inside the crane will eliminate such negative effects and increase the efficiency .
