3、加速橡胶密封件老化变质,寿命缩短,甚至丧失其密封性能,使挖掘机液压泵系统严重泄漏。

4、油液汽化、水分蒸发,容易使挖掘机液压泵元件产生穴蚀;油液氧化形成胶状沉积物,易堵塞滤油器和挖掘机液压泵阀内的小孔,使挖掘机液压泵系统不能正常工作。

对于大型挖掘机挖掘机液压泵油散热系统(更确切地说应为挖掘机液压泵油温控制系统)的改善,虽然各厂家采用的具体方式有所不同,但基本思路却是一样的,既能使挖掘机液压泵油温度在连续作业中平衡在较为理想的范围内,又能使挖掘机液压泵系统在冷态下投入工作时能迅速升温(达到油正常工作温度范围)

为实现此目的,系统参数匹配至按技术要求使极限载荷调定值低于回路中初级压力阀的调定值;否则,初级压力阀打开将会导致溢流过热。同时,挖掘机7星彩液压泵维修检查比例电磁阀工作是否正常,此项工作一定要严格按照标准要求进行,必要时应对系统相关参数进行恢复性调整。
