齿轮泵

“齿轮泵窜油”，即液压油将骨架油封击穿而溢出。此现象普遍存在，主机厂反映强烈，齿轮泵窜油严重影响装载机的正常工作和齿轮泵的使用可靠性及环境污染。为利于问题的解决，现对齿轮泵油封窜油故障的原因和控制方法进行分析。 1.零部件制造质量的影响

实际流量是指泵(或马达)工作时出口处(或进口处)的流量。由于泵本身存在内泄漏，其实际流量小于理论流量。由于马达本身也存在内泄漏，要实现转速，为补偿泄漏量，其输入实际流量必须大于理论流量。CTR3-050/P5.5/GP2-0158/C410N

第二是阻尼器(3)堵塞，油压传递不到锥阀上，导阀就失去了支主阀压力的调节作用。阻尼器(小孔)堵塞后，在任何压力下锥阀都不会打开溢流油液，阀内始终无油液流动，主阀上下腔压力一直相等，由于主阀芯上端环形承压面积大于下端环形承压面积，所以主阀也始终关闭，不会溢流，主阀压力随负载增加而上升。当执行机构停止工作时，系统压力就会无限升高。除这些原因以外，尚需检查外控口是否堵住，锥阀安装是否良好等。
