联合收割机的齿轮泵使用时间较长,如泵的压力不足、流量不够或有其他故障,一般不宜修理,应更换新泵。2001年麦收期间笔者共遇到5例齿轮泵泵体破裂现象,其中4例是新换齿轮泵试运转时泵体破裂的。可见机组人员对更换齿轮泵的知识还不大了解,下面说一下更换齿轮泵时的注意事项。 (1)更换新泵时一定要注意看清楚泵的额定工作压力、流量、旋向。如额定压力、流量与旧泵不相符可能会引起其
Combine harvester gear pump longer, such as the pump pressure is insufficient, the flow is not enough or have other faults, the general should not be repaired, the new pump should be replaced. During the 2001 wheat harvest, the author encountered a total of 5 cases of gear pump rupture, of which 4 cases were the pump body ruptured during the test run of the new gear pump. Visible crew on the replacement of gear pump knowledge is not yet understood, the following talk about replacement gear pump precautions. (1) Replace the new pump must pay attention to see the pump rated working pressure, flow, rotation. Such as the rated pressure, the flow does not match the old pump may cause it
