How to repair gear pump parts?

Or you may encounter a gear pump in a hydraulic pump, and you will find that long use will stop the pump in the hydraulic pump. Do you know why? In fact, it may be that the gear pump of the night banquet has a problem with the parts. In ordinary times we need to maintain the hydraulic pump of the gear pump, in fact we should also pay attention to the hydraulic pump of the small parts of the gear pump. The part of the gear pump in the hydraulic pump is to protect the gears, the pump body, the bearing seat ring, and also the long and short axis. The first is the tooth form repair: use fine emery cloth or the oil stone to remove pull or have worn the part of the multi-prismatic shape, then the gear meshes the surface to change the position and properly carry on the research, finally clean; For the serious wear that can be observed with the naked eye, the second is that we will encounter the wear of the gear when the surface is worn, and the burr will be removed by applying the oil stone. At the same time, changing gear meshing position, make originally not work meshing tooth surface of meshing, such not only can guarantee its original performance, can prolong the working life of the gear. The second part of the problem is the wear of our pump body, which is mainly in the contact between the cavity and the gear circle, and more happens on the oil suction side. If the pump body is symmetrical, the pump body can be rotated 180 degrees to be used again; If the pump body is non-symmetrical, it is necessary to repair the wear part of the cavity in the pump by electroplating bronze alloy process or brush plating. The above is the problem of some parts of the gear pump that we used in the hydraulic pump. Now you know the solution.
