齿轮泵及马达与柱塞泵内部的零件磨损和壳体的磨损，还有油封磨损，油封老化等问题。泵内部零件的磨损会造成内漏，其中轴套和齿轮端面之间泄漏面积大，是造成漏油的主要部位。磨损内漏是齿轮泵容积效率，造成泵输出功率远远小于输入功率。因为齿轮柱塞在壳体内不停的旋转，必然会产生一定的热能，很容易引起泵过油，加剧零部件磨损。壳体的磨损主要是轴套孔的磨损，（齿轮轴与轴套的正常间隙0.09~0.175mm，大不得超过0.20mm）。

Gear pump and motor and piston pump internal parts wear and shell wear, as well as oil seal wear, oil seal aging and other problems. The wear of the pump internal parts will cause internal leakage, which is caused by the large leakage area between the shaft sleeve and the gear end face, is the main part of oil leakage. Wear leakage is gear pump volume efficiency, resulting in pump output power is far less than the input power. Because the gear plunger keeps rotating in the shell, it is bound to produce a certain amount of heat energy, which is easy to cause the pump over oil and aggravate the wear of parts. The wear of the shell is mainly the wear of the shaft sleeve hole, (the normal gap between the gear shaft and the shaft sleeve is 0.09~0.175mm, not more than 0.20mm).
