2、油泵壳体的磨损主要是浮动轴套孔的磨损(齿轮轴与轴套的正常间隙是0.09~0.175mm，大不得过0.20mm)。齿轮工作受压力油的作用，齿轮尖部靠近油泵壳体，磨损泵体的低压腔部分。另一种磨损是壳体内工作面成圆周似的磨损，这种磨损主要是添加的油液不净所致，所以必须添加没有杂质的油液。

柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。

        由于高粘度齿轮泵输送的介质粘度较高，为减小流动阻力，提高泵的吸液能力，必须对介质进行加热或保温。通常采用电热元件加热，可使粘性液体受热均匀。若温度波动不大，输送的高粘度液体容易发生降解时，建议采用流体加热方式，特别是排量大的齿轮泵。流体加热又分内置、外置式结构。所谓内置式是指在齿轮泵泵体或端盖的内部设计突热套，外置式则是通过螺栓将夹热套与泵体联接在一起。往夹套内通入蒸汽、导热油，还是冷却水，要根据介质具体情况而定。内置式适用于对输送液体温度均匀性要求较高，或要求对高温液体进行均匀冷却的场合。当电加热方式缺乏安全性或对温度控制要求不高时，可采用外置式结构。美国VIKING公司生产的内啮合齿轮泵，其泵头部分的夹套可以对输送流体的温度进行控制，无论是在高温或低温环境下，均可带外置式夹套。
