CB－32型油泵（重庆探旷厂制造）在生产中，一般运转一年左右，由于高压侧产生的对低压侧的径向推力，使泵壳的齿轮接触面处产生大于齿宽0.4～0.7毫米的槽沟。而齿轮油泵的高压侧壳体，一般没有多大磨损。以前，我们用旧后均不作修理，等钻机大修或油泵出现故障后，就换新的油泵。去年，我们自己搞革新，将泵壳旋转180°，即原来的吸油 The CB-32 type oil pump (manufactured by Chongqing Exploration Plant) is generally operated for about one year. Due to the radial thrust to the low pressure side generated by the high pressure side, the gear contact surface of the pump housing is larger than the tooth width 0.4 to 0.7. Millimeter groove. The high pressure side housing of the gear oil pump generally does not have much wear. Previously, we did not make repairs after using the old ones. When the drilling rigs were overhauled or the oil pumps failed, they were replaced with new ones. Last year, we made innovations ourselves by rotating the pump casing 180°, the original suction
