由于喷油泵挺柱体和挺柱体上的滑块配合不够紧,产生松动,导致滑块在泵体中运动时转动,经运转一段时间后把泵体滑块槽磨大,以致造成滑块肖折断,或在泵体中做无规则运动,严重时可把泵体挖成一个大洞穴,从而造成泵体报废。由于挺柱体失去园周向定位作用,导致外滚轮及凸轮轴损坏。 我们将报废的泵体根据其滑块槽的磨损情况,把其加工至10～15mm宽的槽,再加上一个滑块与其配合,泵体即可继续使用。
As the fuel pump tappet body and the tappet body with the slider is not tight enough, resulting in loose, causing the slider movement in the pump body rotation, after a period of operation of the pump body Slider groove grinding large, resulting in the slider Xiao broken, or in the pump to do a random movement, serious pump body can be dug into a large cave, resulting in pump scrapped. As the column body loses the role of circumferential positioning of the park, resulting in damage to the outer roller and camshaft. We will scrap the pump body according to its sliding groove wear, processing it to 10 ~ 15mm wide slot, coupled with a slider with its, the pump can continue to use.
