这个呢就是高压油泵主要的造型,首先我们可以看到油油是怎么上来的,他肯定是要有齿轮泵把他带上来的,齿轮泵呢就是说这两个孔在后面分别装的两根管子,一个是进油的, 一个出油的就从这个出油口从这里吸进来,在里面齿轮泵转一圈,然后从这个出口出来到精滤上面,精滤上面到了之后到这个精油螺丝这里进去,就是往油面油泵里面进了,然后需要注意一点就是这个螺丝上面有一个滤网,滤网 要经常清洗,因为柴油脏了,经常清洗,或者说油箱有脏东西了也要经常清洗。首先有一个事情,就是说这个滤网一定不能取,不管你油再脏,或者是说你看着滤网再脏,你都不要去把它取扔掉,因为这个滤网是保护油泵柱塞和内部 传感器以及喷油器的最后一道屏障,这个东西如果你取了之后会非常的容易坏,柱塞和喷油器这个一定要注意啊。还有一个非常关键的一个东西,可以看到这里是不是有一个螺丝,一个内六角的螺丝,然后就说这个螺丝是一个非常关键的一个东西,它叫做零流量孔, 好多师傅就是没在意这个东西,它这个螺丝就是一个堵头,就是你把这个螺丝拆掉之后,它会往外面流油,就多余的 油泵多余的油从这里流出来了,如果说你空气过多的话,他是存这里排空气用的,如果说这个螺丝堵了之后,就是说造成你轨压过高, 造成你轨压过高,然后吸压阀打开,你怎么修都修不住,有的师傅不知道这个东西的话,没检测过的话可能会说我把油泵换了好了,就是油泵的问题,但是说你单独的,不管是换 堵塞还是换计量单元,还是换齿轮泵回油螺丝这些都解决不了,只有换总成才能解决,很大概率就是说这个零流量孔堵了导致的。

i'll explain the overhaul procedure of fuel injection pump handle the fuel injection pump with care because it has been made precisely in order to display a combustion and governor performance prepare the exclusive tool to overhaul the engine firstly remove the relative pipes secondly lou in the bolt of delivery valve, thirdly loosen the tightening nut of fuel injection pump with the exclusive socket wrench detach the supporting nut of fuel rack and then remove the pump i'll explain the disassembly procedure of fuel injection pump disassemble the fuel injection pump as you are watching in the video prepare the exclusive tool to overhaul the fuel injection pump turn the fuel injection pump to 180 degrees on the table and set the exclusive tool to draw the plunger guide on the rear side of flung in the fuel injection pump body turn the support bolt of exclusive tool to clockwise and hold the plunger guide remove the circlip for stopper of plunger guide while holding it 嗯, rise the plunger guide by the spring force when turning the support bolt of tool 2 counterclockwise after detaching tool it is possible to remove the plunger guide, spring sheet, plunger, spring retainer and pinion together to touch the rack lock bolt and remove the rack remove the deflector which is set to the center of fuel injection pump there are two deflectors next attach the support bolt of delivery valve with the hexagonal wrench and remove the delivery valve pen square ring be careful not to lose parts of delivery valve because they are too small finally to touch the bolt of barrel holder and remove the barrel from the pump body o ring is equipped at the barrel position of fuel injection pump so make sure to remove it the overhaul of fuel injection pump will be completely wash the disassembled parts and check for every。

玩柴飞,加入我主页抖音群,交流玩车心得,一起轻松玩车无压力!车友们,我的高压油泵最近有点渗油,对于我这个强迫症患者来说,绝对不允许出现这种情况。原本想着买个油泵到修理厂换下,但是咨询了车友, 据说就是三个螺丝,很简单,所以就想自己换的试试,结果又翻车了,打不着了,又找拖车拖到修理厂。下面先看下我是怎么换油泵的。 第一步,先把中冷和相关管路都拆掉,这个我就不详细介绍了,不会拆的可以看我之前的视频。然后就是拆高压油泵,油泵与发动机就是三个螺丝连接,但是位置较小,需谨慎操作, 当心螺丝掉落。拆螺丝之前记得把油泵上的油管依次拆掉,拆完之后要注意了,这时候慢慢把油泵取出来,快取出来的时候要特别小心,因为油泵和发动机之间还有个小连接配件,我就是因为没注意这个小配件掉落到发动机里了,导致后来一直没能打着车。换新油泵的时候记得一定要装上这个小连接配件, 然后再依次恢复安装。以上就是我更换油泵的具体操作细节了,虽然原理简单,但是实操还需要特别细致,才能保证万无一失。好了,希望我的分享能对你有所帮助,感谢观看,下期再见!
