?活塞環(huán)損壞或氣缸套損壞所致的振動(dòng)力不平衡，這種現(xiàn)象就是產(chǎn)生柱塞泵泵軸軸承、泵殼之間所存在的間隙，主要的是這種間隙也是泵軸與泵殼之間的間隙，還有一個(gè)重要的原因是發(fā)動(dòng)機(jī)怠速工況噪聲增大，為了保證發(fā)動(dòng)機(jī)處于良好狀態(tài)需要對(duì)缸內(nèi)進(jìn)行冷卻水冷卻。
這就會(huì)產(chǎn)生很多影響發(fā)動(dòng)機(jī)運(yùn)行質(zhì)量的因素產(chǎn)生噪聲——尤其在高速下，噪聲會(huì)急劇增大，從而對(duì)發(fā)動(dòng)機(jī)產(chǎn)生巨大的影響4.柱塞泵長(zhǎng)期使用就會(huì)產(chǎn)生磨損，其磨損主要表現(xiàn)為：進(jìn)油口磨損、軸頭破損、密封圈磨損、軸頭與泵殼磨損等。
通過油嘴泄漏到發(fā)動(dòng)機(jī)內(nèi)部，在缸壁上留下一個(gè)孔洞和污物進(jìn)入活塞；然后排出到缸筒里，這樣就會(huì)加大活塞與缸壁粘結(jié)力而形成噪音因此，在實(shí)際使用中最好的方法就是保證車輛發(fā)動(dòng)機(jī)經(jīng)常處于良好運(yùn)行狀態(tài)，對(duì)于油嘴的正常工作也需要定期檢查和保養(yǎng)，防止磨損增加或造成故障加劇。
如果在檢查齒輪、軸套等零件磨損嚴(yán)重時(shí)，應(yīng)更換磨損零件，對(duì)間隙進(jìn)行調(diào)整，并注意檢查泵軸與孔之間是否存在間隙如果間隙過小，則泵軸上的齒輪與柱塞泵接觸不良，摩擦系數(shù)較?。蝗绻g隙過大，則齒輪與柱塞泵嚙合不緊密，甚至造成齒輪燒毀。
當(dāng)齒輪與軸之間沒有間隙時(shí)，由于泵端徑向柱塞流量較大，而且齒輪與軸套之間嚙合間隙較小，因此，即使嚙合的是相同種類的零件，也不會(huì)發(fā)生泄漏如果間隙過小，則泵軸與孔之間的間隙過小，由于軸套之間摩擦系數(shù)較小而引起漏流體形成。
此時(shí)需要在軸承腔內(nèi)加入潤(rùn)滑油，調(diào)節(jié)潤(rùn)滑油的量以及潤(rùn)滑脂來降低泵內(nèi)的油溫，同時(shí)還需要更換泵體內(nèi)磨損的零件，將泵體清理干凈之后對(duì)泵進(jìn)行修理 90R180-KA-5-NN-80-S-M-C8-J-03-NNN-26-26-24 90R180KA5NN80SMC8J03NNN262624 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-26-26-24 90R180KA5NN80SMC8J03NNN262624 90R180-KA-5-NN-80-S-M-C8-J-03-NNN-29-29-24 90R180KA5NN80SMC8J03NNN292924 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-29-29-24 90R180KA5NN80SMC8J03NNN292924 90R180-KA-5-NN-80-S-M-C8-J-03-NNN-30-30-24 90R180KA5NN80SMC8J03NNN303024 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-30-30-24 90R180KA5NN80SMC8J03NNN303024 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-35-35-24 90R180KA5NN80SMC8J03NNN353524 90R180-KA-5-NN-80-S-M-C8-J-03-NNN-35-35-30 90R180KA5NN80SMC8J03NNN353530 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-35-35-30 90R180KA5NN80SMC8J03NNN353530 90R180-KA-5-NN-80-S-M-C8-J-03-NNN-42-42-24 90R180KA5NN80SMC8J03NNN424224 90-R-180-KA-5-NN-80-S-M-C8-J-03-NNN-42-42-24 90R180KA5NN80SMC8J03NNN424224 90R180-KA-5-NN-80-S-M-C8-J-04-NNN-42-42-24 90R180KA5NN80SMC8J04NNN424224 90-R-180-KA-5-NN-80-S-M-C8-J-04-NNN-42-42-24 90R180KA5NN80SMC8J04NNN424224 90R180-KA-5-NN-80-S-M-F1-H-03-FAC-32-32-24 90R180KA5NN80SMF1H03FAC323224 90-R-180-KA-5-NN-80-S-M-F1-H-03-FAC-32-32-24 90R180KA5NN80SMF1H03FAC323224 90R180-KA-5-NN-80-S-M-F1-J-05-FAC-38-38-28 90R180KA5NN80SMF1J05FAC383828 90-R-180-KA-5-NN-80-S-M-F1-J-05-FAC-38-38-28 90R180KA5NN80SMF1J05FAC383828 90R180-KA-5-NN-80-T-C-C8-H-03-NNN-26-26-24 90R180KA5NN80TCC8H03NNN262624 90-R-180-KA-5-NN-80-T-C-C8-H-03-NNN-26-26-24 90R180KA5NN80TCC8H03NNN262624 90R180-KA-5-NN-80-T-C-C8-H-03-NNN-42-42-24 90R180KA5NN80TCC8H03NNN424224 90-R-180-KA-5-NN-80-T-C-C8-H-03-NNN-42-42-24 90R180KA5NN80TCC8H03NNN424224 90R180-KA-5-NN-80-T-C-C8-J-03-NNN-23-23-30 90R180KA5NN80TCC8J03NNN232330 90-R-180-KA-5-NN-80-T-C-C8-J-03-NNN-23-23-30 90R180KA5NN80TCC8J03NNN232330 90R180-KA-5-NN-80-T-C-C8-J-03-NNN-26-26-24 90R180KA5NN80TCC8J03NNN262624 90-R-180-KA-5-NN-80-T-C-C8-J-03-NNN-26-26-24 90R180KA5NN80TCC8J03NNN262624 90R180-KA-5-NN-80-T-C-C8-J-03-NNN-29-29-24 90R180KA5NN80TCC8J03NNN292924 90-R-180-KA-5-NN-80-T-C-C8-J-03-NNN-29-29-24 90R180KA5NN80TCC8J03NNN292924 90R180-KA-5-NN-80-T-C-C8-J-03-NNN-42-42-26 90R180KA5NN80TCC8J03NNN424226 90-R-180-KA-5-NN-80-T-C-C8-J-03-NNN-42-42-26 90R180KA5NN80TCC8J03NNN424226。
