?活塞環(huán)損壞或氣缸套損壞所致的振動力不平衡,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,還有一個重要的原因是發(fā)動機怠速工況噪聲增大,為了保證發(fā)動機處于良好狀態(tài)需要對缸內(nèi)進行冷卻水冷卻。
這就會產(chǎn)生很多影響發(fā)動機運行質(zhì)量的因素產(chǎn)生噪聲——尤其在高速下,噪聲會急劇增大,從而對發(fā)動機產(chǎn)生巨大的影響4.柱塞泵長期使用就會產(chǎn)生磨損,其磨損主要表現(xiàn)為:進油口磨損、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)動機內(nèi)部,在缸壁上留下一個孔洞和污物進入活塞;然后排出到缸筒里,這樣就會加大活塞與缸壁粘結(jié)力而形成噪音因此,在實際使用中最好的方法就是保證車輛發(fā)動機經(jīng)常處于良好運行狀態(tài),對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、軸套等零件磨損嚴重時,應更換磨損零件,對間隙進行調(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??;如果間隙過大,則齒輪與柱塞泵嚙合不緊密,甚至造成齒輪燒毀。
當齒輪與軸之間沒有間隙時,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。
此時需要在軸承腔內(nèi)加入潤滑油,調(diào)節(jié)潤滑油的量以及潤滑脂來降低泵內(nèi)的油溫,同時還需要更換泵體內(nèi)磨損的零件,將泵體清理干凈之后對泵進行修理 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。
