油封磨損，膠封老化卸荷片的橡膠油封老化變質(zhì)，失去彈性，對(duì)高壓油腔和低壓油腔失去了密封隔離作用，會(huì)產(chǎn)生高壓油腔的油壓往低壓油腔，稱(chēng)為"內(nèi)漏"，它降低了油泵的工作壓力和流量。CB46齒輪泵它的正常工作壓力為100~110kg/平方厘米，正常輸油量是46L/min，標(biāo)準(zhǔn)的卸荷片橡膠油封是57×43。自緊油封是PG25×42×10的骨架式油封，它的損壞或年久失效，空氣便從油封與主軸軸頸之間的縫隙或從進(jìn)油口接盤(pán)與油泵殼體結(jié)合處被吸入油泵，經(jīng)回油管進(jìn)入油箱，在油箱中產(chǎn)生大量氣泡。會(huì)造成油箱中的油液減少，發(fā)動(dòng)機(jī)油底槽中油液增多現(xiàn)象，使農(nóng)具提升緩慢或不能提升。必須更換油封才可排除此故障。
