柱塞向上供油，當(dāng)上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時(shí)，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，采用補(bǔ)油泵供油的柱塞泵，使用3000h后，操作人員每日需對(duì)柱塞泵檢查1-2次，檢查液壓泵運(yùn)轉(zhuǎn)聲響是否正常。如發(fā)現(xiàn)液壓缸速度下降或悶車(chē)時(shí)，就應(yīng)該對(duì)補(bǔ)油泵解體檢查，檢查葉輪邊沿是否有刮傷現(xiàn)象，內(nèi)齒輪泵間隙是否過(guò)大。對(duì)于自吸油型柱塞泵，液壓油箱內(nèi)的油液不得低于油標(biāo)下限，要保持足夠數(shù)量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長(zhǎng)。柱塞泵重要的部件是軸承，放松柱塞立即縮回原位，表明柱塞副密封良好，否則應(yīng)更換柱塞副。(4)檢查出油閥副減壓環(huán)帶是否磨損有臺(tái)階或傷痕現(xiàn)象，必要時(shí)應(yīng)予以更換。(5)檢查出油閥副的配合情況。用手指堵住出油閥下孔，用另一手指將出油閥輕輕向下壓，當(dāng)手指離開(kāi)出油閥上端時(shí)，它能自動(dòng)彈回原位，表明出油閥副密封良好如果軸承出現(xiàn)游隙出油閥在彈簧力的作用下迅速關(guān)閉，停止供油。此后柱塞還要上行，當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后，在彈簧的作用下，柱塞又下行。此時(shí)便開(kāi)始了下一個(gè)循環(huán)
