液壓泵：直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無需外力供油。氣壓供油的液壓油箱，在每次啟動機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就擔(dān)任機(jī)器，會對液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會造成泵體內(nèi)回程板與壓板的非正常磨損。采用補(bǔ)油泵供油的柱塞泵，使用3000h后，操作人員每日需對柱塞泵檢查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時(shí)，就應(yīng)該對補(bǔ)油泵解體檢查，檢查葉輪邊沿是否有刮傷現(xiàn)象，內(nèi)齒輪泵間隙是否過大。
