裝載機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，無需外力供油。
Shandong loaders straight axis swashplate piston into two kinds of pressure from the sucking oil type. Oil pressure hydraulic pump were powered by air pressure in the tank, but also pump up the oil itself with the cylinder to provide

pressure oil pump inlet. Since the suction-type pump self-absorbing ability is very strong, no external oil supply.
 
裝載機靠氣壓供油的液壓油箱，在每次啟動機器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就擔(dān)任機器，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，檢查液壓泵運轉(zhuǎn)聲響是否正常。如發(fā)現(xiàn)液壓缸速度下降或悶車時，就應(yīng)該對補油泵解體檢查，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。
After Shandong loaders by pressure hydraulic oil tank after each start the machine, such as hydraulic stains box must use air pressure, to operate machinery. Has served as insufficient hydraulic reservoir pressure machine, and slip inside the pump will cause whip pull off phenomenon, can cause abnormal wear of the pump body board and return the platen. Using up fuel supply to the piston pump, the use of 3000h, the operator checks the daily need for piston pump 1-2 times, check the pump running sound is normal. Found cylinder speed drops or stuffy car, you should pump up the disintegration of inspection, checking whether the impeller edge scratching phenomenon, the internal gear pump gap is too large.
 
裝載機對于自吸油型柱塞泵，小型裝載機、萊州裝載機液壓油箱內(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。
Shandong loader type piston pump for self-absorbing, small loaders, loader hydraulic oil Laizhou tank must not fall below the lower limit of the oil standard, to maintain a sufficient amount of hydraulic oil. Cleanliness of hydraulic oil higher, longer pump life.
