裝載機(jī)直軸斜盤(pán)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(wú)需外力供油，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)。
Shandong loaders swashplate piston shaft straight into pressure from the sucking-two oil types. Pressure oil hydraulic pump powered by air pressure tank there, there are also pump up the oil itself with the cylinder to provide pressure

oil pump inlet port, the self-absorbing ability of strong self-suction type pump, no external oil supply for self-suction-type piston pump, the hydraulic oil tank shall not be less than the lower limit of the oil standard, to maintain a sufficient number of hydraulic oil. The higher the cleanliness of hydraulic oil, the longer pump life.
 
裝載機(jī)靠氣壓供油的液壓油箱，在每次啟動(dòng)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(huì)對(duì)液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會(huì)造成泵體內(nèi)回程板與壓板的非正常磨損。山東裝載機(jī)http://www.hpize.cn/操作人每日需對(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。
After Shandong loader by hydraulic pressure of the oil tank after each start the machine, such as hydraulic stains box must use air pressure to operate machinery. Has served as insufficient hydraulic tank pressure machine, and slip inside the pump would cause whip pull off phenomenon, can cause abnormal wear of the pump body board and return the platen. Shandong loader operator to check the daily need for piston pump 1-2 times, check the pump running sound is normal, such as hydraulic cylinders found slowdowns or stuffy car, you should check for the disintegration of the charge pump, check whether the impeller edge scratching phenomenon, internal gear pump gap is too big.
