装载机直轴斜盘式柱塞泵分为压力供油型的自吸油型两种。压力供油型液压泵大都采用有气压的油箱，也有液压泵本身带有补油分泵向液压泵进油口提供压力油的，自吸油型液压泵的自吸油能力很强，无需外力供油，对于自吸油型柱塞泵，液压油箱内的油液不得低于油标下限，要保持足够数量的液压油。液压油的清洁度越高，液压泵的使用寿命越长。
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.
 
装载机靠气压供油的液压油箱，在每次启动机器后，必须等液压渍箱达到使用气压后，才能操作机械。如液压油箱的气压不足时就担任机器，会对液压泵内的与滑鞭造成拉脱现象，出会造成泵体内回程板与压板的非正常磨损。山东装载机http://www.132p.cn/操作人每日需对柱塞泵检查1-2次，检查液压泵运转声响是否正常，如发现液压缸速度下降或闷车时，就应该对补油泵解体检查，检查叶轮边沿是否有刮伤现象，内齿轮泵间隙是否过大。
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.
