    装载机液压泵的供油形式

    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。
    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.
     
    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。采用补油泵供油的柱塞泵,使用3000h后,操作人员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 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.
     
    装载机对于自吸油型柱塞泵,小型装载机、莱州装载机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 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.
