小四轮液压柱塞泵不泵油的原因很多,如液压油油量不足,分离手柄未放在接合位置,安全阀与单向阀漏油严重,柱塞回位弹簧折断,液压油内混入大量的气体等。此外,在实际工作中,柱塞悬空也是不泵油的原因之一。这种故障多发生在液压泵重新安装以后。现对造成液压泵柱塞悬空的原因及排除方法作一介绍。 1.液压泵三个紧固螺栓扭紧力不均,泵体支口在盖座孔内别劲,产生微量变形,使柱塞在泵体内产生卡滞,柱塞回位弹簧不能使其回位,造成柱塞悬空,不能泵油。当反复扳动分离手柄时,只能感到有
Small four-wheel hydraulic piston pump does not pump oil for many reasons, such as insufficient hydraulic oil, the separation handle is not placed in the joint position, safety valve and one-way valve leakage serious, the plunger return spring break, mixed with hydraulic oil A lot of gas and so on. In addition, in practical work, the plunger is also one of the reasons not to pump oil. This failure occurred in the hydraulic pump after the reinstallation. The cause of the hydraulic pump plunger is left open and the reasons for the elimination of an introduction. 1. Hydraulic pump three tightening bolts tightening uneven, pump body mouth hole in the lid hole, resulting in slight deformation, so that the plunger in the pump body jamming, the plunger return spring can not make it back Bit, causing the plunger to float, can not pump oil. When you repeatedly pull the separation handle, you can only feel it
