液压防爆提升机的故障诊断在液压系统中是一个新的课题。笔者在使用维修液压防爆提升机的过程中积累了一些工作经验,共同行参考。 1 故障的种类及原因液压防爆提升机的故障具有多样性,液压系统发生故障的原因往往与选用的液压油、液压系统清洁度、液压元件及使用操作有直接联系。造成故障的主要原因有:①安装时调整和找正有误差,底座强度不够等造成振动,从而导致液压泵或马达损坏;②拆装时管路内进入灰尘或液压油不清洁,使液压元件磨损;③液压油混入冷却液,使液压油变质;④液压油箱油量少,油泵吸入空气,引起系统噪声与抖
Hydraulic explosion-proof hoist fault diagnosis in the hydraulic system is a new topic. I used in the process of maintenance of hydraulic explosion-proof hoist has accumulated some work experience, common reference. 1 types and causes of failure Hydraulic explosion-proof hoist failure has a variety of reasons, the hydraulic system failure often associated with the selection of hydraulic oil, hydraulic system cleanliness, hydraulic components and the use of direct operation. The main reasons for the failure are: ①Installation of the adjustment and alignment errors, insufficient base strength caused by vibration, resulting in damage to the hydraulic pump or motor; ② disassembly into the pipeline into the dust or hydraulic oil is not clean, the hydraulic components Wear and tear; ③ hydraulic oil mixed with coolant, hydraulic oil deterioration; ④ less fuel tank, the pump inhaled air, causing system noise and shaking
