固定式升降机液压泵站的故障是如何形成的？

固定式升降机http://www.jntr168.com/液压系统本身具有很多优越性，但是由于油泵，阀类结构紧凑精密，使用中稍有不慎就会发生阀芯赌卡现象，从而使整个系统失灵，以造成不堪设想的严重后果，据统计固定式升降机系统故障70%以上是由于油液污染造成的。
Stationary hydraulic lift system itself has many advantages, but due to oil pump, valve structure compact precision, using slightly carelessly will spool gambling card phenomenon, so as to make the whole system failure, resulting in disastrous consequences, according to the statistics fixed lifting machine system fault 70% above is due to oil pollution. 
 
固定式升降机http://www.jntr168.com/泵、换向阀、油缸等原件正常磨损会产生的金属颗粒，密封元件磨损产生的橡胶制颗粒以及滤油器产生的脱落物，生产和维修过程中对原件的不恰当清洗时造成污染的主要原因。这种不恰当的清洗可使工作油液中出现棉纱等织物纤维，另外机械加工中产生的沙砾和碎片，焊接管路上的氧化物、熔渣及研磨后的残余物等都可鞥污染油液。空气中的尘埃，颗粒在打开泵和阀时也可能进入系统而造成污染，维修中由于固定式升降机操作不慎而混入污染物。
Fixed type lift pump, reversing valves, cylinders and other original normal wear will produce metal particles, sealing element abrasion of rubber particles and oil filter of exfoliation, in the process of production and maintenance of the original pollution caused by improper cleaning. The inappropriate washing oil in cotton woven fabric, also in machining of gravel and debris, welding pipe oxide, slag and after grinding the remnants are eng oil pollution. Dust in the air, particles in the open pump and valve may also enter the system and cause pollution, repair due to the fixed elevator operation accidentally mixed with pollutants.
