固定式升降機(jī)http://www.it616.com.cn/液壓系統(tǒng)本身具有很多優(yōu)越性，但是由于油泵，閥類結(jié)構(gòu)緊湊精密，使用中稍有不慎就會(huì)發(fā)生閥芯賭卡現(xiàn)象，從而使整個(gè)系統(tǒng)失靈，以造成不堪設(shè)想的嚴(yán)重后果，據(jù)統(tǒng)計(jì)固定式升降機(jī)系統(tǒng)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.
固定式升降機(jī)http://www.it616.com.cn/泵、換向閥、油缸等原件正常磨損會(huì)產(chǎn)生的金屬顆粒，密封元件磨損產(chǎn)生的橡膠制顆粒以及濾油器產(chǎn)生的脫落物，生產(chǎn)和維修過程中對(duì)原件的不恰當(dāng)清洗時(shí)造成污染的主要原因。這種不恰當(dāng)?shù)那逑纯墒构ぷ饔鸵褐谐霈F(xiàn)棉紗等織物纖維，另外機(jī)械加工中產(chǎn)生的沙礫和碎片，焊接管路上的氧化物、熔渣及研磨后的殘余物等都可鞥污染油液。空氣中的塵埃，顆粒在打開泵和閥時(shí)也可能進(jìn)入系統(tǒng)而造成污染，維修中由于固定式升降機(jī)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.
