重慶導(dǎo)軌式升降機(jī)大多采用對稱并聯(lián)液壓缸，迅速準(zhǔn)確的判斷故障缸顯得很重要。將升降貨梯動(dòng)臂落到底，然后啟動(dòng)發(fā)動(dòng)機(jī)(機(jī)器處于空擋位置)，將動(dòng)臂操縱桿置于下降位置，加大油門根據(jù)松開動(dòng)臂缸大腔接口處的漏油情況即可判斷小腔油封的好壞。若大腔接口處漏油比較多，則說明該缸油封密封不良或油封損壞;若松開處接口不漏油可漏油很少，則說明該動(dòng)臂缸小腔油封密封性能較好。大腔油封損壞，就會(huì)造成升起的動(dòng)臂自動(dòng)下落，其判斷方法與小腔油封判定方法相反。

Guiyang guide rail lift is mostly used in symmetrical parallel hydraulic cylinders, quickly and accurately determine the fault cylinder is very important. Will lift elevator boom down in the end, and then start the engine (machine is in a neutral position), boom lever is arranged in the lowered position, increase the throttle to loosen the boom cylinder cavity interface oil can be judged cavity seal is good or bad. If the cavity interface leakage more, then the cylinder seal sealing oil seal is bad or damaged; if undo interface does not leak oil can leak rarely, the boom cylinder cavity seal sealing performance is better. The large cavity oil seal is damaged, it will cause the rising boom automatically fall, the judgment method and determination method of opposite seal cavity.

也可用此法來判斷重慶導(dǎo)軌式升降機(jī)的翻斗缸或轉(zhuǎn)向缸的某一缸油封以及非對稱式液壓缸的斗桿缸、鏟斗缸)的某一腔油封的密封情況。由此及時(shí)發(fā)現(xiàn)問題及時(shí)解決，避免因液壓缸內(nèi)漏得不到及時(shí)解決而耽誤了重慶導(dǎo)軌式升降機(jī)的施工進(jìn)程，造成不必要的損失。
This method can also be used to determine the Guiyang guide rail type lifter turning bucket cylinder or steering cylinder of a cylinder seal and non symmetrical hydraulic cylinder of the bucket rod cylinder, bucket cylinder) of a cavity seal seal. From time to time to find the problem solved in time to avoid the leakage of the hydraulic cylinder can not be resolved in a timely manner to delay the construction process of Guiyang guide rail lift, resulting in unnecessary losses.
