导轨式升降机液压缸内漏如何判断？

重庆导轨式升降机大多采用对称并联液压缸，迅速准确的判断故障缸显得很重要。将升降货梯动臂落到底，然后启动发动机(机器处于空挡位置)，将动臂操纵杆置于下降位置，加大油门根据松开动臂缸大腔接口处的漏油情况即可判断小腔油封的好坏。若大腔接口处漏油比较多，则说明该缸油封密封不良或油封损坏;若松开处接口不漏油可漏油很少，则说明该动臂缸小腔油封密封性能较好。大腔油封损坏，就会造成升起的动臂自动下落，其判断方法与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.

也可用此法来判断重庆导轨式升降机的翻斗缸或转向缸的某一缸油封以及非对称式液压缸的斗杆缸、铲斗缸)的某一腔油封的密封情况。由此及时发现问题及时解决，避免因液压缸内漏得不到及时解决而耽误了重庆导轨式升降机的施工进程，造成不必要的损失。
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.
