升降機油缸是用來進行升降功能的，但是如果油缸壞了應該如何進行修理呢？

1、首先應開動液壓系統，將活塞的位置借助液壓力移到適于拆卸的一個頂端位置，進行拆卸之前，切斷電源，使液壓裝置停止運動。
Lift manufacturers mentioned hydraulic system should first start, the position of the piston is moved by means of hydraulic pressure suitable for the demolition of a top position, prior to the demolition, cutting off power to stop the movement of the hydraulic system.
   
2、說為了分析液壓缸的受力情況，查找液壓缸的故障及損壞原因，在拆卸液壓缸以前，對主要零部件的特征、安裝方位如缸筒、活塞桿、活塞、導向套等，應當做上記號，并記錄下來。
Lift manufacturers say that in order to analyze the forces of the hydraulic cylinder, hydraulic cylinder failure and find the cause of damage in the cylinder before the demolition of the main characteristics of components, installation position as cylinder, piston, piston guide sleeve, etc., should be cook mark, and recorded.
   
3、為了將液壓缸從設備上卸下，先將進、出油口的配管卸下，活塞桿端的連接頭和安裝螺栓等需要全部松開。拆卸時，應嚴防損傷活塞桿頂端的螺紋、油口螺紋和活塞桿表面。拆卸中，不合適的敲打以及突然的掉落，都會損壞螺紋，或在活塞桿表面產生打痕。
Manufacturers said that in order to lift the hydraulic cylinder is removed from the device, the first into and out of the mouth of the pipe to remove the oil, connectors and mounting bolt rod ends and other needs of the entire release. Demolition, should prevent damage threaded rod, threaded ports and the top surface of the piston rod. Demolition, inappropriate beat and sudden fall, will damage the thread, or create hit marks on the rod surface.
   
4、由于液壓缸的結構和大小不同，拆卸的順序也稍有不同.一般應先松開端蓋的緊固螺栓或連接桿，然后將端蓋、活塞桿、活塞和缸筒順序拆卸。在拆出活塞與活塞桿時，須注意不應硬性將它們從缸筒中敲出，以免損傷缸筒內表面。
Because different manufacturers remind lift structure and size of the hydraulic cylinder, a slightly different order of disassembly. Usually first loosen the fastening bolt or a connecting rod cap, and then the end cap, the piston rod,the piston and cylinder disassembly sequence. In the demolition of the piston and piston rod should be noted that they are not hard knock from the cylinder in order to avoid damage to the cylinder surface.
