液压油缸在工程机械中起着重要的作用.油缸出现泄漏时,机械效率降低,严重时无法工作.液压油缸主要由缸体、活塞杆、导向套以及各种密封件组成.在更换密封件时,由于多数油缸的导向套是靠卡键和弹性档环固定在缸体上的,这样缸体上的卡键槽就成为拆装活塞组合件的主要障碍.在拆装油缸时,直接抽拉活塞杆往往会使活塞上的油封或密封环卡在键槽内,用力抽拉容易损坏活塞和缸体的接合面.严重时会出现缸体和
The hydraulic cylinder plays an important role in the construction machinery. When the cylinder leaks, the mechanical efficiency decreases, and when it is serious, it cannot work. The hydraulic cylinder is mainly composed of a cylinder block, a piston rod, a guide sleeve and various seals. When the seal is replaced Because most of the cylinder’s guide sleeve is fixed on the cylinder by the card key and elastic ring, so the key groove on the cylinder block becomes the main obstacle to disassemble and disassemble the piston assembly. When disassembling the cylinder, directly pull the piston. The rod often causes the oil seal or the seal ring on the piston to get stuck in the keyway. Pulling it hard can easily damage the joint surface between the piston and the cylinder. In severe cases, the cylinder and
