在带臂架的液压式工程机械上,都必须有变幅液压缸(或称动臂液压缸)推动其臂架运动,以使机械满足各种作业需要。 变幅液压缸在工作中虽然受到巨大复杂的力的作用,但只要使用正确,一般不容易出现故障。可当变幅液压缸受到外伤、液压油变质或混入硬质磨粒、密封件损坏、液压缸本身材料损坏时,它将会迅速出现漏油、自动回缩、动作无力,甚至不能动作等现象,这时必须立即停机检修,否则后果严重。 现以我公司一台TG500E液压式起重机为例,简述变幅液压缸活塞杆的更换过程。 该机右变幅液压缸(装有力矩检测器)漏油严重且活
In the hydraulic construction machinery with a jib, there must be luffing hydraulic cylinder (or boom hydraulic cylinder) to promote the movement of its boom, so that the machinery to meet a variety of operational needs. Although the hydraulic cylinder in the work of huge and complex forces, but as long as the use of the correct, generally not prone to failure. When the hydraulic cylinder is subject to trauma, hydraulic oil deterioration or mixed with hard abrasive particles, the seal is damaged, the cylinder material itself is damaged, it will quickly leak oil, automatic retraction, weakness, or even can not move and so on , Then must be immediately shut down for maintenance, or serious consequences. Take a TG500E hydraulic crane of our company as an example to briefly explain the replacement process of the piston rod of luffing hydraulic cylinder. The aircraft right amplitude hydraulic cylinder (equipped with torque detector) serious and live oil leakage
