针对液压捣固机使用过程中经常出现夹实液压缸一快一慢的现象,分析其原因是由于强烈振动引起活塞与活塞杆之间的圆螺母松动,液压油外泄,系统压力降低所致。在不影响活塞强度的情况下,在活塞内圈上车出一定宽度的沟槽,加O形密封圈密封,可有效解决液压油外泄的问题,提高捣固机的作业效率。
Aiming at the phenomenon that the hydraulic cylinder tamping cylinder often appears fast and slow during the use of the hydraulic tamping machine, the reason is that due to the strong vibration, the round nut between the piston and the piston rod is loosened, the hydraulic oil leaks and the system pressure is reduced . Without affecting the strength of the piston, the piston inner race car out a certain width of the groove, plus O-ring seal, which can effectively solve the problem of hydraulic oil leakage and improve the efficiency of tamping machine.
