平移码垛机升降液压回路的改造

IMPROVEMENT OF LIFTING HYDRAULIC CONTROL LOOP OF STACKING MACHINE

针对平移码垛机在生产中出现速度无法控制、设备冲击大、故障率高的问题,分析了产生上述问题的主要原因,在液压控制系统比例阀4WRZE25W8-7X上增加一个单向节流阀Z2FS22-3X/S2,该节流阀的双向流量可以单独调节,解决了上升、下降过程中因负载不同造成的比例阀调节困难问题,设备运行平稳,降低了设备事故率。

The main reasons for the problems of speed beyond control, large impact force, and high failure rate in the production of stacking machine are analyzed. A one - way throttle valve Z2FS22 - 3X/S2 is added in the hydraulic control system proportional valve 4WRZE25W8 - 7X. The bidirectional flow of the throttle valve can be adjusted separately, which solves the problem that the proportional valve is difficult to adjust due to the different load in the process of rising and falling. As a result, the operation of the equipment is stable, and the accident rate of the equipment is reduced.
