对于工作台长距离的上升或下降,可采用两个单作用的、3级伸缩油缸,要使工作台在上升或下降时保持水平,油缸伸缩时必须同步。使用齿轮马达分流器可保证油缸的同步,另外,不管有没有负载,平台动作的循环时间应保持恒定。在此例子里,平台重1000kg,负载重9000kg。根据经验,我们知道单作用伸缩油缸返回非常慢,特别是在冷天和轻负载下。这个问题的解决就是使返回行程的流量经过齿轮式的流量分配器。
For the long or short distance of the worktable, two single-acting, three-stage telescopic cylinders can be used to keep the workbench horizontal when it is ascended or descended. It must be synchronized when the cylinder is retracted. The use of gear motor splitter to ensure that the cylinder synchronization, in addition, with or without a load, the cycle time of the platform should be kept constant. In this example, the platform weighs 1000kg and weighs 9000kg. As a rule of thumb, we know that single-acting telescopic cylinders return very slowly, especially in cold weather and light loads. The solution to this problem is to make the return travel flow through the gear flow distributor.
