提升机是粮食处理中心中必不可少的配套设备之一。为了提高提升机的利用率,达到一机多用的目的,常采用多路阀门。在实际作业中,提升机一般高达数十米,因此多路阀门的控制是个麻烦问题。我们采用了一种比较简单的控制机构,效果较好,现介绍如下。该控制装置的构造见示意图。 Hoist is one of the essential equipment in food processing center. In order to improve the utilization of elevator, to achieve the purpose of a multi-purpose machine, often using multiple valves. In actual operation, hoist generally up to tens of meters, so multi-valve control is a troublesome problem. We use a relatively simple control mechanism, the effect is better, are presented below. The structure of the control device is shown in the schematic.
