在直流电液控制系统中,集中控制电磁阀的方式通常有两种:一种采用万能转换开关控制;另一种是用按钮开关通过中间继电器来控制。采用第一种方法,必须先按系统工作状态和电磁阀线圈通断情况编排表格,然后根据这一表格选择满足系统工作要求的万能转换开关。这种方法有时很费事,甚至难以找到满足要求的万能转换开关。第二种方法与第一种相比,操作不便,维护比较麻烦,可靠性也较低。本文介绍的一种方法,是利用硅整流二极
In the DC electro-hydraulic control system, there are usually two ways to control the solenoid valve in a centralized manner: one is controlled by a universal change-over switch; the other is controlled by a push-button switch through an intermediate relay. The first method, you must first press the working state of the system and solenoid valve on-off layout of the table, and then select the form according to the table to meet the system requirements of universal conversion switch. This method is sometimes cumbersome, even difficult to find to meet the requirements of the universal transfer switch. The second method compared with the first, inconvenient to operate, maintenance is too much trouble, reliability is also low. One method described in this article is to use a silicon rectifier diode
