液压系统保压回路及其控制

Circuits of Keeping Pressure in Hydraulic Systems and Its Control

液压系统可以采用液控单向阀、蓄能器、液压泵等多种形式实现保压。在现代机床电气系统中,保压回路的控制方式可以通过继电器——接触器控制和可编程控制器PLC实现。

A single - direction valve controlled by liquid, an accumulator and hydraulic pumps can be used to keep pressure in hydraulic systems. In electronic systems of modern machine tool, the control way of circuits of keeping pressure is able to be completed by the relay - toucher and the PLC.
