Features Of Single-stage Pressure Regulating Circuit Of Four-column Hydraulic Press

The single-stage pressure regulating circuit of the relief valve of the four-column hydraulic press is composed of a quantitative pump, a relief valve, and a hydraulic cylinder, and is the most basic pressure regulating circuit. It has the following characteristics:
The opening pressure of the relief valve can be adjusted by the pressure regulating spring. If the pre-compression of the pressure regulating spring of the relief valve is adjusted, the highest value of the oil supply pressure can be set. The actual working pressure of the hydraulic system is determined by the load.
