Pressure relays for hydraulic pumps

When used for opening and closing the Hydraulic Pump , there are two hydraulic pumps, a high-pressure small-flow pump and a low-pressure large-flow pump. When the piston descends rapidly, the two pumps output pressure oil at the same time. When the piston rod of the Hydraulic cylinder presses against the workpiece, the pressure relay acts under the action of the pressure oil, triggers the micro switch, disconnects the normally closed contact, and stops the Hydraulic pump . Slow down the Hydraulic Cylinder during machining while reducing power consumption.

The pressure relay is a hydraulic electrical conversion element that uses the pressure of the liquid to open and close electrical contacts. When the system pressure reaches the set value of the pressure relay, an electrical signal is sent to make the electrical components (such as electromagnets, motors, time relays, electromagnetic clutches, etc.) act, so that the oil circuit is depressurized and reversed, and the actuators realize sequential actions. Or turn off the motor to stop the system from working for safety protection.

The pressure relay is the element that makes the electric contact act when the fluid pressure reaches the predetermined value in the Hydraulic system. Pressure relay can also be defined as the hydraulic components that convert the pressure into electrical signal. According to the pressure design needs of customers, by adjusting the pressure relay, the function of outputting an electrical signal at a set pressure can be realized.
