Products Description
The working principle and composition of the relief valve of the pump truck
The relief valve of the pump truck is a hydraulic control type pressure regulator, which controls the pressure and flow of the system by adjusting the opening of the relief valve port to achieve the effect of protecting the system, realizing braking, preventing the overload of the hydraulic system, eliminating the peak pressure of the hydraulic system, etc. The relief valve of the pump car is composed of the valve body, the adjusting element in the valve, the relief valve core, the pressure relief unloading valve and the pressure relief valve core.
Second, the role of the relief valve of the pump car
1. Control the pressure and flow of the hydraulic system: when the pressure in the hydraulic system reaches the set value, the relief valve of the pump car will automatically open to limit the pressure in the hydraulic system and protect the system from overload or overpressure damage.
2. Prevent the peak pressure of the hydraulic system: When the movement of the actuator is over, the relief valve of the pump car can also be opened by opening the relief valve port to rapidly reduce the pressure in the hydraulic system, avoid the peak pressure caused by inertia and other factors, and protect the hydraulic system from damage.
3. Realize braking and unloading: In the emergency or shutdown state, the relief valve of the pump car can play the role of braking or unloading, and quickly reduce the pressure in the hydraulic system to achieve the stability of the frame and the rapid unloading of the actuator.
4. Adjust the flow of the system: the relief valve of the pump car can also adjust the hydraulic flow in the system by changing the opening of the valve port to meet the needs of different working states.
