Function:

The role of the crane relief valve is mainly in the following aspects:
1. Constant pressure relief: in the quantitative pump throttling adjustment system, the quantitative pump provides a constant flow. When the system pressure increases, it will make the flow demand decrease, at this time the relief valve opens, so that the excess flow overflow back to the tank, to ensure that the relief valve inlet pressure, that is, the pump outlet pressure is constant.
2. Pressure stabilising effect: the relief valve is connected in series on the return line, the relief valve generates back pressure, and the smoothness of the moving parts increases.
3. system unloading: the remote port of the relief valve is connected in series with a small flow relief solenoid valve, when the solenoid is energised, the remote port of the relief valve through the tank, this time the hydraulic pump unloading. The relief valve is used as an unloading valve at this time.
4. safety protection: the system works normally, the valve is closed. Only when the load exceeds the specified limit (system pressure exceeds the regulated pressure) the relief is opened for overload protection so that the system pressure does not increase. Normally, the regulating pressure of the relief valve is 10% to 20% higher than the maximum working pressure of the system.
In summary, the crane relief valve in the crane hydraulic system plays a vital role, can ensure the stable operation of the system and the safety of the equipment.
