Information

Reasons

Measures

• The pressure control valve is set too high.
• The safety valve, unloading valve and pressure switch of the unloading circuit are not working properly.
• Improper valve setting of the unloading circuit, short unloading time.
• The valve has many leaks and short unloading time.
• Due to low viscosity or pump failure, increase the internal leakage of the pump, the pump casing temperature rise.
• Insufficient fuel in the tank.
• Inadequate fuel tank construction.
• Over throttling of the remote port of the relief valve, high residual pressure of unloading.
• High resistance of the pipes.

Correct unnecessarily high tuning values and redo the proper tuning.

Correct the various valves that are not working properly.

Change the setpoint correctly.
Repair large leaking valves and consider circuits without large valves.
Change the oil and repair the pump.
Refuel and increase the fuel tank.
Improved structure for even temperature rise around the fuel tank.
Make repairs so that the throttling is not excessive.
Take the appropriate pipe diameter.
