Elimination method of high oil temperature in hydraulic power station

1 ► Set the pressure too high Adjust the pressure properly

2 ► The components of the relief valve, unloading valve, pressure relay and other unloading circuit are not working properly

3 ► The element setting value of the unloading circuit is not appropriate, and the unloading pressure is re-set in a short time to extend the unloading time

4 ► Large leakage of valve, short unloading time repair large leakage valve, consider not using large specifications valve

5 ► When high pressure small flow, low pressure large flow, do not change the circuit by the overflow valve, use the unloading valve, variable pump

6 ► Due to low viscosity or pump failure, the internal leakage of the pump is increased, and the temperature of the pump shell is increased

7 ► The oil in the tank is insufficient to refuel, increase the oil tank

8 ► Unreasonable tank structure Improve the structure and make the temperature around the tank rise evenly

9 ► Accumulator capacity is insufficient or faulty Change the accumulator, repair the accumulator

10 ► Need to install the cooler, the cooler capacity is insufficient, the cooler is faulty, the inlet valve is not working properly, the amount is insufficient, the oil temperature automatic regulation device is faulty Install the cooler, increase the cooler, repair the fault of the cooler, repair the valve, increase the water volume, repair the temperature control device

11 ► Excess throttling of the remote control port of the relief valve, the remaining pressure of unloading should be adjusted appropriately

12 ► Suitable pipe diameter for high pipe resistance

13 ► The influence of nearby heat sources, the use of thermal insulation material reflection panels or change the layout; Set up ventilation, cooling devices, etc., select the appropriate working fluid
