Tips: What should I do if the hydraulic pump overheats? ​​

There are two reasons for the excessive heating of the hydraulic pump. One is the heat generated by mechanical friction. Since the moving surfaces are in a state of dry friction or semi-dry friction, the moving parts rub against each other to generate heat. The second is heat generation by liquid friction. The high-pressure oil leaks into the low-pressure chamber through various gaps, and a large amount of hydraulic energy is lost to heat energy. Therefore, the correct selection of the clearance between the moving parts, the volume of the fuel tank and the cooler can prevent the overheating of the pump and the overheating of the oil. In addition, the blockage of the oil return filter will cause the oil return back pressure to be too high, which will also cause the oil temperature to be too high and the pump body to overheat.
