We often encounter overheating of hydraulic pumps in our daily life. There are two reasons for overheating. One is the heat generated by mechanical friction.  As the moving surfaces are in a dry friction or semi-dry friction state, the moving parts rub against each other to generate heat.  Second, liquid friction generates heat.  High pressure oil leaks into the low pressure chamber through various gaps, and a large amount of hydraulic energy is lost and converted into heat energy.  Therefore, the correct choice of the clearance between moving parts, the volume of the oil tank and the cooler can prevent the excessive heating of the pump and the excessive oil temperature.  In addition, the blockage of the oil return filter will cause high oil return back pressure, which will also cause high oil temperature and overheating of the pump body.
