Everyone knows that the hydraulic gear pump is the heart of the hydraulic system. There must be a pump in the system and an energy conversion device. Its function is to make the flow move and convert mechanical energy into fluid energy. When the pump is used for a long time, the oil temperature will rise too much, so how to deal with the excessive temperature rise of the hydraulic gear pump oil?

1. The oil temperature of the hydraulic gear pump is too high due to the continuous absorption of external heat and the decline in the heat dissipation capacity of the bearing. However, the design requirement is to operate at a constant speed or to use it below the rated voltage, which is not in line with the actual situation; the solution is generally to Take measures in time: for example, choose a constant power pump with a constant flow torque converter to reduce heat generation.
2. The second is to improve the process measures and improve the cleanliness and temperature of the cooling medium to speed up the lubricity of the bearing to reduce the increase in friction.
3. It is also necessary to thoroughly check the mechanical seal and replace the failed oil seal and sealing ring.
4. Install a fan on the output shaft of the system, and use it to inhale air to circulate repeatedly so that the heat source can be transmitted to the outside through the pipeline through the increased pressure, which can achieve the mechanism of rapidly cooling the liquid. We call this method an air-cooled hydraulic gear pump. , Also called cavitation hydraulic pump (the English name for the air-cooled hydraulic pump).
