Talking about the Problem of Heating of Hydraulic Motor


Hydraulic motors and hydraulic pumps are the two main sources of heat in hydraulic systems. Hydraulic motors are actuators that perform rotary motion and are the process of converting pressure energy into mechanical energy. A hydraulic pump is a process in which mechanical energy is converted into pressure energy, that is, a pressure source for the entire hydraulic system.

   Today, we analyze the problem of the heating of the hydraulic motor. In the entire hydraulic system, heat generation is inevitable, but it is necessary to strictly control the heating situation. As the name suggests, fever is the loss of energy. That is, a lot of power is directly used as a waste of heat. In other words, under the same working conditions, the more severe the hydraulic motor heat, the poorer the performance of the hydraulic motor, the general mechanical efficiency is low. Therefore, when designing the hydraulic motor, static pressure balance and mechanical friction coefficient should be as small as possible, so that the mechanical efficiency can be increased as much as possible, and the hydraulic motor will not generate heat very severely. However, heating of the hydraulic motor during operation is still inevitable.

There are two possible sources of heat for the hydraulic motor: working pressure and operating speed. The higher the pressure and speed, the more severe the hydraulic motor will be.

The working oil temperature of the general hydraulic motor is controlled as low as possible below 70°C. If the oil temperature is too high, a cooling system must be used. Common cooling systems are water-cooled and air-cooled, and the water cooling effect is better. The better the hydraulic system heat control, the better the stability of the hydraulic system and the hydraulic components will not be a problem.
