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.
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.
