High speed high torque hydraulic motor And hydraulic oil pump are the two most critical heat sources in the hydraulic system. The hydraulic motor is an actuator, and the key to the exercise of rotating fitness is the whole process of converting the working pressure energy into mechanical kinetic energy. The hydraulic oil pump is the whole process of converting mechanical kinetic energy into working pressure energy, which is to give all hydraulic systems negative emotions. Today, we are analyzing the problem of hydraulic motor heating. Heating is inevitable in all hydraulic systems, but it is necessary to strictly control the heating condition. To put it bluntly, heat is the loss of kinetic energy, that is, a lot of output power turns into heat immediately after doing nothing. That is to say, under the same working condition standard, the more serious the heating of the hydraulic motor is, the worse the characteristics of the hydraulic motor are, and the general mechanical efficiency is slightly lower. Therefore, when designing the hydraulic motor, we should try our best to ensure that the negative pressure is balanced and the friction resistance of mechanical equipment is small, so that the mechanical efficiency can be improved as much as possible, and it is not easy to make the hydraulic motor overheat seriously. However, the heating of hydraulic motor during the whole operation process is inevitable.

     Cycloidal motor rotor It is very likely that there will be two hot ones, namely, pressure and working speed ratio. Generally, the higher the working pressure and speed ratio, the more serious the heating of the hydraulic motor will be.

Generally, the operating temperature of hydraulic motors should be controlled below 70 ℃ as far as possible. If the temperature is higher, the refrigeration system must be selected. Generally, the refrigeration system has water cooling and air cooling. The actual effect of water cooling and heat dissipation is better. The higher the heating control of the hydraulic system is, the higher the reliability of the hydraulic system is, and the hydraulic system is not easy to have problems.
