► Specification

Hydraulic motor is an executive element in the hydraulic system, which can transform the liquid pressure energy provided by the hydraulic pump into mechanical energy, widely used in a number of fields, to understand the relevant knowledge of the hydraulic motor is also vital to do a good job in the maintenance and repair of hydraulic equipment.

Factors affecting the efficiency of hydraulic motors

Hydraulic motor mechanical efficiency and pressure difference, speed related, in the pressure difference is very low, because the friction (mainly cylinder rotation when stirring the hydraulic oil force) consumed by the pressure difference is very large, so the hydraulic motor mechanical efficiency is very low. As the pressure difference increases, the friction force does not change much, but the friction force consumed by the pressure difference accounted for a smaller proportion, so the mechanical efficiency of the hydraulic motor gradually increased; rotational speed is very low, the mechanical efficiency of the hydraulic motor will have a growth trend, because the static friction is greater than the kinetic friction. When the rotational speed reaches a certain level, as the speed increases, the mechanical efficiency of the hydraulic motor will decline, mainly because of kinetic friction (the main cylinder rotating force to stir the hydraulic oil) consumed by the pressure difference between the proportion of the gradual increase. Therefore, hydraulic motors should not be allowed to operate at very low pressure differentials for long periods of time. However, if the motor speed is too low, the pressure difference is large, the volumetric efficiency will fall, and its total efficiency will also be reduced, generally the motor speed control 1000-1800 r/min is more appropriate.
