Industrial Hydraulic Motor

Product Detail

Industrial hydraulic motor




The hydraulic motor is an actuator of the hydraulic system, which converts the liquid pressure provided by the hydraulic pump into the mechanical energy (torque and rotational speed) of its output shaft. Liquid is the medium of transfer and motion.

Hydraulic motor, also called oil motor, mainly used in injection molding machinery, ships, Yang machine, engineering machinery, construction machinery, coal machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, port machinery, etc.




Feature

From the point of view of energy conversion, hydraulic pump and hydraulic motor are reversible working hydraulic components, which can be converted into hydraulic motor condition by entering the working liquid to any type of hydraulic pump. Conversely, when the main shaft of the hydraulic motor is driven by external torques, it can also be turned into hydraulic pump condition. Because they have the same basic structural elements - the closed and periodic change of volume and the corresponding oil distribution mechanism. However, due to different working conditions of hydraulic motor and hydraulic pump, the performance requirements are different, so there are still many differences between the same type of hydraulic motor and hydraulic pump. First, the hydraulic motor should be able to be positive and reverse, thus requiring its internal symmetry; The speed range of the hydraulic motor needs to be large enough, especially for its minimum stable speed. Therefore, it usually adopts rolling bearing or static sliding bearing; Secondly, the hydraulic motor can work under the input pressure oil conditions, so it doesn't have to have the self-absorption ability, but it needs some initial sealing ability to provide the necessary starting torque. Because of these differences, the hydraulic motor and hydraulic pump are similar in structure, but cannot be reversible.
