Like the hydraulic pump, the hydraulic motor rely on the changes in the sealing work volume to achieve energy conversion, and also has a distribution mechanism. Under the influence of the input high -pressure liquid input, the input liquid cavity has changed from small to large, and torque to the rotor parts to overcome the load resistance torque to achieve rotation; at the same time The fluid oral liquid is reduced, and the pressure is reduced. The high -pressure liquid continuously enters from the inlet of the hydraulic motor and flows out of the liquid mouth, and the rotor of the hydraulic motor continuously rotates and works. Theoretically, except for the hydraulic pump with streaming flow, other forms of hydraulic pumps and hydraulic motors are reversible and can be used in each other. In fact, Shandong Hydraulic Madas told everyone that the same form of pumps and motors in the same form of pumps and motors still have different structurals.
(1) Hydraulic motor is to enter a stressful liquid to push it to rotate, so it must ensure the initial sealing without having to have self -absorbing ability. The hydraulic pump must usually have self -suction ability.
(2) Hydraulic motor should be able to reverse, so its internal structure must be symmetrical. The hydraulic pump is usually rotated unidirectionally, and there is generally no restriction in structure.
(3) The speed range of hydraulic motors is large, especially when the speed is low, it should be able to ensure normal work. Therefore, rolling bearing or static pressure sliding bearing should be used. The speed of the hydraulic pump is higher, and the general changes are small, and there is no such requirement.
