Vane Type Hydraulic Motor
Feb 09, 2018
Because of the pressure oil, the unbalance of force causes the rotor to produce torque. The output torque of the vane type hydraulic motor is related to the pressure difference between the hydraulic motor and the inlet and outlet of the hydraulic motor, and its speed is determined by the flow of the input hydraulic motor. As hydraulic motors are generally required to be able to turn the positive and negative, so blade-type hydraulic motor blades to be placed radially. In order to make the blade root always through the pressure oil, in the back, pressure oil cavity through the path of the root of the blade should be set one-way valve, in order to ensure that the blade-type hydraulic motor in the pressure oil after the normal start, must make the blade top and the stator inside the surface close contact to ensure good sealing, so in the blade root should be set preload spring. The vane type hydraulic motor is small in size, small in moment of inertia, sensitive in motion and suitable for occasions with high commutation frequency, but the leakage is large and unstable at low speed. Therefore, vane-type hydraulic motors are generally used for high speed, small torque and sensitive action requirements.
