Installed the blade of radial vane hydraulic motors

Due to the pressure oil, unbalanced force make the rotor torque is produced. Vane hydraulic motor output torque and displacement of hydraulic motor and hydraulic motor oil in and out of the mouth, the pressure difference between the speed determined by the input to the flow of hydraulic motor size.
Due to the hydraulic motor to generally positive &negative, so vane hydraulic motor blade radial placed. In order to make the blade root pressure on oil, always in the back, pressure oil cavity ordinary check valve shall be set up on the path of blade root, in order to ensure the vane hydraulic motor can normal boot after pressure oil factory, must make the top and the stator blade surface close contact, to ensure a good seal, therefore the preloaded spring shall be set up at the blade root.
Vane hydraulic motor is small in size, moment of inertia of small, action quick, can be applied to the reversing frequency occasions, but leakage is larger, while working at low speed is not stable. So vane hydraulic motor is generally used in high speed, small torque and motion sensitivity required.
