Product Details

Hydraulic coupler is a hydraulic transmission device, ignoring mechanical losses, output torque and input torque equivalent hydraulic elements.

It consists of two working wheels, the pump wheel and the turbine, which are the basic components of energy conversion and power transmission. The pump wheel and the turbine have the same inner and outer diameter and are equipped with the blades with radial arrangement.

When the pump wheel and turbine are installed relative to each other, about 3-4mm clearance is left between the two end surfaces.

The pump wheel is integrated with the turbine, and its axial section is generally circular, with working oil in its inner cavity.


When the hydraulic coupling works, the power of the engine passes to the pump wheel through the input shaft, and drives the pump wheel to rotate at the speed.

Due to the action of the pump wheel blade, the working oil in the coupling rotates along the axis along with the blade.

Under the action of centrifugal force, the oil flows along the channel between blades from a small radius to a large radius.

At this point, the kinetic energy and pressure energy of the oil at the outer edge of the blade are both greater than the kinetic energy and pressure energy of the oil at the inner edge of the blade.

By the action of the pump wheel blade, the oil will leave the pump wheel when it reaches the outer edge of the blade, which has become a high-speed liquid flow with certain pressure and speed, realizing the energy of transforming the engine's mechanical energy into working oil.
