Principle:

The variable speed fluid couplings is a power-delivering equipment with liquid, the drive machine revolve the pump, under the action of the centrifugal force, the liquid driving by the pump blade move to top of the blade from root and form high-pressure and super-speed liquid and rush at the turbine blade and make the turbine follow the pump to round as the same direction, the liquid move to root of the turbine blade from top and get deceleration and decompression then go into the pump, the liquid continue to circle as the mode, the pump transform machine energy of the drive machine into kinetic energy and potential energy of the liquid, then the turbine transform kinetic energy and potential energy of the liquid into machine energy of the export shaft, energy-delivering has been gotten. Regulating the speed of working-machine steplessly and keeping the speed of the drive machine constant can be realized just change the amount of the liquid in the working-chamber.

Function:
Regulating speed steplessly;
No-load or light-load to start the heavy carry;
Insulating twist vibration;
Over-load protection;
The high-efficiency delivering power ;
Apt to get automatic control.

Use:
All kinds of water pump and fan, which need change load to run, can choose the variable speed fluid couplings to get regulating speed steplessly and energy-saving. Our product have extensive been used in the metallurgy, the mine, the chemical engineering, the petroleum, the power plant, the cement, the municipal feed-water and feed-vapor, the light-industry, the spin and weave and so on. It is an energy- saving product recommended stress by government.

Constant Filling Fluid Coupling
