hydraulic coupling of the pump wheel and turbine

Fluid coupling finite rectangular and variable speed fluid coupling, the following is its knowledge of the pump wheel and turbine .
Fluid coupling the pump wheel and turbine components of a liquid can flow in a closed working chamber circulation pump wheel mounted on the input shaft , a turbine mounted on the output shaft Jic hydraulic fittings the power machine ( engine , electric motor , etc. ) to drive the input shaft rotation , the liquid thrown by centrifugal pump wheel , after this high-speed fluid into the turbine rotates a turbine , the energy obtained from the pump wheel to the output shaft , and finally the liquid return pump wheel , the flow of the formation cycle .
Fluid coupling by the liquid and the pump wheel , the momentum generated by the interaction of the turbine blade to transfer the torque moment changes , its output torque equal to the input torque minus the friction torque, so that its output torque is less than the input torque of the torque constant , coupling between the input shaft and the output shaft by liquid contact , working member rigid connection does not exist between
