The same number of blades weld on the radial direction of pump impeller and turbine to transmit power After pump impeller and turbine assembled,the vertical section through the input shaft or output shaft is a ring,which is called torus section.The liquid to transfer power is driven by pump impeller's blade and does rotary motion around the axis.The liquid flows to the blade tip and it's speed increases under the action of the centrifugal force.The speed depends on the speed of the crankshaft and the radius of working wheel.The kinetic energy of the liquid increases after pressure rising by hit the wall', and rushes at turbine's blade to drive turbine rotating Afterwards,the kinetic energy of the liquid decreases and a dynamic fluid circulation from the high energy region to the low energy region forms.That is liquid rushes from the outer edge of pump impeller to turbine and forms a end- to-end spiral
The same number of blades weld on the radial direction of pump impeller and turbine to transmit power . After pump impeller and turbine assembled, the vertical section through the input shaft or output shaft is a ring, which is called torus section. The liquid to transfer power is driven by pump impeller’s blade and does rotary motion around the axis. The liquid flows to the blade tip and it’s speed increases under the action of the centrifugal force. The speed depends on the speed of the crankshaft and the radius of working wheel. The kinetic energy of the liquid increases after pressure rising by ‘hit the wall’, and rushes at turbine’s blade to drive turbine rotating . Afterwards, the kinetic energy of the liquid decreases and a dynamic fluid circulation from the high energy region to the low energy region forms. That is liquid rushes from the outer edge of pump impeller to turbine and forms a endto-end spiral
Conclusion: The working process of hydraulic coupler Pump impeller receives the mechanical energy from the engine and transfers it to the working fluid,so the kinetic energy of working fluid increases.Then the kinetic energy of working fluid transfers to the turbine to realize the power output. The necessary conditions of hydraulic coupler to realize transmission: There is a liquid circulation flow between pump impeller and turbine, the reason why there is a liquid circulation flow is that existing speeds difference between the two.So pump impeller's speed is always higher than turbine's when hydraulic coupler is working. The working principle of hydraulic coupler When the kinetic energy of flowing liquid changes,it will absorb or release energy
