Hydraulic transmission works:

(1) The prime mover drives the centrifugal pump to rotate, sucks the liquid through the inlet pipe, and is accelerated in the centrifugal pump to obtain kinetic energy.
(2) The isokinetic liquid with a certain kinetic energy from the centrifugal pump enters the turbine through the conduit, impacts its blades to rotate the turbine, and outputs a rotary motion through the turbine shaft.
(3) The speed of the liquid discharged from the turbine is reduced and the kinetic energy is reduced.
