31. Hydraulic equipment

Principle of Hydraulic transmission

1- Centrifugal pump          5- Return line

2- Hydraulic turbine          6- Tank

3- Hydraulic line                7- Suction pipe

4-Nozzle

Application

-Clutch and unclutch crankshaft of the main engine and the propeller shaft.

-Extend working region of the propulsion plant. The main engine will not be overloaded in rough sea conditions.

-It permits a centering error between the crankshaft and the propeller shaft.

-Reversible hydraulic driving equipment can be used.

-Hydraulic-driving equipment is applied in the propulsion plant as a hydraulic clutch or a hydraulic speed reducer.
