Impeller pitch explained
Witryna27 lip 2024 · The impeller is a shaft that is powered using an onboard motor. It is coupled to the stator that rotates the blades. To understand the impeller-stator arrangement, it can be likened in principle to the engine of an aeroplane that rapidly increases the outlet velocity of air entering the turbine. WitrynaThe impeller works in the cooling system of the boat. It brings water into the engine to keep it at a cool temperature to not overheat. An impeller has a forward rotation movement, and a propeller rotates clockwise. Besides, an impeller makes water pressure, and a propeller makes water propulsion.
