TAD721 BFM1013 V-grooved pulley 04208470 04207054

BFM1013 engine drives the water pump bearing and the impeller to rotate through the pulley, and the coolant in the water pump is driven by the impeller to rotate together, and is thrown to the edge of the water pump shell under the action of centrifugal force,。

Generating a certain pressure at the same time, and then flows out from the water outlet or water pipe.

At the center of the impeller, the pressure is reduced due to the cooling liquid being thrown out. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the action of the pressure difference between the inlet of the pump and the center of the impeller to realize the reciprocating circulation of the cooling liquid.
