Water pump drive
It is generally driven by the V-belt of the crankshaft of the engine. The drive belt is surrounded by the crankshaft pulley and the water pump pulley. The crankshaft and the water pump shaft also follow the operation, and the water pump shaft drives the impeller to rotate, thereby converting mechanical energy into hydraulic energy.
The impeller is the core of the pump's work. The movement of the impeller itself is very simple, just rotating with the shaft. However, due to the action of the blades, the movement of the liquid in the impeller is very complicated; on the one hand, the impeller is rotated to make an impending motion, and on the other hand, under the driving of the blades, the impeller is continuously pulled out from the rotating impeller, that is, relative to the impeller. Therefore, the outer diameter of the impeller, the height and angle of the impeller blades, and the gap with the pump casing directly affect the performance of the pump.
