The Hongyi water pump of Dongfeng bicycle is broken.

It may be that the water temperature rises and the temperature can't drop.

Symptoms of automobile water pump failure are as follows:

1. The damage of the water pump will weaken the cooling circulation ability or even make it impossible to circulate, and the coolant will "boil".

2. The engine leaks water near the water pump, and the leakage of coolant will leave traces of coolant color on the vent hole of the water pump, leading to symptoms such as excessive water temperature after insufficient coolant.

3. When the engine is working, the abnormal sound of the water pump may be caused by foreign objects inside or bearing wear. Centrifugal water pumps are widely used in automobile engines. Its basic structure consists of water pump shell, connecting disk or pulley, water pump shaft and bearing, water pump impeller and water seal device. It is the main part of a car.

Generally, it is driven by the engine crankshaft through a V-belt. The transmission belt is looped between the crankshaft pulley and the water pump pulley. As soon as the crankshaft rotates, the water pump shaft also operates, and the water pump shaft drives the impeller to rotate, thus realizing the conversion of mechanical energy into hydraulic energy.

Impeller is the core of water pump work, and the movement of impeller itself is very simple, just rotating with the shaft. However, due to the action of blades, the movement of liquid in the impeller is very complicated; On the one hand, it moves with the rotation of the impeller, on the other hand, it is constantly thrown out of the rotating impeller under the drive of the blades, that is, the movement relative to the impeller. Therefore, the outer diameter of the impeller, the height and angle of the impeller blades and the clearance with the pump shell directly affect the performance of the pump.
