What problems can affect the service life of the pump

1. Coolant leakage, which accelerates the aging process of the pump seal.

2. If the engine's combination belt is adjusted too tightly, it may cause premature wear of the water pump.

3. Problems can also occur if the pump is not replaced for a long time after reaching the end of its expected service life.

4. The shaft of the automobile water pump is bent, the shaft journal is worn, or the shaft end thread is damaged.

5. The blades on the impeller of the pump are chipped, or the shaft load hole is worn.

6. Wear and tear of water seals and bakelite gaskets due to long-term use.

7. Poor working condition of the pump may lead to poor circulation system, which may lead to high temperature, which may cause problems such as pump leakage or broken blades, which will further affect the normal operation of the circulation system.

8. If the antifreeze is not replaced for a long time, the corrosive effect inside it may eventually lead to damage to the water pump.

Water Pump Driven

Generally, the crankshaft of the engine is driven by a V-belt. The transmission belt is surrounded between the crankshaft pulley and the water pump pulley, and the water pump shaft will follow the operation of the crankshaft as soon as it rotates, and the water pump shaft will drive the impeller to rotate, so as to realize the conversion of mechanical energy into hydraulic energy.The impeller is the core of the pump's work, and the movement of the impeller itself is simple, just rotating with the shaft. But due to the action of the blades, the movement of the liquid in the impeller is complex; On the one hand, it is implicated with the rotation of the impeller, and on the other hand, it is continuously thrown out of the rotating impeller under the drive of the blades, that is, the movement of the relative impeller. Therefore, the outer diameter of the impeller, the height and angle of the impeller blades, and the clearance between the impeller blades and the pump housing directly affect the performance of the pump
