The engine water pump is an important part of the automobile engine cooling system. Its main function is to reduce the engine temperature by circulating coolant to ensure that the engine runs at a normal temperature. The following is a detailed introduction to the engine water pump:

1. Structure and working principle

The engine water pump is usually composed of a water pump housing, a connecting plate or a pulley, a water pump shaft and bearings or a shaft-to-bearing, a water pump impeller, a water seal device, etc. Its working principle is that the engine drives the water pump bearing and impeller to rotate through the pulley, and the coolant is driven by the impeller to rotate together. Under the action of centrifugal force, it is thrown to the edge of the water pump housing, and a certain pressure is generated at the same time, and then it flows out from the outlet or water pipe to achieve pressurization and circulation of the coolant.

2. Function and effect

In the cylinder of the car engine, there are multiple water channels for cooling water circulation, which are connected to the radiator (commonly known as the water tank) at the front of the car through water pipes to form a large water circulation system. The engine water pump is located at the upper water outlet of the engine and is driven by a fan belt. Its main function is to pump out the hot water in the water channel of the engine cylinder and pump in cold water at the same time, so as to ensure that the engine always works within the appropriate temperature range.

3. Maintenance and Inspection

To ensure the normal operation of the engine water pump, it needs to be maintained and inspected regularly. Specifically:

1. Check the pump body and pulley for wear and damage and replace if necessary.
2. Check whether the water pump shaft is bent, the journal is worn, and the shaft end thread is damaged.
3. Check the wear degree of the water seal and bakelite gasket. If it exceeds the usage limit, replace it with a new one.
4. Check the bearing wear. If the clearance is too large, replace the bearing with a new one.

In addition, during the inspection process, you also need to pay attention to whether the water pump bearing rotates flexibly and whether there is any abnormal noise. If there is any abnormality, it should be dealt with in time.

In short, the engine water pump is an indispensable part of the automobile engine cooling system, and its normal operation is of great significance to ensure the performance and life of the engine. Therefore, car owners should regularly maintain and inspect the engine water pump to ensure that it is in good working condition.
