The role of car water pump

  • The role of the automobile water pump is to pressurize the coolant to ensure that it circulates in the cooling system. In layman's terms, it continuously circulates the water through the radiator and the engine block. Take away the heat. . Ensure that the engine is not hot.
  • In the cylinder block of a car engine, there is a water channel for the circulation of cooling water, which is connected to the radiator (commonly known as the water tank) placed at the front of the car through a water pipe to form a large water circulation system. There is a water pump, driven by the fan belt, to pump out the hot water in the engine block waterway, and pump in the cold water.
  • There is a thermostat next to the water pump. When the car is just started (cold car), it is not turned on, so that the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as the small cycle), until the temperature of the engine reaches 80 degrees or more. When the engine is turned on, the hot water in the engine is pumped into the water tank, and the cold wind when the car is moving forward blows through the water tank and takes away heat. This is roughly how it works.
  • The automobile water pump is used to drive the coolant circulation. The engine can cool down only when the coolant circulates.
  • The function of the water pump is to pressurize the coolant flowing through the radiator and send it into the water jacket of the cylinder to facilitate the flow of cooling water! The principle is to use the centrifugal force generated by the impeller to pressurize the water and send it out.

Gasoline engine water pump maintenance

  • The editor talks about the knowledge of gasoline engine water pump maintenance
  • Early car engines did not have an important accessory that we think is indispensable today-water pump. The liquid cooling medium used at that time was pure water, mixed with wood alcohol at most to prevent freezing. The circulation of cooling water completely relies on the natural phenomenon of heat convection. After the cooling water absorbs heat from the cylinder block, it naturally flows upward and enters the upper part of the radiator; after the cooling water becomes cold, it naturally sinks to the bottom of the radiator and enters the lower part of the cylinder block.
  • Using this thermosyphon principle can barely complete the cooling task. But soon after, a water pump was added to the cooling system to allow the cooling water to flow more quickly.
  • The cooling system of modern automobile engines generally uses centrifugal water pumps. The reasonable installation location of the water pump is at the bottom of the cooling system, but most of the water pumps are placed in the middle of the cooling system, and a few water pumps are placed on the top of the engine. The water pump placed on the top of the engine is prone to cavitation. No matter where it is, the pumping capacity of the water pump is very large. For example, the pumping capacity of a V8 engine is about 750L/h at idling speed and about 12000L/h at high speed.
  • In terms of service life, the biggest change in water pump design is the appearance of ceramic seals a few years ago. Compared with the rubber seals or leather seals used before, ceramic seals are more wear-resistant, but they also have easy The disadvantage of being scratched by hard particles in the cooling water. Although continuous improvements have been made in the design to prevent the failure of the water pump seal, it has not been possible to guarantee that the water pump seal will not have problems so far. Once the seal leaks, the lubrication of the water pump bearing will be washed away.
