A car electric cooling pump is simply a water pump: a power mechanism that circulates the car's antifreeze from the engine to the water tank. The water pump is broken, the antifreeze is not circulating, the engine needs to be run, and the water temperature is too high, which may affect the engine cylinder.
The role of automobile cooling water pump
The car water pump is also called the car electric coolant pump. The key of the car water pump is the key component of the forced circulation of the car cooling system. The engine pulley drives the bearing and the impeller of the water pump to run, and the antifreeze in the water pump is driven by the impeller to rotate, and is thrown to the edge of the water pump shell under the action of centrifugal force, and at the same time causes the necessary pressure, and then flows out from the water outlet or water pipe. As the antifreeze is thrown out, the pressure in the center of the impeller drops, and the antifreeze in the water tank is sucked into the impeller through the water pipe under the pressure difference between the inlet of the pump and the center of the impeller to realize the reciprocating circulation of the antifreeze.
When the car is driving, add antifreeze every 56,000 kilometers, and it will be added 2 or 3 times in a row, and it will be replaced by suspecting that there is a leak. Since the engine is hot, it will wipe the water away. Under normal circumstances, it is difficult to detect the leakage of the water pump at the beginning, but it is possible to carefully detect whether there is water stains under the pump. Under normal circumstances, the service life of the car water pump can be about 200,000 kilometers.
There is a water channel for cooling water circulation in the cylinder of the car engine, which is connected to the radiator (commonly known as the water tank) placed in the front of the car through the water pipe to form a large water circulation system. At the upper water outlet of the engine, a water pump is installed, driven by a fan belt, to pump out the hot water in the water channel of the engine cylinder, and pump in the cold water. There is also 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 only circulates in the engine without passing through the water tank (commonly known as small circulation). When the engine temperature reaches above 80 degrees, it is turned on, and the hot water in the engine is pumped into the water tank. When the car moves forward, the cold air blows through the water tank to take away the heat, which basically works like this.
Simply put, it's the water pump: the power mechanism that circulates the car's antifreeze from the engine to the water tank. The water pump is broken, the antifreeze does not circulate, the engine needs to be run, and the water temperature is too high, which may affect the engine cylinder, which is troublesome. Therefore, it is best for drivers to have the habit of observing the car's instrument while driving, just as carefully as how much gasoline is left.
