Information

The function of the expansion tank of the car is to discharge the gas in the cooling system, and to supply antifreeze to the cooling system accordingly. By increasing the pressure of the cooling system to increase the pressure of the water pump, it is also to avoid the damage caused by the cavitation of the water pump.

The key to the flow of antifreeze is the pressure of the water pump. When the pressure of the water pump is very low, steam bubbles will be formed, and the water volume will decrease at this time. But it is easy to cause cavitation. At this time, there will be pits on the surface. If this problem is not avoided, the service life will be shortened directly.
The flow of steam bubbles in the radiator enters through the conduit, so that the steam and water will be completely separated. The temperature of the expanded water is mostly quite low, allowing the gas to get the necessary cooling, and then enter the pump from the new one for continued use. Let the corresponding gas cause its buffer effect, then the pressure of the cooling system will be maintained at a normal state.
