Function of the water pump: The function of the automobile water pump is to pressurize the coolant and ensure its circulation in the coolant. Generally speaking, water is continuously circulated through various components of the radiator engine block to take away heat and ensure that the engine does not become too hot. How the pump works: The engine drives the pump bearing and impeller to rotate through a pulley. The coolant in the pump is driven by the impeller and is thrown to the edge of the pump casing under the action of centrifugal force, generating a certain pressure, and then flows out from the outlet or water pipe. As the coolant is thrown out, the pressure in the center of the impeller decreases. Under the pressure difference between the water pump inlet and the center of the impeller, the coolant in the water tank is sucked into the impeller to realize reciprocating circulation of the coolant.
The key to the car water pump is the key component of the forced circulation of the car cooling system. The engine pulley drives the pump's bearings and impeller. The antifreeze in the pump is driven by the impeller to rotate, and is thrown to the edge of the pump casing under the action of centrifugal force, causing necessary pressure, and then flows out from the outlet or water pipe. As the antifreeze is thrown out, the pressure at the center of the impeller is reduced, and the antifreeze in the water tank is sucked into the impeller through the water pipe. The antifreeze circulates back and forth under the pressure difference between the pump inlet and the center of the impeller.
There is a water channel for cooling water circulation in the automobile engine cylinder, 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. The water pump is installed at the upper outlet of the engine and is driven by the fan belt to extract hot water from the engine cylinder water channel and pump cold water in. There is also a thermostat next to the water pump. When the car is just started (cold), the cooling water only circulates within the engine and does not pass 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, cold air blows through the water tank and takes away the heat.
Simply put, it is the power mechanism of the water pump that circulates car antifreeze from the engine to the water tank. The water pump is broken and the antifreeze is not circulating, requiring the engine to run. Excessively high water temperature may affect the engine cylinder and cause trouble. Therefore, it is best for drivers to observe the habit of car instruments when driving, just like how much gasoline is left.
1. Cooling system antifreeze: (1) Radiator leaks from cracks or holes. The cylinder water jacket is damaged, resulting in loss of cooling water. (2) The inlet and outlet pipes are damaged and leaking. (3) The switch is damaged and leaking.
Maintenance methods: (1) Use anti-leak agent to plug leaks. If the leakage is severe, the radiator should be replaced. (2) If the water pipe is broken and aged, replace it with a new one. (3) If the switch is damaged and antifreeze leaks, replace the switch.
2. The engine antifreeze temperature is too high. Reasons: (1) Insufficient cooling water. (2) If the fan drive belt is broken or over-adjusted, the cooling effect disappears or weakens. (3) There is a lot of scaling on the cylinder water jacket and radiator, and the heat dissipation performance decreases. (4) The pump operates abnormally and the water circulation is not smooth. (5) Pour the radiator or connect the hose to exhaust. (6) Water temperature meter and sensor failure.
Troubleshooting methods: (1) Add cooling water immediately. If the radiator is leaking, it should be repaired. (2) Adjust the tightness of the fan drive belt or replace it with a new one. (3) Clean the cooling system to remove scale. (4) Repair or replace the pump. (5) Check the water outlet pipe, eliminate shrinkage, and repair the radiator. (6) Repair or replace the water temperature meter and sensor.
Although gasoline engines have been extensively improved, they are still very inefficient in the process of converting chemical energy into mechanical energy. The job of a car's cooling system is to convert most of the energy in gasoline (about 70%) into heat. In fact, the cooling system of a car traveling on the highway loses enough heat to heat two average houses! Will add if the engine gets cold.
1. Engine overheating
Bubbles: The gas in the air cooling liquid will produce a large number of bubbles under the stirring of the pump, which hinders the heat dissipation of the water jacket wall.
Scale: The calcium and magnesium ions in the water will gradually develop into scale after high temperature is required, which will greatly reduce the heat dissipation capacity. At the same time, waterways and pipes are partially blocked, and the coolant cannot flow normally.
Harm: The engine parts heat and expand, destroying the normal fitting clearance, affecting the cylinder air volume, reducing power, and reducing the lubrication effect of the engine oil.
2. Corrosion and leakage
It is highly corrosive to ethylene glycol water tanks. Components such as radiators, water jackets, water pumps, pipes, etc. corrode as anti-power fluid corrosion inhibitors fail.
liquid cooling
The cooling system of a liquid-cooled car circulates fluid through pipes and channels in the engine. As fluid flows through a hot engine, it absorbs heat, lowering the engine's temperature. After the liquid flows through the engine, it turns to the heat exchanger (or radiator), and the heat in the liquid is dissipated into the air through the heat exchanger. Some early cars used air cooling technology, but it is rarely used in modern cars. Instead of circulating fluid through the engine, this cooling method cools the cylinders through aluminum flakes attached to the surface of the engine cylinders. A powerful fan blows air towards these aluminum sheets, dissipating heat into the air to cool the engine. Since most cars use liquid cooling, this article will focus on liquid cooling systems. There are a lot of pipes in your car's cooling system. Check the entire system one at a time from the pump. In the next section we will patiently explain the components of the system. After the pump delivers the fluid to the engine block, the fluid begins flowing in the engine passages surrounding the cylinder.
