Products description

theory
In the cylinder block of the car engine, there are several water channels for the circulation of cooling water, which are 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 tank. water circulatory system. There is a water pump, driven by a fan belt, that pumps hot water into the engine block waterways and draws out 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 the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small circulation) until the engine temperature reaches 95 degrees or above. At start-up, hot water from the engine is pumped into the water tank, and cold air blows through the water tank as the car moves forward, removing heat.
Application of water pump
1. The function of the car is to pump the cooling system to ensure its circulation in the cooling. The popular point is to let the water circulate and blow out the original flavor from the barrel part to ensure that no heat is generated.
2. In the cylinder block of the car engine, there are many water channels for cooling water circulation, which are connected to the front of the car (commonly known as the water tank) through water to form a large water circulation system. , By the way, the water pump, the water pump brought in by the fan, draws out the hot water and cold water in the tank waterway.
3. The water pump has a thermostat. When the car is just started (cold car), it does not turn on, so that the cooling water does not pass through the water tank, and only in the original cycle (called a small cycle) until the temperature of the foreign body reaches 80 degrees. When it is scrapped, it is turned on, and the hot water generated by the engine is pumped into the water tank. When the car is running, the cold air blows through the car, and the water tank passes through the car. It is the predecessor of this book.
4. The water in the car circulates the coolant, the coolant circulates, and the function of the water pump is to pass the transported coolant into the coolant circulation. Car water cooling.

water pump drive

It is usually driven by the engine crankshaft via a V-belt. The drive belt is looped between the crankshaft pulley and the water pump pulley. As soon as the crankshaft rotates, the water pump shaft rotates, and the water pump shaft drives the impeller to rotate, thereby realizing the conversion of mechanical energy to hydraulic energy.
The impeller is the heart of the pump. The movement of the wheel itself is very simple, just rotate with the shaft. However, due to the action of the blades, the movement of the liquid in the impeller is very complicated; on the one hand, it performs a movement related to the rotation of the wheel, and on the other hand, it is continuously thrown out of the rotating wheel under the driving of the blade, that is, it moves relative to the wheel. Therefore, the outer diameter of the impeller, the height and angle of the impeller blades, and the clearance with the pump casing directly affect the performance of the pump.
