Auto water pump flange generally has the function of self-priming. Self-priming means that when the water pump of the water pump is filled with air, the negative pressure (vacuum) formed when the water pump is working will be lower than the water pressure of other water outlets under the action of atmospheric pressure. up and out the drain end of the pump. Before this process, there is no need to add "water lead (water guide)". The micropump with this self-priming ability is called "micro self-priming pump", and the principle is similar to that of a micro air pump.

The electronic water pump for automobiles combines the advantages of self-priming pumps and chemical pumps. It can be made of a variety of corrosion-resistant imported product materials, with acid resistance, alkali resistance, corrosion resistance and other properties; the suction lift is as high as 5 meters, and there is basically no noise. Exquisite workmanship, not only has the function of self-priming, but also has large flow (up to 25 liters/min), high pressure (up to 2.7 kg), stable performance and easy installation. Therefore, this large flow control water pump is often used in the development of new energy vehicles.
The engine can drive my country's automobile electronic water pump, bearings and impeller to rotate through the pulley. The coolant in the automobile control water pump rotates together under the driving of the impeller, and is thrown to the edge of the automobile water pump shell under the action of centrifugal force. At the same time, it can generate a certain pressure, and then flow out from the water outlet or water pipe as well. outflow. At the center of the impeller, the coolant is thrown out and the pressure is reduced. The cooling liquid in the water tank is sucked into the impeller by the water pipe under the action of the pressure difference between the inlet of the automobile electronic water pump and the development of the impeller center to realize the reciprocating circulation of the cooling liquid in the system.
The bearing supporting the shaft of the Auto water pump flange is lubricated with grease, so it is necessary to prevent the oil from penetrating into the grease and cause the grease to emulsify, and also to prevent the grease from leaking out. The sealing technical measures of the Auto water pump flange to prevent information leakage mainly include water seals and gaskets. The water seal dynamic seal ring and the shaft are installed between the impeller and the bearing through interference fit, and the water seal static seal seat is pressed on the Auto water pump flange shell to achieve sealing cooling.
The Auto water pump flange housing can be connected with the engine through gaskets and support moving functional parts such as bearings. There is also a drain hole on the Auto water pump flange housing, which is located between the water seal and the bearing. Once it is found that the coolant can leak through the establishment of the water seal, it can leak from the drain hole to prevent the coolant from entering the Chinese bearing cavity and destroy the bearing lubrication and cause a part to rust. If the engine is stopped and the coolant is still leaking, the water seal will be damaged.
The operation process of Auto water pump flange:
1. Centrifugal water pumps are widely used in automobile engines. Its basic economic structure is mainly composed of the water pump through the casing, the connecting plate or the pulley, the water pump shaft and the bearing or the connecting shaft bearing, the water pump impeller and the water sealing technology device, etc. It is the main working part of the automobile.
2. The bearing supporting the water pump shaft of the system is lubricated with grease, so it is necessary to prevent the oil and emulsification caused by the leakage of the coolant into the grease, and prevent the grease from leaking. The sealing technical measures of the Auto water pump flange to prevent information leakage mainly include water seals and gaskets. The dynamic seal ring and shaft of the water seal are set between the impeller and the bearing through interference fit, and the static seal seat of the water seal is pressed on the pump casing to achieve the purpose of sealing the pump casing. coolant.
3. The car electronic water pump shell is connected to the engine through a gasket, and supports moving functional components such as bearings. There is also a drain hole in the pump housing, located between the water seal and the bearing. Once it is found that the coolant can leak through the establishment of the water seal, it can leak from the drain hole to prevent the coolant from entering the Chinese bearing cavity and destroy the bearing lubrication and cause a part to rust. Auto water pump flange manufacturers tell you that if the engine stops and the coolant still leaks, the water seal will be damaged.
