Bilens vandpumpe er en af nøglekomponenterne i bilmotorens kølesystem. Dens hovedfunktion er at cirkulere kølervæske og sikre, at motoren holder den korrekte driftstemperatur. Vandpumper til biler består normalt af et leje-understøttet pumpehjul, der drives af motorens krumtapaksel. Når motoren kører, suger pumpehjulet kølevæske fra bilens vandtank og leverer det til forskellige motorkomponenter gennem motorens kølekanaler, mens motoren afkøles og holdes inden for normale driftstemperaturområder. Efterhånden som motorhastigheden stiger, vil vandpumpen øge kølevæskestrømningshastigheden tilsvarende for at tilpasse sig motorens arbejdsbehov.
Bilens vandpumpes design og ydeevne påvirker direkte køleeffektiviteten og motorens samlede ydeevne. Derfor designer og konstruerer producenter ofte omhyggeligt vandpumper for at sikre høj effektivitet, lav støj og lang levetid. Generelt er vandpumper til biler normalt lavet af materialer som støbejern eller aluminiumslegering. Disse materialer har god korrosionsbestandighed og slidstyrke og kan opretholde stabil ydeevne i barske arbejdsmiljøer.

In the field of new energy vehicles, each component plays a vital role. Together, they constitute an efficient and stable operating system for the vehicle. Ningbo Fenda New Energy Technology Co., LTD. focuses on the research and development and production of new energy vehicle components. As the core component of the engine cooling system, the working principle of the car water pump is one of the focuses of our technical exploration and innovation.
In new energy vehicles, the efficient operation of the motor is inseparable from a good cooling system, and the car water pump is a key link in this system. It is responsible for circulating the coolant inside the engine to ensure that the engine temperature is always kept within the optimal working range to avoid performance degradation or even damage caused by overheating. As a professional manufacturer of new energy vehicle components, Ningbo Fenda New Energy Technology Co., LTD. is well aware of the importance of car water pumps and has invested a lot of energy in their design and manufacturing.
1. Basic structure of automobile water pump
The automobile water pump is mainly composed of pump body, impeller, bearing, water seal and gasket. The pump body is the main part of the water pump. Ningbo Fenda New Energy Technology Co., LTD. designed a flow channel inside it to guide the flow of coolant. The impeller is installed in the pump body and connected to the pulley through the bearing. When the engine is running, the pulley drives the impeller to rotate. The bearing is responsible for supporting the rotation of the impeller and bearing the axial and radial forces from the impeller. The water seal and gasket play a key role in preventing coolant leakage.
2. Working principle of automobile water pump
The working principle of automobile water pump can be simply summarized as "rotation drives flow, and pressure difference realizes circulation". Specifically, when the engine starts, the pulley rotates, which in turn drives the water pump bearing and impeller to rotate. During the rotation process, the blades on the impeller suck the coolant from the inlet of the pump body, and it is thrown to the edge of the pump body as the impeller rotates. Due to the centrifugal force, the coolant forms a high-pressure area at the edge of the pump body and flows to various parts of the engine that need cooling through the outlet or water pipe. At the same time, a low-pressure area is formed at the center of the impeller due to the coolant being thrown out. A pressure difference is formed between this low-pressure area and the coolant in the water tank. It is this pressure difference that drives the coolant in the water tank to be sucked into the center of the impeller through the water pipe, thereby realizing the reciprocating circulation of the coolant. In this process, the coolant continuously absorbs heat from the engine and takes it away, and dissipates it into the air through the radiator, thereby ensuring the stability of the engine temperature.
3. Key technologies of automotive water pumps
High-efficiency impeller design: The design of the impeller directly affects the flow and pressure performance of the water pump. Ningbo Fenda New Energy Technology Co., LTD. uses advanced fluid mechanics analysis software to optimize the design of the impeller to ensure that it can generate sufficient centrifugal force to drive the coolant flow and reduce energy loss during rotation.
Precision bearing support: The precision and durability of the bearing are crucial to the running stability of the water pump. Ningbo Fenda New Energy Technology Co., LTD. selects high-quality bearing materials and uses precision processing technology for manufacturing and assembly to ensure that the bearing can remain stable and wear-resistant during high-speed rotation.
Reliable water seals and gaskets: In order to prevent the coolant from leaking into the grease, causing grease emulsification or damaging other components, Ningbo Fenda New Energy Technology Co., LTD. uses high-quality water seals and gaskets for sealing. These seals have good wear resistance and corrosion resistance and can maintain a long-term sealing effect in harsh working environments.
Intelligent temperature control system: With the improvement of the intelligence level of new energy vehicles, Ningbo Fenda New Energy Technology Co., LTD. has also incorporated intelligent temperature control technology into the design of the water pump. Through sensors, the engine temperature and the working status of the water pump are monitored in real time, and the speed and flow of the water pump are intelligently adjusted to ensure that the engine can get the best cooling effect under different working conditions.
4. Maintenance and care of automobile water pumps
Although automobile water pumps have been rigorously tested and verified in design and manufacturing, they still need regular maintenance and care during actual use to ensure their stable and reliable performance. Specifically, it mainly includes the following aspects.
Regularly check the coolant level and quality: Ensuring that the coolant level is within the normal range and the quality is good is one of the important measures to prevent water pump damage. If the coolant is insufficient or deteriorated, it should be replenished or replaced in time.
Cleaning the water pump and cooling system: Regularly cleaning the water pump and cooling system can remove internal impurities and sediments, keep the water flow smooth and improve heat dissipation efficiency.
Check the sealing of the water pump: Regularly checking whether the water seal and gasket of the water pump are intact is one of the key steps to prevent coolant leakage. If the seal is found to be damaged or aged, it should be replaced in time.
Pay attention to driving habits: Good driving habits can also help extend the service life of the water pump. Avoiding long-term high-speed driving or sudden acceleration and deceleration can reduce the load on the engine and the working intensity of the water pump.
