Brief introduction of several electronic water pumps for new energy vehicles
Electronic water pumps for automobiles, new energy vehicles, recreational vehicles and many other special vehicles are often used as micro-pumps for automobile water circulation, cooling or water supply systems. This kind of miniature self-priming water pump is collectively called automobile water pump. The circular motion of the motor makes the diaphragm in the water pump reciprocate through the mechanical device, so the air in the pump cavity (constant volume) will be compressed and stretched, and under the action of the one-way valve, it will become positive pressure at the water outlet (the actual output pressure is related to the auxiliary power at the pump outlet and the characteristics of the pump); It will be emptied through the development and change of the pump port, and then there will be a pressure difference with the external atmospheric pressure. Under the pressure difference, water is forced into the water inlet and then discharged from the water outlet. Under the action of kinetic energy transmitted by the motor, water is continuously sucked and discharged, and after development and change, it becomes a relatively stable flow.
Electronic water pumps for new energy vehicles have several applications.
1. Automobile water pumps: automobile electronic water pumps, automobile electric water pumps, automobile parking heater water pumps, preheater water pumps, automobile warm air circulation, automobile engine cooling, automobile battery cooling, motorcycle electric water pumps, etc. Working environment requirements: -40- 120 degrees. Before 20 13, the key to the water pump market was occupied by German WEBBAST, and the domestic electronic water pump that replaced the automobile has been successfully developed, breaking this pattern. 2. Solar water pump: With the help of solar panels, solar water pump has three major functions: (1) energy saving, which is 35% more energy saving than ordinary DC water pump; (2) Soft start function, which can be started normally when the power reaches 1W; (3) It is convenient to set various protection functions, such as overvoltage, overcurrent and temperature protection; And (3) food-grade water pumps: dishwasher water pumps, coffee pot water pumps, water dispenser water pumps, etc. 4. Heating and cooling mattress pumps: water-cooled mattress pumps, water-heating mattress pumps and car cushion pumps. Requirements: Low noise, which can meet the normal requirements within 28dB. 5. Computer water-cooled pump: The key to the customer base is DIY market, which requires low noise and strong power. 6. Water heater pump: So far, there are few electric pumps used in water heaters, and most manufacturers have switched to DC brushless pumps, especially in Southeast Asian countries, such as Xinma. Because it is safe, energy-saving, small in size, long in service life and convenient to adjust. 7. Water pump for water chillers: All small and medium-sized water chillers in China have been replaced by DC brushless pumps from the previous diaphragm pumps, and the water pump has become the norm of the water pump industry for small and medium-sized water chillers, with stable pressurization, low noise and a service life nearly 10 times longer than that of diaphragm pumps. 8. Air-conditioning cold water pump: widely used in communication cabinet cooling, machine tool water circulation cooling, etc. 9. Floor heating circulating water pump, solar fountain water pump, portable water heater water pump, portable bathing machine water pump, etc.
New energy vehicles have several characteristics of electronic water pumps.
It combines the advantages of self-priming pump and chemical pump, and is synthesized from various imported corrosion-resistant materials. It has the properties of acid resistance, alkali resistance and corrosion resistance. The self-priming speed is extremely fast (about 1 sec), the suction force is strong, the suction distance is as high as 5 meters, and there is basically no noise. Exquisite workmanship, self-priming function, large flow (up to 25 liters/minute), high pressure (up to 2.7 kilograms), stable performance and convenient installation. Therefore, this kind of high-flow water pump is often used in new energy vehicles.
How many electronic water pumps are used in new energy vehicles? Bian Xiao Auto shared the introduction, application scope and characteristics of electronic water pumps with friends. So, after seeing the sharing of Bian Xiao, do friends understand the concept of D electronic water pump? I think new energy vehicles have become a major trend in the future and a key tool for future travel, so friends still need to know more about new energy vehicles.
