Electric Water Pump, many new energy vehicles, RVs and other special vehicles are often used in miniature water pumps as water circulation, cooling or on-board water supply systems. Such miniature self-priming water pumps are collectively referred to as automotive electric water pumps. The circular motion of the motor makes the diaphragm inside the pump reciprocate through the mechanical device, thereby compressing and stretching the air in the pump cavity (fixed volume), and under the action of the one-way valve, a positive pressure is formed at the drain (actual output The pressure is related to the power boost received by the pump outlet and the characteristics of the pump); a vacuum is formed at the suction port, thereby creating a pressure difference with the external atmospheric pressure. Under the action of the pressure difference, the water is pressed into the water inlet, and then discharged from the outlet. Under the action of the kinetic energy transmitted by the motor, the water is continuously sucked and discharged to form a relatively stable flow.
Features:
Automobile water pumps generally have a self-priming function. Self-priming means that when the suction pipe of the pump is filled with air, the negative pressure (vacuum) formed when the pump is working will be lower than the water pressure at the suction port under the action of atmospheric pressure. up and out from the drain end of the pump. There is no need to add "diversion water (water for guidance)" before this process. The miniature water pump with this self-priming ability is just called "miniature self-priming water pump". The principle is similar to a micro air pump.
It combines the advantages of self-priming pumps and chemical pumps, and is made of a variety of imported corrosion-resistant materials, which have properties such as acid resistance, alkali resistance, and corrosion resistance; the self-priming speed is extremely fast (about 1 second), and the suction Range up to 5 meters, basically no noise. Exquisite workmanship, not only self-priming function, but also large flow rate (up to 25 liters per minute), high pressure (up to 2.7 kg), stable performance, and easy installation. Therefore, this large flow electric bus water pump is often used in new energy vehicles.
Notice!
Although some micro pumps also have self-priming ability, their maximum self-priming height actually refers to the height that can lift water "after adding water", which is different from "self-priming" in the true sense. For example, the target self-priming distance is 2 meters, which is actually only 0.5 meters; and the micro self-priming pump BSP-S is different, its self-priming height is 5 meters, without water diversion, it can be lower than the pump water end by 5 meters The water is pumped up. It is "self-priming" in the true sense, and the flow rate is much larger than that of ordinary micro-pumps, so it is also called "large-flow self-priming pump".
