III. Working Principles of 12V Water Pumps

12V water pumps usually use direct current motors as power sources. The motors are connected to the pump impellers through coupling or gear transmission devices. When the 12V direct current power supply is connected, the motor starts to rotate, driving the impeller to rotate at high speed. The rotation of the impeller causes the liquid in the pump chamber to be thrown out under the action of centrifugal force, forming a low-pressure area, while the liquid at the inlet of the pump chamber is sucked into the pump chamber under the action of atmospheric pressure, thus realizing the continuous delivery of the liquid. According to different application requirements and design structures, 12V water pumps can be divided into various types such as centrifugal water pumps, peristaltic pumps, and diaphragm pumps.

Centrifugal water pumps have the characteristics of large flow and relatively high head, and are suitable for occasions with high requirements for liquid delivery volume and pressure, such as automobile engine cooling systems and large outdoor shower equipment. Peristaltic pumps transport liquids by squeezing elastic hoses, have the advantages of high precision, good sealing performance, and the ability to transport various liquids with different properties, and are commonly used in medical infusion pumps, syringe pumps, and some chemical experiment equipment with extremely high requirements for liquid delivery precision. Diaphragm pumps use the reciprocating motion of diaphragms to change the volume of the pump chamber to achieve the suction and discharge of liquids. They have strong self-priming ability and can run without load, and are suitable for transporting liquids containing impurities or with high viscosity, such as those used in agricultural sprayers for transporting pesticide and fertilizer solutions.
