1、 Definition and composition of Mini DC Water Pump

Micro DC Diaphragm Water Pump, also known as liquid transfer pump, is an innovative water pump technology. This type of water pump is mainly composed of a motor and a pump body, with a small and compact size. The design form is a motor+pump body, and the pump body has two interfaces, one inlet and one outlet. Among them, water enters from the inlet, passes through the diaphragm inside the water pump, is compressed, stretched, and finally discharged from the outlet. The biggest feature of this type of water pump is its reciprocating diaphragm, which makes the water flow stable and continuous.

2、 The working principle and effect of Small Electric Membrane Pump

The working principle of Mini Water Pump is based on the circular motion of the motor. The movement of the motor is transmitted through a mechanical device to the diaphragm inside the feed pump, causing the diaphragm to undergo reciprocating motion. This reciprocating motion compresses and stretches the air inside the pump chamber (fixed volume), forming a pressure difference. Under the pressure difference, water is pressed into the inlet and then discharged from the outlet. At the same time, under the action of the one-way valve, a positive pressure is formed at the discharge port (the actual output pressure is related to the resistance of the pump discharge port and the characteristics of the pump), and a vacuum is formed at the pumping port, resulting in a pressure difference with the external atmospheric pressure. Under the influence of pressure difference, water is continuously sucked in and discharged, forming a relatively stable flow rate.

Application Fields and Advantages of Micro DC Diaphragm Water Pumps

Micro DC diaphragm water pumps are widely used in various fields due to their unique structure and efficient working principle. For example, it can play an important role in fields such as household appliances, medical equipment, and personal care electronic products. Its biggest advantage lies in its small size, light weight, easy installation and use, as well as high flow stability and energy-saving performance.

When installing a micro DC diaphragm water pump, it is necessary to ensure that the inlet and outlet of the pump are correctly connected to relevant pipelines or equipment to avoid water leakage or air mixing. At the same time, correct wiring should be carried out according to the operating instructions of the motor, and attention should be paid to grounding safety. During use, the working condition of the water pump and the temperature of the motor should be regularly checked. If any abnormalities occur, the machine should be immediately shut down for inspection.
