How the micro water pump works

Nowadays, water pumps have become an indispensable part of our lives.There are many types of pumps, and small water pumps are one of them. Small pumps are lightweight and easy to carry. The following are the problems encountered in the operation of the micro water pump and the micro diaphragm water pump introduction,Hope it will be helpful to you who use micro water pump daily.

Is there any damage to the miniature DC water pump when the current is too large? For the DC power supply equipped with the micro DC water pump, if the current of the power supply is less than the nominal working current of the pump, there will be insufficient power supply and insufficient parameters of the micro pump (such as flow, pressure, etc.).

As long as the voltage of the DC power supply is the same as that of the pump, and the current is much larger than the nominal current of the pump, this situation will not burn the pump.

The main parameters of the switching power supply are the output voltage and output current that are most closely related to the pump. For the pump to work normally, the output voltage needs to be consistent with the working voltage of the pump, such as 12V DC; The output current of the power supply is greater than the nominal operating current of the pump. There is no need to worry about the large current of the power supply, which will burn the pump if it exceeds the nominal working current of the pump.Because the current of the switching power supply, battery or battery is large, it only means that the current capacity that the power supply can provide is large. The current provided by the power supply during actual operation is not always provided by the nominal current of the power supply, but depends on the load of the pump; When the load is large, the current required by the power supply to the pump is large; otherwise, it is small.

What is a miniature diaphragm pump

Micro-diaphragm water pump refers to a water pump with one inlet and one outlet and one drain outlet, and can continuously form vacuum or negative pressure at the inlet; A large output pressure is formed at the drain; the working medium is water or liquid; a compact instrument. It is also called “micro liquid pump, micro water pump, micro water pump”.

The working principle of micro water pump

It uses the negative pressure generated by the pump to first pump the air out of the water pipe, and then suck the water up. It uses the circular motion of the motor to make 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 water outlet. (The actual output pressure is related to the boost received by the pump outlet and the characteristics of the pump);A vacuum is formed at the suction port, which creates a pressure difference with the outside atmospheric pressure. Under the action of the pressure difference, the water is pressed into the water inlet and then discharged from the drain. Under the action of the kinetic energy transmitted by the motor, the water is continuously inhaled and discharged to form a relatively stable flow.

Advantages of long-life micro-pump series

l It has a dual-purpose pump for air and water, and the working medium can be gas and liquid, no oil, no pollution, and no maintenance;

l Can withstand high temperature (100 degrees); ultra-small size (smaller than the palm of your hand); can be idling for a long time, dry running, pumping water in case of water, and air pumping in case of air;

l Long service life: Driven by high-quality brushless motor, it is manufactured with better raw materials, equipment and technology, and all moving parts are made of durable products, which can improve the life of the pump in an all-round way.lLow interference: it does not interfere with the surrounding electronic components, does not pollute the power supply, and will not cause the control circuit, LCD screen, etc. to crash; l Large flow (up to 1.0L/MIN), fast self-priming (up to 3 meters);

l Perfect self-protection and automatic shutdown function;

The above is the introduction of the working principle of the micro water pump. If you want to know more about the micro water pump, please contact us.
