How is the torque of the micro diaphragm pump generated?
1. Power device: Micro diaphragm pumps usually use micro DC motors (such as motors with voltages of 12V and 24V) as power drive devices. The circular motion of this motor is the starting point for torque generation.
2. Mechanical eccentric device: The motor drives the internal mechanical eccentric device to perform eccentric motion. This eccentric motion is a key step in torque transmission because it can convert the circular motion of the motor into the reciprocating motion of the diaphragm.
3. Diaphragm reciprocating motion: The diaphragm driven by the eccentric motion performs reciprocating motion. This is the result of the direct action of the torque and is also the key to achieving liquid suction and discharge.
4. Valve body synergy: During the reciprocating motion of the diaphragm, the two valve bodies (suction valve and discharge valve) in the micro diaphragm pump work together. When the diaphragm moves inward, the pressure in the pump chamber drops, the suction valve opens, and the liquid is sucked in; when the diaphragm moves outward, the pressure in the pump chamber rises, the discharge valve opens, and the liquid is discharged. This synergy ensures the normal flow of the liquid.

What influence does the torque of a mini air pump have on the air pump?
1. Flow and pressure output:
Air pumps with larger torque can produce higher output pressures because torque directly affects the reciprocating speed and stroke of the diaphragm, thereby affecting the pressure changes in the pump chamber.
At the same speed, air pumps with larger torque can generally deliver larger flows. This is because greater torque means that the diaphragm can move more liquid or gas in each reciprocating motion.
2. Efficiency and energy consumption:
The appropriate torque size can improve the efficiency of the air pump, allowing it to produce the required pressure and flow at lower energy consumption. However, excessive torque may lead to increased energy consumption because more energy is required to drive the diaphragm movement.
On the other hand, too little torque may cause the air pump to fail to produce enough pressure and flow, thereby reducing its efficiency.

What influence does the torque of a electric air pump have on the air pump?
3. Life and reliability:
The size of the torque also affects the life and reliability of the dc air pump. Excessive torque may cause excessive load on the mechanical parts of the air pump, resulting in increased wear, increased failure rate and shortened life.
Appropriate torque can ensure that the air pump has a long service life and a low failure rate while operating stably.
4. Noise and vibration:
The size of the torque may also affect the noise and vibration level of the air pump. Excessive torque may cause the air pump to generate greater vibration and noise during operation, affecting the use environment and user experience.
DYX Diaphragm Pumps And Soelnoid Valves Application
What kind of motor can be used for mini electric air pump?
Brushed motor, brushless motor, carbon brush motor
This motor structure determines that the application of brushed motors in micro diaphragm air pumps has its specific advantages. For example, the speed regulation process of brushed motors is mainly to adjust the voltage of the motor power supply, which makes the speed regulation relatively simple and direct. In addition, the price of brushed motors is usually more economical than brushless motors, which is also an important factor in considering the use of brushed motors in some applications.
