Electric DC6.0V mini air pump for body massager

Do micro diaphragm air pumps require electricity? What are the ways to power on？

Micro diaphragm air pumps usually do not require electricity because they are driven by compressed air as the power source to operate the pump body, rather than causing using electricity. Therefore, there is no way to power on the micro diaphragm air pump. In some specific application scenarios, there may be micro electric diaphragms demand for pumps, this type of pump uses a micro DC motor as the power drive device. For this type of micro Electric Diaphragm Pump, the electrification method usually connected to a power supply through standard wires, the voltage of the power supply may be 5V, 12V, 24V, etc. The connection methods may include directly inserted, screw fixed, or welded, depending on the design and application requirements of the pump.

Overall, the micro diaphragm air pump itself does not require electricity, but is driven by compressed air. If you need to learn more about special information on a specific type of Micro diaphragm pump, it is recommended to refer to its product manual or consult relevant technical personnel.

How does the compressed air of a micro diaphragm air pump drive the operation of the pump body?

1. Compressed air introduction: Compressed air is introduced into the diaphragm chamber of the diaphragm pump through the intake valve. The diaphragm chamber is a sealed space inside the pump body, with two diaphragms on each side that are tightly connected to the inner wall of the pump cylinder.

2. Diaphragm bulging: When compressed air enters the diaphragm chamber, the diaphragm will bulge under pressure. This bulging action will drive the contents of the diaphragm chamber (usually liquid) into the discharge chamber.

3. Fluid delivery: With the continuous stirring of the diaphragm, the liquid will be pushed to the discharge chamber and discharged from the pump outlet, achieving fluid delivery.

4. Function of one-way valve: To ensure that fluid can only flow in one direction, Diaphragm Pumps are usually equipped with one-way valves. When the diaphragm contracts, the one-way valve closes to prevent fluid backflow. When the diaphragm bulges, the one-way valve opens, allowing fluid to enter the discharge chamber.

5. Air pressure regulation: In order to accurately control fluid flow, diaphragm pumps may also be equipped with air pressure regulators. By adjusting the compressed air pressure entering the diaphragm chamber, the degree of diaphragm agitation can be controlled, thereby achieving precise control of fluid delivery volume.

Technical Specification

What is the impact of liquid in the gas path or outlet of a micro diaphragm air pump on the compression efficiency of the pump

The presence of liquid in the gas path or outlet of a micro diaphragm air pump can have a negative impact on the compression efficiency of the pump.

Firstly, liquid entering the gas path can cause blockage, increasing the resistance of gas flow. In this way, the compression efficiency of gas passing through the gas path will decrease because the gas needs to overcome greater resistance in order to be compressed and discharged.

Secondly, the presence of liquids may also corrode or damage the internal components of the pump, such as sealing rings, pump film, etc. The damage to these components can further affect the performance and compression efficiency of the pump, and may even lead to pump failure.

In addition, the presence of liquid may also affect the sealing performance of the pump, leading to gas leakage. Gas leakage not only reduces the compression efficiency of the pump, but also increases energy consumption and operating costs.

Dimension Drawing

1. Fluid dynamic noise: This is due to the continuous generation of fluid pressure pulses by micro pumps during operation, which excites the vibration of pump bodies, valves, pipelines and other components and radiates noise to the outside world. During the exhaust process of the air pump, when the inlet valve is closed and the outlet valve is opened, the air quickly flows through the outlet to form sound waves, which in turn generates exhaust noise.

2. Mechanical noise: This mainly comes from the vibration and friction of internal components such as membranes, bearings, crankshafts, and connecting rods in the pump. When these components experience abnormal movement due to wear or imbalance, it can cause mechanical noise.

3. Air valve noise: Poor sealing of the air valve or excessively tight springs may also cause noise to occur. When the air valve cannot be tightly closed or the spring is too tight, the airflow passing through the air valve will generate eddy currents and impacts, resulting in noise.

4. Motor noise: As the power source of the air pump, the motor's bearing wear or imbalance can also cause noise. In addition, the electromagnetic noise of the motor is also a source of noise.

5. Pipeline resonance: If the pipeline design is unreasonable or the material selection is improper, it may cause pipeline resonance when the airflow passes through the pipeline, resulting in noise. To reduce these noises, various measures can be taken, such as optimizing the design of pumps and motors, selecting low-noise materials, adding sound insulation equipment, regular maintenance, and cleaning.

How to effectively reduce the noise of micro diaphragm air pumps?

1. Use of noise reduction materials: install noise reduction materials around the air pump, such as foam plastic, glass wool, etc., which can effectively absorb and isolate noise, thus reducing noise transmission.

2. Reduce sound transmission paths: Try to separate the air pump from other machines and equipment to reduce the path of noise transmission. At the same time, it is also possible to consider setting up sound barriers or covers around the air pump to further reduce the transmission of noise.

3. Adjusting the working state of the pump: By adjusting the working state of the air pump, such as reducing flow rate, adjusting speed, etc., the compression sound and oscillation of the fluid can be reduced, thereby reducing the generation of noise. However, it should be noted that adjusting the working state may affect the performance and output of the air pump.

4. Replace low-noise pump: If the above measures cannot effectively reduce noise, consider replacing the low-noise micro diaphragm air pump. When purchasing, you can choose products with lower noise indicators and follow the correct selection principles to ensure that the pump operates under optimal operating conditions.

5. Optimize pipeline design: reduce the number of bends in the pipeline, avoid excessively long pipelines, and try to use pipelines with larger diameters. Optimizing pipeline layout helps to reduce pump operating resistance and reduce noise.

6. Shock absorption measures: When installing the air pump, use shock absorption pads or shock absorbers to reduce vibration transmission and reduce noise. Ensure that the pump is perpendicular to the ground to reduce vibration during operation.
