7.4V DC mini air pump for Beauty-care equipments

What is the function of the air pump?

1. Air pumping: The micro-diaphragm air pump can pump gas from the low-pressure area into the high-pressure area through the working principle of the pump to achieve the air pumping function. In laboratories, it is often used for operations such as air sample extraction and vacuum filtration.

2. Compression: The micro-diaphragm air pump can compress gas from a low-pressure area to a high-pressure area to achieve gas boosting function. In medical equipment, it is often used for gas transportation, gas pressurization and other operations.

3. Transmission: The micro-diaphragm air pump can push the liquid from the low-pressure area to the high-pressure area through the working principle of the pump to realize the liquid transportation function. In the fields of chemical industry and environmental protection, it is often used in operations such as liquid transportation and liquid circulation.

4. Gas sensing: During the working process of the micro diaphragm air pump, the gas sensing function can be realized by detecting the pressure change of the pump. In instrumentation, it is often used for gas detection, gas analysis and other operations.

What does Dc Air Pump stand for?

DC air pump refers to an air pump powered by DC power supply. Specifically, the DC air pump uses a DC power supply, and its power supply voltage can be of various types, such as DC 12V, DC 24V, and DC 48V. This type of air pump is usually powered by an electric motor and may contain a reducer to convert the motor's speed into the required torque

DC air pumps are widely used in many fields. In the electronics field, with the gradual miniaturization of electronic products, AC and DC air pumps have become an important supply in the electronics industry due to their advantages such as small size, light weight, low noise, long life, and reliable performance.  

What is a brushed DC air pump?

The brushed DC air pump is an air pump driven by DC power, which uses a brushed DC motor as the driver. A brushed DC motor is a motor that can change the direction of the rotor's magnetic field by changing the direction of the current, so the rotor can rotate. The brushed DC air pump uses the rotation of the brushed DC motor to generate airflow, thereby realizing the transportation and extraction of gas.

The brushed DC air pump has the following features:

1. High efficiency: Brushed DC motors have higher efficiency and can convert electrical energy into mechanical energy at a higher rate.

2. Good speed regulation: By changing the size and direction of the current, the speed of the air pump can be adjusted to adapt to different work needs.

3. Compact size: The brushed DC motor has a simple structure and small size, making it easy to integrate and install.

4. Long life: Brushed DC motors have a long life and can operate stably for a long time.

5. Smooth operation: The brushed DC motor rotates smoothly with less vibration and noise.

What is the difference between a brush DC air pump and a carbon brush DC air pump?

Brush DC air pumps and carbon brush DC air pumps are two different types of DC air pumps. The differences between them are mainly reflected in the following aspects:

1. Manufacturing materials: Brush DC air pumps usually use copper brushes and iron cores, while carbon brush DC air pumps use brushes and iron cores made of carbon materials.

2. Service life: Since carbon brushes have a high friction coefficient, the service life of a carbon brush DC air pump is relatively short, usually several thousand hours. The brush DC air pump has a longer service life, usually reaching tens of thousands of hours.

3. Efficiency: The efficiency of carbon brush DC air pumps is low, usually around 40%, while the efficiency of brush DC air pumps is relatively high, usually above 70%.

4. Noise: The carbon brush DC air pump will produce greater noise during operation, while the brush DC air pump will have less noise.
