Micro Electric Air Vacuum Pump DC 3V

How does a Mini Vacuum Pump achieve vacuuming?

The principle of vacuuming the Electric Vacuum Pump is mainly to compress or evacuate the air in the pump chamber through the reciprocating movement of the diaphragm of the internal mechanical eccentric device. When the diaphragm moves upward, the gas in the sealed pump chamber is compressed, the gas pressure increases, the outlet valve is pushed open and flows out. When the diaphragm moves downward, the gas in the pump chamber is diluted, the gas pressure decreases, the gas is sucked in under the action of negative pressure and the inlet valve is closed. As the diaphragm vibrates up and down, the gas in the pump chamber is continuously compressed and pull out to create a vacuum state.

How to evaluate the vacuuming capacity of a Mini Electric Vacuum Pump?

1. Ultimate vacuum degree: Connect the Portable Vacuum Pump to the detection container, put in the gas to be measured, and continue to pump for a long time. When the gas pressure in the container.When the force no longer decreases and maintains a certain value, this pressure is called the ultimate vacuum degree of the pump. The smaller the ultimate vacuum degree, the closer the micro diaphragm vacuum pump is to the theory vacuum.

2. Pumping rate: the volume of gas flowing through the suction port of the micro diaphragm vacuum pump per unit time. The greater the pumping rate, the better the performance of the micro diaphragm vacuum pump the stronger the pumping ability.

3. Work efficiency: The dc mini vacuum pump needs to consume energy during the working process, and convert this energy into the output pressure and flow rate of the pump, thereby achieving air control aspiration of body or liquid. The higher the working efficiency of the pump, the greater the output pressure and flow rate, and the stronger the pumping capacity.

4. Noise and vibration: Micro diaphragm vacuum pumps will produce certain noise and vibration during work. These factors will affect the performance and comfort of the pump noise The smaller the sound and vibration, the better the performance of the micro diaphragm vacuum pump and the more stable the pumping capacity.

Can I use Mini Diaphragm Pump as mini vacuum pump?

Diaphragm pumps usually generate vacuum by mechanical rotation or compressed air, and their working principles are different from vacuum pumps. When choosing to use a diaphragm pump for vacuum processing, you need to select the appropriate model and parameters based on actual needs and scenarios.

In addition, it should be noted that the diaphragm pump requires a certain pressure difference on both sides of the diaphragm to operate normally, and there is no gas in the vacuum state, so the diaphragm pump may not work properly in the vacuum state. If you need to use a diaphragm pump for vacuum processing, it is recommended to first understand its working principle and applicable scenarios, and choose the appropriate model and parameters.

Is it better to have more or less vacuum pressure for a Micro Electric Vacuum Pump?

The vacuum pressure of the electric vacuum pump needs to be selected according to actual needs. There is no absolute "more" or "less".

When selecting a Membrane Vacuum Pump, you need to consider whether its vacuum pressure range meets actual needs. If the vacuum pressure range of the micro diaphragm vacuum pump is too large, it may result in wasted energy and excessive noise; if the vacuum pressure range of the micro diaphragm vacuum pump is too small, it may not be able to meet actual needs. Therefore, when selecting a micro diaphragm vacuum pump, it is necessary to select and match it according to actual needs to ensure that it can meet the usage requirements. For example, if you need to extract a large amount of air or require a higher vacuum degree, you need to choose a micro diaphragm vacuum pump with a larger vacuum pressure range; conversely, if you only need to extract a small amount of air or require a lower vacuum degree, you can choose a vacuum pressure range Smaller miniature diaphragm vacuum pump.
