Why does the vacuum disappear quickly after turning off the power?

When we turn on the power of the micropump to create a vacuum, the pump will pull out the air in the container, reducing the internal air pressure, thus forming a vacuum. But when we turn off the power of the vacuum pump, the pump no longer works, and the inside of the container is in contact with the outside air. The air will naturally enter the inside of the container through the pump port, causing the internal air pressure to increase and the vacuum to be destroyed.

The main reason for this phenomenon is that the seal between the pump port and the container is not good enough. If sealed well, it can minimize the possibility of gases entering the container from the outside, thereby extending the time the vacuum is maintained.
In order to increase the vacuum holding time, we can take the following measures:
1. Replace the pump port with a better one or use more professional vacuum pump equipment.
2. Regularly check the sealing condition of the pump port and container, and promptly replenish sealants or replace aging seals.
3. Placing adsorbents, such as activated carbon or molecular sieves, inside the vacuum container can maintain the vacuum for a longer period of time.

In short, we should pay attention to checking the sealing of the equipment to avoid unnecessary waste. At the same time, when using vacuum equipment, you should also read the user manual carefully to understand the correct operating methods and precautions to ensure the stable operation of the equipment and extend its service life.

The above is the reason why the vacuum will disappear quickly after turning off the power and the solution introduced by our VSD motor. For more relevant information, please contact us for professional explanation.
