Micro air pump can directly adjust the negative pressure?
[Features]
(1) Can adjust the vacuum required in the actual work, can be set and through the integrated digital LCD panel, "real time" display the vacuum (negative pressure) value;
(2) The flow rate can be adjusted;
(3) Equipped with highly sensitive imported sensors, high quality flow control valves and precision control circuit, to complete the "automatic adjustment" function, greatly saving the time and energy of developers;
(4) Built-in low interference, long life miniature vacuum pump; With the miniature air pump special muffler system and independent shock absorption system, to ensure that the intelligent vacuum pump can work for a long time, low noise, reliable;
(5) The core component is a miniature vacuum pump, so it inherits the advantages of the miniature vacuum pump without oil and pollution, and can run continuously for 24 hours. It is a dry vacuum pump worthy of the name, so there is no need to maintain, no need to add lubricating oil and vacuum pump oil; Intelligent vacuum pump back
(6) AC power supply, plug and play
[Detailed introduction and examples]
The intelligent vacuum pump can automatically adjust the vacuum degree and flow rate through three unique working modes: interval, timing and limit.
1. Interval working mode
The upper limit and lower limit of the required vacuum can be set. When the pump reaches the upper limit of the vacuum, it will automatically stop, and when the vacuum drops to the lower limit, the pump will automatically start.
Application: vacuum pressure preservation for closed containers, etc
Example: If the intelligent vacuum pump (its maximum negative pressure -) is used to carry out "vacuum pressure preservation" on a closed container, so that the internal negative pressure is always maintained at about -, the upper limit can be set as -, the lower limit as -, during the negative pressure in the container reaches the upper limit, the pump will automatically stop; Then, with the leakage negative pressure of the closed container itself reduced, below the lower limit, the pump will automatically start, so that the negative pressure in the container to the end of the maintenance of about -, to achieve the purpose of vacuum pressure preservation.
2. Timed working mode
The working time of the pump can be set, and the pump will stop running automatically after the set time. The maximum duration is 99 hours and 59 minutes, and the minimum duration is 1 minute.
Scope of application: controlled vacuum time (timed shutdown)
Example: To make the negative pressure in a closed container reach -, use an intelligent vacuum pump (its maximum negative pressure -[2]) to pump the container. If the container is small, such as 1-2L, the time can be set as several minutes; Otherwise, you need to set the time to be longer. When the time is up, it will stop automatically.
3. Extreme working mode
An upper limit of vacuum degree can be set. When the pump reaches the vacuum degree, it will stop automatically.
Application example: Set vacuum threshold, automatic stop (quantitative negative pressure stop)
Example: Suppose that in an experiment, when the negative pressure in the container is required to reach -, the experimental effect is the best, the upper limit can be set as -, then the intelligent vacuum pump will automatically stop when it reaches -, to achieve the purpose.
