Intelligent vacuum pump, as the name implies, is intelligent and automatic vacuum pump. Generally, it refers to the micro vacuum pump | small vacuum pump | micro air pump | which integrates sensors, vacuum meters, single-chip microcomputer and other monitoring systems. It can adjust the key parameters of vacuum pump, such as vacuum degree (negative pressure) and flow rate in real-time and automatically, so as to complete the general need to build a more complex system, such as vacuum pressure maintaining, automatic timing shutdown, starting, timing and quantitative vacuum filtration, etc A variety of functions.
Compared with the weight and huge volume of the large vacuum pump, the weight and volume of the intelligent vacuum pump are much smaller, even portable; therefore, they are often called intelligent vacuum instrument, desktop vacuum pump, automatic vacuum pump and portable vacuum pump.
1、 Features of intelligent vacuum pump
1. It can adjust the vacuum degree needed in the actual work, set and display the vacuum degree (negative pressure) value in real time through the integrated digital LCD panel;
2. The flow can be adjusted;
3. The high-quality valve and high-quality flow control circuit are developed, which greatly saves the time and energy to adjust the flow rate;
4. Built in micro vacuum pump with low interference and long service life; with special noise elimination system and independent damping system, the intelligent vacuum pump can work for a long time with low noise and reliability;
5. The core component is a micro vacuum pump, so it inherits the advantages of oil-free, pollution-free and 24-hour operation of the micro vacuum pump. It belongs to the real dry-type vacuum pump, so it does not need maintenance and does not need to add lubricating oil and vacuum pump oil
6. AC 220 V power supply, plug and play.
2、 Three working modes of intelligent vacuum pump
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 and lower limits of the required vacuum can be set. When the pump reaches the upper limit of vacuum, the pump will stop automatically. When the true empty degree drops to the lower limit, the pump will start automatically.
Application scope: vacuum pressure keeping for closed container
Example: if anb2005 intelligent vacuum pump (its maximum negative pressure - 80kPa) is used to maintain vacuum pressure for a closed container, and the internal negative pressure is always maintained at - 60kpa, the upper limit can be set as - 55kpa, and the lower limit is - 65kpa. During this period, when the negative pressure in the container reaches the upper limit, the pump will automatically stop; Then, as the negative pressure of the closed container decreases and is lower than the lower limit, the pump will start automatically, so that the negative pressure in the container will be maintained at - 60kpa at the end, so as to achieve the purpose of vacuum pressure maintaining.
2. Timing mode
The working time of the pump can be set, and the pump will stop automatically after the set time. The maximum allowable time is 99 hours and 59 minutes, and the minimum time is 1 minute.
Application scope: the time of vacuum pumping can be controlled (timing shutdown)
Example: in order to make the negative pressure in a closed container reach - 80kPa, use the intelligent vacuum pump anb2005 (its maximum negative pressure - 80kPa [2]) to pump the container. If the container is small, such as 1-2l, the time can be set for several minutes; otherwise, the time needs to be set longer. Anb2005 will stop automatically when the time is up.
3. Extreme operating mode
The upper limit value of vacuum degree can be set. When the pump reaches the vacuum degree, it will stop automatically.
Application example: set vacuum threshold value, automatic shutdown (quantitative and fixed negative pressure shutdown)
Example: suppose that in an experiment, when the negative pressure in the container reaches - 70kpa, the experimental effect is the best. You can set the upper limit of anb2005 to - 70kpa, then the intelligent vacuum pump will automatically stop when it reaches - 70kpa.
