Is the electric pump of compression bag the same for every brand?

The air pump of vacuum compression bag is universal, with suction nozzle and exhaust nozzle, which can continuously form vacuum or negative pressure at the entrance; A slight positive pressure is formed at the exhaust nozzle; The working medium is mainly gas.

The working principle of air suction pump is the same as that of micro vacuum pump, which is the circular motion of motor. The diaphragm inside the pump moves back and forth through mechanical devices, thus compressing and stretching the air in the pump cavity with a fixed volume, forming a vacuum (negative pressure), which makes the suction port of the pump have a pressure difference with the external atmospheric pressure. Under the action of pressure difference, gas is forced (sucked) into the pump cavity and then discharged from the exhaust port.

It is precisely because the pressure difference between the air outlet and the outside atmosphere can be formed, and at the same time, unlike large vacuum pumps that need lubricating oil and vacuum pump oil, it will not pollute the working medium, and has the advantages of small volume, low noise, maintenance-free, and 24-hour continuous operation.

Select key points

First, the input of compressed air: that is, it is only used for pumping and inflating, and the pump suction port is basically not used. This situation is relatively simple, and the output pressure can be selected in descending order: PCF50 15N, FAA8006, FAA6003, FAA4002, FM2002, FM 100 1+0. Of course, we should also refer to relevant technical parameters such as flow indicators.

2. Pumping or pumping: pumping or vacuumizing with a micro pump, but sometimes liquid water enters the pump cavity; Micro-pump is required to pump both air and water. Pump water mainly by micro-pump, but do not want to rely on manual "water diversion" to pump water; Pump water with a micro-pump, but sometimes the pump may have no water to pump and be in a "dry operation" state. In these cases, WKA series should be selected.

3. Used for air extraction: Micro pumps used for air extraction are divided into two types: gas sampling pump and micro vacuum pump. Gas sampling pumps are: PM series; Micro vacuum pumps include: VM series, VAA series, PK series, PC series, VCA series, VCC series, VCH series, PH series, FM series, FAA series and PCF series.

Fourthly, if the pump itself needs to adjust the flow and vacuum, and there is a liquid crystal panel to display the vacuum, you need to choose the intelligent vacuum pump ANB series. Intelligent vacuum pump, because of its intelligence and automation, does not need to increase valves and control circuits to adjust flow and vacuum.
