5 FAQ About Micro Air Pump / Mini Vacuum pump

Professional micro pump manufacturer

1. The difference between brushless mini vacuum pump and brushed mini vacuum pump.

Advantages of brushless miniature air pump/vacuum pump: long life, no electromagnetic interference, low noise, especially suitable for continuous operation around the clock or frequent start/stop occasions, many functions (PWM, CW&CCW, FG, BRAKE); disadvantages: negative pressure, positive pressure, flow rate and other parameters are smaller than those with brushes; the cost is higher than those with brushes.

Brush micro air pump / vacuum pump advantages: low cost, high motor torque parameters; disadvantages: can not work for a long time, brush micro pump life is shorter than the brushless micro pump life.

2. What are the allowable ambient temperature and medium temperature of micro vacuum pump?

The working environment of miniature vacuum pump: ambient temperature: 0℃～50℃ (no condensation), the pump should not be exposed to outdoor sunlight, and should work in a clean and ventilated environment. Ambient relative humidity: ≤90%. The working medium of miniature vacuum pump: the gas extracted by the pump must be free of particles and oil, and it is allowed to be rich in water vapor, but no liquid water can enter the pump.

3. How to understand the load of micro pump?

In the industry of miniature air pump, "load" actually refers to the resistance and obstruction of the gas in the process of running; it needs the air pump to do work to overcome this resistance; the stronger the ability to overcome this resistance, the stronger the "carrying capacity" of the miniature air pump.

4. The common units of mini air pump/vacuum pump are:

Pressure: Pa, Kpa, Mpa, mmHg, mbar, bar, psi

Flow: L/min, LPM, L/M

5. The influence of the parameters of micro air pump/vacuum pump on the price.

Micro vacuum pump, micro air pump, the main parameters are flow, positive pressure, negative pressure (vacuum), etc. The higher the parameters, the higher the cost of workmanship required, the sales price will certainly be correspondingly higher.
