Here are some examples:
For example, a closed container (at the beginning, the internal pressure is 100 KPa) is connected to a miniature vacuum pump VAA6005, and it is continuously evacuated. Finally, the gas pressure inside the sealed container will be lower than the atmospheric pressure and reach an absolute pressure of 60 kPa.
In addition to this, after special technical improvements, in addition to a single pumping vacuum pump, it is also possible to create a miniature vacuum pump for pumping and air pumping (that is, the exhaust port can produce a relatively large positive pressure), such as the PCF and FAA series. Pressurized, inflated, overcoming system resistance, etc. and the very unique WKA series of water and gas micro-vacuum pumps, it can be used for long-term idling, dry running and other occasions, unlike the general pump idling, or dry running will be damaged Pump.
It is because of the pressure difference between the air intake or exhaust air outlet and the outside atmosphere. At the same time, unlike large vacuum pumps, which require lubricating oil and vacuum pump oil, they do not contaminate the working medium, and they are compact, low-noise and maintenance-free. Hours of operation and other advantages, so the mini vacuum pump is used as a power device, widely used in gas sampling, gas circulation, vacuum adsorption, acceleration filtration, automotive vacuum booster and so on, has been widely used in medical, health, scientific research, environmental protection and other fields .
