What is a miniature vacuum pump?

Miniature vacuum pump, simply means: with one out of the exhaust nozzle, the exhaust nozzle of each one, and at the inlet can continue to form a vacuum or negative pressure; exhaust nozzle at a slight positive pressure; working medium mainly For the gas, a compact instrument. A few examples are as follows: For example, a closed container (initially 100 KPa at normal pressure) is connected to the VAA6005 miniature vacuum pump, which is continuously evacuated. Finally, the pressure of the gas in the closed container will be lower than the atmospheric pressure Absolute pressure of 60KPa. Not only that, through special technical improvements, in addition to a single suction miniature vacuum pump, but also can form a suction pump dual-purpose miniature vacuum pump (ie the exhaust end can produce relatively large positive pressure) such as PCF, FAA series for Supercharged, inflated to overcome the system resistance and so on, as well as the very unique WKA series water and gas micro-vacuum pump, which can be used for long-term idling, dry rotation and so on, unlike the general pump idling, or dry will be damaged Pump. It is precisely because the exhaust port or the exhaust port can form a pressure difference with the outside atmosphere, unlike large vacuum pumps require oil and vacuum pump oil, will not pollute the working medium, and has a compact, low noise, maintenance-free, continuous 24 Hour operation, etc. Therefore, miniature vacuum pump is widely used in medical, health, scientific research, environmental protection and other fields because it is widely used in gas sampling, gas circulation, vacuum adsorption, accelerated filtration, automotive vacuum booster and the like. .
