The principle of micro vacuum pump is simply stated as follows: there is one suction nozzle and one exhaust nozzle, and the vacuum or negative pressure can be continuously formed at the inlet;Micro positive pressure is formed at the exhaust nozzle;Working medium is mainly gas, a small volume of an instrument.
An airtight container (initially, the internal pressure is 100KPa) is connected to the micro vacuum pump SC3704PM for continuous air extraction. Finally, the gas pressure in the airtight container will be lower than atmospheric pressure and reach the absolute pressure of 60KPa.
Because of bleeding point or smoke vent can atmospheric pressure difference with the outside world, and not like a big need lubricating oil vacuum pump and vacuum pump oil, not pollution of the working medium, and small volume, low noise, no maintenance, so according to the principle of the micro vacuum pump, mini vacuum pump was used as a power plant is widely used in gas sampling, gas cycle, vacuum adsorption, accelerate the filtering, automobile vacuum booster, etc., in the medical, health, scientific research, environmental protection and other fields has been widely used.
