Advantage:
Because the suction or exhaust port can form a pressure difference with the outside atmosphere, and unlike large vacuum pumps need lubricating oil and vacuum pump oil, will not pollute the working medium, and has the advantages of small size, low noise, no maintenance, can run continuously for 24 hours, so the miniature vacuum pump is used as a power device. Widely used in gas sampling, gas cycling, vacuum adsorption, accelerated filtration, automotive vacuum power and other occasions, in the medical, health, scientific research, environmental protection and other fields have been widely used
