With the further requirement of miniaturization and non polluting working medium of vacuum pump in all walks of life, miniaturized vacuum pump with small volume, oil-free, maintenance free, low noise, environmental protection and energy saving has been widely used. Micro vacuum pump refers to a small volume vacuum pump, which has only one suction nozzle and one exhaust nozzle, and can continuously form vacuum or negative pressure at the inlet; the working medium is mainly gas, which is a compact instrument.
The basic principle is: the circular motion of the motor makes the diaphragm inside the pump reciprocating motion through the mechanical device, so as to compress and stretch the air in the fixed volume pump cavity to form a vacuum (negative pressure), and generate a pressure difference with the external atmospheric pressure at the pumping port of the pump, under the effect of the pressure difference, the gas pressure (suction) into the pump cavity, and then discharge from the exhaust port.
Micro vacuum pump commonly used portable instruments gas sampling, sampling, gas circulation, mobile, handheld devices and other gas sampling, object adsorption, vacuum pressure. It can also be used for long-term idling, dry running and other occasions, widely used in scientific research, laboratory, environmental protection, instrumentation, chemical industry, medical oxygen generator, medical test equipment, beauty and body equipment, automation equipment, printing and printing machine, electronic and electrical work.
