Micro air pump, mainly used for gas sampling, gas circulation, vacuum adsorption, vacuum pressure holding, pumping, pumping, pressurization and other gas transportation;

Micro air pump is divided into: micro negative pressure pump, micro vacuum pump, micro gas circulation pump, micro gas sampling pump, micro pumping pump, micro pumping pump, micro pumping pump dual purpose pump;

General medical and health, scientific research, laboratory, environmental protection, instrumentation, chemical and other industries widely applicable micro air pump mainly refers to the micro vacuum pump.

Classification of working principles

Diaphragm pump

Have entered a suction mouth, each an exhaust nozzle, gas mouth place for one-way valve, under the eccentric circular motion of the motor drive, the inside of the pump diaphragm do reciprocating motion, and compressed air, stretching pump cavity form the negative pressure, the bleeding point at atmospheric pressure with the outside world to generate differential pressure, under the action of pressure difference, the bleeding point check valve to open, make the gas suction pump cavity, And then out of the exhaust port.
