The working principle of the air extraction pump is the same as that of the micro vacuum pump
The working principle of the air extraction pump is the same as that of the micro vacuum pump, which is the circular movement of the motor. The diaphragm inside the pump is reciprocating through the mechanical device, so as to compress and stretch the air in the pump chamber with a fixed volume to form a vacuum (negative pressure). A pressure difference is generated between the pump air extraction port and the external atmospheric pressure. Under the effect of the pressure difference, the gas is pressed (sucked) into the pump chamber and then discharged from the exhaust port. It is precisely because the air extraction port or the air extraction and exhaust port can form a pressure difference with the outside atmosphere. At the same time, unlike large vacuum pumps, they do not need lubricating oil and vacuum pump oil, do not pollute the working medium, and have the advantages of small size, low noise, maintenance free, 24-hour continuous operation, etc., so the micro vacuum pump is widely used as a power device for gas sampling, gas circulation, vacuum adsorption, accelerated filtering Automobile vacuum assist is widely used in medical, health, scientific research, environmental protection and other fields.
