The vacuum pump refers to one with one breath (water) mouth and exhaust mouth (water) that can be moved in and out, and can continue to form vacuum or negative pressure at the import of imports; A kind of instrument that can be gas or liquid, a small volume, is often called "micro vacuum pump", also referred to as "vacuum pump". Basic principles of micro vacuum pump: The circular motion of the motor, through the mechanical device to make the diaphragm inside the pump, a duplex movement, thereby compressing the air in the pump cavity of the fixed -volume pump. The pressure difference between the atmospheric pressure at the outside and the outside world is caused by the pressure. Under the influence of the pressure difference, the gas pressure (suction) of the gas (sucking) into the pump cavity is discharged from the exhaust port.
