Portable vacuum pump refers to a suction nozzle and an exhaust nozzle with one in and one out, and can continuously form vacuum or negative pressure at the inlet. A slight positive pressure is formed at the exhaust nozzle. The working medium is mainly gas, a small size of an instrument. The main advantage of portable vacuum pump is small size, light weight and easy to carry micro vacuum pump.
Portable vacuum pump its working principle is the same as the working principle of micro vacuum pump, are the circular movement of the motor, through the mechanical device to make the diaphragm inside the pump to do reciprocating movement, so as to compress and stretch the air in the fixed volume of the pump cavity to form a vacuum, at the pump pumping port and the outside atmospheric pressure to produce a pressure difference, under the action of the pressure difference, the gas is sucked into the pump cavity, and then discharged from the exhaust port. Because the suction port or suction and exhaust port can form a pressure difference with the outside atmosphere, and unlike large vacuum pumps that require lubricating oil and vacuum pump oil, will not pollute the working medium, and have the advantages of small size, low noise, maintenance-free, and can run continuously for 24 hours, so micro vacuum pumps are widely used as power devices, widely used in gas sampling, gas circulation, vacuum adsorption, accelerated filtration, automobile vacuum assistance, etc., and have been widely used in medical, health, scientific research, environmental protection and other fields.
The biggest advantage of portable vacuum pump is simple installation, small size, stable output pressure, very high efficiency and long service life.
