Pump pump refers to have one in and one exhaust nozzle, and can continuously form a vacuum or negative pressure at the inlet, exhaust nozzle to form a micro positive pressure working medium is mainly a gas instrument, often called micro pumping pump, micro vacuum pump. The working principle of the pump is the motor to do the circular movement, through the mechanical device to make the pump internal diaphragm reciprocating motion, thus the fixed volume of the pump chamber air compression, stretching to form a vacuum, in the pump outlet and the external atmospheric pressure difference, under the action of the pressure difference, the gas into the pump cavity, and then discharged from the exhaust port. Because the exhaust outlet or exhaust outlet can form with external atmospheric pressure difference, at the same time unlike large vacuum pump need lubricating oil and vacuum pump, will not pollute the working medium, and has a small volume, low noise, maintenance free, can run 24 hours, so the micro vacuum pump is used as a power plant, in environmental protection, scientific research and other fields has been widely used.
Characteristics of pumping pump:
1. With heat switch and power supply insurance, simple operation;
2. Compact design, easy to carry, and do not occupy space;
3. Can work 24 hours continuously, oil-free, 100% maintenance-free;
4. Small microvibration noise;
5. Organic solvents or acid-alkaline gases can be extracted.
