Is there a single phase powered vacuum pump

Yes, a 12V vacuum pump is generally referred to as being powered by DC 12V. It is also known as a miniature DC vacuum pump. Miniature DC vacuum pump is also used 5V, 24V power supply. 12V vacuum pump or 24V DC vacuum pump is very small, so it is called micro vacuum pump. Micro DC vacuum pump is mainly the use of the motor's circular motion, through the mechanical device to make the pump internal diaphragm reciprocating movement, so that the fixed volume of the pump chamber of the air compression, stretching the formation of a vacuum (negative pressure), in the pump pump pumping port with the external atmospheric pressure pressure to produce a pressure difference in the pressure difference under the action of the gas will be pressed (suction) into the pump chamber, and then discharged from the exhaust port.

There is also a single-phase direct-connected rotary vane vacuum pump, which is used to pump out gas from sealed containers as basic equipment. It can be used alone, can also be used for booster pumps, diffusion pumps, molecular pumps, pumps, maintenance pumps, titanium pumps pre-pumping pumps; can be used for electric vacuum container manufacturing, vacuum welding, printing, photographic plate, food packaging, vacuum vacuum blisters, refrigeration equipment maintenance and instrumentation, instrumentation equipment supporting and laboratories and so on. Widely used in aerospace, semiconductor, coating, food packaging, drying, refrigeration, scientific research, medical, electronics, chemical, pharmaceutical and other professional units and colleges and universities and other departments of the laboratory, laboratory.
