WZ-3B-type micro-pump is designed for our new generation of portable hand-held vacuum pump. In addition to the shape, all of the vacuum pump instead of the traditional desktop inhalator. It preserves the advantages of the company's other models of vacuum equipment, and low price, appearance, easy to carry, the reservoir bottle can be pasteurized and is equipped with an overflow device. Can be used in the laboratory aspiration, vacuum and so on. Good price is definitely your first choice lab. WZ-3B type of micro-pump works: the circular motion of the motor by mechanical means inside the pump diaphragm to do the reciprocating motion, thereby fixing the volume of air in the pump chamber is compressed, stretched to form a vacuum (negative pressure), at the exhaust port of the pump a pressure difference with the external atmospheric pressure, under a pressure difference, the gas pressure (suction) into the pump chamber, and then discharged from the exhaust port. A closed container (at the start of the internal atmospheric pressure 100KPa), connected to the micro-pump, it continuous pumping, the final gas pressure in a closed vessel will be lower than the atmospheric pressure, to reach an absolute pressure of 60KPa. Not only that, through a special technical improvements, in addition to a single miniature vacuum pump exhaust, but also can be formed dual exhaust cheer miniature vacuum pump (ie the exhaust side can produce relatively large positive pressure) for pressurized, inflatable, to overcome the system resistance, etc., and a very unique dual micro-pump water vapor, which can be used to require long-term idling, dry transfer and so on occasion, unlike most of the pumps idle, or run dry will damage the pump. Because of the mouth or pumping exhaust vent can be formed with the outside atmospheric pressure difference, but unlike the large vacuum pump and vacuum pumps require lubricating oil, does not pollute the working medium, but also has small size, low noise, maintenance-free, continuous 24 hours of operation, etc., so the micro-pump is used as power plant, widely used in gas sampling, gas circulation, vacuum, acceleration filtering, auto vacuum booster and so on occasion, in the medical, health, scientific research, environmental protection and other fields has been widely applied .
