Pneumatic Diaphragm Pump Technical Parameters · Performance Introduction QBY pneumatic diaphragm pump can not only pump liquid but also transport some difficult to flow medium, with self-priming pump, submersible pump, shield pump, mud pump and impurity pump and other transportation machinery, many advantages . Needless irrigation, suction up to 7m, lift up to 70m, outlet pressure ≥ 6kgf / cm2; flow spacious, through the good performance, allowing the largest diameter of 10mm. Pumping slurry, impurities, the pump wear is minimal; head, flow through the valve opening to achieve stepless regulation (pressure regulator 1-7kgf / cm2); the pump without rotating parts, there is no shaft seal, the diaphragm will be pumping Of the media and pump moving parts, the workpiece media completely separated, the media will not be delivered to the outside leakage. So pumping toxic, easy to play or corrosive media, will not cause environmental pollution and endanger the integrity of people; do not have electricity, safe and reliable use in flammable and explosive places; can be immersed in the media work; easy to use, reliable, Just open and close the gas valve simply by opening and closing the gas valve. The pump will not be damaged even if there is no medium running or sudden shutdown due to accidental conditions. The pump will shut down automatically with self-protection when overloaded. The load is restored to normal, but also automatically start running; simple structure, less wearing parts, the pump structure is simple, easy installation, maintenance, pump delivery of media will not come into contact with the valve, connecting rod and other moving parts, unlike other Type of pump due to rotor, piston, gear, blades and other parts of the wear and tear and gradually decline in performance; can deliver a more viscous liquid (viscosity at 10,000 centipoise); The pump without oil lubrication, even idling, the pump is also Without any impact, this pump is a major feature. · Working principle In the two symmetrical working chambers of the pump, each is equipped with a diaphragm, which is integrated by the central link. Compressed air from the pump inlet into the valve, through the valve mechanism to introduce compressed air into one of the chamber to promote movement of the diaphragm in the chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison. In the figure, the compressed air enters into the distribution valve to move the diaphragm to the right, then the suction of the chamber causes the medium to flow in from the entrance, push the ball valve (2) into the chamber, and the ball valve (4) is closed due to inhalation; the medium in the chamber Squeeze, push the ball valve ③ outflow from the inlet, while the ball valve ①closed to prevent back flow, so that the cycle of the media continue to inhale from the entrance, the outlet discharge. · The main purpose 1. Pumping peanut butter, pickles, mashed potatoes, sausage, chocolate, hops, syrup, etc .; 2. Pump paint, paint, glue, adhesives; And pottery glaze; 4. Pumping all kinds of abrasive, etchant, cleaning grease and so on; 5. Pumped a variety of highly toxic, flammable, easy to play a liquid, etc .; 6. Pumping all kinds of sewage, cement grouting and mortar ; 7. Pumping all kinds of strong acid, alkali, strong corrosive liquids, etc .; 8. As a variety of solid-liquid separation equipment before the pressure transmission device.
