Pneumatic diaphragm pump technical parameters Performance Profile QBY pneumatic diaphragm pumps can not only pump liquid but also transport some non-flowable media. There are many advantages of self-priming pump, submersible pump, shield pump, mud pump and impurity pump. Without filling the water, suction up to 7m, lift up to 70m, the outlet pressure â‰¥ 6kgf / cm2; Flow-spacious, with good performance, allowing up to 10mm diameter through the largest particles. Pumping mud, impurities, the pump wear little; Head, flow through the valve opening to achieve stepless adjustment (pressure regulation 1-7kgf / cm2); The pump without rotating parts, there is no shaft seal, the diaphragm will pump the moving parts of the pump and the workpiece media completely separated, the media will not be leaked out. Therefore, pumping toxic, easy to play or corrosive media, will not cause environmental pollution and endanger the integrity of people; Do not need electricity, safe and reliable in flammable and explosive places; Can be immersed in the medium to work; Easy to use, reliable work, just open and close the gas valve simply open and close, even if due to unexpected conditions and a long absence of medium-run or sudden shutdown, the pump will not be damaged, once overloaded, the pump will automatically shut down, With self-protection performance, when the load back to normal, but also automatically start running; The utility model has the advantages of simple structure and few wearing parts. The pump has the advantages of simple structure, convenient installation and maintenance, and the conveying medium of the pump can not contact the moving parts such as the valve, the connecting rod and the like, unlike the other type of pump due to the rotor, piston, gear, Wear and other parts of the performance and gradually decline; Can transport a more viscous liquid (viscosity of 10,000 centipoise); The pump without oil lubrication, even idling, the pump has no effect, which is a major feature of the pump. Â·working principle In the pump two symmetrical working chamber, each equipped with a diaphragm, the center link will be integrated into one. 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 â‘¢ outflow from the inlet, while the ball valve â‘ closed to prevent back flow, so that the cycle of the media continue to inhale from the entrance, the outlet discharge. Â·The main purpose 1. Pumping peanut butter, pickles, mashed potatoes, sausage, chocolate, hops, syrup, etc .; Pumping paint, paint, glue, adhesives; 3. Pumping all kinds of tiles, porcelain, brick and pottery glaze; 4. Pumping all kinds of abrasive, etchant, cleaning grease and so on; 5. pumping a variety of highly toxic, flammable, easy to play a liquid; Pumping all kinds of sewage, cement grouting and mortar; 7. Pumping all kinds of strong acid, alkali, strong corrosive liquids; 8. As a variety of solid-liquid separation equipment before the pressure transmission device.
