QBY series pneumatic diaphragm pump works
QBY series of pneumatic diaphragm pump is a new type of conveying machinery, is currently the most novel kind of pump. The use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted. Diaphragm pump according to different liquid medium were nitrile rubber, neoprene, fluorine rubber, PTFE. Working principle: Two symmetrical working chambers of the diaphragm pump are respectively equipped with a flexible diaphragm 6, the connecting rod is integrated with two diaphragms, the compressed air enters into the valve 3 through the inlet connector 1 of the pump, Promote the two working chamber diaphragm, drive the two rods connected to the joint rod synchronized movement. At the same time, the gas in the other working chamber is drained from the back of the diaphragm out of the pump. Once you reach the end of the itinerary. The air distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Two one-way ball valves 4 are provided in each working chamber, the reciprocating movement of the diaphragm causing a change in the volume of the working chamber, forcing the two one-way ball valves to alternately open and close, thereby continuously drawing and discharging the liquid.
