QBK Series Air Operated Diaphragm Pump

QBY pneumatic diaphragm pump product overview: QBY3 third generation pneumatic diaphragm pump produced by our company is a new type of conveying equipment and a new type of pump in China at present. Using compressed air as the power source, it can absorb all kinds of corrosive liquid, liquid with particles, high viscosity, volatile and flammable liquid.

QBY pneumatic diaphragm pump features: The difference between QBY3 series third generation pneumatic diaphragm pump and traditional diaphragm pump lies in the valve structure. QBY3 series pneumatic diaphragm pump valve structure eliminates the traditional "O" ring and column valve structure of the valve. Three way pilot type is adopted to eliminate valve sticking point and pump shutdown. The correct reversing signal is provided to avoid stop and change direction more quickly, so that the pump has a large flow rate and provides the conveying performance, so that the pulse is small and the flow is stable. QBY3 third generation pneumatic diaphragm pump is designed with simple air reversing valve, which can avoid expensive shutdown cost caused by shutdown. The air valve components can be replaced without removing the fluid part. After other treatment, the aluminum parts can resist the corrosion caused by unclean air. The slide block made of plastic material in the reversing valve is solid and durable, and is not easy to be damaged. The smooth air path and flexible reversing are realized.

Working principle of QBY pneumatic diaphragm pump In the two symmetrical working chambers of diaphragm pump, there is a piece of elastic diaphragm respectively, and the connecting rod will form two diaphragms into one. After the compressed air enters the air valve chamber from the air inlet connector of the pump, it pushes the diaphragm in a working chamber and drives the diaphragm connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of its diaphragm. When the piston reaches the end of stroke, the valve mechanism will automatically introduce compressed air into another working chamber to push the diaphragm pump to move in the opposite direction, thus forming the synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two ball valves. The reciprocating motion of diaphragm causes the change of volume in the working chamber, forcing the two ball valves to open and close alternately, so that the liquid can be continuously inhaled and discharged.
