Fluorine lined QBY/QBK pneumatic diaphragm pump

1QBY/QBKtypepneumatic diaphragm pumpOverview:

1QBY3/QBY type pneumatic diaphragm pumpIt is a new third-generation diaphragm pump developed and produced by Jiujiang Pump Industry. This pump has the advantages of long service life, sufficient pressure, low noise, fine workmanship, and no pause. It can pump flowing liquids and transport some media that are not easy to flow. It has many advantages of conveying machinery such as submersible pumps, self-priming pumps, impurity pumps, shielded pumps, and mud pumps.

2. The main applications of QBY/QBK pneumatic diaphragm pumps are:

2QBY3/QBKtypepneumatic diaphragm pumpCharacteristics:

1. No need for water injection, with a suction height of up to 7 meters, a lift of 60 meters, and an outlet pressure of ≥ 6 bar

2. Spacious flow and good performance, allowing for a maximum particle diameter of up to 10 millimeters. When pumping mud and impurities, there is minimal wear on the pump;

3. The head and flow rate can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7 bar)

4. The pump has no rotating parts, shaft seals, diaphragms, etc. The medium pumped is completely separated from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. No need for electricity, safe and reliable to use in flammable and explosive places

6. Can work submerged in a medium

7. Easy to use, reliable in operation, with simple opening and closing of the gas valve for on-off operation. Even if the pump runs without medium for a long time or suddenly stops due to unexpected situations, it will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can automatically start and operate again;

8. The pump has a simple structure and few vulnerable parts. It is easy to install and maintain, and the medium transported by the pump does not come into contact with moving parts such as the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades;

9. Can transport viscous liquids (viscosity below 10000 centipoise);

10. This pump does not require oil lubrication, and even when idling, it has no impact on the pump, which is a major feature of this pump;

5. Working principle diagram and schematic diagram of QBY3/QBK pneumatic diaphragm pump:

1. QBY3/QBK Pneumatic Diaphragm PumpIn each of the two symmetrical chambers, there is an elastic diaphragm 6 installed. The connecting rod 7 integrates the two diaphragms into one. Compressed air enters the distribution valve 3 from the inlet joint 1 of the pump and pushes the diaphragms in the two working chambers, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from behind its diaphragm; Once the travel endpoint is reached, the valve mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm in the opposite direction, thus forming synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two one-way ball valves 4. The reciprocating motion of the diaphragm causes a change in the volume of the working chamber, forcing the two one-way ball valves to alternately open and close, thereby continuously sucking and discharging liquid.
