QBY3-W Pneumatic Diaphragm Pump Decomposition Diagram:

working principle;
In the two symmetrical working chambers of the sanitary diaphragm pump, each is equipped with an elastic diaphragm. The connecting rod integrates the two diaphragms into one. Compressed air enters the valve chamber from the pump's inlet joint and pushes the diaphragm of working chamber B, driving the diaphragm connected by the connecting rod to move synchronously. At the same time, the gas inside the working chamber of A is discharged from the back of its diaphragm outside the pump. When the piston reaches the stroke point, the valve mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm pump in the opposite direction, thus forming synchronous reciprocating motion of the two diaphragms. Two one-way ball valves are installed in each working chamber, and the reciprocating motion of the diaphragm causes a change in the volume of the working chamber, driving the two one-way ball valves to alternately open and close, thereby enabling continuous suction and discharge of liquid.
The obvious difference between QBY3-W pneumatic diaphragm pump and other diaphragm pumps lies in the valve structure. The valve structure of QBY3-W pneumatic diaphragm pump eliminates the traditional "O" ring and cylindrical valve core structure. Adopting a three-phase pilot type eliminates the dead point of the distribution valve and the phenomenon of pump shutdown. Provided a reliable reversing device to avoid shutdown. This diaphragm pump has a larger flow rate and better conveying performance.
The QBY3-W pneumatic diaphragm pump has a simple design, reliable use, and long service life. All valve components can be replaced without disassembling the entire machine. All aluminum components are specially treated to be sturdy and durable in corrosive environments.
