QBK-W Sanitary Pneumatic Diaphragm Pump

QBK-W Sanitary Pneumatic Diaphragm PumpWorking Principle:
In the two symmetrical working chambers of the sanitary diaphragm pump, there is an elastic diaphragm installed in each chamber. The connecting rod integrates the two diaphragms into one. Compressed air enters the air valve chamber from the pump's inlet joint and pushes the diaphragms of the two B working chambers, driving the diaphragms 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 outside the pump. When the piston reaches the key 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. It is feared that the two one-way ball valves will alternately open and close, allowing for continuous suction and discharge of liquid.
QBK-W Pneumatic Diaphragm PumpThe obvious difference from other diaphragm pumps lies in the valve structure. The valve structure of QBY-W pneumatic diaphragm pump eliminates the traditional "O" ring and cylindrical valve structure of the distribution valve. Adopting a three-phase pilot type eliminates valve dead center and pump shutdown phenomena. Providing correct and reliable directional signals to avoid shutdown and faster directional changes allows the pump to have a larger flow rate, resulting in smaller pulses and more stable flow performance.
The QBK-W pneumatic diaphragm pump has a simple and highly reliable air reversing design, which can ensure uninterrupted operation without incurring safety related parking costs. All air valve components can be replaced without disassembling the flow part. Aluminum components, after special treatment, can be replaced to prevent corrosion caused by unclean air. The plastic slider in the directional valve is sturdy and durable.
