pneumatic diaphragm pump

1、 Working principle:pneumatic diaphragm pumpWorking principle: In the two symmetrical working chambers of the diaphragm pump, there is an elastic diaphragm installed in each chamber. The connecting rod integrates the two diaphragms, and compressed air enters the intermediate body from the pump's inlet joint, pushing the diaphragms in the two working chambers and driving 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 outside the pump. When the piston reaches the end of its stroke, 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, forcing the two one-way ball valves to alternately open and close, thereby enabling continuous suction and discharge of liquid.pneumatic diaphragm pumpThe difference from other diaphragm pumps lies in the valve structure.pneumatic diaphragm pumpThe valve structure eliminates the traditional one“O”A distribution valve with a circular and cylindrical valve structure. Adopting a three-way 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, providing delivery performance for smaller pulses and more stable flow.pneumatic diaphragm pumpA simple and highly reliable air directional valve design can ensure high downtime costs without shutting down. All air valve components can be replaced without disassembling the fluid part. Aluminum components, after special treatment, can resist corrosion caused by unclean air. The plastic slider in the directional valve is sturdy and durable, not easily damaged, does not require lubrication, and ensures smooth air flow and flexible directional change.

IIIPerformance Overview:pneumatic diaphragm pumpIt can pump flowing liquids and dry powders, as well as transport some non flowing media, and has many advantages of conveying machinery such as self-priming pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps.1. No need for irrigation, with a suction range of up to7mThe lift reaches80mExport pressure ≥0.8MPa；2. Spacious and flowing, with good performance, allowing for smooth passageParticle diameter up to9.4mmWhen pumping mud and impurities, there is minimal wear on the pump;3. The head and flow rate can be adjusted by the pressure of the gas source0.1~0.84MPaBetween);4. Scope of work environment:5～65℃；5. The pump has no rotating parts and no shaft seal. The diaphragm separates the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak to outsiders. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety;6. No need for electricity, safe and reliable to use in flammable and explosive places;7. Can work submerged in a medium;8. Easy to use, reliable in operation, and with simple opening and closing of the gas valve, the pump will not be damaged even if it runs for a long time without medium or suddenly stops due to unexpected situations. one
Once overloaded, the pump will automatically shut down, with self-protection performance. When the load returns to normal, it can automatically start and run again.9. Simple structure and few vulnerable parts. The pump has a simple structure and is easy to install and maintain. The medium conveyed by the pump will not come into contact with moving parts such as the valve and connecting rod, unlike other types of pumps where performance gradually decreases due to wear of components such as rotors, pistons, gears, and blades;10. Can transport viscous liquids; The viscosity is10000 Below centipoise)11. This pump does not require lubricating oil and has no impact on the pump even when idling. This is a major feature of the pump.
