Attention, foreign trade personnel exporting rolling diaphragms! The shapes of the shell include three or four layers, aluminum alloy, cast iron, stainless steel, Hastelloy alloy, polypropylene, polyvinylidene fluoride diaphragm, food rubber, and polytetrafluoroethylene diaphragm.
The full name of diaphragm pump is diaphragm pump, which connects compressed air, light water or oil, is lined with liquid, and there are screws and aluminum alloy diaphragms between the lined diaphragm pump and the diaphragm pump, making it very sturdy!
Diaphragm pump, also known as diaphragm pump, connects compressed air, suction and air compressor subsidiaries, microcontrollers, and diaphragm pumps. The diaphragm pump uses compressed air, nitrogen, or natural gas as the power source. The main directional (pneumatic) control valve distributes compressed air to the gas chamber and applies uniform pressure to the inner surface of the diaphragm. The gas discharged at the same time is discharged from the rear of the other side of the pump through the guide port of the gas valve assembly. The gas pressure in the inner chamber of the pneumatic double diaphragm pump exceeds the liquid chamber pressure, and the diaphragm connecting rod moves back and forth to discharge on one side and inhale on the other side. The direction of liquid discharge and suction is controlled by the direction of the check valve (ball valve or disc valve). When the suction stroke is based on the inlet pressure, the connection method should be around or on the pipeline. The suction stroke also requires adjusting the outlet air source pressure to adjust the flow rate or adjust the flow rate.
QBY3 pneumatic diaphragm pump models: QBY-50 (Q), QBK-40 (NG), QBK-50 (aluminum plate, elevator).
QBY pneumatic diaphragm pump is currently the most innovative pump in China. It can pump and absorb various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. The flow passage components of the pump body are made of stainless steel, aluminum alloy, cast iron, and engineering plastic. The diaphragm is made of nitrile rubber, fluororubber, chloroprene rubber, polytetrafluoroethylene, and perfluoroethylene propylene (F46) according to different liquids.
No need for irrigation and water diversion, with a suction head of up to 7m, a lift of 50m, and an outlet pressure of ≥ 6kgf/cm2;
The flow is spacious and the passing performance is good, allowing the maximum particle diameter to reach 10mm. When pumping mud and impurities, there is minimal wear on the pump;
The head and flow rate can be adjusted steplessly through the opening of the air valve (the air pressure can be adjusted between 1-7kg/cm2).
Convenient to use, reliable in operation, and easy to open and close gas valves for start and stop. Even if there is no medium operation for a long time or sudden shutdown due to unexpected circumstances, the pump will not be damaged. Overload pumps will automatically stop, with self-protection performance. When the load returns to normal, they can automatically start and run;
The pump has a simple structure and fewer vulnerable parts. It is easy to install and maintain, and the medium conveyed by the pump will not come into contact with moving parts such as the distribution valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of rotors, pistons, gears, blades, and other components;
Double diaphragm pumps do not require oil lubrication, and even with empty rotors, water, or compressors, they have convenient application and maintenance. The phenomenon of water entering the water tank is not like other types of pumps, where the performance gradually decreases due to wear and tear of components such as rotors, pistons, and valve stems;
Pneumatic diaphragm pumps can transport a wide range of fluids, from low viscosity to high viscosity, and from corrosiveness to viscosity.
