It is suitable for conveying various corrosive and particle-containing liquids, as well as high-viscosity, volatile, flammable, and highly toxic liquids.<\/p>\n<p><strong>Working principle<\/strong><\/p>\n<p>In the two symmetrical working chambers of the pump, each is equipped with an elastic diaphragm, and the connecting rod connects the two diaphragms into one. After the compressed air enters the air distribution valve from the air inlet joint of the pump, it pushes the diaphragms in the two working chambers to move, 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 from the back of its diaphragm. Once it reaches the end of the stroke, the air distribution mechanism automatically introduces compressed air into the other working chamber, pushing the diaphragm to move in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Two one-way ball valves are set in each working chamber. The reciprocating motion of the diaphragm causes the volume of the working chamber to change, forcing the two one-way ball valves to open and close alternately, thereby continuously sucking and discharging the liquid.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-1329 size-medium\" title=\".jpg\" src=\"https:\/\/www.tflequip.com\/wp-content\/uploads\/2024\/09\/-e1726216829148-267x300.jpg\" alt=\".jpg\" width=\"267\" height=\"300\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Performance of pneumatic diaphragm pump<\/strong><\/p>\n<p>(1) No need to fill water, suction distance up to 7 m, head up to 50 m, outlet pressure \u22656kg f\/cm\u00b2.<\/p>\n<p>(2) Good flow performance, allowing the maximum particle diameter to pass through up to 10 mm. When pumping mud and impurities, there is little wear on the pump.<\/p>\n<p>(3) The head and flow rate can be adjusted steplessly through the air valve opening (the air pressure is adjusted between 1 and 7kgf\/cm\u00b2).<\/p>\n<p>(4) The pump has no rotating parts and no shaft seal. It relies on the reciprocating motion of a pair of diaphragms to pump various media. Because the moving parts of the pump and the working medium are completely separated, the transported medium will not leak out, avoiding environmental pollution and personal injury.<\/p>\n<p>(5) It does not use power supply and can be used in flammable and explosive places, which is safe and reliable.<\/p>\n<p>(6) It can be immersed in the medium instead of a submersible pump to pump liquid.<\/p>\n<p>(7) When starting and stopping the pump, you only need to open and close the gas valve to operate. Even if there is no medium pumping for a long time or the pump suddenly stops due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically shut down and has self-protection capabilities. When the load returns to normal, it can automatically start running again.<br \/>\n(8) Simple structure and few vulnerable parts. The diaphragm pump has a simple structure and is easy to install and maintain. When the pump conveys the medium, it will not contact the moving parts such as the gas distribution valve and connecting rod, avoiding corrosion and wear of the parts.<br \/>\n(9) It can convey relatively viscous liquids.<br \/>\n(10) No oil lubrication is used, and even idling will not have any effect on the pump.<\/p>\n<p><strong>Scope of application<\/strong><\/p>\n<p>(1) Cleaning the bottom of tanks and tanks: The diaphragm pump can be used to pump and suck the medium at the bottom of the tank and tank.<\/p>\n<p>(2) Temporary tank emptying: Using a diaphragm pump to connect a temporary pipeline can quickly and conveniently complete the temporary tank emptying and transportation work.<\/p>\n<p>(3) Removal of water from wells and ditches: The diaphragm pump can quickly remove water and dirty liquid when repairing wells and ditches, avoiding the inconvenience caused by being far away from the power supply.<\/p>\n<p>(4) Cleaning and processing sludge: Diaphragm pumps are flexible and convenient in processing sludge in sewage treatment plants.<\/p>\n<p>(5) Suitable for conveying media in hazardous areas: Diaphragm pumps are safe and reliable when removing media in fireproof and explosion-proof areas.<\/p>\n<p>(6) Can be immersed in liquid for use: The pump is immersed in liquid, and compressed air is led out using a hose, which can replace a submersible pump.<\/p>\n<p><strong>General advantages of pneumatic diaphragm pumps<\/strong><\/p>\n<p>(1) No electric sparks, can run dry, can start self-priming, no complex control is required, simple to operate, and the self-priming height can reach 6 m.<\/p>\n<p>(2) The materials of the pump body and diaphragm can be selected to convey media such as strong acids, strong alkalis, organic solvents, etc. with different characteristics.<\/p>\n<p>(3) No dynamic seal, no contamination of materials, and not easy to damage the properties of materials.<\/p>\n<p>(4) No rotating parts (or bearings), no mechanical shaft seals, no connectors, and low maintenance costs.<\/p>\n<p>(5) Change the conveying speed by changing the gas volume.<\/p>\n<p>(6) Change the conveying height by changing the pressure.<\/p>\n<p>(7) The outlet can be opened and closed at any time without worrying about blockage.<\/p>\n<p>(8) The pressure is automatically balanced (no pressure relief valve is required).<\/p>","protected":false},"excerpt":{"rendered":"<p>The pneumatic diaphragm pump uses compressed air as the power source, and uses the diaphragm of the cylinder to agitate back and forth to achieve the purpose of conveying various media.
