How to use pneumatic diaphragm pump： AODD pump is a positive displacement pump that uses compressed air as the power to change the volume through the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Pay attention to the following points when operating with pneumatic diaphragm pumps: 1. Ensure that the large particles contained in the fluid do not exceed the pump’s large particle diameter standards. 2. The intake pressure should not exceed the high allowable working pressure of the pump. Compressed air higher than the rated pressure may cause personal injury and property loss and damage the performance of the pump. 3. The piping system to ensure the pump pressure can withstand the high output pressure reached, and to ensure the cleanliness and normal working conditions of the driving air system. 4. Static sparks may cause explosions, resulting in personal injury, accidents, and property losses. Use a wire with a large enough cross-sectional area as needed to properly and reliably ground the ground screw on the pump. 5. Grounding requirements comply with local laws and regulations and some special requirements on site. 6. Fasten the pump and each connection pipe joint to prevent electrostatic sparks from being generated by vibration. Use antistatic hose. 7. To periodically check and test the reliability of the grounding system, the grounding resistance is required to be less than 100 ohms. 8. Keep good exhaust and ventilation, away from flammable, explosive and heat sources. 9. The exhaust of the pump may contain solids. Do not point the exhaust to the working area or people to avoid personal injury. 10. When the diaphragm fails, the conveyed materials will be ejected from the exhaust muffler. 11. When transporting flammable and toxic fluids, please connect the drain to a safe place away from the work area. 12. Please use at least 3/8" inner diameter pipe with smooth inner wall to connect the exhaust port and the muffler. 13. The high pressure of the fluid may cause serious personal injury and property damage. Please do not perform any maintenance on the pump and the material pipe system when the pump is pressurized. For maintenance, first cut off the pump air intake and open The bypass pressure relief mechanism relieves the pressure of the pipeline system and slowly loosens the connected pipe joints. 14. Please do not send the pump directly to the manufacturer for repair if the pump is for transporting hazardous and toxic fluids. Properly dispose of it in accordance with local laws and regulations, and use Shanghai Jinggang Pumps' genuine accessories to ensure service life. 15. Pumps made of aluminum alloy are used in the liquid transportation part. Please do not use them to transport liquids containing Fe3+, halogenated hydrocarbons and other halogenated hydrocarbon solvents, which will cause corrosion and cause the pump body to burst. 16. Ensure that all parts contacting the conveying body will not be corroded and damaged by the conveyed fluid. 17. Ensure that all operators are familiar with the operation and use of the pump and master the safety precautions of the pump. If necessary, provide the necessary protective equipment. 18. Use the pump correctly and do not allow long-term dry running.
