Pneumatic diaphragm pump is a compressed air-powered, through the diaphragm reciprocating deformation volume changes caused by the volume of the pump, the working principle is similar to the piston pump. When using the pneumatic diaphragm pump to operate the operation should pay attention to the following points: 1. To ensure that the maximum particles contained in the fluid does not exceed the maximum safety of the pump through the particle diameter standard. 2. The intake pressure does not exceed the maximum allowable pressure of the pump, Compressed air at rated pressure may cause personal injury and property damage and damage pump performance. 3. Ensure that the diaphragm pump pressure piping system can withstand the maximum output pressure achieved to ensure that the drive air system clean and normal working conditions. 4. Sparks may cause explosions lead to personal injury and property damage, according to the need to use enough A large cross-sectional area of ​​the wire, the pump ground screw properly and reliably grounded. 5. Grounding requirements in line with local laws and regulations and the requirements of the scene some of the special requirements of the provisions. 6. Tighten the diaphragm pump and the connection pipe joints, to prevent electrostatic vibration due to shock wipe. Use antistatic hose. 7. To periodically check and test the reliability of the grounding system, the grounding resistance is less than 100 ohms. 8. Maintain good ventilation and ventilation, away from flammable and heat sources. 9. Diaphragm pump exhaust may contain solids, do not put the exhaust port against the work area or people, so as to avoid personal injury. 10. When the diaphragm fails, the delivered material will be ejected from the exhaust muffler. 11. When transporting flammable and toxic fluids, always place the outlet in a safe place away from the work area. 12. Use at least 3/8 "inner diameter smooth tubing to connect exhaust vent and muffler 13. High fluid pressure can cause serious personal injury and property damage. Do not apply pressure to the diaphragm pump Pipe system for any maintenance work, the rotor pump to be repaired, first cut off the pump intake, open the bypass pressure relief mechanism to relieve pressure pipeline system, slowly loosen the connection of the pipe joints. Please do not send the pump directly to the manufacturer for repair, properly handle according to local laws and regulations, and use the pure parts of the Yangtze River Pump Co., Ltd. to ensure the service life. 15. The liquid conveying part is made of aluminum alloy pump, Do not use it to transport fluids containing Fe3 + and halogenated hydrocarbons and other halogenated hydrocarbon solvents, corrosion of the pump body will result in bursting of the pump body. 16. Ensure that all parts that come into contact with the delivery body are not corroded by the fluid being transported . 17. Ensure that all operators are familiar with the operation and use of pump safety precautions, if necessary, with the necessary protective equipment. 18. Correct use of the pump It does not allow prolonged idling.
