Precautions when operating pneumatic diaphragm pump
Pneumatic diaphragm 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 using pneumatic diaphragm pumps:
1. Ensure that the largest particle contained in the fluid does not exceed the maximum safe passing particle diameter standard of the pump.
2. The intake pressure should not exceed the maximum 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. Ensure that the pump pressure piping system can withstand the highest output pressure reached, and ensure the clean and normal working conditions of the driving air system.
4. Electrostatic sparks may cause explosions and cause personal injury and death accidents and property losses. If necessary, use a wire with a large enough cross-sectional area 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. Tighten the pump and all connecting pipe joints to prevent electrostatic sparks from being generated by vibration and impact. 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 outlet 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 harmful and toxic fluids. Properly dispose of it in accordance with local laws and regulations, and use genuine parts from Shanghai Wangquan Pump Company to ensure service life.
15. Pumps using aluminum alloy materials for 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 for the use of the pump. If necessary, provide necessary protective equipment.
18. Use the pump correctly and do not allow long-term dry operation.
