A pneumatic diaphragm pump is a positive displacement pump that uses compressed air as power and creates volume changes through the reciprocating deformation of a diaphragm. Its working principle is similar to that of a plunger pump.
When operating a pneumatic diaphragm pump, the following points should be noted:
Ensure that the largest particle in the fluid does not exceed the pump's maximum safe particle diameter standard.
Do not exceed the pump's maximum permissible operating pressure. Compressed air exceeding the rated pressure may cause personal injury, property damage, and impair pump performance.
Ensure that the pump's piping system can withstand the maximum output pressure. Ensure the cleanliness and normal operating conditions of the drive air system.
Static sparks may cause explosions, resulting in personal injury and property damage. Use a conductor with a sufficiently large cross-sectional area as needed and ensure the pump's grounding screw is properly and reliably grounded.
Grounding requirements must comply with local regulations and any special site requirements.
Tighten the pump and all connecting pipe joints securely to prevent static sparks generated by vibration, impact, or friction. Use anti-static hoses.
Periodically check and test the reliability of the grounding system. The grounding resistance should be less than 100 ohms.
Maintain good ventilation and keep away from flammable, explosive and heat sources.
