Pneumatic diaphragm pump is a displacement pump powered by compressed air, which causes a change in volume through the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Pneumatic diaphragm pumps can be used according to certain principles and methods, and in specific operating procedures, they can be used according to certain instructions and precautions, which can produce important usage effects and contributions, and play a good value in use. When operating a pneumatic diaphragm pump, the following points should be noted: ensure that the maximum particles contained in the fluid do not exceed the maximum safe passing particle diameter standard of the pump. Tighten the pump and all connecting pipe joints to prevent static sparks from being generated by vibration, impact, and friction of the middle opening pump. Use anti-static hoses. To periodically check and test the reliability of the grounding system, it is required that the grounding resistance be less than 100 ohms. Maintain good exhaust and ventilation, and stay away from flammable, explosive, and heat sources. The intake pressure should not exceed the maximum allowable operating pressure of the pump. Compressed air above the rated pressure of the pipeline pump may cause personal injury, property damage, and damage to the pump's performance.
Static sparks may cause explosions, resulting in personal injury accidents and property damage. Use wires with sufficient cross-sectional area as needed to properly and reliably ground the grounding screws on the pump. The grounding requirements comply with local laws and regulations, as well as some special requirements on site. The exhaust of the pump may contain solid substances. Do not point the exhaust port towards the work area or people to avoid personal injury. When the diaphragm fails, the material conveyed by the sewage pump will be sprayed out from the exhaust muffler. Ensure that the pipeline system for pump pressure can withstand the maximum output pressure achieved, and guarantee the cleanliness and normal working conditions of the multi-stage pump driven pneumatic system. When transporting flammable and toxic fluids, please connect the discharge outlet to a safe location away from the work area. Please use a pipe with at least 3/8 'inner diameter and smooth inner wall to connect the exhaust port and muffler.
The high pressure of the fluid may cause serious personal injury and property damage. Please do not perform any maintenance work on the pump and material pipe system when pressurizing the pump. If the rotary pump needs to be repaired, first cut off the intake of the pump, open the bypass pressure relief mechanism to relieve the pressure of the pipeline system, and slowly loosen the connected pipeline joints. If harmful and toxic fluid pumps are being transported, please do not send the pump directly to the manufacturer for repair. Pumps made of aluminum alloy materials for liquid transportation should not be used to transport liquids containing Fe3+, halogenated hydrocarbons, or other halogenated hydrocarbon solvents, as this may cause corrosion and result in pump body rupture. Ensure that all components in contact with the conveying body are not corroded or damaged by the fluid being conveyed. Ensure that all operators are familiar with the operation and safe use of the pump, and if necessary, provide necessary protective equipment. Correctly use the pump and do not allow prolonged idle operation.
