Pneumatic Diaphragm Pump Application Notice
The pneumatic diaphragm pump is a volumetric 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 the plunger pump. The pneumatic diaphragm pump is used according to certain principles and methods. It can be used according to certain instructions and precautions in the specific operating procedures, which can produce important use effects and contributions, and exert good use value. Pay attention to the following points when operating with a pneumatic diaphragm pump: ensure that the maximum particles contained in the fluid do not exceed the maximum safe passage of the pump through the particle diameter standard. Tighten the pump and each connecting pipe joint to prevent the medium-opening pump from generating static sparks due to vibration shock. Use an antistatic hose. To periodically check and test the reliability of the grounding system, the grounding resistance is required to be less than 100 ohms. Maintain good exhaust and ventilation, 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 pump may cause personal injury and property damage and damage to the performance of the pump.
Static sparks may cause explosions and personal injury and property damage. Use wires with a large cross-sectional area as needed to properly ground the grounding screws on the pump. The grounding requirements are in accordance with local laws and regulations and some special requirements on site. The exhaust of the pump may contain solid objects. Do not point the exhaust port to the work area or people to avoid personal injury. When the diaphragm fails, the material delivered by the sewage pump is ejected from the exhaust muffler. The piping system that guarantees the pump pressure can withstand the highest output pressure achieved, ensuring the clean and normal working conditions of the multistage pump-driven pneumatic system. When transporting flammable and toxic fluids, connect the vents to a safe place away from the work area. Use a pipe with a smooth inner wall of at least 3/8″ inner diameter to connect the vent and muffler.
The high pressure of the fluid may cause serious personal injury and property damage. Please do not carry out any maintenance work on the pump and the pipe system when the pump is pressurized. When the rotor pump is to be repaired, first cut off the intake air of the pump and open it. The bypass pressure relief mechanism relieves the piping system and slowly loosens the connected pipe joints. If the pump is a harmful toxic fluid pump, please do not send the pump directly to the factory for repair. Pumps using aluminum alloy in the liquid conveying part should not be used to transport liquids containing Fe3+ and halogenated hydrocarbons and other halogenated hydrocarbon solvents, which will cause corrosion and cause the pump to burst. Ensure that all parts that come into contact with the conveyor are not damaged by the corrosive fluids being transported. Ensure that all operators are familiar with the operation and use of the safe use of the pump, if necessary, with the necessary protective equipment. Proper use of the pump does not allow long periods of idle running.
