Pneumatic diaphragm metering pumps are widely used around our lives. The following Asian Fluid Network on how to choose the right pneumatic diaphragm metering pump, and the use of the process we need to pay attention to the details. Pneumatic diaphragm metering pump routine maintenance and simple maintenance methods, as follows: 1, to ensure that the maximum particles contained in the fluid does not exceed the pump maximum safety through the particle diameter standard; 2, intake pressure should not exceed the maximum allowable pneumatic diaphragm pump Use of compressed air at a pressure higher than the rated pressure may result in personal injury and property damage and damage to the performance of the pump. 3. Ensure that the pressurized piping system can withstand the highest output pressure achieved and that the drive air system is clean and normal Working conditions; 4, sparks may cause explosion caused by personal injury and property damage, as needed, use a large cross-sectional area of ​​the wire, the pump ground screw properly and reliably grounding; 5, grounding requirements in line with local laws and regulations and legal requirements Some of the special requirements of the regulations; 6, fastening the pneumatic diaphragm pump and the connection pipe joints, to prevent electrostatic vibration caused by the impact of sparks. The use of anti-static hose; 7, to periodically check and test the reliability of the grounding system, grounding resistance requirements of less than 100 ohms; 8, to maintain good exhaust and ventilation, away from flammable and heat sources; Exhaust may contain solids, not to the exhaust port against the work area or people, so as to avoid personal injury; 10, when the diaphragm failure, the delivery of materials will be ejected from the exhaust muffler; 11, to ensure that all operations Personnel are familiar with the operation and use of the pump to understand the safety precautions, if necessary, the necessary protection supplies; 12, please use at least three eighths of the inner diameter of the wall smooth pipe exhaust and muffler; 13, when the pneumatic diaphragm metering pump When transporting flammable and toxic fluids, place the outlet in a safe place away from the work area. 14. Do not send the pump directly to the manufacturer for repair if it is transported as a hazardous, toxic fluid pump. In accordance with local laws and regulations properly handle; 15, to ensure that all contact with the transport body parts will not be transported corrosive fluid damage; 16, the fluid pressure can cause serious personal injury and property damage, please do not pump pressure, Pump and material pipe system for any maintenance work, such as to be repaired, first cut off the pump intake, open the bypass pressure relief mechanism to relieve the pressure piping system, slowly loosen the connection of the pipe joints; 17, Liquid delivery part of the use of aluminum pneumatic diaphragm pumps, please do not use for the delivery of liquid containing Fe3 and halogenated hydrocarbons and other halogenated hydrocarbon solvents, it will produce corrosion caused by burst pump; 18, the proper use of pneumatic Diaphragm pump, do not allow long-term air operations. We are in the choice of pneumatic diaphragm metering pump according to actual needs, the use of occasions to consider, the details of the use must be given attention.
