Diaphragm pump operation and precautions

Pneumatic diaphragm pump is a displacement pump with compressed air as the power and the volume change caused by the reciprocating deformation of the diaphragm, and its working principle is similar to that of the plunger pump. The use of pneumatic diaphragm pump operation should pay attention to the following points: 1, to ensure that the large particles contained in the fluid do not exceed the pump’s large safe through the particle diameter standard. 2, the intake pressure should not exceed the high allowable use pressure of the pump, higher than the rated pressure of compressed air may lead to personal injury and property loss and damage to the performance of the pump. 3, to ensure that the pump pressure of the pipeline system can withstand the achieved high output pressure, to ensure the drive gas system clean and normal working conditions. 4, electrostatic sparks may cause explosion resulting in personal injury and property loss, according to the need to use a large enough cross-sectional area of the wire, the grounding screw on the pump properly and reliably grounded. 5, grounding requirements comply with local laws and regulations and some special requirements of the site. 6. Tighten the pump and the connecting nozzle joints to prevent electrostatic sparks caused by vibration impact. Use an 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, maintain good exhaust and ventilation, away from flammable and explosive and heat sources. 9, the exhaust of the pump may contain solid objects, do not put the exhaust port against the working area or people, so as to avoid personal injury. 10, when the diaphragm fails, the conveying material will be expelled from the exhaust muffler. 11, when conveying 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 smooth inner wall pipe to connect the exhaust port and muffler. 13, the high pressure of the fluid may lead to serious personal injury and property damage, please do not perform any maintenance work on the pump and material pipe system when the pump is pressurized, if the rotor pump is to do maintenance, first cut off the pump intake, open the bypass pressure relief mechanism to relieve the pipeline system, and slowly loosen the connected pipe joints. 14, liquid transport part of the use of aluminum alloy material pump, please do not use to transport containing Fe3+ liquid and halogenated hydrocarbons and other halogenated hydrocarbon solvents, it will cause corrosion caused by the pump burst. 15, ensure that all parts in contact with the conveying body will not be corroded by the conveying fluid. 16, ensure that all operators familiar with the operation and use of the pump safe use precautions. 17, the correct use of the pump, does not allow a long period of empty operation.
