Pneumatic diaphragm pump is a compressed air-powered, through the diaphragm reciprocating deformation volume changes caused by the volume of the pump, the working principle is similar to the piston pump. The use of pneumatic diaphragm pump operation should pay attention to the following points: 1, to ensure that the maximum particles contained in the fluid does not exceed the maximum safety of the pump through the particle diameter standard. 2, the intake pressure Do not exceed the maximum allowable pressure pump, compressed air above the rated pressure may result in personal injury and property damage and damage the performance of the pump. 3, to ensure that the pump pressure piping system can withstand the highest output pressure to ensure that the drive air system clean and normal working conditions. 4. Electrostatic sparks may cause personal injury and property damage due to explosion. Use wires with enough large cross-section to properly ground the grounding screws on the pump. 5, grounding requirements in line with local laws and regulations and site requirements of some special requirements. 6, fasten the pump and the connection pipe joints to prevent electrostatic sparks due to vibration impact. Use antistatic 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. 9, the pump exhaust may contain solids, do not face the work area or exhaust port, so as to avoid personal injury. 10, when the diaphragm failure, the delivery of materials from the exhaust muffler squirting. 11, When transporting 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 wall pipe connection exhaust and muffler. 13, high fluid pressure may cause serious personal injury and property damage, please do not pump the pressure and the pump System to carry out 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. Toxic fluid pump, please do not pump directly to the manufacturer to repair. Properly handled according to local laws and regulations and the use of genuine accessories Shanghai Wang Quan Pump Company to ensure that the service life. 15, the liquid transfer part of the use of aluminum alloy pump, please Do not be used to transport liquids containing fe3 + and halogenated hydrocarbons and other halogenated hydrocarbon solvents, corrosion will cause the pump body burst. 16, to ensure that all contact with the transport body parts will not be transported fluid corrosive damage. 17, to ensure that all operators are familiar with the operation and use of pump safety precautions, if necessary, to provide the necessary protection 18, the proper use of the pump, do not allow empty running long.
