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 inlet pressure should not exceed the maximum allowable pressure of the pump. Compressed air above the rated pressure may cause personal injury and property damage and damage the performance of the pump.
3. Ensure that the diaphragm pump pressure pipe system can withstand the highest output pressure to ensure that the drive air system cleaning and normal working conditions.
4. Electrostatic sparks may cause explosion and cause personal injury and property damage. If necessary, use a wire of sufficient cross-section to properly ground the grounding screw on the pump.
5. Grounding requirements in line with local laws and regulations and the requirements of the scene some of the special requirements of the provisions.
6. Tighten the diaphragm pump and the connection pipe joints, to prevent electrostatic vibration due to shock wipe. Use antistatic hose.
7. To periodically check and test the reliability of the grounding system, the grounding resistance is less than 100 ohms.
8. Maintain good ventilation and ventilation, away from flammable and heat sources.
9. Diaphragm pump exhaust may contain solids, do not put the exhaust port against the work area or people, so as to avoid personal injury.
10. When the diaphragm fails, the delivered material will be ejected from the exhaust muffler.
11. When transporting flammable and toxic fluids, keep the outlet in a safe place away from the work area.
12. Use at least 3/8 "ID OD tubing and muffler to smooth the tubing.
13. High fluid pressure can cause serious personal injury and property damage. Do not perform any maintenance work on the diaphragm pump and pipe system when the pump is pressurized. If the rotor pump needs to be repaired, cut off the pump first Gas, open the bypass pressure relief mechanism to make the piping system pressure relief, slowly loosen the connection of the pipe joints.
14. If the delivery of harmful toxic fluid pump, please do not send the pump directly to the factory to repair. Properly handle according to local laws and regulations, and use the pure fittings of Yangtze River Pump Company to ensure the service life.
15. Liquid Conveyor Parts Pumps made of aluminum alloy, which are not intended to be used for the transport of fluids containing Fe3 + and halogenated hydrocarbons and other halogenated hydrocarbon solvents, will cause corrosion which may cause the pump body to burst.
16. Ensure that all parts in contact with the transport body will not be corroded by the fluid being transported.
17. Ensure that all operators familiar with the operation and use of pump safety precautions, if necessary, the necessary protection supplies.
18. The correct use of the pump, do not allow long-term air operations.
