Precautions for operation of pneumatic diaphragm pump

Date of issue:[2020-08-17]     Click through rate:    

Precautions for operation of pneumatic diaphragm pump:

1. Ensure that the maximum particles contained in the fluid do not exceed the maximum safe passing particle diameter standard of the pump.

2. The inlet pressure should not exceed the maximum allowable working pressure of the pump. Compressed air higher than the rated pressure may cause personal injury, property loss and damage to the pump performance.

3. Ensure that the pipeline system of pump pressure can bear the maximum output pressure, and ensure the clean and normal working conditions of driving gas system.

4. Electrostatic spark may cause explosion, resulting in personal injury and property loss. According to the need, use enough large cross-sectional area wire to properly and reliably ground the grounding screw on the pump.

5. The grounding requirements shall comply with local laws and regulations and some special requirements on site.

6. Fasten the pump and all connecting pipe joints to prevent electrostatic spark due to vibration impact. Use antistatic hose.

7. To check and test the reliability of the grounding system periodically, the grounding resistance should be less than 100 ohm.

8. Keep good exhaust and ventilation, keep away from inflammable, explosive and heat sources.

9. The exhaust of the pump may contain solids. Do not face the working area or people with the exhaust port, so as to avoid personal injury.

10. When the diaphragm fails, the conveying material will be ejected from the exhaust muffler.

11. When transporting flammable and toxic fluids, please connect the vent to a safe place away from the work area.

12. Please connect the exhaust port and muffler with at least 3 / 8 "inner diameter smooth inner wall pipe.

13. The high pressure of fluid may cause serious personal injury and property loss. Please do not carry out any maintenance work on the pump and material pipe system when the pump is pressurized. If maintenance is required, cut off the air intake of the pump, open the bypass pressure relief mechanism to relieve the pressure of the pipeline system, and slowly loosen the connected pipe joints.

14. If the delivery of harmful and toxic fluid pump, please do not send the pump directly to the manufacturer for repair. Handle properly according to local laws and regulations, and use pure accessories of Shanghai wangquan Pump Co., Ltd. to ensure service life.

15. The pump with aluminum alloy material used in liquid conveying part should not be used to transport liquid containing Fe3 +, halogenated hydrocarbon and other halogenated hydrocarbon solvent, which will cause corrosion and cause pump body burst.

16. Ensure that all parts contacting the conveying body will not be damaged by the corrosion of the conveying fluid.

17. Ensure that all operators are familiar with the operation and use of the pump and master the precautions for safe use of the pump. If necessary, provide necessary protective equipment.

18. Use the pump correctly and do not allow long-term idling.
