Operation and use of the hottest pneumatic diaphra

The operation of pneumatic diaphragm pump uses

pneumatic diaphragm pump is a positive displacement pump driven by compressed air and causing volume change through reciprocating deformation of diaphragm. Its working principle is similar to that of plunger pump. When using the pneumatic diaphragm pump to operate, pay attention to the following points:

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 pressure of the pump. Compressed air above the rated pressure may cause personal injury, property loss and damage to the performance of the pump

3. Ensure that the pipeline system with pump pressure can withstand the maximum output pressure, and ensure the cleanness and normal working conditions of the driving gas circuit system

4. Electrostatic sparks may cause explosion, resulting in personal injury and death accidents and property losses. Use wires with sufficient cross-sectional area as needed to properly and reliably ground the grounding screw on the pump

5. Grounding requirements comply with local laws and regulations and some special requirements on site

6. Fasten the pump and all connecting pipe joints to prevent the high-precision Italian ATOS C servo valve and high-precision pressure sensor from generating electrostatic sparks due to vibration, impact and friction. Use antistatic hose

7. Periodically check and test the reliability of the grounding system, and the grounding resistance is required to be less than 100 ohms

8. Keep good exhaust and ventilation, and keep away from inflammables, explosives and heat sources

9. The exhaust of the pump may contain solids. Do not bend the exhaust to the left for another 90 degrees, and the air port is facing the work area or people, so as to avoid personal injury

10. When the diaphragm fails, the conveyed materials will be ejected from the exhaust muffler

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

1 "Hu Qianlin said 2 Please use at least 3/8 "The pipe with smooth inner diameter and inner wall connects the exhaust port and muffler.

13. The high pressure of the fluid may cause serious personal injury and property damage. Please do not carry out any maintenance work on the pump and material pipe system when the pump is pressurized. If the rotor pump needs to be repaired, first cut off the air inlet 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, such as harmful and toxic transportation Please do not send the fluid pump directly to the manufacturer for repair. Properly handle according to local laws and regulations, and use genuine accessories of Shanghai wangquan Pump Co., Ltd. to ensure service life

15. Pumps made of aluminum alloy are used for liquid delivery. Please do not use them to deliver liquid containing fe3+ and halogenated hydrocarbon and other halogenated hydrocarbon solvents, which will cause corrosion and pump body burst

16. It is also necessary to ensure that all parts in contact with the conveying body will not be corroded and damaged by the conveyed fluid

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

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