The pneumatic diaphragm pump is a volume pump with the compressed air as the power, the reciprocating deformation of the diaphragm and the volume change. Its working principle is similar to the plunger pump.
The following points should be paid attention to when the pneumatic diaphragm pump is operated.
1. Ensure that the largest particle contained in the fluid is not more than the maximum safety of the diaphragm pump through the standard of particle diameter.
2, the inlet pressure should not exceed the maximum allowable service pressure of the pump. The compressed air above the rated pressure can cause personal injury and property damage and damage the performance of the pump.
3. The pipe system that ensures the pressure of the diaphragm pump can bear the highest output pressure to ensure the clean and normal working conditions of the drive gas system.
4, electrostatic spark may cause personal injury and property loss due to explosion. According to the need to use enough large area of wire, the ground screws of the diaphragm pump can be reliably and reliably grounded.
5 and Earthing requirements are in accordance with the requirements of the law of the local law and some special requirements of the site.
6. Fasten the diaphragm pump and the connecting pipe joint to prevent the electrostatic spark caused by the vibration impact. Use antistatic hose.
7. Periodic inspection and testing of the reliability of the grounding system requires that the grounding resistance is less than 100 ohms.
8, keep good exhaust and ventilation, away from flammable and explosive and heat source.
9, the pump may contain solids in the exhaust. Do not pose the exhaust port to the work area or the person, so as to avoid the injury of the body.
10. When the diaphragm fails, the conveyed material will be ejected from the exhaust muffler.
11. When transporting flammable and toxic fluid, please connect the drain to a safe place away from the working area.
12. Please use at least 3/8 "the pipe with a smooth inner wall to connect the vent and muffler.
13, the fluid pressure can cause serious casualties and property losses, do not pump pressure when any maintenance work of the pump and tube system, such as the need to do maintenance, the first cut off the pump inlet, pressure piping system pressure relief relief mechanism to open the bypass, the pipe joints slowly release the connection.
14, such as the transport of toxic and toxic fluid pump, please do not send the pump directly to the manufacturer to repair. Properly handled according to local laws and regulations, and use the pure accessories of Shanghai Guang Zheng pump valve company to ensure the service life.
15, liquid transport part of the pump using aluminum alloy material, please do not transport liquid containing Fe3+ and halogenated hydrocarbons and other halogenated hydrocarbon solvents, it will cause corrosion and cause pump burst.
16, ensure that all the parts of the contact conveyer will not be corrupted by the corrosion of the fluid transported.
17, ensure that all operators are familiar with the operation and control of the safe use of the pump, if necessary, the necessary protective supplies.
18, the correct diaphragm pump, not allowed for a long time air transfer.
