Operating pneumatic diaphragm pump precautions:
1. Ensure that the maximum particles contained in the fluid do not exceed the maximum safe passing particle diameter standard of the diaphragm pump.
2, the intake pressure should not exceed the maximum allowable pressure of the diaphragm pump, higher than the rated pressure of compressed air may lead to personal injury and property loss and damage to the performance of the pump.
3, to ensure that the pump pressure of the pipeline switcher can withstand the highest output pressure, to ensure that the drive gas switch clean and normal working conditions.
4, electrostatic sparks may cause explosion resulting in personal injury and loss of property, according to the need for a large enough cross-sectional area of the wire, the diaphragm pump on the ground screw properly and reliably grounded.
5, pneumatic diaphragm pump grounding requirements in line with local laws and regulations and some special requirements of the site.
6. Tighten the pump and the connecting nozzle joints to prevent electrostatic sparks caused by vibration impact. For antistatic hoses.
7, to periodically check and test the reliability of the ground switch, the ground resistance is required to be less than 100 ohms.
8, maintain good exhaust and ventilation, away from flammable and explosive and heat sources.
9, the exhaust of the pump may contain solid objects, do not put the exhaust port against the working area or people, so as to avoid personal injury.
10, when the diaphragm fails, the conveying material will be expelled from the exhaust muffler.
11, when conveying 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 inner wall pipe to connect the exhaust port and muffler.
13, the high pressure of the fluid may lead to serious personal injury and property damage, please do not perform any maintenance work on the pump and the material pipe switcher when the pump is pressurized, if you want to do maintenance, first cut off the pump intake, open the bypass pressure relief mechanism to relieve the pipeline switcher, and slowly loosen the connected pipe joints.
14, the liquid transport part of the pump for aluminum alloy materials, please do not use to transport liquid containing Fe3+ and halogenated hydrocarbons and other halogenated hydrocarbon solvents, it will cause corrosion and cause the pump body to burst.
15, ensure that all parts in contact with the conveying body will not be corroded by the conveying fluid.
16, ensure that all operators are familiar with the operation and grasp the safety of the pump for precautions, if necessary, the necessary protective supplies.
17, correctly used in the pump, does not allow a long period of empty operation.
