Diaphragm pump is a new type of conveying machine and it is the most novel type of pump in China. Compressed air is used as the power source. For all kinds of corrosive liquids, liquids with particles, liquids with high viscosity, volatile, flammable, and highly toxic can all be pumped out. During use, you should pay attention to the following:
1. Ensure that the maximum particles contained in the fluid do not exceed the maximum safety of the pump through the particle diameter standard.
2. The inlet pressure should not exceed the pump's maximum allowable operating pressure. Compressed air above the rated pressure may result in personal injury and property damage and damage to the pump's performance.
3. The piping system that ensures the pump pressure can withstand the highest output pressure achieved and ensure the clean and normal working conditions of the driving air circuit system.
4. Electrostatic sparks may cause personal injury or death and property damage due to explosion. Use a wire with a sufficiently large cross-sectional area as required to properly and reliably ground the grounding screw on the pump.
6. Fasten the pump and each connecting pipe joint to prevent electrostatic sparking due to vibration and shock. Use anti-static hoses.
7, to maintain good exhaust and ventilation, away from flammable and heat sources.
8. When transporting flammable and toxic fluids, please take the outlet to a safe place away from the work area.
9, please use at least 3/8 "inner diameter inner wall smooth pipe connection exhaust and muffler.
10. If a hazardous toxic fluid pump is being transported, do not send the diaphragm pump directly to the manufacturer for repair. According to local laws and regulations properly handled, and use Wenzhou Zhongnai Pump Co., Ltd. genuine parts to ensure the service life.
11, the liquid transport part of the use of aluminum alloy pump, do not use to transport Fe3 +-containing liquids and halogenated hydrocarbons and other halogenated hydrocarbon solvents, corrosion will cause the pump body burst.
12. Ensure that all components that come in contact with the transport body are not corroded by the transported fluid.
13, the correct use of the pump, does not allow long time running.
In addition, when using a diaphragm pump, pay attention to the completeness of personnel. Ensure that all operators are familiar with handling and mastering the safe use of the pump. If necessary, provide necessary protective equipment.
The high pressure of the fluid may result in serious personal injury and property loss. Please do not perform any maintenance work on the pump and the feed pipe system when the pump is pressurized. If maintenance is required, cut off the air intake of the pump and open the bypass. The pressure relief mechanism relieves the pressure in the piping system and slowly loosens the connected piping joints.
The exhaust of the pump may contain solid objects. Do not expose the exhaust port to the work area or to avoid personal injury.
When the diaphragm fails, the conveyed material is ejected from the exhaust muffler. Therefore, to periodically check and test the reliability of the grounding system, it is required that the grounding resistance be less than 100 ohms.
When using a diaphragm pump is to pay attention to what matters:
