Pneumatic diaphragm pump common fault solution, pneumatic diaphragm pump precautions

Pneumatic diaphragm pump is a new type of conveying machinery, using compressed air as power source, for all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumped out, has been formed production, product quality is highly praised. According to the investigation found that the main characteristics of this pump is not need irrigation water, can pump the flow of liquid, but also can transport some is easy to flow medium, suction height, adjustable head (0-50 meters) air source pressure only greater than 1kg/cm2 can work, fire and explosion proof, With submersible pump, self priming pump, impurity pump, shield pump, mud pump all functions and many characteristics of conveying machinery.

Pneumatic diaphragm pump use precautions

Pneumatic diaphragm pump is compressed air as the power, through the diaphragm reciprocating deformation caused by volume changes of the positive displacement pump, its working principle is similar to the plunger pump. A lot of friends and customers called to ask about the correct use of pneumatic diaphragm pump, each response is almost the same, again and again, repetition is power, Xiaobian here sorted out, the following Longyang pump valve together to understand the use of pneumatic diaphragm pump precautions.

Pneumatic diaphragm pump use notes:

1, ensure that the particles contained in the fluid do not exceed the pump safe through the particle diameter standard. Pneumatic diaphragm pump exhaust may contain solid objects, do not exhaust port to the working area or people, so as to avoid personal injury. This is also very important, personal safety, the use of pneumatic diaphragm pump in the work must pay attention to this.

2, the intake pressure should not exceed the allowable use pressure of the pump, higher than the rated pressure of compressed air may lead to personal injury and property loss and damage the performance of the pump.

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

4. Electrostatic sparks may cause explosion and personal injury and property loss. According to the need to use a large enough cross-sectional area of the wire, the grounding screw on the pump properly and reliably grounded.

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

6. Tighten the pump and the connecting joints to prevent electrostatic sparks from vibration impact. Use an antistatic hose.

7, to periodically check and test the reliability of the grounding system, the grounding resistance is required to be less than 100 ohms. Regular maintenance inspection is a necessary condition for good operation of pneumatic diaphragm pump, we can not forget oh.

8, maintain good exhaust and ventilation, away from flammable and explosive and heat sources. This is very important. Stay away from dangerous things.

9, when conveying flammable and toxic fluids, please connect the outlet to a safe place away from the work area. It's safe.

10. Please connect the exhaust port to the muffler with at least 3/8 "smooth inner diameter pipe.

11, when the diaphragm failure, the conveying material will be expelled from the exhaust muffler.

12, the correct use of the pump, does not allow a long time of empty operation.

13, pneumatic diaphragm pump such as the delivery of harmful and toxic fluid pump, please do not send the pump directly to the manufacturer to repair. Properly handle according to local laws and regulations, and use pure accessories to ensure service life.

14, to ensure that the pump pressure pipeline system can withstand the output pressure, to ensure that the driving gas system clean and normal working conditions.

15, electrostatic sparks may cause explosion resulting in personal injury and loss of property, according to the need to use a large enough cross-sectional area of the wire, the pump on the ground screw properly and reliably grounded, the article here to give you is necessary to understand the characteristics of pneumatic double diaphragm pump.

16, pneumatic diaphragm pump to ensure that all contact with the parts of the conveying body will not be transported fluid corrosion damage.

17. Tighten the pump and the connecting joints to prevent electrostatic sparks from vibration impact. Use an antistatic hose.

18, pneumatic diaphragm pump fluid high pressure may lead to serious personal injury and property damage, please do not in the pump pressure, pump and material pipe system for any maintenance work, such as to do maintenance, first cut off the pump intake, open the bypass pressure relief mechanism to relieve the pipeline system, slowly loosen the connection of the pipe joint.

19, liquid transport part of the use of aluminum alloy material pump, please do not use to transport containing Fe3+ liquid and halogenated hydrocarbons and other halogenated hydrocarbon solvents, it will cause corrosion caused by the pump body burst.

20. Ensure that all the operators are familiar with the operation and use of the pump safety precautions, if necessary, the necessary protective supplies.

21, pneumatic diaphragm pump grounding requirements in line with local laws and regulations and some special requirements of the site.

22, the intake pressure should not exceed the allowable use pressure of the pump, higher than the rated pressure of compressed air may lead to personal injury and property loss and damage the performance of the pump.

23, pneumatic diaphragm pump to ensure that the particles contained in the fluid do not exceed the pump safe through the particle diameter standard.

The above is the use of pneumatic diaphragm pump precautions, pneumatic diaphragm pump application market pneumatic diaphragm pump structure is simple, convenient installation and maintenance, pump transmission medium will not contact the valve, rod and other moving parts, unlike other types of pump due to the wear and tear of rotor, piston, gear, blade and other parts and the performance is gradually reduced.
