Dust conveying is a classic application of pneumatic diaphragm pumps, there is a demand for customers to buy pneumatic diaphragm pumps after the use of what matters should be noted? Failure and how to deal with it? These will be the contents of this article will be introduced.
The advantage of pneumatic diaphragm pumps for conveying dust is that the powder material is conveyed in a closed management, which can avoid the operation of workers as little contact with the powder, especially for some toxic and harmful powders, to ensure personal safety; to avoid the situation of dust flying around in the production plant, reducing air pollution and waste of raw materials (supporting the use of special air release components).
Designed with an airflow induction system, the fluidised gas and the pump motor drive gas can be separated to avoid oxidation and dampness in contact with the material air, the fluidised gas can be further purified and dried separately (in contact with the powder), other gases (such as nitrogen and other inert gases) can be used.
Economical and simple ready-to-use system - unlike expensive traditional large and complex pre-installed powder conveying systems, it is lightweight and can be easily moved anywhere (can be mounted on a trolley, trolleys can be customised). Ready to use, no installation and commissioning.
1. Maintain good exhaust and ventilation, away from flammable and explosive and heat sources. Grounding requirements in line with local regulations and legal requirements and the provisions of some special requirements of the site.
2、Ensure that all operators are familiar with the operation and use of pneumatic diaphragm pumps and master the safety of the use of precautions, if necessary, with the necessary protective equipment.
3, to ensure that the largest particles contained in the fluid does not exceed the pump's maximum safety through the particle diameter standard.
4, the inlet pressure should not exceed the maximum allowable pressure of the pump, higher than the rated pressure of compressed air may lead to personal injury and property damage and damage to the pump performance.
5, to ensure that the piping system of pneumatic diaphragm pump pressure can withstand the highest output pressure achieved, to ensure that the drive air system clean and normal working conditions.
6, electrostatic sparks may cause an explosion resulting in personal injury or death and property damage, according to the need to use a large enough cross-sectional area of the wire, the pump on the grounding screw properly and reliably grounded.
7、Tighten the pump and the connecting pipe joints to prevent electrostatic sparks due to vibration, impact and friction. Use anti-static hoses.
8, to periodically check and test the reliability of the grounding system, requiring grounding resistance of less than 100 ohms.
9, pneumatic diaphragm pumps may contain solids in the exhaust, do not point the exhaust port to the work area or people, so as not to cause personal injury.
10, when the diaphragm fails, the material conveyed will be ejected from the exhaust muffler.
1. Check whether the piston activity in the air valve of the pneumatic diaphragm pump is normal.
2. Check whether the air valve of the pneumatic diaphragm pump is stuck, clean the air valve with a cleaning solution.
3. Check whether the air valve of the pneumatic diaphragm pump is worn, and replace the new parts if necessary.
4. Check the air inlet end of the screen or air filter device for impurities.
5. Check the condition of the sealing parts of the central body, if it is severely worn, the sealing effect cannot be achieved and the air will be discharged from the air outlet end.
6. Check the type of lubricant. If the oil added is of a higher viscosity than the recommended oil, the piston may seize or not function properly. It is recommended to use a lighter and anti-freeze lubricant.
