Pneumatic diaphragm pump conveying Dust
Dust conveying is a classic application of the pneumatic diaphragm pump, there is demand of the customer after pneumatic diaphragm pump, the choose and buy when using should notice what item?Fault occurs and how to deal with?The content of these will be will be introduced in this paper.
Pneumatic diaphragm pump for conveying powder has the advantage that powder material conveying in the closed management, can avoid the operator as far as possible to contact with the powder, especially for some poisonous and harmful powder, ensure the personal safety;To avoid the dust flying around in the production workshop, reduce air pollution and waste of raw materials (used special air release components).
Design of air induction system, fluidization gas can be separated and pump motor drive gas, avoid the material air contact oxidation and deliquescence, fluidization gas separately for further purification and drying (contact with powder), you can use other gas (e.g., nitrogen and other inert gases).
System economy, simple out-of-the-box - unlike expensive traditional large complex pre-installed powder conveying system, portable, easy moving use (can be installed on the trolley, the car can be customized).Put the box, free installation and debugging.

Dust the pneumatic diaphragm pump when need to pay attention to the following items:
1, keep good exhaust and ventilation, away from flammable and explosive and heat source.Grounding demands in accordance with local laws and regulations and the requirements of the scene of some of the special requirements.
2, ensure that all operating personnel familiar with the operation and master the safe use of pneumatic diaphragm pump considerations, if necessary, ration the necessary protective equipment.
3, ensure that the fluid contains particles does not exceed the maximum safe through the grain diameter of the pump.
4, inlet pressure does not exceed the maximum permissible use of the pump pressure, higher than the rated pressure of the compressed air can cause personal injury and property loss and damage to the performance of the pump.
5, to ensure that the pneumatic diaphragm pump pump pressure pipeline system can withstand the achieved highest output pressure, guarantee the normal work of the drive gas circuit system of cleaning and conditions.
6, an explosion caused by spark may cause personal casualty and property loss, according to the need to use large enough cross-sectional area of the conductor, the grounding screw properly reliable grounding on the pump.
7, good fastening pump and all control of joint prevent due to the vibration impact rub spark.Use antistatic hose.
Eight, to periodically check and test the reliability of the grounding system, grounding resistance less than 100 ohms.
9, pneumatic diaphragm pump exhaust may contain solid material, not to vent to the workspace or a person, so as not to cause personal injury.
10, when the diaphragm failure, conveying the material will be spewing from the exhaust muffler.

Dust the pneumatic diaphragm pump, diaphragm pump no actions or run slow, this is what reason is caused?We can start from the following points to check.
1. Check the pneumatic diaphragm pump in the air valve piston activity is normal.
2. Check that the pneumatic diaphragm pump air valve is stuck, clean with cleaning fluid air valve.
3. Check the pneumatic diaphragm pump air valve for wear and replace the new parts when necessary.
4. Check the air inlet side mesh or air filtration devices have impurities.
5. Check the centrosome sealing parts, if serious wear and tear, is unable to achieve sealing effect, and the air will be drained from the air outlet end.
6. Check the oil type.Add the lubricating oil if the above suggested oil viscosity, the piston may be stuck or doesn't work properly.It is recommended to use thin oil and antifreeze.
