Dust delivery is a classic application of pneumatic diaphragm pump. Customers who need it should pay attention to what they should pay attention to after using the pneumatic diaphragm pump. What should be done in case of failure? These are the contents to be introduced in this article. Pneumatic diaphragm pump in the process of conveying dust Analysis of pneumatic diaphragm pump for conveying dust has the advantage that the powder material in the closed management of delivery, to avoid the operator to minimize contact with the powder, especially for some toxic Harmful powder, to ensure personal safety; to avoid dust flying around in the production workshop to reduce air pollution and waste of raw materials (supporting the use of dedicated air release components). The design of a flow guidance system allows the separation of motor-driven gases from the fluidizing gas and the pump to prevent the material from contacting with air and deliquescence. The fluidizing gas can be further purified and dried separately (in contact with the powder), and other gases, such as nitrogen Inert gas). Economical, simple and ready to use; unlike the expensive, large, complex, pre-installed powder delivery system that is lightweight and easy to move anywhere (can be mounted on a cart that can be customized). That is to use, free installation and commissioning. Pneumatic diaphragm pump delivery of dust should pay attention to the following matters: 1, to maintain good exhaust and ventilation, away from flammable and heat sources. Grounding requirements in line with local laws and regulations and the requirements of the scene some of the special requirements of the provisions. 2, to ensure that all operators are familiar with the operation and use of pneumatic diaphragm pump safety precautions, if necessary, rationing necessary protective equipment. 3, to ensure that the maximum particles contained in the fluid does not exceed the maximum safety of the pump through the particle diameter standard. 4, the intake pressure does not exceed the maximum allowable pressure pump, compressed air above the rated pressure may result in personal injury and property damage and damage to the performance of the pump. 5, to ensure that the pneumatic diaphragm pump pressure piping system can withstand the highest output pressure, to ensure that the drive air system clean and normal working conditions. 6. Electrostatic sparks may cause explosion and lead to personal injury and property damage. If necessary, use a wire of sufficient cross-sectional area to properly ground the grounding screw on the pump. 7, fasten the pump and the connection pipe joints to prevent electrostatic sparks due to vibration impact. Use antistatic hose. 8, to periodically check and test the reliability of the grounding system, grounding resistance requirements of less than 100 ohms. 9, pneumatic diaphragm pump may contain solids in the exhaust, do not face the work area or exhaust port, so as to avoid personal injury. 10, when the diaphragm failure, the delivery of materials from the exhaust muffler squirting. Pneumatic diaphragm pump delivery of dust, the diaphragm pump does not move or slow operation, which is what causes? We can proceed from the following check. 1. Check the pneumatic diaphragm pump air valve piston activity is normal. 2. Check pneumatic diaphragm pump air valve is stuck, clean the air valve with a cleaning fluid. 3. Check pneumatic diaphragm pump air valve is worn, if necessary, replace the new parts. 4. Inspect the filter or air filter at the air inlet for impurities. 5. Check the center of the seal parts condition, if severe wear and tear, can not achieve the sealing effect, and the air will be discharged from the air outlet. 6. Check the type of lubricant. If the added lubricant is above the recommended viscosity, the piston may get stuck or malfunction. Recommend the use of thin and antifreeze lubricants.

PP plastic, polypropylene, commonly known as "baijiao",Scientific name: polypropylene.
Description:
PP Plastic is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP Plastic don't have the problem of environmental stress cracking.Polypropylene (PP Plastic) is a semi-crystalline thermoplastic.PP Plastichas high impact resistance, strong mechanical properties, resistance to many organic solvents and acid and alkali corrosion.
PP Plastic is widely used in industry and is one of the most common polymer materials.
Australian COINS are also made of polypropylene.
Polypropylene bonding:
K-720 is suitable for polypropylene PP plastic adhesion, suitable for large area plate lamination, high transparency, suitable for PP adhesion PP, PP adhesive PC, PP adhesive ABS,PP adhesive PVC, PP adhesive acrylic, PP sticky metal, PP stick wood.
K-7007 adhesion performance is roughly the same as k-720, light yellow and more economical.
K-620 is adhesive small area polypropylene PP glue, must be used with the k-650 treatment agent, the instant positioning, the strength is high.
Advantages:
1. Low density;
2. Heat resistance ;
3. Non deformation;
4. High stiffness;
5. High surface strength;
6. Good chemical stability;
7. Nontoxic and safe.
Disadvantage:
The main disadvantage of the fault polypropylene is that the high temperature rigidity is not enough, and the low temperature is brittle.
Poor environmental tolerance, outdoor use, easy to turn yellow and brittle.
Tensile strength of anisotropy, the products are easy to deform, continuous use of low temperature, high creep performance, and long - term load.
Poor printing performance.
Application:
1,Valve part, drinking water and sewage water pipe,
2,Sealing element, spraying carrier,
3,Corrosion-resistant trough and barrel, industrial applications that have acid and alkali-resistant requirement; wastewater and gas discharge equipment for industrial purpose,
4,Scrubbing tower, clean room, semiconductor plant and other related industrial equipment and machinery, food machinery and chopping board,
5,Electroplating process, toy part
Combustion characteristics: PP Plastic easy to burn, polypropylene from continue to burn after the fire, with the top of the flame is yellow, the bottom made in blue, with a small amount of smoke generated, burning melt dripping, and oil.
Specification: the thickness of PP sheet material can be produced from 0.3mm to 2mm, and the PP sheet material is of rolling material and width of 500-1000mm.
The thickness of the plate can be produced from 2mm to 200mm. The specification is 600*1200mm 1000*1000mm 1000* 2000mm. Other specifications can be customized as needed,and The diameter of the PP rod can be produced from 2mm to 250mm, the length is 1 meter, PP rod can be ordered to be more than 3 meters in length.
Color: white and black, other colors can be customized
Modified varieties: PP sheet have various enhancers and other auxiliaries can be added to make modified varieties, depending on the requirements
Storage methods:
Keep in tight, cool and dry place to ensure good ventilation
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
