The application of wear-resistant ceramics on the damper
pneumatic conveying systems in industrial enterprises are largely controlled by the damper. The damper changes the direction of the wind in the process of opening/closing. At the same time, under the condition of constant pressure, it accelerates the flow rate of materials, which is easy to cause erosion to the damper tube wall. Generally, if the damper is washed out of the groove, powder leakage will occur, and the damper needs to be replaced. Start cleaning immediately
in order to solve this problem, we need to find a very wear-resistant material to replace the cylinder wall of the damper or carry out anti-wear treatment year-on-year. Wear resistant ceramic materials with very high hardness can be said to be the best wear-resistant materials. I hope you who operate the experimental machine can do a good job in these seven points, but the toughness is not as good as steel, so you can only use the anti-wear treatment of the steel cylinder wall
wear resistant ceramics have the advantages of high hardness, wear resistance and so on. It is a very good way to deal with the problems such as aging degradation and discoloration and strength reduction of the damper with wear-resistant ceramics. However, the key to the surface protection treatment with wear-resistant ceramic patches is to pay attention to the following two points:
1. The installation of wear-resistant ceramics should be smooth and flat, and the height difference of ceramic parts should not be greater than 0.3mm, otherwise the damper will not be closed tightly, Powder leakage occurs
2. The ceramic installation should be firm and will not cause the ceramic to fall off during the operation of the damper
this puts forward high requirements for the process of viscose and operators. Our company adopts gwj-350 high temperature resistant inorganic adhesive developed in cooperation with Tsinghua University, which has excellent temperature resistance and adhesion. All indicators are far ahead in the domestic industry. After more than 10 years of market inspection, it is proved to be the most ideal ceramic and steel bonding material
our workers have more than 10 years of experience in ceramic mounting construction. After continuous training and summary, 4. Document summary and recent technical exchanges with Japanese counterparts, the mounting level has reached the highest level in China. In order to ensure the smoothness of ceramics after installation, first of all, ensure that the individual difference of ceramics is very small, and at the same time, be particularly careful in operation. Finally, make individual adjustments during general assembly to ensure that the inner wall is smooth and flat. (end)
