Application of wear-resistant ceramics in damper

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 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, it is necessary to find a very wear-resistant material to replace the cylinder wall of the damper or to carry out anti-wear treatment. The materials with very high hardness of wear-resistant ceramics can be said to be the best wear-resistant materials, but their toughness is not as good as that of iron and steel. Therefore, the method of anti-wear treatment on the steel cylinder wall can only be adopted

wear resistant ceramics have the advantages of high hardness and wear resistance. It is a very good method to use wear-resistant ceramics to deal with problems such as aging and degradation of the damper, resulting in discoloration and strength drop. However, the following two points should be paid attention to when using wear-resistant ceramic patches for surface protection:

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

2. The ceramic mounting shall be firm, and the ceramic will not 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 same industry in China. After more than 10 years of market inspection, it is proved that it is the most ideal ceramic and steel bonding material

our workers have more than 10 years of ceramic installation construction experience. After continuous training and summary, 4. document summary and recent technical exchanges with Japanese counterparts, the installation level has reached the highest level in China. In order to ensure the smoothness of the ceramic after installation, it is necessary to first ensure that the individual difference of the ceramic is very small, and at the same time, special care should be taken during the operation. Finally, individual adjustments should be made during the general assembly to ensure that the inner wall is smooth and flat. (end)
