Stainless steel filter mesh environment
Stainless steel filter mesh environment
1. Stainless steel filter mesh it is used for screening and filtration under acid and alkali environmental conditions. The petroleum industry is used as mud net, chemical chemical fiber industry, as sieve screen and electroplating industry as pickling net.
2 used in mining, petroleum, chemical, food, pharmaceutical, machinery manufacturing and other industries.
The service life of ordinary mesh belts is very short compared to stainless steel mesh belts, because our use environment is very complex, such as high temperature, corrosion and other environments. As we all know, stainless steel mesh belt is characterized by high temperature resistance, corrosion resistance and high strength.
First, use in the case of ultra high temperature exceeding 400 ° C
When the mesh belt is in normal operation, the temperature rises due to the heat of the conveyed material, and the strength of the transport forgetting belt gradually decreases as the temperature rises. The use limit of the stainless steel mesh belt will depend on the temperature generated by the rotational friction of the material and the mesh belt and the temperature of the material. If the temperature exceeds 400 °C, it will affect the service life of the stainless steel mesh belt. Please consult the stainless steel mesh belt manufacturer. Under normal circumstances, the stainless steel mesh belt is resistant to high temperature, so it will not affect its service life at 400 °C. However, due to different manufacturing processes, the service life of stainless steel mesh belts manufactured by various manufacturers is different.
The following issues must also be considered when using stainless steel mesh belts at high temperatures.
a) The heat generated by the mesh belt due to friction during operation.
b) The difference in thermal expansion coefficient of the stainless steel mesh belt due to the difference in manufacturing process, when different materials are welded together, there is a possibility of thermal fatigue.
c) The case where the expansion between the parts causes an intermittent decrease when the ambient temperature exceeds 400 ° C should also be fully considered.
e) Ordinary mesh belts work hot and brittle at high temperatures, as do stainless steel mesh belts.
f) brittleness of carbon precipitation;
g) the effect of temperature changes on the use of stainless steel mesh belts (cooling and expansion);
h) The influence of high temperature environment on lubrication, silicon, graphite and molybdenum disulfide lubricating oil have good heat resistance.
Second, when the mesh belt is exposed to corrosive materials, it will have adverse consequences. First, the mesh belt parts will become thinner and thinner, resulting in accelerated wear. The rust on the common mesh belt parts will also affect the flexible rotation of the stainless steel mesh belt hinges and rollers. When the stainless steel mesh belt is continuously operated in an acidic or alkaline environment, stress corrosion and crystal corrosion may occur in the parts.
When using a mesh belt in a corrosive environment, great attention must be paid to the choice of materials for the mesh belt parts. Whether the mesh belt with the martensitic stainless steel series as the part will produce rust depends on the specific working environment. Mastering anti-corrosion technology is very useful for proper use of mesh belts in corrosive environments.
Third, use the mesh belt in the grinding environment
The use of mesh belts in a grinding environment can cause particularly serious wear. In order to ensure the service life of the mesh belt, it must be noted when using it:
a) The mesh belt can be prevented from being directly exposed to abrasive materials by installing a chain cover;
b) When the mesh belt is exposed to the abrasive material, it is necessary to select the appropriate conveyor type;
c) reduce the chain speed as much as possible;
d) In order to reduce the pressure of the hinge formed by the pin and sleeve of the mesh belt, please select a larger mesh belt;
e) Please use grease lubricant.
