Generally, many important equipment in cement plant are driven by triangular belt. Due to the continuity of the production process of the new dry process cement production line, higher requirements are put forward for the continuous and stable operation of mechanical equipment, especially in the sintering stage of clinker. The operation state of these equipment is directly related to the operation rate of kiln and clinker output, so it is very important to master the state of triangular belt on these equipment.
If the V-belt is too loose or slippery during operation, it will wear too fast, heat and even burn out, resulting in shortened service life. However, since these equipment are related to the operation of the kiln, these equipment in operation cannot be stopped for inspection. If the problems existing in the triangular belt can be found in time and the countermeasures and preparations can be made in advance, the unnecessary kiln shutdown caused by the triangular belt can be reduced.
In order to solve this problem, after long-term observation and summary, the manufacturer of the triangular belt has found a method to check the triangular belt in operation, which is judged by measuring the surface temperature of the triangular belt with an infrared thermometer. Under normal operation, the surface temperature of the V-belt is relatively stable, generally not more than 60 ℃, and there is no significant difference in the surface temperature of the V-belt of each equipment.
By measuring and recording these data, the temperature value of the triangular belt under normal conditions is mastered. However, if the triangular belt of a certain equipment is too loose, slippery or other abnormal phenomena, its surface temperature will be significantly higher than the normal temperature, which can reach 80 ℃ or even higher. If the situation is serious, it can even smell the smell of rubber. For example, the patrol inspection personnel once measured the temperature close to 100 ℃ in a daily temperature measurement inspection of the triangular belt, and the triangular belt began to break within a few minutes.
This shows that the higher the surface temperature of the triangular zone, the greater the possibility of fracture. When it is close to a certain limit value, fracture will occur. Due to the different materials and quality of different brands of triangular belts, the temperature they can withstand and the ultimate temperature resistance are also different. This requires the triangle belt manufacturers to measure and record this for a long time in the actual production and find out the law.
