In the cement production process, the operating efficiency of the high temperature fan not only affects the normal production process of cement, but also has a significant impact on the unit power consumption of the product.
The operating reliability and stability of the high-temperature fan are significantly improved. The dynamic balance of the fan rotor after the transformation is higher. The coupling adopts a flexible coupling that has a better damping effect on shock and vibration. The inlet ring and the guide cone are used Reasonable clearance design to reduce the turbulence of the airflow to the impeller, and the impeller lining material adopts imported high-hardness composite wear-resistant liner, these designs ensure the high reliability and stability of the equipment.
After the high temperature fan is reformed, the vibration of the bearing seat is reduced and the operation is more stable. This will reduce the wear of bearings and other components, thereby reducing equipment failure rates and saving maintenance costs. At the same time, due to the high reliability and stability design of the fan, the use of circulating cooling water to cool down the lubricating oil of the fan bearing is eliminated, saving related costs.
From the perspective of process, the reduction of the current of the high-temperature fan increases the adjustment range of the air volume and pressure required by the preheater and the rotary kiln, which greatly increases the flexibility of operation and better meets the needs of calcination. Considering the utilization of spare parts, the fan rotor replaced during the transformation can be used as a spare part for other fans of the same model of the same production line. When the same type of rotor is repaired and replaced, the rotor that is used as a spare part can be put into use immediately, which not only saves maintenance time The cost of spare parts can also be reduced, and the maintenance cycle can be reduced, so that production can be restored as soon as possible.
