Maintenance of shredder fan and analysis of vibration causes

What is the maintenance process of the pulverizer fan? The following small series will give you a detailed introduction. The maintenance of shredder fan needs to follow the following aspects.

Fan maintenance must first emphasize power failure and shutdown. The fan must be used and maintained by special personnel. Except that the lubricating oil shall be replaced after each disassembly and maintenance, the lubricating oil shall be replaced every 3-6 months under normal conditions. The fan shall not operate under fault conditions. Regularly remove the dust inside the fan, especially the dust, dirt and other impurities on the impeller to prevent corrosion and imbalance.

Regularly check the sensitivity of thermometer and oil pointer. The vibration of pulverizer fan is usually caused by bearing wear or damage. The foundation or base is not rigid or firm enough; The rotating shaft moves too much or the coupling connection is loose; The fan flow is too small or the suction inlet flow is uneven; The efficiency of the dust collector is low, resulting in wear or ash accumulation of the fan impeller and imbalance.

The above is the analysis and introduction of the maintenance and vibration causes of the shredder fan.
