How Can We Ensure Optimal Performance of Underground Mining Axial Flow Fans?

To maintain the efficiency and safety of underground mining axial flow fans, regular monitoring and recording during operation are crucial. Operators should inspect and document key parameters every two hours, including motor current, voltage, power, stator temperature, axle temperatures, fan negative pressure, airflow, and vibration velocity. Any abnormal changes in these parameters must be reported and addressed promptly to prevent potential issues.

Additionally, it’s essential to follow strict guidelines for greasing motor bearings, adhering to the manufacturer’s specifications regarding greasing frequency, quantity, and grease type. Mixing different grease brands is prohibited, as it can lead to equipment failure. Timely cleaning of waste grease using appropriate discharge equipment also plays a vital role in maintaining the fan’s operational integrity.
