What Should Be Considered for Maintenance of Explosion-proof Underground Long-distance Axial Flow Fans?

When dealing with explosion-proof underground long-distance axial flow fans, proper maintenance during prolonged shutdowns is crucial. First, apply anti-rust measures to parts that are prone to corrosion. It’s essential to ensure that the motor and other electrical components remain rust-free as well. Regularly rotating the impeller by 180° can prevent static deformation and bending of the shaft.

Even during extended periods of inactivity, regular maintenance is necessary to keep the equipment in optimal condition. After a long shutdown, always conduct a test run before resuming normal operations to ensure everything is functioning correctly. By following these precautions, the reliability and efficiency of the fans can be maintained over time.
