Troubleshooting is the effort to identify and resolve differences between what was expected and what actually happened. The following four categories narrow the focus of attention and speeds up the evaluation process. Aerodynamic Performance – This applies to any of the five rating parameters of flow, pressure, speed, power and density and how they compare …
Noise is generally considered low quality, unwanted sound. The primary selection criterion for a fan is based not on its acoustical characteristics but on its ability to move the required amount of air against the required pressure. In addition, the fan must do so at a reasonable initial cost (it also may be required to …
FAN MANTENANCE To obtain maximum service life of your fans, it is recommended the following maintenance be implemented and recorded in a plant log book Ensure air intake space is unobstructed to avoid overheating the motors. On a weekly basis use an air hose to ensure all airways are clear and free of dust if …
Basic Principle Like most other rotating machinery, fans experience wear and require periodic maintenance and repairs. Dynamic surfaces in bearings and belt drives degrade over time. Fan blade surfaces may erode from abrasive particles in the airstream, and motors eventually require replacement or rewinding. Although some degree of wear is unavoidable, operating the system at …
Maintenance Items Common maintenance tasks on fan systems include: Periodic inspection of all system components Bearing lubrication and replacement Belt tightening and replacement Motor repair or replacement Fan cleaning The most costly consequence of improper maintenance is unscheduled downtime. Causes of this downtime vary according to the demands of the application. Because each system places …
