Fans installed on upper floors or roof should use vibration isolators Spring isolators rubber-in-shear isolators inertia base Ductwork connected to fan should be independently supported.Sample of Spring Isolator: Sample of Spring IsolatorFan Start-up: Fan Start-up Tighten mounting hardware Verify Wheel-Cone clearance (B.I. Fans) Check sheave alignment and diameter ratio Check belt tension Check bearing lubrication Tighten set screws Close clean-out doors Verify proper placement of safety guards Verify proper wheel rotationSafety: SafetySafety First!: CLEAN OUT DOOR Safety First!PowerPoint Presentation: INLET SCREENPowerPoint Presentation: What does this switch do? Un-Safe MaintenanceBelt Drive Alignment: Belt Drive AlignmentPowerPoint Presentation: BELT TENSION PULLEY ALLIGNMENTPowerPoint Presentation: Impeller Clearance Inlet cone See sample nyb Installation and Maintenance handoutSetscrew Torque: Setscrew Torque See sample nyb Installation and Maintenance handoutFan Start-up: Fan Start-up The following items should be checked after 8 hours, after 24 hours, and after two weeks: Set screws holding wheel on shaft (or bushing bolts) Fan mounting hardware Belt/coupling alignment Belt tension (new belts may stretch a little) Bearing temperature (should be < 200°F ) Vibration and noiseBearing Temperature: Bearing Temperature Maximum bearing temperature 225°F or 106°C Normal operating range 125°F - 180°F or 51°C - 81°C Bearing temperature will increase during initial start-up and during Re-lubrication.MEASURING BEARING TEMPERATURE: MEASURING BEARING TEMPERATUREPowerPoint Presentation: Installation and Maintenance BearingsBearings: Bearings Proper Lubrication! A variety of bearing types can be used for fan bearings Ball RollerRecommended Lubrication: Recommended Lubrication Texaco Premium RB Mobile Mobilith 22 Standard Oil Amolith #2 Gulf Oil Gulf Crown #2 Shell Alvania #2 Comparable Premium Quality NLGI #2 Grade Multi-Purpose GreaseCauses of Bearing Failures: Causes of Bearing Failures Improper Installation Setscrew torque Assembly Misalignment Poor Lubrication Not enough Moisture Contamination Miscellaneous Bearing defect Loading Shipping damage UndeterminedMisalignment: Misalignment Bearings Shafting Top ViewMaintenance During Storage: Maintenance During Storage Store in humidity and temperature controlled area Protect fan bearings from harsh environment rain, snow, chemicals Rotate shaft at least every two weeks Re-lubricate with new grease every monthInstallation and Maintenance: Installation and Maintenance TroubleshootingCommon Causes of Fan Vibration: Common Causes of Fan Vibration Aerodynamic Unstable fan performance System effect Mechanical Material build-up on wheel Wheel deterioration or corrosion Belt alignment Bearings Support structure Motor, sheave, or fan balance Change operation point or fan size Change inlet/outlet connection(s) Clean wheel periodically Inspect wheel, replace when needed Regular maintenance checks Regular maintenance Add reinforcements for stiffer frame Rebalance after changes You do not have the permission to view this presentation.
