Routine Maintenance & Operation

Once the unit has been put into operation, a routine maintenance schedule should be set up to accomplish the following:

1.Lubrication of bearings and motor.

2.Bypass air dampers should be checked for freedom of operation and wear.

3.Wheel, housing, bolts and set screws on the entire fan should be checked for tightness.

4.Any dirt accumulation on the wheel or in the housing should be removed to prevent unbalance and possible damage.

5.Inspect fan impeller and housing looking for fatigue, corrosion, or wear.

CAUTION

When operating conditions of the fan are to be changed—speed, pressure, temperature, etc.— consult Greenheck to determine if the unit can operate safely at the new conditions.

Fan Operation

All fans should be run every thirty (30) days, or at least “bumped” every thirty days. It is preferred that each fan is run as this causes all electrical and mechanical components to get up to temperature, displacing any formed condensation, redistributes load on bearings, and redistributes grease in the bearings (motor and shaft bearings).

V-Belt Drives

V-belt drives must be checked on a regular basis for wear, tension, alignment and dirt accumulation. Premature or frequent belt failures can be caused by improper belt tension (either too loose or too tight) or misaligned sheaves. Abnormally high belt tension or drive misalignment will cause excessive bearing loads and may result in failure of the fan and/or motor bearings. Conversely, loose belts will cause squealing on start-up, excessive belt flutter, slippage and overheated sheaves. Either excessively loose or tight belts may cause fan vibration.

When replacing V-belts on multiple groove drives all belts should be changed to provide uniform drive loading. Use a set of matched belts whenever possible. Do not pry belts on or off the sheave. Loosen belt tension until belts can be removed by simply lifting the belts off the sheaves. After replacing belts, ensure that slack in each belt is on the same side of the drive. Belt dressing should never be used.

Do not install new belts on worn sheaves. If the sheaves have grooves worn in them, they must be replaced before new belts are installed.

The proper tension for operating a V-belt drive is the lowest tension at which the belts will not slip at peak load conditions. Belts are adjusted by raising or lowering the motor pivot plate. For initial tensioning, the proper belt deflection halfway between sheave centers is 1/64 inch for each inch of belt span.

For example, if the belt span is 64 inches, the belt deflection should be 1 inch using moderate thumb pressure at mid-point of the drive. Check belt tension two times during the first 24 hours of operation and periodically thereafter.

Deflection = Belt Span 64
