Fan Vibration Levels

Each unit as shipped is trim balanced to operate smoothly. To

provide satisfactory operation after shipping and installation,

use the accepted industry guidelines for field balancing fans.

.

Table 22: Vibration Levels

Fan speed (rpm)

Vibration

800 or less

5 mils maximum displacement

801 or greater

0.20 in/sec. maximum velocity

Note: Excessive vibration from any cause contributes to premature fan and motor bearing

failure. Monitor overall vibration levels every six months of operation. An increase in levels

is an indication of potential trouble.

Vibration Causes

1. Wheel imbalance

a. Dirt or debris on wheel blades
b. Loose set screws in wheel hub or bearing-to-shaft

c. Wheel distorted from overspeed

2. Bent shaft
3. Drive faulty

a.

Variable pitch sheaves—Axial and radial runout of

flanges; uneven groove spacing; out of balance.

Also similar faults in driven sheave.

b. Bad V-belts; lumpy, or mismatched; belt tension

too tight or too loose.

4.  Bad bearings, loose bearing hold-down bolts
5.  Motor imbalance
6.  Fan section not supported evenly on foundation
