9.15.5 Estimate trial weights
The Estimate Trial Weight option lets you enter physical data describing the rotor, along with
selected reference run data, to calculate the trial weight to reduce vibration due to
imbalance. The analyzer calculates the heavy and light spots.
Note
This is available only in Advanced Balance mode.
Note
The system lag and sensor lag affect the accuracy of the heavy spot. Rotor weight, radius, and
amplification factor affect the accuracy of the trial weight size. This calculation is only an estimate.
Your inputs and unaccountable cross-effects in multi-plane solutions affect the accuracy of the
estimates. Ensure you enter accurate data.
Procedure
1.
From the Balance main menu, press F4 Acquire Data.
2. Select a trial run.
3. Press ALT > F6 Calculator Mode > F6 Estimate Trial Weights.
4. Set the following options as necessary.
Option Description
F2 Select Meas.
Plane
Select the measurement plane to use. You may want to select the
measurement plane nearest the weight plane that has the readings you
want to use. The default is measurement plane 1.
F3 Select Weight
Plane
Select the weight plane to use. You may want to select the plane nearest
the measurement plane that has the readings you want to use. The default
is weight plane 1.
F4 Enter Rotor
Weight
Enter the weight of the rotor between 0.00 and 100,000 lbs or 0.00 and
45454.54 kg. The default is 1.
F5 Enter Tr Wght
Radius
Enter the radius between 0 and 650 inches where you placed the trial
weights on the rotor. The default is 1.
F6 Enter Sensor
Lag
Enter the sensor/phase lag in degrees introduced by the sensor. For
Emerson supplied accelerometers, sensor lag is normally 0 degrees. The
default is 0.
F9 Select MPT in
Plane
Enter the measurement points to use. You can average all readings in a
specific measurement plane. The default is the first point defined.
Note
If one measurement point has much higher magnitudes than the others,
averaging may give the best results.
F10 Select
Speed
Enter the measurement speed with the readings, if more than one speed
was defined. The default is speed 1.
