DRAFT Analyze and Advanced Analyze 6.7.2 Lines of resolution The resolution of the spectrum increases with the number of spectral lines. The more spectral lines, the more information the spectrum contains. Increasing the number of lines also increases the required memory and time to measure the spectrum. The spectrum consists of discrete spectral lines that display at fixed frequency intervals. The height of each spectral line represents the vibration amplitude at a frequency.
DRAFT Analyze and Advanced Analyze Option Description Force/Exponential The Force/Exponential window is the default for Impact mode. Impact testing normally requires two window types. The analyzer applies a Force window to the hammer channel, and an Exponential window to the response channel. The Force/Exponential window automatically applies these window types to the appropriate data. Configure the following parameters.
DRAFT Analyze and Advanced Analyze Option Description Peak Hold Average Display the largest amplitude of each spectral line. Use this option during a machine coast down or to monitor random fluctuations such as steam whirl or oil whirl. Synchronous Time Remove the vibration of other machines from the signal, so only the vibration from the reference machine remains.
DRAFT Analyze and Advanced Analyze PeakVue technology lets you find bearing or gear defects earlier than other measurements. PeakVue technology removes normal vibration signals and captures the actual amplitude of high-frequency impacts from bearing or gear defects. Bearing defect frequencies appear in the PeakVue spectrum at their fundamental frequencies and harmonics. The peaks are non-synchronous. Gear defects appear as peaks at the gear’s shaft turning speed frequency and harmonics.

DRAFT Analyze and Advanced Analyze Single-channel tests usually require additional tests to confirm, but the results of the bump test should show a peak at the resonant frequency. The impacts from the hammer place a small amount of force into the system at all frequencies. A resonance naturally amplifies the vibration at the resonant frequency. The peaks in the spectral data represent the resonant frequency (or frequencies).
DRAFT Analyze and Advanced Analyze 6.8.11 Bump Test Equipment Running The Bump Test Equipment Running confirms resonance when you cannot turn the equipment off to perform a normal bump test. It also helps remove background vibration. Use a normal hammer for this measurement. To perform the test in a frequency range, use a cursor to mark a frequency.

DRAFT Balance If you define two measurement points, 90 degrees apart, for each measurement plane, you can see if both axes react similarly. Occasionally, equipment does not react symmetrically due to a significant difference in constraint between axes or resonance. Note You can define up to three sensors for each measurement plane. No more than one sensor can be axial (to measure vibration parallel to the shaft), but you can define all three as radial to measure vibration perpendicular to the shaft.
Balance DRAFT Option Description F3 Select Display Units Select the type of units, including Accel (g's), Velocity (in/sec or mm/sec), or Displacement (mils or microns). The analyzer uses the units for computation and data display. The default is Displacement. F4 Data Units Select RMS, Peak, or Pk-Pk for sensor unit displays. The analyzer uses the units for computation and data display. The default is Pk-Pk. 4. 9.4.
DRAFT Balance Option Description 9.4.6 Off The analyzer does not use the CSI 2140 Four-Channel Input Adapter or external multiplexer. The analyzer acquires all data through the same channel, and you must manually start and accept each measurement. On The CSI 2140 Four-Channel Input Adapter controls software that switches between channels. The analyzer acquires all data on channels A to D, and you must specify the input channel for each measurement point.
Balance 9.4.7 DRAFT Enable or disable the runout measurement Runout is an optional measurement acquired using a displacement sensor during a slow roll of the rotor. A slow roll means the rotor rotates so slowly that readings from the sensors only detect mechanical irregularities on the rotor surface, not vibration. Use runout data to help normalize the balance data. Note This is available only in Advanced Balance mode. Procedure 1. From the Balance main menu, press F3 Job Setup. 2.
9.5.1 DRAFT Balance Measurement points A measurement point is the where you collect a measurement on the equipment. You must define at least one measurement point. The default setup distributes the points equally among the defined measurement planes. For example, if you set up seven points and three planes, plane 1 has three points, plane 2 has two points, and plane 3 has two points. The maximum number of points depends on the number of planes you set up.
Balance 9.5.2 DRAFT Add a measurement point to a measurement plane You can add up to three measurement points for a measurement plane. The points are added at the end of the list. Note This is available only in Advanced Balance mode. Procedure 1. From the Balance main menu, press F3 Job Setup. 2. Press Enter or F4 Meas. Plane Setup.

Balance DRAFT Key concepts for balancing machines • Imbalance causes vibration to occur at the rotational frequency (1xRPM) of the imbalanced rotor. • The vibration is directly proportional to the amount of imbalance. Doubling the amount of the imbalance doubles the amount or magnitude of the vibration. • A shift in the heavy spot results in an equal shift in the phase angle. • All weights in a single plane sum vectorially to equal a single heavy spot.
DRAFT Balance make the balancing job more difficult due to decreased linearity of the system response. Additional trim runs may be required and, once balanced, this machine may be difficult to keep balanced. As a general rule of thumb, address the worst problems first. Clean the rotor Cleaning the rotor is especially important if it often accumulates foreign material. Removing the material often corrects imbalance.
Balance DRAFT Store every balance job for later reference Use AMS Machinery Manager Data Transfer to transfer the job from the analyzer to the database. Save jobs to reduce setup time when you need to balance the equipment again. The necessary setup and dynamic data for one-run balancing are already available, which reduces the time you spend balancing the equipment. 9.16.
9.16.4 DRAFT Balance Identify the correction planes You can balance a rotor system exactly in N+2 planes (where N = the number of shaft criticals below operating speed). Most mechanical systems are designed to operate below their first shaft critical, so use 0 + 2 = 2 planes. Virtually all systems operate below their fourth critical, so use 3 + 2 = 5 planes. Sometimes a single shaft has only two balance planes, which normally allows an acceptable balance compromise, even if not exact.
Balance DRAFT Issue Potential solution The measured amplification factor is greater than six. The cause may be a rotational frequency close to a resonance that is amplifying the vibration. Check the resonant frequencies. Slight changes in weight size and location cause dramatic changes in the apparent degree of imbalance. Correction weights do not The expected improvement based on the current influence reduce vibration at all coefficients is marginal.
DRAFT 9.17.1 Part number Description 8BA1 Balancing Compass 8BA25 Balance Scale and Weights 404B Phototach (infrared) Balance Balancing Compass The Balancing Compass measures angular locations and relationships, which are essential tasks when balancing rotating equipment. The Balancing Compass can help ensure more accurate measurements and reduce the risk of error. You can measure and mark angles some distance from each other.
Balance DRAFT 2. Place the Balancing Compass on an axial face with the indicator needle pointing at 0 degrees. Figure 9-9: Attach and zero 3. Turn the rotor until the indicator reads the desired angular position from the applicable scale. This position is now aligned with the stationary reference. Figure 9-10: Turn the rotor Determine the position of a sensor or tachometer pick up from top dead center (TDC) 1.
DRAFT Balance 2. Attach the Balancing Compass to any axial face of the rotor so you can see it throughout one rotation. This includes the end of the shaft, the axial face of the rotor itself, or the axial face of anything attached to the shaft, such as a sheave or coupling. 3. Without rotating the rotor, turn the Balancing Compass so the indicator needle points to 0 degrees. Figure 9-12: Attach and zero 4. Turn the rotor until the reference mark is at TDC.
Balance DRAFT Double scale 0-360° clockwise 0-360° counter clockwise Magnetic backing Requires vertical orientation on axial face of the shaft or rotor 9.17.2 Clamp-on reusable trial weights The CSI Model 8BA20 Trial Weights Assortment includes nine reusable clamp-on trial weights. Weights are clamped on by using knurled cup point set screws in combination with cone point set screws on the opposing side.
DRAFT Balance Note As a practical matter of safety, Emerson recommends using trial weights that are securely bolted or welded to the rotor being balanced. Emerson does not warrant the applicability or safety of using any weight glued or clamped onto a rotor, including those contained in this kit. CAUTION! Use these weights at your own risk. Exercise extreme caution when using weights such as these. Never allow anyone to stand in the potential line-of-fire of a thrown weight.
Balance DRAFT As would be expected, both the 2nd and 3rd configurations proved to hold considerably better than having set screws on only one side. The 3rd configuration usually resulted in some performance improvement over the 2nd configuration however, it gave less consistent results (probably due to the difficulty in getting all the set screws torqued uniformly).
