NettetI have seen such “bare bones” reports before, one key motor shop in Connecticut that I worked with did this type report when there wasn’t any contractural obligation for something better. The reporting was done by a technician, perhaps after 1-hour into the test run, and something like the Metrix chart used as a criteria for acceptance. NettetIn vibration analysis reports, the readings are usually vibration, temperature, and working operation parameters. Readings will be shown in the report as trends. … NettetVibration Survey & Analysis Report Area: 332 “Cooling Water System” Equipment Description: Cooling Tower Fan ‘A’ Equipment ID: 332-00-CT001A Equipment design: … fomc member brainard

Nettet15. mai 2024 · To begin an evaluation, check in first on the basic measures of motor performance: current levels, power, voltage, and resistance. Preliminary tests are generally done using the ubiquitous multimeter, which can provide diagnostic information for all kinds of motors. Motor Test Methods: Isolating the Problem Nettetload. Since vibration levels are not constant, to measure vibra-tion, many times it is necessary to perform what is referred to as a modulation test. In a modulation vibration test the motor is al-lowed torun for a period of typically 10or 15 min,and vibration is recorded continuously to allow the maximum and minimum to be established. fomc minutes 2022 march fomc member waller

Detail observations: In looking at the motor data, air handler unit #1 shows some elevated vibration on the motor in the vertical and axial planes

NettetThere is vibration from motor unbalance, vibration from gearing and bearings. An accelerometer placed at any one point on the geared motor will measure a COMPLEX VIBRATION waveform as shown in the time drawing on the left side. This is the summation of all the vibration present at that location.
