“…However, if one adopts less restrictive requirements for the vibration intensity levele.g., the acceptable vibration velocity v RMS (8.0) = 8.0 mm/s (as extensively presented in the paper [18])-then the vibration intensity at points MP1 and MP3 does meet the criteria for unrestricted long-term operation of the drive unit.…”

“…The object of research was a bucket elevator, which is a real technical system operating 24/7 in a fuel feeding line under industrial conditions. This elevator, designated for this article as BE#3, has four times the capacity (400 m 3 /h) and three times the drive power (45 kW) compared to BE#1 and BE#2-two twin bucket elevators that were the subject of research presented in [18].…”

“…As highlighted in paper [18], the RMS value is generally considered an appropriate measure for steady-state signals, while the peak value is more appropriate for a signal whose average level is relatively low but does occasionally have pulses [35]. The crest factor is recommended and used in particular by Bruel&Kjaer Co. (Naerum, Denmark) as an indicator for assessing the condition of rolling-element bearings [36].…”

Bucket elevators generally operate on a 24/7 basis, and for this reason, one of the main requirements is their high reliability. This reliability can be ensured, among other things, by assessing the technical condition of drive assemblies and working assemblies and taking appropriate measures. Carrying out diagnostic measurements enables periodical monitoring of those mechanisms. Vibroacoustic methods are usually employed in operating conditions to measure vibration velocity and acceleration at specific points, and are used as diagnostic signals. This paper presents the results of tests of the intensity of vibrations generated in the drive unit of a large industrial bucket elevator. The analysis of the results in the time domain and frequency domain served as the basis for evaluating the suitability of the drive, and thus the elevator, for long-term operation.
