Tests using mixed-oxidant solution instead of oxidizing biocides (chlorine or bromine) for cooling tower maintenance

The operations history of these two large

It also shows the dramatic effect that mounting has on commonly used high frequency measurements such as Spike Energy and PeakVue that are used for early warning of bearing and gear faults

By performing thorough annual inspections as described

05-04: Natural Frequency Characteristics of Drive Shafts Fills The driving force was oftenFor rotating machinery utilizing drive shafts, it is important to operate at a speed sufficiently lower than the drive shaft's natural frequency to prevent destructive vibration. In this paper, the theory of determining the shaft's natural frequency is presented as well as methods for empirically testing a shaft's natural frequency. Vibrations levels in the region of the natural frequency are empirically determined for composite drive shafts and
