International Journal of Modern Engineering Research (IJMER) Vol.2, Issue.6, Nov-Dec. 2012 pp-4026-4029 ISSN: 2249-6645 Bearing Life Improvement of Centrifugal Blowers by Vibration Analysis B. A. Kardile, Associate Member, IEI, Abstract : This study work is proposed to carry out II. BLOWER STRUCTURAL ANALYSIS vibration analysis of heavy duty centrifugal Blowers Machine vibration has several categories of bearing failure analysis. The life of bearing can be causes that we have discovered after so many repairs, but improved by carrying corrective actions on blower it is useful now to review them to gain more confidence in modifying its accessories like Plumber block to prevent the diagnosis. The actual structure of blower shown in Fig bearing failure. The proposed work is planned in following 1. phases Preparation of measuring instrument for data The Major categories of diagnoses are – collection (PRUFTECK VIBROEXPERT METER) • Design defects Collection of data from various locations on blower • Manufacturing defects surfaces in different directions. Data analysis is done on • Operational stresses the basis of spectral plot, amplitude against frequencies • Maintenance actions with the help of prufteck vibroexpert meter. In comparison • Aging of vibration spectral with experimental actions are carried Design defects are mostly structural related with out under the vibration severity s
