Abstract

Vibration analysis is a technique for analyzing vibration spectrum of individual machine componentsand identifying its causes and extends of failures. The method of vibration analysis is not only minimizes the need for extensive, but makes it possible to detect developing problems which are out of the range of human sense of touch and hearing. The Objectiveof this work is to study the problems results in the failure of pump and suggest some better maintenance strategiesto improve MTBF (Mean Time between Failures) of the pump and the motor and to reduce maintenance costby finite element analysis using ANSYS R14.5 software. Results have been discussed and found thatparallel misalignment of pump-motor coupling and defects in pump foundation lead to excess vibration. Required actions were performed andthe vibration at the drive end and non-drive end of the motor has been reduced by 30.5 % and 29.4 % respectively.
