Abstract :
This research is motivated by the results of the author's observations of problems
related to maintenance of water injection pump assemblies. The aim of this
research is to improve predictive maintenance procedures by analyzing vibrations
using an online system. This seeks to lower the risk of equipment failure, lower
maintenance costs, and increase overall operational availability. The approach
used in this research is to apply a periodic monitoring method to equipment by
analyzing vibrations (Vibrations Analyzer). The data was collected using
observation data techniques, interviews, documentation sessions and analyzing
vibration data via a vibration system (SKF Multilog IMX-S). The aim is to provide
practical guidance to companies to optimize approximate maintenance practices.
Based on the data findings, the results of this research showed that the Water
Pump pump first showed signs of damage in the form of mechanical looseness in
the pump base plate and misalignment of the pump during high vibration
conditions. After repeated measurements of the vibration height, the bearing on
the Water Injection pump with a vibration system (SKF Multilog IMX-S) was
damaged, resulting in an unsatisfactory condition. This is caused by previous
mechanical looseness and misalignment; even if the amplitude is good, the bolts
on the pump base plate will loosen if not checked. Potential to increase the
frequency of misalignment.
