Abstract
Vibration in the shaft of a centrifugal pump arises from various factors, including the spacing between clutches, belt thickness, width, and their positioning within the clutch assembly. Vibration serves as a vital diagnostic tool for assessing machinery, offering insights into both motion and translation. Understanding vibrations and analyzing corresponding data are essential for effective maintenance and troubleshooting protocols. By leveraging this knowledge, companies can mitigate downtime, enhance productivity, and extend the operational lifespan of their machinery. Vibration stems from cyclic forces acting upon machine components, triggering energy release within the structure and resulting in oscillations. Excessive vibration not only generates noise but also compromises pump performance and jeopardizes critical components, notably the shaft and bearings. The objective of this study is to monitor and analyze vibration in centrifugal pumps equipped with modified belt connections. Various configurations of belt thickness, width, distance, and positioning were explored. Real-time data was gathered using accelerometer sensors to capture X, Y, and Z-axis values, subsequently converted from analog to digital format. Among the configurations tested, the Outside-Inside belt positioning, with belt dimensions of 6.5mm thickness, 150mm width, and a 40mm distance, exhibited the lowest average vibration value at 8.72mm/s. However, according to ISO 10816 standards, this measurement falls within the unsatisfactory category, indicating the need for further refinement in pump design and maintenance practices.
