Digital System for Dynamic and Vibration Analysis of a Centrifugal Pump Using the Teknikao Sdav Software: A Case Study

Abstract

The purpose of the paper is to explain how the measurement and vibration analysis software works. A virtual example and a real example were used, defining their initial configurations and analyzing the graphics resulting from the analysis from the vibration analysis software and thus presenting the results of both tests. Understanding how to operate the vibration measurement equipment and analyzing the data obtained from a previously established configuration, this learning about the operational knowledge of dynamic systems is extremely important because the problems become simple to be solved. The analysis was carried in a virtual and real situation, of the centrifugal pump motor vibrations in the SDAV software made available by the Technical website. The problem analyzed was the rolling of seven rotating spheres, this defect fits as a mechanical system with gap defect and with an intensity of one hundred percent. These settings are the parameters adopted to determine the frequency limits of the defect, the resolution of the graph and the number of readings to be taken. When starting, the software will perform all the analysis and measurement of the defect, returning the results in graphs. For the calculation of useful power, it is known that the electrical frequency was thirty-three hertz (33 Hz), which multiplied by sixty, the approximate value of two thousand revolutions per minute (2000 RPM) was obtained. According to the results shown in the graphs, the functioning of machine is excellent, is in perfect condition for use, not presenting light or serious failure.
