Application of Alternative Method for the Detection of Failures in Rotodynamic Systems

The main cause of an engine failure due to overheating is the increase in current, which, when increased, causes a decrease in speed. This research presents a current and velocity analysis using sensors as an alternative method for detecting faults. A data acquisition board and a development environment for obtaining information is sufficient to achieve the interpretation of graphs. Three studies were carried out in the simulation bank with different loads, which were unloaded, unbalanced and balanced in order to observe the operation of the engine under different operating conditions. With the graphical analysis the reliability of the proposed method was verified, which is offered as an alternative of analysis of rotodynamic systems.
