Influência de variáveis de processo no nível de vibração de um conjunto motobomba de grande porte

Abstract

It is known that process variables influence the level of vibration of machines, especially where the same system should operate in several different scenarios. In this case, a pipeline must operate with a wide variety of products at different flow rates. The initial objective of this study was to quantify the impact of different operating conditions on the level of vibration of motor and pump of an oil pipeline. But in the end, the study accomplished a more interesting goal, which was, the possibility to provide the expected level of vibration based on the flow rate and density of the pumped product. In this way, it is possible to identify, in real time, whether the operating conditions of flow rate and density are contributing to an increase in vibration and possible damage to the equipment. Furthermore, it will become easier to differentiate between potential faults and harmless vibration increases caused by changes in operating conditions.
