4 Conclusion
Vibration could affect different parts or segments of the pumping aggregate and therefore it is need to analyze the vibrating. In order to avoid highly nonlinear analytical solution in this article soft computing approach was used since the model does not require internal knowledge of the vibration model. It is enough to collect the experimental input/output data pairs and to train the soft computing model. In this study the measuring points were ranked based on their influence on the pumping aggregate. Examination of pumps vibration phenomenon provides the data about the vibration magnitude and its frequency components as well as their change with respect to the operating parameters. Hydraulic vibrations are hard or almost impossible to avoid. Hydraulic processes which happen in pumps are complex and non-stationary by the rule. For description of such processes it is possible to form mathematical models, whose evaluation is performed after very comprehensive, expensive and long-lasting researches.
