Identification of influence of part tolerances of 3PWR-SE pump on its total efficiency taking into consideration multi-valued logic trees

This paper presents the way of identifying the influence of the tolerance of model pumps (TYPE 3PWR-SE) construction on the total efficiency. The identification of sensitive control dimensions (Value / Tolerance) of examined pumps has been made by means of the multi-valued logic and inductive decision trees. In order to confirm the obtained results, multiple-valued logic trees have been used in the paper according to algorithms for the minimization of individual logic functions. What is more, a specific monotonicity of values of the most key parameters has been determined for the investigated set of pumps having individual specification numbers.
