Abstract
The paper, using the example of an external gear pump, considers the solution of the problem of determining the node for separating the source of oscillations and the system of elements of the flow path is considered in order to simplify the study and analysis of hydrodynamic processes behind the source of oscillations. To separate the source of oscillations and the system of elements of the flow path, an experimental approach is used, during which the characteristic of pressure pulsations according to the “tooth” harmonic is determined behind the pump interacting with the serial RLC-circuit. An experimental study using dynamic analogies, methods of classical logic and methods of circuit theory made it possible to determine the connection node of the oscillations source and the system of elements of the flow path on the equivalent circuit, and in the graphic image of the flow part of the pump - to determine the corresponding section.
