Abstract

The main tool for assessing the quality of elements of hydraulic systems is a test bench that simulates the modes of operation of the equipment. The requirements for the stands are becoming more stringent in accordance with the promising directions in the development of hydraulic systems and elements of their components. To perform studies of the vibroacoustic characteristics of products, the stand must have low levels of intrinsic noise of these parameters. On the example of a specialized pipeline, pump measuring stand, a number of technical solutions are given that make it possible to deal with sources of intrinsic noise in the measuring section. The paper provides computational justifications for the effectiveness of the proposed technical solutions. A complex of experimental studies is being carried out, confirming the set parameters for reducing their own vibroacoustic bench noise. The operating modes of bench equipment are determined to ensure maximum reliability of the results of tests of elements of hydraulic systems. The ways of further development of the material and technical base of the pipeline, pump measuring stand are outlined.
