【 摘 要 】

The article presents the results of preliminary experimental analyses of damping pressure pulsation by the hydraulic flexible hoses. The tests have been conducted in the form of a complete two-level experiment, having selected the following parameter variables: flexible hose type (1 or 2-wire hose), pressure value in the pressure line, rotational speed of the pump shaft, pressure line length. The acquired curves have been analysed in time domains. Values of pressure line damping in relation to the dominant pressure peaks have also been determined. The aim of the undertaken tests has been to confirm or overthrow the common belief that the pressure line with flexible hose itself is the sufficient damper of pressure pulsation in a hydraulic pump.
