Analysis of the Gear Pump’s Acoustic Properties Taking into Account the Classification of Induction Trees

This paper presents an analysis of selected acoustic properties gear pumps. For this purpose, the characteristics types displacement pumps—gear pumps—are discussed, as well discrete methods identification and classification signals. The basic assumptions noise in reverberation chambers are distribution measurement points using decision trees statistical measured levels was conducted. object for conducted research a pump with undercut tooth profile developed by Wytwórnia Pomp Zębatych Sp. z o.o. Wrocław. Our own indicates that performance units depends on number factors, including, particular, technology quality manufacture geometric parameters toothing. aim analyses presented to determine which microphones has most important impact level determined generated chamber. aimed at ranking importance eight located. To end, induction were developed, results obtained frequency sound pressure ranges prepared. made it possible optimize arrangement chamber without unnecessary each separately.
