Cavitation Characteristics of High Speed Inducer Centrifugal Pumps,
Abstract
This report presents results of studies of the cavitation characteristics of high speed inducer-centrifugal pumps. The mechanism of cavitation growth in the pump is described and the most rational matching of the centrifugal rotor and inducer parameters is proposed. Recommendations are given on optimal design of the individual pump components. An estimate is made of the influence of the basic inducer and centrifugal rotor parameters on the first and second critical regimes and the magnitude of the pump head decrease with transition from the first to the second critical regime. A technique is presented for cavitation design of the high speed inducer-centrifugal pump which includes basic statistical data, configuration, and an example of the design of a pump with required Rudnev cavitation coefficient (C sub cr) = or > 4500.
