When the cryogenic vane pump of low specific speed is operating, the cavitation phenomenon often occurs. By the example of a particular cryogenic pump this article considers and estimates the techniques of increasing the suction capacity using computational modeling. The method under consideration allows carrying out research quickly and without costly experiments, which is very important in the modern pump manufacture industry. The work provides examples of the basic approaches to calculating the parameters characterizing the cavitational properties of vane hydraulic machines. Based on the Rayleigh — Plesset model we have constructed particular cavitation characteristics for various models of the cryogenic pump’s liquid end and evaluated the results.
