description: Theme of graduate qualification work: âCalculation of low-speed centrifugal pump with non-declining characteristicâ. This work is devoted to the study of the influence of geometrical parameters of the flow part of a low-speed centrifugal pump on the shape of the characteristic. Validation of the method of numerical calculation of the viscous fluid of the flowing part of a low-speed pump has been made. The influence of the relative width and relative diameter of the helical bend on the shape of the characteristic was investigated. The influence of the annular bend on the shape of the characteristic is investigated. The influence of positive flow twist at the inlet to the impeller on the characteristic shape and efficiency has been investigated. The influence of geometrical parameters of the impeller on the shape of the characteristic and efficiency is investigated. The flow part of a low-speed centrifugal pump with a non-declining characteristic shape is obtained.
