User Manual. - Kaluga: 2008. - 70 s. A mathematical model has been developed and a program has been created for the calculation and design of a high-speed screw centrifugal pump . In addition, the program is also used to calculate the centrifugal stage of the general industrial pump. The choice of parametric and functional constraints . is justified Provides the necessary background data. The parameters of the flow cavity are optimized according to several quality criteria. The calculation and design program on the PC operates in the Microsoft Excel environment. The manual is intended for specialists involved in the calculation and design of screw-and-centrifugal pumps and can be useful for students of the specialty "Hydromachines, hydraulic actuators and hydraulic pneumatics", performing diploma design.
