description: The subject of the graduate of qualification work is Â«Design of multistage centrifugal pumpÂ».
The given work is devoted to the design process of multistage centrifugal pumps.
The purpose of this work is to study the design methods of centrifugal pumps, construction of the first stage impeller and its vane-type discharge.
The final qualifying work contains seven chapters. In the first Chapter, we consider the method of designing the first stage impeller for a centrifugal pump, determining its main dimensions and then profiling its blades. In the second Chapter, the method of designing a vane-type tap for the constructed impeller is considered. In the third Chapter, cavitation qualities are calculated. The fourth and fifth chapters consider the axial and radial forces acting on the pump rotor. In the sixth Chapter, bearings for the pump rotor are calculated. The seventh Chapter presents calculations of the critical velocity of the shaft.
The subsequent use of skills obtained during the performance of the final qualification work can be used in the design of subsequent centrifugal pumps.
