Hydraulic Calculation and Structural Design of the Single-Stage Centrifugal Pump Impeller

Centrifugal pumps are widely used in various industries such as manufacturing, agriculture and firefighting due to their versatility. They are based on the principle of creating centrifugal force by a rotating impeller, which ensures the movement of liquid from the suction point to the discharge point. Design methods are based on the theory of one-dimensional homogeneous flows and hydraulic laws. This study focuses on designing impellers for centrifugal pumps with the aim of creating an efficient design that meets performance and head requirements. To achieve this, fundamental principles of fluid mechanics and empirical equations for one-dimensional flows are utilized. The culmination of the work is the study and analysis of various methods for calculating the hydraulic characteristics of centrifugal pumps, which helps to identify their advantages and limitations and select the most suitable method for a particular task. Efficient application of such methods simplifies and speeds up the pump design process, enabling engineers to develop new models and improve existing ones more quickly.
