Resource Efficiency Compromise for Centrifugal Pump

Abstract

Annotation The main characteristics of centrifugal pumps, like many other mechanisms, include resource and efficiency. Often these are two competing parameters - while increasing the first, we sacrifice the second. This is because with an increase in the rotational speed of the pump rotor, the life of the bearings drops rapidly, and the efficiency, on the contrary, increases. There is a need to find a compromise solution, when at the selected value of one parameter the second is maximum.
