Abstract

Abstract Centrifugal pumps are used in most industries. In particular, they are effectively used in the technological processes of oil production to create reservoir pressure at oil fields. Due to increasing demand for petroleum products, there is a need to improve such pumps to increase reservoir pressure by increasing their pressure. The research considered the possibility of improving the centrifugal pump impeller design by changing its blade system. It is theoretically possible to increase the pump head by changing the blade outlet angle at the impeller outlet β2 to 75°. The design of additional wedge-shaped blades of the second tier of the impeller was developed to reduce some additional hydraulic losses zones. They made it possible to stabilize the fluid flow in the impeller intervane channels, to reduce additional hydraulic losses. In the research, the impeller head was increased up to 26.7% for the proposed design impeller compared to the standard one. The research was performed with a comprehensive analysis of the pump installation life cycle cost. Thus, the development of new ones and the upgrading of pumping installations rooted in the industry with the aim of increasing the head is possible while achieving the minimum pump installation life cycle cost.
