NUMERICAL CALCULATIONS OF THE IMPELLER OF A CENTRIFUGAL PUMP USED IN THE OIL AND GAS INDUSTRY

Pumps are used to transport liquid products within technological installations inside and outside any petrochemical industry enterprise. Pumps are also used in drilling oil and gas wells. The share of centrifugal pumps at field oil treatment facilities and refineries can reach more than 80%. Centrifugal pumps are characterized by high performance, simplicity of design, compactness, versatility, uniform flow, high efficiency (for large units – 0.75-0.9), etc. The main element of a centrifugal pump is an impeller with curved blades mounted on a shaft and driven by an electric motor. In this regard, further improvement of the design of the centrifugal pump, including its main element – the impeller, as well as the use of modern computer-based calculation methods in this process is an urgent task. The design of the wheel is largely determined by its speed coefficient ns. With an increase in the speed coefficient, an increase in the relative width of the impeller blade at the outlet and a decrease in its relative outer diameter, t, e. the impeller is converted sequentially from radial to axial. To determine the speed coefficient when switching to a multistage pump, the pressure created by one stage should be divided by the number of stages. This fact is not reflected in the source, which caused difficulty in the calculation. Special attention should be paid to improving the design of centrifugal pumps and the use of advanced computer calculation methods. Python is one of the most popular general–purpose programming languages. It is among the fastest available programming languages in the world and is used by software engineers, mathematicians, data analysts, scientists, network engineers, students and accountants. An algorithm and a program in Python were compiled and the result was obtained using the source data. The practical significance of the research lies in the fact that the results of the work performed on the topic "Numerical calculations of the impeller of a centrifugal pump used in the oil and gas industry" can be used as a base for theoretical research, analytical and design activities of authors studying this area. The second aspect of the practical significance of this study is the possibility of using the results of the study within the framework of the topic "Numerical calculations of the impeller of a centrifugal pump used in the oil and gas industry" in order to develop the mechanism of functioning of the object under study.
