IMPROVING THE PERFORMANCE INDICATOR OF CENTRIFUGAL PUMPS

Abstract

This article is devoted to the research and development of methods to improve the performance of centrifugal pumps. Centrifugal pumps are key elements in various industrial and technical systems, ensuring efficient transportation of liquids. This article reviews the operation of centrifugal pumps, shows the scheme of the pumping part of the centrifugal type equipment, the scheme of the cantilever type centrifugal pump and describes their main components. Further, the factors affecting pump performance, including fluid viscosity and operating conditions, are analyzed, and methods for improving performance are described in detail, including design optimization, the use of new materials and modern technologies, as well as speed control and monitoring of pump condition. The advantages and disadvantages of centrifugal pumps are noted, the concept of what the operation of this equipment is based on is given, and the fields of application of centrifugal pumps are considered. In order to improve the operation of pumps, the article includes a table showing the existing problems in the operation of the pumps described by the author, the correction of which will lead to positive results, namely, an increase in quantitative and qualitative performance indicators. Further, in the article, a color diagram is shown, which shows the share distribution, that is, the percentage of damage to the structural elements of centrifugal pumps. To improve the reliability and efficiency of operation of centrifugal pumps, the article discusses in detail two ways to solve this task. The first way to solve the problem is the development and manufacture of new, namely more advanced pumps in design, which most often requires significant financial costs, and the second way was noted the modernization of already functioning equipment, which allows you to reduce your own costs and thereby ensure the implementation of energy saving programs. Based on the analysis and the examples considered, it is concluded that an increase in the performance of centrifugal pumps can lead to a significant improvement in efficiency and cost reduction.
