CURRENT STATE AND PROSPECTS FOR DEVELOPMENT OF ENERGY PERFECTION OF VANE PUMPS

Abstract

Оne of the most important problems of the XXI century is the problem of energy saving. It covers all spheres of human activity. The use of energy saving of pumping equipment is also very relevant. Pumps of various types and different designs are widely used in general engineering, military and aerospace industries. Ensuring high energy characteristics of pumps is one of the most important parts of energy saving problems. The results of the research showed that it is very important to improve energy performance. Works are carried out in all branches of industry and for all types of pumps. Improvement of energy properties is performed in the following direction: Development of new mathematical models describing in more detail the physicss of the working process for each specific type of pump; use of ANSYS software. But in modern literature there is no information about the increase in energy characteristics of low fluid flow low-speed inducer-centrifugal pump liquid propellant rocket engine. Therefore, such research is very important and their results will be in demand in the scientific community. There is no comprehensive approach to identifying ways to increase energy characteristics for low fluid flow low-speed inducer-centrifugal pump liquid propellant rocket engine. In turn, the high energy characteristics of the units of the fuel and oxide supply system units high energy characteristics of the upper stages of the launch vehicle, And the weight of the payload which deduces launch vehicle largely depends on them. It is necessary to conduct a comprehensive experimental-theoretical study during which methodological tools will be developed that allow in a short time and with high accuracy to increase the energy characteristics of low fluid flow low-speed inducer-centrifugal pumps liquid propellant rocket engine upper stages launch vehicle.
