Разработка проточной части насоса СПГ с повышенными кавитационными качествами

Abstract

Тема выпускной квалификационной работы: «Разработка проточной части насоса СПГ с повышенными кавитационными качествами». Настоящая работа посвящена разработке двух вариантов исполнения проточной части с использованием двухвальной схемы работы с применением планетарного редуктора с целью обеспечения заданных технических параметров насоса отгрузки сжиженного углеводородного газа зарубежного аналога компании «Atlas Copco». В работе решаются следующие поставленные задачи: 1. Анализ мирового рынка СПГ, а также рассмотрение вопроса развития потенциала по наращиванию производственных мощностей российского СПГ в среднесрочной и долгосрочной перспективе. 2. Определение ведущих мировых производителей насосного оборудования, предназначенного в целях производства и транспортировки СПГ. 3. Разработка двух вариантов исполнения проточной части насоса с повышенными кавитационными качествами с построением прогнозных рабочих характеристик на основе гидродинамических расчетов различных методик. В результате выполненной выпускной квалификационной работы разработаны два варианта исполнения проточной части насоса. Проведены гидродинамические расчеты и получены прогнозные рабочие характеристики насоса, не уступающие импортному аналогу. Предложен второй, как наиболее перспективный, вариант исполнения проточной части насоса для разработки рабочей конструкторской документации опытного образца с целью изготовить и провести его натурные или модельные испытания со снятием напорных, энергетических и кавитационных характеристик.

The subject of the graduate qualification work is: “Development of the flow part of the SPG pump with enhanced cavitation qualities”. This work is devoted to the development of two versions of the flow part using a two-shaft operation scheme using a planetary gear in order to ensure the specified technical parameters of the pump for the discharge of liquefied petroleum gas from a foreign counterpart of Atlas Copco. The following tasks are solved in the work: 1. Analysis of the global SPG market, as well as consideration of the development of potential for increasing the production capacities of Russian SPG in the medium and long term. 2. Definition of the world's leading manufacturers of pumping equipment designed for the production and transportation of SPG. 3. The development of two versions of the flow path of the pump with enhanced cavitation qualities with the construction of predictive performance based on hydrodynamic calculations of various techniques. As a result of the final qualification work, two versions of the flow part of the pump were developed. Hydrodynamic calculations were carried out and the predicted pump performance was obtained, not inferior to the foreign counterpart. A second, as the most promising, embodiment of the pump flow part for the development of working design documentation of a prototype with the aim of manufacturing and conducting full-scale or model tests with the removal of pressure, energy and cavitation characteristics is proposed.
