Повышение долговечности машин барабанного типа

Abstract

Данная работа посвящена исследованию механических параметров и процессу гидроэрозионного изнашивания материалов рабочих поверхностей машин барабанного типа. В результате выполненной работы: 1. Проведены теоретические исследования машин барабанного типа: - определены конструктивные размеры элементов корпуса, выполнены расчеты прочностных и деформационных характеристик конструкции сушилки барабанного типа; - определены напряжения Мизеса и деформации рабочей поверхности в зависимости от нагрузки, размеров отверстий и материала рабочей поверхности барабанного грохота. Сделан вывод о возможности использования конструкции поверхности барабана для заданной нагрузки. 2. Проведены лабораторные испытания на гидроэрозионный износ образцов материала просеивающей поверхности барабанного грохота. Сделан вывод о возможности использования материалов образцов для изготовления рабочей поверхности барабана. Выбор и обоснование конструктивных параметров машин барабанного типа в зависимости от технологической нагрузки направлено на совершенствование технологии и оборудования в машиностроении. Результаты испытаний могут быть использованы при проектировании машин барабанного типа.

This work is devoted to the study of mechanical parameters and the process of water erosion wear of materials on the working surfaces of drum-type machines. As a result of the work performed: 1. Theoretical studies of drum-type machines have been carried out: - the structural dimensions of the housing elements were determined, calculations of the strength and deformation characteristics of the drum-type structure were performed. - von Mises stresses and deformations of the working surface are determined depending on the load, the size of the holes and the surface material of the drum screen. A conclusion is made about the possibility of using the drum surface design for a given load. 2. Laboratory tests for hydroerosive wear of samples of the material of the screening surface of the drum screen were carried out. A conclusion is made about the possibility of using sample materials for the manufacture of the working surface of the drum. The selection and justification of the design parameters of drum-type machines depending on the technological load is aimed at improving technology and equipment in mechanical engineering. The test results can be used in the design of drum-type machines.
