D型150-100X10多级泵设计.docVIP

摘 要 本次毕业设计是关于的设计。首先对作了简单的概述；接着分析了的选型原则及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的各主要零部件进行了校核多级泵采用计算机设计和优化处理目前，正朝着长距离，的方向发展，从而可以提高泵使用寿命和降低机组噪音近年来出现的就是其中的一个。在的设计、制造以及应用方面,目前我国与国外先进水平相比仍有较大差距,国内在设计过程中存在着很多不足。 本次设计代表了设计的一般过程, 对今后的选型设计工作有一定的参考价值。 关键词：多级泵设计准则校核Abstract This graduation project is about the D150-100X10design of multistage pump. Multistage pump is the transmission capacity of the largest continuous conveying machinery. It has the advantages of simple structure, stable operation, reliable operation, low energy consumption, little pollution to the environment, and is convenient for centralized control and automation, convenient management and maintenance, in the continuous loading condition can realize continuous transportation. The multistage pump is summarized; and then analyzes the multistage pump type selection and calculation methods; and then according to these design criteria and the calculation and selection methods according to the given parameters selection of design; then the choice of multistage pump of main parts and components of the school nucleus. At present, the multi-stage pump are moving towards long distance, low consumption, small direction, which can increase pump life and reduce the noise of the unit pump by computer design and optimize treatment, in recent years the medical pump is one of the. In pump design, manufacture and application, at present our country compared with foreign advanced level still has bigger difference, the domestic in the design of multistage pump process exists many shortcomings. The multistage pump design represents the general design process, the future selection of the design work has a certain reference v Key words: multistage pumpS design rule check 目 录 1绪论 1 1.1多级泵的历史 1 1.2多级泵的分类 2 1.3多级泵的组成 2 2吸入与压出口径的确定 4 2.1 泵的主要参数 4 3部分参数的估算与确定 5 3.1 计算比转数 5 3.2 估算泵的效率 5 3.3 求泵轴功率和电机的选择 6 3.4 轴径和轮毂直径的计算： 7 4水力设计 8 4.1 叶轮 8 4.1.2叶轮出口部分尺寸 12 4.1.3叶片绘型： 14 4.2 导叶 27 4.3. 平衡盘 31 5.强度校核 3
