摘 要
 本論文提出的泵屬于流體機(jī)械，是一種將原動(dòng)力所做的功轉(zhuǎn)化為被輸送液體的壓力勢能和動(dòng)能的流體機(jī)械。本論文是關(guān)于清水離心泵的機(jī)械設(shè)計(jì)。首先介紹離心泵的工作原理及其基本組成的六大部分：葉輪、泵體、泵軸、軸承、密封環(huán)、填料函。清水離心泵在實(shí)際生活當(dāng)中的應(yīng)用亦有所介紹。
  論文講述了一般清水離心泵的設(shè)計(jì)過程，由給定的設(shè)計(jì)參數(shù)進(jìn)行水力計(jì)算得出離心泵主要部分葉輪、葉片的設(shè)計(jì)參數(shù)，從而確定葉輪、葉片的尺寸大小和外形結(jié)構(gòu)。對蝸室和擴(kuò)散管也有所提及。對如何選取離心泵的與電機(jī)相連部分的聯(lián)軸器進(jìn)行了詳細(xì)的描述。軸是離心泵的動(dòng)力傳入部分，本論文對軸的選材到設(shè)計(jì)計(jì)算都有提及，由功率確定電機(jī)的型號(hào)，從而確定軸的最小軸徑。如何選取軸的配套部件軸承的也做了介紹。

Abstract
 The pump in this paper is belong to fluid machinery, is a kind of fluid machinery that can make the work of motive power become the pressure potential energy and kinetic energy of the carried fluid. This thesis is about the mechanical design of water centrifugal pump. First, it introduces the principle of the centrifugal pump and its’ six basic large parts : impeller, pump body, bearings, shaft ,gasket ring and packing. It also introduces the application of water pump in practice.
 This paper introduces the design process of the water centrifugal pump .By the given design parameters, it can determine the size and structure of the main part of the impeller and blade. The spiral housing and diffusion tube have also been mentioned in this paper. It has a   detailed description of how to select a coupling which connects the pump and the motor. Axis is the part of the incoming power to the centrifugal pump. This paper has mentioned how to choose the material of the axis and the design calculations as well. The type of motor is determined by the power, so it can determine the minimum diameter of the axis. It also introduces how to choose the right bearings.
Keywords: centrifugal pump  design  hydraulic calculation  capability
