离心泵及加工工艺.docVIP

摘 要 本次设计是对发动机水泵的设计及工艺工装设计。共分为 章，水泵的设计：包括水泵的设计参数流量、扬程（扬程近似等于压力）、转速，设计水泵的轴、叶轮、泵体、等部件，然后对其部件进行校核。水泵泵体的工艺规程设计由加工工艺原则可知，对所加工工艺的部件的零件图的加工等级，经济精度、来确定加工方法，如端面的车，孔的钻、镗等加工方法及加工工序的确定，选择加工设备与工艺装备及确定切削用量时间定额。工装方面主要是根据工艺的加工程度，经济，方便情况来确定所用夹具的类型，选择定位元件，误差等方面设计计算。并附有相关的设计尺寸图示，零件图等。本设计虽以加工工艺，工装为主，但对泵的设计也作了详细的说明， 本设计在设计内容中所涉及的问题比较详细的说明计算， 关键词 叶轮，泵轴，蜗壳，加工工艺，专用夹具，定位，夹紧，误差 ABSTRACT The engine design is the design of pumps and process equipment design. Is divided into chapters, the design of pumps: the design parameters, including pump flow, head (approximate equivalent to the pressure head), rotational speed, the design of water pump shaft, impeller, pump body, such as components, and then check its components. Process water pump body design principles from the processing technology, we can see that for the process map parts of the components of the processing level, economic precision, to determine the processing methods, such as the end of the car, hole drilling, boring, such as processing methods and processes the identification, selection of processing equipment and process equipment and to determine the amount of time cutting fixed. Tooling area is based mainly on the degree of processing technology, economic, and convenient to use the situation to determine the type of fixture, select the positioning components, and other aspects of design and calculation errors. Associated with the design size of icons, such as parts diagram. Although the design process, tools-based， but also made the design of pump detail, ???? The design in the design of the content of the issues involved in a more detailed explanation. Keywords impeller， shaft， volute， processing technology， a dedicated fixture， positioning， clamping， error.  目 录 摘 要 I ABSTRACT II 第1章 绪论 1 第2章 发动机水泵的设计 3 2.1泵的主要参数和结构方案的确定 3 2.1.1提供设计的数据和要求 3 2.1.2确定泵的总体结构形式和泵的进出口直径 3 2.1.3 计算比转速 ,确定级数 3 2.1.4 估算水泵的效率 4 2.2泵轴颈和叶轮轮毂直径的确定 4 2.3叶轮主要尺寸的确定 5 2
