JX01-017@200D多段离心式清水泵结构设计,机械毕业设计全套

内容简介：

毕业设计（或论文）说明书 摘 要 泵作为一种通用机械，在国民经济中各个领域都有广泛的应用。农业的灌溉和排涝，城市的供水和排水都需要泵。在工业的各个部门泵更是不可缺少的。本人此次设计的是 200D 型离心式清水泵。此类泵是利用叶片和液体相互作用来输送液体的叶片泵的一种，输送清水（含杂质量小 1%，颗粒度小于 0.1mm），物理化学性质类似于水的其他液体。它输送介质温度小于 80C ，适用于矿山排水、工厂和城市给排水等场合。 离心泵具有结构简单，系统无需卸压装置，运行安全可靠和性能优良等特点。 本文介绍 200D型离心泵的各部分结构和几何参数对泵性能的影响，分段式多级泵的用途比较广泛，产量也比较大，这种泵实际上等于将几个叶轮装在一根轴上，串联的工作，所以扬程一般比较高，每个叶轮均有相应的导叶。 【关键词】 离心泵 导叶 叶轮 平衡装置 nts 毕业设计（或论文）说明书 Abstract pump is as one kind of general machinery, and all there is the extensive application in each domain in national economy. The agriculture irrigates and draining flooded fields, and the water supply of city and draining off water all needs the pump. Each department pump in industry more cannot lack. What I this time designed is 200Ds mould being at odds with the community or the leadership type clear water pump. This kind of pump is using leaf blade and liquid to interact to carry a kind of liquid vane pump, and carries clear water ( keeping in the mouth the miscellaneous quality small 1%, the granulation is smaller than 0.1mm ), similar other liquid in water of physicochemical property. Its transport medium temperature is smaller than 80, occasions such as is suitable in the mine draining off water and factory and city plumbing etc. It is simple that the centrifugal pump possesses the structure, and the system need not the decompression device, the characteristics such as to run safe and reliable(ly) with the function fine etc. This book is introduced the various part of structure of 200Ds mould centrifugal pump and how much influences to the pump function of parameter, extensive, and output is also fairly greatly, in fact this kind of pump is equaled to to load several impellers on an axle, tandem work, so the lift is generally fairly higher, that every impe ller all has corresponding(ly) leads. 【
