往复式喷雾泵站的设计 摘要 喷雾泵站是采煤工作面的重要设备，在减小煤尘与瓦斯的危险和改善工作面的环境上起着重要的作用。喷雾泵站主要应用于采煤机的喷雾除尘，是采煤工作面喷雾系统的主要组成部分。喷雾泵主要由由电动机，减速器，曲轴，连杆，十字头，柱塞，泵体组成。设计的任务主要是对喷雾泵进行设计并进行必要的校核。本首先介绍了喷雾泵的结构和特点，然后根据压力与流量的要求选择电动机和，进而对减速器，曲柄连杆机构，泵体进行设计并且对各个部件进行强度校核。设计的内容主要有方案的选定，减速器的设计，泵的结构形式的选择，泵体的设计，曲柄连杆机构的设计，十字头的设计。该喷雾泵结构紧凑，占地面积小，符合采煤工作面的要求。关键词：喷雾泵 曲轴 减速器 曲柄连杆机构 Reciprocating pump design Abstract Water pump station is an important equipment in the coal face.It plays an important role not only in redusing the danger of dust and gas concentrations but also in improving the environment of the working surface. water pump station is mainly applied in the mist spray and aspirating of coal cutter.It constitutes the vital part of the whole aspirating system of the coal face. water pump is composed of motor, speed reducer ,crankshaft, connecting bar, crosshead, piston, and pump body. Its main task is devised to carry on the design to water pump and make the necessary intensity checking of it. In the first place,this paper introduced development history、the structure and characteristics of water pump. Afterward, it chose the speed of the motor and the main parameters of pump according to the pressure and flux requirement. then designed the speed reducer, connecting rod and pump body,furthermore checked intensity of every part. The main content included the choice of programme, the design of the speed reducer,the pump body, the connecting rod,and the crossheadthe, as well as the selection of the structural style of the pump. The structure is compact ,and the water pump covers small area.It accord with the need of the coalface. key words: Spray pump; crankshaft; speed reducer; Crank rod system; 目 录 第一章 绪论 1 1.1 喷雾泵的发展历史 1 1.2 往复泵的主要特点 1 1.3 本设计喷雾泵站的介绍 2 1.3.1 喷雾泵站的组成 2 1.3.2 喷雾泵站的用途 3 1.3.3 喷雾泵站的工作原理 3 第二章 方案的选定 4 2.1 方案的提出 4 2.2 方案的比较与选择 5 第三章 电动机及喷雾泵参数的选择 6 3.1 电动机的选择 6 3.2 喷雾泵的参数选定 6 第四章 减速齿轮的设计 7 第五章 轴的设计 11 第六章 曲轴的设计 15 6.1 曲轴材料的选择 15 6.2 曲轴结构尺寸的确定 15 6.3 曲轴的平衡 17 第七章 连杆
