节能型高压汽雾清洁装置机械结构设计及制作 摘 要 本课题工作主要是对节能型高压汽雾清洁装置机械结构进行设计及制作， 该装置使用 220V 外接电源，应用高压水射流清洗技术，来实现对汽车、墙壁 等外表面的清洗。装置主要有泵、喷枪、储水水箱及高压软管等周边设备。在 该装置进行设计、制作时，主要进行了核心部件如泵、喷嘴、水箱的设计选型、 参数计算及材料的选择。其中最关键部件是泵和喷嘴的设计。高压泵是高压水 射流能量的动力源，目前清洗机所用高压小型泵一般采用叶轮泵，考虑到泵的 可靠性和寿命的问题，本设计装置选用单相电动机通过联轴器直接驱动三缸柱 塞泵，体积小，结构紧凑，可有效提高了设计的经济性和实用性；喷嘴的设计、 选取主要考虑到是否满足射流要求、操作要求等。 通过本设计工作完成了主要部件的计算校核，应用PRO/E等软件对该设备 进行三维造型设计，绘制了部件的工程图，并加工制造了该装置。 关键词：高压射流，高压泵，喷嘴 I 节能型高压汽雾清洁装置机械结构设计及制作 Abstract This title is about designing and simulating high pressure gas-fog washing equipment saving power device. This device uses 220 volts power. The high pressure water injection cleaning technology is applied in this device to achieve the cleaning of car and advertisements appearance. The design of the device uses pump, spray nozzle, spray gun, water preserve box and high pressure flexible tubing such devices related. Through simulating the design of this device, I did a selection about device structure, parameters calculation and material to the main portions such as pump, spray nozzle, water box. High pressure pump is the root to supply high pressure water injection power. To wash a car, the small size high pressure pump which is used commonly is piston pump. Considering the reliability and lifespan of the pump, nowadays the whirlpool pump which has not very high slew speed used usually, Spray nozzle is important portion of high pressure injection of device, and is also the key technology of the high pressure water injection. Its application is transferring the pressure of high pressure water to the kinetic energy of injection liquid. That is why t
