随着不同领域和不同行业的逐渐发展，环境的不断恶化，对生态系统的关注也越来

越多。在如今社会中各大大都市的建设速度越来越快，人们对城市的环保标准也越来越

高。所以，作为洁净的“卫士”的高压清洗车，成为目前最有前途的特种车辆种类。

本文考虑相关高压清洗车的实际急需和无法装载大量的水限制，在普通货车的基础

上进行的改造，改装一种以二类底盘为基额载质量为5T高压清洗车。在本文设计中有取

力器、高压清洗车动力性、罐体、喷头、燃油经济性、阀体、稳定性之数的计算，最终

得出结构稳定和功能良好的高压清洗车。本型号高压清洗车提高了工作效率，不用在公

路建设较多的消防栓，节约了建设的资金。

water,the transformation is carried out on the basis of the ordinary
truck,and a new type of water-sprinkling vehicle is modified based on the second-class chassis
with a load mass of 5t. There are high-pressure water pump, fluid pump, hydraulic cylinder,
higher pressure  cleaning car power, fuel  economy, stab ility  calc ulation, and fin ally  obta in a
high-pressure cleaning truck with stable structure and good function.This type of high-pressure
cleaning car improves the work efficiency,does not need to build more fire hydrants on the
highway,and saves ours construction funds.
