采用高压水射流清洗,是铁路车辆零部件清洗工艺的一大改革。目前国内一般多用火碱(NaOH)热水(水温80°～85℃)冲(煮)洗。这种清洗方法存在着质量不稳定,原材料消耗大,成本高,污染严重,对身体健康有害和腐蚀车辆零部件的缺点。近年来,国外一些工业化国家采用高压水射流清洗新工艺,取得显著效果。国内也有少数单位进行了高压水射流清洗的研究试验。但由于对技术参数的选用,喷嘴、管路等主要 The use of high-pressure water jet cleaning is a major reform of the railway vehicle parts cleaning process. At present, the general use of caustic soda (NaOH) hot water (water temperature 80 ° ~ 85 ℃) red (boil) wash. This cleaning method has the drawbacks of unstable quality, high raw material costs, high costs, serious pollution, health hazards and corrosion of vehicle parts. In recent years, some foreign industrialized countries have adopted high-pressure water jet cleaning technology and achieved remarkable results. A small number of domestic units also conducted high-pressure jet cleaning research. However, due to the selection of technical parameters, nozzles, piping and other major
