一、目前情况分析 我国从1949年开始制造铁路罐车,开始时制造载重为25t,有效容积为30.5m~3的G_3型罐车。随着设计、制造工艺水平的不断提高,相继造出50m~3、60m~3、80m~3的罐车和60t粉状货物罐车。按用途分类,大致可分为粘油罐车、轻油罐车、酸碱罐车以及其他罐车。按结构分类,则可分为有底架及无底架两大类。另外60m~3以上的大容量罐车,都是无空气包结构的。
I. Analysis of the Present Situation China started manufacturing railway tankers from 1949 and started manufacturing G_3 tankers with a carrying capacity of 25 tons and an effective volume of 30.5 m ~ 3. With the continuous improvement of the design and manufacturing technology, 50m ~ 3,60m ~ 3,80m ~ 3 tankers and 60t powder cargo tankers have been built. By use classification, can be divided into sticky tanker, light tanker, acid tanker and other tankers. Classified according to the structure, it can be divided into two major categories: undercarriage and undercarriage. In addition 60m ~ 3 above the large-capacity tanker, are no air bag structure.
