目前我国的运用罐车品种有20余种,约2.8万多辆,其中进口罐车约占20%左右。由于部分进口罐车某些原结构不能满足国内需要,或出于部分罐车原结构设计不合理,或由于技术进步原设计不适应目前需要,在厂修时需要进行加装改造。在检修中我们发现罐车结构除部定的21个技术改造项目外,在结构设计上还存在一些问题需要改造,现分述如下。 At present, there are more than 20 kinds of tankers in China, about 28,000 vehicles, of which about 20% are imported tankers. As some of the original imported tanker can not meet the domestic needs of the original structure or part of the original structure of the original tanker design is not reasonable or because the original design of technological advances do not meet the current needs of the factory repair need retrofitting. In the overhaul, we found that there are still some problems in structural design that need to be reformed in addition to the 21 technical renovation projects of the tanker structure.
