铁路罐车结构改变情况下容积检定应对措施

Measures for Volume Verification of Rail Tanker under the Condition of Structural Change

在依据JJG 140—2018 《铁路罐车容积》检定铁路罐车容积过程中发现,JJG 140—2018给出的2种G60铁路罐车参数不能涵盖目前应用的所有G60铁路罐车。同时,根据近几年铁路罐车用户的需求和铁路罐车的不断改进,GL70和GH70A等铁路罐车罐体结构发生了变化,检定结果会出现一定偏差。为了保障铁路罐车容积检定结果的准确性,在介绍这些铁路罐车现状的基础上,提出在检定过程中容积表号字头的选择和测量要点等相关建议。

In the process of verification of volume of rail tankers according to JJG 140—2018 Volume of rail tankers,it is found that the parameters of the two kinds of G60rail tankers given by JJG 140—2018 cannot cover all the G60rail tankers currently used. At the same time, according to the needs of users of rail tanker and the continuous improvement of rail tanker in recent years, the tank structure of rail tanker such as GL70and GH70Ahas been changed, and this leads to certain deviation of verification results. In order to ensure the accuracy of the verification results of the volume of rail tankers, based on the introduction of the current status of these rail tankers, the suggestions on the selection of volume table number and measurement points during the verification process are put forward.
