本文拟从检定方法的规范性与适用性入手,对加气机计量溯源方法进行探究。一、加气机检定过程中的规范性要求1.加气机检定气体泄放要求JJG996-2012《压缩天然气加气机检定规程》在“7.1.2检定介质”条款明确要求:检定完毕后的气体泄放,应按GB50156的规定进行。查阅GB50156-2012《汽车加油加气站设计与施工规范》可知:“一次泄放量大于2m~3(基准状态),泄放次数平均每小时2次~3次以上的操作排放,应设置专用回收罐”。以检定小流量加气
This article intends to start from the normativity and applicability of the verification method to probe into the measurement method of gas filling machine. First, the filling machine test process of the normative requirements 1. Gas filling machine test gas release requirements JJG996-2012 “CNG filling machine test procedures” in the “7.1.2 test medium ” Clarification of the requirements of the provisions: test is completed Gas discharge after the GB50156 should be carried out. Check GB50156-2012 “car refueling stations Design and Construction Code” shows: “a discharge of more than 2m ~ 3 (baseline status), the average number of times per second relief discharge more than 3 times the operation of emissions should be set up Recycling tank ”. To test a small flow of gas
