传统的检定系统中,标准金属量器每次注水都需要根据量器刻线标志,由人工控制阀门关停,耗时费力,且上注水水流量较大,容易产生大量气泡,影响检定结果的准确性。随着汽车罐车检定数量不断增加,对检定过程中的时效性要求不断提高,原检定系统已不能满足检定工作的需求。笔者依据JJG133-2005《汽车油罐车容量检定规程》要求及结合多年的检定经验,在经过调研论证的基础上对检定系统进行了改造,增加了液位传感器、溢流管和回流管等装置,有效
The traditional verification system, the standard metal measuring device each need to mark according to the amount of engraved marking device, controlled by the manual shut-off valve, time-consuming and laborious, and the injection of large water flow, prone to a large number of bubbles, the test results affect the accuracy. With the increasing number of automobile tanker inspection, the timeliness requirements in the verification process continue to increase, the original verification system can no longer meet the requirements of verification work. Based on the requirements of JJG133-2005 Automobile Tank Car Capacity Verification Regulation and combined with many years of verification experience, the author reformed the verification system on the basis of investigation and verification, adding devices such as liquid level sensors, overflow pipes and return pipes ,effective
