一、原因分析金属罐日常使用中出现较大差量时,一般都要对差量原因进行分析。经大量调查、分析发现,差量除金属罐自身计量检定造成的误差之外,还有来自生产工作的环节,包括作业过程安排不合理、操作人员的生产操作不规范、操作规程没有考虑到准确计量的因素等。这些因素直接导致原油在罐内混合不均匀,无法采集具有代表性的样品;油罐内温度不均匀,测温数据不具有代表性;作业安排或操作失误导致计量数据失真;收油前后管线充满度不一致,进罐量欠缺或偏多等一系列的问题。
First, the analysis of the reasons for the daily use of metal cans larger differences, the general reasons for the difference should be analyzed. After a large number of surveys and analyzes, it was found that the difference in addition to the error caused by the metal tank’s own metrological verification also comes from the production work, including the unreasonable operation of the process, the non-standard operation of the operator and the failure of the operation procedure to take into account the accuracy Measurement factors. These factors directly lead to uneven mixing of crude oil in the tank, can not collect representative samples; uneven temperature in the tank, the temperature data is not representative; operating arrangements or operational errors lead to measurement data distortion; Inconsistent degrees, into the lack of or too much can of a series of problems.
