管线泄露对流量计计量影响与解决办法

 1 WENTIDETICHU

    某油库计量间安装有10台流量计,其中LL-300型腰轮流量计7台,LJB-S3型Simith刮板流量计3台。2003年计量间搬迁重建,标准体积管安装完毕后进行了检定,检定结果合格;用标准体积管对3台Simith刮板流量计进行在线检定时,发现其基本误差超过允许误差范围,采取器差调整后,基本误差在允许范围内,重复性误差仍不符合要求。如某油库3#流量计在2003年4月6日的检定过程中其基本误差、重复性误差均不合格,对3#流量计的器差进行调整后,于4月16日再次进行检定时,其基本误差在允许范围内,但重复性误差仍超过标准规定。通过对体积管、流量计、阀门等装置及现场标定工艺进行认真地分析,反复查找原因,认为造成流量计复现性误差超标的主要原因是由于泄漏所致。

    根据油库计量工艺流程,通过标定流程的切换进行相关性排除,认为各来油线7台腰轮流量计的出口标定阀对外输3台simith刮板流量计检定结果基本无影响,主要是3台同时并联运行的Simith刮板流量计之间的阀门泄漏造成影响。通过反复试验,认为外输3#流量计受泄漏影响程度***大。因此,下一步将重点对3#A阀门进行重点检查,对可能存在泄漏的1#B、2#A、2#B阀门进行检查。根据现场工艺流程实际情况,分以下步骤进行判断:
