介绍了腰轮流量计的基本结构和安装要求,分析了腰轮流量计在现场使用中存在的问题,包括流量计规格选择不当,计量腔中的气体未及时排放,表头的计数器齿轮未定期润滑,现场检定随意采用非相应流量计型号和压力等级的流量计表头进行更换,实际工况与检定工况条件不符,流量计旁通管道截止阀泄漏,以输油泵铭牌上的额定流量核查流量计的流量,新建管道中残留的焊渣和杂物进入流量计的计量腔,对流量计检查不全面,档案资料不齐全等,基于上述问题提出了相应的管理措施。
This paper introduces the basic structure and installation requirements of the flowmeter, analyzes the problems existing in the field of the flowmeter, including improper selection of the flowmeter, gas emission in the measuring chamber, exhausting of the meter counter gear Lubrication, on-site verification free to use non-corresponding flowmeter type and pressure grade meter header replacement, the actual conditions and test conditions do not match the flowmeter bypass valve leakage check valve to the pump nameplate rated flow check Flow meter flow, the new pipeline residue and debris into the flowmeter metering chamber, the flowmeter inspection is not complete, file information is not complete, the above problems based on the proposed management measures.
