摘　　要：电磁流量计作为流量测量的仪表,广泛应用于导电液体、水和污水、高温和腐蚀性介质的测量。其中衬里设计和材质正确选择、衬里工艺以及衬里的检验方法,都对衬里本身使用寿命以及衬里和电极之间的密封性起到了重要作用。针对常见的橡胶、PTFE、PFA和PEF衬里,从设计、工艺、材料性能、检验等方面进行系统阐述,为确保衬里设计能够达到预期使用寿命和可靠密封。本文重点研究材料和工艺,以确保衬里能够应对各种复杂的工况。Electromagnetic flow meters,as flow measurement instruments,are widely used in the measurement of conductive liquids,water and sewage,high-temperature and corrosive media.The correct selection of lining design and materials,lining process,and lining inspection methods all play an important role in the service life of the lining itself and the sealing between the lining and the electrode.For common rubber,PTFE,PFA,and PEF linings,a systematic exposition is conducted from the aspects of design,process,material performance,and inspection.To ensure that the lining design can achieve the expected service life and reliable sealing,the focus is on researching materials and processes to ensure that the lining can cope with various complex working conditions.
