正元技术服务组深入现场解决脱碳程控阀故障作者/来源:阳煤正元集团 日期: 2020-12-24 点击率:13 正元化肥技术服务承接项目湖北新鄂西化工PSA脱碳装置阀位检测采用电磁装置,其一段R塔110阀阀检故障,不能显示阀门开关状态,为装置运行留下隐患。技术服务组根据以往经验分析,认为是油缸内装配的磁铁损坏导致,由于在运行状态下磁铁不能检查更换,故障一直未能处理。装置停车后对该阀检进行检查并更换磁铁及触头,经调试仍不能正常指示阀位,但将磁铁与触头接触时,阀位指示报警指示正常。 针对此种情况,技术服务组分析可能是由于触头与磁铁相距较远,磁力衰减造成触头不能感应导致。按照分析判断,技术服务组对可能造成距离增加的因素进行逐一检查后发现,触头的铜质护套壁厚较正常的5mm厚2mm,由于厚度增加导致触头与磁铁距离增大并且不易穿透,导致阀位检测失效。 技术服务组更换了护套后,调试结果显示正常,至此故障得以解决,为装置运行消除了隐患。
