关键字:ABB阀门定位器 http://www.abb-positioner.com/ ABB阀门定位器具有警报功能,不同的故障所显示的警报内容也会有所不同,如果你看到报警HMI显示代码为M051.003,说明这个故障具有严重性的警报,是需要维护的优先级。 ABB阀门定位器出现这个故障,如果控制阀确实保持稳定的控制行为,定位器会持续监控控制位置定位不稳定报警将被激活。控制阀没有跟踪设定值要求信号,这将影响到过程控制循环。出现这些问题的原因主要是执行器行为不稳定或振荡,这可能是执行器或管道中从ABB阀门定位器到执行器的空气泄漏或定位器控制参数不正确。 针对这一问题,建议检查执行器是否有任何明显的泄漏,并采取必要的纠正措施。执行泄漏检测测试以确认没有进一步的泄漏,例如内部执行器腔密封泄漏,这在双作用执行器中是可能的。一个简单的方法,检查漏气是通过HMI将定位器切换到手动模式。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处:http://www.abb-positioner.com/a/xwdt/97.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-pointer-lock allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&dt=1594971235695&bpp=10&bdt=52&idt=45&shv=r20200715&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=5600338422535&frm=23&ife=1&pv=2&ga_vid=349050421.1594971236&ga_sid=1594971236&ga_hid=119142801&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=8&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=2300886825066071&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8220&bc=31&ifi=0&uci=0.dapfbnw286nt&fsb=1&dtd=73" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.dapfbnw286nt" data-load-complete="true"> |
