关键字:ABB阀门定位器 http://www.abb-positioner.com/ ABB阀门定位器和调节阀的搭配使用才让执行机构发挥出作用,但是操作不当,ABB阀门定位器会引起调节阀震荡,下面看看都有哪些原因。 1.ABB阀门定位器到调节阀的输出气路漏风; 2.DCS整定参数PID不合适,调节阀室内自控波动,改为手动控制调节阀不波动; 3.ABB阀门定位器位移传感器坏,在某一个点位移传感器故障,会出现ERROR12故障报警,定位器自动复位,3s后恢复,期间定位器不输出风压,调节阀动作,当错过这个位置,定位器就按正常输出,所以出现震荡; 4.定位器电路板接线柱松脱,管线或调节阀震荡时,突然间断电,瞬间又恢复; 5.还有一种通常出现在刚更换过填料的调节阀,盘根比较紧,造成调节阀小信号不动作,等调节阀动作,已经超出所给信号,阀位震荡一次,才能回到给ABB阀门定位器,引起调节阀震荡。 以上就是ABB阀门定位器会引起调节阀震荡的原因,希望大家在使用的时候能够多加注意。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/ABBdwq/94.htmlPARent;">ABSolute;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%2C8%3A32768%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=1594280775672&bpp=13&bdt=486&idt=138&shv=r20200624&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=4770015213931&frm=23&ife=1&pv=2&ga_vid=1942863281.1594280776&ga_sid=1594280776&ga_hid=60410805&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=4&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=1203&bih=586&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066167&oid=3&pvsid=153395824537859&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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=0.7ddjwqasdomp&fsb=1&dtd=228" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.7ddjwqasdomp" data-load-complete="true"> |
