阀门定位器线性及滞后度问题的解决

 关键字:阀门定位器      http://www.samson-china.com/

 阀门定位器在使用的过程中常常会出现一些小问题,今天我们给大家总结了一下两个问题,希望对大家的使用有所帮助。

  1.阀门定位器的线性不好:

  (1)确认阀门定位器安装位置是否正确。特别要确认输入信号50%时反馈杆是否保持水平。如果不水平,请重新安装定位器。

  (2)确认零点和量程设定是否正确。确认零点是否过低,量程是否过高。特别是零点设定不正确的话,量程也会不正确,因此首先要调好零点。

  (3)确认空气过滤减压阀的输出压力是否恒定。如果减压阀的输出压力有波动,请更换减压阀。   2.阀门定位器滞后度过大时。   (1)如果是双作用的执行机构,请确认底座调节旋钮设定是否正确。   (2)如果阀门定位器反馈杆上的固定弹簧过于松懈,会产生滞后现象。这时请调整反馈杆上的固定弹簧,消除反馈杆和阀杆连接棒的滞后间距。   (3)确认连接在执行机构推杆和阀杆连接件上的反馈连接棒是否松懈,如果松懈请重新固定。武汉)有限公司传真:027-88068180原文出处:http://www.samson-china.com/a/xwzx/268.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%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=1599637848463&bpp=6&bdt=69&idt=40&shv=r20200901&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=1678092510308&frm=23&ife=1&pv=2&ga_vid=2074626205.1599637849&ga_sid=1599637849&ga_hid=1952340451&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=13&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&eid=42530622%2C44726948%2C21066898&oid=3&pvsid=4227679062159600&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.k2thh2z95xfk&fsb=1&dtd=76" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.k2thh2z95xfk" data-load-complete="true">
