关键字:西门子定位器 http://www.siemens-positioner.com/ 西门子定位器与其他定位相比,可以实现行程检测模块和控制器可分离安装。原常规一体式定位器安装在阀体上,随阀门一起振动,极易造成定位器内部元器件松动及损坏,从而产生误动作导致机组跳车,影响生产。下面我们一起来看看怎么处理这个问题。 1.西门子定位器更换气源管采用不锈钢金属编织PTFE内衬挠性软管代替不锈钢气源硬管,防止了阀体振动传递到分离安装的电路单元。 2.更换定位器采用行程检测模块与控制器电路单元分开安装,代替只能安装在控制阀上的一体式定位器。西门子定位器只有阀杆行程检测模块安装在阀体上的阀杆连接处、电路较多的主定位器单元从阀门上分离,单独固定安装,不再安装在阀门本体上。 3.更改气动放大器(即流体增压器)安装位置,气动放大器垂直安装改为水平安装。有的品牌的放大器内部阀杆较细,垂直安装受振动影响更大。由于防喘振控制特点要求防喘振阀快开慢关,因此在气路上还需配以气动放大器(即流体增压器)实现快开、(单向)阻尼器(即节流调节阀)实现慢关功能,与西门子定位器装配后,重新联调很重要。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地址:武汉市武昌区中南国际城D座一单元901室原文出处:http://www.siemens-positioner.com/a/XWRD/199.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%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&adsid=NT&dt=1590480032051&bpp=9&bdt=70&idt=295&shv=r20200519&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=1576769778721&frm=23&ife=1&pv=2&ga_vid=1299455709.1590480032&ga_sid=1590480032&ga_hid=172429677&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=16&u_nmime=33&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066085&oid=3&pvsid=920245993223494&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.vku9j7aw3dz9&fsb=1&dtd=337" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.vku9j7aw3dz9" data-load-complete="true"> |
