SIEMENS定位器如何准确控制精度

关键字：SIEMENS定位器      http://www.siemens-positioner.com/

SIEMENS定位器在调节阀检修之后，发现控制精度有问题，面对这个问题我们可以有以下的解决方案。

SIEMENS定位器调节阀检修后，由于定位器、阀杆和反馈部分可能的变动，必须经过初始化后，定位器才能和执行机构相互配合,根据所接收到的控制信号，驱动执行机构按要求动作。西门子SIPART PS2阀门定位器的自动初始化过程由五步组成，每一步均完成相应的工作任务，具体步骤如下： 1.确定SIEMENS定位器是正作用还是反作用，LCD显示为RUN1； 2.确定SIEMENS定位器的起始点和量程范围,LCD显示为RUN2； 3.确定执行机构的定位时间，LCD显示为RUN3； 4.确定阀门的定位增量值，LCD显示为RUN4； 5.优化执行机构动态响应，LCD显示为RUN5。 以上五个步骤完成后，SIEMENS定位器的LCD显示Finish,完成自动初始化过程，定位器才能正常工作。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/202.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%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&dt=1590739198854&bpp=10&bdt=239&idt=173&shv=r20200526&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=1460360331096&frm=23&ife=1&pv=1&ga_vid=1183275270.1590739199&ga_sid=1590739199&ga_hid=442635019&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=1381&bih=673&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066085&oid=3&pvsid=1612601806272645&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.pdq3fdnhmo4x&fsb=1&dtd=198" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.pdq3fdnhmo4x" data-load-complete="true">
