关键字:阀门定位器 http://www.azbil-china.com/ 智能阀门定位器将会是今后控制阀,提高控制系统性能的主要设备。这是因为它有以下几个特点:1.消除串级共振:阀门定位器在副环中,可调整前向通道放大器,或在主环中,可改变非线性补偿环节的增益,使主副被控对象的时间常数错开,消除串级控制系统的共振。 2.消除副环非线性特性:非线性补偿环节设置在前向通道,不设置在反馈通道,反馈通道采用线性环节,不采用非线性的凸轮,从而保证副环主要用于克服阀杆的死区、摩擦等扰动影响,阀门定位器分发挥串级副环回路能有效克服进入副环扰动的优点。 3.非线性补偿范围扩大:非线性补偿环节设置在前向通道后,阀门定位器可有效地补偿被控过程的非线性,补偿范围可根据被控过程由人工设定。 以上就是智能阀门定位器的一些特点,希望这些能够在大家使用阀门定位器有所帮助。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.azbil-china.com/a/XWZX/281.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=1594366602704&bpp=11&bdt=80&idt=227&shv=r20200624&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=6439122253708&frm=23&ife=1&pv=2&ga_vid=866983196.1594366603&ga_sid=1594366603&ga_hid=839190167&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=5&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=21065532&oid=3&pvsid=2554628595082727&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%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.xq84816wd3k2&fsb=1&dtd=290" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.xq84816wd3k2" data-load-complete="true"> |
