关键字:西门子定位器 http://www.siemens-positioner.com/ 西门子定位器采用微处理器对给位置和定值作比较。如果微处理器检测到偏差,它就用一个五步开关程序来控制压电阀,压电阀进而调节进入执行机构气室的气流量。 西门子定位器可用于控制角行程执行或气动直行程机构,使其在生活中广泛应用,主要用于以下行业:如制药和食品;污水和水;化工石化、电厂;玻璃和造纸等领域。 西门子定位器采用微处理器对给位置和定值作比较。如果微处理器检测到偏差,它就用一个五步开关程序来控制压电阀,压电阀进而调节进入执行机构气室的气流量。具体的五步为: 1、确定西门子定位器的正反作用 2、确定西门子定位器的零点和量程 3、确定阀门的开关时间 4、确定最小的定位增量 5、根据执行机构实际情况优化瞬态响应德科蒙过程控制(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.siemens-positioner.com/a/xwrd/271.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms 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?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1606378652307&bpp=9&bdt=70&idt=426&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=7830511255306&frm=23&ife=1&pv=1&ga_vid=632579569.1606378653&ga_sid=1606378653&ga_hid=18889204&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=9&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=85&eid=21068084&oid=3&pvsid=2054654472000094&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=8204&bc=31&ifi=0&uci=0.7wq5i6d2fx1x&fsb=1&dtd=468" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.7wq5i6d2fx1x" data-load-complete="true"> |
