关键字：阀门定位器 http://www.samson-china.com/ 电动阀门定位器也就是我们常见的气动阀门定位器，通常与气动调节阀配套使用，它接受调节器的输出信号，然后以它的输出信号去控制气动调节阀，当调节阀动作后，阀杆的位移又通过机械装置反馈到阀门定位器，阀位状况通过电信号传给上位系统。最近我们又总结了该类阀门定位器在使用过程中会遇到的问题。1.气动阀门定位器的测量精度不好：故障原因解决方案喷嘴、档板调整不好重新调整平行度或喷嘴固定螺钉，满足精度要求闸阀背压气路漏消除漏气现象调零螺钉调整不当重新调整调零螺钉满足精度要求反馈杠杆与固定销钉位置不对重新按行程要求调整销钉位置调节阀径向位移大检修调节阀2.电动阀门定位器无输入时还有输出：这个故障主要由于两方面因素，第一个是由于阀门定位器的背压部分堵塞，我们只需清除堵塞污物即可。第二个缘故是由于自动与手动切换开关位置不当，将“自动与手动切换开关按顺时针方向旋转到“自动”止回阀位置。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.samson-china.com/a/xwzx/262.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&adsid=NT&dt=1597996756756&bpp=6&bdt=632&idt=212&shv=r20200817&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=4564411169545&frm=23&ife=1&pv=1&ga_vid=272455215.1597996757&ga_sid=1597996757&ga_hid=668977257&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=4&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=1286&bih=626&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21067034%2C21067104&oid=3&pvsid=1395339980379339&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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.redb68z311h9&fsb=1&dtd=241" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.redb68z311h9" data-load-complete="true"> |
