关键字：阀门定位器 http://www.samson-china.com/ 阀门定位器在测量的过程中，气源是比较重要的一个环节。气源一般是专用的仪表气源或是压缩空气，有时可以用氮气代用。可以接收来自控制设备的DC电流信号并控制气动阀门，还具有通信功能、自动设定程序以及自诊断功能，极大地提高了生产力和效率。 由于自然的天气变化，夏季气温高是气体含水达到饱和，进入冬季温度降低结露有大量水析出，造成调节阀堵塞，结冻，不能正常工作。解决办法是在最低点把水排出，或是用蒸汽化冻排水，根本解决办法是气源总管加装过滤器。 智能阀门定位器可以接受手操器的输出18毫安电流，进行智能调整排除故障，具体操作是阀门定位器在输入18毫安电流时，用螺丝刀顺时针拧90度，三秒钟，阀杆反复两次，松开螺丝刀。阀位停在50%处保持三分钟，整定完成，正常校验。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.samson-china.com/a/xwzx/224.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%3A32776%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=29.0.0&pra=5&wgl=1&dt=1589355988714&bpp=8&bdt=48&idt=232&shv=r20200506&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=4038553941025&frm=23&ife=1&pv=1&ga_vid=1004588137.1589355989&ga_sid=1589355989&ga_hid=586457772&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=1&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=502003421501339&pem=851&ref=https%3A%2F%2Fblog.bizrobot.com%2Fblog_company_241417.htm&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=0.6pgiuhzhk5cz&fsb=1&dtd=256" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.6pgiuhzhk5cz" data-load-complete="true"> |
