eja变送器和三阀组连接，首先把常规式阀组与变送器法兰对正。使用四个阀组螺栓进行定位。用手拧紧螺栓，然后按交叉模式逐渐把螺栓拧紧到最终扭矩值。按照变送器的Z高压力范围对组件进行泄漏检查。一体化阀组安装到eja差压变送器，需要检查 PTFE 传感器模块 O 形圈。完好的 O 形圈可以重用。如果 O 形圈损坏 （例如有裂纹或切口），应把其更换为针对罗斯蒙特变送器设计的新 O 形圈。重要提示如果更换 O 形圈，在拆卸损坏的 O 形圈时，注意不要划伤或损伤 O 形圈的凹槽或隔膜的表面。在传感器模块上安装一体化阀组。使用四个2.25 英寸阀组螺栓进行定位，用手拧紧螺栓，然后按交叉模式逐渐把螺栓拧紧到Z终扭矩值。如果更换了 PTFE 传感器模块 O 形圈，那么在安装后应重新拧紧法兰螺栓，以补偿O 形圈的冷变形。http://www.wuhandekema.com/武汉德科蒙过程控制有限公司027-88062221传真：027-88068180。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" 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=28.0.0&pra=5&wgl=1&dt=1610096102327&bpp=14&bdt=79&idt=152&shv=r20201203&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=5556471064479&frm=23&ife=1&pv=2&ga_vid=1670521600.1610096103&ga_sid=1610096103&ga_hid=94450701&ga_fc=0&nhd=1&u_tz=480&u_his=6&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=11&u_nmime=26&adx=-12245933&ady=-12245933&biw=1318&bih=828&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21068769&oid=3&pvsid=4271604499517819&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=529%2C139%2C529%2C139%2C1920%2C0%2C1318%2C828%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=29&ifi=0&uci=0.31jqmkoo4xpg&dtd=186" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.31jqmkoo4xpg" data-load-complete="true"> |
