横河变送器故障现象在催化剂生产过程中,需要测量浆液的压力和流量,虽然引压导管很短,但仪表使用一段时间后,常发现被堵塞,从而引起仪表输出变化缓慢,甚至不变。分析和措施在生产过程中,常遇到被测质内含有固体悬浮颗粒或粉末,时间久了引起压导管堵塞,使测量无法正常进行。在这种情况下,不能用通常的引压管仪表,而要用隔膜式压力表或远程法兰式变送器。横河变送器差常见的故障还有:变送器高压导管堵塞或泄漏;变送器高低压导管接反;工艺管道内的介质流动方向相反。一般情况下,输出能随差压信号的变化而变化,导压管也无堵塞和泄漏,而是高低压导压管接反(介质流向相反,也可看作导压管接反)。法兰膜盒面积大,较易清除被测介质,并能承受较高的温度。它除了用于测量含有悬浮颗粒的浆液、过于粘稠、易于冻结、固化、结晶的介质外,还常用于引|压管中的气体较易出现凝液,或液体介质中较易出现气化的场合,因为这些场合中的介质,若用普通仪表测量,则会使导管中的静压变化而引起仪表输出不稳。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?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%2C32%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=1618901327536&bpp=6&bdt=147&idt=144&shv=r20210415&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=3909158620879&frm=23&ife=1&pv=1&ga_vid=1851517921.1618901328&ga_sid=1618901328&ga_hid=1102160311&ga_fc=0&nhd=1&u_tz=480&u_his=7&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=1178&bih=801&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44736524%2C44740079&oid=3&pvsid=2817954904946371&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=665%2C139%2C665%2C139%2C1920%2C0%2C1178%2C801%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=29&ifi=1&uci=1.ch5sagaylw69&dtd=170" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.ch5sagaylw69" data-load-complete="true"> |
