阀门定位器外壳漏气问题需要引起重视

阀门定位器在使用的时候,有时会出现阀波动,影响定位器的使用,这可能是由于外壳漏气所导致的。

阀门定位器的放大器为一种力平衡式气动功率放大器,拆开检查问题出在背压室膜片上,该膜片为橡胶膜片,膜片有一边缘处较凹陷进去,装配时未能压好而漏气,所以每当输入电流信号变化,即背压变化时,调节阀就会波动。出现上述情况的时候,我们马上用限位螺杆将阀位顶至工艺要求的开度。检查输入电信号,接线是否出现问题,若均无问题,再检查定位器电气转换部分是否有输出,由于定位器排气孔一直放气,定位器无输出,判定气动功率放大器有故障。用同一型号的旧定位器上的气动功率放大气替换后,定位放大器有输出了。经在线调校,该阀恢复正常,且不再波动了。阀门定位器的非正常漏气的问题需要引起重视,气源气压不可随意提高。日常维护巡检时候,要查看气动功率放大器是否有漏气,这是就一定要用手去触摸一下,如有漏气应即时跟技术人员取得联系更换掉。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.azbil-china.com/a/xwzx/318.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%2C9%3A32776%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=1605250996297&bpp=19&bdt=72&idt=1357&shv=r20201111&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=3234831414970&frm=23&ife=1&pv=2&ga_vid=1577027988.1605250998&ga_sid=1605250998&ga_hid=1236775851&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=5&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=1203&bih=586&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21068737&oid=3&pvsid=3024893705040949&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%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=0.5keuugpws2yn&fsb=1&dtd=1407" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.5keuugpws2yn" data-load-complete="true">
