粉煤雷达物位计环腔进水故障的维修

 关键字：雷达物位计    http://www.dkmcn.com/​

粉煤雷达物位计主要由燃烧室、激冷室、壳体、螺旋盘管式水冷壁和激冷室内件等组成。水冷壁主要由燃烧室主盘管、渣口盘管和炉盖盘管三部分组成。今天我们主要介绍如何检查和维修该类雷达物位计的环腔。

在检查维修之前我们需要认识粉煤雷达物位计环腔内主要有主盘管进出水空间管、炉壳接管、环腔保护气管、主盘管定位管、测温传感器导线等。该类雷达物位计目前常见的安全隐患主要是环腔保护气携带细灰磨损主盘管进出水空间管及炉壳接管，导致管材泄漏，雷达物位计环腔进水，所以需要我们重点检查环腔积灰情况及保护气系统。除了上述原因进水以外，粉煤雷达物位计在运行及停车期间可能出现环腔泄漏进水的原因有以下几个：雷达物位计插入式及埋入式传感器大范围显示异常或显示坏值；物位计环腔温度传感器显示温度较正常值偏高；汽包净补水量增大。出现这种情况，我们的主要检查方法是打开粉煤雷达物位计预留孔或清灰孔，发现管口有水流出则判断粉煤雷达物位计环腔泄漏。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.dkmcn.com/News_show.asp?id=859PARent;">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=1594886785612&bpp=4&bdt=62&idt=457&shv=r20200713&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=5090576719771&frm=23&ife=1&pv=1&ga_vid=294328308.1594886786&ga_sid=1594886786&ga_hid=1912186406&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&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=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=3734062842240347&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%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=8220&bc=31&ifi=0&uci=0.f59y9jyc3dal&fsb=1&dtd=489" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.f59y9jyc3dal" data-load-complete="true">
