艾默生流量计无故障、安全启动并投入运行,必须进行以下各项的预先检查:在正式启动流量计之前,一定要处理好每一个泄漏点;检查接线端子板上的供电电压及相应的正负极性;检查接到RS485转换器的频率输出引线的极性;检查气体涡轮流量计、温度/压力变送器显示是否正确、可靠,包括流量计的安装方向、垂直度所有连接部位的密封性能;其安装后的使用也是有一定的原则。如新安装或修理后的管路必须进行吹扫。吹扫计量管路时,必须拆下流量计,用相应短节代替流量计进行吹扫。管路投产时,应缓慢升压,逐步增加流速。停产时,应缓慢降压。运行中检查流量计运转的声音或壳体振动来判断涡轮叶片及轴承是否工作正常。低流速下应关注其声音变化情况,高流速下观察其壳体振动的变化。气体涡轮流量计加油方法:用手向下压油泵的手动杆直到停止,这样每次可以形成同样的油压。向下压动手动杆一次意味着油泵活塞的一个冲程。另外第一次使用时,需要使油泵到轴承之间的油路充满润滑。艾默生流量计开关操作步骤:打开旁路截止阀,先打开流量计上游截止阀,再缓慢打开流量计下游截止阀,关闭时应缓慢关闭旁路截止阀,先关闭流量计下游截止阀,再关闭流量计上游截止阀。武汉德科蒙过程控制有限公司027-88062221传真:027-88068180网址:http://www.whdkm.com/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%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=28.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1604976601452&bpp=14&bdt=223&idt=230&shv=r20201104&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=4473023838375&frm=23&ife=1&pv=1&ga_vid=1005316067.1604976602&ga_sid=1604976602&ga_hid=816002627&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=4&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=13&u_nmime=29&adx=-12245933&ady=-12245933&biw=1338&bih=689&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44726948%2C21067213&oid=3&pvsid=1388287963890420&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&brdim=457%2C164%2C457%2C164%2C1920%2C0%2C1359%2C689%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=29&ifi=0&uci=0.ntj65cbywrtf&dtd=253" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.ntj65cbywrtf" data-load-complete="true"> |
