儀器儀表保(bao)溫(wen)和保(bao)護的作用
北京中儀(yi)宇盛科技有限公司
一(yi)般(ban)來說儀(yi)表管(guan)線(xian)內介質的(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)應該(gai)在20--80度(du)(du)之間(jian),儀(yi)表保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)箱(xiang)(xiang)內的(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)比(bi)較適宜保(bao)(bao)持(chi)在15--20度(du)(du)之間(jian)。為(wei)了補償(chang)儀(yi)表管(guan)線(xian)和容器(qi)以及儀(yi)表保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)箱(xiang)(xiang)所(suo)(suo)散(san)發和損失(shi)的(de)(de)熱(re)(re)(re)量(liang),需(xu)采(cai)取(qu)保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)伴(ban)(ban)熱(re)(re)(re)措施。目前(qian)主要(yao)為(wei)二種(zhong)保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)伴(ban)(ban)熱(re)(re)(re)措施,一(yi)種(zhong)為(wei)傳統的(de)(de)蒸(zheng)汽(qi)和熱(re)(re)(re)水(shui)伴(ban)(ban)熱(re)(re)(re)。另一(yi)種(zhong)為(wei)電(dian)伴(ban)(ban)熱(re)(re)(re)。近年來隨著電(dian)伴(ban)(ban)熱(re)(re)(re)技術(shu)的(de)(de)成熟(shu)并(bing)且(qie)所(suo)(suo)具(ju)有(you)的(de)(de)*優(you)點,將(jiang)逐步成為(wei)取(qu)代(dai)蒸(zheng)汽(qi)和熱(re)(re)(re)水(shui)伴(ban)(ban)熱(re)(re)(re)的(de)(de)新一(yi)代(dai)保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)方(fang)(fang)式。儀(yi)表保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)箱(xiang)(xiang)的(de)(de)蒸(zheng)汽(qi)伴(ban)(ban)熱(re)(re)(re)主要(yao)由箱(xiang)(xiang)體,內襯保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)材料,變送器(qi)支架,U形蒸(zheng)汽(qi)散(san)熱(re)(re)(re)器(qi)組(zu)成。為(wei)便(bian)于日常(chang)維護,在箱(xiang)(xiang)體的(de)(de)門上(shang)常(chang)設(she)有(you)觀察窗,箱(xiang)(xiang)頂(ding)可(ke)設(she)有(you)插入雙金屬測(ce)溫(wen)(wen)(wen)(wen)(wen)無件(jian)的(de)(de)開孔。儀(yi)表保(bao)(bao)溫(wen)(wen)(wen)(wen)(wen)箱(xiang)(xiang)的(de)(de)電(dian)伴(ban)(ban)熱(re)(re)(re)一(yi)般(ban)采(cai)用(yong)(yong)電(dian)熱(re)(re)(re)管(guan),而(er)儀(yi)表管(guan)線(xian)的(de)(de)電(dian)伴(ban)(ban)熱(re)(re)(re)采(cai)用(yong)(yong)的(de)(de)是電(dian)熱(re)(re)(re)帶(dai),電(dian)熱(re)(re)(re)管(guan)是以無縫鋼管(guan)為(wei)外殼,內裝電(dian)阻(zu)絲并(bing)充填氧化(hua)鎂粉絕(jue)緣,電(dian)伴(ban)(ban)熱(re)(re)(re)具(ju)有(you)熱(re)(re)(re)郊率高,節(jie)約能源(yuan),設(she)計簡(jian)單,施工安裝方(fang)(fang)便(bian),無污染,使(shi)用(yong)(yong)壽命長,能實現(xian)遙(yao)控(kong)和自動控(kong)制等優(you)點。是取(qu)代(dai)蒸(zheng)汽(qi)和熱(re)(re)(re)水(shui)伴(ban)(ban)熱(re)(re)(re)的(de)(de)技術(shu)發展(zhan)方(fang)(fang)向。目前(qian)已(yi)在各(ge)行業(ye)的(de)(de)工礦企業(ye)中有(you)廣泛(fan)的(de)(de)應用(yong)(yong)。
