防爆電(dian)伴(ban)熱帶(dai)-天(tian)津旭誠-防爆電(dian)伴(ban)熱帶(dai)價格

　　按(an)電(dian)(dian)伴熱(re)各路(lu)的電(dian)(dian)壓、電(dian)(dian)流等參數選(xuan)定雙極(ji)性(xing)斷電(dian)(dian)和(he)漏電(dian)(dian)保護斷路(lu)器(qi)，凡(fan)需蒸(zheng)汽清掃管線(xian)除垢時(shi)，應(ying)注(zhu)意先清掃后安(an)裝電(dian)(dian)熱(re)帶(dai)，如(ru)需每年例行(xing)掃線(xian)檢修應(ying)按(an)特殊情況(kuang)設計(ji)安(an)裝。

　　關鍵點提示：

　　1、電伴熱帶的安裝調(diao)試和(he)運行(xing)必須遵循國家頒布的GB50254-96《和(he)火災危(wei)險(xian)環境電氣裝置施工(gong)(gong)及驗(yan)收規(gui)范》和(he)GB50257—96《低壓電器施工(gong)(gong)及驗(yan)收規(gui)范》等有關條(tiao)文。

　　2、各種電(dian)伴(ban)熱帶安裝敷設時均有彎曲(qu)半徑要求，如(ru)果過度(du)彎曲(qu)將(jiang)會(hui)損壞電(dian)伴(ban)熱帶。

　　3、沿管道(dao)平(ping)行敷設(she)的電(dian)伴熱帶一般安(an)裝在管道(dao)下(xia)方，且(qie)與管道(dao)橫截面的水平(ping)軸線呈(cheng)45。角，若用2根(gen)電(dian)伴熱帶要(yao)對稱敷設(she)。

　　4、在容器(qi)上(shang)安(an)裝時，電伴熱帶應纏繞(rao)在容器(qi)中下部，通(tong)常不超過容器(qi)高度的2/3，一般為l/3。

　　5、非金屬管道的電(dian)伴熱(re)(re)，應(ying)在管外壁與電(dian)伴熱(re)(re)帶之(zhi)間夾一金屬片(鋁(lv)箔)，以提高伴熱(re)(re)效果。

　　6、安裝(zhuang)電(dian)伴熱(re)帶要充(chong)分(fen)考慮管道附件和設備拆(chai)卸的可能性(xing)，確保電(dian)伴熱(re)帶本身(shen)不損壞。

　　7、安裝附(fu)件時，要求膠圈(quan)、墊圈(quan)、緊(jin)固件等(deng)齊(qi)全，安裝正確、緊(jin)固，以防松動(dong)或盒內進水(shui)。
