font-size: 16px;">電加熱器怎么安裝 </span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;"><a href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>電熱管</strong></font></a>的安裝非常重要，它的作用大小好比人的心臟一樣，要想讓這個(gè)心臟長(zhǎng)久的運(yùn)轉(zhuǎn)工作，我們須要正確的來(lái)了解它，防止操作的失誤而讓它損壞。所以我們一直認(rèn)為電熱管的安裝需要遵循一定的步驟，按照正確的操作步驟讓電熱管長(zhǎng)久的工作下去。如何做呢？</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;"><a href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>電加熱管</strong></font></a>廠家為大家講解一下電熱管安裝的基本要求</span><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">：</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">1、保證爐膛溫度分布均勻。在以輻射傳熱為主的大型中溫爐和高溫爐爐膛中，除了在爐墻和爐底上安裝元件外，也可以在爐頂和爐門(mén)上也安裝電熱管。同時(shí)，在爐子熱損失大的地方、爐門(mén)孔附近，振底爐出料口附近，應(yīng)多安裝一些電熱管。當(dāng)爐膛高度很矮時(shí)，電熱管往往布置在爐底和爐頂上。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">2、絲狀電熱管的波紋式、螺旋式及帶狀電熱管的波紋式三種安裝去法，從使用壽命來(lái)說(shuō)，以絲狀波紋式較好，帶狀波紋式次之，而絲狀螺旋式較差。波紋式絲狀電熱管，其換熱條件比較好，即使表面負(fù)荷選大一些，使用壽命也較長(zhǎng)，因而可節(jié)省電熱管材料和維修工時(shí)。</span></p><p style="line-height: 2em; text-align: center; text-indent: 0em;"><img src="/data/upload/image/20190117/1547706403475585.jpg" alt="高溫電加熱管" width="600" height="400" border="0" vspace="0" title="高溫電加熱管" style="width: 600px;

16px;">3、要盡量減少電熱管之間及其與爐壁支持磚之間的輻射屏蔽。電熱管安裝位置，應(yīng)使熱量容易傳給工件，而又不使工件局部過(guò)熱。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">4、中溫爐電熱管的支撐應(yīng)選高鋁質(zhì)制品，爐溫在1000℃以上的髙溫爐應(yīng)采用較純的氧化鋁制品，低溫爐可采用一般黏土質(zhì)制品。耐火制品中的氧化鐵含量要小，石棉、礦渣棉、水玻璃等不能與電熱管接觸。因這些與電熱管生成易熔共晶，使元件燒斷，還可破壞電熱管的氧化膜層，使電熱管加速氧化而損壞。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="color: rgb(0, 0, 0); font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">工業(yè)電熱管在設(shè)備中的安裝可能還遠(yuǎn)遠(yuǎn)不止這些，電熱管如何能更好的長(zhǎng)久工作，我們?cè)敢夤餐奶剿?。這樣不但能促進(jìn)我們生產(chǎn)者的改善而且更能提高產(chǎn)品的質(zhì)量。</span></p></div> <h3 class="tag">本文網(wǎng)址：http:///news/522.html
