href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>電熱管</strong></font></a>時，溝通時被問用在哪里，是單頭電熱管還是雙頭電熱管，客戶分不清楚，只知道是直棒型的，通過加微信發(fā)來圖片才知道是哪種，但是在這玲瑯滿目的電加熱產(chǎn)品中，根據(jù)<a href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>電加熱管</strong></font></a>結(jié)構(gòu)卻只有兩類，一是單頭電熱管，二是雙頭電熱管。下面和大家分享下單頭電熱管和雙頭電加熱管的共同點和區(qū)別。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">一、定義：</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">管狀電熱元件在制造時是按直管生產(chǎn)的，通過縮管、退火、彎管等工序加工而成。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（1）單頭電熱管顧名思義即尾部封死，止在另一端出引線或接線柱；如擠壓筒電加熱管就是帶限位擋片的單頭電熱管。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（2）雙頭電加熱管則是在直管的兩端分別出引線或接線柱；如常用于烤漆房的雙頭空氣干燒電熱管。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;"></span></p><p style="text-align: center"><img src="/data/upload/image/20190115/1547540858439591.jpg" title="單頭加熱管" alt="單頭加熱管" width="600" height="401" border="0" vspace="0" style="width: 600px; height: 401px;"/></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">二、單頭加熱管和雙頭加熱管的共同點和區(qū)別<br/></span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">A、兩者的共同點</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（1）單頭電加熱管和雙頭電加熱管的管子表面都是不帶電的；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（2）都具有結(jié)構(gòu)簡單，機械強度高、熱效率高、安全可靠、安裝簡便、使用壽命長的特點；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（3）都可用于固體、液體、氣體介質(zhì)加熱。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">B、兩者的區(qū)別</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（1）結(jié)構(gòu)上，內(nèi)部電阻絲排布方式是不一樣的；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（2）使用環(huán)境上，單頭電熱管適合在不能進行兩端接線的加熱環(huán)境中工作；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（3）表面負荷設(shè)計上，單頭表面負荷：1-22w/cm2，雙頭表面負荷：1-8w/cm2；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（4）升溫速度上，單頭電熱管體積小、功率大所以升溫迅速，幾十秒甚至幾秒能瞬間到3～4百度。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（5）功率設(shè)計不同：同樣的管徑和長度，單頭電熱管的功率要比雙頭電熱管的大。例如：管徑12mm 管長250mm 的單頭管在干燒的情況下，功率最大可以做700W,而在同樣的使用環(huán)境下雙頭加熱管最大只能做375W.</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">(6)結(jié)構(gòu)不同：兩根引線是從加熱棒的一端引出，雙頭加熱管的兩根引線是分別從電熱管的兩端引出來的。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">所以在知道了單頭電熱管與雙頭電熱管的區(qū)別以后，我們就能很好的區(qū)分我們看到的電熱管是單頭加熱管還是雙頭加熱管。像U型加熱管，W型的，都是屬于雙頭加熱管。而形狀復(fù)雜的其實也屬于雙頭管的范疇，因為它是由1根、2根、3根或者3的倍數(shù)根的U型管組成的?，F(xiàn)在你會根據(jù)電加熱管結(jié)構(gòu)來區(qū)分單頭加熱管和雙頭加熱管了吧!</span></p></div>
