style="text-indent:25px">在封頭種類里面，有這樣一類封頭，它的任意尺寸都可以定做，無論是否有模具，都能生產(chǎn)出來，這種封頭，就是我們常說的無直邊封頭，也叫球冠形封頭，還有一種叫法是太陽(yáng)盤封頭。無直邊封頭：其形狀就是一個(gè)圓弧底，沒有直邊，像一個(gè)鍋底一樣。這種封頭結(jié)構(gòu)非常簡(jiǎn)單，因?yàn)槿我獬叽缍伎梢远ㄗ?，局限性小，所以在比較多非標(biāo)設(shè)備中也常常受到客戶青睞。但是在定做這種封頭時(shí)，高度以及弧度非常重要，因?yàn)闆]有標(biāo)準(zhǔn)的模具，所以在成型之后，會(huì)有較大的誤差。正所謂，有利就有弊，雖然任何尺寸都可以做，但是當(dāng)無直邊封頭焊接時(shí)，因?yàn)闆]有直邊，所以操作起來沒有其它形狀的封頭方便，因此，在對(duì)焊之時(shí)一定要非常注意操作，較好是選擇讓技術(shù)熟練的焊接工人進(jìn)行處理。</p><p style="text-indent:25px">新型大型封頭的生產(chǎn)制造流程視乎比較簡(jiǎn)單，可是對(duì)于一個(gè)新型大型封頭公司來講機(jī)器的設(shè)備是要求比較高的，一些大型的機(jī)器貴的數(shù)百萬，液壓設(shè)備都要用比較好點(diǎn)的，還沒有保修和維護(hù)的保障。另外還有一個(gè)就是新型大型封頭的模具，一些口徑達(dá)到幾米的新型大型封頭模具成本是比較高的，如果后期生產(chǎn)的量上不來的話，這個(gè)成本是不劃算的。首先是根據(jù)客戶下單的需求去采購(gòu)?fù)瑯硬馁|(zhì)的鋼板，鋼板的大小長(zhǎng)度以及厚度尺寸也要把握好；其次是下料，也是要根據(jù)新型大型封頭的口徑大小來切割鋼板的面積；是要使用模具和鍛壓設(shè)備讓鋼板變成新型大型封頭，這一關(guān)也是技術(shù)含量比較高的環(huán)節(jié)；后面的就是一些清洗和修飾工作了，全部弄好以后就是運(yùn)載上車發(fā)貨，有一些要求稍微高一點(diǎn)的，還會(huì)要求生產(chǎn)廠家提供新型大型封頭的材質(zhì)檢測(cè)單，確定材質(zhì)無誤，以免影響客戶的使用。我們大多數(shù)使用不銹鋼封頭，都是要求能夠比較長(zhǎng)時(shí)間的將建筑物的外貌能夠長(zhǎng)期進(jìn)行保持。</p><div

style="text-indent:25px">球形封頭的性能與特點(diǎn)分析：1、從受力情況看：球形封頭的兩向應(yīng)力相等，而且在相同的P和D條件下，球形封頭上的應(yīng)力*為筒體上的周向應(yīng)力的一半；橢圓形封頭經(jīng)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，對(duì)于標(biāo)準(zhǔn)橢圓形封頭ab2，在相同的P和D條件下，封頭較大的薄膜應(yīng)力數(shù)值上與圓筒中的周向應(yīng)力相等。故橢圓形封頭的受力狀況*次于半球形封頭，而比其它封頭好；2、從制造難易程度看：橢圓形封頭的深度比半球形封頭淺的多，較易制造；3、從制造所使用的材料多少來看：從理論上講，在一些條件均相同之下，標(biāo)準(zhǔn)橢圓形封頭壁厚大約比半球形封頭厚一倍，而與圓筒的壁厚相近。故球形封頭比橢圓形封頭更節(jié)約材料。4、從結(jié)構(gòu)上看：球形封頭為半個(gè)球殼。5、球形封頭因具有受力均勻、應(yīng)力較小的等優(yōu)點(diǎn)被普遍用于壓力較高、直徑較大的高壓容器和特殊需要的場(chǎng)合；橢圓形封頭經(jīng)線曲率變化平滑連續(xù)，易于沖壓成型，是目前應(yīng)用較多的封頭。封頭就是起到一個(gè)封死管道的作用。南京原水處理設(shè)備封頭廠</p><p

style="text-indent:25px">壓力封頭有什么特點(diǎn)你知道嗎？其一、使用上有優(yōu)良的硬度，要知道我們使用上較關(guān)鍵的就是硬度問題，這種硬度使用上也是我們較關(guān)注的問題，因?yàn)檫@種硬度上一方面也反映了整體的承壓能力，雖然承壓能力上有比較多方面，就連封頭材料的彈性都可以算作其中的因素之一。硬度雖然有一定影響，但是不是主要影響，所以這方面一定要注意，不能只看硬度。不過話說回來，硬度上也會(huì)影響比較多方面的影響維持設(shè)備壓力的穩(wěn)定性能，所以也不能不看硬度。其二、封頭本身有著良好的屋里結(jié)構(gòu)，使用上比較多半圓形的封頭抗壓能力上也會(huì)更好一些，承受壓力能力也會(huì)好比較多，這點(diǎn)上上也是為什么封頭使用上物理性能和結(jié)構(gòu)非常優(yōu)良的原因所在。加上市場(chǎng)對(duì)封頭的需求上是剛需，雖然處于低迷期，不過后續(xù)需求增大，封頭的市場(chǎng)也會(huì)成為朝陽(yáng)，而且封頭的質(zhì)量上也會(huì)有明顯的提升。催化劑罐封頭制造廠</p><p
