style="text-indent:25px">如何防止球形封頭變形？球形封頭中，根據(jù)壓機(jī)立柱間距和壓模尺寸及鋼板尺寸，選定頂圓需拼焊的板寬和拼焊塊數(shù)。盡可能采用壓鼓。直徑7.5m球形封頂圓取直徑6.2m，3塊板拼焊后壓鼓，然后車環(huán)縫坡口；直徑6.5m球形封頭頂圓取直徑5.36m，2塊板拼焊后壓鼓，然后車環(huán)縫坡口。直徑12m球形封頭頂圓取直徑lOm，直徑較大，由5塊板拼接，先分別壓形，然后切割研配向心、徑向縱縫坡口。為了防止自由變形，先制2個(gè)圓胎，檢測(cè)研配都可在此胎上進(jìn)行。球形封頭是以球殼的球冠部分所形成的封頭，有半球形封頭和無(wú)折邊球性封頭兩類。它在同樣容積下表面積較小，相同承壓條件下需要的厚度較薄，從節(jié)省材料和強(qiáng)度上看，是較合理的。另外，球形封頭具有鍛打精良，表面光滑，耐酸耐堿耐高溫，外形美觀，質(zhì)感性能強(qiáng)等特點(diǎn)。此類封頭為一塊深度比較淺的球面體(球冠)。其結(jié)構(gòu)見(jiàn)圖。它結(jié)構(gòu)簡(jiǎn)單，深度淺，易加_百一制造，成本低。但它與筒體連接處存在著明顯的形狀突變，導(dǎo)致產(chǎn)生比較高的局部應(yīng)力，故受力狀況極差，所以這類封頭一般只能用于直徑比較小，壓力較低的容器。連云港鋁封頭生產(chǎn)廠家直銷維護(hù)好封頭才是硬道理。</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(lái)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。封頭的品質(zhì)直接關(guān)系到壓力容器的長(zhǎng)期安全可靠運(yùn)行。</p><div
