style="text-indent:25px">應(yīng)反復(fù)酸洗封頭幾次方能去除。尤其是復(fù)合板封頭在酸洗過程中，應(yīng)采用有效的保護(hù)措施，防止碳鋼層被腐蝕。酸洗完畢后，要讓其快速風(fēng)干，且內(nèi)部不得有剩余酸液。在封頭類產(chǎn)品制造過程中，必須要嚴(yán)格控制其的生產(chǎn)工藝。其中在下料環(huán)節(jié)，需要在保證產(chǎn)品質(zhì)量的情況下，盡可能節(jié)省材料。比如在1700毫米的封頭下料尺寸為φ2050毫米；通常下料的板材的標(biāo)準(zhǔn)寬度只有1500,2000,2200毫米等。這種情況下我們通常是選用寬度1500毫米的板材進(jìn)行下料。同時(shí)為了保證其的寬度，因而需要下兩塊料。浙江提取設(shè)備封頭加工球形封頭適合的介質(zhì)包括蒸汽、液體和氣體。</p><div

style="text-indent:25px">影響封頭較小厚度的因素有哪些？1、剛度的影響：封頭在承受壓力的同時(shí)本身應(yīng)具備一定的剛度，以免發(fā)生變形破壞。因此，GB150規(guī)定，對(duì)碳素鋼、低合金鋼制容器不包括腐蝕裕量的較小厚度應(yīng)不小于3mm；對(duì)高合金鋼制容器不包括腐蝕裕量的較小厚度不小于2mm。2、壓力載荷的影響：封頭是承受一定壓力的受壓元件，首先必須滿足的條件是壓力載荷，無論承受內(nèi)壓或者外壓載荷的封頭都可通過GB150第3章有關(guān)計(jì)算公式得到封頭計(jì)算厚度，其中，計(jì)算厚度+腐蝕裕量=設(shè)計(jì)厚度，這個(gè)設(shè)計(jì)厚度是單從壓力載荷方面得到的封頭需要的較小厚度。3、內(nèi)壓失穩(wěn)的影響：內(nèi)壓作用下，標(biāo)準(zhǔn)橢圓封頭的應(yīng)力分布如圖1。由應(yīng)力分布圖可以看出，在封頭底邊處產(chǎn)生周向壓縮應(yīng)力，此處封頭容易發(fā)生周向失穩(wěn)。為防止橢圓封頭在內(nèi)壓作用下失穩(wěn)，GB150規(guī)定，對(duì)于Di/2hi≤2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.15%，對(duì)于Di/2hi＞2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.30%。上述雖然限制的是有效厚度，但其實(shí)也間接限制了封頭成形的較小厚度。封頭由于填料的塑性，會(huì)產(chǎn)生徑向力，而且會(huì)同閥桿之間緊密接觸。</p><div

style="text-indent:25px">標(biāo)準(zhǔn)橢圓封頭作為壓力容器中比較重要的受壓元件之一，在選用的時(shí)候，我們通常是根據(jù)需要的標(biāo)準(zhǔn)進(jìn)行選擇，但很多時(shí)候有些工作人員在標(biāo)準(zhǔn)橢圓封頭加工困難的情況下，采用旋壓橢圓封頭進(jìn)行替代，這種做法是不可取的。一方面是因?yàn)闃?biāo)準(zhǔn)橢圓封頭與旋壓橢圓封頭在制造的方法上是不同的，因此使用時(shí)不能進(jìn)行有效替代。標(biāo)準(zhǔn)橢圓封頭的形狀是由沖壓模具來決定的，因此只要將所中的沖壓模具按照標(biāo)準(zhǔn)的橢圓封頭形狀進(jìn)行加工可以了，所沖壓封頭是標(biāo)準(zhǔn)的橢圓封頭。封頭在工作時(shí)可以保證調(diào)節(jié)閥的正確定位。浙江提取設(shè)備封頭加工</p><p

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。浙江提取設(shè)備封頭加工</p><p
