style="text-indent:25px">為什么多數(shù)采用標(biāo)準(zhǔn)橢圓形封頭呢？這是因為其的加工比較復(fù)雜，成本較高。到目前為止，在很多的工業(yè)領(lǐng)域中都會使用到封頭產(chǎn)品，其作為一個重要的部件，究竟起到了什么樣的作用呢？我們可以將封頭看作是壓力容器上的端蓋，是壓力容器的一個主要承壓部件，其所起的作用是密封作用。封頭類產(chǎn)品加工生產(chǎn)中，其中有一道工序叫做酸洗。之所以要進行酸洗，主要是希望通過這一到工序來將成型封頭表面的焊渣、熔渣、油污及氧化皮等污物清洗干凈。常州SS油罐封頭廠家封頭建立了閥桿位移量與控制器輸出信號之間的一一對應(yīng)關(guān)系。</p><div
