管殼式換熱器是把換熱管束與管板連接后，再用筒體與管箱包起來，形成兩個獨立的空間。管內的通道及與其相貫通的管箱稱為管程；管外的通道及與其相貫通的部分稱為殼程。一種流體在管內流動，優質換熱器哪家好而另一種流體在殼與管束之間從管外表面流過，換熱器哪家好為了保證殼(ke)程流體能夠(gou)橫向(xiang)流過(guo)管(guan)束(shu)(shu)，以形成較(jiao)高的(de)(de)(de)傳(chuan)熱(re)(re)(re)(re)(re)速率，在外殼(ke)上裝有許多擋板。管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)管(guan)束(shu)(shu)腐蝕(shi)和磨蝕(shi)失(shi)(shi)效(xiao)的(de)(de)(de)主要原因(yin)管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)在使用的(de)(de)(de)過(guo)程中可能會發生失(shi)(shi)效(xiao)的(de)(de)(de)情況(kuang)，常(chang)見(jian)的(de)(de)(de)失(shi)(shi)效(xiao)是管(guan)束(shu)(shu)失(shi)(shi)效(xiao)的(de)(de)(de)情況(kuang)管(guan)束(shu)(shu)腐蝕(shi)和磨蝕(shi)失(shi)(shi)效(xiao)、傳(chuan)熱(re)(re)(re)(re)(re)能力(li)下降、管(guan)束(shu)(shu)泄漏.以下是關于(yu)管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)官(guan)術失(shi)(shi)效(xiao)的(de)(de)(de)具體介紹。管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)出現管(guan)束(shu)(shu)失(shi)(shi)效(xiao)的(de)(de)(de)情況(kuang)有哪(na)些?管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)的(de)(de)(de)失(shi)(shi)效(xiao)大多數(shu)是由腐蝕(shi)引起的(de)(de)(de)。最常(chang)見(jian)的(de)(de)(de)管(guan)殼(ke)式(shi)(shi)換熱(re)(re)(re)(re)(re)器(qi)腐蝕(shi)部位是換熱(re)(re)(re)(re)(re)管(guan),然(ran)后依次是管(guan)板、換熱(re)(re)(re)(re)(re)器(qi)封頭 及(ji)小直徑(jing)的(de)(de)(de)接管(guan)。
