(HL)、低 (LL)3種特性的流道，知足不同工況的需求。板片材質(zhì)可選擇奧氏體不銹鋼、鈦合金、銅合金等。板片厚度對傳熱系數(shù)影響很大，厚度減小 0.1mm ，對稱型板式換熱器的總傳熱系數(shù)約增加 600W/(m·K) ，非對稱型約增加 500 W/(m·K)。因為可拆式板式換熱器便于拆卸清洗，增減換熱器面積靈活，在供熱工程中使用較多。因為板換式換熱器的波紋能使流體在較小的流速下產(chǎn)生湍流 (雷諾數(shù)—150 時) ，因此能獲得較高的表面?zhèn)鳠嵯禂?shù)，表面?zhèn)鳠嵯禂?shù)與板片波紋的幾何結(jié)構(gòu)以及介質(zhì)的活動狀態(tài)有關(guān)。有些供熱單位為防止盜水及鋼件侵蝕，在供熱介質(zhì)中添加藥劑，因此必需留意水質(zhì)和黏粘劑引起雜物沾污換熱器板片。福田區(qū)換熱器哪里有賣板式換熱器屬于緊湊式換熱器，主要是與管殼式換熱器進行比較，傳統(tǒng)的管殼式換熱器占地較大。</p><div

style="text-indent:25px">關(guān)于板式換熱器的零件組裝，無論是制造廠向使用單位發(fā)運零件，進行現(xiàn)場組裝，還是使用單位在檢修設(shè)備拆開板式換熱器后再組裝，都必須按照以下順序進行。 1、認(rèn)真閱讀隨機文件（合格證、材質(zhì)證、流程圖、裝配圖和裝箱清單等）。 2、檢查板片、接管、墊片的材質(zhì)是否與換熱器內(nèi)介質(zhì)的耐腐蝕要求相一致。 3、按圖紙檢查所有的零件是否齊全，型號、尺寸是否與圖紙相符。 4、將板片的墊片槽擦干凈，均勻地涂上粘接劑，粘上墊片，然后把板片整齊地疊放在一起，壓上一定的重物。 5、按設(shè)計的流程圖進行組裝，并按規(guī)定順序進行夾緊。夾緊時，應(yīng)先擰緊1、2、3、4號螺母，然后再擰緊5、6、7、8、9、10號螺母。 6、液壓試驗要按單側(cè)分別進行。試驗壓力為設(shè)備設(shè)計壓力的1.25倍；保壓30min,檢查所有密封盒焊接部位，均無滲漏為合格。</p><p style="text-indent:25px">流程指板式換熱器內(nèi)一種介質(zhì)同比較好動方向的一組并聯(lián)流道，而流道指板式換熱器內(nèi)，相鄰兩板片組成的介質(zhì)流動通道。一般情況下，將若干個流道按并聯(lián)或串聯(lián)的方式連接起來，以形成冷、熱介質(zhì)通道的不同組合。流程組合形式應(yīng)根據(jù)換熱和流體阻力計算，在滿足工藝條件要求下確定。盡量使冷、熱水流道內(nèi)的對流換熱系數(shù)相等或接近，從而得到較佳的傳熱效果。因為在傳熱表面兩側(cè)對流換熱系數(shù)相等或接近時傳熱系數(shù)獲得較大值。雖然板式換熱器各板間流速不等，但在換熱和流體阻力計算時，仍以平均流速進行計算。由于“U”形單流程的接管都固定在壓緊板上，拆裝方便。在板式換熱器的設(shè)計選型時，一般對壓降有一定的要求，所以應(yīng)對其進行校核。如果校核壓降超過允許壓降，需重新進行設(shè)計選型計算，直到滿足工藝要求為止。板式換熱器較為重要的部件是換熱板片和密封墊片。</p><div

1、拆下廢舊墊片。注意拆卸時，不得使墊片槽內(nèi)有劃痕。 2、用**、**或其它酮類溶劑，去除墊片槽內(nèi)的殘膠。 3、用干凈的布或者是棉紗擦凈墊片槽和墊片。 4、將粘接劑均勻地涂在墊片槽內(nèi)。 5、把干凈的新墊片貼在板上。 6、貼好墊片的板片要放在平坦、陰涼、通風(fēng)的地方自然干固4h后才可安裝使用。對于介質(zhì)流量和壓力變化較大、而且又是多程組合、長期使用的板式換熱器，容易發(fā)生板片錯位現(xiàn)象。板片錯位后，有時很快就出現(xiàn)外漏；有些雖然不是立即發(fā)生外漏，但卻是發(fā)生滲漏的一種隱患，所以都必須及時處理。裝換熱器的基礎(chǔ)必須滿足以使換熱器不發(fā)生下沉。深圳容積式換熱器費用哪家便宜</p><p
