style="text-indent:25px">板式換熱器是用薄金屬板(一般為不銹鋼)壓制成具有一定形狀波紋的換熱板片,然后加密封膠墊疊裝而成的一種換熱器。主要由傳熱片、密封膠墊、夾緊螺栓、壓緊板、整機(jī)框架等零部件組成。冷熱介質(zhì)通過(guò)相鄰換熱板片流經(jīng)各自通道,中間通過(guò)一層薄換熱板片進(jìn)行換熱,因此高效節(jié)能,換熱系數(shù)高,使用安全可靠,結(jié)構(gòu)緊湊,體積小,占地少,組合靈活,調(diào)整維修方便。板式換熱器一般可分為:水-水交換和汽-水交換兩種方式。水-水交換方式冷熱介質(zhì)均為水,且冷熱水溫差不,大概在70～90℃之間,兩邊結(jié)垢情況基本相同;汽-水交換方式熱介質(zhì)為水蒸汽,一般不易結(jié)垢,冷介質(zhì)為水,溫度約90℃ ,易結(jié)垢。板式換熱器的設(shè)計(jì)我們可以根據(jù)對(duì)數(shù)溫差來(lái)確定是用什么樣的槽深。仁化換熱器生產(chǎn)廠家</p><p style="text-indent:25px">板式換熱器在使用過(guò)程中，無(wú)論是板片發(fā)生變形、裂紋、穿孔，還是墊片發(fā)生老化、斷裂，都需要及時(shí)更換。廣州換熱器作用有哪些</p><p style="text-indent:25px">板式換熱器的外漏這是指板式換熱設(shè)備內(nèi)的介質(zhì)向外部空間的滲漏。這種滲漏現(xiàn)象一般容易發(fā)現(xiàn)。引起這種滲漏的主要原因是墊片老化、被腐蝕或板片變形。當(dāng)發(fā)生這種滲漏時(shí)，應(yīng)及時(shí)在滲漏部分做上記號(hào)，打開(kāi)設(shè)備以更換墊片或板片。板式換熱器的內(nèi)漏這是指換熱設(shè)備內(nèi)的兩種介質(zhì)由于某種原因造成高壓側(cè)介質(zhì)向低壓側(cè)滲漏。這種滲漏現(xiàn)象一般不易及時(shí)發(fā)現(xiàn)。引起這種滲漏的主要原因是板片穿孔、裂紋和被腐蝕。發(fā)現(xiàn)這種滲漏的方法是要經(jīng)常對(duì)低壓側(cè)的介質(zhì)進(jìn)行化驗(yàn)，從其組分的變換中加以判斷。這種滲漏的停機(jī)檢查方法是： (1)、拆開(kāi)板式換熱器，去除板片表面上的污垢，擦干后將換熱器重新組裝起來(lái)。在一側(cè)進(jìn)行壓力為0.2~0.3Mpa的水壓試驗(yàn)。待另一側(cè)流出水后即停止試驗(yàn)，打開(kāi)換熱器，仔細(xì)觀察板片的未試壓側(cè)，其中濕的板片即為有孔或裂紋的板片。 (2)、在現(xiàn)場(chǎng)也可用透光、著色檢查方法，查出廢板片。凡檢查出來(lái)的廢板片和墊片都要進(jìn)行更換，重新組裝后使用。廣州換熱器作用有哪些</p><p
