style="text-indent:25px">保持板片的清潔是保持高傳熱系數(shù)的重要條件之一。在板片間，介質(zhì)是沿著狹窄曲折的流道運(yùn)動(dòng)的，即使產(chǎn)生不太厚的垢層，也將引起流道的變換，明顯地影響流體的運(yùn)動(dòng)，使壓降增大、傳熱系數(shù)下降。例如某糖廠在采暖中使用板式換熱器，由于二次水沒有很好地處理，使用過程中*兩個(gè)月就將整個(gè)流道堵塞，不能繼續(xù)運(yùn)行?；瘜W(xué)清洗法的這種方法是將一種化學(xué)溶液循環(huán)地通過換熱器，云浮換熱器供應(yīng)商，使板片表面的額污垢溶解、排出。此法不需拆開換熱器，簡(jiǎn)化了清洗過程，也減輕了清洗的勞動(dòng)強(qiáng)度，云浮換熱器供應(yīng)商。由于板片波紋能促進(jìn)清洗液劇烈湍流，云浮換熱器供應(yīng)商，有利于垢層溶解，所以化學(xué)清洗法是比較理想的方法。板式換熱器結(jié)構(gòu)緊湊。云浮換熱器供應(yīng)商</p><div

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。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。凡檢查出來的廢板片和墊片都要進(jìn)行更換，重新組裝后使用。云浮換熱器供應(yīng)商板式換熱器的密封墊片主要是在換熱板片之間起密封作用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">板式換熱器按照有無鞍式支架分為兩種安裝方式。一種是對(duì)于沒有鞍式支架的板式換熱器，應(yīng)把換熱器安裝在磚砌的鞍形基礎(chǔ)上，安裝后的板式換熱器此刻不用與基礎(chǔ)固定，整個(gè)板換可隨著膨脹的改變自由移動(dòng)。第二種，對(duì)于有鞍式支座的板換，應(yīng)首先在基礎(chǔ)上平鋪混凝土，待完全干透后用地腳螺栓將鞍式支座與地面混凝土完全固定起來。在安裝板式換熱器的過程中，應(yīng)在換熱器前后兩端留出足夠的空間以便維護(hù)和清洗。換熱器不得在超過銘牌規(guī)定的條件下運(yùn)行，對(duì)于換熱器介質(zhì)的溫度和壓力要進(jìn)行察看和分析，防止換熱器出現(xiàn)異常運(yùn)行情況。換熱器的換熱效果和水垢有很大關(guān)系，水垢越多，換熱效果越不理想。因此，對(duì)于換熱片上的水垢要及時(shí)清洗。以免積垢過多影響換熱效果。</p><p style="text-indent:25px">換熱器的用材的選擇：使用何種材料的決定因素是其經(jīng)濟(jì)性,管子材料有不銹鋼,銅鎳合金,鎳基合金,鈦和鋯等,除了工業(yè)上不能使用焊接管的情況以外都使用了焊接管,耐蝕材料*用于管程,殼程材料是碳鋼。換熱器的金屬腐蝕：金屬腐蝕的原理金屬腐蝕是指在周圍介質(zhì)的化學(xué)或電化學(xué)的作用下,并且經(jīng)常是在和物理、機(jī)械或生物學(xué)因素的共同作用下金屬產(chǎn)生的破壞,也即金屬在它所處環(huán)境的作用下所產(chǎn)生破壞。換熱器幾種常見的腐蝕破壞類型均勻腐蝕在整個(gè)暴露于介質(zhì)的表面上,或者在較大的面積上產(chǎn)生的,宏觀上均勻的腐蝕破壞叫均勻腐蝕。板式換熱器中的冷熱流體流動(dòng)與換熱器中的冷熱流體流動(dòng)是平行的。</p><div

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(hào)、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(jì)的流程圖進(jìn)行組裝，并按規(guī)定順序進(jìn)行夾緊。夾緊時(shí)，應(yīng)先擰緊1、2、3、4號(hào)螺母，然后再擰緊5、6、7、8、9、10號(hào)螺母。 6、液壓試驗(yàn)要按單側(cè)分別進(jìn)行。試驗(yàn)壓力為設(shè)備設(shè)計(jì)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。在各個(gè)板式散熱片之間進(jìn)行密封的彈性密封墊是一種易損件，并且在自然條件下也是一種易于老化的零件。云浮換熱器供應(yīng)商</p><p
