1、挖孔：在確定了最好熱水機組內漏點的位置后,從換熱器外層對應著漏點的地方,開始割孔,順序是由外向里,一直割到有內漏點的那一層為止。割出的孔應為橢圓形,且尺寸的大小是外層大,向里逐漸小,一般每層板上孔的大小相差40mm,如漏點位置較深,在外層割出的孔應較大。換熱器內漏處的3種處理辦法2、清渣：在割完孔后,應對留在每層板上的氧化渣認真進行清理,這是在對焊回補板時,回補板與每層螺旋板能否貼緊焊牢的關鍵,可用鏨子和修整模具用的小手砂輪清理氧化渣,注意應盡量將清理的渣子清出,不讓其掉進換熱器內。換熱器內漏處的3種處理辦法3、配回補板：換熱器內漏處的3種處理辦法為保證修理的質量,從換熱器上每層割下來的板料,不再使用,【主詞廠家】重新配回補(bu)(bu)板(ban),另配的回補(bu)(bu)板(ban)要用(yong)與換熱器螺旋板(ban)相同的材(cai)料和板(ban)厚,其(qi)周(zhou)邊應比(bi)換熱器上每層(ceng)割出(chu)的孔分別大15mm-20mm,且也為橢(tuo)圓形,并做成和換熱器每層(ceng)螺旋板(ban)弧(hu)度(du)相一致的弧(hu)形。
