板式換熱器本身技術指標上存在過流孔徑,進水水質請求,經過比照實踐進水水質指標(冷水進水水質,熱水進水水質),需求留意一下幾點：半容積式熱交換器價格進水水質酸堿性(包括冷水和用于換熱的熱水),假如超出板式換熱器進水技術指標,需求加裝PH調理安裝,避免過酸腐蝕或者過堿構造梗塞;同事堿性也會腐蝕換熱器密封橡膠圈招致走漏呈現.假如進水濁度超標或進水中雜質過多過大(包括冷水和用于換熱的熱水),倡議加裝自清洗過濾器,避免板式換熱器梗塞,假如影響不是很大,只需在進水端加裝Y型過濾器即可.華北半容積式熱交換器價格閉路循(xun)環要思索增加(jia)加(jia)藥安裝,如投加(jia)緩蝕阻(zu)垢劑(ji)避免結垢。
