【膠合板熱(re)(re)壓(ya)機廠家介紹】加熱(re)(re)或冷(leng)(leng)卻溫(wen)度(du)控制(zhi)，在要加熱(re)(re)冷(leng)(leng)卻交替(ti)進(jin)行(xing)的場合,用蒸汽(qi)加熱(re)(re)法,得首(shou)先關閉蒸汽(qi)閥(fa),減小熱(re)(re)壓(ya)板中的蒸汽(qi)壓(ya)力,而(er)(er)后慢(man)慢(man)打開放(fang)汽(qi)閥(fa),漸(jian)漸(jian)放(fang)走(zou)熱(re)(re)壓(ya)板中的蒸汽(qi),然后再(zai)壓(ya)入冷(leng)(leng)卻水(shui)(shui)進(jin)行(xing)冷(leng)(leng)卻。相(xiang)反,加熱(re)(re)時,先得用蒸汽(qi)把冷(leng)(leng)卻水(shui)(shui)頂出去(qu),此時,水(shui)(shui)在高溫(wen)孔(kong)道中局(ju)部急劇(ju)蒸發(fa)而(er)(er)產生(sheng)“水(shui)(shui)錘”現象。同(tong)時冷(leng)(leng)卻水(shui)(shui)中的雜質(zhi)附在熱(re)(re)孔(kong)壁上,使(shi)傳熱(re)(re)性(xing)能惡化,并使(shi)熱(re)(re)壓(ya)板產生(sheng)變形。而(er)(er)用過熬水(shui)(shui)加熱(re)(re)時,只(zhi)要控制(zhi)閥(fa)門,切換高溫(wen)低溫(wen)水(shui)(shui),或者(zhe)混合流(liu)動,即可(ke)實現可(ke)調(diao)節的加熱(re)(re)和冷(leng)(leng)卻。在溫(wen)度(du)控制(zhi)方面,蒸汽(qi)加熱(re)(re),一(yi)般只(zhi)能以控制(zhi)其流(liu)量(liang)來調(diao)節溫(wen)度(du);而(er)(er)過熱(re)(re)水(shui)(shui)加熱(re)(re),除控制(zhi)流(liu)量(liang)外,還可(ke)以用改變循環過熱(re)(re)水(shui)(shui)的溫(wen)度(du)來控制(zhi),所(suo)以更能嚴(yan)格地(di)控制(zhi)溫(wen)度(du)。
