Zosinthira kutentha kwa mbale zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuti zizitha kusamutsa kutentha bwino pakati pa madzi awiri. Zimadziwika ndi kukula kwake kochepa, kugwiritsa ntchito bwino kutentha kwambiri komanso kusamalitsa mosavuta. Ponena za zosinthira kutentha kwa mbale, mitundu iwiri yodziwika bwino ndi zosinthira kutentha kwa mbale zopakidwa gasket ndi zolumikizidwa. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ndikofunikira kwambiri posankha njira yoyenera kwambiri pa ntchito inayake.
Chosinthira Kutentha kwa Mbale Yokhala ndi Gasketed:
Mapangidwe a gasketed plate heat exchanger ali ndi ma plate angapo omwe amatsekedwa pamodzi ndi ma gasket. Ma gasket amenewa amapanga chitseko cholimba pakati pa ma plate, zomwe zimapangitsa kuti madzi awiriwa asasinthane. Ma gasket nthawi zambiri amapangidwa kuchokera ku zipangizo monga EPDM, nitrile rabara, kapena fluoroelastomer, kutengera momwe ntchito ikuyendera komanso madzi omwe akuyendetsedwa.
Chimodzi mwa ubwino waukulu wa zosinthira kutentha kwa mbale zokhala ndi gasket ndi kusinthasintha kwawo. Ma gasket amatha kusinthidwa mosavuta, zomwe zimapangitsa kuti azikonzedwa mwachangu komanso kuti azikhala ndi nthawi yochepa yogwira ntchito. Kuphatikiza apo, zosinthira kutentha kwa mbale zokhala ndi gasket ndizoyenera kugwiritsidwa ntchito komwe mikhalidwe yogwirira ntchito ingasiyane, chifukwa ma gasket amatha kusankhidwa kuti apirire kutentha ndi kupsinjika kosiyanasiyana.
Komabe, zosinthira kutentha kwa mbale zokhala ndi gasket zilinso ndi zofooka zina. Ma gasket amatha kuwonongeka pakapita nthawi, makamaka akakumana ndi kutentha kwambiri, zakumwa zowononga, kapena kutentha pafupipafupi. Izi zingayambitse kutuluka kwa madzi ndipo zimafuna kukonzedwa pafupipafupi.
Wowotcherera mbale kutentha exchanger:
Mosiyana ndi zimenezi, zosinthira kutentha kwa mbale zolumikizidwa zimapangidwa popanda ma gasket. M'malo mwake, mbalezo zimalumikizidwa pamodzi kuti zikhale zolimba komanso zokhazikika. Kapangidwe kameneka kamachotsa chiopsezo cha kulephera kwa gasket komanso kutuluka kwa madzi, zomwe zimapangitsa kuti zosinthira kutentha kwa mbale zolumikizidwa zikhale zoyenera kugwiritsidwa ntchito potentha kwambiri, madzi owononga, komanso zinthu zomwe zimapanikizika kwambiri.
Kusowa kwa ma gasket kumatanthauzanso kuti ma welded plate heating exchanger ndi opapatiza kwambiri ndipo ali ndi chiopsezo chochepa cha kuipitsidwa chifukwa palibe ma gasket grooves omwe amasunga. Izi zimapangitsa kuti zikhale zabwino kwambiri kugwiritsa ntchito komwe kuli malo ochepa komanso ukhondo ndi wofunikira.
Komabe, kusowa kwa ma gasket kumatanthauzanso kuti ma weld plate heating exchanger sasinthasintha kwambiri pankhani yokonza ndi kukonzanso. Ma plate akalumikizidwa pamodzi, sangasunthidwe mosavuta kuti ayeretsedwe kapena kukonzedwa. Kuphatikiza apo, mtengo woyamba wa weld plate heating exchanger nthawi zambiri umakhala wokwera kuposa wa gasketed plate heating exchanger chifukwa cha welding yolondola yomwe imafunika.
Kusiyana kwakukulu:
1. Kukonza: Zosinthira kutentha kwa mbale zokhala ndi gasketed zimakhala zosavuta kusamalira komanso zosinthasintha, pomwe zosinthira kutentha kwa mbale zokhala ndi welded zimakhala ndi kapangidwe kokhazikika komanso kopanda kukonza.
2. Mikhalidwe Yogwirira Ntchito: Zosinthira kutentha kwa mbale zokhala ndi gasketed ndizoyenera mikhalidwe yosiyanasiyana yogwirira ntchito, pomwezosinthira kutentha kwa mbale zolumikizidwandi oyenera kwambiri kugwiritsa ntchito kutentha kwambiri, kuthamanga kwambiri komanso madzi owononga.
3. Mtengo: Mtengo woyamba wa chosinthira kutentha cha mbale chopangidwa ndi gasketed nthawi zambiri umakhala wotsika, pomwe ndalama zomwe zimayikidwa pasadakhale za chosinthira kutentha cha mbale cholumikizidwa zitha kukhala zokwera.
Mwachidule, kusankha pakati pa zosinthira kutentha kwa mbale zokhala ndi gasketed plate ndi zosinthira kutentha kwa mbale zokhala ndi welded kumadalira zofunikira za ntchitoyo. Zosinthira kutentha kwa mbale zokhala ndi gasketed plate zimapereka kusinthasintha komanso kusamalika kosavuta, pomwe zosinthira kutentha kwa mbale zokhala ndi welded plate zimapereka yankho lamphamvu komanso lokhalitsa pamavuto ogwirira ntchito. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ndikofunikira kwambiri posankha njira yoyenera kwambiri yosamutsira kutentha moyenera komanso modalirika m'mafakitale osiyanasiyana.
