Principle of water cooling system for induction melting furnace
Mfundo ya dongosolo loziziritsira madzi la ng’anjo yosungunula induction:
1. Mfundo ya dongosolo madzi kuzirala kwa chowotcha kutentha:
Madzi ogwira ntchito amazungulira mu koyilo ya nsanja yotsekedwa yozizira, kutentha kwamadzimadzi kumasunthidwa kudzera pakhoma la chubu, ndikupanga nthunzi yodzaza ndi madzi ndi mpweya. Panthawi yozungulira, madzi opopera amachepetsa kutentha kwa madzi kudzera mu sinki ya kutentha ya PVC, ndipo amapanga mphepo ndi madzi oyendayenda mofanana ndi mpweya watsopano womwe ukubwera. The koyilo makamaka amadalira mwanzeru kutentha conduction.
2. Mawonekedwe a mpweya wolowera m’madzi ozizira a ng’anjo yosungunula yosungunula: mawonekedwe amagulu otuluka kuchokera mbali imodzi ya mphepo ndi madzi.
3. Ubwino wa makina oziziritsira madzi a ng’anjo yosungunula:
a. Dongosolo loziziritsa madzi la ng’anjo yosungunuka ya induction ndilosavuta kusamalira:
① Danga lalikulu la nsanjayo limapereka mwayi wosinthika pakukonza zida, ndipo ma coils, mbale zosungira madzi, masinki otentha a PVC, ndi zina zotere zitha kusungidwa munsanja.
② Zigawo zazikulu – kukonza koyilo ndikosavuta chifukwa cha kapangidwe kake ka zida, ndipo gulu limodzi la ma coil limatha kutulutsidwa kunja kwa nsanja kuti likonze.
③ Mipopu yopopera, mapaipi opopera ndi akasinja amadzi a makina opopera amakhala ndi nthawi yosamalira kwambiri, pomwe makina opopera amawonekeratu, ndipo pali zotchingira zapadera ndi makwerero operekera kusavuta, komwe ndikosavuta.
b. Njira yoziziritsira madzi ya induction kusungunula m’ng’anjo kuti mupewe makulitsidwe:
Zinsanja zozizirirapo zotsekera zotsekeka zotsekereza sizinakhalepo ndi njira yabwino yopewera kukulitsa koziziritsa. Chogulitsachi ndicho chinthu chachikulu kwambiri cha mankhwalawo pothana ndi makulitsidwe a koyilo yozizirira. Zinthu zake ndi izi:
① Madzi opopera amayenda mbali imodzi ndi mpweya watsopano, kotero kuti madzi opopera amatha kukulunga khoma lakunja la chitoliro ndikunyowetsa kwathunthu, kupewa kupanga mawanga owuma kumunsi kwa chitoliro ngati zinthu zofananira. njira yotsutsa, ndikupewa malo owuma. Sikelo imapangidwa.
② Kutentha kwamadzi otsika kumapangitsa kukhala kovuta kwa zinthu za calcium ndi magnesium crystalline zomwe zimakhala zosavuta kupanga masikelo kuti zigwirizane ndi chitoliro chachitsulo, kupewa kudzikundikira kwa sikelo. Chigawo cha kutentha kwa PVC chomwe chimakonzedwa muzipangizocho chimagwiritsidwa ntchito kuchepetsa kutentha kwa madzi.
③ Njira yosinthira kutentha ndi kusinthanitsa kutentha kupyolera mu kutentha kwabwino kwa chitoliro chonyowa ndi kutentha kobisika kwa khoma la chitoliro chotengera kutentha, chomwe chimakhala chothandiza kupewa kukulitsa.
