Phindu la Kutentha Kwambiri

Kodi kupindula ndi kutentha kotsekemera ndi chiyani?, kupukuta, kuumitsa, kusungunula ndi kumangirira, ndi zina zotero?

Bwanji osankha kutentha kwakupangira pazitsulo zotseguka, convection, radiant kapena njira yowonjezera? Apa pali chidule cha ubwino waukulu womwe masiku ano kutentha kotentha kwapadera kumapangidwira kupanga mafakitale:

* Kutentha Kwambiri

Kutentha Kwambiri imakakamizidwa mkati mwa gawo lomwelo posinthitsa magetsi. Zotsatira zake, kugwedezeka pazogulitsa, kusokoneza ndi kukana mitengo kumachepetsedwa. Kuti mukhale ndi malonda abwino kwambiri, gawolo limatha kupatulidwa m'chipinda chotsekedwa ndi zingalowe, kulowa mkati kapena kuchepetsa mpweya kuti muchepetse zovuta za makutidwe ndi okosijeni. Mitengo yopanga itha kukulitsidwa chifukwa kupatsidwa ulemu kumagwira ntchito mwachangu kwambiri; kutentha kumapangidwa mwachindunji komanso nthawi yomweyo (> 2000º F. mu <1 sekondi) mkati mwa gawolo. Kuyamba kumakhala pafupifupi nthawi yomweyo; palibe kutentha kapena kutentha komwe kumafunika. Makina otenthetsera amatha kumalizidwa pansi, pafupi ndi makina ozizira kapena otentha, m'malo motumiza zigawo zingapo kumalo oyaka moto kapena subcontractor. Mwachitsanzo, njira yolimbitsira kapena kusungunula yomwe kale imafuna njira yowotchera nthawi yayitali, yotchinga ndi batch tsopano ikhoza kusinthidwa ndi njira yopitilira imodzi.

* Kutentha Mogwirizana

Kutentha kotentha kumathetsa kusagwirizana ndi nkhani zomwe zimakhudzana
ndi lotsegula, kutentha kwa ng'anjo ndi njira zina. Pokhapokha dongosololi litakonzedweratu ndi kukhazikitsidwa, palibe kulingalira ntchito kapena kusintha; njira yotentha imagwiritsidwa ntchito mobwerezabwereza. Ndi zowonongeka zamakono zamasiku ano, kuyendetsa bwino kutentha kumapereka zotsatira zowunifolomu; mphamvu ikhoza kutsegulidwa nthawi yomweyo kapena kutseka. Ndi kutseka kutsekedwa kwa kutentha kwa kutentha, kupita patsogolo kuyambitsa kutentha kayendedwe kachitidwe ali ndi luso loyesa kutentha kwa gawo lililonse. Mitundu yokhayo, yolembera ndi kutsika mitengo imatha kukhazikitsidwa & zambiri zitha kujambulidwa pagawo lililonse lomwe likuyendetsedwa.

* Kutentha Woyera

Kutsatsa njira zotentha musatenthe mafuta atsopano; Kupititsa patsogolo ndi njira yoyera, yopanda kuipitsa yomwe ingathandize kuteteza chilengedwe. Ndondomeko yochepetsedwera imathandiza kuti ogwira ntchito anu azikhala ndi kuthetsa utsi, kutentha kwazitayira, mpweya woipa komanso phokoso lalikulu. Kutentha kumakhala kosavuta komanso kosavuta popanda moto wowatseguka kuti uwononge wogwiritsira ntchito kapena kusokoneza njirayo. Zida zosagwira ntchito sizimakhudzidwa ndipo zimapezeka pafupi ndi malo otenthetsera popanda kuwonongeka.

* Sungani Mphamvu

Mukutopa ndi ndalama zowonjezera zowonjezera? Njira yokhayi yowonjezera mphamvuyi imatembenukira ku 90% ya mphamvu yowonjezera mphamvu kukhala yotentha; Nkhumba zotentha ndizochepa 45% yowonjezera mphamvu. Ndipo popeza kutengeka sikufuna kutenthetsa kapena kuzizira, kuyima kwa kutentha kumachepetsedwa kukhala kochepa. Kubwezeretsa ndi kusasinthasintha kwa pulojekitiyi kumapangitsa kuti zikhale zovomerezeka kwambiri ndi zogwiritsira ntchito zowonongeka.

Kodi Kutentha Kumakhala Chiyani?

Kodi Kutentha Kumakhala Chiyani?

Kutentha Kwambiri ndi njira yotentha chinthu chopangira magetsi (kawirikawiri chitsulo) ndi makina opangira magetsi, komwe kumathamanga mazira (omwe amatchedwanso Foucault mafunde) amachititsa kuti zitsulo zitsulo zisamangidwe ndipo zimayambitsa kutentha kwa Joule. kumayang'ana kuzungulira coilisi, kuyendetsa pakali pano (kutengeka, pakali pano, eddy wamakono) kumapangidwira mu workpiece (kutulutsa zinthu), kutentha kumatulutsidwa monga momwe mpweya umayendera motsutsana ndi ubwino wa nkhaniyo.Mfundo zoyambirira zowonjezera kutentha amamvetsetsa ndikugwiritsidwa ntchito popanga zinthu kuchokera ku 1920s. Panthawi ya nkhondo yachiŵiri ya padziko lonse, lusoli linakula mofulumira kuti likhale ndi nthawi yeniyeni yolimbana ndi nthawi yolimbana ndi njira yowonjezera, yodalirika yopangira zipangizo zamagetsi zamphamvu. Posachedwapa, kuyang'ana pa njira zowonongeka bwino ndikugwiritsidwa ntchito pazowonjezereka bwino zapamwamba zachititsa kuti pakhale njira yowonjezeredwa ya zipangizo zamakono, kuphatikizapo chitukuko choyendetsedwa bwino, zonse zopangira mphamvu zowonjezera.

Kodi Kutentha Kwambiri Kumagwira Ntchito Motani?

An mpweya wotentha (kwa njira iliyonse) ili ndi coil induction (kapena electromagnet), kudzera mwachitsulo chosinthika chapamwamba (AC). Kutentha kungathenso kupangidwa ndi maginito hysteresis kutaya mu zipangizo zomwe zili ndi chiwerengero chokwanira chokhazikika. Kuthamanga kwa AC kugwiritsidwa ntchito kumadalira kukula kwa chinthu, mtundu wa zinthu, kugwirizanitsa (pakati pa chophika ntchito ndi chinthu choti chikhale mkangano) ndi kuya kwa penetration.High Frequency Induction Kutentha ndi njira yomwe amagwiritsidwa ntchito kugwirizana, kuumitsa kapena kuchepetsa zitsulo kapena zipangizo zina zoyendetsa. Kwa njira zamakono zamakono zopangira, kutenthetsera mowa mwauchidakwa kumaphatikizapo kuphatikiza kokongola, kusasinthasintha ndi kulamulira.

Zomwe Zimatenthe Kutentha Mapulogalamu

Kutentha Kwambiri ndiwotchi, yoyera, yopanda kuipitsa mawonekedwe omwe angagwiritsidwe ntchito kutenthetsa zitsulo kapena kusintha katundu. Chophimbachokha sichitha ndipo mphamvu yotentha imayang'aniridwa. Mphamvu yolimbitsa thupi yotchedwa transistor teknoloji yathandiza kutentha kwambiri, kutentha kwapadera kwa ntchito, kuphatikizapo soldering, kutsekemera, kutentha, kutentha, kutsekemera, ndi zina zotero.
