Kuchetsa Kutentha Kuthana ndi Njira Yapamwamba

Kodi kutentha kotentha kumathandizira chiyani?

Kutentha Kwambiri Ndi njira yothetsera kutentha yomwe imalola kutentha kwazitsulo komwe kumayikidwa ndi magetsi. Njirayi imadalira mafunde amagetsi opangira magetsi kuti apange kutentha ndipo ndiyo njira yomwe amagwiritsidwa ntchito polumikizira, kuumitsa kapena kufewetsa zitsulo kapena zida zina zoyendetsera. M'machitidwe amakono opanga, njira iyi yothandizira kutentha imapereka kuphatikiza kopindulitsa, kuthamanga, kuwongolera. Ngakhale mfundo zake ndizodziwika bwino, kupita patsogolo kwamakono kwamatekinoloje olimba kwapangitsa kuti njirayi ikhale yosavuta, yotsika mtengo yotenthetsera ntchito zomwe zimaphatikizapo kujowina, kuchiritsa, kutentha ndi kuyesa zida.

Kuchepetsa kutentha kwanyumba, pogwiritsa ntchito koyilo yamagetsi yoyendetsedwa bwino, kumakupatsani mwayi wosankha mawonekedwe abwinobwino osakhala gawo limodzi lazitsulo zokha — koma gawo lililonse lazitsulo. Kuumitsa kwachangu kumatha kupereka kulimba kwakutali pamagazini okhala ndi magawo a shaft popanda kupereka ductility yofunikira kuthana ndi zovuta komanso kugwedera. Mutha kuumitsa malo okhala mkati ndi mipando yama valve muma mbali ovuta popanda kupanga zovuta zosokoneza. Izi zikutanthauza kuti mumatha kuumitsa kapena kulumikiza madera ena kuti mukhale okhazikika komanso kuti muzitha kuchita zinthu m'njira zomwe zingakwaniritse zosowa zanu.

Ubwino Wothandizira Kutentha Kuteteza Ntchito

  • Kuyang'ana Kutentha Kuumitsa kwapamwamba kumakhalabe ndi ductility yoyambirira pachimake pomwe kumawumitsa gawo lokwanira. Dera lolimba limayang'aniridwa molondola potengera kuzama kwamilandu, m'lifupi, malo ndi kuuma kwake.
  • Kukwanira Koyenera Chotsani zosasinthasintha komanso zovuta zomwe zimakhudzana ndi lawi lotseguka, kutentha kwa tochi ndi njira zina. Dongosololi likasankhidwa moyenera ndikukhazikitsidwa, palibe ntchito yongoyerekeza kapena kusiyanasiyana; kachitidwe kotenthetsako kakhoza kubwereza komanso kosasintha. Ndi machitidwe amakono olimba, kuwongolera kutentha kokwanira kumapereka zotsatira zake.

  • Kukula Kwambiri Mitengo yopanga itha kukulitsidwa chifukwa 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.
  • Kusintha Kwabwino Kwazochita Mbali sizikumana mwachindunji ndi lawi kapena chinthu china chotenthetsera; kutentha kumayambitsidwa mkati mwa gawo lomwelo posinthitsa magetsi. Zotsatira zake, kugwedezeka pazogulitsa, kusokoneza ndi kukana mitengo kumachepetsedwa.
  • Kuchepetsa Mphamvu Yogwiritsa Ntchito Wotopa ndi kuchuluka kwa ngongole zofunikira? Njira yapaderayi yogwiritsira ntchito magetsi imasinthira mpaka 90% yamagetsi omwe agwiritsa ntchito mphamvuyo kukhala kutentha; Ng'anjo zamagetsi nthawi zambiri zimakhala ndi mphamvu zokwanira 45% zokha. Palibe zozizira kapena zoziziritsa kukhosi zomwe zimafunikira kotero kuyimilira-kwakanthawi kochepetsa kutentha kumachepetsedwa kukhala kochepa.
  • Mwachikhalidwe Kuwotcha mafuta achikale sikofunikira, zomwe zimapangitsa kuti pakhale njira yoyera, yosadetsa yomwe ingathandize kuteteza chilengedwe.

Kodi Kutentha kwa Induction ndi chiyani?

Kutentha Kwambiri ndi Njira Yotenthetsera Yosayanjanitsika, yomwe imatenga mphamvu kuchokera ku Maginito Osiyanasiyana, opangidwa ndi Induction Coil (Inductor).

Pali njira ziwiri zopangira mphamvu:

  • Kutulutsa kwa mafunde otsekemera (eddy) mkati mwathupi omwe amachititsa kutentha chifukwa chamagetsi amakana thupi
  • Kutentha kwa hysteresis (kwa maginito PAMODZI!) chifukwa chakusokonekera kwama voliyumu am'maginito (madambwe), omwe amasunthira kutsatira maginito akunja

Mfundo Yotenthetsera

Unyolo wa zochitika:

  • Kuchulukitsa magetsi imapereka zamakono (I1) ku coil induction
  • Ma coil mafunde (ampere-kutembenukira) amapanga maginito. Mizere yam'minda nthawi zonse imatsekedwa (lamulo lachilengedwe!)
  • Maginito osinthasintha oyenda pakati pagawoli (kulumikizidwa ndi gawolo) amachititsa kuti gawolo likhale ndi gawo

  • Mphamvu zamagetsi zimapanga ma eddy (I2) mbali yomwe ikuyenda moyang'anizana ndi kolowera momwe zingathere
  • Mafunde a Eddy amatulutsa kutentha pang'ono

Kuyenda Kwamphamvu Pakukhazikitsa Kutentha

Kusintha kwamasinthidwe amasiku ano kumawongolera kawiri pafupipafupi. Ngati pafupipafupi ndi 1kHz, kusintha kwamakono kumawongolera maulendo 2000 pamphindi.

Chochokera pakali pano komanso pamagetsi chimapatsa mphamvu mphamvu pompopompo (p = ixu), yomwe imazungulira pakati pamagetsi ndi koyilo. Titha kunena kuti mphamvu ikuphatikizidwa pang'ono (Mphamvu Yogwira Ntchito) ndikuwonetsedwa pang'ono (Mphamvu Yogwiritsanso Ntchito) ndi koyilo. Batire ya Capacitor imagwiritsidwa ntchito kutsitsa jenereta pamagetsi ake. Ma capacitors amalandila mphamvu zotseguka kuchokera koyilo ndikuzibwezeretsa ku coil yothandizira oscillations.

Dongosolo "coil-transformer-capacitors" limatchedwa Resonant kapena Tank Circuit.
