Bimetallic mbale: chipangizo, ntchito, ntchito zothandiza

Machitidwe okonzedwa bwino omwe amachititsa kuti kusintha kwa mawonekedwe ena apangidwe kumamangidwa pa zinthu zosavuta. Iwo ali ndi udindo wosintha chimodzi mwa magawo awo (mawonekedwe, voliyumu, magetsi opangira magetsi, ndi zina zotero) pansi pa mphamvu imodzi kapena zingapo.

Choncho, zipangizo zamakono zatsopano zotentha zimakhala ndi zipangizo zotentha zomwe zimawongolera kuchuluka kwa kutentha kwapansi. Maziko a chipangizo chili chonse ndi mbale ya bimetallic.

Kodi bimetallic mbale ndi chiyani?

Chinthu chomwe chili ndi vuto la kupunduka (kutchingira) kumbali imodzi mothandizidwa ndi kutentha kwapamwamba kumatchedwa mbale ya bimetallic. Dzina, mungathe kuganiza kuti mapangidwe a mbaleyo ali ndi zitsulo ziwiri. Mmodzi wa iwo ali ndi phindu lenileni la coefficient of thermal expansion. Chotsatira chake, pamene imodzi mwa mbaleyi ikuwotchedwa, gawo limodzi la izo likuwonjezeka ndi kuchuluka kwina, ndi lina ndi lina.

Izi zimayambitsa kupindika, mawonekedwe ake omwe zimadalira kusiyana kwa kutentha kwa coefficients. Mlingo wa deformation ndi wosiyana kwambiri ndi kusintha kwa kutentha. Pamene mbaleyo itakhazikika, imapeza malo ake oyambirira. Mbalewo ndi mgwirizano wa monolithic ndipo ukhoza kugwira ntchito malinga ngati ukufunira.

Ndi zigawo zikuluzikulu zomwe zimagwiritsidwa ntchito muzinthu zamakono

Pofuna kugwirizanitsa zitsulo pamodzi, zimakhala zogwiritsidwa ntchito.

Chitsanzo cha mbale ya bimetallic yodziwika ndi kugwirizana kwa mkuwa ndi zitsulo. Zambiri zoterezi zili ndi kutentha kwakukulu.

Pali mafananidwe a bimetal kuchokera ku zinthu zopanda malire (galasi, keramiki). Zimapangidwa kuti zigwire ntchito zamagetsi zomwe zitsulo sizingagwiritsidwe ntchito.

Kodi bimetallic mbale imagwira ntchito bwanji?

Chipinda chopangidwa ndi bimetal chimagwira ntchito monga mbali zosiyanasiyana za kayendedwe ka kutentha ndi kuyendetsa kutentha, kapena kuposa momwe zimasinthira zambiri. Kutentha kosavuta kumaphatikizapo:

• Thupi lopanda kutentha. Ili ndi zinthu zonse zomwe zikutumizira.
• Zomalizira - zimagwiritsidwa ntchito polumikiza dera lamagetsi.
• Mankhwala amasintha kwa olankhulana kapena magulu olankhulana. Tsekani ndi kutsegula makina opangira magetsi, kuphatikizapo kapena kutsegula dera.
• Dongosolo la dielectric kapena gasket. Amatumiza mawotchi kuchokera ku mbale kupita kumsinkhu.
• Bimetallic mbale. Ndi chinthu chofunika kwambiri pa kusintha kwa kutentha ndipo kumayambitsa kukakamiza pa ndodoyo.
• Kutentha mphamvu. Chipangizo chachitsulo chachilendo, cholumikizidwa mwachindunji ku gawo lolamulira. Ali ndi mautentheni abwino omwe amachititsa kutentha kwa bimetal.

Pamene pamwamba pa chowotcha chimakhala ndi kutentha kovomerezeka, bimetallic mbale ili mu malo otsika (otsika), makina ogwiritsira ntchito magetsi amatsekedwa, pakali pano akuyenda mu dera lotentha.

Pamene kutentha kwapamwamba kumatuluka, bimetal imayamba kuphulika ndipo pang'onopang'ono imafa, imayesetsa kukakamiza ndodoyo. Pa nthawi yomweyo, nthawi ikubwera pamene ndodo imatsegula kukhudzana ndi mawotchi, ndipo pakali pano mumsewu wotentha umatsekedwa. Kenaka imatha pansi, mapulumuwo amatha, kutsekedwa kwachitsulo, ndi chirichonse chimabwereza kachiwiri.

Kawirikawiri zotumizira zimatulutsidwa ndi kukhoza kuyendetsa kutentha kwa kutentha.

Bimetallic boiler mbale

Machitidwe otentha a gasi ndi zipangizo zoopsa kwambiri, motero zimaphatikizapo mitundu yosiyanasiyana yowonongeka. Kotero, chinthu chachikulu cha chitetezo ndi chopangira mphamvu. Icho chimapereka njira yolondola ya zotsatira za zotenthedwa, zomwe zimachokera ku chipinda choyaka moto kupita ku chimbudzi. Izi zimateteza mpweya monoxide kulowa m'chipindamo ndi kupha anthu.

Cholinga chachikulu cha chojambulira chithunzithunzi ndi mbale ya bimetallic yophikira mafuta. Mfundo yake ikufanana ndi bimetal iliyonse, ndipo miyeso ndi magawo a zinthuzo amawerengedwa m'njira yomwe imatha kutentha kwa madigiri 75 mu msewu amatsogolera ku deta ndi ntchito ya valve yamagetsi.

Ndi zipangizo ziti zomwe zimagwiritsa ntchito bimetal

Malo ogwiritsira ntchito bimetallic mbale ndi wodabwitsa kwambiri. Pafupifupi zipangizo zonse zomwe zimafunika kutentha kutentha zimakhala ndi zipangizo zozizira. Izi zimakhala chifukwa chophweka ndi chodalirika cha machitidwe oterewa. Mu telojiya yamakono, kuima kwazitsulo:

• Mu zipangizo zowonongeka m'nyumba: ovuni, kayendedwe ka zitsulo, ma boilers, kettles zamagetsi, ndi zina zotero.
• Kutentha: magetsi opangira magetsi, gasi komanso ma boilers olimba ndi magetsi.
• Mu electropackets ya kutseka kokha.
• Mu zamagetsi mu zipangizo zoyeza, komanso mu magetsi oyendetsa ndege ndi nthawi yotumizira.
• Mu injini yamtundu wotentha.

Mu zipangizo zamakinale, mbale zowonjezera zimayikidwa muzitsulo zomwe zimatetezera magetsi amphamvu kuchokera ku kutentha kwakukulu: zotengera, magetsi, mapampu, ndi zina zotero.

Pamene mbaleyo isinthidwa

Mabala onse a bimetallic amakhala ndi moyo wautali, koma nthawi zina kubwezeretsa kwake sikungapeweke. Zofunikira zimabwera pamene:

• Bimetal yataya katundu wake kapena wasintha, zomwe sizigwirizana ndi momwe ntchitoyo imagwirira ntchito.
• Chipindacho chinatenthedwa (chimatanthawuza kutenthetsa kwa mafuta).
• Ngati kachipangizo kowonongeka kawonongeka kapena galimoto yosungirako zidalephereka (mu mafuta otentha).
• Pamene malo omwe amagwiritsidwa ntchito pa mbale amapangidwira kukhala ntchito zowonongeka nthawi zonse.

M'zipangizo zam'nyumba nthawi zambiri sizimasintha. Ngati pulogalamu yotentha ikulephera, ndiye kuti m'malo mwa bimetallic pake pamakhala malo osungirako zinthu, omwe amapita ngati gawo lina la chipangizocho. Koma kawirikawiri chifukwa cha kulephera kwa chipangizocho ndi kutsegula kwa osonkhana oyambirira, osati bimetallic mbale.
