Abscot: Kutentha kwa kutentha kwa mizere ya mpweya kumatheka pogwiritsa ntchito mphepo yachilengedwe kuti iyambe kuziziritsa kukhomeredwa. Madzi ozizira a dielosel amazimitsidwa ndi ozizira kuzungulira thanki yamadzi ndi silinda, pomwe mafuta ozizira a dielosel amakhazikika ndi mafuta a injiniya. Njira yozizira yomwe imagwiritsidwa ntchito pa mtundu uliwonse wa jenesel imatengera zinthu zomwe zimapangidwira mu seeler, ndipo pakugwiritsa ntchito njira zitatu zozizirazi. Ubwino wa injini zokhala ndi mpweya ndikuti ali ndi mawonekedwe osavuta ndipo safuna zowonjezera zowonjezera. Zipsezi zotentha pa cylinder block ndi nellinder mutu zimatha kukwaniritsa zofunikira zoyambira za injini. Komabe, ngati ntchito mosalekeza, injiniyo imatha kutentha kuwola chifukwa cha njira imodzi yosinthira kutentha. Madzi opopera madzi ozizira, mbali inayo, amakhala ndi nthawi yowonjezera yowonjezera chifukwa cha kuyambitsa kwamadzi atsopano a kutentha kwa kutentha. Ngakhale ngati injiniyo ikamayenda kwa nthawi yayitali, kutentha kwa injini sikudzakhala kokwera kwambiri, ndikupangitsa kukhala njira yabwino kwambiri yozizira kutentha.
1, wozungulira wa mpweya wa mpweya
1. Ubwino
Zero yolakwika yozizira (yozizira yachilengedwe) jenitors yozizira ya mpweya ili ndi mtengo wotsika komanso malo ochepa.
2. Zovuta
Chepetsani kutentha pang'ono ndi kuchepetsedwa ndi mtundu wa jeniselo, monga inliner ma injini, omwe samagwiritsa ntchito kuzirala kwa mpweya, kotero kuti kuzirala kwa mpweya sikungatheke kuti mitundu iwiri ya zitsulo.
Silinder wokhazikika wa mpweya udzapangidwa ndi kutentha kwakukulu kumangirira ndi mpweya. Ngati jenereta yopangidwa bwino yopangidwa bwino ya diesel yadzaza, palibe vuto konse. Ambiri aiwo amadziwika kuti ndi injini zokhala ndi mpweya ndipo ulibe masilinda wotsekedwa chifukwa cha kutentha kwambiri. Makina owiritsa aminesel ozizira ali ndi mtengo wotsika, ndipo bola ngati zasungidwa bwino, sipadzakhala vuto la kutentha kwambiri. M'malo mwake, mkhalidwe wamatsenga kwambiri mu injini zopota zamadzi ndizofala kwambiri. Mwachidule, kuzirala kwa mpweya kumakhala kokwanira kwa silinda imodzi yothamanga kwambiri, choncho palibe chifukwa chodera nkhawa za zovuta zakunja.
2, wotakasuka wa madzi aizi
1. Ubwino
Imatha kuwongolera bwino kutentha kwa mphamvu zambiri ndi kuthamanga kwa ma dizilo. Matenthedwe akakhala otsika, valavu ya injini yam'madzi imatsekedwa mpaka kutentha kwa mafuta kumakwera kuti akwaniritse mafuta abwino kwambiri. Matenthedwe akakhala okwera, valavu yansanja imatsegulira thanki yamadzi kuti iyambe kugwira ntchito. Matenthedwe akakhala okwera kwambiri, katswiri amayamba kuzizira kwa kutentha koyenera kwa jeneretal jeneretal. Uwu ndiye mfundo yokhazikika ya opaleshoni yolimba.
2. Zovuta
Mtengo wokwera, kapangidwe kake, komanso chilema cholepheretsa kwambiri chifukwa cha malo akulu omwe amakhala ndi thanki yamadzi yakunja.
Madzi ozizira a dielosel ndi njira yozizira yozizira kutentha. Mfundo yozizira madzi ndikuziziritsa cylinder chovala ndi mutu pokutira ndi madzi oyenda. Zigawo zikuluzikulu zamadzi zozizira ndi pampu yamadzi, kutentha kwamadzi kwa thanki, komanso zokupiza. Kuzizira kwamadzi ndi njira yofunikira yozizira yozizira kwa cylinder yambiri, mphamvu yayikulu, komanso mafuta othamanga kwambiri (ndi mafuta am'madzi awiri ozizira). Ma injini ang'onoang'ono omwe sakuthana ndi ma siloji nthawi zambiri samafuna kuziziritsa madzi ndipo sangathe kupanga kutentha kwambiri.
3, Mafuta atachira mu seesel
1. Ubwino
Kuzizira kumawonekeratu, ndipo kulephera kuli kochepa. Kutentha kwamafuta kochepa kumachepetsa kutentha kwapamwamba kwa mafuta.
2. Zovuta
Pali zoletsa pa kuchuluka kwa mafuta omwe amafunikira kuti asunthe. Ma radiator a mafuta sayenera kukhala akulu kwambiri. Ngati mafuta ndi akulu kwambiri, imayenda mu radiator yamafuta, ndikupangitsa mafuta okwanira pansi pa jeneretal jeneretal.
Kuzizira kwa mafuta kumagwiritsa ntchito mafuta ake injini kuti athe kutentha kudzera mu radiator yamafuta (mafuta a radiator ndi thankiyo ndi imodzi yokha, imodzi yokha yokhala ndi madzi). Chifukwa chakuti malire ozungulira mafuta amachokera pampu mafuta a jeneretal jensel, mafuta ozizira amangofuna chotenthetsera mafuta (thanki yamafuta). Mafuta ozizira ozizira amakhala ndi fan ndi valavu ya throttle. Dongosolo lozizira lozizira nthawi zambiri limakhala ndi makina amitundu ya arcade osiyanasiyana, kufunafuna bata komanso zolimbitsa mphamvu. Makina amodzi okhala ndi ma cylinder ozizira ali oyenera kusintha makina ozizira ozizira, ndikusintha kuchokera ku makina ozizira ozizira ozizira amangofunika kuwonjezera mafuta am'madzi pakati pa gawo la mafuta.
4, kutchula zabwino ndi zovuta
1. Kusiyana pakati pa Kuzizira kwa mafuta ndi kuzizira madzi
Choyamba, kutentha kwa kutentha kwa ma radiator kuli kovuta kwambiri, pomwe kutentha kwa madzi kumazizira kwambiri. Mafuta okhazikika ma radia nthawi zambiri amakhala ochepa kwambiri kukula, pomwe ma radiators ozizira amadzaza thupi. Ngati makina anu ali ndi mitundu yonse ya ma radiators, ndiye wamkulu ndi radiator yolimba yamadzi. Kusiyana kwinanso ndichakuti ma radia otakatamazidwa m'magazi ali ndi mafani amagetsi kumbuyo kwawo, pomwe ma radia ozizira samagwiritsidwa ntchito kawirikawiri (ngakhale zigawo zina za stroke sizimagwiritsa ntchito mafani a radiator).
2. Ubwino ndi zovuta
(1) Mafuta ozizira:
Wozizira wamafuta amakhala ndi radiator ofanana ndi radiator yophika yamadzi, yomwe imazungulira mafuta mkati mwa neesel kuti muchepetse kutentha. Kuyerekeza ndi wozizira wamadzi, kapangidwe kake kamakhalanso kosavuta. Chifukwa chozizira kwambiri kwa mafuta omwe amapatsirana zigawo za jenesel jenel, zotsatirapo zotentha zimakhalanso bwino, zomwe zili bwino kuposa mtundu wokhazikika, koma osati monga wozizira wamadzi.
(2) Wozizira madzi:
Kapangidwe ka makina ozizira-kozizira kumakhala kovuta, ndipo mutu wa silinda, mutu wa nelliser, ndipo ngakhale mapampu owoneka bwino (akasinja am'madzi, masitani, madzi Mapaipi, kutentha, etc. Mtengo wake ndiwokwera kwambiri, ndipo voliyumu ndiyokulirapo. Komabe, ili ndi zotsatira zabwino kwambiri komanso kuzizirira yunifolomu. Ubwino wa Injini Yokongoletsedwa ndi madzi ndikuti imatha kutentha msanga, amatha kuthamanga pa liwiro lalitali kwa nthawi yayitali, ndipo sakonda kutentha. Komabe, zovuta ndichakuti injini yozizira ndi madzi ali ndi mawonekedwe ovuta, ndipo ngati masitepe am'mimba pakapita nthawi, amakonda kutsanulira. Ngati zozizira zozizira kumidzi, zimapangitsa kuti galimotoyo igwe pansi, ndikuyika ngozi ina yobisika. Komabe, zonse, ubwino umaposa zovuta zina.
(3) Mpweya wozizira:
Kapangidwe ka injini yozizira kwa mpweya kumawonekera makamaka pakuwonekera kwa injini. Injiniyi sikuti ali ndi phukusi lililonse, ndipo bola liyambike, padzakhala mphesa. Mpweya wozizira umayenda kudzera mumiyala yotentha yazachigawo cha injini, ndikuwotcha mpweya ndikuchotsa kutentha kwina. Kuzungulira kumeneku kumatha kusungira kutentha kwa injini mkati mwazinthu zofunikira.
Chidule:
Ma injini ozizira ndi injini zokhala ndi mpweya ndi kufotokoza kwa njira zozizira zozizira, chifukwa mitundu iwiri iyi ya mitundu iyi imagwiritsa ntchito mitundu yosiyanasiyana ya kutentha kwa ntchito. Komabe, mitundu yonse ya injini zimagwirizanitsa mphepo yachilengedwe yopangira kutentha, kupatula injini zopota zamadzi kumakhala ndi kutentha kwambiri. Nthawi zambiri, injini zokhala ndi madzi zimatha kusiyanitsa kutentha komwe kumapangidwa mwachangu ndi ntchito yonse yogwirira ntchito pogwiritsa ntchito madzi owonjezera pakuwotcha kutentha. Komabe, injini zokhala ndi mpweya ndi zotsika kwambiri chifukwa chosowa makina ozizira ozizira, koma mawonekedwe awo ndiophweka. Malingana ngati kuyeretsa mutu wa silinda ndi cylinder block kumasungidwa, dongosolo lawo lozizira silikhala ndi zolakwa zilizonse. Komabe, ma injini opota amadzi amafunikira mapampu owonjezera madzi, ma radiator, ozizira, etc.
