Makina ozizira a injini ndi imodzi mwazinthu zisanu ndi chimodzi zazikulu za injini.Ntchito yake ndikutaya gawo la kutentha komwe kumatengedwa ndi zigawo zotenthedwa mu nthawi kuti zitsimikizire kuti injini ikugwira ntchito pa kutentha koyenera kwambiri.
Zigawo za dongosolo yozizira
Pazigawo zonse zoziziritsa kuzizira, sing'anga yozizira imakhala yoziziritsa, ndipo zigawo zazikuluzikulu ndi thermostat, mpope wamadzi, lamba wapampope wamadzi, radiator, fan yoziziritsa, sensa ya kutentha kwamadzi, thanki yosungira madzi, ndi chipangizo chotenthetsera (chofanana ndi radiator).
1) Zoziziritsa
Coolant, yomwe imadziwikanso kuti antifreeze, ndi madzi opangidwa ndi zowonjezera zoletsa kuzizira, zowonjezera kuti zitsulo zisawonongeke, ndi madzi.Iyenera kukhala ndi anti-freeze, anti-corrosion, conductivity yamafuta ndi zinthu zosawonongeka.Masiku ano, ethylene glycol imagwiritsidwa ntchito nthawi zambiri ngati chigawo chachikulu, ndipo antifreeze yokhala ndi anti-corrosion zowonjezera ndi madzi amawonjezeredwa.Madzi ozizira makamaka ndi madzi ofewa, omwe angalepheretse jekete lamadzi la injini kuti lisapangike, zomwe zingatseke kutengera kutentha ndikupangitsa injini kutenthedwa.Kuonjezera antifreeze m'madzi kumakwezanso kuwira kwa choziziritsa, chomwe chimakhala ndi mphamvu yoletsa kuwira msanga kwa choziziritsa.Kuphatikiza apo, choziziritsa kukhosi chimakhalanso ndi zoletsa thovu, zomwe zimatha kuletsa mpweya kuti usatulutse thovu chifukwa cha chipwirikiti cha mpope wamadzi ndikuletsa khoma la jekete lamadzi kuti lisathe kutentha.
2) Thermostat
Kuyambira poyambitsa kuzizira, zitha kuwoneka ngati chotenthetsera chasankha kupita "cold cycle" kapena "normal cycle".Thermostat imatsegulidwa pambuyo pa 80 ° C, ndipo kutsegulira kwakukulu kumakhala pa 95 ° C.Kulephera kutseka chotenthetsera kumapangitsa kuti kuzungulirako kukhale "mkombero wamba" kuyambira pachiyambi, zomwe zidzachititsa kuti injini isafike kapena kufika kutentha kwabwino mwamsanga.Thermostat sichingatsegulidwe kapena kutseguka kumakhala kosasunthika, zomwe zingalepheretse choziziritsa kuzizira kudzera pa radiator, zomwe zimapangitsa kuti kutentha kukhale kokwera kwambiri, kapena kukhala kwabwinobwino kukakhala kokwera.Ngati kutentha kwambiri kumachitika chifukwa chotenthetsera sichingatsegulidwe, kutentha ndi kupanikizika kwa mapaipi apamwamba ndi apansi a radiator adzakhala osiyana.
3) Pampu yamadzi
Ntchito ya mpope wamadzi ndi kukakamiza choziziritsa kukhosi kuti chizizungulira mu njira yozizirira.Kulephera kwa mpope wamadzi nthawi zambiri kumayamba chifukwa cha kuwonongeka kwa chisindikizo chamadzi chomwe chimayambitsa kutayikira, ndipo kulephera kwa chonyamula kumayambitsa kusinthasintha kwachilendo kapena phokoso.Injini ikatenthedwa, chinthu choyamba muyenera kulabadira ndi lamba wa mpope wamadzi, fufuzani ngati lambayo wathyoka kapena kumasuka.
4) Radiator
Injini ikugwira ntchito, choziziritsa kukhosi chimayenda pakati pa radiator, mpweya umadutsa kunja kwapakati pa radiator, ndipo choziziritsa chotentha chimakhala chozizira chifukwa cha kutentha kwa mpweya.Palinso gawo laling'ono lofunikira pa radiator, kapu ya radiator, yomwe imanyalanyazidwa mosavuta.Pamene kutentha kumasintha, choziziritsa kuzizira "chidzakula ndi kugwirizanitsa", ndipo mphamvu yamkati ya radiator imawonjezeka chifukwa cha kufalikira kwa choziziritsira.Pamene mphamvu ya mkati ifika pamlingo wina, chivundikiro cha radiator chimatsegula ndipo choziziritsa chimalowa mu thanki yosungirako;m'munsi ndipo choziziriracho chimabwerera ku radiator.Ngati choziziritsa mu accumulator sichichepa, koma mulingo wamadzimadzi wa radiator umachepa, ndiye kapu ya radiator sikugwira ntchito!
5) Kuzizira fan
Panthawi yoyendetsa bwino, mpweya wothamanga kwambiri ndi wokwanira kuti usungunuke kutentha, ndipo fan nthawi zambiri sagwira ntchito panthawiyi;koma pothamanga pang'onopang'ono komanso m'malo mwake, chotenthetsera chikhoza kuzungulira kuthandiza radiator kuchotsa kutentha.Kuyamba kwa fan kumayendetsedwa ndi sensa ya kutentha kwa madzi.
6) Sensa ya kutentha kwa madzi
Sensa ya kutentha kwa madzi kwenikweni ndi kusintha kwa kutentha.Pamene kutentha kwa madzi olowetsa injini kupitirira 90 ° C, sensa ya kutentha kwa madzi imagwirizanitsa ndi dera la fan.Ngati kuzungulira kuli kwabwinobwino ndipo faniyo sichimazungulira kutentha kumakwera, sensa ya kutentha kwa madzi ndi faniyo iyenera kufufuzidwa.
7) Tanki yosungiramo madzi
Ntchito ya thanki yosungiramo madzi ndikuwonjezera choziziritsira ndikuteteza kusintha kwa "kukulitsa kwamafuta ndi kuzizira kozizira", kotero musadzaze madziwo mochulukira.Ngati thanki yosungiramo madzi ilibe kanthu, simungangowonjezera madzi mu thanki, muyenera kutsegula kapu ya radiator kuti muwone mlingo wamadzimadzi ndikuwonjezera ozizira, apo ayi thanki yosungiramo madzi idzataya ntchito yake.
8) Kutentha chipangizo
Chida chotenthetsera mgalimoto nthawi zambiri sichikhala vuto.Zitha kuwoneka kuchokera kumayendedwe oyambira kuti kuzungulira uku sikuyendetsedwa ndi thermostat, kotero kuyatsa chotenthetsera galimoto ikazizira, kuzungulira kumeneku kudzakhala ndi zotsatira zochedwa pang'ono pakukwera kwa kutentha kwa injini, koma zotsatira zake zimakhaladi. yaying'ono, kotero palibe chifukwa chotenthetsera injini.Kuzizira.Ndi chifukwa cha mawonekedwe a kuzungulira uku kuti pakachitika ngozi pamene injini ikuwotcha, kutsegula mazenera ndikuyatsa kutentha kwambiri kumathandizira kuziziritsa injini kumlingo wina.
