Umwanya wakazi nihame ryumufana ukonjesha imodoka
1.
2. Umuzunguruko wumufana uhujwe binyuze mumurongo wabafana, hanyuma moteri yabafana iratangira.
3. Iyo sensor yubushyuhe bwikigega cyamazi ibonye ko ubushyuhe bwikigega cyamazi buri munsi yumuryango, icyerekezo cyabafana kiratandukana kandi moteri yumuyaga ihagarika gukora.
Ikintu kijyanye nigikorwa cyabafana nubushyuhe bwikigega, kandi ubushyuhe bwikigega ntaho buhuriye nubushyuhe bwamazi ya moteri.
Umwanya wakazi nihame ryumufana ukonjesha ibinyabiziga: sisitemu yo gukonjesha imodoka ikubiyemo ubwoko bubiri.
Gukonjesha amazi no gukonjesha ikirere. Sisitemu yo gukonjesha ikinyabiziga gikonjesha kizenguruka amazi binyuze mumiyoboro n'imiyoboro muri moteri. Iyo amazi atembera muri moteri ishyushye, ikurura ubushyuhe kandi ikonjesha moteri. Amazi amaze guca muri moteri, yoherezwa mu guhinduranya ubushyuhe (cyangwa radiator), aho ubushyuhe buva mumazi bukwirakwizwa mu kirere. Gukonjesha ikirere Imodoka zimwe zo hambere zakoresheje tekinoroji yo gukonjesha ikirere, ariko imodoka zigezweho ntizikoresha ubu buryo. Aho kuzenguruka amazi binyuze muri moteri, ubu buryo bwo gukonjesha bukoresha amabati ya aluminiyumu yometse hejuru ya silinderi ya moteri kugirango akonje. Abafana bakomeye bahuha umwuka mumabati ya aluminium, bagabura ubushyuhe mukirere cyubusa, gikonjesha moteri. Kuberako imodoka nyinshi zikoresha gukonjesha, imodoka zidafite imiyoboro myinshi muri sisitemu yo gukonjesha.
Pompe imaze kugeza amazi kumurongo wa moteri, amazi atangira kunyura mumiyoboro ya moteri ikikije silinderi. Amazi noneho asubira muri thermostat binyuze mumutwe wa moteri ya moteri, aho isohoka muri moteri. Niba thermostat yazimye, amazi azasubira muri pompe binyuze mumiyoboro ikikije thermostat. Niba thermostat ifunguye, amazi azatangira gutembera mumirasire hanyuma asubire muri pompe.
Sisitemu yo gushyushya nayo ifite inzinguzingo zitandukanye. Umuzenguruko utangirira mumutwe wa silinderi kandi ugaburira amazi binyuze mumashanyarazi mbere yo gusubira kuri pompe. Ku modoka zifite itumanaho ryikora, mubisanzwe hariho inzira yihariye yo gukonjesha amavuta yohereza yubatswe mumirasire. Amavuta yoherezwa avomwa no guhererekanya binyuze muyindi mashanyarazi ihinduranya. Amazi arashobora gukora mubushuhe bugari kuva munsi ya dogere selisiyusi gushika hejuru ya dogere selisiyusi 38.
Kubwibyo, amazi yose yakoreshejwe mugukonjesha moteri igomba kuba ifite ubukonje buke cyane, ahantu hejuru cyane, kandi ikabasha gukuramo ubushyuhe bwinshi. Amazi nimwe mumazi akora neza kugirango akuremo ubushyuhe, ariko aho amazi akonjesha ni menshi cyane kuburyo atujuje ibyangombwa bya moteri yimodoka. Amazi amamodoka menshi akoresha ni uruvange rwamazi na Ethylene glycol (c2h6o2), bizwi kandi nka coolant. Mugushyiramo Ethylene glycol mumazi, aho guteka birashobora kwiyongera cyane kandi aho gukonja bigabanuka.
Igihe cyose moteri ikora, pompe izenguruka amazi. Kimwe na pompe ya centrifugal ikoreshwa mumodoka, nkuko pompe izunguruka, isunika amazi hanze nimbaraga za centrifugal kandi igahora iyinyunyuza hagati. Kwinjira kwa pompe biherereye hafi yikigo kugirango amazi agarutse avuye mumirasire ashobora kuvugana nicyuma cya pompe. Icyuma cya pompe gitwara amazi hanze ya pompe, aho yinjira muri moteri. Amazi ava muri pompe atangira kunyura muri moteri yumutwe no mumutwe, hanyuma yinjira mumirasire, hanyuma asubira muri pompe. Moteri ya silinderi ya moteri hamwe numutwe bifite imiyoboro myinshi ikozwe muri casting cyangwa imashini kugirango byorohereze amazi.
Niba amazi yo muri iyo miyoboro atemba neza, gusa amazi ahuye numuyoboro azahita akonjeshwa. Ubushyuhe bwimuwe buva mumazi anyura mumiyoboro yerekeza kumuyoboro biterwa nubushyuhe bwubushyuhe buri hagati yumuyoboro namazi akora kumuyoboro. Kubwibyo, niba amazi ahuye numuyoboro akonje vuba, ubushyuhe bwimuwe buzaba buto. Amazi yose ari mu muyoboro arashobora gukoreshwa neza muguteza imivurungano mu muyoboro, kuvanga amazi yose, no gutuma ayo mazi ahura numuyoboro mubushyuhe bwinshi kugirango ushushe ubushyuhe bwinshi.
Imashini ikwirakwiza isa cyane na radiatori muri radiatori, usibye ko amavuta adahindura ubushyuhe numubiri wikirere, ahubwo na antifreeze mumirasire. Igifuniko cy'igitutu cy'igitutu gishobora kongera igitutu cya antifreeze kuri 25 ℃.
Igikorwa cyingenzi cya thermostat ni ugushyushya moteri vuba no gukomeza ubushyuhe buhoraho. Ibi bigerwaho muguhindura urugero rwamazi atembera mumirasire. Ku bushyuhe buke, imiyoboro ya radiator izahagarikwa rwose, bivuze ko antifreeze yose izenguruka binyuze kuri moteri. Ubushyuhe bwa antifreeze nibumara kuzamuka kuri 82-91 C, thermostat izakingurwa, izemerera amazi gutembera mumirasire. Iyo ubushyuhe bwa antifreeze bugeze kuri 93-103 ℃, umugenzuzi wubushyuhe azahora.
Umuyaga ukonje usa na thermostat, ugomba rero guhindurwa kugirango moteri igumane ubushyuhe buhoraho. Imodoka zitwara ibiziga byimbere bifite abafana b'amashanyarazi kuko ubusanzwe moteri iba itambitse, bivuze ko umusaruro wa moteri ureba kuruhande rwimodoka.
Umufana arashobora guhindurwa na sisitemu ya thermostatike cyangwa mudasobwa ya moteri. Iyo ubushyuhe buzamutse hejuru yashyizweho, aba bafana bazafungura. Iyo ubushyuhe bugabanutse munsi yagenwe, aba bafana bazimya. Ubukonje bukonje Imodoka yinyuma yimodoka ifite moteri ndende isanzwe iba ifite ibyuma bikonjesha bikonjesha. Aba bafana bafite climatike ya thermostatike. Clutch iherereye hagati yabafana, ikikijwe numuyaga uva mumirasire. Iyi clcc viscous clutch rimwe na rimwe irasa cyane na viscous coupler yimodoka yimodoka yose. Iyo imodoka ishyushye, fungura Windows yose hanyuma ukoreshe ubushyuhe mugihe umufana arimo yihuta. Ni ukubera ko sisitemu yo gushyushya mubyukuri aribwo buryo bwa kabiri bwo gukonjesha, bushobora kwerekana imiterere ya sisitemu nyamukuru yo gukonjesha ku modoka.
Sisitemu yo gushyushya inzogera zishyushye ziri ku kibaho cyimodoka mubyukuri ni radiator nto. Umuyaga ushyushya wohereza umwuka wubusa unyuze mu cyuma gishyushya no mu cyumba cy’abagenzi cyimodoka. Inzogera zishyushya zisa na radiator nto. Umuhengeri ushyushya antifreeze yumuriro uva mumutwe wa silinderi hanyuma ukawusubiza muri pompe kugirango umushyushya ushobora gukora mugihe thermostat ifunguye cyangwa yazimye.
