Kodi thermostat ndi chiyani?

Thermostat ndi imodzi mwazinthu zoziziritsa makina. Chida ichi chimakuthandizani kuti muzisunga kutentha kwa mota pomwe ikuyenda.

Ganizirani ntchito yomwe thermostat imagwira, kapangidwe kake, ndi zovuta zina zomwe zingachitike.

Ndi chiyani?

Mwachidule, thermostat ndi valavu yomwe imagwira ntchito pakusintha kwa kutentha kwachilengedwe komwe ikupezeka. Pankhani yozizira yamagalimoto, chipangizochi chimayikidwa pa mphanda wa ma payipi awiri. Mmodzi amapanga zomwe zimatchedwa bwalo laling'ono lazoyenda, ndipo zinazo - zazikulu.

Kodi thermostat ndi chiyani?

Aliyense akudziwa kuti injini amatentha kwambiri pa ntchito. Kuti isalephere kutenthedwa kwambiri, ili ndi jekete lozizira, lomwe limalumikizidwa ndi mapaipi kupita ku radiator.

Chifukwa cha kuyimitsidwa kwamagalimoto, mafuta onse amapita poto wamafuta pang'onopang'ono. Likukhalira kuti injini ozizira pafupifupi palibe mafuta. Popeza izi, injini yoyaka mkati ikayamba, sayenera kupatsidwa katundu wolemera kuti ziwalo zake zisathe msanga kuposa masiku onse.

Mafuta ozizira omwe ali mchimake amakhala owoneka bwino kwambiri kuposa momwe magetsi amagwirira ntchito, chifukwa chake zimakhala zovuta kwambiri kuti pampu iwapope mgawo lonse. Kuti ichitike mwachangu, injini iyenera kufikira kutentha kwa opaleshoni mwachangu momwe zingathere. Kenako mafuta amayamba kukhala amadzimadzi ndipo ziwalozo zimapaka mafuta mwachangu.

Opanga magalimoto oyamba adakumana ndi ntchito yovuta: chochita kuti injini ifundire mwachangu, koma kutentha kwake kumakhala kolimba panthawi yogwira ntchito? Pachifukwa ichi, makina ozizira anali amakono, ndipo munali ma circuits awiri oyenda. Imodzi imapereka kutentha kwachangu kwa magawo onse a injini (zoletsa kuwuma kapena zoletsa kuwotcha zimatenthedwa kuchokera pamakoma otentha a zonenepa ndikusamutsa kutentha kwa thupi lonse la injini yoyaka mkati). Chachiwiri chimagwiritsidwa ntchito kuziziritsa chipangizocho chikamafika kutentha kwa magwiridwe antchito.

Thermostat m'dongosolo lino imagwira ntchito ya valavu, yomwe imatseketsa Kutentha kwa injini panthawi yoyenera ndikulumikiza radiator kuti isunge kutentha kwa injini yoyaka mkati. Kodi izi zimatheka bwanji?

Kodi thermostat ili pati mgalimoto?

M'mitundu yambiri, auto thermostat imawoneka yofanana, kupatulapo mawonekedwe ena. Thermostat idzayima pa mphambano ya mapaipi amachokera ku injini ndi radiator yozizira. Zinthu izi zidzalumikizidwa ndi nyumba ya thermostat. Ngati makinawa alibe nyumba, ndiye amaikidwa mu jekete la injini (nyumba ya silinda).

Mosasamala kanthu za malo a thermostat, chitoliro chimodzi chozizira chopita ku radiator chidzachoka pamenepo.

Chipangizo ndi njira yogwiritsira ntchito imodzi

Kupanga kwa thermostat kumaphatikizapo:

• Cylinder Kwenikweni, thupi lake limapangidwa ndi mkuwa. Chitsulo ichi chimakhala ndi matenthedwe abwino.
• Pali zowonjezera mkati mwake. Kutengera mtundu wa gawolo, limatha kupangidwa ndi madzi ndi mowa, kapena limakhala la sera losakanizika ndi ufa wamkuwa, aluminium ndi graphite. Nkhaniyi ili ndi koyefishienti yayikulu pakukula kwamatenthedwe. Malingana ngati sera ikuzizira, ndizovuta. Ikukulira pamene ikutentha.
• Tsinde lazitsulo. Imaikidwa mkati mwa silinda.
• Mphira kompresa. Izi zimalepheretsa kuti cholowacho chisalowe chozizira ndikusunthira tsinde.
• Valavu. Pali zinthu ziwirizi pachidacho - chimodzi pamwamba pa imodzi, imodzi pansi (mu mitundu ina ndi imodzi). Amatsegula / kutseka dera laling'ono komanso lalikulu.
• Nyumba. Onse mavavu ndi yamphamvu ali atakhazikika pa izo.
• Akasupe amapereka kukana kofunikira pakuyenda.

Dongosolo lonse limayikidwa mkati molumikizana pakati pa bwalo laling'ono ndi lalikulu. Kumbali imodzi, cholowera chaching'ono chimalumikizidwa ndi chipindacho, mbali inayo, polowera kwakukulu. Pali njira imodzi yokha yotulukira foloko.

Pamene chozizira chimazungulira mozungulira kochepa, pang'onopang'ono chimatenthetsa silinda wa thermostat. Pang'ono ndi pang'ono kutentha kwa chilengedwe kumakwera. Chizindikirocho chikamafika madigiri 75 mpaka 95, sera yasungunuka kale (granules yachitsulo imathandizira izi) ndikuyamba kukulira. Popeza ilibe malo m'mimbamo, imakanikizana ndi chidindo cha mphira.

Gawo lamagetsi likatenthetsa mokwanira, valavu yayikulu yayikulu imayamba kutsegula, ndipo antifreeze (kapena antifreeze) imayamba kuyenda mozungulira modutsa mu radiator. Popeza kugwira ntchito kwa tsinde kumadalira kutentha kwa madzi munjirayo, chipangizocho chimakulolani kuti muzisunga kutentha kwamagalimoto nthawi iliyonse mchaka: chilimwe sichimalola kutenthedwa, ndipo nthawi yachisanu imafika pachangu pantchito yotentha.

Ziribe kanthu za kusintha kwa thermostat, zonse zimagwira ntchito mofanana. Kusiyana kokha pakati pawo ndi kutentha komwe kumayambira valavu. Chizindikiro ichi chimadalira mtundu wa injini (iliyonse ili ndi kutentha kwake kogwira ntchito, chifukwa chake, valavu iyeneranso kutsegula mkati mwazomwe zanenedwa).

Kutengera dera lomwe galimoto imayendetsedwera, thermostat iyeneranso kusankhidwa. Ngati gawo lalikulu la chaka ndilotentha mokwanira, ndiye kuti kuyenera kuyikidwa thermostat yomwe imagwira ntchito kutsika pang'ono. M'malo ozizira ozizira, m'malo mwake, kuti injini izitha kutentha bwino.

Pofuna kuti woyendetsa galimotoyo asakhazikitse gawo losayenera, wopanga akuwonetsa gawo lotsegulira valavu pathupi la chipangizocho.

Kuphatikiza apo, ma thermostats onse ndiosiyana:

• Chiwerengero cha mavavu. Mapangidwe osavuta ali ndi valavu imodzi. Zosinthazi zimagwiritsidwa ntchito mgalimoto zakale. Magalimoto ambiri amakono amagwiritsa ntchito ma valve awiri. Mukusintha kotere, ma valve amakhala okhazikika pa tsinde limodzi, lomwe limatsimikizira kuyenda kwawo.
• Gawo limodzi ndi awiri. Mitundu yama sitepe amodzi imagwiritsidwa ntchito pamakina ozizira achikale. Ngati madzi amadzimadzi amayenda mopanikizika, ndiye kuti magawo awiri ama thermostats amaikidwa. Mu zitsanzo zotere, valavu imakhala ndi zinthu ziwiri. Chimodzi mwazomwe zimayambitsidwa ndikamayesetsa kuthana ndi zovuta, kenako chachiwiri chimayambitsidwa.
• Ndi wopanda thupi. Mitundu yambiri imakhala yopanda tanthauzo. Kuti mubwezeretse, muyenera kusokoneza msonkhano womwe waikidwa. Kuwongolera ntchitoyi, opanga amapanga zosintha zina zomwe zasonkhanitsidwa kale pamalopo. Ndikokwanira kulumikiza kulumikizana kofananira.
• Kutenthedwa. Magalimoto ena amakhala ndi ma thermostats okhala ndi kachipangizo kotentha komanso makina otenthetsera silinda. Zipangizo zoterezi zimayang'aniridwa ndi ECU. Ntchito yayikulu yazida zotere ndikusintha kutentha kwa ma valve. Ngati galimoto ikuyenda popanda katundu wolemera, thermostat ikugwira bwino ntchito. Ngati pali katundu wowonjezera pachipindacho, magetsi amakakamiza kuti valavu itsegule koyambirira (kutentha kozizira kumakhala pafupifupi madigiri 10 kutsika). Kusintha kumeneku kumapulumutsa mafuta.
• Miyeso. Njira iliyonse yozizira imagwiritsa ntchito mapaipi amitundumitundu osati kutalika kokha, komanso m'mimba mwake. Pogwirizana ndi parameter iyi, thermostat iyeneranso kusankhidwa, apo ayi antifreeze amayenda momasuka kuchokera kudera laling'ono kupita lalikulu komanso mosemphanitsa. Ngati kusinthidwa kwa thupi kudagulidwa, ndiye kuti m'mimba mwake mapaipi ndi mawonekedwe ake adzawonetsedwa.
• Zomaliza zonse. Izi ndizodalira ogulitsa. Ena ogulitsa amagulitsa zida zokhala ndi ma gaskets apamwamba, pomwe ena amaika zotsika zotsika, koma amapereka kugula analog yolimba.

Mitundu ndi mitundu ya ma thermostats

Pakati pa mitundu yonse ya ma thermostats pali:

1. Valovu imodzi;
2. magawo awiri;
3. Awiri valve;
4. Pakompyuta.

Kusiyana kwakukulu pakati pa zosinthidwazi kuli mu mfundo yotsegula ndi kuchuluka kwa ma valve. Mtundu wosavuta wa thermostat ndi valavu imodzi. Zitsanzo zambiri za kupanga zakunja zili ndi makina otere. Kugwira ntchito kwa thermostat kumachepetsedwa chifukwa chakuti valavu, pamene kutentha kwina kukufika, kumatsegula dera lalikulu la kuzungulira popanda kutseka dera laling'ono.

Ma thermostat a magawo awiri amagwiritsidwa ntchito m'makina omwe choziziritsa kuzizira chimakhala chopanikizika kwambiri. Mwamapangidwe, iyi ndi mtundu womwewo wa valve imodzi. Mbale wake uli ndi zinthu ziwiri za diameter zosiyana. Choyamba, mbale yaying'ono imayaka moto (chifukwa chazing'onoting'ono, imayenda mosavuta kuzungulira ndi kupanikizika kwakukulu), ndipo kumbuyo kwake bwalo limatsekedwa ndi mbale yaikulu. Chifukwa chake pamakina awa, bwalo lozizira la mota limatsegulidwa.

Kusintha kwa ma valve awiri a ma thermostats kumagwiritsidwa ntchito popanga makina ozizirira pamagalimoto apanyumba. Ma valve awiri amaikidwa pa actuator imodzi. Mmodzi ali ndi udindo pa ndondomeko ya bwalo lalikulu, ndipo winayo ndi wamng'ono. Kutengera malo oyendetsa, imodzi mwamabwalo ozungulira imatsekedwa.

Mu ma thermostats amagetsi, kuwonjezera pa chinthu chachikulu, chomwe chimatenthedwa ndi kutentha kwa choziziritsa kukhosi, chowotcha chowonjezera chimayikidwanso. Zimagwirizanitsa ndi unit control. Thermostat yotere imayang'aniridwa ndi ECU, yomwe imasankha njira yoyendetsera galimoto ndikusintha makina oziziritsa kumayendedwe awa.

Kuyang'ana imodzi mwagalimoto

Pali njira ziwiri zowunika thanzi la chipangizochi:

• Mwa kuchotsa dongosolo;
• Popanda kuchotsa m'galimoto.

Njira yoyamba imagwiritsidwa ntchito kawirikawiri. Ena amatembenukira kwa izo kuti atsimikize bwino momwe zimagwirira ntchito. Komanso, njirayi ikuthandizani kuti muwone momwe gawo latsopanoli likugwirira ntchito, chifukwa izi sizingachitike m'sitolo. Kuti muchite izi, muyenera kutenthetsa madzi (madzi otentha - pamwamba pa madigiri 90). Gawolo limaviikidwa mu chidebe chokhala ndi madzi otentha.

Ngati patapita mphindi zingapo valavu sitsegula, ndiye kuti gawolo ndi lolakwika - mwina chinachake chinachitika pa tsinde, kapena kasupe, kapena mwinamwake chinachake chinachitika ku chidebe chomwe sera ili. Pankhaniyi, thermostat iyenera kusinthidwa ndi yatsopano.

Kuti mumve zambiri zamomwe mungayang'anire gawo latsopano, onani kanema:

Kuyang'ana galimoto imodzi

Momwe mungadziwire ngati imagwira ntchito kapena ayi?

Simusowa kukhala katswiri wodziwa zamakina kuti muwone momwe thermostat imagwirira ntchito osachotsa pamakinawo. Ndikokwanira kumvetsetsa momwe chipangizocho chimagwirira ntchito. M'nthawi yoyamba ya injini, makina onse ozizira sayenera kutentha. Poganizira izi, muyenera kuchita izi:

1. Yambitsani injini kuti iziyenda.
2. Pakadali pano, muyenera kuyesa mapaipi olumikizidwa ndi radiator. Ngati imodzi ndiyabwino, makinawo satha kutentha mpaka mphindi zisanu (kutengera kutentha kozungulira). Dongosolo lozizira limasonyeza kuti valavu watsekedwa.
3. Kenako, timayang'ana muvi womwe uli padashboard. Ngati ikukwera mwachangu ndikupita kupitirira 90-degree, yesaninso mapaipi. Makina ozizira akuwonetsa kuti valavu sikukuyankha.
4. Momwemo, zotsatirazi zikuyenera kuchitika: injini ikayamba kutentha, kuzirala kumazizira. Ikangofika kutentha komwe ikufunidwa, valavu imatseguka ndipo antifreeze amayenda mozungulira dera lalikulu. Izi amaziziritsa kulambalala pang'onopang'ono.

Ngati pali zolakwika mu ntchito ya thermostat, ndibwino kuti musinthe nthawi yomweyo.

Thermostat yotentha komanso yozizira. Kutsegula kutentha

Mukasintha thermostat, tikulimbikitsidwa kugula chofanana ndi fakitale. Imatsegula pa kutentha kozizira kwa madigiri 82 mpaka 88. Koma nthawi zina, thermostat yosakhala yokhazikika ndiyothandiza.

Mwachitsanzo, pali ma thermostats "ozizira" ndi "otentha". Zida zamtundu woyamba zimatsegulidwa pa kutentha pafupifupi madigiri 76-78. Chachiwiri chimagwira ntchito ngati choziziritsa chikatentha mpaka pafupifupi madigiri 95.

Thermostat yozizira ikhoza kuikidwa m'malo mwa yokhazikika m'galimoto yomwe injini yake imatentha mofulumira kwambiri ndipo nthawi zambiri imafika powira. Zoonadi, kusinthidwa kotereku kwa dongosolo lozizira sikungathetse vuto la galimoto, koma injini yosatenthetsera bwino idzawira patapita nthawi.

ngati galimotoyo ikugwiritsidwa ntchito kumpoto, ndiye kuti oyendetsa galimoto amasintha makina oziziritsa kumtunda wa kutentha kwapamwamba kwa thermostat. Ndi kukhazikitsa kwa "hot" version, injini yoziziritsa injini sichidzawotcha injini yoyaka mkati, yomwe idzakhudze ntchito ya chitofu.

Kodi mitundu yazovuta ndi iti?

Popeza chotenthetsera chimayenera kuyankha nthawi zonse pakasintha kwa kutentha kwa injini yozizirira, chiyenera kugwira ntchito. Taganizirani zovuta zazikulu za thermostat mu dongosolo lozizira. Ndipotu, pali awiri a iwo: otsekedwa mu malo otsekedwa kapena otseguka.

Zokhala motsekedwa kwathunthu

Ngati chotenthetsera chisiya kutseguka, choziziritsiracho chimangozungulira mozungulira pang'ono pomwe injini ikuyenda. Izi zikutanthauza kuti injini idzatenthetsa bwino.

Koma chifukwa chakuti injini yoyaka mkati yomwe yafika kutentha kwake sikulandira kuziziritsa koyenera (antifreeze sichimazungulira bwalo lalikulu, zomwe zikutanthauza kuti sizizizira mu rediyeta), idzafika mofulumira kwambiri. chizindikiro cha kutentha. Komanso, injini yoyaka mkati imatha kuwira, ngakhale kunja kukuzizira. Kuti athetse vuto limeneli, m'pofunika kusintha thermostat ndi latsopano.

 "Kukhazikika" pamalo otseguka kwathunthu kapena pang'ono

Pankhaniyi, zoziziritsa kukhosi mu dongosolo kuyambira chiyambi cha injini yomweyo akuyamba kuzungulira mu bwalo lalikulu. Kuti injini yoyaka mkati ifike kutentha kwa ntchito (chifukwa cha izi, mafuta a injini amatenthetsa bwino ndikuyika magawo onse a unit ndi apamwamba), zimatenga nthawi yochulukirapo.

Ngati thermostat ikulephera m'nyengo yozizira, ndiye kuti kuzizira injiniyo imatentha kwambiri. Ngati izi siziri vuto linalake m'chilimwe, ndiye kuti m'nyengo yozizira sikungatheke kutentha m'galimoto yotere (radiator ya stove idzakhala yozizira).

Kodi mutha kuyendetsa popanda chotenthetsera?

Lingaliro lofananalo limayendera eni magalimoto omwe m'chilimwe nthawi zonse amakumana ndi kutentha kwagalimoto. Amangochotsa thermostat m'dongosolo, ndipo injini ikayamba, antifreeze nthawi yomweyo imapita mubwalo lalikulu. Ngakhale izi sizimalepheretsa injiniyo nthawi yomweyo, siziyenera kuchita izi (zinali zopanda pake zomwe akatswiri adabwera ndikuyika chinthu ichi m'galimoto).

Chifukwa chake ndi chakuti thermostat m'galimoto ndiyofunikira kuti akhazikitse ulamuliro wa kutentha kwagalimoto. Sizimangopereka kutentha kapena kuziziritsa kwa magetsi. Ngati chinthu ichi chichotsedwa ku dongosolo lozizira, ndiye kuti mwiniwake wa galimoto amazimitsa injini yoyaka moto mkati. Koma thermostat yotseguka sikuti imangotembenuza kuzungulira kwakukulu.

Nthawi yomweyo, imalepheretsa kuzungulira kwazing'ono. Ngati muchotsa chotenthetsera, ndiye, malingana ndi mtundu wa kuzizira, pampu idzakakamiza antifreeze nthawi yomweyo mu bwalo laling'ono, ngakhale thermostat itachotsedwa mu dongosolo. Chifukwa chake ndikuti kufalikira kumatsata njira yochepetsera kukana. Chifukwa chake, pofuna kuthetsa kutenthedwa kwa mota, woyendetsa amatha kukonza kutenthedwa kwanuko m'dongosolo.

Koma injini yosatenthedwa bwino imatha kuvutikira kuposa kutenthedwa. Mu injini yozizira (ndipo pozungulira nthawi yomweyo mu bwalo lalikulu, kutentha kwake sikungafike ngakhale madigiri 70), kusakaniza kwa mpweya wa mpweya sikutentha bwino, zomwe zimapangitsa kuti mwaye aziwoneka mmenemo, spark plugs kapena mapulagi owala adzalephera. mofulumira, lambda adzavutika.

Ndi bwino kuti musachotse thermostat ndi kutenthedwa pafupipafupi kwa injini, koma kukhazikitsa analogue yozizira (kutsegula koyambirira). Muyeneranso kudziwa chifukwa chake injini imatenthedwa nthawi zambiri. Chifukwa chake chikhoza kukhala radiator yotsekeka kapena fan yosagwira bwino ntchito.
