Momwe mungasankhire choziziritsa bwino?

Choziziritsa mu rediyeta chimathandizira kusunga kutentha kwa injini koyenera, komwe kumakhudza magwiridwe antchito abwino kwambiri amagetsi. Nthawi zambiri madalaivala amasankha yomwe ili yotsika mtengo chozizira, zomwe zingayambitse kuwonongeka kwa galimoto. Madzi ochepa kwambiri amathanso kuchititsa injini kutenthedwa kapena kugwira. Kuti mupewe kulephera, ndi bwino kusankha zoziziritsa kukhosi zotsimikiziridwa komanso zapamwamba. Ndiye mawonekedwe a chozizira bwino ndi chiyani? Werengani ndikuwona!

Chifukwa chiyani kuzizira kuli kofunika kwambiri?

Galimoto imafika kutentha kwambiri ikamathamanga kwambiri injini. Wozizilitsa imasunga kutentha komwe kumafunikira ndikuletsa chipangizocho kuti chisatenthedwe. Pamene kutentha kumakwera, madzimadzi amasuntha kutentha pakati pa injini ndi radiator kuti amwaze kutentha kubwerera mu dongosolo. Choziziriracho chimagawira kutentha ndipo motero chimatenthetsanso mkati mwagalimoto.

ozizira - kupanga

Kodi zoziziritsa kukhosi zimapangidwa bwanji? Mitundu yaukadaulo yalembedwa pansipa:

• IAT (Inorganic Additive Technology) ndi teknoloji yomwe imagwiritsa ntchito zowonjezera zowonjezera. Zowonjezera izi, i.e. silicates ndi nitrates, zimapanga chotchinga choteteza kuchokera mkati ndi pamwamba pa nthaka yonse. Zakumwa zoterezi zimatha msanga, ndipo ngati zitasiyidwa mu radiator kwa nthawi yayitali, zimatha kutsekereza njira zamadzi. Zoziziritsa ndi ukadaulo wa IAT zitha kugwira ntchito mu injini yokhala ndi chitsulo cham'mbali mwachitsulo komanso mutu wa silinda wa aluminiyamu. Mtundu uwu wa mankhwala bwino m'malo zaka ziwiri zilizonse;
• OAT (Organic Acid Technology) - pankhani yaukadaulo uwu, tikulimbana ndi zowonjezera zomwe zili muzolembazo. Izi zimapangitsa kuti chitetezo cha mthupi chikhale chochepa kwambiri, ngakhale chimakhala chothandiza. Madzi oterowo amakhala ndi kutentha kwambiri kuposa IAT. Ukadaulo wa OAT umangogwiritsidwa ntchito pamagalimoto am'badwo watsopano. Palibe zogulitsira zotsogola m'ma radiator a magalimoto awa. Apo ayi, kutayikira kungachitike. Zozizirazi zimatha mpaka zaka 5;
• HOAT (Hybrid Organic Acid Technology) ndi chozizira chosakanizidwa chokhala ndi zowonjezera za organic ndi ma reagents a silicate. Uwu ndi mpikisano wosangalatsa kwa wothandizira wa IAT. Kapangidwe kameneka kamapangitsa kuti madziwo azikhala nthawi yayitali komanso kuteteza ku dzimbiri.

Kozizira - Kupanga

Mitundu ya zoziziritsa kuzizira zimathanso kusiyanitsa m'gulu lina. Mapangidwe a zoziziritsa kukhosi angasiyane. Mankhwalawa ali ndi ethylene glycols kapena propylene glycols:

• Ethylene glycol ili ndi malo otentha kwambiri komanso kung'anima. Kuzizira pa -11°C. Ndimadzimadzi otsika mtengo kupanga ndipo ali ndi kukhuthala kochepa. Kukatentha kwambiri, imanyezimira mofulumira ndipo imatenga kutentha kochepa. Ichi sichiri choziziritsa kukhosi, ndipo chiyenera kuwonjezeredwa kuti ndi poizoni kwambiri.;
• Propylene glycol imasiyana ndi mpikisano wake chifukwa sichimatentha kwambiri. Ndiwochepa kwambiri poizoni, chifukwa chake mtengo wake ndi wapamwamba.

Kodi ma glycols amagwira ntchito bwanji?

Kutentha kwa ethylene glycol kumatsika pamene kuchepetsedwa. Njira yabwino ndikusakaniza mowa ndi madzi. Chifukwa chiyani? Ngati muwonjezera madzi, chozizira sizimazizira kwambiri. Kuti mupeze kuchuluka kwa glycol m'madzi anu, gwiritsani ntchito madzi 32% mpaka 68% glycol.

Momwe mungasankhire choziziritsa choyenera?

Zotsirizidwa zilipo pamsika zoziziritsa kukhosi kapena zoyika zomwe zimafunika kuchepetsedwa ndi madzi. Ngati simukuwonjezera madzi, chokhazikikacho chimayamba kuzizira pa -16°C. Kuti musungunuke bwino madzi osungunuka, tsatirani malangizo a wopanga. Zoziziritsa zomalizidwa kale zili bwino, kotero palibe chomwe chiyenera kuwonjezeredwa. Ubwino wake ndi kutentha kozizira, komwe kumafika -30°C. Ngati mukudabwa ngati mtundu wa unit ndi wofunika, yankho ndiloti chozizira cha dizilo chidzakhala chofanana ndi mtundu wina uliwonse wa injini. 

Kodi zotsekemera zimatha kusakanizidwa?

Ngati mwasankha kuphatikiza zamadzimadzi zosiyanasiyana, muyenera kuyang'ana mosamala kapangidwe kake. Ayenera kukhala ndi zowonjezera zofanana ndi chiyambi chomwecho. Zamadzimadzi zomwe zili ndi zowonjezera zosiyanasiyana sizingasakanizidwe, chifukwa chake musasakanize, mwachitsanzo, madzi okhala ndi zowonjezera komanso zamadzimadzi. Firiji imatha kuchitapo kanthu kuti ipange chotchinga chocheperako. 

Kusintha kwamadzimadzi

Zoyenera kuchita ngati simukudziwa kuti ndi madzi ati omwe ali mu radiator ndipo muyenera kuwonjezera zina? Njira yothetsera vutoli ndikugula chilengedwe chonse. chozizira. Zoterezi zimakhala ndi tinthu tating'onoting'ono tomwe timateteza aluminium, komanso mkuwa ndi chitsulo. Mukhozanso kutsuka makina ozizirira musanawonjezeko chozizirirapo chatsopano.

Ndi chiyani chinanso chomwe muyenera kudziwa za coolant?

Munthawi yomwe kuli kofunikira kuwonjezera madzi panjira yozizira, kumbukirani kuti iyenera kukhala madzi osungunuka. Madzi apampopi wamba amathandizira kupanga sikelo mu dongosolo lonse. Ndikofunikiranso kuti madziwo asaundane m'nyengo yozizira. Kuwira kwa koziziritsira kuyenera kukhala pakati pa 120-140 ° C. Kuzizirira komwe kumapezeka pamalonda kumayenera kuchepetsedwa ndi madzi opanda mchere monga madzi wandiweyani pawokha crystallizes kale pa -10 °C.

Kodi mtundu wa choziziracho ndi wofunika?

Chofala kwambiri ozizira mitundu wofiira, pinki, buluu ndi wobiriwira. Izi nthawi zambiri zimatchulidwa zaukadaulo wopanga, koma osati lamulo. IAT nthawi zambiri imakhala yobiriwira kapena yabuluu. Madzi a OAT nthawi zambiri amakhala apinki, ofiira, ofiirira, kapena opanda mtundu.

N'chifukwa chiyani pali mitundu yosiyanasiyana chonchi pankhani yozizirira? Mtundu wa zakumwa umatchulidwa ndi opanga chifukwa cha chitetezo.. Zonsezi pofuna kupewa kumwa mwangozi, komanso kuti muchepetse kutayikira kwadongosolo.

Kodi choziziriracho chiyenera kusinthidwa kangati?

Musaiwale kusintha choziziritsa kukhosi. Kulephera kuchitapo kanthu kungayambitse kuwonongeka kwakukulu kwa galimotoyo. kumwa chozizira dalaivala sangazindikire. Kupanda zoziziritsira bwino kumatanthauza kuti makina ozizirawo sakugwira ntchito bwino. Izi zitha kupangitsa kuti injini isagwire bwino ntchito komanso mwayi wokulirapo wa dzimbiri. Opanga ambiri amalangiza kusintha madzimadzi zaka 5 zilizonse kapena 200-250 km iliyonse.

Malamulo ofunikira posintha madzimadzi

Mukasintha madzi, muyenera:

• gwiritsani ntchito zoziziritsa kukhosi zopangidwira dongosolo lino;
•  nthawi zonse sankhani chinthu chodziwika bwino. Zokwera mtengo kuposa zolowa m'malo, zamadzimadzi zimagwiritsa ntchito matekinoloje atsopano ndikutsimikizira kuti zili bwino;
• tsitsani dongosolo lozizirira musanalowe m'malo;
• osasakaniza zamadzimadzi. Galimoto ikawonongeka chifukwa cha kuzizira kosakanikirana, palibe wopanga yemwe ali ndi udindo wowonongeka. Ngati mukufuna kuwonjezera zakumwa, sankhani chinthu chodziwika, chokwera mtengo. Madzimadzi akatha, m'malo mwake ndi atsopano.

Zozizira - zotsatira za kusankha kolakwika ndi chiyani?

Zotsatira za madzi akale kapena osayenera akhoza kukhala osiyana. Nthawi zambiri ndi:

• kuwonongeka kwa dongosolo lonse;
• palibe chotchinga choteteza.

Zozizira zakale

Chomwe chimayambitsa dzimbiri m'zigawo zozizirira ndi choziziritsira chakale chomwe chasiyidwa kwa nthawi yayitali. Kuwonongeka kumatanthauza kuti yasiya kugwira ntchito. Pa ntchito, madzimadzi akale angayambe thovu. M'zakale chozizira glycol yochepa kwambiri, yomwe ingayambitse injini kutenthedwa. Onetsetsaninso:

• madzi apampopi kapena osungunuka;
• madzimadzi osayenera kwa zida za radiator.

Pampopi kapena madzi osungunuka

Izi zingayambitse kutenthedwa kwa injini ndipo, chifukwa chake, kugwedezeka kwake. Kugwiritsa ntchito kwake kungayambitse kutsekeka kwa chotenthetsera komanso kuzizira ndi sikelo.

Madzi osankhidwa molakwika azinthu za radiator

Ngati musankha mankhwala olakwika, dongosolo lonse lozizira likhoza kuwononga. Dzimbiri limathanso kuwononga zitsulo zina.

Posankha choziziritsa kukhosi, tcherani khutu ku kapangidwe kake ndi zowonjezera. Onetsetsani kuti mtundu wolondola wa mankhwala uli m'dongosolo lozizirira. Ndiye mudzakhala otsimikiza kuti palibe chomwe chidzawonongeka. Zoziziritsa zamagalimoto zimasunga injini iliyonse ikuyenda pama RPM otsika komanso okwera. Chifukwa chake kumbukirani kuyisintha pafupipafupi ndikuyesa kupewa zotsika mtengo komanso kusakaniza zinthu.
