Ntchito ya makina oziziritsa magalimoto ndi kutaya kutentha kwa injini mu nthawi, kuti injini igwire ntchito pa kutentha koyenera kwambiri.Njira yabwino yoziziritsira galimoto sayenera kungokwaniritsa zofunikira za kuziziritsa kwa injini, komanso kuchepetsa kutaya kwa kutentha ndi kugwiritsira ntchito mphamvu, kuti injini ikhale ndi mphamvu yopulumutsa mphamvu pamaziko a kuonetsetsa kuti mphamvu ikuyenda bwino.

I. Mfundo yogwira ntchito ya dongosolo lozizira

Dongosolo lozizira limagwira ntchito yofunika kwambiri m'galimoto, makina oziziritsa a injini nthawi zambiri amatenga kuziziritsa kwamadzi, njira yoziziritsira yomwe imapangidwa ndi radiator, paipi ya radiator, thermostat, pampu yamadzi, fan yoziziritsa ndi lamba wa fan.

Zimadalira pampu yamadzi ozizira yomwe imadutsa mu chozizira chamafuta, jekete lamadzi loziziritsa la crankcase ndikupita kumutu wa silinda, kutengera kutentha kwa injini.

Kuzungulira kwakukulu: injini ikamagwira ntchito motenthedwa bwino, ndiye kuti, kutentha kwamadzi kumakhala kopitilira 80 ℃, madzi ozizira ayenera kudutsa mu radiator kuti apange kufalikira kwakukulu.Vavu yaikulu ya thermostat imatsegulidwa kwathunthu ndipo valavu yachiwiri yatsekedwa kwathunthu.

Kuzungulira pang'ono: pamene kutentha kwa madzi ozizira kuli pansi pa 70 ℃, kuthamanga kwa nthunzi mu bokosi lokulitsa kumakhala kochepa kwambiri, ndipo madzi ozizira samadutsa pa radiator, koma amangoyendetsa pang'ono pakati pa jekete lamadzi ndi mpope.

Awiri, udindo wa ozizira

Chozizira chimakhala ndi gawo lofunikira kwambiri pakugwira bwino ntchito kwa injini.Kutentha kwambiri kapena kutsika kwambiri kwa choziziritsira kungayambitse vuto la injini.Ngati kutentha kwa zoziziritsa ku injini kuli kokwera kwambiri ndipo kukhuthala kwa mafuta opaka kumachepetsedwa, kuwonongeka kwa zida za injini kumakulirakulira.

Ngati kutentha kwa injini yozizirirako kumakhala kotsika kwambiri, kukhuthala kwamafuta opaka mafuta kumawonjezeka ndipo madziwo amakhala ocheperako, omwenso sangagwirizane ndi mafuta, motero amachepetsa mphamvu ya injini ndikusokoneza magwiridwe antchito a injini.

Coolant ndi sing'anga kutentha kutengerapo mu dongosolo kuzirala, ndi kuzirala, odana ndi dzimbiri, anti-scale ndi odana ndi kuzizira ndi ntchito zina, wapangidwa ndi madzi, antifreeze ndi zina zosiyanasiyana.

1. Madzi ndi gawo lofunika kwambiri la choziziritsira.Ili ndi mphamvu yayikulu yotentha komanso kutentha kwachangu, ndipo kutentha komwe kumatengedwa ndi madzi ndikosavuta kutulutsa.

2. Antifreeze ndi kuchepetsa kuzizira kwa ozizira.Chifukwa cha kuzizira kwambiri kwa madzi, zimakhala zosavuta kuzizira ngati zikugwiritsidwa ntchito nyengo yozizira komanso yotsika kwambiri.

3. Zina zowonjezera

Zowonjezera nthawi zambiri zisapitirire 5%, makamaka corrosion inhibitor, buffer, anti-scale agent, antifoaming agent ndi colorant.

(1) Corrosion inhibitor: imatha kupewa dzimbiri zachitsulo munjira yozizira, chifukwa payipi yozizirira imapangidwa makamaka ndi zigawo zachitsulo, ndipo dongosolo lozizilitsa limakonda dzimbiri ndi kuwonongeka chifukwa cha kuthamanga kwambiri, katundu wotentha. ndi corrosive medium.

(2) Scale inhibitor: imatha kuchotsa bwino sikelo ndikuwongolera kutentha kwapang'onopang'ono.Pogwiritsa ntchito zoziziritsa kukhosi, sikelo nthawi zambiri imapangidwa mkati mwa dongosolo lozizirira.The matenthedwe madutsidwe sikelo ndi otsika kuposa zitsulo, amene kwambiri amakhudza yachibadwa kutentha dissipation.

(3) antifoaming wothandizira: amatha kuteteza thovu, ozizira mu mpope pa liwiro lalikulu pansi pa kufalitsidwa anakakamizika, kawirikawiri kutulutsa thovu, thovu zambiri osati bwanji kutentha kutengerapo dzuwa, komanso kukulitsa dzimbiri cavitation wa mpope.

(4) colorant: pogwiritsira ntchito zoziziritsa kukhosi, nthawi zambiri zimafunika kuwonjezera mtundu wina, kuti choziziritsa chikhale ndi mtundu wodabwitsa.Mwa njira iyi, pamene dongosolo loziziritsa likulephera, malo otayira amatha kudziŵika mosavuta poyang'ana payipi yakunja ya dongosolo lozizira.

Chachitatu, gulu la zoziziritsa kukhosi

Injini yozizira imagawidwa kukhala glycol coolant ndi propylene glycol coolant malinga ndi antifreeze:

1, ethylene glycol yeniyeni kutentha mphamvu, matenthedwe madutsidwe, mamasukidwe akayendedwe ndi kuwira mfundo magawo zofunika zimene zimakhudza kutentha kutengerapo ntchito ya ethylene glycol amadzimadzi njira.Kutentha kwapadera ndi matenthedwe a ethylene glycol amadzimadzi amadzimadzi amachepetsa ndi kuwonjezeka kwa ndende, ndipo kukhuthala kumawonjezeka ndi kuwonjezeka kwa ndende.

2, propylene glycol pochepetsa kuzizira kozizira komanso glycol ndizofanana, komanso zocheperako kuposa glycol, mtengo wake ndi wokwera mtengo kuposa glycol.

Chachinayi, kukonza dongosolo yozizira

1. Kusankha kozizira

(1) Pofuna kupewa kuzizira kwa kuzizira, antifreeze yoyenera ikhoza kusankhidwa.Nthawi zambiri, kuzizira kwa antifreeze kumayenera kutsika ndi 5 ℃ poyerekeza ndi kutentha kochepa kwambiri m'deralo.

(2) Mitundu yosiyanasiyana ya antifreeze siyingasakanizidwe.

2. Nthawi yosinthira ndikugwiritsa ntchito

(1) Njira yosinthira: Zoziziritsa zimayenera kusinthidwa kamodzi pazaka 2-3, malinga ndi buku la opareshoni.

(2) Kuwonjeza kuchuluka: Antifreeze iyenera kuwonjezeredwa ku thanki yowonjezera pakati pa F (MAX) ndi L (MIN) zizindikiro m'malo ozizira a injini.

3. Kusamalira tsiku ndi tsiku:

(1) Chisamaliro chatsiku ndi tsiku chiyenera kuperekedwa pakuwunika, pakapanda kuziziritsa kosakwanira, zizindikiro zoyera pamwamba pa chitoliro chamadzi kapena mkaka woyera m'mafuta, ndiko kutuluka kwa choziziritsa.

(2) Yang'anani malo olumikizirana komanso momwe ma hose onse ozizirira ndi ma heaters amatenthetsera.Ngati pali kukulitsa kapena kuwonongeka, chonde sinthani munthawi yake.

Chidule: Dongosolo lozizira limagwira ntchito yofunika kwambiri m'galimoto.Poigwiritsa ntchito tsiku ndi tsiku, iyenera kusamalidwa pafupipafupi, kuti ipumule ndi mphepo ndikupangitsa kuti galimotoyo ikhale yabwino.Iyenera kuyang'aniridwa pafupipafupi ngati choziziritsira injini chikukwanira, ndipo chozizirira choyenera chiyenera kuwonjezeredwa kapena kusinthidwa pakafunika nthawi.
