Ungakhetha kanjani i-coolant enhle?

Isipholile esikurediyetha sisiza ukugcina izinga lokushisa lenjini elilungile, elithinta ukusebenza kahle kakhulu kweyunithi yamandla. Ngokuvamile abashayeli bakhetha leyo eshibhile isibandisi, okungaholela ekuqhekekeni okuningi emotweni. Uketshezi oluncane kakhulu lungenza injini ishise noma ibambe. Ukuze ugweme ukwehluleka, kungcono ukhethe ama-coolants afakazelwe futhi aphezulu. Ngakho yiziphi izici zokupholisa okuhle? Funda futhi uhlole!

Kungani ukupholisa kubaluleke kangaka?

Imoto ifinyelela emazingeni okushisa aphezulu uma isebenza ngesivinini esiphezulu senjini. Okupholile igcina izinga lokushisa elifunekayo futhi ivimbele idivayisi ekushiseni ngokweqile. Njengoba izinga lokushisa likhuphuka, uketshezi ludlulisela ukushisa phakathi kwenjini ne-radiator ukuze kuhlakaze izinga lokushisa libuyele ohlelweni. I-coolant ihambisa ukushisa futhi ngaleyo ndlela ifudumeza ingaphakathi lemoto.

okupholisayo - ukukhiqizwa

I-coolant ikhiqizwa kanjani? Izinhlobo zobuchwepheshe zibalwe ngezansi:

• I-IAT (Inorganic Additive Technology) ubuchwepheshe obusebenzisa izithasiselo ezingaphili. Lezi zithako, okungukuthi i-silicates ne-nitrate, zakha umgoqo wokuvikela kusuka ngaphakathi nangaphezulu kwendawo yonke. Uketshezi olunjalo luguga ngokushesha, futhi uma lushiywe kurediyetha isikhathi eside, lungavimba imigudu yamanzi. Isipholisa ngobuchwepheshe be-IAT sizosebenza enjinini enodonga oluseceleni lwensimbi olusansimbi kanye nekhanda le-aluminium cylinder. Lolu hlobo lomkhiqizo lushintshwa kangcono njalo eminyakeni emibili;
• I-OAT (I-Organic Acid Technology) - esimweni salobu buchwepheshe, sibhekene nezithasiselo eziphilayo ekubunjweni. Lokhu kwenza ungqimba oluvikelayo lube mncane, nakuba lusebenza ngendlela efanayo. Uketshezi olunjalo lunamandla okudlulisa ukushisa aphezulu kune-IAT. Ubuchwepheshe be-OAT busetshenziswa kuphela ezimotweni zesizukulwane esisha. Awekho ama-lead solders kuma-radiator alezi zimoto. Uma kungenjalo, ukuvuza kungenzeka. Lawa mapholisa angahlala iminyaka emi-5;
• I-HOAT (Hybrid Organic Acid Technology) iyisipholisa esiyingxube esiqukethe izithasiselo eziphilayo kanye nama-reagents silicate. Lona umncintiswano othokozisayo we-ejenti ye-IAT. Lesi sakhiwo sizovumela uketshezi ukuthi luhlale isikhathi eside futhi luvikele ekugqwaleni.

Ukupholisa - Ukwakheka

Izinhlobo zokupholisa zingahlukaniswa futhi kwesinye isigaba. Ukwakheka kwesipholisa kungase kuhluke. Umkhiqizo uqukethe i-ethylene glycols noma i-propylene glycols:

• I-Ethylene glycol inephuzu lokubilisa eliphakeme kanye nephuzu elikhanyayo. Kubanda ku -11°C. Iwuketshezi olushibhile ukwenziwa futhi ine-viscosity ephansi. Emazingeni okushisa aphansi, icwebezela ngokushesha futhi ibambe ukushisa okuncane. Lesi akusona isipholile esivusa imizwa, futhi kufanele kwengezwe ukuthi sinobuthi obukhulu.;
• I-Propylene glycol ihlukile kunembangi yayo ngoba ayicwebezeli emazingeni okushisa aphansi. Ayinabuthi kakhulu, yingakho intengo yayo iphakeme.

Asebenza kanjani ama-glycols?

Izinga lokushisa le-ethylene glycol liyehla njengoba lihlanjululwa. Isixazululo esihle ukuxuba lobu tshwala namanzi. Kungani? Uma ungeza amanzi amaningi, isibandisi ngeke iqhwa ngokushesha. Ukuze uthole inani elifanele le-glycol emanzini akho, sebenzisa isilinganiso samanzi angu-32% kuya ku-68% we-glycol.

Ungakhetha kanjani i-coolant efanele?

Imikhiqizo eqediwe iyatholakala emakethe izibandisi noma okugxilile okudingeka kuhlanjululwe ngamanzi. Uma ungangezi amanzi, i-concentrate ngokwayo izoqala ukuqhwa ngo -16°C. Ukuze uhlambulule kahle uketshezi olujiyile, landela iziqondiso zomkhiqizi. Isipholisi esiqediwe sesivele sisesilinganisweni esifanele, ngakho-ke akukho lutho oludinga ukungezwa. Inzuzo yayo yizinga lokushisa eliqandayo, elifinyelela ku -30°C. Uma uzibuza ukuthi hlobo luni lweyunithi lubalulekile yini, impendulo ithi ukupholisa udizili kuzofana nanoma yiluphi olunye uhlobo lwenjini. 

Ngabe ama-coolants angahlanganiswa?

Uma unquma ukuhlanganisa uketshezi oluhlukene, udinga ukuhlola ngokucophelela ukwakheka kwabo. Kumele zibe nezithasiselo ezifanayo kanye nomsuka ofanayo. Uketshezi olunezithasiselo ezahlukene alukwazi ukuxutshwa, ngakho-ke ungaxubani, isibonelo, uketshezi nezithasiselo ezingaphili kanye noketshezi oluphilayo. Isiqandisi singasabela ukuze sakhe umgoqo ovikela kancane. 

Ushintsho lwamanzi

Okufanele ukwenze uma ungazi ukuthi iyiphi uketshezi okwamanje kurediyetha futhi udinga ukwengeza okwengeziwe? Isixazululo ukuthenga eyodwa jikelele. isibandisi. Umkhiqizo onjalo uqukethe izinhlayiya zokulwa nokubola ezingavikeli nje i-aluminium, kodwa futhi ithusi nensimbi. Ungaphinda usule isistimu yokupholisa ngaphambi kokwengeza isipholile esisha.

Yini enye okudingeka ukwazi mayelana nokupholisa?

Ezimweni lapho kudingekile ukwengeza amanzi ohlelweni lokupholisa, khumbula ukuthi kufanele kube ngamanzi a-distilled. Amanzi kampompi avamile anesandla ekwakhekeni kwesikali kulo lonke uhlelo. Kubaluleke ngokufanayo ukuthi uketshezi aluqini ebusika. Indawo yokubilisa yesipholisi kufanele ibe phakathi kuka-120-140 °C. I-concentrate yokupholisa etholakala ngokwentengiso kufanele ihlanjululwe ngamanzi ancibilikisiwe njenge uketshezi oluwugqinsi ngokwalo luyacwebezela kakade ku -10 °C.

Ingabe umbala wesipholisi unendaba?

Okuvame kakhulu imibala epholile ebomvu, ebomvana, eluhlaza okwesibhakabhaka nokuluhlaza. Lokhu kuvame ukuqokwa kobuchwepheshe bokukhiqiza, kodwa hhayi umthetho. I-IAT ivamise ukuba luhlaza okumnyama noma okuluhlaza okwesibhakabhaka ngombala. Uketshezi lwe-OAT ngokuvamile lubomvana, lubomvu, lunsomi, noma alunambala.

Kungani kunemibala ehlukahlukene kangaka uma kuziwa ekupholiseni? Umbala woketshezi ucaciswa abakhiqizi ngezizathu zokuphepha.. Konke lokhu ukuze kugwenywe ukusetshenziswa ngephutha, kanye nokwenza kwasendaweni kalula ukuvuza ohlelweni.

Isipholisi kufanele siguqulwe kangaki?

Ungakhohlwa ukushintsha ipholisa. Ukwehluleka ukwenza okuthile kungadala umonakalo omkhulu emotweni. ukusetshenziswa isibandisi umshayeli angase angaboni. Ukuntuleka kokupholisa okuhle kusho ukuthi uhlelo lokupholisa alusebenzi ngendlela efanele. Lokhu kungaholela ekusebenzeni kabi kwenjini kanye nethuba elikhulu lokugqwala. Abakhiqizi abaningi batusa ukushintsha uketshezi njalo eminyakeni emi-5 noma njalo ngo-200-250 km.

Imithetho ebalulekile lapho ushintsha uketshezi

Lapho ushintsha uketshezi, kufanele:

• sebenzisa isipholile esidizayinelwe le sistimu;
•  khetha njalo umkhiqizo onophawu. Ibiza kakhulu kunokuthatha indawo, uketshezi lusebenzisa ubuchwepheshe obusha futhi luqinisekisa ikhwalithi;
• shayela uhlelo lokupholisa ngaphambi kokushintsha ngakunye;
• ungaxubi uketshezi. Uma imoto iphuka ngenxa yokupholisa okuxubile, akekho umkhiqizi onesibopho somonakalo. Uma udinga ukwengeza uketshezi, khetha umkhiqizo onophawu, obiza kakhulu. Lapho uketshezi luguga, buyisela olusha.

Ukupholisa - yimiphi imiphumela yokukhetha okungalungile?

Imiphumela yoketshezi oludala noma olungafanele ingahluka. Okuvame kakhulu ukuthi:

• ukugqwala kwalo lonke uhlelo;
• asikho isithiyo esivikelayo.

Isipholile esidala

Isizathu esivame kakhulu sokugqwala ohlelweni lokupholisa isipholile esidala esishiywe isikhathi eside kakhulu. Ukugqwala kusho ukuthi kumile ukusebenza. Ngesikhathi sokusebenza, uketshezi oludala lungase luqale ukukhihliza igwebu. Kwakudala isibandisi i-glycol encane kakhulu, engabangela injini ukuba ishise kakhulu. Qaphela futhi:

• amanzi kampompi noma distilled;
• uketshezi olungafanelekile ku-radiator.

Thepha noma amanzi acwecwe

Lokhu kungaholela ekushiseni ngokweqile kwenjini futhi, ngenxa yalokho, i-jamming yayo. Ukusetshenziswa kwayo kungaholela ekuvaleni kwe-heater kanye nokupholisa ngesilinganiso.

Uketshezi olukhethwe ngokungalungile lwe-radiator

Uma ukhetha umkhiqizo ongalungile, yonke isistimu yokupholisa ingase igle. Ukugqwala kungahlasela izingxenye ezithile zensimbi.

Lapho ukhetha i-coolant, naka ukwakheka kanye nezithasiselo. Qinisekisa ukuthi uhlobo olulungile lomkhiqizo lusesimweni sokupholisa. Khona-ke uzoqiniseka ukuthi akukho lutho oluzolimala. I-coolant yezimoto igcina yonke injini isebenza ngama-RPM aphansi naphezulu. Ngakho-ke khumbula ukuyishintsha njalo futhi uzame ukugwema izinto ezishibhile kanye nokuxuba izinto.
