Iyini imbiza yokwandisa imoto
Imbiza yokwandisa izimoto , eyaziwa nangokuthi ithangi lokukhulisa noma ithangi elisizayo, iyingxenye ebalulekile yesistimu yokupholisa izimoto. Umsebenzi wayo oyinhloko ukuhlinzeka ngendawo yokukhulisa ye-coolant, ukumunca igesi eningi kanye nengcindezi ekhiqizwa ngesikhathi sokusebenza kwesistimu yokupholisa, nokuqinisekisa ukusebenza okuzinzile kwesistimu yokupholisa.
Umsebenzi oyisisekelo wembiza yokwandisa
Ukucindezela kokumuncwa: Uma i-coolant ijikeleza enjinini, i-coolant izokhula ngenxa yesimiso sokwanda kokushisa kanye nokuncipha kokubanda. Ibhodwe lokunweba limunca i-coolant enwetshiwe futhi livimbele ukucindezela kohlelo ukuthi kungabi phezulu kakhulu, ngaleyo ndlela livikele uhlelo lokupholisa ekulimaleni.
Igesi ehlukanisiwe : Isibandisi sikhiqiza amagesi ngesikhathi sokujikeleza kwegazi, uma sishiywa ohlelweni, azobangela ukwehla kokusebenza kahle kokushabalalisa ukushisa. Ibhodwe lokunweba lingawahlukanisa la magesi, liqinisekise ukuthi isibandisi sihlanzekile futhi ukushisa kuyashabalalisa kahle.
Lungisa inani le-coolant: imbiza yokwandisa ingasetshenziswa njengesitsha sokwengeza i-coolant, uma i-coolant inganele, ungangeza i-coolant ngayo ukuqinisekisa ukuthi injini ihlala ine-coolant eyanele yokushisa.
Isakhiwo kanye nohlobo lwembiza yokwandisa
Kunezinhlobo ezimbili eziyinhloko zama-expansion POTS: ama-atmospheric expansion POTS kanye nama-high-pressure expansion POTS.
Imbiza yokwandisa esemoyeni: Lolu hlobo lwembiza yokwandisa aluxhumene ngqo nesistimu yokupholisa, futhi izinga layo loketshezi alikwazi ukukhombisa ngokugcwele inani eliphelele le-coolant ohlelweni lokupholisa. Uma i-coolant inganele, hlola lonke uhlelo lokupholisa ngaphambi kokugcwalisa i-coolant ebhodweni lokukhulisa.
Imbiza yokwandisa enomfutho ophezulu: lolu hlobo lwembiza yokwandisa luxhunywe ngqo ohlelweni lokupholisa, futhi izinga loketshezi lingabonisa ngqo inani eliphelele le-coolant ohlelweni lokupholisa, ngakho-ke kulula ukwahlulela ukuthi kuyadingeka yini ukwengeza i-coolant.
Ukunakekelwa kwembiza yokwandisa kanye nezincomo zokusetshenziswa
Ukuhlolwa okwenziwa ngezikhathi ezithile: Hlola njalo umugqa wophawu lwezinga loketshezi lwebhodwe lokunweba ukuqinisekisa ukuthi izinga loketshezi ligcinwa phakathi kwezinga eliphezulu neliphansi kakhulu. Uma izinga loketshezi liphansi kakhulu, i-coolant kufanele ifakwe ngesikhathi.
Gwema ukuvula lapho injini ishisa kakhulu: ungavuli isivalo sokunweba lapho injini ishisa, njengoba ingcindezi yangaphakathi iphakeme, okungase kubangele ingozi.
Hlola ivalvu yokukhulula ingcindezi: Ivalvu yokukhulula ingcindezi iyingxenye ebalulekile yebhodwe lokukhulisa. Uma yehluleka, ingcindezi ayikwazi ukukhululwa futhi ingalimaza ibhodwe lokukhulisa noma lonke uhlelo lokupholisa.
Imbiza yokwandisa izimoto inemisebenzi eminingi ohlelweni lokupholisa izimoto, ikakhulukazi okuhlanganisa ukumunca ingcindezi, ukuhlukanisa igesi nokuvimbela i-coolant ukuthi ingashisi.
Okokuqala, imbiza yokwandisa ingamunca ingcindezi ohlelweni. Lapho injini isebenza, uhlelo lokupholisa luzokhiqiza ingcindezi ethile, uma ipayipi lesistimu yokupholisa liholela ngqo emoyeni, lizoholela ekuhwamukeni kwe-coolant kanye noshintsho lwempahla yamakhemikhali, okuthinta umphumela wokupholisa. Ngokuvala uhlelo lokusebenza, imbiza yokwandisa imunca futhi iqukathe ingcindezi ekhiqizwa uhlelo ukuqinisekisa ukusebenza okuzinzile kohlelo.
Okwesibili, ibhodwe lokunweba lihlukanisa igesi ukuqinisekisa ukusebenza kahle kokushabalalisa ukushisa. Lapho injini isebenza, igesi izokhiqizwa ohlelweni lokupholisa. Uma la magesi ejikeleza epayipini, igesi izovinjelwa epayipini lokushabalalisa ukushisa, okuthinta umphumela wokushabalalisa ukushisa. Ibhodwe lokunweba lingahlukanisa futhi liqukathe la magesi ukuvimbela ukuvaleka kwegesi nokuqinisekisa ukusebenza kahle kokushabalalisa ukushisa.
Ngaphezu kwalokho, imbiza yokwandisa ivimbela i-coolant ukuthi ingabi ngumhwamuko. Njengoba ingxenye eyinhloko ye-coolant kungamanzi, amanzi azohwamuko emazingeni okushisa aphezulu, okuholela ekunciphiseni kwe-coolant. Imbiza yokwandisa yakhelwe ngesistimu evaliwe ukuvimbela i-coolant ukuthi ingabi ngumhwamuko nokugcina ukusebenza okuzinzile kwesistimu.
Okokugcina, izici zomklamo webhodwe lokunweba zifaka phakathi izindawo zokuxhumanisa amapayipi amanzi phezulu nangaphansi. Ipayipi elisengxenyeni engenhla yethangi liyindawo yokubuyela emuva, lapho i-coolant igeleza khona iphindela ebhodweni; Elisezansi kwethangi liyindawo yokuphuma kwamanzi, eholela ngqo empompini yenjini, igcwalisa ipompo nge-antifreeze. Kukhona futhi uphawu olucacile eketeleni olubonisa imikhawulo ephezulu nephansi ye-coolant.
