Umgomo wokusebenza kwethangi lokunweba imoto
Ithangi lamanzi lokunweba izimoto (elaziwa nangokuthi idamu lamanzi lokunweba) liyingxenye ebalulekile ohlelweni lokupholisa injini. Ngokuyinhloko liqinisekisa ukusebenza okuvamile kwenjini ngemisebenzi emithathu: ukulawula ingcindezi yesistimu, ukwamukela ukunwebeka nokufinyela kwe-coolant ngenxa yokushisa nokubanda, kanye nokuhlukanisa nokukhipha amagesi.
Isimiso sokusebenza esiyinhloko
Ukulawulwa kwengcindezi kanye nokukhululeka kokuphepha: Lapho i-coolant ikhula ngenxa yokushisa, ingcindezi yesistimu iyanda. Lapho ingcindezi idlula i-0.12 MPa (cishe ama-atmospheres angu-1.2), ivalvu yomusi esembozweni sethangi lamanzi elinwetshiwe izovuleka ngokuzenzakalelayo ukuze ikhulule umusi othile emkhathini ukuze ivimbele ingcindezi yesistimu ukuthi ingabi phezulu kakhulu futhi ibangele ukuthi amapayipi noma ithangi lamanzi liqhume. Ngemva kokupholisa, ingcindezi yesistimu iyancipha, futhi ivalvu yomoya izovuleka ukuze imunce umoya ukuze ivimbele ukwakheka kwe-vacuum, igweme ukuthi iphampu yamanzi ingamunci owomile.
Ukwamukela izinguquko kumthamo we-coolant: Ngesikhathi sokusebenza kwenjini, njengoba izinga lokushisa le-coolant likhuphuka, umthamo wayo uyanda, bese i-coolant eyengeziwe igeleza iye ethangini lamanzi okwandisa; lapho injini icishiwe futhi ipholiswa, i-coolant iyafinyela, bese i-coolant esethangini lamanzi okwandisa izobuyela ohlelweni lokujikeleza oluyinhloko ukuze kufezwe ukugcwaliswa kabusha kwe-coolant okuzenzakalelayo.
Ukuhlukaniswa kwegesi yamanzi kanye nokukhipha umoya: Lona umsebenzi obaluleke kakhulu. Ngesikhathi sokusebenza kohlelo lokupholisa, kukhiqizwa amabhamuza omusi noma umoya, ahlukaniswa ne-coolant ngokusebenzisa umklamo wokuhlukanisa amanzi negesi. Umusi uzohlangana ube ngamanzi ethangini lamanzi abandayo bese ugeleza ubuyele ohlelweni, kuyilapho umoya ukhishwa. Lokhu kuvimbela ngempumelelo isimo sokuvaleka kwegesi futhi kuqinisekisa ukujikeleza kwe-coolant okubushelelezi, kugweme ukushisa ngokweqile kwenjini.
Kungani kudingeka?
Vimbela "ukubila ngaphezulu": Ngokukhulula ingcindezi, kugwema ukuthi ingcindezi yesistimu yokupholisa ibe phezulu kakhulu futhi kubangele ukuthi i-coolant ibile futhi igcwale.
Vikela iphampu yamanzi: Ngokuhlukanisa amagesi, kuvimbela iphampu yamanzi "ekugugulekeni komoya" futhi kwandisa isikhathi sokuphila kwephampu.
Gcina ukusebenza kahle kokupholisa: Ngokuzinzisa ingcindezi kanye nezinga loketshezi, kuqinisekisa ukuthi uhlelo lokupholisa luhlala lusesimweni esihle kakhulu sokusebenza.
Kalula nje, ithangi lamanzi elinwetshiwe lifana "nethangi le-buffer" kanye "nesiteshi sokukhipha umoya" sohlelo lokupholisa. Lisebenza buthule ukuqinisekisa ukuthi injini igcina izinga lokushisa elizinzile ngaphansi kwezimo zokusebenza ezahlukahlukene.
Izinkinga ezivamile zethangi lamanzi elinwetshiwe zigxile kakhulu kulezi zici ezilandelayo: ukwehluleka kwesembozo, ukuvuza, ingcindezi yangaphakathi engavamile, kanye nokwehluleka kwenzwa. Ake ngikusize uzicacise:
Ukwehluleka kwesembozo sethangi lamanzi lokukhulisa
Lena yindawo evame kakhulu yokwehluleka. Ivalvu yomusi kanye nevalvu yomoya ngaphakathi kwesembozo kunesibopho sokulawula ingcindezi.
Izimpawu: I-coolant iphuma ephepheni, injini ishisa kakhulu futhi ibila ngisho, i-coolant iphuma emapayipini ibangele ukuqhekeka.
Izizathu: Ama-valve awakwazi ukuvula ukuze akhulule ingcindezi ngokujwayelekile (njengokuphuka kokukhiqiza, ukuguguleka kwesikhathi eside, ukuvaleka kokungcola noma umonakalo wangaphandle).
Ukuvuza kwethangi lamanzi okwandisa
Isibandisi sizophuma emzimbeni wethangi lamanzi noma ezindaweni zokuxhuma.
Izimpawu: Uketshezi olupholisayo luvela phansi kwethangi lamanzi noma emhlabeni wonke, ukwehla okuqhubekayo kwevolumu yokupholisa, ukupholisa injini okungekuhle.
Izizathu: Izinto zethangi lamanzi ziyaguga futhi ziyaqhekeka, amapayipi okuxhuma axegayo noma ukuvala okungahambi kahle, ingcindezi yangaphakathi ngokweqile ebangela ukuqhekeka kwamaphuzu abuthakathaka.
Ingcindezi yangaphakathi engavamile
Ukwehluleka kwesembozo noma ukuvaleka kwesistimu kuzobangela ukungalingani kwengcindezi.
Izimpawu: Ukuvutha kwe-coolant, ukushisa kakhulu kwenjini, isibani sesexwayiso sezinga eliphansi le-coolant sivuliwe.
Izizathu: I-valve yokumboza inamathele (ngokuvamile ivaliwe noma ivame ukuvuleka), ukuvaleka komoya ohlelweni lokupholisa.
Ukwehluleka kwenzwa yezinga loketshezi (amanye amamodeli afakiwe)
Inzwa inesibopho sokuqapha izinga le-coolant kanye nokuqalisa ama-alamu.
Izimpawu: I-alamu engalungile kudeshibhodi, ukubonisa izinga loketshezi elinganembile, ukungakwazi ukuqala isixwayiso esisezingeni eliphansi.
Izizathu: Izikhonkwane zenzwa ezonakele, ukuntanta kuvinjiwe yizinto zangaphandle, ukwehluleka kwezintambo.
Ezinye izinkinga ezihlobene
Ukwehluleka kwebholthi lokukhipha ugesi: Amanye amathangi amanzi anamabholthi okukhipha ugesi avuzayo noma aphukile, okwenza uhlelo luhluleke ukukhipha ugesi kahle noma lulahlekelwe ukuvalwa.
Ukuguga Okusheshayo: Ukusebenzisa amanzi ompompi esikhundleni se-coolant kuzosheshisa ukuguga kwethangi lamanzi kanye nokumboza, njengoba amanzi enendawo yokubila ephansi futhi evame ukugqwala.
Umthelela wephutha
Uma kungaxazululwanga ngesikhathi, kungaholela ekushiseni ngokweqile kwenjini, ukubila ngokweqile, amandla anciphile, ukuguguleka okukhulu kwezingxenye, ngisho nokwehluleka kwemishini njengokubanjwa kwesilinda.
Iziphakamiso zokuhlola ezimfushane:
Ukuhlolwa okubonakalayo: Hlola njalo ukubukeka kwethangi lamanzi, izindawo zokuxhuma, kanye nomhlabathi ukuze uthole iminonjana yokupholisa.
Lalela imisindo engavamile: Qaphela ukuthi ngabe kukhona yini umsindo ongavamile wokufutha i-coolant kusuka ekhava lapho uqala.
Qapha iphaneli yethuluzi: Qaphela ukuthi isibani sesixwayiso sokushisa kwamanzi sivuliwe yini.
Ukuxilongwa kobungcweti: Uma usola izinkinga zokucindezela noma ukwehluleka kwezinzwa, kunconywa ukusebenzisa imishini yobungcweti ukuhlola ukucindezela kohlelo nokufunda amakhodi ephutha.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
