I-thermostat yemoto eyinhloko
Umonakalo we-thermostat yemoto ungaholela ekushiseni kwenjini okungalawuleki, okubonakala njengokushisa ngokweqile kwenjini noma ukwehluleka ukufinyelela izinga lokushisa lokusebenza elijwayelekile. Lokhu, nakho, kubangela uchungechunge lwezinkinga zokusebenza nokuqina.
Umthelela oyinhloko kanye nokubonakaliswa okuthile
Umonakalo we-thermostat ungahlukaniswa ngezimo ezimbili: ukubhajwa endaweni evulekile noma ukubhajwa endaweni evaliwe. Lezi zimo ezimbili zinemiphumela ehluke ngokuphelele emotweni.
I-thermostat ivuliwe (injini ayikwazi ukufudumala)
Ukusetshenziswa kukaphethiloli kuyanda kakhulu: Injini isebenza ezingeni lokushisa eliphansi isikhathi eside, futhi uphethiloli awufakwanga kahle. Ikhompyutha izokwandisa ivolumu yokufaka uphethiloli ukuze iqhubeke isebenza, futhi ukusetshenziswa kukaphethiloli kunganda ngo-10%-15%.
Ukwehluleka kokunikezwa komoya oshisayo noma umphumela omubi kakhulu: Ukushisa kulahleka njalo ekujikelezeni okukhulu kwe-coolant, okuholela ekushiseni komoya okuphansi okuvela ohlelweni lokushisa, okuthinta kakhulu induduzo yokushayela nokugibela ebusika.
Ukwanda kokuguguleka kwenjini namandla ancishisiwe: Emazingeni okushisa aphansi, uwoyela wenjini une-viscosity ephezulu, futhi umphumela wokuthambisa uyancipha. Ukumelana nokungqubuzana kwezingxenye zangaphakathi kuyanda, kusheshise ukuguguleka futhi kubangele ukukhishwa kwamandla okunganele. Ngesikhathi esifanayo, ukusebenza kahle kokushisa okuphansi kwenza amandla abe buthaka ngqo.
I-thermostat ivaliwe (ukushisa kakhulu kwenjini)
Ingozi ephezulu yokulimala kwenjini: I-coolant ayikwazi ukungena ekujikelezeni okukhulu kokushisa, futhi ukushisa kuyaqoqana, okungabangela ukuthi injini "ibile" (i-coolant iyabila) futhi kuholele ekulimaleni kwe-gasket yesilinda, ukudonsa kwe-piston, ngisho nokwehluleka kwenjini.
Ukulahleka kwamandla nokukhishwa kwamandla: Ukushisa ngokweqile kungabangela ukusebenza okungajwayelekile kwezingxenye ezifana nama-valve, ukunciphisa ukuphuma kwamandla; ngesikhathi esifanayo, izinga lokushisa eliphezulu lingabangela ukuthi imishini yokulawula ukukhishwa kwamandla njenge-catalytic converter enezindlela ezintathu yehluleke, okuholela ekukhishweni okukhulu kokukhishwa kwamandla.
Umonakalo ohlobene nochungechunge lwesistimu: Ukushisa okuphezulu okuqhubekayo nakho kulimaza uhlelo lukaphethiloli, uhlelo lokuthambisa, njll., okwandisa kakhulu izindleko zokulungisa kanye nobunzima obulandelayo.
Izindlela zokuhlonza amaphutha
Ngaphezu kokubuka ukufundwa okungajwayelekile kugeji yokushisa kwamanzi (izinga lokushisa eliphansi lesikhathi eside noma ukukhuphuka okusheshayo emgqeni obomvu), izindlela ezilandelayo zingasetshenziswa ukunquma kusengaphambili:
Thinta umehluko wokushisa kwamapayipi amanzi e-radiator: imizuzu emi-3-5 ngemuva kokuqalisa injini ebandayo, thinta amapayipi amanzi aphezulu naphansi e-radiator. Ngaphansi kwezimo ezijwayelekile, ipayipi eliphezulu lishisa kuqala, kanti ipayipi eliphansi lishisa kamuva. Uma amazinga okushisa amapayipi womabili ehlala efana noma umehluko wokushisa mkhulu kakhulu (ngaphezu kuka-15℃), i-thermostat ingase ibe nephutha.
Naka izinguquko ekusetshenzisweni komoya oshisayo kanye nophethiloli: Uma umoya oshisayo ungashisi isikhathi eside ebusika, noma uma ukusetshenziswa kukaphethiloli kukhuphuka ngokuzumayo ngo-5%-10% muva nje, kuhambisana nokungenzi lutho okungazinzile, lokhu kungasetshenziswa njengezinkomba ezisizayo zokwahlulela.
Lalela imisindo engavamile: Kungase kube nomsindo "wokubhonga" noma umsindo wokungqubuzana kwensimbi lapho i-coolant ijikeleza.
Izincomo zokulungisa nokulungisa
Umthelela wokwehluleka kwe-thermostat uyaqhubeka futhi uhlobene, kusukela ekwehleni kokusebenza kuya ekulimaleni kwengxenye eyinhloko. Ngakho-ke:
Ukuhlolwa kanye nokufakwa esikhundleni ngesikhathi: Uma izimpawu ezingenhla sezitholiwe, ukuhlolwa kufanele kwenziwe ngokushesha okukhulu. Izindleko zokushintsha i-thermostat ngokwayo ngokuvamile aziphezulu, kodwa ukulibazisa ukulungiswa kungaholela ekulungisweni okukhulu kwenjini, okubiza kakhulu.
Yenza ukuhlolwa kokuvimbela: Kunconywa ukwenza ukuhlolwa okukhethekile kwesistimu yokupholisa kanye ne-thermostat lapho imoto isihambe amakhilomitha angu-8-100,000 ukuvimbela izinkinga ngaphambi kokuba zenzeke.
Ungayisusi wena ngokwakho: Ukususa i-thermostat kuzokwenza izinga lokushisa lenjini lilahlekelwe ngokuphelele (lilahlekelwe ukulawula), kanye nokufudumala kancane ekuqaleni okubandayo futhi kuthambekele ekushiseni kakhulu emazingeni okushisa aphezulu, okuzokwenza kube kubi kakhulu ukusetshenziswa kukaphethiloli, ukulahlekelwa amandla kanye nokuguguleka kwenjini, futhi kufinyeze kakhulu isikhathi sokuphila kwenjini. Lapho izinga lokushisa likhuphuka (izinga lokushisa lamanzi lingaphezu kuka-85℃): I-wax ngaphakathi kwe-thermostat core iyancibilika ngenxa yokushisa, okubangela ukwanda okukhulu kwevolumu. Lokhu kusunduza ithubhu yerabha kanye nenduku yokucindezela, kunqobe amandla entwasahlobo, futhi kancane kancane kuvuleke ivalvu eholela ku-radiator. I-coolant bese iqala ukugeleza nge-radiator ukuze "kujikeleze kakhulu", ivimbele injini ekushiseni kakhulu.
Emazingeni okushisa ajwayelekile okusebenza (85–95℃): I-thermostat core ilungisa ngokuzenzakalelayo ukuvulwa kwevalvu ngokusekelwe ekushiseni kwamanzi kwesikhathi sangempela, ifinyelele ibhalansi eguquguqukayo phakathi kokujikeleza okukhulu nokuncane, futhi igcine izinga lokushisa lenjini lizinzile.
Ingqikithi ye-thermostat ivame ukuba yisakhiwo "sohlobo lwe-wax", esine-wax egcwaliswe ngaphakathi equkethe i-copper powder. I-copper powder ingahambisa ukushisa ngokushesha, ithuthukise isivinini sokuphendula kokuzwa kokushisa. Isimo sayo sokusebenza sinquma ngqo ukusebenza kahle kokuphathwa kokushisa kwenjini. Uma kukhona amaphutha "ahlala evuliwe" noma "ahlala evaliwe", kungaholela ekushiseni kancane, umoya ofudumele onganele, ukusetshenziswa kukaphethiloli okwandisiwe, noma ukushisa ngokweqile kwenjini, njll., okuyizinkinga ezinkulu.
