Umsebenzi we-thermostat yemoto
Umsebenzi oyinhloko we-thermostat yemoto ukulungisa ngokuzenzakalelayo indlela yokujikeleza kwe-coolant ngokusekelwe ekushiseni kwenjini, ukuqinisekisa ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele.
Ukushisa okusheshayo: Uma injini iqaliswa ngokubandayo, i-thermostat ivala indlela eya ku-radiator, bese i-coolant ijikeleza ngaphakathi kwenjini kuphela (ukujikeleza okuncane), okusiza injini ukuthi ifinyelele ngokushesha izinga lokushisa elijwayelekile lokusebenza.
Ukuvimbela ukushisa ngokweqile: Lapho izinga lokushisa lenjini likhuphuka, i-thermostat iyavuleka, bese i-coolant igeleza nge-radiator ukuze kujikeleze kakhulu, ichithe ukushisa ngesikhathi ukuvimbela injini ekushiseni ngokweqile.
Ukwenza ngcono ukusebenza: Ngokulondoloza izinga lokushisa elifanele, i-thermostat isiza ekuthuthukiseni ukonga uphethiloli, ukunciphisa ukuguguleka, nokwandisa isikhathi sokuphila kwenjini.
I-thermostat yemoto eyonakele ingabangela ukuthi izinga lokushisa lenjini lingalawuleki. Ikakhulukazi, kubonakala njengokushisa ngokweqile kwenjini noma ukwehluleka ukufinyelela izinga lokushisa lokusebenza elijwayelekile, ngaleyo ndlela kubangele uchungechunge lwezinkinga zokusebenza nokuqina.
Umthelela oyinhloko kanye nokubonakaliswa okuthile
Umonakalo we-thermostat ungahlukaniswa ngezimo ezimbili: ukubhajwa endaweni evulekile ngokuphelele noma ukubhajwa endaweni evaliwe ngokuphelele. Imiphumela emotweni ihluke ngokuphelele.
I-thermostat ivuliwe ngokuphelele (injini ayikwazi ukufudumala)
Ukusetshenziswa kukaphethiloli kuyanda kakhulu: Uma injini isebenza ezingeni lokushisa eliphansi isikhathi eside, uphethiloli awushintshi kahle, futhi ikhompyutha izokwandisa ivolumu yokufaka uphethiloli ukuze iqhubeke isebenza. Ukusetshenziswa kukaphethiloli kunganda ngo-10%-15%.
Ukwehluleka kohlelo lokufudumala nokufudumala noma ukusebenza okubi kakhulu: Njengoba ukushisa kuqhubeka nokushabalala ekujikelezeni okukhulu kwe-coolant, izinga lokushisa lomoya lohlelo lokufudumala liphansi, 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, okusheshisa ukuguguleka futhi okuholela ekungakhiqizi kahle kwamandla. Ngesikhathi esifanayo, ukusebenza kahle kokushisa okuphansi nakho kwenza amandla abe buthaka ngqo.
I-thermostat ivaliwe ngokuphelele (ukushisa kakhulu kwenjini)
Ingozi ephezulu yokulimala kwenjini: I-coolant ayikwazi ukungena ekujikelezeni okukhulu kokushisa, futhi ukushisa kuyaqoqana, okwenza injini "ibile" kalula (i-coolant ibila), okungase kuholele ekulimaleni kwe-cylinder liner, ekudonsweni kwe-piston, ngisho nasenjinini.
Ukulahlekelwa amandla nokukhishwa komoya: Ukushisa ngokweqile kungabangela ukuthi izingxenye ezifana nama-valve zibambeke, okuholela ekusebenzeni okungajwayelekile; ngesikhathi esifanayo, izinga lokushisa eliphezulu lingabangela ukuthi amadivayisi okulawula ukukhishwa komoya asebenze njenge-catalytic converter enezindlela ezintathu ahluleke, okuholela ekukhishweni komoya okweqile.
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: Ngemva kokuba injini iqalile imizuzu emi-3-5, thinta amapayipi amanzi aphezulu nangaphansi e-radiator. Ngaphansi kwezimo ezivamile, ipayipi eliphezulu lishisa kakhulu kuqala, kanti ipayipi eliphansi lishisa kakhulu kamuva. Uma amazinga okushisa amapayipi womabili ehlala efana noma umehluko wokushisa mkhulu kakhulu (ngaphezu kuka-15°C), i-thermostat ingase ibe nephutha.
Qaphela izinguquko ekushiseni nasekusetshenzisweni kukaphethiloli: Uma uhlelo lokushisa lungashisi isikhathi eside ebusika, noma ukusetshenziswa kukaphethiloli kukhuphuka ngokuzumayo ngo-5%-10% muva nje, kuhambisana nokungahlaliseki kahle, lungasetshenziswa njengesiqondiso esiwusizo sokwahlulela.
Lalela imisindo engavamile: Kungase kube nomsindo "wokubhodla" noma umsindo wokungqubuzana kwensimbi ngesikhathi sokujikeleza kwe-coolant.
Izincomo zokulungisa nokulungisa
Umthelela wokwehluleka kwe-thermostat unemiphumela eqhubekayo nehlobene, kusukela ekwehleni kokusebenza kuya ekulimaleni kwengxenye eyinhloko. Ngakho-ke:
Ukuhlolwa kanye nokufakwa kwenjini ngesikhathi esifanele: Uma izimpawu ezingenhla seziqashelwe, kubalulekile ukuhlola ngokushesha. Izindleko zokufakwa kwe-thermostat ngokwayo ngokuvamile aziphezulu, kodwa ukubambezeleka kokulungiswa kungaholela ekulungisweni okukhulu kwenjini, okuholela ezindlekweni ezinkulu.
Yenza ukuhlolwa kokuvimbela: Kunconywa ukuthi kwenziwe ukuhlolwa okukhethekile kwesistimu yokupholisa kanye ne-thermostat lapho imoto isihambe amakhilomitha angu-8-100,000 ukuvimbela izinkinga ngaphambi kokuba zenzeke. Ungazami ukuzisusa wena: Ukususa i-thermostat kuzokwenza ukuthi izinga lokushisa lenjini lilahlekelwe ngokuphelele ukulawula. Ukuqala okubandayo kuzophuza kakhulu ukufudumala, futhi emazingeni okushisa aphezulu, kuthambekele ekushiseni ngokweqile, okuzokwandisa kakhulu ukusetshenziswa kukaphethiloli, ukulahlekelwa amandla kanye nokuguguleka kwenjini, futhi kufinyeze kakhulu isikhathi sokuphila kwenjini.
