Iyini ikhava ye-thermostat yemoto
Isembozo se-thermostat semoto siyidivayisi ye-valve elawula indlela yokugeleza kwe-coolant. Ilawula ngokuzenzakalelayo indlela ye-coolant eya ku-radiator noma enjinini ngokusebenzisa ingxenye ezwa izinga lokushisa ukuqinisekisa ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele.
Umsebenzi oyinhloko
Isembozo se-thermostat sivula noma sivala ngokuzenzakalelayo indlela yokujikeleza kwe-coolant ngokusekelwe ekushiseni kwe-coolant. Uma izinga lokushisa lamanzi liphansi, livala indlela eya ku-radiator, okuvumela i-coolant ukuthi ijikeleze ngaphakathi kwenjini ukuze ishise ngokushesha. Uma izinga lokushisa lamanzi lifinyelela cishe ku-85℃, vula kancane kancane isiteshi ukuze ufinyelele ukujikeleza okubanzi futhi ugcine izinga lokushisa lokusebenza elifanele kakhulu lenjini.
Izici zesakhiwo
Izinto zokuzwa izinga lokushisa zezinto zeparafini zivame ukusetshenziswa. Emazingeni okushisa aphansi, iparafini ihlala iqinile futhi ivala isiteshi; emazingeni okushisa aphezulu, iyancibilika futhi ivule isiteshi. Kwamanye amamodeli, isembozo se-thermostat sihlanganiswe ekuhlanganisweni kwe-thermostat futhi silinganisela izinga lokushisa lenjini ngokulawula ukugeleza kwe-coolant.
Umsebenzi wesembozo se-thermostat yemoto (okungukuthi, i-thermostat) ukulungisa ngokuzenzakalelayo indlela yokujikeleza kohlelo lokupholisa ngokwezinga lokushisa le-coolant, ukuqinisekisa ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele. Imisebenzi ethile yile elandelayo.
Ukulawulwa kwezinga lokushisa
Ukuqina kokushabalalisa ukushisa kungalungiswa ngokulawula ukugeleza kwe-coolant kuya ku-radiator noma ngokuyijikelezisa ngqo emuva enjinini. Uma izinga lokushisa liphansi, vala i-valve. I-coolant ijikeleza isikhashana ngaphakathi kwenjini, okwenza ishise ngokushesha. Ngemva kokufinyelela izinga lokushisa lokusebenza, vula i-valve ukuze ungene ekujikelezeni okukhulu kwe-radiator ukuze kushabalaliswe ukushisa.
Vikela injini
Vimbela izinga lokushisa lamanzi ukuthi lingabi phezulu kakhulu noma liphansi kakhulu
Uma izinga lokushisa lamanzi liphansi, nciphisa ukushabalaliswa kokushisa ukuze uvimbele injini ekubeni ibande kakhulu ngesikhathi sokuqala kokubanda.
Uma izinga lokushisa lamanzi liphezulu, khulisa ukushabalaliswa kokushisa ukuze uvimbele injini ekushiseni ngokweqile.
Thuthukisa ukusebenza kahle
Ukulawula izinga lokushisa okunembile kungenza ngcono ukonga uphethiloli futhi kwandise impilo yenjini, kugweme ukuwohloka kokusebenza kanye nokuguguleka okubangelwa ukushisa ngokweqile noma ukupholisa ngokweqile.
Uma i-thermostat yonakele, izobangela izinga lokushisa lamanzi elingajwayelekile (njengejubane elijwayelekile lokungenzi lutho kodwa izinga lokushisa lamanzi lehla ngesivinini esiphezulu, izinga lokushisa lamanzi eliphezulu endaweni enezinga lokushisa eliphezulu, njll.), futhi idinga ukulungiswa ngesikhathi.
Ukungasebenzi kahle kwesembozo se-thermostat yemoto (okungukuthi, isilawuli sokushisa) kungaholela ohlelweni lokupholisa olungajwayelekile, olubonakala kakhulu njengezimpawu ezilandelayo:
Umlandeli kagesi ongajwayelekile
Ifeni ye-Youdaoplaceholder0 ayiqali : Lapho i-coolant ifinyelela izinga lokushisa elibekiwe, i-thermostat yehluleka ukwenza ifeni ye-elekthronikhi isebenze, okuholela ekushabalaleni kokushisa okunganele.
I-Youdaoplaceholder0 Ifeni iyaqhubeka nokusebenza : Uma i-coolant ingakafiki ezingeni lokushisa elidingekayo, i-thermostat ngephutha ibangela ukuthi ifeni iqhubeke isebenza, okunciphisa amandla ebhethri.
Ukushisa ngokweqile kwenjini
Ukwenyuka kwezinga lokushisa lamanzi kwe-Youdaoplaceholder0: I-coolant ayikwazi ukuqeda ukushisa ngempumelelo, futhi izinga lokushisa lamanzi liyaqhubeka likhuphuka, okungase kubangele ukudonsa kwesilinda, ukuguqulwa kwekhanda lesilinda, noma ngisho nokuma kwenjini.
Ukwehla kwamandla e-Youdaoplaceholder0: Amazinga okushisa aphezulu abangela ukuthi amandla enjini abe buthaka, futhi imisindo yokungqongqoza yensimbi ingase ivele ngesikhathi sokusheshisa.
Ezinye izinto ezingavamile
Isibani sesexwayiso sokushisa kwamanzi esingaguquki se-Youdaoplaceholder0 : I-ECU ayikwazi ukuthola izimpawu zokushisa ezinembile, okubangela indlela yokuvikela ukuphoqa ukushabalaliswa kokushisa.
I-Youdaoplaceholder0 Ukushabalaliswa kokushisa okungavamile : Ukwehluleka kwe-thermostat kungabangela ukuvaleka kokujikeleza kwegazi okukhulu kanye nokubonakaliswa okungavamile kwesilinganiso sokushisa kwamanzi (njengesilinganiso sokushisa kwamanzi esibonisa ukushisa okuphezulu isikhathi eside).
Kunconywa ukuhlola isimo sesilawuli sokushisa ngesikhathi esifanele ukuze kugwenywe ukungasebenzi kahle okukhulu okubangelwa izinkinga zokushabalaliswa kokushisa.
I-thermostat, eyaziwa nangokuthi isilawuli sokushisa, iyivalvu elawula indlela yokugeleza kwe-coolant. Njengedivayisi yokulawula ukushisa okuzenzakalelayo, imvamisa iqukethe ingxenye ezwa ukushisa evula noma ivale ukugeleza komoya, igesi noma uketshezi ngokwandisa noma ukufinyela. Umsebenzi wayo usekelwe enjinini.
Izinga lokushisa lamanzi okupholisa lilungiswa ngokuzenzakalelayo ukuze kulawulwe inani lamanzi angena ku-radiator, kushintshwe ububanzi bokujikeleza kwamanzi ukuze kulungiswe amandla okushisa ohlelweni lokupholisa futhi kuqinisekiswe ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele.
Njengengxenye eyinhloko yesistimu yokupholisa injini yokushisa yangaphakathi, i-thermostat ayiqinisekisi nje kuphela ukusebenza okuvamile kwenjini yokushisa yangaphakathi kodwa futhi inomthelela omkhulu ekongeni uphethiloli wayo, ukukhishwa kwegesi kanye nezinye izici zokusebenza. Intuthuko yayo iye yaziswa kakhulu yimboni yezimoto.
I-thermostat ilungisa ngokuzenzakalelayo inani lamanzi angena ku-radiator ngokusekelwe ekushiseni kwamanzi apholile, ishintsha ububanzi bokujikeleza kwamanzi ukuze ilawule amandla okushisa ohlelweni lokupholisa futhi iqinisekise ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele. I-thermostat kumele igcinwe isesimweni esihle sobuchwepheshe; ngaphandle kwalokho, izothinta kakhulu ukusebenza okuvamile kwenjini. Uma i-valve eyinhloko ye-thermostat ivuleka sekwephuzile, izobangela ukuba injini ishise ngokweqile. Uma i-valve eyinhloko ivulwa kusenesikhathi, isikhathi sokushisa kwangaphambili senjini sizokwelulwa, okubangela ukuthi izinga lokushisa lenjini libe phansi kakhulu.
I-thermostat kumele igcinwe isesimweni esihle sobuchwepheshe; ngaphandle kwalokho, izothinta kakhulu ukusebenza okuvamile kwenjini. Uma ivalvu eyinhloko ye-thermostat ivuleka sekwephuzile, izobangela ukuthi injini ishise ngokweqile. Uma ivalvu eyinhloko ivulwa kusenesikhathi, isikhathi sokushisa injini sizokwelulwa, okubangela ukuthi izinga lokushisa lenjini libe phansi kakhulu. Kuleli qophelo, kunganqunywa ukuthi isimo sokusebenza se-thermostat sihle yini: lapho injini iqala ukubanda, uma kusenamanzi okupholisa aphuma epayipini lokungena kwamanzi legumbi lamanzi elingaphezulu le-radiator, kusho ukuthi ivalvu eyinhloko ye-thermostat ayikwazi ukuvalwa. Uma izinga lokushisa lamanzi okupholisa enjini lidlula u-70℃ futhi kungekho manzi okupholisa aphuma epayipini lokungena kwamanzi legumbi lamanzi elingaphezulu le-radiator, kusho ukuthi ivalvu eyinhloko ye-thermostat ayikwazi ukuvula ngokujwayelekile. Ngalesi sikhathi, kudingeka ukulungiswa.
