Iyini ingqikithi ye-thermostat yemoto
Ingqikithi ye-thermostat yezimoto, eyaziwa nangokuthi i-element ezwa ukushisa noma i-thermal core, iyi-core component engaphakathi kwe-thermostat. Inesibopho sokuzwa izinga lokushisa le-coolant nokushayela i-valve ukuthi ivuleke futhi ivale, ngaleyo ndlela ilungise ngokuzenzakalelayo indlela yokujikeleza kwe-coolant.
Isakhiwo kanye nesimiso sokusebenza se-thermostat core kusekelwe esimisweni sokwanda nokuncipha kokushisa. Ingaphakathi layo le-Youdaoplaceholder1 livame ukugcwaliswa nge-paraffin (ngezinye izikhathi impuphu yethusi iyengezwa ukuthuthukisa ukuhanjiswa kokushisa). Lapho izinga lokushisa le-coolant liphansi, i-paraffin isesimweni esiqinile, i-valve ihlala ivaliwe ngaphansi kwesenzo sesiphethu, futhi i-coolant ishisa injini ngokushesha ngokujikeleza okuncane (kugeleza ngaphakathi kwenjini kuphela). Lapho izinga lokushisa lenyuka liye emkhawulweni othize (ngokuvamile 75°C kuya ku-105°C, amanani ajwayelekile afaka 82°C kuya ku-88°C), i-paraffin iyancibilika futhi inwebeke, icindezela induku yokucindezela yensimbi noma idiski ye-valve ukuvula i-valve, okuvumela i-coolant ukuthi igeleze ku-radiator ukuze kugeleze kakhulu ukujikeleza ukuze kuthuthukiswe ukushabalaliswa kokushisa.
Ukusebenza kwe-thermostat core kuthinta ngqo izinga lokushisa lokusebenza kwenjini. Uma i-yehluleka (njengokulahlekelwa yi-parafini noma ukuwohloka), kungabangela ukuthi i-valve yehluleke ukuvula noma ukuvala ngokujwayelekile, okuholela ezinkingeni ezifana nokushisa ngokweqile kwenjini noma isikhathi esiningi sokushisa kusengaphambili. Ama-thermostat kagesi esimanje athatha indawo ye-parafini ngezinto zokushisa zikagesi ukuze kufezwe ukulawula izinga lokushisa okunembile.
Ingqikithi ye-thermostat yemoto (ngokuvamile ibhekisela ku-element ezwa ukushisa ku-thermostat, njenge-capsule ye-paraffin) iyinxenye eyinhloko ye-thermostat. Umsebenzi wayo ukulawula ngokuzenzakalelayo ukuvulwa/ukuvalwa kwendlela yokujikeleza kwe-coolant ngokusekelwe ekushintsheni kwezinga lokushisa le-coolant, ngaleyo ndlela ilawula amandla okushisa enjini nokuqinisekisa ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele (ngokuvamile 80-95℃).
I-thermostat core ifinyelela ukulawulwa okuzenzakalelayo ngezakhiwo ezibonakalayo zezinto ezizwa ukushisa: lapho injini iqaliswa kubanda, izinga lokushisa le-coolant liphansi kakhulu, futhi into ezwa ukushisa (njenge-parafini) isesimweni esiqinile, icindezela i-valve ukuthi ivale indlela eya ku-radiator, ivumela i-coolant ukuthi ijikeleze ngaphakathi kwenjini isikhathi esincane, ikhuphule izinga lokushisa ngokushesha. Lapho i-coolant ifinyelela inani elibekiwe (njengama-80℃), into ezwa ukushisa iyancibilika futhi inwebeke ngenxa yokushisa, icindezela ipayipi lerabha noma induku yokucindezela ukuvula i-valve. I-coolant ibe isigeleza nge-radiator ukuze ukujikeleza okukhulu kuphole, ivimbele injini ekushiseni ngokweqile.
I-Youdaoplaceholder0 le nqubo yokulawula okuzenzakalelayo inethonya elibalulekile ekusebenzeni kwenjini:
I-Youdaoplaceholder0 Thuthukisa ukusebenza kahle kanye nokonga : Uma injini isebenza ezingeni lokushisa elifanele, uphethiloli ushisa ngokugcwele, kunciphisa ukusetshenziswa kukaphethiloli ngo-10% kuya ku-15%, futhi kunciphisa ukuguguleka kwezindonga zesilinda ngamadiphozithi ekhabhoni kanye nophethiloli ongashiswanga.
I-Youdaoplaceholder0 Yehlisa ukuguguleka futhi wandise isikhathi senkonzo : Gwema ukwanda kokumelana kokungqubuzana okubangelwa ukwanda kokuthamba kwamafutha emazingeni okushisa aphansi, futhi wehlise ukuguguleka kwezingxenye ezifana nama-crankshaft nama-bearing shells.
I-Youdaoplaceholder0 Ukukhishwa kwamandla okuzinzile : Vimbela i-atomization embi kaphethiloli lapho izinga lokushisa liphansi kakhulu ukuqinisekisa amandla abushelelezi.
Ukuthembeka kwe-thermostat core kuhlobene ngqo nokuqina kwesistimu yokuphatha ukushisa. Uma ingasebenzi kahle, ingabangela ukuthi injini ihlale ekushiseni okuphansi noma ishise ngokweqile isikhathi eside, okwandisa ukusetshenziswa kukaphethiloli nezinkinga zokuguguleka.
I-thermostat core iyisici esibalulekile ohlelweni lokupholisa lwezimoto, esinomthwalo wokulungisa ngokuzenzakalelayo indlela yokujikeleza kwe-coolant ngokusekelwe ekushiseni kwenjini ukuze injini igcine izinga lokushisa lokusebenza elifanele (ngokuvamile 80-90℃).

Ukungasebenzi kahle kwayo kuzobangela uchungechunge lwezinkinga zamaketanga, okuthinta ukusebenza kanye nesikhathi sokuphila kwenjini.
Izimbangela eziyinhloko zokwehluleka kwe-thermostat core zifaka: izinga lokushisa lokuvula kwe-valve liphezulu kakhulu noma alikwazi ukuvulwa, okuholela ekutheni i-coolant ingakwazi ukuqeda ukujikeleza okukhulu futhi kubangele ukuthi injini ishise ngokweqile; Uma ingavalwanga kahle, injini izoshisa kancane noma ibande kakhulu. Ukusetshenziswa kwesikhathi eside kwe-coolant engcolile kungaholela ekugqwaleni kwe-valve, ukuqongelela kwezikali noma ukuvaleka kokungcola. Ukuvuza kwesikhwama se-wax esizwa ukushisa kwangaphakathi, ukwehluleka kwentwasahlobo noma ukugqwala kanye nokunamathela nakho kungaphazamisa ukusebenza kwayo okuvamile.
Izimpawu eziyinhloko zephutha yilezi:
I-Youdaoplaceholder0 Izinga lokushisa lamanzi elingajwayelekile : Lapho i-thermostat ibambeka futhi ivala, injini ithambekele ekushiseni ngokweqile futhi isibani se-alamu sokushisa kwamanzi sizokhanya. Uma i-valve eyinhloko ingavali kahle, izinga lokushisa lamanzi lizokhuphuka kancane futhi injini izosebenza ngezinga lokushisa eliphansi isikhathi eside.
I-Youdaoplaceholder0 Ukusetshenziswa kukaphethiloli kanye nokusebenza kwehla : Kokubili ukushisa ngokweqile kanye nokupholisa ngokweqile kunganciphisa ukusebenza kahle kokushisa, kwandise ukusetshenziswa kukaphethiloli, futhi kungabangela ukufakwa kwekhabhoni ngenxa yokusha okungaphelele kukaphethiloli, okuholela ekunyakazeni kwenjini, amandla anciphile noma ubunzima bokuqala.
I-Youdaoplaceholder0 Uhlelo lokupholisa olungavamile : Ifeni ingase ingaqali njengoba kudingeka, noma ukujikeleza kwamanzi kungazinzile, isibonelo, kukhona amanzi ageleza epayipini lokungenisa kusenesikhathi kakhulu ngesikhathi sokuqala kokubanda noma kungabikho ukugeleza kwamanzi ngemva kokushisa okuphezulu.
I-Youdaoplaceholder0 Izindlela ezilandelayo zingasetshenziswa ukuthola iphutha le-thermostat core:
Isivivinyo sokuzwa se-Youdaoplaceholder0: Ngemva kokuqalisa injini, thinta amapayipi amanzi aphezulu nangaphansi e-radiator cishe imizuzu emi-3. Ngaphansi kwezimo ezivamile, ipayipi eliphezulu liyashisa kanti ipayipi eliphansi lipholile. Uma umehluko wokushisa phakathi kwalokhu okubili umncane noma kushisa ngesikhathi esisodwa, kungase kube nokungasebenzi kahle.
Ukuqapha ukugeleza kwamanzi kwe-Youdaoplaceholder0: Uma uqala ukubanda, qaphela ipayipi lokungena kwamanzi lethangi lamanzi. Uma kukhona ukugeleza kwamanzi okuqhubekayo lapho izinga lokushisa lamanzi lingaphansi kuka-70℃, kusho ukuthi ivalvu eyinhloko ayivaliwe kahle. Uma kusekhona ukugeleza kwamanzi ngemva kokuba izinga lokushisa lamanzi lidlule ku-90℃, lingabhajwa futhi livalwe.
Ukulinganisa izinga lokushisa le-infrared le-Youdaoplaceholder0 : Linganisa izinga lokushisa lamanzi okungena kanye namanzi okukhipha e-thermostat. Ngaphansi kwezimo ezivamile, lapho izinga lokushisa lamanzi lifinyelela cishe ku-70℃, izinga lokushisa lamanzi okukhipha kufanele likhuphuke ngokuzumayo. Uma umehluko wokushisa uhlala mkhulu noma ungashintshi nhlobo, ungase wehluleke.
Ukuhlolwa kokuhlukaniswa nokushisa kwe-Youdaoplaceholder0: Faka i-thermostat emanzini ukuze uyifudumale. Kufanele ivulwe ku-75℃, futhi ilifti kufanele ibe ngaphezu kuka-8.5mm ku-93℃; ngaphandle kwalokho, idinga ukushintshwa.
Izinyathelo zokuphatha kanye nokuvimbela i-Youdaoplaceholder0 zifaka: Uma iphutha liqinisekisiwe, i-thermostat kufanele ishintshwe ngesikhathi. Izindleko esitolo sokulungisa esivamile zingama-yuan ayi-100 kuya kwangu-300, kuyilapho izindleko esitolo se-4S ziphakeme kakhulu. Ngemva kokushintsha, qiniseka ukuthi ukhipha wonke umoya ohlelweni lokupholisa futhi uhlole ikhwalithi ye-coolant. Uma ingcolile noma iqukethe ukungcola okuningi, kufanele ishintshwe ngesikhathi esisodwa. Ngesikhathi sokulungisa nsuku zonke, ukuhlola njalo izinga le-coolant, indawo yokubanda kanye nokuhlanzeka, kanye nokusebenzisa i-antifreeze efanelekile kunganciphisa amathuba okwehluleka kwe-thermostat.
