Yintoni eyona nto iphambili kwi-thermostat yemoto
Umbindi we-thermostat yemoto, ekwaziwa ngokuba yinto evavanya ubushushu okanye umbindi we-thermal, yinxalenye engundoqo ngaphakathi kwe-thermostat. Inoxanduva lokuva ubushushu be-coolant kunye nokuqhuba ivalvu ukuba ivuleke kwaye ivale, ngaloo ndlela ilungisa ngokuzenzekelayo indlela yokujikeleza kwe-coolant.
Ulwakhiwo kunye nomgaqo wokusebenza kwe-thermostat core kusekelwe kumgaqo wokwandiswa kobushushu kunye nokucutheka. Ingaphakathi layo le-Youdaoplaceholder1 lidla ngokuzaliswa yi-paraffin (ngamanye amaxesha umgubo wobhedu uyongezwa ukuphucula ukuhanjiswa kobushushu). Xa ubushushu be-coolant buphantsi, i-paraffin ikwimeko eqinileyo, i-valve ihlala ivaliwe phantsi kwesenzo sentwasahlobo, kwaye i-coolant ifudumeza ngokukhawuleza injini ngokujikeleza okuncinci (kuhamba ngaphakathi kwenjini kuphela). Xa ubushushu bunyuka bufikelela kumda othile (ngesiqhelo yi-75°C ukuya kwi-105°C, amaxabiso aqhelekileyo aquka i-82°C ukuya kwi-88°C), i-paraffin iyanyibilika kwaye yande, ityhala i-metal push rod okanye i-valve disc ukuvula i-valve, ivumela i-coolant ukuba ingene kwi-radiator ukuze kujikeleze kakhulu ukuphucula ukusasazwa kobushushu.
Ukusebenza kwe-thermostat core kuchaphazela ngokuthe ngqo ubushushu bokusebenza kwenjini. Ukuba iyasilela (njengokulahleka kweparafini okanye ukuwohloka), inokubangela ukuba ivalvu ingavuleki okanye ivale ngokuqhelekileyo, nto leyo ekhokelela kwiingxaki ezifana nokushisa kakhulu kwenjini okanye ixesha elide lokufudumeza kwangaphambili. Iithermostat ze-elektroniki zanamhlanje zithatha indawo yeparafini ngezinto zokufudumeza zombane ukuze kufezekiswe ulawulo oluchanekileyo lobushushu.
Umbindi we-thermostat yemoto (edla ngokubhekisa kwinto ejonga ubushushu kwi-thermostat, njenge-capsule yeparafini) yinxalenye ephambili ye-thermostat. Umsebenzi wayo kukulawula ngokuzenzekelayo ukuvulwa/ukuvalwa kwendlela yokujikeleza kwe-coolant ngokusekelwe kutshintsho lobushushu be-coolant, ngaloo ndlela ilawula amandla okusasaza ubushushu benjini kunye nokuqinisekisa ukuba injini isebenza ngaphakathi koluhlu lobushushu olufanelekileyo (ngesiqhelo i-80-95℃).
Isiseko se-thermostat sifezekisa ulawulo oluzenzekelayo ngeempawu zomzimba zezinto ezivavanya ubushushu: xa injini iqaliswa ukubanda, ubushushu be-coolant buphantsi, kwaye into evavanya ubushushu (njengeparafini) ikwimeko eqinileyo, ityhala ivalvu ukuba ivale indlela eya kwi-radiator, ivumela i-coolant ukuba ijikeleze ngaphakathi kwenjini ixesha elincinci, inyusa ubushushu ngokukhawuleza. Xa i-coolant ifikelela kwixabiso elimiselweyo (elifana ne-80℃), into evavanya ubushushu iyanyibilika kwaye yande ngenxa yobushushu, icinezela ipayipi yerabha okanye intonga yokutyhala ukuvula ivalvu. I-coolant emva koko idlula kwi-radiator ukuze ukujikeleza okukhulu kuphole, ithintele injini ekubeni itshise kakhulu.
I-Youdaoplaceholder0 le nkqubo yokulawula ngokuzenzekelayo inempembelelo ebalulekileyo ekusebenzeni kwenjini:
I-Youdaoplaceholder0 Yonyusa ukusebenza kakuhle kunye nokonga: Xa injini isebenza kubushushu obufanelekileyo, ipetroli itsha ngokupheleleyo, inciphisa ukusetyenziswa kwepetroli nge-10% ukuya kwi-15%, kwaye inciphisa ukukhukuliseka kweendonga zesilinda yi-carbon deposits kunye nepetroli engatshanga.
I-Youdaoplaceholder0 Nciphisa ukuguguleka kwaye wandise ubomi benkonzo : Kuphephe ukwanda kokumelana nokungqubana okubangelwa kukwanda kwe-oyile yokuthambisa kumaqondo obushushu aphantsi, kwaye unciphise ukuguguleka kwezinto ezifana nee-crankshafts kunye nee-bearing shells.
I-Youdaoplaceholder0 Umbane ozinzileyo: Thintela i-atomization embi yepetroli xa ubushushu buphantsi kakhulu ukuqinisekisa amandla agudileyo.
Ukuthembeka kwesiseko se-thermostat kunxulumene ngokuthe ngqo nokuzinza kwenkqubo yolawulo lobushushu. Ukuba ayisebenzi kakuhle, inokubangela ukuba injini ihlale kubushushu obuphantsi okanye ifudumale kakhulu ixesha elide, nto leyo ebangela ukuba ukusetyenziswa kwepetroli kunye neengxaki zokuguguleka kube nzima.
I-thermostat core yinxalenye ebalulekileyo kwinkqubo yokupholisa iimoto, enoxanduva lokulungisa ngokuzenzekelayo indlela yokujikeleza kwe-coolant ngokusekelwe kubushushu benjini ukugcina injini ikwiqondo lobushushu elifanelekileyo lokusebenza (ngesiqhelo i-80-90℃).

Ukungasebenzi kakuhle kwayo kuya kubangela uthotho lweengxaki zetsheyini, nto leyo echaphazela ukusebenza kwayo kunye nobomi bayo bonke.
Izizathu eziphambili zokusilela kwe-thermostat core ziquka: ubushushu bokuvula kwevalvu buphezulu kakhulu okanye abunakuvulwa, nto leyo ekhokelela ekubeni i-coolant ingakwazi ukugqiba ukujikeleza okukhulu kwaye ibangele ukuba injini ifudumale kakhulu; Ukuba ayivalwanga kakuhle, injini iya kufudumala kancinci okanye ibande kakhulu. Ukusetyenziswa kwexesha elide kwe-coolant engcolileyo kunokukhokelela ekuboleni kwevalvu, ukuqokelelana kwezikali okanye ukuvaleka kokungcola. Ukuvuza kwengxowa yewax ejonga ubushushu bangaphakathi, ukungasebenzi kwentwasahlobo okanye umhlwa kunye nokunamathela nako kunokuphazamisa ukusebenza kwayo okuqhelekileyo.
Iimpawu eziphambili zesifo sentliziyo zezi:
I-Youdaoplaceholder0 Ubushushu bamanzi obungaqhelekanga : Xa i-thermostat ibambeka ize ivale, injini idla ngokushushu kakhulu kwaye isibane se-alamu yobushushu bamanzi siya kuvula. Ukuba ivalvu ephambili ayivali kakuhle, ubushushu bamanzi buya kunyuka kancinci kwaye injini iya kusebenza kubushushu obuphantsi ixesha elide.
Ukwehla kokusetyenziswa kwepetroli kunye nokusebenza kwayo: Ukushushu kakhulu kunye nokuphola kakhulu kunokunciphisa ukusebenza kakuhle kokutsha, kwandise ukusetyenziswa kwepetroli, kwaye kunokubangela iidiphozithi zekhabhoni ngenxa yokutsha okungaphelelanga kwepetroli, okukhokelela ekushukumeni kwenjini, amandla anciphileyo okanye ubunzima ekuqaliseni.
I-Youdaoplaceholder0 Inkqubo yokupholisa engaqhelekanga : Ifeni isenokungaqali njengoko kufuneka, okanye ukujikeleza kwamanzi akuzinzanga, umzekelo, kukho amanzi ahamba kwipayipi yokungena kwangethuba kakhulu ngexesha lokubanda okanye amanzi angabikho emva kobushushu obuphezulu.
I-Youdaoplaceholder0 Ezi ndlela zilandelayo zingasetyenziselwa ukufumanisa ingxaki ye-thermostat core:
Uvavanyo lwe-Youdaoplaceholder0 Feel : Emva kokuqalisa injini, chukumisa imibhobho yamanzi ephezulu nesezantsi yerediyetha malunga nemizuzu emi-3. Kwiimeko eziqhelekileyo, umbhobho ophezulu ushushu kwaye umbhobho osezantsi upholile. Ukuba umahluko wobushushu phakathi kwezi zimbini mncinci okanye zishushu ngaxeshanye, ukungasebenzi kakuhle kunokwenzeka.
Ukujonga ukuhamba kwamanzi e-Youdaoplaceholder0: Xa uqala ukubanda, jonga umbhobho wokungena kwamanzi kwitanki yamanzi. Ukuba kukho ukuhamba kwamanzi okuqhubekayo xa ubushushu bamanzi bungaphantsi kwama-70℃, oko kubonisa ukuba ivalvu ephambili ayivalwanga kakuhle. Ukuba akusekho ukuhamba kwamanzi emva kokuba ubushushu bamanzi budlule kuma-90℃, isenokunamathela ize ivalwe.
Umlinganiselo wobushushu be-infrared ye-Youdaoplaceholder0 : Linganisa ubushushu bamanzi okungena kunye namanzi aphumayo kwi-thermostat. Kwiimeko eziqhelekileyo, xa ubushushu bamanzi bufikelela malunga ne-70℃, ubushushu bamanzi aphumayo kufuneka bunyuke ngequbuliso. Ukuba umahluko wobushushu uhlala mkhulu okanye awutshintshi kwaphela, unokungaphumeleli.
Uvavanyo lokuqhaqha kunye nokufudumeza lwe-Youdaoplaceholder0: Faka i-thermostat emanzini ukuze ifudumale. Ifanele ivulwe kwi-75℃, kwaye ilifti kufuneka ibe ngaphezulu kwe-8.5mm kwi-93℃; kungenjalo, kufuneka itshintshwe.
Ukuphathwa kwe-Youdaoplaceholder0 kunye namanyathelo okuthintela aquka: Ukuba ingxaki iqinisekisiwe, i-thermostat kufuneka itshintshwe ngexesha. Ixabiso kwivenkile yokulungisa eqhelekileyo limalunga ne-100 ukuya kwi-300 yuan, ngelixa ixabiso kwivenkile ye-4S liphezulu. Emva kokutshintshwa, qiniseka ukuba ukhupha wonke umoya kwinkqubo yokupholisa kwaye ujonge umgangatho we-coolant. Ukuba imdaka okanye inezingcola ezininzi, kufuneka itshintshwe ngaxeshanye. Ngexesha lokugcinwa kwemihla ngemihla, ukujonga rhoqo inqanaba le-coolant, indawo yokukhenkceza kunye nococeko, kunye nokusebenzisa i-antifreeze efanelekileyo kunokunciphisa amathuba okusilela kwe-thermostat.
