I-thermostat yemoto.
Isenzo semveliso
I-thermostat kufuneka igcinwe ikwimeko entle yokusebenza, kungenjalo iya kuchaphazela kakhulu ukusebenza kwesiqhelo kwenjini. Ukuba i-thermostat ivula (nantsi ivalvu ephambili ye-thermostat ye-knuckle) sele ivukile okanye ayikwazi ukuvula, iya kubangela ukuba injini ishushu kakhulu; Ivuleke kwangethuba kakhulu, ixesha lokufudumeza injini liyandiswa, ukuze ubushushu benjini bube phantsi kakhulu.
Umgaqo wokusebenza
I-Thermostat (i-Thermostat) luhlobo lwesixhobo sokulawula ubushushu ngokuzenzekelayo, esihlala siqulathe izinto ezibonisa ubushushu, ngokwandisa okanye ukucutha ukuvula, ukucima ukuhamba kwe-coolant, oko kukuthi, ngokweqondo lobushushu lolwelo lokupholisa, ngokuzenzekelayo uhlengahlengisa amanzi kwi-radiator, utshintshe uluhlu lokujikeleza kwe-coolant, ukuze ulungelelanise amandla okupholisa enkqubo yokupholisa.
I-thermostat esetyenziswa yinjini ikakhulu yi-thermostat ye-wax, elawulwa yi-paraffin wax ngaphakathi kokujikeleza kwe-coolant ngomgaqo wokwandiswa kobushushu kunye nokucotha kokubanda. Xa ubushushu bokupholisa buphantsi kunexabiso elichaziweyo, i-paraffin ecociweyo emzimbeni oqonda ubushushu we-thermostat iqinile, ivalvu ye-thermostat ivala umjelo phakathi kwenjini kunye ne-radiator phantsi kwesenzo sentwasahlobo, kwaye i-coolant ibuyela enjinini ngepompo yamanzi ukuze ijikeleze kancinci enjinini. Xa ubushushu be-coolant bufikelela kwixabiso elichaziweyo, i-paraffin iqala ukunyibilika kwaye kancinci kancinci ibe lulwelo, umthamo uyanda kwaye ucinezele ityhubhu yerabha ukuze inciphe, ngelixa ityhubhu yerabha incipha, intonga yokutyhala isebenza ekutyhaleni phezulu, kwaye intonga yokutyhala ine-downward reverse thrust kwivalvu ukuvula ivalvu. Ngeli xesha, i-coolant idlula kwi-radiator kunye nevalvu ye-thermostat, ize ibuyele enjinini ngepompo ukuze ijikeleze kakhulu. Uninzi lwe-thermostat lucwangciswe kumbhobho we-cylinder head outlet, onenzuzo yesakhiwo esilula kunye nokukhupha amaqamza ngokulula kwinkqubo yokupholisa; Ingxaki kukuba i-thermostat idla ngokuvula ivaleke xa isebenza, nto leyo ebangela ukushukuma.
Xa ubushushu bokusebenza kwenjini buphantsi (ngaphantsi kwama-70°C), i-thermostat ivala ngokuzenzekelayo indlela eya kwi-radiator, ize ivule indlela eya kwi-pump, amanzi okupholisa aphuma kwi-jacket ngqo nge-hose angene kwi-pump, kwaye i-pump ingene kwi-jacket ukuze ijikeleze, kuba amanzi okupholisa awanyamalali yi-radiator, angenza ubushushu bokusebenza kwenjini bunyuke ngokukhawuleza, le ndlela yomjikelo ibizwa ngokuba yi-small cycle. Xa ubushushu bokusebenza kwenjini buphezulu (80°C nangaphezulu), i-thermostat ivala ngokuzenzekelayo indlela ekhokelela kwi-pump, ize ivule indlela ekhokelela kwi-radiator, amanzi okupholisa aphuma kwi-jacket apholiswa yi-radiator aze athunyelwe kwi-jacket yi-pump, nto leyo ephucula amandla okupholisa ukuthintela injini ekutshiseni kakhulu, le ndlela yomjikelo ibizwa ngokuba yi-large cycle. Xa ubushushu bokusebenza kwenjini buphakathi kwama-70 nama-80°C, imijikelo emikhulu nemincinci ikhona ngaxeshanye, oko kukuthi, inxalenye yamanzi okupholisa ukuze kujikelezwe kakhulu, ngelixa enye inxalenye yamanzi okupholisa ukuze kujikelezwe kancinci.
Indima ye-thermostat yemoto kukuvala ngaphambi kokuba ubushushu bemoto bungafiki kubushushu obuqhelekileyo, kwaye i-coolant yenjini ibuyiselwe enjinini ngepompo yamanzi ukuze yenze ukujikeleza okuncinci kwinjini, ukuze injini ifudumale ngokukhawuleza. Xa ubushushu obuqhelekileyo budlulile, bunokuvulwa ukuvumela i-coolant ukuba ijikeleze kwisekethe yeradiator yetanki yonke ukuze ichithe ubushushu ngokukhawuleza.
Ukuhlolwa kwemveliso
Ubomi obukhuselekileyo be-thermostat ye-wax ngokubanzi yi-50,00km, ngoko ke kufuneka itshintshelwe rhoqo ngokwempilo yayo ekhuselekileyo. Jonga indlela ye-thermostat kwi-thermostat ehlengahlengiswayo yobushushu. Jonga ubushushu bokuvula bevalvu ephambili ye-thermostat, ubushushu obuvulekileyo obupheleleyo kunye nokuphakamisa, enye yazo engafikeleliyo kwixabiso elimiselweyo, kufuneka itshintshwe i-thermostat. Umzekelo, i-thermostat yenjini ye-Santana JV, ubushushu bokuvula bevalvu ephambili yi-87 ° C ngaphezulu okanye ngaphantsi kwe-2 ° C, ubushushu bokuvula obupheleleyo yi-102 ° C ngaphezulu okanye ngaphantsi kwe-3 ° C, kwaye ukuphakamisa okuvulekileyo okupheleleyo yi-> 7mm.
Ingxaki yento
Kwiimeko eziqhelekileyo, xa injini iqala, ubushushu bokusebenza buphantsi kakhulu, ukuze ubushushu bunyuke ngokukhawuleza, emva koko budlule kulawulo lwe-thermostat (ivalvu ephambili ye-thermostat ivaliwe), ukuze i-coolant ephuma kwipompo yolwelo ingene kumbhobho wamanzi, i-coolant ingadluli kwi-radiator, lo ngumjikelo omncinci, xa ubushushu be-coolant bufikelela kuma-degrees angama-87 (ubushushu obuvulekileyo be-thermostat ye-Bora yama-degrees angama-87, Emva koko, ivalvu ye-thermostat iyavuleka, i-coolant iqala ukuhamba kwi-radiator, kwaye inkqubo yokupholisa ingena kumjikelo omkhulu. Ngokubanzi, malunga nemizuzu emihlanu emva kokuba imoto iqalile, ubushushu be-coolant bunokufikelela kubushushu obuqhelekileyo bama-degrees angama-85 ~ 105, ukuba ubushushu obuqhelekileyo bokusebenza abufikelelwanga ixesha elide, okanye ubushushu bunyuke ngaphezu kwama-degrees angama-110, kufuneka kurhanelwe ukuba i-thermostat inesiphako.
