Umsebenzi wenkqubo yokupholisa imoto kukuphelisa ubushushu be-injini ngexesha, ukuze injini isebenze kowona bushushu ufanelekileyo.Inkqubo efanelekileyo yokupholisa imoto ayifanelanga kuphela ukuhlangabezana neemfuno zokupholisa i-injini, kodwa ikwanciphisa ilahleko yobushushu kunye nokusetyenziswa kwamandla, ukuze injini ibe nesiphumo esingcono sokugcina amandla kwisiseko sokuqinisekisa ukusebenza kakuhle kwamandla.

I. Umgaqo wokusebenza wenkqubo yokupholisa

Isixokelelwano sokupholisa sidlala indima ebaluleke kakhulu kwinqwelo-mafutha, inkqubo yokupholisa i-injini ngokuqhelekileyo yamkela ukupholisa kwamanzi, inkqubo yokupholisa eqhelekileyo yenziwe ngeradiyetha, ithumbu lerediyetha, i-thermostat, impompo yamanzi, ifeni yokupholisa kunye nebhanti lefeni.

Ixhomekeke kwimpompo yamanzi okupholisa aqukuqela kwisipholile se-oyile, ibhatyi yamanzi e-crankcase kunye nentloko ye-cylinder, ithatha ubushushu obugqithileyo be-injini.

Ujikelezo olukhulu: xa i-injini isebenza phantsi kweemeko eziqhelekileyo zobushushu, oko kukuthi, ubushushu bamanzi bungaphezulu kwe-80℃, amanzi okupholisa kufuneka onke aqukuqelele kwiradiyetha ukwenza ujikelezo olukhulu.Ivalve ephambili ye-thermostat ivuleke ngokupheleleyo kwaye ivalve yesibini ivalwe ngokupheleleyo.

Ukujikeleza okuncinci: xa ubushushu bamanzi okupholisa bungaphantsi kwe-70 ℃, uxinzelelo lomphunga kwibhokisi yokwandisa lincinci kakhulu, kwaye amanzi okupholisa awahambi nge-radiator, kodwa aqhuba kuphela ukujikeleza okuncinci phakathi kwebhatyi yamanzi kunye nempompo.

Eyesibini, indima yokupholisa

Isipholisi sidlala indima ebaluleke kakhulu ekusebenzeni okuqhelekileyo kwe-injini.Ubushushu obuphezulu kakhulu okanye obuphantsi kakhulu besipholisi bunokuchaphazela kakubi ukusebenza kwe-injini.Ukuba iqondo lobushushu le-injini yokupholisa liphezulu kakhulu kunye ne-viscosity ye-oyile yokuthambisa iyancipha, ilahleko yokukhuhlana kwamalungu e-injini kuya kwandiswa.

Ukuba iqondo lobushushu le-injini yokupholisa lisezantsi kakhulu, i-viscosity ye-oyile yokuthambisa iyenyuka kwaye ulwelo luba mbi, nto leyo engakwaziyo ukuthambisa, oko kucutha ukuphuma kwamandla e-injini kwaye kuchaphazele ukusebenza ngoomatshini be-injini.

I-Coolant yindawo yokudlulisa ubushushu kwinkqubo yokupholisa, kunye nokupholisa, ukuchasana nokubola, ukuchasana nokulinganisa kunye nokuchasana nokukhenkceza kunye neminye imisebenzi, iqulunqwe ngamanzi, i-antifreeze kunye nezongezo ezahlukeneyo.

1. Amanzi yinxalenye ebalulekileyo yesipholisi.Inomthamo omkhulu wobushushu obuthile kunye nokuhanjiswa kobushushu okukhawulezayo, kwaye ubushushu obufunxwa ngamanzi kulula ukubukhupha.

2. I-antifreeze kukunciphisa indawo yokukhenkceza yesisipholisi.Ngenxa yeqondo eliphezulu lokukhenkceza kwamanzi, kulula ukukhenkceka xa isetyenziswa kwimozulu ebandayo kunye neqondo eliphantsi lobushushu.

3. Ezinye izongezo

Izongezo ngokubanzi azikho ngaphezulu kwe-5%, ikakhulu i-corrosion inhibitor, i-buffer, i-anti-scale agent, i-antifoaming agent kunye ne-colorant.

(1) I-Corrosion inhibitor: inokuthintela ngokufanelekileyo ukubola kwezinto zetsimbi kwinkqubo yokupholisa, kuba umbhobho wokupholisa ubukhulu becala wenziwe ngamalungu esinyithi, kwaye inkqubo yokupholisa ithanda ukubola kunye nomonakalo phantsi kwemeko yoxinzelelo oluphezulu, umthwalo wobushushu. kunye ne-corrosive medium.

(2) I-Scale inhibitor: inokususa ngokufanelekileyo isikali kunye nokuphucula amandla okutshatyalaliswa kobushushu.Ngexesha lokusetyenziswa kwesipholisi, isikali sihlala sisenziwa kumphezulu ongaphakathi wenkqubo yokupholisa.I-thermal conductivity yesikali iphantsi kuneyetsimbi, echaphazela kakhulu ukutshatyalaliswa kobushushu obuqhelekileyo.

(3) i-agent ye-antifoaming: inokuthintela ngokufanelekileyo i-foaming, i-coolant kwimpompo ngesantya esiphezulu phantsi kokujikeleza okunyanzeliswayo, ngokuqhelekileyo ivelisa i-foam, i-foam eninzi ayichaphazeli nje ukusebenza kakuhle kokudluliselwa kobushushu, kodwa iphinda ikhulise i-corrosion ye-cavitation yempompo.

(4) umbala: kwinkqubo yokusebenzisa into yokupholisa, kuyafuneka ngokubanzi ukuba kongezwe umbala othile, ukuze into yokupholisa ibe nombala omangalisayo.Ngale ndlela, xa inkqubo yokupholisa ingaphumeleli, indawo yokuvuza inokumiselwa ngokulula ngokujonga umbhobho wangaphandle wenkqubo yokupholisa.

Okwesithathu, ulwahlulo lwesipholisi

I-injini yokupholisa yohlulwe ibe yi-glycol coolant kunye ne-propylene glycol yokupholisa ngokwe-antifreeze:

I-1, i-ethylene glycol umthamo wobushushu obuthile, ukuhanjiswa kwe-thermal, i-viscosity kunye nenqanaba lokubilisa ziiparamitha ezibalulekileyo ezichaphazela ukuhanjiswa kobushushu kwesisombululo se-ethylene glycol samanzi.Umthamo othile wokushisa kunye ne-thermal conductivity ye-ethylene glycol isisombululo se-aqueous siyancipha ngokunyuka koxinzelelo, kwaye i-viscosity iyanda ngokunyuka koxinzelelo.

I-2, i-propylene glycol ekunciphiseni ukusebenza kwendawo yokukhenkceza kunye ne-glycol ngokusisiseko iyafana, kodwa kunye netyhefu encinci kune-glycol, ixabiso libiza kakhulu kune-glycol.

Isine, ukugcinwa kwenkqubo yokupholisa

1. Ukukhethwa kwesipholisi

(1) Ukuze kuthintelwe inkqubo yokupholisa ekukhenkceni, i-antifreeze efanelekileyo inokukhethwa.Ngokubanzi, indawo yokukhenkceza yesithinteli-mkhenkce kufuneka ibe ngaphantsi kwe-5℃ kunobona bushushu buphantsi kwindawo.

(2) Iindidi ezahlukeneyo ze-antifreeze azikwazi ukuxutywa.

2. Ixesha lokutshintshwa kunye nokusetyenziswa

(1) Umjikelo wokutshintshwa: Isipholisi kufuneka sitshintshwe kube kanye emva kweminyaka emi-2-3, ngokungqinelana nencwadana yokusebenza.

(2) Imali eyongeziweyo: I-Antifreeze kufuneka yongezwe kwitanki yokwandisa phakathi kwe-F (MAX) kunye ne-L (MIN) amanqaku kwimeko yokupholisa injini.

3. Ulondolozo lwemihla ngemihla:

(1) Kufuneka kuqwalaselwe yonke imihla, xa kukho ukupholisa okungonelanga, iimpawu ezimhlophe kumphezulu wombhobho wamanzi okanye ubisi olumhlophe kwi-oyile, kukuvuza kwesipholisi.

(2) Jonga indawo yoqhagamshelo kunye nemeko yazo zonke iibhobho zesixokelelwano sokupholisa kunye nemibhobho yesifudumezi.Ukuba kukho ukwandiswa okanye ukuwohloka, nceda uyibuyisele ngexesha.

Isishwankathelo: Inkqubo yokupholisa idlala indima ebaluleke kakhulu kwimoto.Ekusetyenzisweni kwemihla ngemihla, kufuneka igcinwe rhoqo, ukuze iphephe umoya kwaye igcine imoto ikwimo elungileyo.Kufuneka ijongwe rhoqo ukuba isixhobo sokupholisa injini sanele na, kwaye isisipholisi esifanelekileyo kufuneka songezwe okanye sitshintshwe ngexesha xa kufuneka.
