Umsebenzi wesistimu yokupholisa imoto ukuqeda ukushisa kwenjini ngesikhathi, ukuze injini isebenze ezingeni lokushisa elifanele kakhulu.Isistimu yokupholisa imoto efanelekile akufanele nje ihlangabezane nezidingo zokupholisa injini, kodwa futhi inciphise ukulahlekelwa ukushisa nokusebenzisa amandla, ukuze injini ibe nomthelela ongcono wokonga amandla ngesisekelo sokuqinisekisa ukusebenza kahle kwamandla.

I. Umgomo wokusebenza wesistimu yokupholisa

Isistimu yokupholisa idlala indima ebaluleke kakhulu emotweni, isistimu yokupholisa injini ngokuvamile isebenzisa ukupholisa kwamanzi okupholisa, isistimu yokupholisa evamile yakhiwa irediyetha, ipayipi le-radiator, i-thermostat, iphampu yamanzi, ifeni yokupholisa kanye nebhande lefeni.

Ithembele empompini yamanzi okupholisa ageleza endaweni yokupholisa uwoyela, ijakhethi yamanzi okupholisa i-crankcase nasekhanda lesilinda, isuse ukushisa kwenjini okweqile.

Ukujikeleza okukhulu: lapho injini isebenza ngaphansi kwezimo ezivamile zokushisa, okungukuthi, izinga lokushisa lamanzi lingaphezu kuka-80℃, amanzi okupholisa kufanele wonke ageleze kurediyetha ukuze akhe ukujikeleza okukhulu.I-valve eyinhloko ye-thermostat ivuleke ngokugcwele futhi i-valve yesibili ivalwe ngokugcwele.

Ukujikeleza okuncane: lapho izinga lokushisa lamanzi okupholisa lingaphansi kuka-70 ℃, ukucindezela kwesitimu ebhokisini lokunweba kuncane kakhulu, futhi amanzi okupholisa awahambi nge-radiator, kodwa ahambisa kuphela ukujikeleza okuncane phakathi kwebhantshi lamanzi nepompo.

Okwesibili, indima yokupholisa

Isipholile sidlala indima ebaluleke kakhulu ekusebenzeni okujwayelekile kwenjini.Izinga lokushisa eliphezulu kakhulu noma eliphansi kakhulu lesipholisi kuzoba nomthelela omubi ekusebenzeni kwenjini.Uma izinga lokushisa lokupholisa injini liphezulu kakhulu futhi i-viscosity kawoyela wokugcoba inciphile, ukulahleka kokungqubuzana kwezingxenye zenjini kuzoqiniswa.

Uma izinga lokushisa elipholile lenjini liphansi kakhulu, i-viscosity kawoyela wokugcoba iyanda futhi uketshezi luba lubi, nakho okungakwazi ukugcobisa, ngaleyo ndlela kunciphisa amandla enjini futhi kuthinte ukusebenza kahle kwemishini.

I-Coolant iyindawo yokudlulisa ukushisa ohlelweni lokupholisa, enokupholisa, i-anti-corrosion, i-anti-scale kanye ne-anti-freezing kanye neminye imisebenzi, yakhiwe ngamanzi, i-antifreeze kanye nezithasiselo ezihlukahlukene.

1. Amanzi ayingxenye ebalulekile yesipholile.Inomthamo omkhulu wokushisa othize kanye ne-conductivity yokushisa esheshayo, futhi ukushisa okumuncwa amanzi kulula ukukukhipha.

2. I-antifreeze ukunciphisa indawo yokuqandisa yesibandisi.Ngenxa yezinga eliphezulu lokuqandisa lamanzi, kulula ukuqanda uma lisetshenziswa esimweni sezulu esibandayo nesiphansi.

3. Ezinye izithasiselo

Izithasiselo ngokuvamile azidluli ku-5%, ikakhulukazi i-corrosion inhibitor, i-buffer, i-anti -scale ejenti, i-antifoaming ejenti kanye nombala.

(1) I-Corrosion inhibitor: ingavimbela ngempumelelo ukugqwala kwezinto zensimbi ohlelweni lokupholisa, ngoba ipayipi lokupholisa lakhiwa ikakhulukazi izingxenye zensimbi, futhi isistimu yokupholisa ijwayele ukugqwala nokulimala ngaphansi kwesimo somfutho ophezulu, umthwalo wokushisa. ne-corrosive medium.

(2) I-Scale inhibitor: ingasusa ngempumelelo isikali futhi ithuthukise amandla okukhipha ukushisa.Ngesikhathi sokusebenzisa isipholile, isikali sivame ukwakheka endaweni engaphakathi yesistimu yokupholisa.I-thermal conductivity of scale iphansi kuneyensimbi, ethinta kakhulu ukuchithwa kokushisa okuvamile.

(3) i-ejenti ye-antifoaming: ingavimbela ngokuphumelelayo ukugwedla, ukupholisa ipompo ngesivinini esikhulu ngaphansi kokujikeleza okuphoqelekile, ngokuvamile ukukhiqiza igwebu, igwebu eliningi alithinti nje ukusebenza kahle kokudlulisa ukushisa, kodwa futhi kubhebhethekise ukugqwala kwe-cavitation yepompo.

(4) umbala: ngesikhathi sokusebenzisa isipholile, ngokuvamile kuyadingeka ukwengeza umbala othile, ukuze into epholile ibe nombala ogqamile.Ngale ndlela, lapho uhlelo lokupholisa luhluleka, indawo yokuvuza inganqunywa kalula ngokubheka ipayipi langaphandle lesistimu yokupholisa.

Okwesithathu, ukuhlukaniswa kwe-coolant

Ukupholisa injini kuhlukaniswe i-glycol coolant kanye ne-propylene glycol coolant ngokusho kwe-antifreeze:

I-1, umthamo wokushisa othize we-ethylene glycol, i-thermal conductivity, i-viscosity kanye nephuzu elibilayo yimingcele ebalulekile ethinta ukusebenza kokudlulisa ukushisa kwesisombululo samanzi se-ethylene glycol.Umthamo wokushisa othize kanye ne-thermal conductivity ye-ethylene glycol aqueous solution kuncipha ngokwanda kokugxila, futhi i-viscosity iyanda ngokwanda kokugxila.

2, i-propylene glycol ekunciphiseni ukusebenza kwephuzu lokuqandisa kanye ne-glycol ngokuyisisekelo iyafana, kodwa futhi inobuthi obuncane kune-glycol, intengo ibiza kakhulu kune-glycol.

Okwesine, ukugcinwa kwesistimu yokupholisa

1. Ukukhethwa kwesibandisi

(1) Ukuze uvimbele uhlelo lokupholisa ekubazeni, kungakhethwa isinqanda-qhwa esifanele.Ngokuvamile, indawo yokubanda ye-antifreeze kufanele ibe ngaphansi ngo-5℃ kunezinga lokushisa eliphansi kakhulu endaweni.

(2) Izinhlobo ezahlukene ze-antifreeze azikwazi ukuxutshwa.

2. Isikhathi sokushintshwa nokusetshenziswa

(1) Umjikelezo wokushintsha: Isipholisa kufanele sishintshwe kanye njalo eminyakeni emi-2-3, ngokusho kwebhukwana lokusebenza.

(2) Inani elingeziwe: I-antifreeze kufanele yengezwe ethangini lokunweba phakathi kwamamaki F (MAX) kanye no-L (MIN) esimweni sokupholisa senjini.

3. Ukunakekelwa kwansuku zonke:

(1) Kufanele kuqashelwe nsuku zonke, uma kukhona ukupholisa okunganele, izimpawu ezimhlophe ebusweni bepayipi lamanzi noma ubisi olumhlophe emafutheni, kuwukuvuza kwesipholile.

(2) Hlola indawo yokuxhuma nesimo sawo wonke amapayipi esistimu yokupholisa namapayipi heater.Uma kukhona ukunwetshwa noma ukuwohloka, sicela uyishintshe ngesikhathi.

Isifinyezo: Uhlelo lokupholisa ludlala indima ebaluleke kakhulu emotweni.Ekusetshenzisweni kwansuku zonke, kufanele igcinwe njalo, ukuze ishaye umoya futhi igcine imoto isesimweni esihle.Kufanele ihlolwe njalo ukuthi isipholile senjini sanele yini, futhi isipholile esifanele kufanele sengezwe noma sishintshwe ngesikhathi lapho sidingeka.
