Ọrụ nke sistemu jụrụ oyi nke ụgbọ ala bụ ịgbasa ọkụ nke injin ahụ n'oge, nke mere na injin ahụ na-arụ ọrụ na okpomọkụ kachasị mma.The ezigbo ụgbọala jụrụ usoro kwesịrị ọ bụghị nanị izute mkpa nke engine jụrụ, ma na-ebelata okpomọkụ ọnwụ na ike oriri, nke mere na engine nwere mma ike ịzọpụta mmetụta na ndabere nke n'ịhụ ezi ike ịrụ ọrụ.

I. Ụkpụrụ na-arụ ọrụ nke usoro jụrụ oyi

Sistemụ jụrụ oyi na-arụ ọrụ dị oke mkpa n'ime ụgbọ ala ahụ, sistemu jụrụ oyi na-anabatakarị mmiri jụrụ oyi, sistemu oyi a na-ahụkarị bụ nke radiator, sooks radiator, thermostat, mgbapụta mmiri, fan jụrụ oyi na eriri fan.

Ọ na-adabere na mgbapụta mmiri jụrụ oyi nke na-esi na ngwa nju oyi mmanụ, crankcase jụrụ oyi na n'ime isi cylinder, na-ewepụ oke ọkụ engine.

Nnukwu mgbasa: mgbe engine na-arụ ọrụ n'okpuru nkịtị thermal ọnọdụ, ya bụ, mmiri okpomọkụ dị elu karịa 80 ℃, jụrụ mmiri niile kwesịrị isi na radiator na-etolite a isi mgbasa.Isi valvụ nke thermostat na-emeghe nke ọma ma mechie valve nke abụọ.

Obere mgbasa: mgbe mmiri jụrụ oyi dị n'okpuru 70 ℃, nrụgide uzuoku na igbe mgbasawanye dị ntakịrị, na mmiri jụrụ oyi adịghị eruba site na radiator, kama ọ bụ naanị na-ebufe obere mgbasa n'etiti jaket mmiri na mgbapụta.

Abụọ, ọrụ nke coolant

Igwe oyi na-arụ ọrụ dị oke mkpa na arụ ọrụ nkịtị nke injin ahụ.Oke okpomọkụ ma ọ bụ dị ala nke coolant ga-emetụta ọrụ nke injin ahụ n'ụzọ dị njọ.Ọ bụrụ na okpomọkụ nke engine coolant dị oke elu na viscosity nke mmanụ lubricating na-ebelata, mfu esemokwu nke akụrụngwa engine ga-esiwanye ike.

Ọ bụrụ na engine coolant okpomọkụ dị oke ala, viscosity nke lubricating mmanụ na-abawanye na fluidity na-aghọ ogbenye, nke na-adịghịkwa mma ka lubrication, si otú ibelata ike mmepụta nke engine na-emetụta n'ibu arụmọrụ nke engine.

Coolant bụ ihe na-enye ọkụ na-ekpo ọkụ na usoro dị jụụ, na-eme ka ọ dị jụụ, mgbochi corrosion, mgbochi ọnụ na mgbochi na ọrụ ndị ọzọ, ọ na-agụnye mmiri, mgbochi freeze na ihe mgbakwunye dị iche iche.

1. Mmiri bụ akụkụ dị mkpa nke coolant.Ọ nwere nnukwu ikike okpomọkụ kpọmkwem na njikwa ọkụ ngwa ngwa, na okpomọkụ nke mmiri na-etinye n'ime ya dị mfe iji.

2. Antifirizi bụ iji belata kefriza ebe coolant.N'ihi oke mmiri na-akpụ akpụ, ọ na-adị mfe ifriizi mgbe ejiri ya na oyi na ihu igwe dị ala.

3. Ihe mgbakwunye ndị ọzọ

Ihe mgbakwunye n'ozuzu adịghị ihe karịrị 5%, tumadi corrosion inhibitor, ihe nchekwa, ihe mgbochi ọnụ ọgụgụ, ihe na-egbochi ụfụfụ na agba.

(1) Corrosion inhibitor: ọ nwere ike n'ụzọ dị irè igbochi corrosion nke metal bekee na jụrụ usoro, n'ihi na jụrụ pipeline bụ tumadi mejupụtara metal akụkụ, na jụrụ usoro bụ mfe corrosion na mmebi n'okpuru ọnọdụ nke elu mgbali, okpomọkụ ibu ibu. na ihe na-emebi emebi.

(2) Onye na-emechi ọnụ ọgụgụ: ọ nwere ike wepụ ọnụ ọgụgụ nke ọma ma melite ikike ikpo ọkụ ọkụ.N'oge a na-eji coolant, a na-etolitekarị ọnụ ọgụgụ n'elu ime nke usoro jụrụ oyi.The thermal conductivity nke ọnụ ọgụgụ dị ala karịa nke metal, nke ukwuu na-emetụta nkịtị okpomọkụ dissipation.

(3) antifoaming gị n'ụlọnga: nwere ike n'ụzọ dị irè gbochie ụfụfụ, coolant na mgbapụta na elu na-agba n'okpuru mmanye mgbasa, na-emekarị na-emepụta ụfụfụ, a otutu ụfụfụ ọ bụghị nanị na-emetụta okpomọkụ nyefe arụmọrụ, ma na-eme ka cavitation corrosion nke mgbapụta.

(4) colorant: n'usoro iji coolant, a na-achọkarị ịgbakwunye otu agba, nke mere na coolant nwere agba dị egwu.N'ụzọ dị otú a, mgbe usoro jụrụ oyi na-ada, ebe nkwụsịtụ nwere ike ikpebi ngwa ngwa site n'ikiri pipeline dị n'èzí nke usoro jụrụ oyi.

Atọ, nhazi ọkwa nke coolant

A na-ekewa igwe oyi akwa n'ime glycol coolant na propylene glycol coolant dị ka antifirizi si dị:

1, ethylene glycol kpọmkwem okpomọkụ ikike, thermal conductivity, viscosity na esi ebe bụ ihe dị mkpa paramita na-emetụta okpomọkụ nyefe arụmọrụ nke ethylene glycol aqueous ngwọta.The kpọmkwem okpomọkụ ike na thermal conductivity nke ethylene glycol aqueous ngwọta na-ebelata na mmụba nke ịta, na viscosity na-abawanye na-abawanye nke ịta.

2, propylene glycol na mbenata kefriza ebe arụmọrụ na glycol bụ ihu ọma otu, ma na-erughị egbu egbu karịa glycol, price bụ dị oké ọnụ karịa glycol.

Anọ, nhazi usoro jụrụ oyi

1. Nhọrọ nke coolant

(1) Iji gbochie sistemu jụrụ oyi, enwere ike ịhọrọ ọgwụ mgbochi kwesịrị ekwesị.N'ozuzu, ebe oyi na-ekpo ọkụ nke antifirizi kwesịrị ịdị 5 ℃ dị ala karịa okpomọkụ kacha ala na mpaghara ahụ.

(2) Enweghị ike ịgwakọta ụdị antifirizi dị iche iche.

2. Oge ngbanwe na ojiji

(1) Ntughari okirikiri: Ekwesịrị dochie Coolant otu ugboro kwa afọ 2-3, dịka ntuziaka ọrụ si dị.

(2) Ọnụ ego mgbakwunye: A ga-agbakwunye antifirizi na tank mgbasawanye n'etiti akara F (MAX) na L (MIN) na ọnọdụ jụrụ oyi nke injin ahụ.

3. Nlekọta kwa ụbọchị:

(1) Ekwesịrị itinye nlebara anya kwa ụbọchị na nlele, ozugbo enwere obere coolant, akara ọcha n'elu ọkpọkọ mmiri ma ọ bụ mmiri ara ehi na-acha ọcha na mmanụ, ọ bụ ntapu nke coolant.

(2) Lelee ọnọdụ njikọ na ọnọdụ nke ihe niile dị jụụ usoro hoses na kpo oku hoses.Ọ bụrụ na enwere mmụba ma ọ bụ mmebi, biko dochie ya n'oge.

Nchịkọta: Usoro oyi na-arụ ọrụ dị oke mkpa n'ime ụgbọ ala.N'iji ya eme ihe kwa ụbọchị, a ga-edobe ya ugboro ugboro, ka ikuku wee mee ka ụgbọ ala ahụ dị mma.Ekwesịrị ka a na-enyocha ya mgbe niile ma igwe jụrụ oyi zuru oke, ma ekwesịrị ịgbakwunye ma ọ bụ dochie coolant kwesịrị ekwesị n'oge mgbe achọrọ ya.
