Momo o te ārai makariri. Te hanganga, ngā āhuatanga, whakaaro

Ārai makariri (i te reo Ingarihi "Freeze") - he wā ngā mo nga ringihanga motuhake mō te meangiti wera ka nga wae - engines ā parariraa, tāuta ahumahi, papua, me ētahi atu, ka mahi i raro kore ... He ngā momo o anti-Freeze, a hoki āhuatanga rerekē. He āhuatanga o enei wai ko te wāhi mīti iti me te ira e koropupu ana tiketike. I roto i te engines automotive me whakamahia taua noa wai. Kia mahara te reira e kore te mea mure ore te ārai makariri. E tika ana kia wa ki te huri, rawa i roto i nga wa atu-wa. Kia aroha mai, e rave rahi rangatira motokā wareware tenei tukanga, ringihia e mai pepa ranei. Na, ko reira he kaupapa rawa whanui, i te mea e tika ana ki te matau me te mohio ki nga āhuatanga ariā o te kōwhiringa o te coolant. I mua i feruri koe i roto i te mea he kia atu te tūhura i te whakarōpū o ārai makariri aha te mea te reira me aha ko te pūnaha meangiti.

Ko te pūnaha meangiti o te pūkaha ngingiha ā-

Ko mārama i te taitara rite, kia rite ki te hua o te tukanga e puta ana i roto i te pūkaha, e tona whakawera wahi. Na reira, me te reira tautauā. Kei te kawea te reira i roto i na roto i te komuhumuhu i te wai te meangiti. neke ia i roto i takere motuhake. Na, he aha te mea te ārai makariri, me pehea e mahi i te reira?

Ko te wai e haere ana i roto i te takere, he wera, me te ka tomo te makariri, te matao o nei te. I muri i korerotia i tenei huringa te. honotanga ārai makariri tonu i raro i te pēhanga, e whakarato ana te papu motuhake.

coolant whakaaro

Hei tango wera i te pūkaha, he wai motuhake. I tua atu ki te tautauā, reira equalizes hoki te pāmahana o ngā wahi o te pūkaha. Takere i roto i nei honotanga coolant, kia te mutunga riro tanumia ki waikura me putunga. I roto i taua wahi, ka rere i te pūkaha wera. Na reira, ka maha puta nga breakdowns pūnaha meangiti matenga rango warping.

He mahi tuarua o kohuatia ko te whakawera roto, me te kono kātere. Ko te kupu, ngā te whakamahana e i roto i te kōwae tautauā me ko te wāhi. I mua i te taeraa mai o te ārai makariri rongonui i roto i te pūnaha meangiti ki tonu te wai noa. Otiia i reira he torutoru kohakore. Tuatahi, paari te wai i 0 nekehanga, me te kupu E faarahi, e haehae ana poraka rino rango. Na reira, i roto i te Soviet Union i hiahiatia tino i roto i te wa makariri katoa ahiahi ki te tatau i te wai i te pūnaha meangiti. Tuarua, whewhe te wai i 100 nekehanga. Ahakoa kahore e nga motors te tahu ki te pāmahana i raro i ngā āhuatanga noa. Otiia kihai i nohinohi te i roto i te whenua pukepuke i tenei kohua. He toru ngoikoretanga o te wai - ki te whakatairanga waikura. Te meangiti awa me aerodynamics roto te pūkaha kaha waikuratia ta ka heke ratou kawe ia waiariki.

Ko te hanganga o te ārai makariri

Na, he aha te mea te ārai makariri? Simplistically, ngā reira o e rua ngā wāhanga:

• Fundamentals.
• tāpiritanga Matatini.

Pūtake - Ko te hanganga wai-glycol (e kore e mea faufaa te reira he aha enei momo o anti-Freeze). Tei te reira i runga i te kaha, me te kore e tio i flowability pāmahana iti, te kaha wera motuhake. Ko te wāhanga nui te nuinga o tetahi coolant he ethylene glycol. Heoi, tona ranunga ki te wai whakatairanga hoki i te waikura o te meangiti huānga pūnaha. Ko e founga ki te kia i roto i tenei āhuatanga? Hoki tenei wahi o nga turanga o tāpiritanga tāpiri. Ko te antifoam matatini, anticorrosive me te aueue wae. I tua atu, kei te te ārai makariri maha tāpiri hā hā me āpiha tae.

Types o ngā hua, me o ratou āhuatanga

E wehea coolants Modern ki e rua ngā momo - magnesium me carboxylate. Te tangata e matau pā āta ārai makariri ki te momo tuatahi rite te utu tino, a ao. Silicates e taketake tāpiri pararopi i roto i te coolant. Iti o enei matū ko e e takoto ratou i runga i nga taiepa o te poraka puoto i roto i nga awa, me te arai atu i te whakawhitinga wera noa. Ko te hua - he pūkaha pukā auau. He he tetahi drawback nui - kia ārai makariri pararopi kia puta ke i te iti rawa 30 mano kiromita. Kore ka waiho reira mārama tohu o te waikura o te meangiti takere, e ka kia uaua ki te hapai i. E tito ārai makariri Organic o te waikawa organic anake. Ko te taa o enei tāpiritanga ko e hipokina e ratou te wāhi anake ki te waikura whakakitea. Nā ki te kawe ia ngāwhā o te takere meangiti he kore e pōhara kē whakaritea. Ko tētahi atu painga o te ārai makariri organic - he mahi wā roa. Ka taea te whakamahi i te hua ki runga ki te 150,000 kiromita ranei ki runga ki te rima tau.

whakarōpū o ārai makariri

I te kau, ārai makariri e toru anake ngā momo: G11, G12 me G13 (mo te whakarōpū o General Motors USA) - i roto i runga i te ihirangi o tāpiritanga. Class G11 - tīmata, ki taketake tāpiritanga pararopi me ngā āhuatanga tiaki iti. He pai mō ngā waka pāhihi me ngā taraka enei wai.

Ārai makariri Ko maha tenei rōpū kauruku matomato puru ranei. Ko reira ki ngā whānui i roto i to tatou ārai makariri whenua tenei piha. Class G12 - te momo matua o te ārai makariri. Ko te hanganga ngā tāpiritanga organic (carboxylate me ethylene glycol). Taua ārai makariri hangaia matua mō ngā taraka taimaha me engines tiketike-tere hou. Ko reira pai mo te ohipa taimaha e rapua e tautauā mōrahi.

He tae whero māwhero ranei. Class G13 hanga ārai makariri, e te kaimahi rite te pūtake mō te propylene glycol. tae kōwhai karaka ranei kaihanga ārai makariri taua. Ko tōna āhuatanga āhuatanga ko e ko te reira i roto i te whakapā ki te taiao o waho te tere decomposed ki wāhanga, pērā ethylene glycol. Ko te kupu, ko te hua o te rōpū 13 e ake taiao.

Tīpakohia te momo o te ārai makariri

Ārai makariri, rite kua whakahuatia, ko reira he hua kounga i roto i te piha haapiiraa. Heoi e kore e nohopuku i runga i taua mea, atu - pai. I tua atu ki te akomanga, i reira ko tetahi whakarōpū o ārai makariri. He rite ki te whakamahi i wai me aro te reira. Ko te tuatahi e taea te tūtohutia ki kaitaraiwa tauhou, a taea rehe ite te whakamātau ki aro. Me diluted ratou ki te wai māturu ki te rahi e hiahiatia ana.

Ko te kōwhiringa o te waitohu o te ārai makariri

Nā ki te meka e te inu meangiti - he āhuatanga whakapau tika o tetahi pūkaha parariraa ā, ka tenei hua momo nui o ngā kaiwhakanao. I roto i te noa tino nehenehe tatou e whakahua i te torutoru kamupene. I roto i to tatou whenua ko reira: "Pirika", "Alaska", "Sintek". Enei hua Ko te ōwehenga tino tautika o "utu-te kounga". Ārai makariri "Pirika" tirohia ki te piha haapiiraa G12, e nui faarahi ratou faaohiparaa. Hua "Alaska" e pā ana te ki te ārai makariri (piha G11 ki tāpiritanga pararopi).

Tei runga i te whakatinanatanga, "Alaska" Ka taea e te mahi i roto i te whānuitanga pāmahana whānui: -65 ki te 50 nekehanga (Arctic me hanganga pārūrū). O te akoranga, haamau piha G11 etahi here i runga i te mauroa o te inu, me ona āhuatanga. Heoi, utu manapori he rawa he take nui. E hangaia Company "Sintek" hua te nuinga i roto i te piha haapiiraa G12. tino ārai makariri taua mo te hou katoa engines. Tāpiritanga i roto i tenei hua - arai, kamupene, ārai putunga me te waikura i runga i nga papa i roto o te pūnaha tautauā.

Mixing rama rerekē

Me mea he kupu ruarua e pā ana ki te ranu rama rerekē o te coolant. He ngā momo o te ārai makariri, me ratou hototahi, kāore, e whangai ana ki te kore. Ka rite ki te hua, kia ara ake taupatupatu i waenganui i te ngā tāpiritanga.

Ka taea e te hua e tino rerekē, ara tūkino te rapa putorino o te pūnaha meangiti me tanumia o takere i roto i te poraka pūkaha. kia whanau te reira i roto i te ngakau e i roto i te pūnaha hangaia ki te mahi ki te ārai makariri, kei te tino riria ana ki te ringihia te wai. Mai te mea he kaha wera nui, te huri i te āhuatanga waiariki o te pūnaha tautauā. Hoki, ngā momo rerekē o te coolant tika ki tona hanganga, me te aroaro o tāpiritanga i ngā āhuatanga lubricating, me te wai mā te whakamahi i, matua, ka tupuheke te papu wai. Kino, ki te i muri i te wai ano ki te whakaki i ārai makariri. pāhekoheko e ia ki te tote, taratahi nei te i te wai tīmata huka. Na ka takoha ia i roto i ngā āputa iti me turuturu. Ko te take ki tetahi coolant (e kore e mea faufaa te reira he aha te ahua o te ārai makariri whakauru) tenei.

Ārai makariri hei tohu o te āhua hangarau o te motokā

Herenga o te coolant i roto i te pūkaha autaki taea te mahi kia rite ki te tohu o te poipoi mihini, me te wahi ki te whakaatu e pā ana ki tona huru. Ki te he pouri me te kapua, me tohu o waipara i te raro o te tank ngaru, te waka ki te tēnei pukapuka nui e kore anake, engari ki te tohu o te tiaki rawakore te hua.

e kore e rangatira Te tiaki me te tahuri whakaroa te whakakapinga o te coolant ki te whakamutunga.

Āhuatanga o te mahi o waka ki ārai makariri i roto i te pūnaha meangiti

Kia kore ai te ārai kino titau pūnaha tautauā auau. I roto i te mahi, ārai makariri, e mahi ana i tona mahi matua, ko te whakawhitinga o te wera i te pūkaha ki te whakamahana, ino roa ki te wā. No mea he aha te ahua o te whakamahi. A te huri hoki ngā āhuatanga ārai makariri ki te wā. I tua atu ki te āhua o te wai ano aroturuki, e kore e ngaro titiro o te pūnaha iho. Me tino hiri reira. e kore e e ngote te reira i whakapau rangi ranei. Ko te ahua o te pūnaha meangiti taua e faatupu te whakaiti i roto i ngā āhuatanga whakawhiti wera. Ko te mīhini Ko te hua o te tere overheat, ārahi te matenga puoto. Motor tata tua atu te hanga.

Na, ka kitea e matou momo o ārai makariri, me ratou hototahi ki ia atu.
