Ārai makariri kiato i runga i te pāmahana rānei. Ka taea e ahau uru ārai makariri i roto i ngā tae rerekē?

A, no te whakahaere i te maha o ngā pūnaha ora-tautoko, engines, puta āhuatanga mea i roto i te wa makariri, ka pā tōraro te pāmahana kino ambient nga āhuatanga ōkiko o te fluids e te hunga i roto ia ratou. Hei tauira, tenei wai meangiti te taviniraa ki te ārai pukā o te tikanga a ratou ano ranei ngā coolants.

Na reira, te tono i te inu anti-Freeze pera-ka karanga. Ārai makariri - he taonga wai, te mau tonu tana āhuatanga katoa ahakoa o huringa pāmahana. Ārai makariri whakamahia i roto i te hanga, te hanga o ngā waka, whakawera me ngā pūnaha ventilation o whare tūmataiti ranei whare ahumahi.

Coolants me o ratou momo

Ko te hanganga o tata katoa anti-Freeze: te wai me tāpiritanga motuhake. Ko te pūtake o tetahi coolant taea e:

Ko te painga matua o tenei momo o te ārai makariri ko tona haumaru. Ko te aha te kaha reira whakamahia i roto i te pūnaha whakawera rua-iahiko, mai ara ki te riro te taonga ki te ara iahiko, me te wai wera, kahore e wehingia ana, ka tupu. I tua atu, whakamahia propylene glycol te rite te kaihoko i roto i te ahumahi rare, he hoki he tāpiri kai. Tikanga, propylene glycol he matomato. No te mea o te wātea arumoni o tae rerekē, me te ārai makariri whakama whakatika rite ki ranei he reira taea ki te uru rerekē tae ārai makariri e kore ranei. Te reira i katoa tei runga i te whakaaro me tikanga o te whakamahi. Ka rite ki te tahi atu antifreezes, propylene glycol mīti pāmahana ko e pā ana ki -35 C.
• glycol ethylene - ārai makariri rawa rongonui, te nuinga no te mea o tona uara mākete iti, a hoki, he mea e wātea ana i roto i ngā puka e rua: me to'eto'e -30 ° C, me te -65 ° C. Ko te rerekētanga matua - nui haere te ati ki te hauora tangata. Na reira ko te whero tenei tohu o ārai makariri, na e i roto i te take o te leakage ko reira te kite, me te taea hohoro faaore ona mau hopearaa.
• Triethylene glycol - Kei te uaua whakamahia atu ārai makariri, te nuinga i roto i te hunga tono i reira pāmahana teitei. whakaaro TEG te he ārai makariri motuhake.

Na reira, maitiraa e waitohu o ārai makariri hiahiatia ki a koutou, he pai ki te whakaoti i te take noa i mua i te hanga o te whare.

āhuatanga ārai makariri me ratou āhuatanga

āhuatanga ārai makariri e te hunga nui i roto i to ratou mahi

Ko ratou e whai ake:

• Mahi mo te wa roa. Te kore whakakapi i te pūnaha coolant ārai makariri e taea te mahi humarie i roto i te wā roa. Tenei tutuki ora noa me te roa o te pūnaha whakawera ventilation ranei katoa.
• Ārai makariri ātete ki te mahi te waikura. Ko reira e tika ana ki te aroaro i roto i te hanganga o te tāpiri motuhake ārai makariri e kore e hanga i waikura i roto i ngā pūnaha whakawera. faarahi tenei te tōtika o te whakawera wāhi, me i te wa taua tino whakaiti utu pūngao.
• Ātete ki cavitation. I roto i te wai tikanga ki te heke te pēhanga pūnaha e, takanga o mirumiru heipü puta. I roto i te take o te ārai makariri e kore e kitea. Ko te kupu, pa'anga hoki ratou pūnaha i puranga waipēhi me wiri.

I roto i te hanga o tāpiritanga ārai makariri whakamahia tika. e kia poauau Non-whakamahi o enei wae i roto i te glycol propylene me ethylene glycol i te wāhi ōhanga o te tirohanga.

Onäianei ka hoko ārai makariri

Mea katoa e hokona i roto i te mākete hanga ārai makariri i utu rerekē i runga i te waitohu, te kaihanga, āhuatanga mahi motuhake o te taonga iho rānei. maha hoko iwi kuware pereoo ārai makariri, ki ona pūnaha whakawera (hinu hiko, ārai makariri, me ētahi atu).

Waimeha te ārai makariri, ko te wai pai maturuturu. e kore e roto i te reira i tai matū pērā i te konupūmā me te konupora, na uara te tikanga ngawari e hiahiatia ana. Ko te wai mua, ka whakamahia i roto i te taha ki te anti-Freeze he pea ki te hua ano hoki i roto i te hanganga o te rerenga. pakeke manakohia whakamahia ki te waimeha te wai ārai makariri ko 5 mg-ekvp.

A, no te mau ana i roto i tetahi mahi i runga i te pūnaha whakawera hiahiatia te ki aroturuki tohu pērā i ārai makariri kiato. TÜTOHI te tikanga whakanohoia ki runga ki te taha ki muri o te ipu, e taea te āwhina te reira ki te whakatau i te tawhā o tenei coolant waitohu.

Ethylene glycol ārai makariri iti kawe ia waiariki i te wai (15-20%).

Kahore te wehi o te whakaiti i te whai huatanga o te pūnaha whakawera anti-Freeze taea te whakamahi mō te 5 tau. Aru e tino tatau te koroheke, me riringi ma, coolant hou.

I roto i te mea whanganga i te kiato o te ārai makariri?

tohua te kiato te i roto i te karamu ia cm pūtoru. Tirohia te wāhi mīti me te nui o te ethylene glycol ārai makariri kiato awhina. Kei tepu kiato he maha o tohu, e mea ohie ki te whakamahi.

Hei tirohia te kiato o te ārai makariri, ka taea e koe te whakamahi i te ine kiato wai. Ko tenei he pūrere mō te ine i te kiato o te ārai makariri. E rua unahi - ki te ine i te kiato, me te mīti wāhi.

Ki te kore e te otinga whātioata, taea te whakamahi i tēnei ārai makariri i te pāmahana o te -24 ° C (toharite kōpaka pāmahana).

taui tino mātotoru o coolant rite ki te pāmahana, me ka whakamahia i mahana i raro -65 ° C reira whakawhanake tonu, me te hanehane. Ka rite ki te hua, whakapōrearea te pūnaha whakawera, ka haere te coolant raro.
