Hinu tuku: whakarōpū me ngā āhuatanga

hinu taputapu - hinu pūkaha piha motuhake hangaia mō te whakamahi i roto i kōpuku rerekē o waka te waku tuku, me te rite i roto i te momo o te taputapu. whakaputaina Motor me taputapu hinu i runga i te kohuke turanga waihanga ranei, a ka doped ki te momo o tāpiritanga, engari he teitei te whakaritenga tuku, no te mea mahi ratou i pikaunga nui teitei me hohoro te pepa o ngā mata waku. Ko tētahi o nga tohu tino nui o taua hinu ko te kaha ki te hanga i tētahi kiriata tiaki i runga i te mata o te wae te waku ki te ārai i whakapā aunoa i waenganui ia ratou. Ko te taputapu hypoid e whakamahia hinu, e, tomo ana ki te tauhohe matū ki te papa o nga wahi, te ārai ratou riro skipanie āhuatanga pēhanga tino. I roto i te mahi, oxidize hinu taputapu, me te riro poke, me te hiahia ki te kia whakakapia ia wā. whakaaro tenei kei te ki kia pai ka te hinu ki te hehema iti ki te hāora. Mai rerekē kamupene whakamahi tāpiritanga rerekē ki te uru ratou hua e kore e taea e. A, no te whakakapi i te kōwae tuku kia ata horoi, ki te taea te taua ki te hinu hou.

Whakaröpütia hinu taputapu rānei pokey i Mahinga ranei. Ko te kupu, kia rite ki te SAE (Association o Automotive Engineers) e wehea ratou ki e iwa akomanga - rima raumati me te wha hotoke (ki taupū W). Hoki te piha i tohua ia taupū pokey. SAE SAE 70W ranei 250, hei tauira. tohua taupū rua mō hinu multigrade (SAE 80W-90, etc.).

API (American hinu Institute) tuwhatuwhaia te hinu ki te 6 ngā akomanga, i runga i te āhuatanga whakahaere rānei - GL-1 ... GL-6. He rite ki te hunga e whakamahia ana i roto i te Soviet GOST 17479.2-85 TM1 ... TM6 enei akomanga. Kei te whakamahia te rōpū tuarima me te tuaono mō nihowhiti hypoid me whai te lubricity teitei me mahi pēhanga tino.

A, no te kōwhiri hinu taputapu, kia arotahi matua i runga i o ratou tikanga mahi. Ki te he i raro i tika te piha haapiiraa, noa kore he huarahi, me te teitei te kōeke hinu he utu teitei, e ka arahi ki overruns utu. He mea nui hoki ki te whakaaro i te pāmahana i ai te tuku e mahi, a ki runga ki tenei kaupapa ki te tīpako i te hinu. SAE 85W, hei tauira, ka mahi i pāmahana ki -12 ° C, ka kua 85W ki -40 ° C. I roto i te tuku aunoa , he wai iti-pokey motuhake, na kahore hinu pūkaha tuku ranei i reira e kore e tono.

I teie mahana, i runga i te mākete i te whānuitanga nui o ngā kaiwhakanao whakahere ratou hinu taputapu - Lukoil, Tapeke, Texaco, Reksol, Norse me te tini ke atu. He momo o tāpiritanga whakamahia whakatau te taumata o te kounga o hinu, me ratou whānuitanga utu. Ko te nuinga o ngawari te Mineral, engari he iti iho ō rite rite te ritenga. Na e te ngāwari pai kia āhua-ō rite te reo hari i waenganui i te rua tuatahi. kia hoki kia te reira tūpato o fakes me kore hoko hinu i roto i nga toa ngawari. Hurihia he utu neke atu i ki te tango i te hinu kounga pai, rawa inaianei e ki te whakakapinga o runga whakakapi ngotea ratou e 60 mano kiromita atu ranei nga wa katoa te pouaka.
