Mafuta a Gear 75w90 mawonekedwe

Khola la galimoto limatheka pokhapokha ngati mafuta apamwamba amagwiritsidwa ntchito pazinthu zamagalimoto. Mafuta azida amayenera kusamalidwa kwambiri ndi oyendetsa galimoto, koma tsopano mafuta amagetsi amagwiritsidwa ntchito kwambiri.

Cholinga chachikulu cha mafuta opatsira

Mafuta opatsira amafewetsera magiya a magalimoto m'magawo oyendetsera - magiya oyendetsa, ma axles oyendetsa, milandu yotumizira, ma gearbox ndi magetsi. Mafuta oterewa amachepetsa kutayika kwa mikangano ndikuchepetsa magawo azigawo zofalitsa, kuziziritsa komanso kuteteza magawo a mikangano ku dzimbiri.

Mafuta a gear amapangidwira:

• kuchepetsa kugwiritsira ntchito mphamvu pakukangana,
• kuteteza ziwalo kuti zisawonongeke,
• kuchepetsa kugwedera, mantha ndi phokoso,
• kuchotsa zinthu zovala kuchokera kumadera opikisana.

Mafuta a magiya amayenera kukhala ndi mawonekedwe abwino-kutentha. Amadzaza ma hydraulic system, kuthira mafuta makina opangira makina ndi ma hayidiroliki ndi zida zamagiya ndi nyongolotsi.

Kukhuthala kwa mafuta kumasankhidwa kutengera momwe zinthu zilili:

• pazipita - kuteteza zoperewera podula zidindo,
• Kuchepa - poyambira magawo opatsirana kutentha pang'ono ndikuchepetsa kutayika kwa mikangano.

Mukamagwiritsa ntchito mafuta apamwamba kwambiri okhala ndi mawonekedwe abwino, ndalama zambiri zimapulumutsa mafuta ndi mafuta.

Mitundu ndi kusiyana kwa kulolerana GL4 ndi GL5

Mafuta azida amagawika m'magulu asanu akuluakulu. GL5, GL4 ndi a kalasi yatsopano, yomwe idawonekera chifukwa cha bokosi lamagalimoto lomwe limafalitsa ma hypoid ophatikizidwa mnyumba imodzi. Kupanga kumeneku kunkafunika kuti mafuta awiri osagwirizana asakanikirane. Kwa iye, gulu la mafuta linapangidwa lomwe limakwaniritsa zofunikira zamakalasi osiyanasiyana.

Mafuta atsopano apadziko lonse lapansi amagwiritsidwa ntchito munthawi yomweyo poyendetsa magiya ndi ma gearbox:

• Ndi mafuta a GL5, kufalitsa kwa hypoid kumakhala kodalirika makamaka pakakhala zovuta zambiri komanso mantha.
• Mafuta a GL4 amapangidwira makamaka kugwiritsidwa ntchito m'mabokosi oyendetsera magalimoto oyenda kutsogolo. Mtundu uwu uli ndi theka la zowonjezera zowonjezera sulfure-phosphorous zomwe zimapanga zokutira podzikongoletsa m'malo opaka.

Chizindikiro cha GL4 / 5 chimagwiritsidwa ntchito ndi opanga aku Asia, ndipo dzina la GL4 + limagwiritsidwa ntchito pazinthu zopangidwa ku Europe. Oyendetsa magalimoto ena amawona kuti mafutawa ndi amitundu yosiyanasiyana, koma ndi olakwika.

Mafuta a gear 75w90: synthetics ndi semi-synthetics

Kusintha koyambirira kwa mankhwala opangidwa ndi theka kumakhala ndi 78-45% mchere, 20-40% opanga ndi 2-15% zowonjezera. Mafuta opangira zida amakhala ndi maziko okha.

Mafuta opanga 75W90 amapangidwa kuchokera ku polyalphaolefins okhala ndi zowonjezera zowonjezera kapena kuchokera ku hydrocracking agent okhala ndi zowonjezera. Makhalidwe akulu a mafuta a 75W90 ndi awa:

• Kuteteza mayunitsi opatsirana ku mikangano, makutidwe ndi okosijeni ndi kuvala,
• kukulitsa magwiridwe antchito,
• kuthekera kogwira ntchito m'malo otentha kwambiri,
• kusungunuka kwa mchere,
• kuteteza zisindikizo polima.

Mafuta a 75W90 ndiopanga, ngakhale kuti ambiri ogulitsa amawatcha kuti osapanga.

Chidule komanso mawonekedwe amafuta odziwika bwino

Taganizirani za mafuta otchuka kwambiri ochokera kwa opanga osiyanasiyana.

Mafuta opatsirana 75w90 Lukoil

Mndandanda wa mafuta a TM-5 ochokera ku Lukoil omwe ali ndi mawonekedwe otentha a mamasukidwe akapangidwe kazida zamagetsi zamtundu uliwonse zamagetsi. Mafutawa amagwiritsidwa ntchito kwambiri pamagalimoto osunthira magalimoto, ma axel oyendetsa, magiya oyendetsa, ndi zina zambiri. Lubrication imalola mayunitsi opatsirana opatsirana kutentha kwambiri ndipo amasunga mafuta kwambiri.

Castrol

Mafuta a Castrol 75W-90 amateteza kuti asavalike kwambiri. Akulimbikitsidwa kuti mugwiritsidwe ntchito pamagetsi opangira mafuta monga VW 501 50 ndi API GL4.

Bungwe lina

Semi-synthetic transmission mafuta TNK ndi ya gulu lapamwamba kwambiri ndipo imagwiritsidwa ntchito chaka chonse. Amapangidwa pogwiritsa ntchito matekinoloje amakono kuchokera pamafuta apamwamba kwambiri ndikuwonjezera zinthu zomwe zimatumizidwa kunja.

Nkhono

Mafuta a chipolopolo ali ndi magwiridwe antchito kwambiri ndipo adapangidwa kuti azigwiritsidwa ntchito pama transmissions olemera kwambiri a magalimoto amasewera.
