Mafuta a mafakitale I-40A

zizindikiro za thupi ndi mankhwala

Makhalidwe oyambira amafuta a I-40A:

1. Kachulukidwe kutentha firiji, kg/m³ 810 ± 10.
2. Kinematic mamasukidwe akayendedwe, mm²/ s, pa kutentha kwa 50 ^°C - 35 ... 45.
3. Kinematic mamasukidwe akayendedwe, mm²/ s, pa kutentha kwa 100 ° C, osati pansi - 8,5.
4. pophulikira, ^°C, osachepera -200.
5. Kuchuluka kwa kutentha, ^°C, osachepera -15.
6. Nambala ya asidi, malinga ndi KOH - 0,05.
7. Nambala ya Coke - 0,15.
8. Kuchuluka kwa phulusa,% - 0,005.

Mafuta atsopano a mafakitale I-40A (amatchedwanso mafuta IS-45 ndi mafuta a makina C) ayenera kuperekedwa kwa ogula pokhapokha atayeretsa distillate komanso popanda zowonjezera.

GOST 20799-88 imaperekanso kuti ikagwiritsidwa ntchito ngati hydraulic fluid, mtundu uwu wamafuta uyenera kuyesedwa kukhazikika kwake pazovuta zosiyanasiyana. Kukhazikika kwamakina kumatsimikiziridwa molingana ndi zisonyezo za mphamvu yakumeta ubweya wa wosanjikiza wopaka mafuta, womwe uli mumpata waukadaulo pakati pa malo oyandikira akusisita.

Chizindikiro chachiwiri cha kukhazikika kwa makina ndi nthawi yobwezeretsa kukhuthala kwa mafuta, yomwe imayikidwa molingana ndi njira ya GOST 19295-94. Pakufunsidwa kowonjezera, mafuta a I-40A amayesedwanso kukhazikika kwa colloidal. Mayesowa amakhala ndi kudziwa kuchuluka kwa mafuta omwe adapanikizidwa kuchokera mumafuta oyambira pogwiritsa ntchito penetrometer yolinganiza. chizindikiro ichi n'kofunika kuti zinthu ntchito mafuta pa kwambiri kusintha kutentha kunja.

Analogue yapadziko lonse lapansi yamafuta awa ndi Mobil DTE Oil 26, opangidwa molingana ndi ISO 6743-81, komanso mafuta opangidwa ndi makampani ena omwe amakwaniritsa zofunikira za muyezo.

Ntchito

Mafuta a I-40A amaonedwa kuti ndi mafuta apakati-kukhuthala, omwe amagwiritsidwa ntchito bwino pamakina odzaza kwambiri ndi makina pomwe zovuta zolumikizana zimayamba. Kusapezeka kwazinthu zina zapadera kumapangitsa kuti mafutawa azigwiritsidwanso ntchito ngati njira yochepetsera: mafuta otsika kwambiri (mwachitsanzo, I-20A kapena I-30A), komanso mafuta omwe amachulukirachulukira (mwachitsanzo, I-50A). ).

Kukhazikika kwabwino kwa okosijeni kumathandizira kuchepetsa nthawi yochepetsera zida ndi kukonza ndalama polimbikitsa ukhondo wamakina ndi kuchepetsa kusungitsa, kukulitsa moyo wamafuta ndi mafuta.

Kupititsa patsogolo chitetezo cha anti-wear and corrosion cha zigawo zamakina pogwiritsa ntchito mitundu yosiyanasiyana yokonza chizolowezi kumathandiza kukulitsa moyo wa zida zaukadaulo ndikuwonjezera magwiridwe antchito. Pakupanga, mafuta a I-40A amathandizidwa ndi ma demulsifiers, kotero mafutawa amateteza zida bwino kuchokera kumadzi kupita kumalo opaka.

Malo oyenera kugwiritsa ntchito mafuta a I-40A:

• Mikangano machitidwe, pamene pali chiopsezo kudzikundikira pamwamba madipoziti.
• Makina a hydraulic omwe amafunikira kuchuluka kwa katundu komanso chitetezo chovala.
• Makina ndi makina omwe amagwiritsidwa ntchito nthawi zonse m'malo owononga.
• Zida zogwirira ntchito zazitsulo zomwe zimagwira ntchito pazovuta zapamwamba.

Mafuta amadziwonetsera bwino ngati gawo lamadzimadzi ogwira ntchito mu makina opangira ma electroerosive azitsulo ndi aloyi.

Mtengo wamafuta am'mafakitale I-40A umatengera wopanga ndi kuyika kwa chinthucho:

• Mukanyamula migolo yokhala ndi malita 180 - kuchokera ku ma ruble 12700.
• Mukanyamula zitini zokhala ndi malita 5 - kuchokera ku ma ruble 300.
• Mukanyamula zitini zokhala ndi malita 10 - kuchokera ku ma ruble 700.
