Mafuta osungira K-17. Kodi kuyimitsa nthawi bwanji?
Zamkatimu
makhalidwe a
Chigawo chachikulu cha zosungirako K-17 ndi chisakanizo cha thiransifoma ndi mafuta oyendetsa ndege, omwe amawonjezera antifriction ndi antioxidant zowonjezera (makamaka petrolatum) ndi corrosion inhibitors. Mafuta a K-17 amatha kuyaka, kotero pogwira nawo ntchito, anthu ayenera kutsatira malamulo a chitetezo omwe amagwirizana ndi nyimbo zoterezi. Izi ndi monga kugwiritsa ntchito zida zosayambitsa moto, kugwira ntchito m'malo opumira mpweya wabwino, kupeŵa moto wapafupi wapafupi, komanso kugwiritsa ntchito zida zodzitetezera mokakamizidwa.
Zoyambira zakuthupi ndi zamakina:
- Kachulukidwe, kg / m3, kutentha kwa chipinda, osachepera: 900.
- Kinematic mamasukidwe akayendedwe, mm2/ s, pa kutentha kwa 100 °C: osachepera 15,5.
- Kuchuluka kwa kutentha, °C, osachepera: - 22.
- Kutentha koyaka moto osiyanasiyana, °C: 122…163.
- Zomwe zili pamwamba pa zonyansa zochokera kumakina,%: 0,07.
Mtundu wa mafuta atsopano a K-17 ndi wofiirira. Pakupanga kwake, mphamvu ya okosijeni yamafuta pazitsulo, chitsulo chosungunula ndi mkuwa imayenera kutsimikiziridwa. Zosiyana za dzimbiri (zofooka zofooka) zimaloledwa pakatha zaka 5 za kukhalapo kwa wosanjikiza wa mafutawa pagawo losungidwa. Ndioyenera kugwiritsidwa ntchito m'malo achinyezi komanso otentha, osagonjetsedwa ndi madzi a m'nyanja nthawi zonse. Kutengera momwe amagwirira ntchito, imayandikira mafuta a AeroShell Fluid 10 ochokera kunja.
Ntchito
Malo abwino kwambiri ogwiritsira ntchito mafuta osungira K-17 ndi awa:
- Kuteteza kwa nthawi yayitali m'nyumba zazitsulo zagalimoto.
- Kusungidwa kwa injini zamagalimoto zosungidwa.
- Kuphatikiza pamafuta opangira gasi amagalimoto othamanga kuti achepetse kuwonongeka kwawo komanso kuwonongeka kwa magawo amzere amafuta.
Pakusungidwa kwa nthawi yayitali kwa injini zamagalimoto, zosefera zonse zimachotsedwa kwa iwo, ndipo mafuta amapopedwa pagulu lonselo mpaka ma cavities atadzazidwa kwathunthu.
Kuyenerera kwa mafuta a K-17 kumatsimikiziridwa ndi kuthekera kwa okosijeni panthawi yosungidwa kwa nthawi yayitali. Kuphatikizika kwa masheya amafuta ndi zowonjezera kumakhudza kuchuluka kwa okosijeni, ndipo kukhalapo kwa chothira mumafuta kumatha kuwonjezera kuchuluka kwa kuwonongeka. Kuwonjezeka kwa kutentha kwa 10 ° C kumawirikiza kawiri kuchuluka kwa okosijeni, zomwe zimafupikitsa moyo wa alumali wamafuta moyenerera.
Mafuta oteteza K-17 sayenera kusakanikirana pafupipafupi: izi zimathandizira kupeza mpweya kumafuta. Pa nthawi yomweyi, malo okhudzidwa amawonjezeka, omwe amalimbikitsanso okosijeni. Njira za emulsification yamadzi kukhala mafuta zimakulitsidwanso, kupititsa patsogolo njira ya okosijeni. Choncho, posungira mafuta K-17 kwa zaka zoposa 3, makhalidwe ake ayenera kufufuzidwa kuti agwirizane ndi GOST 10877-76.
Mafuta otetezedwa omwe amafotokozedwa amapangidwa ku Russia ndi mabizinesi monga TD Synergy (Ryazan), OJSC Orenburg Oil and Gas Plant, komanso Necton Sea (Moscow). Mtengo wamafuta osungira K-17 umatsimikiziridwa ndi kuchuluka kwa kugula ndi kulongedza katundu. Mafutawo amapakidwa migolo yokhala ndi malita 180 (mtengo - kuchokera ku ma ruble 17000), komanso m'mabokosi okhala ndi malita 20 (mtengo - kuchokera ku ma ruble 3000) kapena malita 10 (mtengo - kuchokera ku ma ruble 1600). Chitsimikizo cha khalidwe loyenera la mankhwala ndi kukhalapo kwa chiphaso chochokera kwa wopanga.
