Mafuta a B-70. Mafuta oyendetsa ndege azaka zapitazi

Features wa zikuchokera ndi katundu

Mafuta a B-70 amadziwika ndi:

• Kupanda zowonjezera tetraethyl lead, zomwe zimapangitsa kuti zikhale zotetezeka momwe zingathere kwa chilengedwe.
• Chizindikiro cha nambala ya octane, yomwe imathandizira kukakamiza koyatsa.
• Kawopsedwe kakang'ono ka nthunzi, zomwe sizifuna kupangidwa kwapadera, zokwera mtengo kwambiri zosungirako zotetezeka.

The zikuchokera mafuta monga ano zimalimbikitsa hydrocarbon ndi isomers awo, benzene ndi mankhwala ake processing, komanso onunkhira mankhwala alkyl. Zinthu zochepa za sulfure ndi utomoni zimaloledwa, zomwe sizidutsa 2,1% yonse.

The katundu waukulu wa ndege mtundu mafuta B-70:

1. Kachulukidwe, kg / m³ pa kutentha kwa chipinda: 750.
2. Kutentha kwa chiyambi cha ndondomeko ya crystallization, ⁰C, osati pansi: -60.
3. Nambala ya Octane: 70.
4. Kuthamanga kwa nthunzi, kPa: 50.
5. Kutalika kwa nthawi yosungirako popanda delamination, h, osachepera: 8.
6. Mtundu, fungo - palibe.

Gwiritsani ntchito

Mafuta a B-70 adapangidwa kuti azigwiritsidwa ntchito kwambiri mu injini za ndege za pisitoni. Pakalipano, gawo la kugwiritsa ntchito bwino kwa ndege za piston poyendetsa ndege latsika kwambiri. Choncho, mafuta opangidwa amagwiritsidwa ntchito kwambiri monga zosungunulira zapadziko lonse, izi zimathandizidwa ndi makhalidwe awa:

• Amasanduka nthunzi mwachangu kuchokera pamalo aliwonse, osasiya madontho pamenepo.
• Kudalira kochepa pa kusintha kwa kutentha, komwe kumakhalabe ngakhale kutentha koipa kwa mpweya wakunja.
• Homogeneity ya mankhwala zikuchokera, kulola kusungidwa kwa nthawi yayitali (malinga ndi kutentha kofunikira, chinyezi chachibale komanso mpweya wabwino.

Ma GOST omwe alipo amafuta oyendetsa ndege ali ndi udindo waukulu wamafuta, omwe ali ndi zowonjezera zotsutsana ndi kugogoda. Izi sizikugwira ntchito kwa mafuta a B-70, ndipo ntchito yake ya chilengedwe ndiyokwera kwambiri kuposa mafuta oyendetsa ndege amtundu wina.

Tekinoloje yogwiritsira ntchito mafuta a B-70 ngati zosungunulira

Ndi zabwino zake zonse, mafuta oyendetsa ndege ngati zosungunulira amalimbikitsidwabe kugwiritsidwa ntchito mosamala kwambiri. Chifukwa cha ichi chimaonedwa kuti ndi kuchepa kwakukulu kwa chinyezi cha khungu, kulowetsedwa kwathunthu kwa zigawo za mafutawa mu ziwalo zamkati. Choncho kugwiritsa ntchito magolovesi olimbana ndi mphira a asidi kumalimbikitsidwa kwambiri. Chofunika kwambiri cholepheretsa ndi kukhalapo kwa zowonjezera zotsutsana ndi icing mu mafuta, zomwe zimakhala ngati mutagen.

Kugwiritsa ntchito mafuta a B-70 poyeretsa zodetsa zamafuta kumadzilungamitsa pokhapokha ngati mukugwira ntchito ndi zida zaukadaulo zovuta kuzifikitsa, pomwe kusakhazikika kwakukulu kwamafuta oyendetsa ndege kumathandizira kuti apereke mwachangu kumalo aliwonse. Kuchita bwino kwa zosungunulira kumawonjezeka ngati kukhuthala kwa filimu yamafuta kuchotsedwa pamwamba kumachepetsedwa. Zatsimikiziridwa kuti, poyerekeza ndi mafuta omwe amagwiritsidwa ntchito mofananamo (mwachitsanzo, mafuta a Kalos, kapena Kallos, pambuyo pa katswiri wa zamankhwala wa ku Hungary yemwe poyamba anapempha kuti izi zigwiritsidwe ntchito ngati zosungunulira), B-70 imasungunula bwino zowonongeka zowonongeka ndipo zimafunikira zochepa. mpweya zoletsa malo kumene ntchito yotere ikuchitika.

Mtengo pa tani

Mitengo yazinthuzi ndi yosakhazikika, choncho ogulitsa ambiri amakonda kugwira ntchito pamsika muzokambirana zamtengo wapatali. Koma, mulimonse, mtengo umadalira kuchuluka kwa zomwe zachitika komanso njira yopangira ma CD:

• Kuyika mu chidebe chokhala ndi lita imodzi - kuchokera ku ma ruble 1.
• Kuyika mu migolo ya 200 l - 6000 rubles.
• Kwa ogula ogulitsa - kuchokera ku ma ruble 70000 pa tani.
