Kodi mungapange bwanji dizilo yozizira kuchokera ku dizilo yachilimwe?

Mavuto ndi Mayankho

Njira yosavuta ndiyo kusungunula chilimwe chotentha ndi palafini (izi ndi zomwe eni ambiri a mathirakitala ndi zonyamula katundu amachita). Chachiwiri, ngakhale njira yochepetsera ndalama ndikuwonjezera mafuta a biodiesel; kuchuluka kwake, malinga ndi akatswiri, ayenera kukhala osiyanasiyana 7 ... 10%.

Palinso matekinoloje otukuka kwambiri osinthira dizilo yachilimwe kukhala dizilo yachisanu, okhudzana ndi kugwiritsa ntchito ma antigel osiyanasiyana. Koma njira zoterezi sizitheka nthawi zonse m'mikhalidwe yabwino.

Pali njira zingapo zamakina kuti musavutike kuyambitsa injini nyengo yozizira:

• Kutsekereza hood.
• Kuyika chowotcha kutsogolo kwa thanki (izi sizitheka nthawi zonse pazifukwa zamapangidwe).
• Kusefukira kwamphamvu kwamafuta achilimwe kuchokera ku thanki imodzi kupita ku ina, zomwe zimachepetsa njira ya gelation.

Mndandanda wa ntchito

Choyamba, padzakhala kofunikira kuyesa kudziwa kuchuluka kwa zosefera. Pa kutentha pansi pa malo ogwiritsira ntchito bwino mafuta a dizilo a chilimwe, kuyesa kwa injini ya dizilo kumachitika, ndipo mawonekedwe a zosefera zamagalimoto amatsimikiziridwa ndi kukhazikika kwa ntchito yake. The ndondomeko phula komanso bwino anasiya ndi preheating zosefera.

Ndizothandiza kugwiritsa ntchito chowonjezera Stanadyne, chomwe:

1. Idzawonjezera nambala ya cetane ndi malo angapo.
2. Amaletsa kuzizira kwamafuta.
3. Idzayeretsa jekeseni ku zinyalala zosasungunuka ndi zinthu zotulutsa utomoni.
4. Zidzalepheretsa mapangidwe omatira pamwamba pazigawo zopaka, zomwe zingachepetse kuvala kwawo.

Chiŵerengero chowonjezera cha mafuta ndi 1: 500, ndipo n'zotheka kugwiritsa ntchito mitundu yosiyanasiyana ya zowonjezera za Stanadyne motsatizana, chifukwa zonse zimasakanikirana bwino. Tiyenera kukumbukira kuti zowonjezera izi zimatsimikizira emulsification yovomerezeka mpaka kutentha kosachepera -20.⁰Ndi komanso osagwiritsa ntchito nthawi yayitali (osapitirira sabata).

Mukhozanso kugwiritsa ntchito palafini luso, kuwonjezera pa chilimwe mafuta dizilo mu gawo zosaposa 1:10 ... 1:15. Komabe, izi siziyenera kubwerezedwa kupitilira katatu.

Kodi pali kusiyana kotani pakati pa chilimwe ndi nyengo yozizira?

Njira yoyamba ndikukhazikitsa sulfure weniweni wamafuta. GOST 305-82 amapereka mitundu itatu ya kalasi mafuta dizilo:

• Chilimwe (L), sulfure zomwe siziyenera kupitirira 0,2%.
• Zima (Z), zomwe kuchuluka kwa sulfure ndikwambiri - mpaka 0,5%.
• Arctic (A), zomwe zili ndi sulfure mpaka 0,4%.

Njira yachiwiri yosiyanitsa mafuta a dizilo ndi mtundu wake. Kwa chilimwe ndi mdima wachikasu, chisanu ndi mitundu ya arctic imakhala yopepuka. Malingaliro omwe alipo kuti mtundu wa mafuta a dizilo ukhoza kutsimikiziridwa ndi kukhalapo kwa bluish-buluu kapena mithunzi yofiira ndi olakwika. Yoyamba ikhoza kuwonedwa ndi mafuta atsopano, ndipo yachiwiri, m'malo mwake, yamafuta omwe asungidwa kwa nthawi yayitali.

Njira yodalirika yosiyanitsira magiredi amafuta ndikuzindikira kuchuluka kwawo komanso kukhuthala kwawo. Pamafuta a dizilo achilimwe, kachulukidwe kake kuyenera kukhala kosiyanasiyana kwa 850 ... 860 kg / m.³, ndipo kukhuthala kwake ndi osachepera 3 cSt. Makhalidwe a mafuta a dizilo yozizira - kachulukidwe 830 ... 840 kg / m³, kukhuthala - 1,6 ... 2,0 cSt.

Dizilo aundana? Kodi kuti amaundana m'nyengo yozizira dizilo. Mwachidule za zowonjezera dizilo, kuchepetsa mphamvu
