Nigrol. Bambo wamafuta amagetsi amakono

General makhalidwe ndi ntchito

Traditional nigrol yakhala ikugwiritsidwa ntchito kwambiri m'mbuyomu ngati mafuta opangira mafuta opangira zida zolemetsa zotsatiridwa ndi mawilo, komanso zida zosuntha za nthunzi, zomwe nthawi zonse zimakumana ndi nthunzi komanso kutentha kwambiri. Malinga ndi GOST 542-50 (potsirizira pake inathetsedwa mu 1975), nigrol inagawidwa mu "chilimwe" ndi "dzinja" - mitunduyo inali yosiyana mu magawo a viscosity, chifukwa "chilimwe" nigrol inali yokwera, kufika 35 mm.²/Ndi. Mafuta oterowo adatsanuliridwa mu ma axles a magalimoto ndipo amagwiritsidwa ntchito kwambiri m'magiya: katundu wolumikizana ndi magalimoto panthawiyo anali otsika.

Mtengo waukulu wa nigrol umakhala mu kuchuluka kwa zinthu zotulutsa utomoni zomwe zimapezeka m'magawo ena amafuta. Izi zimapangitsa kuchuluka kokwanira kwamafuta azinthu izi.

Nigrol yamakono: zosiyana

Kuvuta kwa magwiridwe antchito a zida zamakono zoyendera zidapangitsa kuchepa kwa magwiridwe antchito a nigrol wamba, popeza kunalibe zowonjezera zoletsa, komanso kukhuthala kwamphamvu kunapangitsa kuti katundu azichulukirachulukira pa zinthu zotumizira. Makamaka magiya a hypoid komwe kutayika kwa mikangano kumakhala kwakukulu. Choncho, tsopano lingaliro la "nigrol" ndi chizindikiro chokha, ndipo chizindikiro ichi nthawi zambiri chimatanthauza mafuta opatsirana monga Tad-17 kapena Tep-15.

makhalidwe a

Nigrol Tad-17 ndi mtundu wa mafuta zida zamagalimoto, zomwe ndi:

1. Kuchuluka kukana kutsetsereka kukangana pa nkhani ya kusiyana kwambiri liwiro la kukhudzana zinthu za makina HIV.
2. Kukhalapo kwa zowonjezera zomwe zimatsimikizira kukhalapo kosalekeza ndi kukonzanso filimu yapamwamba ya mafuta.
3. Zing'onozing'ono (poyerekeza ndi ma nigrols wamba) mtengo wa viscosity wachibale.
4. Kuchepetsa kudalira mamasukidwe akayendedwe pa kutentha kumene kumachitika kukhudzana zone.

Zowonjezera zili ndi sulfure, phosphorous (koma osati kutsogolera!), Anti-foam zigawo zikuluzikulu. Nambala pambuyo kalata chidule limasonyeza mamasukidwe akayendedwe a lubricant, mm²/s, zomwe malonda ali ndi 100^ºC.

Lubricant ntchito ikuwonetsedwa pansipa:

• kukhuthala kwapakati, mm²/ s, osapitirira - 18;
• kutentha kwa ntchito, ^ºC - kuchokera -20 mpaka +135;
• mphamvu zogwirira ntchito, makilomita zikwi - mpaka 75 ... 80;
• kuchuluka kwa ntchito - 5.

Pansi pamavuto, GOST 17479.2-85 imatengera kupanikizika kwambiri, kugwiritsiridwa ntchito kosiyanasiyana, kutha kugwira ntchito molumikizana ndi katundu mpaka 3 GPa ndi kutentha kwanuko pakukhazikitsa mayunitsi mpaka 140 ... 150^ºC.

Magawo ena a Tad-17 amayendetsedwa ndi GOST 23652-79.

Mafuta amtundu wa Nigrol Tep-15 ali ndi mamasukidwe otsika, kotero kuti mphamvu zotumizira mafuta zomwe zimagwiritsidwa ntchito ndizokwera kwambiri. Kuonjezera apo, ubwino wa mafuta awa ndi awa:

1. Kuchita bwino kwa anti-corrosion.
2. Kukhazikika kwamakayendedwe pamitundu yosiyanasiyana ya kutentha.
3. Kuwongolera kwabwino kwa distillate yoyamba, yomwe imawonetsetsa kuti zonyansa zamakina zizipezeka mumafuta (osapitirira 0,03%).
4. Kusalowerera ndale kwa pH index, komwe kumalepheretsa mapangidwe a foci pakuyika panthawi yopatsirana.

Panthawi imodzimodziyo, zizindikiro zenizeni za mphamvu zotsutsana ndi kuvala za mafuta a gear zimasungidwa mokwanira pa kutentha kochepa. Choncho, kuthamanga kwa kayendedwe ka magawo odzola kuyenera kukhala kochepa. Izi zimawonedwa makamaka pamagalimoto omwe amagwiritsidwa ntchito pafupipafupi (mathirakitala, ma cranes, ndi zina).

Zizindikiro zogwiritsira ntchito mafuta:

• kukhuthala kwapakati, mm²/ s, osapitirira - 15;
• kutentha kwa ntchito, ^ºC - kuchokera -23 mpaka +130;
• mphamvu zogwirira ntchito, makilomita zikwi - mpaka 20 ... 30;
• kuchuluka kwa ntchito - 3 (kukhudzana ndi katundu mpaka 2,5 GPa, kutentha kwanuko m'malo okhazikika mpaka 120 ... 140^ºC).

Magawo ena a Nigrol Tep-15 amayendetsedwa ndi GOST 23652-79.

Nigrol. Mtengo pa lita

Mtengo wamafuta otumizira amtundu wa Nigrol umatsimikiziridwa ndi zinthu zingapo, kuphatikiza:

1. Kapangidwe ka gearbox yamagalimoto.
2. Kutentha osiyanasiyana ntchito.
3. Nthawi ndi kuchuluka kwa zogula.
4. Kukhalapo ndi zikuchokera zina.
5. ntchito ndi nthawi yowonjezera.

Mitundu yosiyanasiyana ya mitengo ya nigrol ndi yodziwika, kutengera kuyika kwamafuta:

• mu migolo ya 190 ... 195 makilogalamu - 40 rubles / l;
• mu zitini 20 L - 65 rubles / l;
• mu zitini za 1 lita - 90 rubles / lita.

Chifukwa chake, kuchuluka kwa zogula (ndi mtengo wazinthu) kumatsimikiziridwa ndi kukula kwagalimoto yanu, popeza kusintha mafuta munyengo yanthawi yayitali sikungapeweke.

Nigrol, ndi chiyani ndipo mungagule kuti?
