Cov yam ntxwv ntawm cov kua nres los ntawm Lukoil
Nta
Cov kev cai tseem ceeb rau cov dej nres yog kev ruaj ntseg ntawm lawv cov thermophysical tsis nyob rau hauv qhov dav tshaj qhov kub thiab txias thiab tsis muaj teeb meem cuam tshuam rau ntawm qhov nres ntawm lub tsheb. Tus thawj ntawm Lukoil DOT-4 - "troika" - tau yoog rau lub nruas-hom nres tshuab, thiab tau siv los ntawm cov tswv ntawm cov tsheb tsim hauv tsev. Yog li ntawd, nyob rau hauv cov ntaub ntawv no, kev hloov mus rau ib tug tshiab kua yog tsim los xaiv. Lwm yam yog lub tsheb nrog disc nres: vim lawv cov kev ua tau zoo hauv kev sib tsoo, lawv ua kom sov ntau dua, thiab DOT-3, muaj qhov kub ntawm qhov tsuas yog 205. °C, nws puas phem.
Txoj kev tawm tau pom nyob rau hauv kev hloov lub ntsiab tivthaiv - es tsis txhob ntawm ib txwm glycol nyob rau hauv DOT-4, ib tug sib tov ntawm esters thiab boric acid tau siv. Cov khoom tseem ceeb ua rau muaj qhov nce hauv qhov kub siab (txog 250 °C), thiab boric acid stabilizes qhov kev ua tau zoo thiab tiv thaiv cov tsos ntawm cov dej molecules nyob rau hauv cov muaj pes tsawg leeg ntawm tus nres (qhov no yog ua tau nyob rau hauv lub sij hawm ntev ntawm lub tsheb thiab nyob rau hauv high humidity). Nyob rau tib lub sijhawm, tsis yog ib qho lossis lwm yam kev tivthaiv yog suav tias yog kev puas tsuaj ib puag ncig, yog li ntawd, Lukoil DOT-4 nres cov kua dej tsis muaj tshuaj lom thaum nws ua. Txhua yam ntxiv - tshuaj tiv thaiv ua npuas ncauj, tshuaj tua kab mob, tshuaj tiv thaiv corrosion, raws li qhov kev xeem tau, tau txav los ntawm "peb" mus rau "plaub", txij li qhov ua tau zoo ntawm cov khoom tau lees paub tseeb.
Lub ntuj tsis zoo ntawm cov ntsiab lus tshiab yog nws cov nqi siab dua, uas cuam tshuam nrog kev teeb meem thev naus laus zis hauv kev npaj ntawm esters. Cov tswv ntawm lub tsheb nrog disc nres tsuas yog cia siab tias dhau sijhawm, Lukoil yuav pom txoj hauv kev siv sijhawm tsawg dua los ua kom cov khoom noj khoom haus.
Xyuas
Kev txheeb xyuas cov neeg siv khoom, peb tuaj yeem kos cov lus xaus hauv qab no:
- Txawm hais tias qhov zoo sib xws ntawm cov qauv tsim, nws tsis pom zoo kom sib tov DOT-3 thiab DOT-4 hauv tib lub nres nres. Sij hawm dhau mus, cov ntaub ntawv los nag, uas, yog tias tsis pom raws sijhawm, yuav ua rau muaj ntau yam teeb meem, txij li kev ntxuav ntawm qhov chaw mus rau banal jamming ntawm lub brakes nrog cov tsos ntawm cov yam ntxwv tsw. Pom tau tias, qee yam tshuaj lom neeg sib cuam tshuam ntawm ethylene oxide thiab ether tseem tshwm sim.
- Lukoil DOT-3 tuav lub sijhawm lav 4 xyoos. Muab qhov nruab nrab kub ntawm qhov chaw nres tsheb, qhov no tsis yog qhov phem.
- Kuj tsis muaj qhov cuam tshuam tsis zoo rau lub xeev ntawm qhov chaw ntawm lub tshuab nres, piv txwv li, corrosion inhibitors ua lawv lub luag haujlwm kom raug.
- Feem ntau cov tswv tsheb hauv lawv cov kev tshuaj xyuas qhia tias qhov zoo ntawm Lukoil DOT-4 yog nyob ntawm cov chaw tsim khoom. Nres kua, uas yog tsim nyob rau hauv Dzerzhinsk, yog zoo dua li qub DOT-4, tab sis ua nyob rau hauv Obninsk. Cov kws tshaj lij hais tias yog vim li cas tsis txaus niaj hnub no (raws li kev tau txais cov lus piav qhia ntawm cov dej nres) tsim los ntawm kev lag luam.
Muaj ntau ntau cov lus xaus: qhov muaj pes tsawg leeg ntawm Lukoil DOT-4 yog qhov zoo, thiab tag nrho cov additives tshaj tawm los ntawm cov chaw tsim tshuaj paus tiv thaiv lawv cov dej num. Nws yog qhov tseeb tias ib tus neeg yuav tsum nco ntsoov paub txog qhov toxicity thiab flammability ntawm cov kua nres, thiab thaum tuav lawv, ua raws li txhua yam kev ceev faj. DOT-4 yog tsis muaj kev zam.
Tus nqi ntawm Lukoil DOT-4 nres kua yog los ntawm 80 rubles. rau ib lub thoob ntim ntawm 0,5 litres. thiab los ntawm 150 rubles. rau 1 liter canister.
