Iav roj yog tsim nyog rau lubricate hlau qhov chaw thiab bearings, raws li zoo raws li tiv thaiv lawv kev sib tsoo thaum lub sij hawm txav thiab, raws li, hnav. Nyob rau hauv ob qho tib si tsis siv neeg thiab phau ntawv kis tau tus mob, nws muab hydraulic siab thiab kev sib txhuam kom cov khoom sab hauv tuaj yeem ua lawv txoj haujlwm kom raug.
Cov roj muaj cov khoom sib txawv thiab cov khoom sib txawv, vim tias txhua qhov kev sib kis muaj qhov sib txawv ntawm lubrication. Vim li no, cov kua dej tau muab faib ua ntau hom:
- ntxhia;
- hluavtaws;
- semi-synthetic.
Cov ntxhia roj yog natural lubricants uas muaj ib tug sib tov ntawm hydrocarbons. Lawv yog cov khoom ntawm cov txheej txheem roj refining.
Lawv muaj qhov qis viscosity index: ntawm qhov kub siab heev lawv ua nyias thiab muab cov yeeb yaj kiab nyias nyias. Cov roj no yog cov pheej yig tshaj plaws.
Cov roj hluavtaws yog cov khoom siv ua kua uas tau ua kom huv thiab tawg siv cov khoom siv tshuaj. Vim li no, lawv kim dua, tab sis cov txiaj ntsig pom zoo rau cov nuj nqis. Cov roj no muaj qhov zoo thermal stability ua ntej kub kub: nws accumulates tsawg sludge, carbon los yog acids. Yog li ntawd, nws cov kev pab cuam lub neej yog nce.
Thiab qhov tsis muaj quav ciab txhais tau hais tias cov roj tsim nyog rau kev siv ntawm qhov kub tsis tshua muaj siab.
Semi-synthetic roj Kev ua haujlwm siab ua haujlwm hnyav automotive kis tau tus mob. Qhov no yog lub ntsiab lus kub - cov roj zoo dua li cov roj ntxhia thiab yuav raug nqi tsawg dua li hluavtaws. Nws muab cov qib kev ua tau zoo dua li cov roj ntshiab huv thiab tseem muaj txiaj ntsig zoo nrog lawv, ua kom nws haum raws li cov dej ntws los yog hloov pauv.
Ua ke nrog ib tus kws tshaj lij, peb tau npaj qhov qeb duas ntawm cov roj iav zoo tshaj plaws ntawm kev ua lag luam xyoo 2022.

Yuav xaiv iav roj li cas
Txhawm rau xaiv cov roj zoo rau koj, koj yuav tsum ntsuas qhov kev ua haujlwm ntawm lub tsheb, paub hom gearbox. Ua raws li cov ntaub ntawv no, koj tuaj yeem ua yam xyuam xim rau kev xaiv cov kua dej sib kis. Ua tib zoo saib rau ob yam tseem ceeb: viscosity Performance index ntawm cov roj thiab API kev faib tawm.
Classification ntawm iav roj
Cov roj iav muaj cov qib hauv qab uas txhais tau tias feem ntau ntawm lawv qhov zoo. Tam sim no, feem ntau ntawm lawv tau dhau los siv thiab tsuas yog GL-4 thiab GL-5 qib iav roj siv hauv cov tsheb niaj hnub. API kev faib tawm muab faib feem ntau los ntawm theem ntawm huab cua siab zog. Qhov siab dua ntawm GL pawg naj npawb, qhov zoo dua cov khoom ntxiv uas muab cov khoom no.
| HLW 1 | Cov chav kawm ntawm cov roj iav no yog tsim los ua haujlwm hauv cov xwm txheej yooj yim yam tsis muaj kev thauj khoom tshwj xeeb. Rau kev ua liaj ua teb machinery thiab tsheb thauj khoom. |
| HLW 2 | Cov khoom lag luam txheem tsim los rau cov tshuab xa hluav taws xob ua haujlwm hauv cov xwm txheej nruab nrab. Nws txawv ntawm GL-1 roj hauv cov yam ntxwv zoo dua los tiv thaiv kev hnav. Siv rau tib lub tsheb. |
| HLW 3 | Cov roj no yog siv rau hauv phau ntawv sib kis uas qhov zoo ntawm cov roj GL-1 lossis GL-2 yuav tsis txaus, tab sis lawv tsis xav tau cov khoom thauj uas cov roj GL-4 tuaj yeem ua tau. Lawv feem ntau yog siv rau phau ntawv sib kis uas ua haujlwm nyob rau hauv nruab nrab mus rau qhov hnyav. |
| HLW 4 | Tsim los rau cov chav sib kis nrog txhua hom qauv ntawm cov iav uas ua haujlwm nyob rau hauv nruab nrab thiab hnyav loads. Nws yog siv nyob rau hauv niaj hnub neeg nrog caij tsheb ntawm ntau yam. |
| HLW 5 | Cov roj siv hauv kev ua haujlwm hnyav, muaj ntau yam khoom siv ntxiv nrog phosphorus sulfur ntsiab hauv lub hauv paus. Siv rau tib lub tsheb li GL-4 |
Cov roj iav kuj tuaj yeem raug cais raws li viscosity index. Hauv qab no yog ib lub rooj ntawm cov yam ntxwv tshwj xeeb thiab kev siv:
| Index | Index decryption |
| 60, 70, 80 | Cov roj nrog qhov ntsuas no yog lub caij ntuj sov. Lawv tsim nyog rau thaj tsam yav qab teb ntawm Peb Lub Tebchaws. |
| 70W, 75W, 80W | Winter are designated by such an index. They are recommended for use in the north of the Federation, in areas with low temperatures. |
| 70W-80, 75W-140, 85W-140 | Txhua huab cua roj muaj qhov ntsuas dual. Cov kua dej zoo li no yog universal, lawv raug pom zoo siv rau hauv nruab nrab ntawm lub tebchaws. |
