Lub cev muaj zog, nyob ntawm cov tshuaj muaj pes tsawg leeg, muab faib ua ntxhia, hluavtaws thiab semi-synthetic.

Hom roj nplua nyeem rau lub cav tsheb

Cov roj ntxhia yog cov roj av tseem ceeb uas tau ua kom zoo me ntsis tom qab nws tau mined. Cov roj no ruaj khov thiab pheej yig heev. Tsis tas li ntawd, cov tshuab muaj hnub nyoog tshaj tsib xyoos tseem yuav nyiam cov khoom siv ntxhia.

Cov roj hluavtaws yog tsim nyob rau hauv lub chaw soj nstuam siv cov qauv tshuaj tshwj xeeb. Lawv tsis tshua nyob ntawm lwm yam, ua rau lub cav hnav tsis kam thiab txuag roj noj.

Semi-synthetic roj tau txais los ntawm kev sib xyaw ua ke ntawm cov khoom siv yav dhau los. Tam sim no lawv yog tus thawj coj ua lag luam uas tsis muaj kev sib cav.

Txhua hom roj nplua nyeem muaj nws lub voj voog ntawm cov neeg qhuas. Qhov kev xaiv tsuas yog nyob ntawm qhov mais ntawm lub tsheb thiab qhov kub thiab txias ntawm ib puag ncig.

Puas yog nws tuaj yeem sib xyaw semi-synthetics thiab hluavtaws? Tom qab tag nrho, tej zaum yuav muajMuaj ntau yam xwm txheej ntawm txoj kev, piv txwv li, qee zaum yuav tsum tau sau cov roj sai sai, tab sis txoj cai tsuas yog tsis muaj.

Kev sib xyaw roj sib txawv: kev xav rau thiab tawm tsam

Muaj cov ntsiab lus ntawm lub ntsiab lus ntawm cov tuam txhab thiab cov neeg tsav tsheb ntawm cov lus nug: nws puas tuaj yeem sib xyaw cov roj sib txawv? Kev sib xyaw roj muaj nws qhov zoo thiab qhov tsis zoo.

Cov neeg tawm tsam hais tias cov roj sib txawv tsis yog tsim los xwb. Lawv twb muaj cov qauv tshuaj zoo tshaj plaws, thiab nws txoj kev ua txhaum cai yuav tsis ua rau muaj txiaj ntsig zoo.

Cov neeg ua raws li qhov kev xav ntawm qhov tsis sib xws tsis yog qhov tsis txaus ntseeg thiab teb zoo rau cov lus nug txog seb nws puas tuaj yeem sib xyaw cov khoom siv hluav taws xob thiab cov khoom siv hluavtaws, nrog rau cov hluavtaws thiab cov roj ntxhia. Qhov no tau piav qhia los ntawm qhov tseeb tias cov khoom siv hluav taws xob semi-synthetic twb yog cov khoom sib xyaw, ntau tshaj li ib nrab ntawm cov muaj pes tsawg leeg uas yog cov pob zeb hauv av. Thiab tsis muaj dab tsi phem tuaj yeem tshwm sim yog tias cov khoom siv hluavtaws ntau dua, ua kom huv thiab ua tiav, ntxiv rau qhov sib tov.

Cov kws tshaj lij feem ntau yog nruab nrab. Thiab rau cov lus nug hais txog yuav ua li cas hloov cov roj cav, nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom siv hluavtaws, feem ntau koj yuav tau txais cov lus teb zoo, tab sis nrog qee qhov tshwj xeeb.

Yuav ua li cas muab cov roj kom raug?

Tsis yog txhua lub roj nplua nyeem raug pom zoo rau kev sib xyaw. Nws yog qhov ua tau heev uas yuav tsis muaj qhov tsis zoo tshwj xeeb rau lub cev muaj zog, tab sis tseem qhov no yog qhov kev ntsuas tsis txaus ntseeg, thiab nws yuav muaj txiaj ntsig zoo.ua raws li qee txoj cai thaum sib xyaw cov roj, tshwj xeeb tshaj yog tias koj tuaj yeem xaiv qhov kev xaiv maj mam dua.

Kev sib xyaw roj los ntawm cov tuam txhab sib txawv

Kuv puas tuaj yeem sib xyaw cov roj hluavtaws thiab semi-synthetic los ntawm cov tuam txhab sib txawv?

Qhov zoo tshaj plaws, nws yog qhov zoo dua los muab cov roj ntawm tib hom. Qhov no yog vim muaj cov txheej txheem zoo sib xws ntawm cov tshuaj ntxiv thiab cov tshuaj zoo sib xws. Lubricants yeej yuav tsis sib tw nrog ib leeg thiab yuav kav ntev mus txog rau thaum hloov tom ntej.

Yog li, nws yog qhov zoo dua los siv cov roj nplua nyeem los ntawm tib lub chaw tsim khoom. Tab sis txij li thaum, vim tsis muaj kev xaiv ntawm cov roj ntawm tes, cov lus nug ntawm seb puas muaj peev xwm sib tov hluavtaws thiab semi-synthetics tshwm sim heev, niaj hnub manufacturers tau pom ib txoj kev tawm.

Cov tuam txhab roj feem ntau niaj hnub no ua tau raws li API thiab ACEA cov qauv, uas tso cai rau lub peev xwm los txuas cov khoom rau ib leeg. Yog li ntawd, los ntawm kev sib xyaw cov roj nplua nyeem uas ua tau raws li cov qauv no, koj tuaj yeem zam qhov tsis zoo rau kev ua haujlwm ntawm koj lub cav, tab sis nws raug nquahu kom ua qhov no tsuas yog tshwj xeeb xwb.

Roj hloov raws li kev ua tau zoo thiab qib viscosity

Puas yog nws tuaj yeem sib xyaw roj - hluavtaws nrog semi-synthetics yog tias lawv txawv qib thiab sib txawv viscosities?

Cov neeg tsim khoom tsis pom zoo kom hloov cov qib thiab cov viscosity ntawm cov roj, tab sis yog tias qhov no tsim nyog, nws yog qhov zoo dua los siv tib lub npe raws li yav dhau los.

Yog chav kawm qis dua, nws raug nquahu kom yaug txhua yamcav qhov chaw. Nws raug nquahu kom taug kev me ntsis hauv hom nruab nrab, ua ntej sau nrog tshuaj ntxuav.

Txoj kev sib xyaw roj

Yuav ua li cas thaum koj sib tov hluavtaws thiab semi-synthetics? Xaiv cov tuam ntxhab zoo, koj tsis tuaj yeem ntshai ntawm qhov ua tsis tiav loj hauv kev ua haujlwm ntawm lub cev muaj zog. Yog tias koj tau yuav cov roj thiab tsis paub tseeb ntawm nws, nws raug nquahu kom ua qhov kev sim. Los ntawm kev sib xyaw cov khoom hauv qhov me me, koj tuaj yeem ua kom sov rau lawv thiab ua raws li cov tshuaj tiv thaiv. Yog tias muaj cov ntaub ntawv nag lossis daus tshwm sim, cov tshuaj no tsis tuaj yeem ua ke.

Thaum tsis muaj qhov tsis sib haum xeeb ntawm cov khoom, koj tuaj yeem sib xyaw cov roj cav no kom nyab xeeb. Yuav ua li cas sib tov hluavtaws thiab semi-synthetics ntawm txawv viscosities thiab dab tsi yuav tshwm sim thaum kawg?

Raws li tau hais los saum toj no, cov roj nplaum ntawm cov viscosities sib txawv tuaj yeem sib xyaw, tab sis nws yog qhov zoo dua los siv tib hom. Yog li, yog tias koj sib tov cov khoom, koj yuav tau txais kwv yees li qhov nruab nrab. Piv txwv li, yog tias koj muab 5w-50 cov khoom siv hluavtaws thiab 15w-30 semi-synthetics hauv qhov sib npaug, 10w-40 roj yuav tawm los.

Cov lus nug ntawm seb puas tuaj yeem sib xyaw cov khoom siv hluav taws xob thiab cov khoom sib txuas ntawm cov chav kawm sib txawv tau teb los saum toj no. Raws li qhov sib xyaw ua ke no, cov roj ntawm cov khoom qis dua yuav tau txais. Piv txwv li, thaum sib tov roj ntawm chav H thiab L, peb yuav xaus nrog cov chav kawm qis - H.

Muaj peev xwm tsis zoo ntawm kev sib txuas

Qhov sib txawv hauvchemical formula, sib txawv ntawm additives tej zaum yuav muaj teeb meem nrog ib leeg thaum lub sij hawm ua hauj lwm. Txawm hais tias koj tau sim sib xyaw cov roj me me, qhov no tsis tau lees tias qee qhov teeb meem yuav tsis tshwm sim los ntawm kev siv cov sib tov.

Yog tias koj tab tom ntsib teeb meem ntawm seb puas tuaj yeem sib xyaw cov khoom siv hluav taws xob thiab cov khoom sib xyaw, yog tias tsis muaj lwm txoj hauv kev, qhov no tuaj yeem ua tiav, tab sis txuas ntxiv nws pom zoo kom tseem siv cov roj qub.

Raws li qhov tshwm sim ntawm kev rov qab sib xyaw ntawm cov roj los yog tau txais cov khoom cuav, lossis nrog qhov sib txawv loj hauv cov tshuaj formula, deposits thiab slags tuaj yeem tsim hauv lub cav. Qhov no ua rau kom ceev ceev ntawm lub cev muaj zog thiab txo qis hauv nws lub neej kev pab cuam.

Yog tias koj noj ib qho roj tsawg dua 15%, ces nws yuav tsis muaj kev phom sij rau lub cav. Cov khoom siv no tseem nyob hauv lub tsheb txawm tias muaj kev hloov pauv yooj yim ntawm cov roj nplua nyeem.

Cov roj ntxhia thiab muaj peev xwm ntawm lawv ua ke nrog lwm hom roj

Kuv puas tuaj yeem sib xyaw hluavtaws thiab ntxhia? Lo lus nug no txhawj xeeb ntau tus neeg tsav tsheb uas siv cov roj ntsha ntuj.

Nws tau tso cai los ua ke cov khoom siv hluavtaws raws li polyalphaelins (PAO) nrog cov roj ntxhia.

Lwm yam khoom siv hluavtaws ua ke nrog cov ntxhia tsis zoo. Yog li ntawd, nws yuav muaj feem cuam tshuam nrog cov neeg sawv cev ntawm cov chaw tsim khoom lossis tsawg kawg nrog cov kws tshaj lij ntawm cov chaw pabcuam txog qhov muaj peev xwm ntawm qhov sib tov.

Tsawg pheej hmoo roj ntxhia rojtuaj yeem tov nrog semi-synthetics.

Zoo kawg

Synthetics thiab semi-synthetics. Cov roj no puas tuaj yeem sib xyaw? Cov lus teb rau lo lus nug no yog yog, tab sis thaum txuas, koj yuav tsum nco ntsoov cov kev cai yooj yim:

• nws yog qhov zoo dua los siv cov roj ntawm tib lub chaw tsim khoom, tib lub viscosity thiab chav kawm;
• thaum hloov cov chav kawm ntawm cov khoom siv, siv ib hom ntawm cov khoom, qhov no yuav txo tau qhov tshwm sim tsis zoo rau lub cev muaj zog, thaum chav kawm ntawm cov khoom sib xyaw ntawm cov zis yuav qis dua;
• nrog cov viscosity sib txawv ntawm cov roj, kuj sim coj cov khoom ntawm tib hom, qhov kawg viscosity yuav nyob ntawm seb cov khoom sib faib;
• tsis tshua muaj thiab tsis xav tau yog kev hloov pauv ntawm ib lub chaw tsim khoom mus rau lwm qhov, ua ntej nws yog qhov zoo dua mus ntsib tus kws tshaj lij;
• sim coj cov khoom zoo uas ua tau raws li cov kev cai ntawm Asmeskas thiab European cov qauv zoo;
• Siv lub tshuab ntxuav ua ntej siv roj.

Cov roj ntxhia kuj tuaj yeem sib xyaw nrog lwm cov khoom, tab sis feem ntau qhov no tsis xav tau.
