Hom iav roj thiab lawv cov yam ntxwv. Kev siv cov iav roj
Lubrication khoom yuav tsum tau rau kis tau tus mob mechanisms, tsis txaus siab rau tshwj xeeb mloog. Roj nyob rau hauv cov iav thawv yog tsis hloov raws li feem ntau raws li nyob rau hauv lub engine. Roj rau kis tau tus mob - ib tug lubricating cov khoom uas nws lub ntsiab muaj nuj nqi yog tsim tau ib cov kev tiv thaiv zaj duab xis nyob rau txhua iav mechanism kis tau tus mob, hloov thawv, axles thiab differentials. Nrog rau lub cev muaj zog yog ntau dua los yog tsawg ntshiab. Cia xyuas hom iav roj thiab lawv cov yam ntxwv. Qhov no yog heev pab tau cov ntaub ntawv rau novice tsheb tswv.
lus qhia dav dav
Tsis hais txog ntawm lub hom ntawm cov roj rau cov kis ntawm cov khoom raws li nyob rau hauv lub Extract tau nyob rau hauv hnyav refined roj lubricants. Tsis tas li ntawd no ntxiv ib ntau yam ntawm cov khoom, distillates thiab additives. Lub hauv paus ntawm yav dhau los yog feem ntau phosphorus, sulfur, molybdenum disulphide thiab lwm yam zoo xws tshuaj.
Yog vim li cas kis tau tus mob roj
Peb tau pom tias luv luv, yog vim li cas qhov yuav tsum tau rau lubrication ntawm cov kis system. Cov khoom yuav tsum txo kev sib txhuam thaum lub sij hawm kev lag luam ntawm lub zog thiab lwm yam mechanisms. Los ntawm kev siv ntawm lubricants yog significantly txo coj ntawm kis tau tus mob qhov chaw, txo zog losses vim kev sib txhuam. Vim tus ntsoos ntsoos dhau heev lawm thaum tshav kub kub roj on cov ntsiab lus. Phab ntawm lub zog thiab mechanisms muaj kev tiv thaiv los ntawm corrosion. Txawv teb chaws siv lawv cov roj. Tsis tas li ntawd, lawv cov dej num nyob rau hauv ntau txoj kev.
Lavxias teb sab txheem
Hom iav roj thiab lawv cov kev kawm nyob rau hauv Russia yog nruj me ntsis tswj los ntawm GOST tseem Soviet lub sij hawm. Raws li lub ntsiab daim ntawv uas Txoj kev no muaj tag nrho cov ntaub ntawv nyob rau hauv cov roj nplua nyeem rau cov kis Cheebtsam thiab cov rooj sib txoos siv GOST 17479.2-85. Qhov no tus txheej txheem muab rau plaub pab pawg txog lubricants. Lawv txawv nyob rau hauv viscosity - nws yog 9, 12, 18 thiab 34.
Iav roj, lawv cov qhab nia thiab cov yam ntxwv yuav tau muab faib mus rau hauv tsib lub ntsiab pawg. Thawj - nws yog cov khoom, raws li ib feem ntawm cov uas muaj muaj tsis muaj additives. Nyob rau hauv lwm cov pab pawg, cov Cheebtsam yog tso cai. Efficiency thiab cov yam ntxwv ntawm additives tsub kom raws li zoo raws li cov pab pawg neeg tooj. Lub tsib qeb muaj xws li roj ntau yam ntawm daim ntawv sau npe.
Cov thawj pab pawg neeg
Qhov no hauv chav kawm ntawv muaj xws li cov ntaub ntawv uas muaj xws li tsuas mineral Cheebtsam, thiab lawv tsis muaj additives. Cov lubricants yog tsim los siv nyob rau hauv cab zog, conical, cylindrical. Tau ua ntej tiv tauj load - los ntawm 900 txog 1,500 MPa ntawm ib tug kub mus txog 90 degrees.
Qhov thib ob pab pawg neeg
Nws kuj raws li nyob rau ntxhia roj, tab sis lawv muaj ib tug ntau yam ntawm additives uas tiv thaiv tiv thaiv coj ntawm Cheebtsam. Cov qhab nia iav roj thiab lawv cov yam ntxwv yog haum rau siv nyob rau hauv lub cab, cylindrical, thiab lwm yam zog qhov twg cov kev sib cuag load nqi rau 2100 MPa ntawm kub txog li 130 degrees.
Qhov thib peb pab pawg neeg
Qhov no mineral roj nrog EP additives. Additives nyob rau hauv cov khoom ua mob pesnrab. Cov lubricants siv nrog kauv-canonical transmissions cylindrical Hypoid. Ntawm no, cov kev txwv load txog li 2500 MPa, thiab qhov kub thiab txias nce mus txog 150 degrees.
Qhov thib plaub pab pawg neeg
Qhov no cov roj uas muaj EP additives uas muaj kev txiav txim. Lawv yog npaj rau kis tau tus mob, qhov chaw uas lub limiting load tsis pub tshaj 3000 MPa ntawm ib tug tshaj plaws kub ntawm 150 degrees. Ib tug ntawm lawv cov neeg sawv cev - ib tug iav "Lukoil" roj uas nws yam ntxwv ua rau lawv tsim rau neeg caij tsheb.
Lub tsib pab pawg neeg
Qhov no universal lubricant khoom, uas muaj tej pob khoom ntawm universal additives. Feem ntau, lawv yog multifunctional. Reserve hu load yog tsis ntau tshaj li 3000 MPa, thiab lub siab tshaj plaws kub yog tsis ntau tshaj 150 degrees.
Raws li cim zos khoom
Hom iav roj thiab lawv cov yam ntxwv nyob rau hauv ib tug tshwj xeeb encrypted code. Nws zoo raws li nram no: TM-5-9 (3). Muaj TM hais tias cov khoom no yog ib cov roj rau transmissions. Daim duab 5 qhia hais tias qhov no multi-functional khoom uas EP additives. Qhov tseem ceeb 9 thiab 3 qhia hais tias ib tug cov ntaub ntawv uas nrog ib tug tsawg viscosity thiab cov ntsiab lus ntawm gelling additive.
Yam dab tsi yuav tsum tau muaj ib lub iav roj
Niaj hnub no, siv ib tug ntau yam ntawm kis tau tus mob mechanisms nrog lawv hom transmissions thiab zog. Yog li ntawd, nyob ntawm seb qhov kev siv qhov chaw, xws li cov kis tau tus mob, thiab lwm yam tsis raug txiav txim los ntawm cov yam ntxwv ntawm cov iav roj.
Zoo cov khoom yuav tsum muaj cov nram no ua ke nrog ntawm cov yam ntxwv:
- Cov roj nplua nyeem yuav tsum tau muaj ib tug kub siab thiab antiwear zog.
- Tsis tas li ntawd cov khoom muaj siab viscosity yam ntxwv ntawm tag nrho cov muaj peevxwm. Qhov no saib kuas high-zoo lubrication thaum CPR yog tsim nyog los ua hauj lwm rau tus mob khaub thuas. Cov yam ntxwv ua rau nws tau los xyuas kom meej qhov kev kawm theem ntawm cov khoom viscosity.
- Roj rau transmissions yuav tsum tau muaj ib tug uas tsis muaj theem ntawm xeb Aggressiveness. Qhov no yog ib qho tseem ceeb rau hauv qhov chaw ua los ntawm uas tsis yog-ferrous hlau.
- Tshwj xeeb cov yam ntxwv - nws yog stability thaum lub sij hawm thermal oxidation. Qhov no saib kuas ib qhov theem ntawm viscosity.
- Ib qho tseem ceeb parameter - lub siab tshaj plaws qib ntawm kev tiv thaiv tiv thaiv xeb thiab tsawg heev rau lub sealing cov ntaub ntawv uas.
Classification los ntawm API
Hom iav roj thiab lawv cov yam ntxwv kuj txwv kom muab zais raws li API system. Nws yog tsi ntawm Lavxias teb sab qhua. Tiam sis ntawm no nws yog muab tshem mus rau hauv tus account tsis tau tsuas yog cov viscosity, tab sis kuj cov nruab nrab uas yog haum rau ib tug los yog lwm lubricant:
- API GL-1 - yog ib tug yooj yim mineral hauv paus, nyob rau hauv uas muaj pes tsawg leeg tsis muaj additives. Nws yog tsim los siv nyob rau hauv tsis muaj-load o thiab mob ntsws tej yam kev mob. конусной и червячной. Cov lubricants yuav siv tau nyob rau hauv cov khoom bessinhronizatornyh txhua yam gearshift, thiab nyob rau hauv lub zog - thiab lub cab Taper.
- GL-2 - yog ib tug mineral luj roj thiab additives, tiv thaiv tiv thaiv galling. Qhov no tiv thaiv yog heev zoo thaum nws yog siv nyob rau hauv mechanisms nrog ib tug nruab nrab load theem. Cov lubricants cov kev ua tsaws thauj thiab ua liaj ua teb cov cuab yeej.
- GL-3 tsuas yog puag roj muaj kuj additives rau coj kev tiv thaiv. Lawv tus xov tooj yog 2.7% ntawm tag nrho cov muaj pes tsawg leeg. Cov hom iav roj yog pom zoo rau nruab nrab-duty cov tsheb thauj khoom nyob rau hauv lub conical zog. Tsis txhob siv cov khoom nyob rau hauv Hypoid zog
- GL-4 - universal roj npaj rau tej load. Raws li ib feem ntawm lub hauv paus muaj ib tug mineral hauv paus thiab EP additives nyob rau hauv ib tug npaum li ntawm 4%. Cov lubricants yog lug siv nyob rau hauv tsav axles, nyob rau hauv PPC tshuab tsis synchronizers. Thawv rau synchronized iav haum lub hom iav roj, thiab lawv daim ntawv thov yuav ua kom cov chaw ua hauj lwm ntau npaum thawv. Raws li ib feem ntawm cov roj nplua nyeem muaj ntau tshaj li 50% sib txawv kev tiv thaiv additives.
- GL-5 - yog tshwj xeeb cov khoom tsim los khiav lag luam nyob rau hauv tej yam kev mob ntawm siab load transmissions. Muaj yog ib tug 6.5% additives enhanced zog. Nws yog ib tug universal kis tau tus mob roj. Specifications nws zoo tagnrho rau cov hnyav luag hauj lwm yam. Tab sis cov khoom yog tsis haum rau tej CIO.
xaus
. Yog li, peb soj ntsuam lub hom iav roj thiab lawv cov yam ntxwv. Raws li koj tau pom, muaj ib tug ncaj sab kev faib ntawm lubricating cov khoom. Thaum xaiv txoj cai iav roj yog ib qho tseem ceeb mus nrhiav tsis tau tsuas yog rau nws chav kawm ntawv thiab lub dag lub zog, tab sis kuj mus rau lub tswv yim pom zoo ntawm lub chaw tsim tshuaj paus.
