Lubricants yog hu ua cov ntaub ntawv ntawm ntau yam tshwj xeeb siv los txo kev hnav ntawm ntau yam ntawm cov nodes thaum muaj kev sib txhuam ntawm lawv cov qauv. Cov khoom ntawm hom no tuaj yeem sib txawv hauv qhov sib xws. Cov yam ntxwv ua tau zoo ntawm cov cuab yeej zoo li no thiab qhov kev siv ntawm lawv yog nyob ntawm qhov ntsuas no. Feem ntau hauv kev lag luam, nrog rau cov khoom siv hauv tsheb, piv txwv li, NLGI 2 roj siv.

Kev faib tawm thiab cov chaw tsim khoom

NLGI yog qhov kev faib roj roj thoob ntiaj teb tsim los ntawm American non-profit lub koom haum National Lubricating Grease Institute. Lub tuam txhab no tau tsim nyob rau hauv Teb Chaws Asmeskas rov qab rau hauv 30s ntawm lub xyoo pua xeem. Tam sim no, nws suav nrog ntau yam kev tshawb fawb, kev cob qhia, cov koom haum pabcuam.

NLGI 2 cov roj tau muag niaj hnub no, suav nrog cov tuam txhab muaj npe nrov. Piv txwv li, yog tias koj xav tau, hauv peb lub sijhawm koj tuaj yeem yuav cov khoom lag luam hauv qab no:

• Delo.
• Shell.

Thawj qhov ntsuas tau ua los ntawm National Lubricating Grease Institute yog qhov sib xws lossis qhov ntom ntawm cov roj. Txhawm rau kuaj cov ntaub ntawv zoo li no hauv lub chaw soj nstuam ntawm lub koom haum no, cov txheej txheem ntawm kev ua haujlwm nkag mus yog siv. Qhov ntom ntawm cov khoom raug kuaj xyuas los ntawm lub koom haum cov kws tshaj lij uas siv cov cuab yeej tshwj xeeb - penetrometer nrog lub khob hliav qab. Cov cuab yeej no tau txo qis rau 5 vib nas this rau hauv cov roj rhuab mus rau 25 ° C. Tom ntej no, ntsuas qhov tob ntawm lub khob hliav qab.

siv thaj chaw

Greases ntawm NLGI chav kawm los ntawm 000 txog 6 tuaj yeem muag hauv khw niaj hnub no. Cov ntaub ntawv ua kua ntau ntawm cov khoom siv no yog siv rau hauv cov tshuab nrog me me hla ntu ntawm cov khoom siv. Cov khoom siv roj nplua nyeem tuaj yeem siv tau, piv txwv li, rau qhib iav.

NLGI 2 cov ntaub ntawv hauv chav kawm tuaj yeem siv ntau yam ntawm cov khoom thiab cov txheej txheem. Tam sim no, chav kawm ntawm cov roj no yog qhov nrov tshaj plaws thiab nthuav dav. Feem ntau, cov khoom siv no yog siv rau hauv bearings rau tsheb thiab tsheb thauj khoom.

Kev sib xyaw thiab ntau npaum li cas

Cov khoom ntawm ntau yam no feem ntau yog ua los ntawm ISOSIN ™ cov roj hauv paus. Lawv kuj tseem muaj cov khoom xyaw hauv qab no:

• tacky thiab siab siab ntxiv.

Cov xim ntawm cov ntaub ntawv hauv chav kawm no, nyob ntawm hom, tej zaum yuav yog xim av, daj lossis xiav.

Tau kawg, siv cov roj no hauv cov txheej txheemyuav tsum txaus kom txo tau qhov kev sib txhuam quab yuam. Qhov ntau npaum li cas ntawm NLGI 2 roj nyob ntawm seb qhov tshwj xeeb uas lawv tau siv. Thaum siv cov nyiaj no rau qhov no, ib qho yuav tsum tau coj los ua ntej, los ntawm phau ntawv hla tebchaws thiab cov lus pom zoo los ntawm cov chaw tsim khoom ntawm cov cuab yeej tshwj xeeb no.

Cov roj ntawm hom no yog tsim los ntawm cov ntawv luv NLGI - los ntawm lub npe National Lubricating Grease Institute. Tom qab cov ntawv hauv qhov cim, tus lej 2 tau muab tso rau - ib chav kawm tshwj xeeb ntawm cov khoom.

Quality requirements

Piv rau cov roj lubricating ib txwm, NLGI lubricating roj muaj lub neej ua haujlwm ntev dua hauv ntau lub rooj sib txoos thiab cov txheej txheem. Tau kawg, cov neeg tsim khoom koom nrog hauv kev tsim cov khoom siv no yuav tsum ua raws li qee qhov kev cai thaum lawv tso tawm. Txwv tsis pub, chav kawm khoom tiav yuav tsum tsis raug muab. Ntawm qhov hluav taws xob, cov roj nplua nyeem yuav tsum ua raws li NLGI cov qauv.

NLGI 2 cov ntaub ntawv yuav tsum txaus siab rau cov khoom thiab cov txheej txheem, suav nrog qhov kub thiab txias. Cov kev xav tau siab kuj tau muab tso rau ntawm lawv cov kav ntev, qib ntawm evaporation, oxidation, hloov hauv viscosity. Txhawm rau tiv thaiv cov bearings thiab lwm yam khoom siv los ntawm corrosion thiab hnav, cov khoom zoo li no yuav tsum ua kom zoo li sai tau.

Delo NLGI 2 Khoom Specifications

Greases ntawm hom no yog tsim los ntawm American corporation Chevron, ib tug ntawm cov loj tshaj plaws nyob rau hauv lub ntiaj teb no.
