Roj: SAIB 20 thiab variants. Roj viscosity yog ntsuas ntawm 210 degrees F, uas yog qhov kev khiav hauj lwm kub ntawm lub combustion engine sab hauv. Cov SAIB 20 yog tib yam viscosity li 5W- 20 lub cev muaj zog roj ntawm 210 degrees.
Ib sab ntawm no, SAE 20 roj siv rau dab tsi?
3-IN-IB® Tsav Roj yog a SAIB 20 kev sib xyaw tshwj xeeb ntawm qib siab cov roj engineered rau 1/4 HP motors los yog loj dua. Cov mis no ntev ntev yog zoo li lub tshuab hluav taws xob roj thiab lubricant, thiab tuaj yeem ua tau siv rau tuav cov tshuab xaws tshuab, xyaum, cov cuab yeej nyom, thiab lwm yam.
Ib yam li ntawd, SAE qib yog dab tsi? SAE viscosity Qib rau Cav Roj Lub Koom Haum ntawm Automotive Engineers ( SAE ) viscosity grading system rau cov roj cav muaj "W" qib uas txhais tau tias tsis tshua muaj viscosities thiab "ncaj" qib uas muab kev txwv ntxiv rau qhov kub siab viscosities.
Xav txog qhov no, qhov sib npaug ntawm SAE 20 roj li cas?
SAE 10 W yog sib npaug rau ISO 32, SAIB 20 yog sib npaug rau ISO 46 thiab 68, thiab SAE 30 yog sib npaug rau ISO 100.
SAE roj sawv rau dab tsi?
SAE sawv rau "Society of Automotive Engineering" thiab qhov no lawv tuaj nrog cov txheej txheem ci ntsa iab rau qib lub cev muaj zog cov roj Raws li lawv viscosity. Viscosity yog ntsuas los ntawm qhov ntev npaum li cas nws yuav siv sij hawm ib tug npaum li cas ntawm roj ntws los ntawm ib lub thawv ntawm qhov kub thiab txias. Piv txwv li: SAE 10W-30, SAE 10W-40 los yog SAE 30.

Dab tsi yog bureaucracy thiab nws cov haujlwm yog dab tsi?
Cov haujlwm ntawm Tsoom Fwv Teb Chaws Bureaucracy. Tsoom fwv teb chaws bureaucracy ua peb lub luag haujlwm tseem ceeb hauv tsoomfwv: kev siv, kev tswj hwm, thiab kev tswj hwm. Kev ua haujlwm niaj hnub ntawm bureaucracy - sau nqi, muab ntawv tso cai, muab xeem, thiab ntxiv rau - yog kev tswj hwm ntawm nws lub hom phiaj
Dab tsi yog rau lub tshuab yooj yim thiab cov piv txwv ntawm lawv yog dab tsi?
Cov no yog rau lub tshuab yooj yim: cov nplais, lub log thiab lub qag, qib, lub dav hlau inclined, ntsia hlau, thiab lub log
Dab tsi yog qhov sib npaug rau SAE 30 roj?
SAE 10W30 yog cov roj uas muaj SAE 10W viscosity (thickness) ntawm qhov kub thiab txias, thiab SAE 30 viscosity ntawm qhov kub thiab txias. W stands rau 'Lub caij ntuj no'. Nco ntsoov tias cov viscosities no yog cov txheeb ze, thiab cov lej qauv thiab tsis muaj qhov tseeb, cov roj tsis tau thicker thaum nws kub, nws tau thinner
Kev tswj hwm kev paub yog dab tsi nws lub hom phiaj yog dab tsi?
Lub hom phiaj ntawm kev tswj hwm kev paub yog muab cov ntaub ntawv txhim khu kev qha thiab ruaj ntseg, nrog rau ua kom muaj thoob plaws hauv koj lub koom haum lub neej. Muaj peb lub hom phiaj tseem ceeb ntawm KM thiab lawv yog: Ua kom lub koom haum ua haujlwm zoo dua. Xyuas kom txhua tus neeg ua haujlwm muaj kev nkag siab meej thiab sib koom ua ke
CAM cov nroj tsuag yog dab tsi thiab lawv qhov zoo dua yog dab tsi?
Crassulacean Acid Metabolism (CAM) muaj qhov zoo ntawm qhov tseem ceeb tshem tawm evapotranspiration los ntawm cov nroj tsuag stomata (dej poob los ntawm kev sib pauv roj) thaum nruab hnub, tso cai rau CAM cov nroj tsuag kom muaj sia nyob hauv cov huab cua tsis zoo uas dej poob yog qhov tseem ceeb txwv rau kev loj hlob ntawm cov nroj tsuag
