1. Taw qhia: Vim li cas Micron Ratings tseem ceeb dua li koj xav
Nyob rau hauv niaj hnub kev lag luam pom, kev ua tau zoo yog feem ntau ntsuas tsis tau tsuas yog los ntawm kev ua kom huv si, tab sis kuj los ntawm kev ua haujlwm zoo npaum li cas hauv lub sijhawm. Ntawm tag nrho cov kev specifications, lubmicron ntsuam xyuas ntawm lub hnab limsawv tawm raws li ib tug ntawm cov feem ntau influential. Nws cuam tshuam ncaj qhafiltrate zoo, siab poob, lim lifespan, cov nqi khiav lag luam, thiab cov khoom siv tiv thaiv.
Txawm li cas los xij, ntau tus kws tshaj lij thiab cov kws tshaj lij kev muag khoom tseem kho qhov ntsuas micron raws li tus lej yooj yim ntawm daim ntawv teev cov ntaub ntawv, tsis yog qhov sib txawv ntawm qhov kev ua tau zoo uas yuav tsum tau ua kom haum rau cov yam ntxwv ntawm cov dej, cov txheej txheem xav tau, thiab qis qis.
Cov lus qhia no rhuav tshem qhov kev ntsuas micron tiag tiag sawv cev, lawv ntsuas li cas, thiab lawv cuam tshuam li cas kev coj cwj pwm hauv - ntiaj teb kev lag luam.
2. Dab tsi yog Micron hauv Cov Lus Pom Zoo?
A micron (µm)yog ib chav tsev ntawm qhov ntev sib npaug0.001 hlilos yogib -millionth ntawm ib 'meter'. Hauv kev pom, chav tsev no yog siv los piav txog qhovkwv yees qhov loj ntawm cov khoom sivtias lub hnab lim yog tsim los ntes.
Txhawm rau pom qhov scale:
|
Yam khoom |
Kwv yees qhov loj me (Micros) |
|

A 10-micron lim hnab, piv txwv li, yog tsim los tshem tawm cov khoom uas muaj kwv yees li 10 microns loj thiab loj dua, nyob ntawm nws cov kev faib tawm.
3. Qhov "Micron Rating" txhais li cas tiag?
Covmicron ntsuam xyuas ntawm lub hnab limyog ib qho qhia txog kev ua tau zoo uas piav txog qhovme me particle loj lub lim tawm tuaj yeem khaws ciaraws li cov kev xeem uas tau teev tseg.
Txawm li cas los xij, lo lus "ntseeg" yog qhov tseem ceeb. Tsis yog txhua qhov kev ntsuas micron txhais tau tias tib theem ntawm kev pom tseeb. Ob lub hnab uas sau tias "10 micron" yuav ua tau txawv heev nyob ntawm seb qhov ntsuas tau txhais thiab ntsuas li cas.
Qhov no ua rau ob hom kev ntsuas tseem ceeb tshaj plaws:
Nominal Micron Rating
Kev ntsuam xyuas Micron
4. Nominal vs. Kev Ntsuas Tsis Txaus Siab piav qhia
Nominal Micron Rating
Qhov ntsuas nominal qhia tias lub hnab lim yuav tshem tawmib feem pua ntawm cov khoom ntawm qhov loj me, feem ntau nruab nrab ntawm50% thiab 80%.
Qhov no txhais tau tias:
Qee qhov ntawm qhov ntsuas qhov loj tuaj yeem dhau mus
Kev ua tau zoo tuaj yeem sib txawv raws li tus nqi ntws thiab kua viscosity
Zoo tagnrho rau kev dav dav -lub hom phiaj thiab ua ntej- pom
Kev ntsuam xyuas Micron
Qhov ntsuas qhov tseeb qhia tau tias lub hnab lim yuav tshem tawmtsawg kawg yog 90% mus rau 99% ntawm cov khoomntawm qhov luaj li cas, feem ntau raug kuaj nyob rau hauv kev tswj chaw kuaj mob.
Qhov no txhais tau tias:
Ntau dua qhov sib xws
Kev tiv thaiv zoo dua rau cov khoom siv qis qis qis
Tus nqi siab dua thiab kev tswj xyuas nruj dua

5. Micron Ratings thiab Lim Kev Ua Haujlwm
Micron ntsuam xyuas cuam tshuam peb yam tseem ceeb ua haujlwm:
Particle Retention
Kev ntsuas qis dua micron ua rau muaj kev tshem tawm ntau dua rau cov kab mob zoo.
Siab poob
Raws li micron kev ntsuas txo qis, kev tiv thaiv kom ntws nce, ua rau muaj kev sib txawv siab dua thoob plaws lub lim.
Dirt-Tuav muaj peev xwm
Cov lim dej coarser feem ntau tuav cov kab mob ntau dua ua ntej yuav tsum tau hloov pauv, thaum cov lim lim lim lim tau nrawm dua.
