Ntawm txhua yam ntawm cov lim dej, cov khoom lim dej yog cov khoom tseem ceeb kom ua tiav cov haujlwm lim dej. Nws zoo li "kev tiv thaiv kab mob ua pa" ntawm cov khoom siv. Nws cais cov impurities thiab cov kuab paug hauv cov kua (gas lossis kua) los ntawm kev cuam tshuam lub cev, adsorption thiab lwm txoj hauv kev los xyuas kom meej tias qhov nruab nrab nkag mus rau hauv cov dej ntws tau raws li tus qauv kev huv, yog li tiv thaiv kev nyab xeeb thiab ruaj khov ntawm cov khoom siv. cov

Lub luag haujlwm tseem ceeb ntawm cov khoom lim yog qhov pom tseeb. Txawm hais tias nws yog lub tshuab lim cua hauv huab cua lim, lossis cov khoom siv lim hauv cov roj lim thiab roj lim, nws yuav tsum xaiv qhov tsim nyog pom tseeb raws li qhov yuav tsum tau ua. Piv txwv li, lub tshuab lim cua yuav tsum lim cov plua plav, xuab zeb thiab lwm yam khoom hauv huab cua kom tsis txhob nkag mus rau hauv lub tog raj kheej lub cav thiab ua rau hnav; cov roj lim cov ntsiab lus yuav tsum tau cuam tshuam cov impurities xws li sludge thiab hlau khib nyiab tsim nyob rau hauv cov roj ncig kom tiv thaiv cov cav tseem ceeb ntawm kev puas tsuaj vim lubrication tsis zoo. cov
Los ntawm cov qauv kev pom, cov khoom lim feem ntau yog tsim los ntawm cov khoom siv lim dej, cov ncej txhawb nqa thiab lub foob. Cov khoom siv lim yog "lub siab" ntawm cov khoom lim. Cov ntaub ntawv muaj xws li cov ntawv lim, tsis yog- woven fabrics, hlau mesh, activated carbon, thiab lwm yam. Cov ntaub ntawv sib txawv muaj txawv filtering kev ua tau zoo: lim ntawv thiab tsis yog -woven fabrics yog haum rau intercepting khoom hais, thaum activated carbon yog zoo ntawm absorbing tsw, organic pollutants, thiab lwm yam.; kev txhawb nqa ncej plays lub luag haujlwm ntawm kev kho cov khoom lim kom paub meej tias cov khoom lim tsis deform nyob rau hauv cov dej siab; lub foob kom paub meej tias tag nrho cov kua dej yog lim los ntawm cov khoom siv lim kom tsis txhob muaj qhov nruab nrab tsis muaj dej ntws ncaj qha. cov
Nyob ntawm daim ntawv thov scenario, cov khoom lim tuaj yeem muab faib ua ntau hom. Ntxiv nrog rau cov ntsiab lus huab cua lim, kuj tseem muaj cov roj lim roj, roj lim cov ntsiab lus, hydraulic roj lim cov ntsiab lus, cov dej lim dej, thiab lwm yam. Txhua lub lim dej yog tsim los rau kev tshaj tawm thiab kev lim dej. Piv txwv li, cov roj lim cov khoom yuav tsum muaj cov yam ntxwv ntawm cov roj corrosion kuj thiab siab filtering efficiency los tiv thaiv cov roj txhaj tshuaj system; cov hydraulic roj lim caij muaj qhov siab lim dej kom raug kom tsis txhob muaj qhov tsis ua haujlwm ntawm cov khoom siv hydraulic vim impurity clogging. cov
Thaum siv, kev saib xyuas thiab hloov cov lim dej yog qhov tseem ceeb heev. Raws li lub sijhawm lim dej nce ntxiv, cov khoom siv lim yuav maj mam txhaws los ntawm impurities, uas ua rau txo qis hauv kev lim dej thiab qhov nce hauv qhov tsis kam, cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas cov xwm txheej ntawm lub lim dej raws li qhov xav tau ntawm cov khoom siv phau ntawv. Thaum lub siab txawv txav, txo qis, thiab lwm yam tshwm sim, cov khoom lim yuav tsum tau hloov nyob rau lub sijhawm kom ntseeg tau tias cov lim ib txwm ua lub luag haujlwm zoo lim dej thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv.
