Cov cua compressed tso tawm los ntawm lub tshuab nqus tsev twj thiab cua compressors yuav tsum tau ua kom tshem tawm impurities, ya raws, thiab roj paug, yog li ua tau raws li qhov kev ua haujlwm tshwj xeeb ntawm ntau yam kev lag luam. Cov kauj ruam ua haujlwm feem ntau suav nrog kev pom, ziab, thiab tshem tawm roj.
Ua ntej, filtration yog lub hauv paus kauj ruam. Cov huab cua compressed ua ntej dhau los ntawm pre- lim (nrog qhov tseeb ntawm 5-10 μm) kom tshem tawm cov teeb meem loj heev - xws li plua plav thiab xeb - thiab lwm yam impurities, yog li tiv thaiv kev puas tsuaj rau cov khoom siv hauv qab. Tom qab ntawd nws pib los ntawm kev lim dej (nrog rau qhov tseeb ntawm 0.1-1 μm) kom lim tawm cov impurities zoo dua thiab ua kom huab cua purity. Kev lag luam xws li khoom noj khoom haus thiab kev tsim kho mob, uas yuav tsum tau muaj ib puag ncig tsis muaj menyuam, yuav tsum siv ultra{10}}cov lim dej (nrog qhov tseeb ntawm 0.01 μm) kom ua tau raws li cov qauv aseptic nruj.
Qhov thib ob, ziab yog ua haujlwm kom tshem tawm cov dej noo. Raws li compressed cua txias, nws generates condensate; Cov dej noo no yuav tsum tau muab tshem tawm nrog lub tshuab ziab khaub ncaws. Adsorption tshuab ziab khaub ncaws tuaj yeem txo cov huab cua cov lwg taw rau hauv qab -40 degree, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom qhuav (xws li, kev tsim hluav taws xob thiab pneumatic instrumentation). Cov tshuab ziab khaub ncaws txias feem ntau ua tiav qhov dej lwg ntawm 2-10 degree; cov no yog tsim rau kev siv dav dav, muaj peev xwm ua tau raws li cov kev xav tau ntawm cov cuab yeej pneumatic feem ntau thaum txo qhov corrosion thiab txhaws ntawm cov kav dej thiab cov khoom siv los ntawm cov dej noo.
Thaum kawg, kev tshem tawm roj yog cov txheej txheem tshwj xeeb tsim rau cov roj-lubricated cua compressors. This is achieved using oil-removal filters (such as activated carbon filters) to adsorb oil contaminants from the air, thereby reducing the residual oil content to below 0.01 mg/m³. Txawm hais tias cov roj- cov cua compressors dawb tsis tas yuav tshem tawm cov roj, lawv cov pa tawm yuav tsum tau saib xyuas ib ntus rau cov ntsiab lus roj kom ua raws li cov qauv kev ua haujlwm. Cov txheej txheem compressed cua yog tom qab ntawd coj mus rau hauv lub tshuab txais huab cua kom ruaj khov thiab txo qis kev hloov pauv, thaum tseem ua kom yooj yim rau kev sib cais ntxiv ntawm qhov seem condensate. Cov cua txais lub tank yuav tsum tau drained ib ntus kom tiv thaiv kom tsis txhob ya raws. Cov kev xav tau ntawm kev ua haujlwm sib txawv hauv kev lag luam; Piv txwv li, cov khoom noj khoom haus thiab kev kho mob yuav tsum ua raws li cov qauv kev tu cev nruj, thaum kev lag luam hluav taws xob xav tau qib siab purity thiab qis qis. Yog li ntawd, cov cuab yeej kho cua yuav tsum tau teeb tsa raws li cov kev xav tau tshwj xeeb los xyuas kom meej tias cov cua compressed zoo tsis tu ncua raws li cov qauv xav tau.
