Cov ntsaws ruaj ruaj yog cov khoom siv tseem ceeb hauv cov khoom siv hauv kev lag luam uas tiv thaiv cov dej xau, roj av, thiab lwm yam kev tshaj tawm ua haujlwm thaum thaiv kev nkag mus ntawm cov kab mob sab nraud xws li plua plav thiab impurities. Txawm hais tias me me, cov ntsaws ruaj ruaj ncaj qha cuam tshuam cov cuab yeej ruaj khov, kev pabcuam lub neej, thiab cov nqi tu; Lawv tau dav siv thoob plaws cov haujlwm suav nrog kev tsim khoom siv tshuab, petrochemicals, tsheb, siv tshuab, hluav taws xob, thiab khoom siv hauv tsev.
Raws li lawv cov kev khiav hauj lwm hom thiab installation qhov chaw, cov ntsaws ruaj ruaj muaj categorized rau zoo li qub seals thiab dynamic seals. Cov ntsaws ruaj ruaj feem ntau yog siv rau ntawm cov ntsiab lus txuas ruaj khov-xws li flanges, yeeb nkab fittings, thiab valve lub cev- nrog cov piv txwv xws li O-rings thiab roj hmab gaskets. Dynamic ntsaws ruaj ruaj yog ua hauj lwm nyob rau hauv cov cheeb tsam uas muaj cov txheeb ze zog, xws li hydraulic thooj voos kheej kheej, rotating ncej, thiab pistons; Cov khoom siv xws li roj foob, hydraulic foob, thiab plua plav wipers.
Muaj ntau yam khoom siv los tsim cov khoom lag luam, suav nrog cov roj hmab nitrile (NBR), ethylene propylene diene monomer (EPDM) roj hmab, fluoroelastomers (FKM), silicone roj hmab, polyurethane, thiab polytetrafluoroethylene (PTFE). Txij li cov khoom sib txawv muaj ntau theem ntawm kev tiv thaiv rau roj, dej, kub kub, hnav, thiab corrosion, kev xaiv ntawm cov khoom siv thiab tsim yuav tsum tau ua raws li cov khoom siv tshwj xeeb kev khiav hauj lwm siab, kub, nruab nrab, thiab hom kev txav.
Raws li cov khoom siv hauv kev lag luam hloov mus rau kev ua tau zoo dua, kev ua haujlwm siab dua, thiab kev pab cuam lub neej ntev, kev ua tau zoo ntawm cov ntsaws ruaj ruaj tau dhau los ua nruj dua. Cov ntsaws ruaj ruaj niaj hnub no yuav tsum tsis tsuas yog muab kev sib khi zoo xwb tab sis kuj tseem muaj kev hnav zoo heev, tiv thaiv kev laus, thiab kev hloov pauv ib puag ncig. Los ntawm kev nce qib hauv cov ntaub ntawv, kev tsim kho kom zoo, thiab txhim kho cov txheej txheem tsim khoom, cov ntsaws ruaj ruaj tau hloov mus rau kev ua haujlwm siab, kev ua tau zoo, thiab ua haujlwm ntev, yog li ua kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm ntau hom khoom siv.
