Raws li cov khoom siv tsis tau muaj nyob hauv kev lag luam niaj hnub thiab kev ua liaj ua teb, kev ua haujlwm thiab kev pabcuam lub neej nyob ntawm cov khoom tseem ceeb ntawm cov ntaub ntawv loj. Nkag siab cov khoom muaj feem tsuas yog pab cov neeg siv xaiv cov kev xav tau raws li kev xav tau zoo dua li nkag siab zoo dua lawv cov yam ntxwv ua haujlwm.
Cov khoom siv tseem ceeb ntawm cov twj muaj zog feem ntau suav nrog cov tsis muaj roj ntsha, cov ntaub ntawv xaiv ntawm cov khoom sib txawv cuam tshuam nrog lawv cov khoom lag luam corrosion, hnav tsis kam thiab tshuab zog. Lub cev lub cev, raws li lub plhaub sab nraud ntawm cov twj tso kua mis sab nraud, feem ntau yog ua los ntawm cov hlau cam khwb cia, hlau stainless lossis engineering plastics. Cam khwb cia hlau lub cev yog dav siv nyob rau hauv kev ua haujlwm dav dav vim lawv tus nqi qis thiab paub tab yog kev sib xyaw ua ke; Thaum lub sij hawm stainless hlau lub cev yog tsim nyog rau cov neeg muaj kev lag luam zoo xws li tshuaj lom neeg thiab dej hiav txwv desination. Nyob rau hauv xyoo tas los, engineering tshuab yas lub cev muaj kuj tau siv dav hauv kev tiv thaiv kev ua liaj ua teb thiab ib puag ncig kev tiv thaiv kev tiv thaiv thiab anti {4 4}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kev laus zog.
Raws li lub zog hluav taws xob tseem ceeb ntawm cov twj tso kua mis ntxig, cov khoom siv ntawm cov neeg tsis sib haum ncaj qha cuam tshuam cov kev ua tau zoo thiab ruaj khov ntawm lub twj tso kua mis. Cov khoom siv neeg yuam kev suav nrog cov hlau pov cam, tooj dag, hlau stainless thiab polymer compress. Feem ntau yog cov kav hlau nris yog tsim nyog rau cov neeg tsis huv huv cov dej huv, thaum bronze overnlers feem ntau siv nyob rau hauv high {- cavitation kev ua tau zoo; Cov hlau tsis muaj stainless hlau muaj cov yam ntxwv ntawm corrosion tsis kam thiab muaj zog siab, thiab haum rau kev ua haujlwm ua haujlwm nyuaj; Polymer sib xyaw ua ke yog cov kev tiv thaiv ib puag ncig ntawm kev tiv thaiv ib puag ncig thiab kev kho dej vim lawv cov hnav tsis kam thiab nrov nrov.
Raws li tus mob sib kis ntawm cov twj tso kua mis, tus ncej feem ntau yog ua los ntawm cov hlau tsis xeb lossis siab {{{main {{{{{icey steel kom paub tseeb tias nws qhov chaw ruaj khov thiab muaj zog thauj. Cov ntsaws ruaj ruaj yog feem ntau cov ntsaws ruaj ruaj lossis roj hmab ntsaws ruaj ruaj los tiv thaiv cov kua muag thiab txuas ntxiv kev pabcuam lub neej ntawm lub twj tso kua mis.
Hauv cov ntsiab lus, cov khoom xaiv ntawm cov twj muaj twj submersible yuav tsum ua kom muaj kev nkag siab zoo xws li ib puag ncig ua haujlwm, conveying nruab nrab thiab nqi. Nrog kev nce qib ntawm cov ntaub ntawv kev tshawb fawb, cov ntaub ntawv ntawm cov twj muaj twj submersible yuav muaj ntau yam sib txawv ntawm cov kev xav tau ntawm ntau yam kev lag luam. Nkag siab cov khoom siv no yuav pab cov neeg siv tau txais kev txiav txim siab ntau dua thaum yuav cov twj xa tawm.
