Cov twj tua hluav taws yog cov khoom tseem ceeb ntawm kev tiv thaiv hluav taws, thiab xaiv hom kev ncaj qha cuam tshuam rau cov lus teb thaum muaj xwm txheej ceev thiab kev nyab xeeb. Kev nkag siab txog cov kev faib tawm tseem ceeb thiab lawv qhov xwm txheej- cov txiaj ntsig tshwj xeeb yog qhov tseem ceeb rau kev txiav txim siab paub.
Ua ntej,los ntawm hom tsav, cov twj tua hluav taws tau muab faib ua hluav taws xob thiab diesel- tsav cov qauv. Cov twj hluav taws xob hluav taws xob cia siab rau lub zog hluav taws xob, muab kev ua haujlwm ruaj khov, tsis tshua muaj suab nrov, thiab kev saib xyuas yooj yim - zoo tagnrho rau cov chaw lag luam, siab - qhov chaw nyob, thiab cov tsev kho mob uas muaj hluav taws xob zoo. Diesel-tsiv cov twj tua hluav taws, txawm li cas los xij, muaj cov khoom siv hluav taws xob ywj pheej, ua kom muaj kev ua kom muaj zog txawm tias thaum muaj hluav taws xob, ua rau lawv qhov tseem ceeb rau cov chaw lag luam nyob deb nroog, cov tsev nyob deb nroog, lossis thaj chaw uas muaj hluav taws xob.
Thib ob,los ntawm tus qauv, ob pawg tseem ceeb yog centrifugal thiab cov twj tso kua mis zoo. Cov twj tua hluav taws centrifugal yog cov siv dav tshaj plaws, siv zog sib hloov los ua kom muaj kev kub ntxhov thiab cov nqi ntws loj. Lawv zoo meej rau cov tsev siab - nce siab, cov khw muag khoom, thiab cov chaw tsim khoom loj uas xav tau kev xa dej ntev ntev los yog lub taub hau siab (dej siab). Cov twj tso kua mis zoo, suav nrog cov piston thiab hom iav, xa cov dej ntws zoo ib yam tsis hais txog kev hloov pauv, haum rau cov xwm txheej me me xws li cov chaw nres tsheb hauv av, cov tsev khaws khoom me me, lossis cov chaw uas muaj dej tsis txaus tab sis cov kev xav tau ruaj khov.
Tsis tas li ntawd, cov hom tshwj xeeb haum rau cov kev xav tau tshwj xeeb:tawg- pov thawj cov twj tua hluav taws(nrog rau lub cev muaj zog thiab corrosion-cov ntaub ntawv tiv taus) yog qhov yuav tsum tau ua rau cov nroj tsuag tshuaj, cov roj refineries, thiab lwm qhov chaw kub hnyiab;submersible hluav taws twj tso kua misyog tsim rau underwater installation, zoo tagnrho rau hauv qab daus los yog tej thaj chaw uas muaj dej nyab; thiablow- suab nrov hluav taws twj(nruab nrog lub suab rwb thaiv tsev thiab kev co- cov khoom damping) haum lub suab nrov- qhov chaw rhiab heev xws li tsev kho mob, tsev so, thiab cov tsev nyob.
Txhawm rau xaiv qhov zoo, ua qhov tseem ceeb rau peb yam: koj lub vev xaib lub zog muaj kev ntseeg siab (txiav txim siab hluav taws xob vs. diesel), dej xav tau (ntev tus nqi thiab lub taub hau yuav tsum), thiab ib puag ncig (xws li, flammability, suab nrov txwv). Sib piv cov twj tso kua mis rau cov kev xav tau no ua kom pom kev ua haujlwm zoo thaum muaj xwm txheej kub ntxhov.
