Thaum lub sij hawm tunneling txheej txheem ntawm ib tug shielding tshuab, lub taub hau cutter yuav tsum tau ib tug tas mus li khoom ntawm ntau yam xov xwm -xws li slurry, ua npuas ncauj, hydraulic roj, thiab sealing roj- kom tswj tau cov dej ntws, txias, lubrication, thiab sealing functions. Muab hais tias lub taub hau cutter tau tig mus tas li los ntawm 360 degrees, yuav ua li cas cov xov xwm sib txawv no tuaj yeem tso siab tau los ntawm qhov chaw nres tsheb mus rau qhov kawg tig? Cov lus teb yog nyob rau hauv qhov loj -bore, multi-passage rotary joint.
I. Kev Pom Zoo Ntawm Tus Qauv: Cov Txheej Txheem Kev Sib Txuas Tseem Ceeb Tom Qab Cutter Lub Taub Hau
Qhov norotary sib koomfeem ntau yog ntsia rau ntawm qhov chaw los yog tom qab ntawm lub ntsiab tsav gearbox; nws rotating seem yog rigidly txuas mus rau lub cutter taub hau tsav flange. Raws li lub taub hau cutter tig, cov kev ywj pheej sab hauv hauv kev sib koom ua ke tig synchronously, xa cov xov xwm sib txawv sib txawv yam tsis muaj kev sib kis - paug lossis xau. Tus naj npawb ntawm cov nqe lus tuaj yeem hloov kho kom tau raws li qhov tshwj xeeb ua haujlwm ntawm lub tshuab tiv thaiv, nrog rau 6 txog 12 nqe lus yog qhov kev teeb tsa ntau tshaj plaws.
II. Loj Bore: Ua Ntej Flow Rate Tshaj "Speed"
Rau cov tshuab loj- teev cov ntaub thaiv npog (piv txwv li, cov kab uas muaj qhov ntev tshaj 12 meters), qhov ntim ntawm cov xov xwm xav tau rau kev txiav lub taub hau thiab txias yog qhov tseem ceeb. Lub hom phiaj tseem ceeb ntawm qhov loj -ntev tsim- qhov twg lub hauv paus bore txoj kab uas hla tuaj yeem ncav cuag DN300 lossis loj dua - yog kom txo qis kev khiav hauj lwm thiab xyuas kom muaj qhov txaus txaus. Qhov no tau lees tias slurry thiab ua npuas ncauj xa tuaj sai sai rau lub taub hau txiav lub ntsej muag, yog li tiv thaiv kev tsim cov av nkos thiab averting cutter overheating.
III. Multi-Segment Design: Tsav los ntawm Engineering Constraints, Enabling Maintenance Convenience
Rotary pob qij txha siv nyob rau hauv cov ntaub thaiv npog cov cav tov feature ib tug elongated profile (mus txog qhov ntev ntawm 3 mus rau 5 meters); Yog li ntawd, ib qho -daim, monolithic qauv nthuav tawm cov kev sib tw ntawm cov khoom siv machining kev txwv kev mus los thiab kev txwv loj thauj mus los. Yog li, engineering xyaum tau dav siv ntau yam - ntu, kev tsim qauv qauv: tag nrho cov kev sib dhos tau muab faib ua ob peb ntu, txhua lub tsev nyob hauv cov khoom sib khi thiab cov kabmob txhawb nqa. Cov ntu no tom qab ntawd tau koom ua ke siv qhov tseeb spigot-thiab-recess locating mechanisms thiab flange connections.
Cov txiaj ntsig tseem ceeb uas tau pom los ntawm qhov kev tsim no suav nrog:
- Feasibility nyob rau hauv Machining thiab Thauj: Qhov ntev ntawm txhua ntu yog khaws cia nyob rau hauv cov kev txwv ntawm kev ua hauj lwm ntawm cov txheej txheem tshuab cuab yeej thiab cov pa loj thauj mus los.
- Ntawm -Site Serviceability: Nyob rau hauv qhov kev tshwm sim ntawm lub foob tsis ua hauj lwm los yog kev puas tsuaj nyob rau hauv ib tug tej ntu, tsuas yog ib feem yuav tsum tau dismantled thiab hloov; tsis tas yuav hoist thiab tshem tawm tag nrho cov kev sib koom ua ke sib dhos, yog li txo qis qis.
- Flexible Expandability: Thaum cov kev cai ua haujlwm yuav tsum tau nce lossis txo qis hauv cov nqe lus, qhov kev teeb tsa tuaj yeem hloov kho yooj yim los ntawm kev hloov kho qhov sib xyaw ua ke.

Kev sib koom ua ke ntawm cov loj-ntug, ntau- cov kab sib txuas sib txuas nrog ntau- ntu tsim yog ob qho tib si qhov tshwm sim ntawm kev nce qib thiab qhov nyuaj ntawm cov ntaub thaiv npog tunneling tshuab, thiab cov lus teb ua tiav los ntawm kev lag luam sib koom ua ke rau qhov kev xav tau ntawm kev ua haujlwm hnyav. Rau cov tuam txhab tsim khoom, kev nkag siab txog cov txheej txheem thev naus laus zis tom qab tsim qauv no muaj txiaj ntsig ntau dua li tsuas yog paub tias muaj cov khoom zoo li no.
