Hlau nqaj qhov ntev rau W30X90 seem
Lub ntsiab lus ntawm W30 × $ hoov qauv
W: Sawv rau dav-flange H-puab cov qauv hlau (cov duab flange yog qhov zoo sib xws), thiab cov ntoo khaub ncaws liab qab yog sib npaug.
30: Tus ntoo khaub lig-ntu qhov siab yog txog 30 ntiv tes (762 hli) (qhov tseeb me me yuav txawv me ntsis vim muaj cov txheej txheem ntau lawm).
90: Qhov hnyav theoretical ib txhais ko taw ntev yog hais txog 90 phaus (txog 134.1 kg \/ m).

Cov Cuab Yeej Siv Cov Neeg Kho Tshuab thiab Qhov Zoo ntawm W30X90 Dav Flange Beab
1. Ntu Cwj Pwm
Lub zog bender tsis kam: cov flange flange tsim ua ntu ntu Inertia lub sijhawm (SAB, SY) thiab tuaj yeem tiv thaiv ntau dua los ntawm ntau dua los yog khoov ntau dua los yog
Siab ruaj khov: puab qhov chaw sab hauv thiab sab nraud ntawm flange yog kev sib txuas, uas yooj yim rau kev sib txuas (xws li stability zoo dua li ntawm nqaim flange steel.
2. Kev Lag Luam
Piv nrog tsoos kuv-nqaj, w30 × 90 tau txuag 10% -30% ntawm cov ntaub ntawv ntawm tib lub cev hnyav, thaum txo cov kev tsim kho (xws li vuam thiab bolting); Nws yog qhov haum rau cov qauv loj, txo cov ntsiab lus txhawb nqa, thiab ua kom zoo rau tag nrho cov nqi.

1. Kev tsim kho txhim kho tshuab
Kev nce qib tsev: raws li lub nqaj hlau thiab kem, nws bears ntsug loads thiab tshuab kab rov tav loads \/ Seismic thauj khoom.
Muaj Nroj Tsuag: Siv rau cov npoo av loj loj thiab crane nqaj kom tau raws li cov khoom yuav tsum muaj cov khoom siv hnyav.
2. Choj engineering
Txoj kev loj \/ Railway choj txuas hniav: raws li lub ntsiab nqaj lossis Pier qauv, nws Dynamic dynamic thiab hloov kev ntxhov siab.
Tag nrho cov choj nqaj choj: ua ke nrog cov pob zeb ua pob zeb ua cov sib xyaw ua ke txhawm rau txhim kho kev txhav txhav txhav txhav txhav txhav txhav txhav.
3. Cov Machinery thiab khoom siv
Cov khoom siv hnyav MACHINERY: xws li cov qauv txhawb nqa ntawm cranes thiab cov khoom siv mining.
Cov Khoom Siv Hauv Lub Hauv Paus: siv rau lub hauv paus ntawm cov tshuab loj los muab kev txhawb nqa ruaj khov.
4. Lwm liaj teb
Marine Engineering: xws li ntug dej hiav txwv platform (yuav tsum koom tes nrog kev kho mob corrosion).
Cia racking: kab thiab kab teeb rau cov tshuab hluav taws xob siab.
