Tsim ntawm Vuam Seam ntawm Aluminium Alloy Siab -Speed ​​Nkoj

One of the most important goals in the manufacture of aluminum alloy high-speed ships is to achieve the design speed. In order to achieve the above goals, under the same hull line and the same main engine power, the lighter the weight of the empty ship means the faster the ship's speed, the lower the fuel consumption. The density of aluminum alloy is only 1/3 of that of steel, which can greatly Reduce the weight of the empty ship, this feature makes aluminum alloy very suitable as a material for building high-speed ships.

Ntxiv nrog rau kev tswj nruj ntawm qhov hnyav ntawm cov ntaub ntawv ntawm lub rooj tsavxwm thaum lub sijhawm tsim kho, kev siv vuam tsim ntawm aluminium alloy nkoj thiab kev siv cov vuam sib txuas ntau li ntau tau tuaj yeem tsis tsuas yog tswj vuam deformation, tab sis kuj txo qhov hnyav ntawm lub nkoj khoob. Txawm li cas los xij, vim tias kev sib txuas tsis txuas tsis haum rau kev ntxhov siab lossis qhov tshwj xeeb, peb yuav tsum tau ua tib zoo saib xyuas cov qauv hauv qab no:

Tsim cov kev cai rau welds nyob rau hauv siab -nkoj ceev specifications

1. Cov lus qhia tshwj xeeb yuav tsum muaj kev sib txuas welds ntawm ob -sided nruam vuam yog raws li hauv qab no: nruab nrab girder thiab ca keel, tshuab puag thiab txhawb cov qauv, roj- nruj thiab watertight qauv perimeter, tag nrho cov qauv ntawm lub kauj tsheb kauj vab, hauv qab thiab lub taub hau cov qauv hauv thaj tsam cuam tshuam, Kev txhawb nqa thiab qhov kawg ntawm stiffeners, ncej, cross braces thiab girders, saum lub kiv cua, tag nrho cov tswv cuab, brackets thiab cov girders uas nyob ib sab lossis lwm qhov chaw nyob hauv ib lub vojvoog ntawm tsawg kawg yog 1.5 zaug txoj kab uas hla ntawm lub kiv cua, Lub web xaus, brackets thiab bulkheads ntawm girders uas yuav raug kev nyuaj siab shear ntau dua.

2. Ntxiv rau kev suav qhov siab ntawm vuam ceg raws li vuam coefficient hauv qhov tshwj xeeb, nws tseem yuav tsum tau hais tias lub vuam ceg ntawm cov hlua vuam yuav tsum siab tshaj lossis sib npaug li 3 hli, tab sis nws tsis tas yuav tsum tau tshaj 1.5. lub sij hawm lub thickness ntawm tus neeg nyias nyias tsis hais txog ntawm daim ntawv weld thiab vuam txoj kev. Qhov siab ntawm weld ceg ntawm qhov tsis txuas txuas yog feem ntau tsis ntau tshaj 7 hli.

3. Thaum siv cov vuam sib txuas, qhov qhwv lub kaum sab xis ntev ntawm cov ntiv taw ntiv taw kawg yuav tsum tsis txhob tsawg dua qhov siab ntawm qhov sib txuas, thiab tsis pub tsawg dua 75 hli; qhov kawg ntawm qhov profile, tshwj xeeb tshaj yog thaum kawg yog tapered, qhov ntev ntawm lub kaum sab xis yuav tsum yog qhov siab ntawm qhov profile los yog qhov ntev ntawm lub bevel tsis tsawg tshaj li qhov txiav ntev, qhov twg yog qhov loj dua; txoj kev sib tshuam ntsug nruab nrab ntawm qhov kawg ntawm ntau qhov qhib thiab txiav thiab cov kev sib txuas ntawm cov tswv cuab yuav tsum tsis pub tsawg dua 75 hli; qhov ntev ntawm qhov tsis txuas txuas txuas yog feem ntau tsis pub tsawg dua 15 npaug ntawm cov phaj tuab lossis 75 hli, qhov twg ntau dua. Tus me

Kev xav tau kev paub ntxiv

Ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua ntawm kev tsim kho tshwj xeeb, lub nkoj nkoj kuj ntxiv raws li qhov yuav tsum tau ua ntawm lub tuam txhab tsim, xyoo ntawm kev tsim khoom thiab cov ntaub ntawv tawm tswv yim los ntawm tus tswv lag luam:

1. Sab tiv thaiv - kev sib tsoo fenders yuav tsum tau txuas ntxiv mus rau ob sab ntawm cov longitudinals hauv lub nkoj;

2. Lub fillet welds ntawm tag nrho cov Cheebtsam nyob rau hauv lub seawater ballast tank yuav tsum tas li welded rau ob sab;

3. Lub hauv qab - lawj thav duab lossis kab teeb sib txuas rau lub taub hau sab saud yuav tsum tau txuas txuas ntxiv rau ob sab;

4. Cov qauv sib txuas cov khoom siv mooring, cranes, davits, kab, masts thiab lub hull thiab cov khoom nyob ze yuav tsum yog ob npaug -sided txuas txuas ntxiv;

5. Cov cheeb tsam uas cov dej condensed tuaj yeem ua rau lub sijhawm ntev yuav tsum tau welded tsis tu ncua ntawm ob sab;

6. Tag nrho cov ces kaum arcs thiab chamfered ces kaum yuav tsum tau welded tsis tu ncua ntawm ob sab;

7. Cov welds ntawm lub brackets yog tag nrho ob npaug -sided nruam vuam;

8. The perimeter structure of the deck or bulkhead opening is to be continuously welded on both sides.
