Dab tsi ua rau hopper fabrication txawv
Lub hauv paus ncej yog tsim los ntawm cov tswv cuab uas raug txiav, haum thiab welded. Lub hopper yog tsim los ntawm cov vaj huam sib luag loj uas yuav tsum tau ua lub kaw peb-dimensional zoo nrog qhov tseeb inlet thiab qhov hluav taws xob geometry. Qhov nyuaj tsis yog qhov vuam nws tus kheej; nws tuav cov duab thaum lub vuam tshwm sim.
Plaub yam xwm txheej tsav feem ntau ntawm cov phiaj xwm tsim khoom:
Vaj huam sib luag loj piv rau thickness.Ib tug loj, kuj nyias vaj huam sib luag welded raws ib tug ntug yuav nyo rau lub weld. Thaum bowed, nws yuav siv lub qhov hluav taws xob flange nrog nws.
Hloov geometry.Qhov twg ib lub qhov hluav taws xob sib ntsib nrog lub qhov hluav taws xob nqaim, los yog ib qho kev sib tw ua tau raws li lub thawv square, cov ntawv hloov pauv yog ob npaug nkhaus lossis skewed. Fit-up qhov khoob tshwm sim yog tias cov duab tsim tsis raug.
Flange flatness.Lub flange yog lub interface. Nws yuav tsum tiaj tus thiab nws lub qhov qauv yuav tsum yog, los yog lub chute yuav xau, vibrate xoob, los yog tsis txuas.
Hnav thiab hloov tau.Yog tias cov khoom siv los yog cov khoom hloov pauv tau yog ib feem ntawm qhov tsim, kho qhov yuav tsum tau drilled kom phim tus niam txiv qauv tom qab nws tau welded, tsis yog ua ntej.

Tsim cov duab ua ntej welding
Txoj kev txhim khu kev qha tshaj plaws los tuav hopper geometry yog sib sau ua ke los ntawm cov vaj huam sib luag ua ntej nyob rau hauv ib ntus thav duab lossis fixture, thiab txheeb xyuas qhov qhib qhov ntev thiab kab pheeb ces kaum sib npaug.ua ntejtag nrho vuam. Tacking, kuaj xyuas, kho thiab tsuas yog tom qab ntawd welding qeeb qeeb ntawm daim ntawv thiab sai dua hauv kev xyaum, vim tias kev kho lub siab welded hopper txhais tau tias txiav seams.
Kev sib dhos kev taw qhia yog ib feem ntawm txoj kev npaj ntawd. Ib qho kev hloov pauv ntawm hom no feem ntau ua rau loj-qhib-hauv pem teb: lub ntsej muag dav muab lub hauv paus ruaj khov ntawm cov ntoo thaiv, lub qhov hluav taws xob xaus rau ntawm qhov siab ua hauj lwm rau kev sib tsoo thiab vuam, thiab plaub lub kaum sab xis tuaj yeem ua los ntawm sab nraud yam tsis muaj scaffolding. Lub rooj sib txoos yog tig tsuas yog tom qab lub geometry yog welded thiab xyuas.
Cov braces ib ntus yog siv los txhob txwm tshaj tawm: ib kab pheeb ces kaum los yog lub qhov rooj sib txuas tuav lub qhov hluav taws xob qhib thaum lub seams yog welded nqi ob peb teev thiab tiv thaiv lub qhov hluav taws xob los ntawm kev kaw los ntawm ob peb millimeters. Cov braces raug tshem tawm tsuas yog tom qab lub rooj sib txoos txias thiab cov seams tiav lawm.
Seam sequencing ntawm lub phaj loj
Ntev nruam seams yog qhov tseem ceeb ntawm vaj huam sib luag hneev nti. Qhov twg qhov tshwj xeeb tso cai, seams yog welded nyob rau hauv alternating luv luv khiav, sib npaug nyob rau hauv lub centreline, thiab ua kom tiav nyob rau hauv ib tug sib lawv liag uas cia txhua qhov chaw txias ua ntej lub tshav kub input tom ntej tuaj txog. Qhov twg ib qho txuas txuas txuas ntxiv yuav tsum ua haujlwm - kev ntim khoom, piv txwv li - cov kab ke tau npaj ua tib zoo ntau dua li qhov vuam tau ua me me, vim tias txoj kev xau tsis tuaj yeem hloov pauv rau flatness.
Stiffeners: pab thiab txaus ntshai
Stiffeners tiv thaiv vaj huam sib luag hneev tab sis kuj mloog zoo rau cua sov. Ib tug stiffener welded nrog ib tug oversized fillet ntawm ib sab yuav rub lub vaj huam sib luag rau hauv ib tug pom hollow. Txoj hauv kev ua tau zoo yog siv cov stiffener layout los ntawm kev kos duab, khaws cov fillet qhov ntau thiab tsawg ntawm qhov kos duab yam tsawg kawg nkaus, thiab weld stiffeners nyob rau hauv ib qho kev sib npaug es tsis ua kom tiav txhua tus hauv ib qho dhau los.
Flanges thiab interfaces
Lub flange yog qhov chaw fabrication zoo pom rau cov neeg siv khoom, vim nws yog bolts los yog nws tsis. Peb tswj qhov tseem ceeb:
Flange flatness- kuaj xyuas tom qab vuam, kho los ntawm machining lossis los ntawm kev tswj kev ncaj, tsis yog los ntawm kev sib tw bolts ntawm qhov chaw.
Qhov qauv- drilled los yog machined tom qab lub flange yog welded thiab tiaj tus, los ntawm ib tug datum uas muaj feem xyuam rau lub rooj sib txoos, tsis mus rau lub phaj ntug.
Kev taw qhia- match-cim thiab stamped ces qhov mating yog haum nyob rau hauv qhov tseeb tig. Ib lub flange uas haum nkaus xwb nyob rau hauv ib qho kev taw qhia haum tsis zoo rau lwm qhov peb.
Qhov twg lub hopper txuas mus rau cov khoom yuav khoom, qhov ntev ntawm lub flange mating yog muab los ntawm cov khoom siv kos duab los yog cov qauv muab khoom, tsis yog inferred los ntawm nominal loj.
Lub chute flange drilled tom qab vuam: lub ntsej muag tiaj tus, kho lub qhov qauv thiab cov cim taw qhia rau kev sib dhos.
Hnav cov hnab looj tes thiab cov seem hloov tau
Cov paib liner, bolted coj tuav thiab cov chute hloov tau yog tsim kom lawv cov qhov kho kom haum rau cov qauv niam txiv welded. Qhov sib lawv liag yog: weld tus niam txiv, txheeb xyuas nws cov geometry, tom qab ntawd laum los yog sib tw-xov lub liner rau nws, ces sim-haum. Drilling ob qho tib si los ntawm kev kos duab ntawm nws tus kheej yog qhov ua rau ib txwm muaj cov kab uas xav tau reaming ntawm qhov chaw.
Kev xaiv cov khoom siv rau cov ntaub ntawv - cov hlau me me, cov phaj tsis zoo, tsis muaj hlau, lossis cov ntaub ntawv tsis yog xim hlau - nyob ntawm cov khoom siv, qhov loj me, cuam tshuam lub zog thiab ya raws. Qhov kev xaiv ntawd yog kev txiav txim siab tsim. Fabrication tuaj yeem ua haujlwm rau ib qho ntawm cov no thaum qhov kev xaiv tau teev rau ntawm daim duab.
Liner sim haum: kho qhov sib tw-drilled rau cov qauv niam txiv welded, ces lub phaj yog lifted tawm rau txheej.
