Kev Tshawb Fawb Txog Kev Tshawb Fawb Thiab Kev Sib Tham Ntawm Generators

(1) Kev puas tsuaj ntawm cov ntaub so ntswg

Cov txiaj ntsig ntawm kev ntsuam xyuas metallographic pom tias muaj qhov pom tseeb zonal cais hauv cov khoom.Band microstructure yog lub microstructure tsim raws li cov kev taw qhia ntawm cov hlau, feem ntau yog tsim los ntawm proeutectoid ferrite thiab pearlite.Vim muaj qhov sib txawv microstructure thiab cov khoom ntawm cov hlua uas nyob ib sab, kev nyuaj siab concentration yuav inevitably tshwm sim ntawm lub zog thiab tsis muaj zog bands, uas ua rau tag nrho poob ntawm txhua yam khoom thiab pom tseeb anisotropy.Nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, delamination tearing tshwm sim yooj yim raws cov qauv sawb, uas nteg lub hauv paus rau qhov tsis ua hauj lwm thaum ntxov ntawm cov khoom.

(2) Keeb kwm ntawm banded lug

Cov qauv sawb yog cov qauv tsis xws luag hauv cov hlau tsis tshua muaj hlau, uas yog tshwm sim los ntawm ob qho laj thawj: ua ntej, kev xaiv crystallization ntawm molten steel thaum lub sij hawm crystallization txheej txheem ntawm steel ingot ua rau tsis sib xws ntawm cov qauv dendrite.Thaum lub sij hawm dov txheej txheem, cov ntxhib dendrite elongates thiab maj mam ua raws li cov kev taw qhia ntawm deformation, yog li tsim lub superposition ntawm depleted thiab enriched bands ntawm carbon thiab alloy ntsiab.Nyob rau hauv tus txheej txheem ntawm qeeb txias, ferrite thiab pearlite feem ntau yog banded lug.Nyob rau hauv cov ntaub ntawv no, compositional banding yog lub hauv paus thiab prerequisite rau cov ntaub so ntswg banding.Yog li cov pa annealing normalizing yog qhov nyuaj rau kev tshem tawm, tsuas yog los ntawm kev kub siab diffusion annealing thiab normalizing ib zaug lossis peb zaug los txhim kho lossis tshem tawm.

Qhov thib ob yog vim li cas lub koom haum ribbon tshwm sim los ntawm kev ua haujlwm kub tsis zoo.Thaum lub kub dov kub nyob rau hauv ob-theem cheeb tsam, ferrite yog precipitated los ntawm austenite nyob rau hauv bands raws cov hlau ntws, thiab cov undecomposed austenite muab faib ua bands.Thaum txias rau A1, banded austenite hloov mus rau hauv banded pearlite.Banded qauv tuaj yeem txhim kho thiab tshem tawm los ntawm normalizing lossis annealing.

(3) Kev simulation sim ntawm kev tshem tawm cov qauv banded

Txhawm rau txiav txim siab qhov laj thawj ntawm kev sib cais thiab tshem tawm nws, 20 steel tau normalized raws li cov txheej txheem kev kho cua sov.Cov qauv kho metallographic (saib daim duab 6) qhia tias cov qauv banded ntawm lub scaffold tau txhim kho zoo, qhia tias cov qauv banded ntawm lub scaffold yog tshwm sim los ntawm kev kho cua sov tsis zoo, uas tuaj yeem txhim kho thiab tshem tawm tom qab kev kho kom zoo.Yog li ntawd, sab hauv ua rau ntawm scaffold tawg thiab nws cov kev txhim kho kev ntsuas yog nrhiav los ntawm nam ntawm cov khoom microstructure.

(4) Kev tsom xam

Los ntawm kev tsim thiab ua tiav ntawm cov qauv sab nraud ntawm lub bracket, tag nrho cov duab ntawm lub bracket yog ntxhib, lub weld yog pom tseeb, riam cov cim thiab qhov pits tuaj yeem pom nyob txhua qhov chaw, qhia tias tag nrho cov kev ua haujlwm tsis zoo.Raws li tuaj yeem pom los ntawm cov qauv thiab qhov chaw tawg ntawm kev txhawb nqa hauv FIG.1, qhov tawg tau tshwm sim ntawm lub ces kaum ntawm kab rov tav thiab ntsug steel daim hlau, uas yog Ameslikas ib qho kev sib txuas tsis muaj zog hauv kev tsim qauv.Yuav tsum muaj arc hloov chaw kom txo qis kev ntxhov siab, tab sis muaj cov kauj ruam sib txawv.Xws li pom tseeb machining defects yuav undoubtedly ua rau kev nyuaj siab concentration zones, uas yuav qhib raws rau tawg pib thiab kev loj hlob.

Nyob rau hauv cov nqe lus ntawm tag nrho cov txheej txheem ntawm kev them nyiaj yug, lub kub-kuav los tiag steel phaj tsis normalized ua ntej siv, los yog tsis ua raws li lub cev thiab tshuaj ntsuam xyuas, uas ua rau cov raw cov ntaub ntawv nrog cov yam ntxwv tsis xws luag ncaj qha mus rau lub tom ntej no txheej txheem.Tsis tas li ntawd, cov hlau phaj ntawm kev txhawb nqa tsis yog annealed lossis normalized tom qab vuam, uas yuav ua rau muaj kev ntxhov siab ntawm vuam seem thiab ua kom cov txheej txheem tawg tawg ntawm kev txhawb nqa rau qee yam.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Suav teb, uas integrates tsim, muab, commissioning thiab txij nkawm. diesel generator teeb .Cov khoom npog Cummins , Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai thiab lwm yam nrog lub hwj chim ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab lub chaw thev naus laus zis.
