Kev txhaj tshuaj blasting kuj yog lub npe ntawm cov txheej txheem kho tshuab nto, zoo ib yam li xuab zeb blasting thiab tua blasting.Kev txhaj tshuaj blasting yog txheej txheem kev kho mob khaub thuas, uas tau muab faib ua kev tua blasting tu thiab tua blasting ntxiv dag zog.Raws li lub npe qhia, txhaj tshuaj blasting tu yog tshem tawm impurities xws li nto oxide los txhim kho cov tsos zoo.Kev txhaj tshuaj blasting ntxiv dag zog yog siv high-ceev txav projectile (60-110m / s) ntws mus txuas ntxiv cuam tshuam rau saum npoo ntawm lub workpiece kom ntxiv dag zog.Qhov saum npoo thiab txheej txheej ntawm lub hom phiaj (0.10-0.85mm) raug yuam kom ua raws li cov kev hloov hauv qab no thaum lub sij hawm cyclic deformation: 1. Lub microstructure tau hloov kho;2. Cov khoom siv yas tsis yog txheej txheej sab nrauv qhia txog qhov seem compressive kev nyuaj siab, thiab sab hauv sab hauv ua rau residual tensile stress;3. Sab nrauv roughness hloov pauv (RaRz).Kev cuam tshuam: Nws tuaj yeem txhim kho qhov qaug zog puas ntawm cov ntaub ntawv / qhov chaw, tiv thaiv kev qaug zog tsis ua haujlwm, yas deformation thiab nkig tawg, thiab txhim kho lub neej qaug zog.
Lub hauv paus ntsiab lus ntawm kev txhaj tshuaj blasting txheej txheem:
Kev txhaj tshuaj blasting txhais tau hais tias cov khoom siv txhaj tshuaj (steel txhaj tshuaj) tau muab pov rau hauv qhov chaw ua haujlwm ntawm kev kub ceev thiab qee lub kaum sab xis los ntawm kev siv tshuab, kom cov khoom txhaj tshuaj muaj qhov cuam tshuam ceev ntawm qhov chaw ua haujlwm.Nyob rau hauv kev sib koom ua ke ntawm lub tshuab nqus tsev nqus tsev vacuum tsis zoo siab thiab rebound quab yuam, cov khoom txhaj tshuaj circulates nws tus kheej hauv cov khoom siv.Nyob rau tib lub sijhawm, cov khoom siv tshuaj tua kab thiab cov impurities ntxuav tau zoo li qub los ntawm kev ntxuav cov huab cua ntawm lub tshuab nqus tsev.Thiab ib qho txheej txheem uas tso cai rau cov pellets txuas ntxiv mus ua dua tshiab.Lub tshuab tau nruab nrog cov khoom siv plua plav kom ua tiav cov plua plav thiab tsis muaj kuab paug, uas tsis tsuas yog txhim kho kev ua haujlwm zoo tab sis kuj tiv thaiv ib puag ncig.Thaum lub tshuab ua haujlwm, cov pellet loj thiab cov duab ntawm cov pellet raug xaiv, thiab kev taug kev ceev ntawm cov cuab yeej raug kho thiab tswj kom tswj tau qhov projectile txaus ntawm cov pellet, thiaj li kom tau txais qhov sib txawv ntawm qhov projectile thiab tau txais kev kho deg sib txawv. teebmeem.
Cov kev cai ntawm kev txhaj tshuaj blasting txheej txheem:
Los ntawm kev tswj thiab xaiv qhov loj me thiab cov duab ntawm cov pellet, kho thiab teeb tsa kev taug kev ceev ntawm lub tshuab, tswj qhov projectile txaus tus nqi ntawm cov pellet, qhov sib txawv projectile siv thiab qhov sib txawv ntawm qhov kev kho mob tuaj yeem tau txais.Cov txheej txheem txhaj tshuaj blasting thiab cov cuab yeej siv tshuaj tua blasting tswj cov txheej txheem saum npoo tom qab kev kho mob los ntawm peb qhov tsis zoo raws li qhov sib txawv ntawm qhov yuav tsum tau kho.Xaiv qhov loj thiab cov duab ntawm cov pellet;Kev khiav ceev ntawm cov khoom siv;Tus nqi ntws ntawm pellets.Qhov saum toj no peb tsis koom tes nrog ib leeg kom tau txais kev kho mob sib txawv thiab xyuas kom meej qhov zoo tshaj plaws roughness ntawm qhov chaw tom qab txhaj tshuaj blasting.Piv txwv li: siv S330 steel txhaj tshuaj, ntws 10A, kev kho mob ntawm C50 pob zeb nto, tuaj yeem ncav cuag roughness ntawm 90;Los ntawm kev kho cov asphalt nto, cov txheej dej nyab tuaj yeem raug tshem tawm thiab qhov roughness yog 80. Thaum tuav cov hlau phaj, cov qauv kev huv ntawm SA3 tuaj yeem ncav cuag.
Kev txhaj tshuaj blasting yog txoj kev ntxuav, ntxiv dag zog rau (steev blasting) los yog polishing lub workpiece nrog txhaj tshuaj blasting tshuab, uas yog siv nyob rau hauv yuav luag tag nrho cov lag luam uas siv hlau, xws li aerospace, automotive, kev tsim kho, casting, shipbuilding, railways thiab ntau lwm yam lag luam. .Muaj ob txoj kev: tua blasting lossis xuab zeb blasting.
Thawj: txhaj tshuaj blasting tshuab:
1. Lub tshuab txhaj tshuaj blasting hloov lub cev muaj zog ncaj qha rau hauv lub zog abrasive zog los ntawm kev tig lub turbine impeller.
2, lub peev xwm ntawm txhua lub impeller los ntawm 60 kg ib feeb mus rau 1200 kg / feeb.
3, siv cov accelerators loj no, siv lub log zeb, qhov loj lossis qhov loj ntawm qhov chaw yuav tsum muaj qee yam xeb, descaling, deburring, tev lossis ntxuav.
4, Feem ntau, txoj kev tsheb thauj mus los ntawm cov khoom pov tseg yuav txhais tau tias hom tshuab: los ntawm cov duab yooj yim mus rau kev sib koom ua ke tsis siv neeg ua haujlwm rau ntau yam ntawm cov tuam txhab tsheb, ntawm cov menyuam conveyors thiab siv descaling systems.
Qhov thib ob: xuab zeb blasting tshuab:
1, cov xuab zeb blasting tshuab yuav siv tau nyob rau hauv daim ntawv ntawm blower los yog blower, lub moj tej tawg nruab nrab yog pneumatically ceev los ntawm compressed cua thiab projected rau lub Cheebtsam los ntawm lub nozzle.
2, rau kev siv tshwj xeeb, kev sib xyaw dej-dej tuaj yeem siv tau, uas yog hu ua ntub sandblasting.
3, nyob rau hauv huab cua thiab ntub sandblasting, lub nozzle tuaj yeem ntsia tau rau hauv qhov chaw ruaj khov, lossis tuaj yeem ua haujlwm manually lossis los ntawm cov neeg siv lub tshuab nozzle lossis PLC programmed automation system.
4, kev ua haujlwm sandblasting txiav txim siab qhov kev xaiv ntawm kev sib tsoo xov xwm, feem ntau tuaj yeem siv txhua hom kev sib tsoo lossis kev sib tsoo dawb.
