Cov Txheej Txheem Txhaum Txhaum Txhaum Cai Rau Cov Thawv Loader

Kev txhaj tshuaj blasting tu txheej txheem rau cov thoob loader
Cov thoob Loader yog loj, irregularly zoo li tus, siab -lub zog welded structural Cheebtsam. Lawv qhov chaw yog them nrog ntau qhov vuam slag, oxide nplai, xeb, thiab qhov txiav ntug yuav tsum tau ntxiv dag zog ib txhij. Cov txheej txheem tua blasting ua tiav yog raws li hauv qab no:
1. Kev npaj ua haujlwm: xaiv cov khoom siv thiab ua ntej- kho
1.1 Xaiv lub tshuab txhaj tshuaj blasting tsim nyog
Xaiv qhov loj -tonnage ob-hoist hom tua blasting tshuab (rau batch ntau lawm, los ntawm - hom hoist tua blasting tshuab tuaj yeem xaiv):
Lub hoist load yuav tsum siab tshaj los yog sib npaug li 1.2 npaug ntawm qhov hnyav ntawm lub thoob (rau lub thoob 5-tuj loader, ib qho hnyav yog 1-2 tons, xaiv 5-tuj hoist). Qhov luaj li cas ntawm qhov txhaj tshuaj blasting chamber yuav tsum loj dua qhov siab tshaj plaws ntawm lub thoob los ntawm 15% los yog ntau tshaj los xyuas kom meej qhov kev ncua deb ntawm 0.75-1.5 meters ntawm lub workpiece thiab txhaj tshuaj blasting tshuab, tsis txhob sib tsoo los yog tsis txaus ntuav deb.
Lub hoist yuav tsum muaj peev xwm ntawm 360℃tus kheej- kev sib hloov thiab yuav tsum tau nruab nrog ntau dua los yog sib npaug rau 6 txhaj tshuaj blasting pab kiag li lawm los npog lub puab kab noj hniav, weld seams, txiav ntug thiab lwm yam dig muag qhov chaw ntawm lub thoob.
1.2 Ua ntej-kev kho cov khoom ua haujlwm (cov ntsiab lus tseem ceeb ntawm kev tswj kom zoo)
Kev sib tsoo ua ntej- sib tsoo: Phau ntawv sib tsoo kom tshem tawm> 1mm weld spurs thiab vuam txaws - loj protrusions yuav ua rau txhaj koob tshuaj tivthaiv, ua rau tsis sib xws nto pitting thiab tsis tuaj yeem raug tshem tawm ncaj qha los ntawm kev txhaj tshuaj blasting.
Kaw lub qhov: Siv cov roj hmab ntsaws ntsaws rau hauv lub qhov pin ncej, xov qhov, thiab cov txheej txheem lub qhov los tiv thaiv kev txhaj tshuaj los ntawm embedded thiab cuam tshuam rau kev sib dhos tom ntej.
Center nrhiav: Kos lub hauv paus txoj hauj lwm ntawm lub thoob, xyuas kom meej qhov sib npaug thaum hoisting kom tsis txhob co thiab sib tsoo thaum tua blasting.
2. Core txhaj tshuaj blasting txheej txheem kev ua haujlwm thiab qhov ntsuas qhov ntsuas
1.1 Cov txheej txheem ua haujlwm ib ntus (tsis tuaj yeem thim rov qab)
Pib-nce: Pib lub tshuab tshem tawm plua plav → Pib lub elevator → Pib lub tshuab cais → Pib lub tshuab tua blasting ib qho los ntawm ib qho → Pib lub hoist nws tus kheej- kev sib hloov → Qhib lub pellet mov valve
Kev Ua Haujlwm: Lub hoist tsav lub thoob mus rau hauv qhov txhaj tshuaj blasting chamber thiab tsis tu ncua tig thiab cuam tshuam
Nres: Kaw lub pellet mov valve → Nres lub tshuab tua blasting → Lub hoist txuas ntxiv rau nws tus kheej - tig rau 1 feeb (kom tshem tawm cov pellets seem) → Nres lub elevator/seperator → Nthuav - nres lub tshuab tshem tawm plua plav
2. Kev teeb tsa ntawm cov txheej txheem tsis raug (hloov rau siab - lub zog steel loader thoob)
Kev xaiv txhaj tshuaj: S330 alloy steel pellets (inch 0.8-1.2mm), ntsuas kev tu kom zoo thiab txheej txheej roughness, txwv tsis pub siv cov hlau hlau txiav pellets (uas tuaj yeem ua rau ntau qhov roughness)
Txhaj tshuaj blasting tshuab kev sib hloov ceev: 2500-2800rpm
Hoist tus kheej- kev sib hloov ceev: 3-5r / min, kom ntseeg tau tias muaj kev cuam tshuam zoo rau txhua qhov chaw, thiab cov chaw dig muag tuaj yeem nres thiab kho lub hoist ncua kev kawm lub kaum sab xis thaum lub sijhawm txhaj tshuaj blasting txheej txheem
Lub sij hawm txhaj tshuaj blasting: 5-8 feeb, rau cov thoob khib nyiab loj heev txuas mus rau 10 feeb, rau cov thoob tshiab welded 5 feeb yog txaus
Kev tshem tawm plua plav tsis zoo: -15 ~ -20Pa, kom tsis txhob muaj plua plav tawm thiab xyuas kom meej qhov kev txhaj tshuaj blasting sib cais
3. Tshaj tawm - kev ua haujlwm thiab kev lees paub zoo
1. Tshaj tawm - cov txheej txheem ua haujlwm
Residual pellet tu: Siv 0.6-0.8MPa compressed cua los tshuab lub puab kab noj hniav, weld seams, thiab qhov muag tsis pom ntawm lub thoob kom tshem tawm tag nrho cov embedded pellets;
Re-ua hauj lwm rau cov welds tsis huv hauv zos thiab qhov muag tsis pom: 定点 re- blasting rau lub zos tsis huv welds thiab qhov muag tsis pom;
Kev tshuaj xyuas saum npoo: Paub meej tias tsis muaj qhov seem seem ua ntej hloov mus rau txheej txheej txheej.
2. Cov qauv kev lees paub zoo
Kev huv huv: Mus txog qib Sa2.5 (ze - qib dawb) - tsis pom oxide nplai, vuam spurs, los yog xeb ntawm qhov chaw, nthuav tawm cov xim hlau tsis sib xws;
Roughness: Nto roughness tswj ntawm Ra20-30μm, ua kom cov txheej tom ntej adhesion ncav cuag ISO 1 qib;
Tsis muaj pellets embedded: Tsis muaj pellets nyob rau hauv tag nrho cov qhov thiab qhov khoob, tsis cuam tshuam rau kev sib dhos tom ntej.
