Kev Tua Xuab Zeb - Tseeb thiab Yooj Yim

Kev siv xuab zeb tua siv cua compressed ua lub zog tseem ceeb los tsuag cov khoom siv abrasives tsis sib xws ntawm qhov ceev ceev rau ntawm qhov chaw ua haujlwm. Nws qhov chaw tseem ceeb yog kev ntxuav + kev ua kom raug, nrog rau cov haujlwm tshem tawm ntxiv. Nws yog ib qho txheej txheem tseem ceeb ua ntej rau kev txau thiab electroplating tom qab.

Lub zog tuaj yeem hloov kho tau yooj yim: lub zog cua rau kev tua xuab zeb-pub siab yog 0.5–0.7 MPa, thiab rau kev tua xuab zeb-pub nqus yog 0.3–0.5 MPa. Kev tua xuab zeb-pub siab siab (kev tua xuab zeb ntub) tuaj yeem siv tau rau qee qhov xwm txheej. Cov xov xwm suav nrog cov khoom siv abrasives ntse-ntug xws li xuab zeb quartz, alumina fused xim av, thiab cov plhaub walnut zoo rau ib puag ncig. Qhov loj me ntawm cov khoom raug xaiv raws li qhov yuav tsum tau ua ntawm qhov chaw; G120–G80 grit raug pom zoo rau qib tshem tawm xeb Sa2.5.

Nws lub hom phiaj tseem ceeb yog kom tshem tawm cov roj, cov txheej qub, thiab xeb ntawm qhov chaw ua haujlwm, tswj qhov roughness ntawm qhov chaw, thiab txhim kho qhov lo rau ntawm cov txheej tom ntej. Nws kuj tseem siv tau rau kev kos duab thiab kev kho kom zoo nkauj ntawm cov khoom siv hluav taws xob.

Nws yog qhov tsim nyog rau cov khoom me me, ntau yam, thiab cov khoom ua haujlwm zoo sib xws, xws li pwm, cov khoom txhuas nyias nyias, thiab kev tshem tawm xeb hauv zos ntawm cov ntu nkoj. Nws yog tus phooj ywg zoo dua rau cov hlau mos thiab cov ntawv nyias nyias kom tsis txhob muaj kev hloov pauv, thiab ua raws li GB / T 8923.1 tus qauv tshem tawm xeb.

Kev Tua Phom - Tseeb thiab Ua Kom Pom Tseeb

Zoo ib yam li kev siv tshuab xuab zeb tua hluav taws xob, kev siv tshuab tua xuab zeb siv cua compressed lossis lub zog centrifugal me me los tsuag cov tshuaj tsuag puag ncig ntawm qhov chaw ua haujlwm nrog kev kub ceev. Nws tsom mus rau kev ua kom lub ntsej muag muaj zog thiab tsim nyog rau kev kho cov chaw nyuaj.

Lub zog hloov tau yooj yim, tso cai rau kev tswj hwm lub kaum sab xis thiab qhov ceev ntawm cov tshuaj tsuag, ua rau nws haum rau cov qhov hauv thiab cov ces kaum uas nyuaj uas tsis tuaj yeem npog los ntawm kev tua tshuaj tsuag. Cov xov xwm, zoo ib yam li cov siv hauv kev tua tshuaj tsuag, yog cov tshuaj tsuag puag ncig nrog txoj kab uas hla ntawm 0.1–2.0 hli. Lawv muaj cov nplaim du, tsis khawb cov khoom ua haujlwm ntau dhau, thiab rov ua dua tshiab tau.

Nws lub luag haujlwm tseem ceeb yog ua kom qhov chaw tawv, lub zog qaug zog, thiab kev tiv thaiv kev hnav los ntawm kev ua haujlwm tawv, thaum tseem muab kev kho kev ntxhov siab thiab kev tshem tawm cov kab nrib pleb. Nws cov nyhuv ntxuav tsis muaj zog dua li kev tua xuab zeb.

Cov xwm txheej siv tau suav nrog kev txhawb zog hauv zos ntawm cov khoom tseem ceeb xws li cov iav tsheb, cov khoom siv dav hlau, thiab cov kabmob. Nco ntsoov tias cov khoom ua haujlwm nrog cov roj saum npoo av yuav tsum tau ntxuav ua ntej kom tsis txhob muaj kuab paug rau cov duab thiab cuam tshuam rau cov txiaj ntsig.

Kev Tua Hluav Taws Xob - Ua Ib Pawg thiab Zoo

Kev tua phom siv lub zog centrifugal ua lub zog tseem ceeb. Lub impeller tig ceev ceev (lub log tua phom) pov cov phom puag ncig nrog kev nrawm nrawm rau ntawm qhov chaw ua haujlwm. Nws tsom mus rau kev ntxuav ua ke + kev ua kom lub ntsej muag muaj zog, muaj qib siab ntawm kev ua haujlwm tsis siv neeg, thiab yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoom loj.

Hais txog lub zog, qhov ceev ntawm lub impeller tuaj yeem ncav cuag 1500–3000 r/min, thiab qhov pib tua ceev yog txog li 100 m/s. Nws tsis vam khom lub tshuab cua compressor thiab muab qhov sib piv ntawm kev siv hluav taws xob zoo dua li ob txoj hauv kev siv ntev, nrog kev ua haujlwm ntau dua 30% siab dua li kev tua xuab zeb tes. Cov xov xwm yog cov txhaj tshuaj puag ncig, tsis muaj ntug, feem ntau yog cov txhaj tshuaj hlau lossis cov txhaj tshuaj hlau tsis xeb, nrog lub cheeb ntawm 0.8–2.5 hli. Lawv tuaj yeem rov ua dua ntau pua zaus, tsuas yog xav tau kev rov ua dua tas li (kev rov ua dua ≤ 10% ntawm tag nrho cov ntim).

Nws lub luag haujlwm tseem ceeb yog tshem tawm cov oxide nplai, molding xuab zeb, thiab xeb ntawm cov castings thiab forgings, thaum ua kom qhov nyuaj ntawm qhov chaw thiab kev qaug zog los ntawm kev ua haujlwm hardening thiab txo kev ntxhov siab sab hauv.

Cov xwm txheej siv tau yog feem ntau yog cov khoom siv ntau ntau, xws li cov phaj hlau, cov pej thuam cua tshuab, thiab cov khoom siv hauv lub tsheb. Nws tuaj yeem ua ke nrog cov kab conveyor tsis siv neeg rau kev tsim khoom tas mus li, ua raws li JB / T 8355 cov qauv khoom siv thiab GB / T 8923.1 tus qauv tshem tawm xeb.
