Tsis paub yuav xaiv blast nozzle li cas? Ua raws li plaub kauj ruam, nws yooj yim!

--Four cov kauj ruam qhia koj yuav ua li cas xaiv cov blast nozzles tsim nyog

 

Sandblasting nozzles yog tsim los ntawm ntau hom nrog ntau qhov ntau thiab tsawg thiab cov duab los ntawm ntau yam ntaub ntawv. Xaiv txoj cai sandblast nozzle rau txhua daim ntawv thov tsuas yog ib qho teeb meem ntawm kev nkag siab txog qhov hloov pauv uas cuam tshuam rau kev ua haujlwm tu thiab cov nqi ua haujlwm. Yog tias koj tsis paub yuav xaiv lub nozzle haum rau koj tus kheej li cas, ua raws li 4 kauj ruam hauv qab no.

1. Xaiv lub Nozzle Bore Size

Thaum xaiv lub nozzle, nws pib nrog kojcua compressor. Thaum koj nkag siab tias qhov luaj li cas ntawm koj lub compressor cuam tshuam rau kev tsim khoom, ces koj yuav xav saibnozzle loj. Xaiv lub nozzle nrog me me dhau ntawm lub bore thiab koj yuav tau tso qee lub peev xwm tawg rau ntawm lub rooj. Loj heev ntawm lub bore thiab koj yuav tsis muaj lub siab rau blast productively.

Cov lus hauv qab no qhia txog kev sib raug zoo ntawm qhov ntim ntawm huab cua, qhov loj me, thiab lub siab lub taub hau thiab feem ntau siv hauv kev lag luam los xaiv qhov loj me. Nws qhov txiaj ntsig tiag tiag yog xaiv qhov zoo tshaj plaws nozzle loj rau lub nozzle siab xav tau los ua haujlwm.

2. Xaiv lub Nozzle Shape

Tom ntej no yog lubzoo li nozzle. Nozzles tuaj nyob rau hauv ob lub hauv paus duab:Sncaj borthiabVentur, nrog ntau qhov kev hloov pauv ntawm Venturi nozzles.

Ncaj Bore nozzles(Number 1) tsim cov qauv nruj nreem rau qhov chaw blasting lossis blasting txee ua haujlwm. Cov no yog qhov zoo tshaj plaws rau cov hauj lwm me me xws li kev tu qhov chaw, weld seam shaping, ntxuav tes, kauj ruam, grillwork, los yog carving pob zeb thiab lwm yam ntaub ntawv.

Venturi bore nozzles(Tus lej 2 thiab 3) tsim cov qauv dav dav thiab ua kom nrawm nrawm dua li 100% rau qhov muab siab.

Venturi nozzles yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoom ntau dua thaum tawg qhov loj dua. Ob chav venturi thiab dav caj pas nozzles yog kho dua tshiab ntawm qhov ntev venturi style nozzle.

Covob venturistyle (Number 4) tuaj yeem xav tias yog ob lub nozzles hauv koob nrog qhov sib txawv thiab qhov nyob nruab nrab kom tso cai rau cov cua nkag mus rau hauv ntu ntu ntawm lub nozzle. Qhov kawg ntawm kev tawm kuj yog dav dua li cov pa nozzle. Ob qho kev hloov kho yog tsim los ua kom qhov loj me ntawm cov qauv tawg thiab txo qhov poob ntawm qhov nrawm nrawm.

Lub caj pas dav nozzles(Number 5) feature ib tug loj nkag caj pas thiab ib tug loj diverging tawm bore. Thaum sib txuam nrog tib qhov loj hose lawv tuaj yeem muab 15% nce hauv cov khoom lag luam tshaj cov nozzles nrog lub caj pas me. Nws kuj yog ib lub tswv yim zoo kom muaj lub kaum ntse ntse nozzles rau cov chaw nruj xws li nkauj nyab lattice, qab flanges, lossis hauv cov kav dej. Ntau tus neeg ua haujlwm nkim abrasives thiab sijhawm tos rau ricochet kom ua tiav txoj haujlwm. Lub sijhawm me ntsis nws yuav siv sij hawm hloov mus rau ib qholub kaum sab xis nozzleyog ib txwm zoo rov qab sai, thiab tag nrho lub sij hawm ntawm txoj hauj lwm raug txo.

3. Xaiv cov khoom Nozzle

Thaum koj tau txiav txim siab lub nozzle loj thiab cov duab, koj yuav xav txog qhovkhoomlub nozzle liner yog ua los ntawm. Peb lub ntsiab tseem ceeb hauv kev xaiv cov khoom zoo tagnrho nozzle bore yog durability, cuam tshuam tsis kam, thiab nqi.

Kev xaiv cov khoom siv nozzle nyob ntawm seb qhov abrasive koj xaiv, ntau npaum li cas koj tawg, qhov loj ntawm txoj haujlwm, thiab qhov nruj ntawm qhov chaw ua haujlwm. Nov yog cov lus qhia dav dav rau kev siv ntau yam ntaub ntawv.

Tungsten carbide nozzles:Ua tau muab lub neej ntev thiab kev lag luam thaum tuav tsis tau. Haum rau blasting slag, iav, thiab ntxhia abrasives.

Silicon carbidenozzles:Impact resistant thiab ruaj zoo li tungsten carbide, tab sis tsuas yog ib feem peb ntawm qhov hnyav ntawm tungsten carbide nozzles. Ib qho kev xaiv zoo tshaj plaws thaum cov neeg ua haujlwm nyob hauv txoj haujlwm ntev thiab nyiam lub teeb yuag nozzle.

Boron carbide nozzles:Tsis tshua muaj zog thiab ruaj, tab sis nkig. Boron carbide yog qhov zoo tagnrho rau kev txhoj puab heev xws li aluminium oxide thiab xaiv cov ntxhia aggregates thaum tuav ntxhib tuaj yeem zam tau. Boron carbide feem ntau yuav outwear tungsten carbide los ntawm tsib mus rau kaum zaug thiab silicon carbide los ntawm ob mus rau peb zaug thaum siv cov abrasives txhoj puab heev. Nqe kuj yog qhov siab tshaj ntawm lawv.

4. Xaiv cov xov thiab lub tsho

Thaum kawg, koj yuav tsum xaiv cov khoom ntawm lub tsho tiv thaiv lub bore. Koj kuj yuav tsum xav txog qhov style ntawm xov zoo tshaj plaws rau koj cov kev xav tau sandblasting: xov zoo los yog ntxhib (tus neeg cog lus) xov.

1) Nozzle Jacket

Aluminium Jacket:Aluminium Jackets muaj kev tiv thaiv siab heev tiv thaiv kev puas tsuaj hauv qhov hnyav.

Hlau Jacket:Cov tsho steel muaj kev tiv thaiv siab heev tiv thaiv kev puas tsuaj hauv qhov hnyav.

Rubber Jacket:Lub tsho roj hmab yog lub teeb hnyav thaum tseem muab kev tiv thaiv kev cuam tshuam.

2) Xov hom

Coarse (Cov neeg cog lus) Xov

Kev lag luam-tus qauv xov ntawm 4½ threads ib nti (TPI) (114mm), qhov style no zoo heev txo lub caij nyoog ntawm kev hla xov thiab yooj yim dua rau nruab.
