Ob chav Venturi Blasting Nozzles 

Blasting Nozzles feem ntau tuaj nyob rau hauv ob qho yooj yim cov duab: ncaj bore thiab venturi, nrog rau ntau yam ntawm venturi nozzles.

Venturi nozzles feem ntau muab faib ua ib leeg-inlet venturi thiab ob-inlet venturi nozzle.

Ib qho venturi nozzle yog cov pa venturi nozzle. Nws yog tsim nyob rau hauv ib tug ntev tapered converging nkag, nrog ib tug luv luv ca ncaj seem, ua raws li los ntawm ib tug ntev diverging kawg uas widens thaum koj mus txog qhov kawg ntawm lub nozzle. Cov duab no yog tsim los tsim cov nyhuv uas ua kom nrawm nrawm ntawm cov huab cua thiab cov khoom sib npaug thiab sib npaug faib cov abrasive rau tag nrho cov qauv tawg, uas ua rau kwv yees li 40% ntau dua tus nqi ntau dua li lub taub hau ncaj.

Ob chav venturi nozzle 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 tus qauv venture blast nozzle. Ob chav venturi nozzles muab ib ncig ntawm 35% loj dua cov qauv tawg dua li cov pa venturi blast nozzle nrog tsuas yog poob me ntsis hauv qhov nrawm nrawm. Los ntawm kev muab cov qauv tawg loj, lub abrasive moj tej tawg nozzle ua rau muaj zog abrasive blast efficiency. Nws yog qhov zoo tagnrho rau cov haujlwm uas xav tau kev sib tw dav dav.

Hauv BSTEC, koj tuaj yeem pom ntau hom ob chav venturi nozzles.

1.     Lwm yam los ntawm Nozzle Liner Material

• Silicon Carbide Ob Chav Venturi Nozzle:Lub neej kev pab cuam thiab durability zoo ib yam li tungsten carbide, tab sis tsuas yog ib feem peb ntawm qhov hnyav ntawm tungsten carbide nozzles. Silicon carbide nozzles yog qhov kev xaiv zoo tshaj plaws thaum cov neeg ua haujlwm nyob rau hauv txoj haujlwm ntev thiab nyiam lub teeb yuag nozzles.

• Boron Carbide Ob Chav Venturi Nozzle:cov khoom siv ntev tshaj plaws siv rau kev tawg nozzles. Nws outwears tungsten carbide los ntawm tsib mus rau kaum zaug thiab silicon carbide los ntawm ob mus rau peb zaug thaum aggressive abrasives yog siv. Boron carbide nozzle yog zoo tagnrho rau aggressive abrasives xws li txhuas oxide thiab xaiv mineral aggregates thaum ntxhib tuav yuav zam tau.

2.    Classified los ntawm Xov Hom

• Coarse (Contractor) Xov:Kev lag luam-tus qauv xov ntawm 4½ threads ib nti (TPI) (114mm), qhov style no zoo heev txo txoj hauv kev ntawm kev hla xov thiab yooj yim dua rau nruab.

• Xov xwm zoo(NPSM Xov): National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) yog cov txheej txheem kev lag luam ncaj nraim siv dav hauv North America.

3.    Classified los ntawm Nozzle Jacket

• Aluminium Jacket:muab kev tiv thaiv siab heev tiv thaiv kev puas tsuaj hauv lub teeb yuag.

• Hlau Jacket:muab kev tiv thaiv siab heev tiv thaiv kev puas tsuaj hauv hnyav hnyav.
