I-Double Venturi Blasting Nozzles

Ama-Nozzles aqhumayo ngokuvamile eza ngezimo ezimbili eziyisisekelo: i-straight bore ne-venturi, enokuhlukahluka okuningana kwemibhobho ye-venturi.

Imibhobho ye-Venturi ivamise ukuhlukaniswa abe i-single-inlet venturi kanye ne-double-inlet venturi nozzles.

I-venturi nozzle eyodwa i-venturi nozzle evamile. Idizayinelwe ngendlela yokungena eguqukayo ende ene-tapered, enesigaba esifushane esiyisicaba esiqondile, esilandelwa isiphetho eside esiphambukayo esinwebekayo njengoba ufika ekugcineni komlomo. Lo mumo uklanyelwe ukukhiqiza umthelela osheshisa kakhulu ukugeleza komoya nezinhlayiya futhi usabalalise ngokulinganayo ukuhuzuka kuyo yonke iphethini yokuqhuma, unikeze isilinganiso sokukhiqiza esikhulu esingaba ngu-40% kunembobo ebhobozayo eqondile.

I-double venturi nozzle ingacatshangwa njengamabhomu amabili ochungechungeni anegebe nezimbobo phakathi ukuze kuvunyelwe ukufakwa komoya osemkhathini engxenyeni engezansi yomfula. Isiphetho sokuphuma futhi sibanzi kune-standard venture blast nozzle. Imibhobho ye-venturi ephindwe kabili ihlinzeka cishe ngephethini yokuqhuma engu-35% enkulu kune-venturi blast nozzle evamile enokulahleka okuncane kuphela kwesivinini esibi. Ngokuhlinzeka ngephethini enkulu yokuqhuma, umlomo wombhobho oqhumayo uvumela ukwanda kokusebenza kahle kokuqhuma kwe-abrasive. Ilungele imisebenzi lapho kudingeka khona iphethini yokuqhumisa ebanzi.

Ku-BSTEC, ungathola izinhlobo eziningi ze-double venturi nozzles.

1. Ihlukaniswa nge-Nozzle Liner Material

I-Silicon Carbide Double Venturi Nozzle:impilo yesevisi nokuqina kufana ne-tungsten carbide, kodwa cishe ingxenye eyodwa kwezintathu yesisindo samabhomu e-tungsten carbide. Ama-nozzles e-silicon carbide ayisinqumo esihle kakhulu lapho opharetha besemsebenzini isikhathi eside futhi bekhetha imibhobho engasindi.

I-Boron Carbide Double Venturi Nozzle:into ehlala isikhathi eside esetshenziselwa imibhobho yokuqhuma. Igqoka i-tungsten carbide izikhathi ezinhlanu kuya kweziyishumi kanye ne-silicon carbide ngokuphindwe kabili kuya kathathu lapho kusetshenziswa ama-abrasives anolaka. Umbhobho we-boron carbide ulungele ama-abrasives anolaka njenge-aluminium oxide kanye nezinhlanganisela zamaminerali ezikhethiwe lapho ukuphatha kabi kungagwenywa.

2. Ihlukaniswa ngohlobo lwentambo

Uchungechunge Olumahlaza (Losonkontileka):Intambo esezingeni lomkhakha emicu engu-4½ iyintshi ngayinye (TPI) (114mm), lesi sitayela sehlisa kakhulu ithuba lokuwela futhi kulula kakhulu ukuyifaka.

Intambo Enhle(Uchungechunge lwe-NPSM): I-National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) iwuchungechunge olujwayelekile lwemboni olusetshenziswa kabanzi eNyakatho Melika.

3. Ihlukaniswe ngeJacket yeNozzle

Ijakhethi le-Aluminium:nikeza izinga eliphezulu kakhulu lokuvikela ekulimaleni komthelela ku-lightweight.

Ijakhethi Lensimbi:nikeza izinga eliphezulu kakhulu lokuvikela ekulimaleni komthelela ku-heavyweight.
