Nā Nozzles Pāpā ʻAlua Venturi

Loaʻa maʻamau ʻo Blasting Nozzles i ʻelua ʻano kumu: pololei pololei a me venturi, me nā ʻano like ʻole o nā nozzles venturi.

Hoʻokaʻawale ʻia nā nozzles Venturi i nā nozzles venturi hoʻokahi-inlet a me nā nozzles venturi lua-inlet.

ʻO ka nozzle venturi hoʻokahi he nozzle venturi maʻamau. Hoʻolālā ʻia ia i loko o kahi komo hoʻololi lōʻihi i hoʻopaʻa ʻia, me kahi ʻāpana pololei palahalaha pōkole, a ukali ʻia e kahi hopena diverging lōʻihi e ākea a hiki i ka hopena puka o ka nozzle. Hoʻolālā ʻia kēia ʻano e hana i kahi hopena e hoʻolalelale nui i ka ea a me nā ʻāpana a puʻunaue like i ka abrasive ma luna o ke ʻano pahū holoʻokoʻa, e hāʻawi ana ma kahi o 40% ʻoi aku ka nui o ka hana ma mua o ka nozzle pololei.

Hiki ke noʻonoʻo ʻia ka nozzle venturi ʻelua ma ke ʻano he ʻelua nozzles me kahi ʻāpana a me nā lua ma waena e hiki ai ke hoʻokomo ʻia ka ea lewa i loko o ka ʻāpana o lalo o ka nozzle. ʻOi aku ka laulā o ka hopena puka ma mua o ka nozzle blast venture maʻamau. Hāʻawi ʻia nā nozzles venturi pālua ma kahi o 35% ka nui o ka hoʻoheheʻe ʻana ma mua o ka venturi blast nozzle maʻamau me kahi poho liʻiliʻi i ka wikiwiki abrasive. Ma ka hāʻawi ʻana i kahi kumu hoʻohālike nui, hiki i ka nozzle blast abrasive ke hoʻonui i ka pono o ka pahū abrasive. He kūpono ia no nā hana kahi e pono ai ke ʻano hoʻoheheʻe ākea.

Ma BSTEC, hiki iā ʻoe ke ʻike i nā ʻano nozzles pālua venturi.

1. Hoʻokaʻawale ʻia e ka Nozzle Liner Material

Silicon Carbide Double Venturi Nozzle:ʻO ke ola lawelawe a me ka lōʻihi e like me ka tungsten carbide, akā ma kahi o hoʻokahi hapakolu o ke kaumaha o nā nozzles tungsten carbide. He koho maikaʻi loa nā nozzles Silicon carbide i ka wā lōʻihi nā mea hana a makemake lākou i nā nozzle māmā.

ʻO Boron Carbide Double Venturi Nozzle:ka mea lōʻihi loa i hoʻohana ʻia no nā nozzles pahū. ʻOi aku ka maikaʻi o ka tungsten carbide e ʻelima a ʻumi mau manawa a me ka carbide silika i ʻelua a ʻekolu mau manawa ke hoʻohana ʻia nā abrasives ikaika. He mea kūpono ka nozzle boron carbide no nā abrasive hoʻopaʻapaʻa e like me ka alumini oxide a me nā hui mineral i koho ʻia ke pale ʻia ka hana ʻino.

2. Hoʻokaʻawale ʻia e ke ʻano Uila

Uila (Contractor) Thread:ʻO ke kaula maʻamau o ka ʻoihana ma 4½ mau ʻīniha (TPI) (114mm), hoʻemi nui kēia ʻano i ka manawa o ke kaula kea a ʻoi aku ka maʻalahi o ka hoʻouka ʻana.

Laulā maikaʻi(NPSM Thread): ʻO ka National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) ʻo ia ke kaula pololei maʻamau maʻamau i hoʻohana nui ʻia ma ʻAmelika ʻAmelika.

3. Hoʻopili ʻia e ka Nozzle Jacket

Kāleka Aluminum:hāʻawi i kahi kiʻekiʻe kiʻekiʻe o ka pale ʻana i ka pōʻino hopena ma ka māmā.

Kāleka kila:hāʻawi i kahi kiʻekiʻe kiʻekiʻe o ka pale ʻana i ka pōʻino hopena i ke kaumaha kaumaha.
