ʻAʻole maopopo pehea e koho ai i ka nozzle blast? Ma hope o nā ʻanuʻu ʻehā, maʻalahi!

-- ʻEhā mau ʻanuʻu e haʻi iā ʻoe pehea e koho ai i nā nozzles blast kūpono

Hoʻolālā ʻia nā nozzles sandblasting i nā ʻano like ʻole me nā ʻano nui a me nā ʻano like ʻole mai nā mea like ʻole. ʻO ke koho ʻana i ka nozzle sandblast kūpono no kēlā me kēia noi he mea wale nō ia o ka hoʻomaopopo ʻana i nā ʻano like ʻole e pili ana i ka hoʻomaʻemaʻe ʻana a me nā koina hana. Inā ʻaʻole ʻoe maopopo i ke koho ʻana i kahi nozzle kūpono nou iho, e hahai i nā ʻanuʻu 4 e like me lalo.

1. E koho i ka Nozzle Bore Size

Ke koho ʻana i kahi nozzle, hoʻomaka ia me kāuea compressor. Ke hoʻomaopopo ʻoe i ka pili ʻana o ka nui o kāu compressor i nā mana hana, a laila makemake ʻoe e nānānui nozzle. E koho i kahi nozzle me ka liʻiliʻi loa o ka lua a e waiho ana ʻoe i kahi mana pahū ma ka papaʻaina. Nui loa ka lua a nele ʻoe i ke kaomi e pahū me ka huahua.

Hōʻike ka papa ma lalo nei i ka pilina ma waena o ka nui o ka ea, ka nui o ka nozzle, a me ke kaomi nozzle a hoʻohana pinepine ʻia i ka ʻoihana e koho i ka nui nozzle. ʻO kāna pōmaikaʻi maoli ke koho ʻana i ka nui nozzle maikaʻi loa no ke kaomi nozzle pono e hoʻokō i ka hana.

2. E koho i ka Nozzle Shape

Aʻe kake ano o ka nozzle. Loaʻa nā nozzles i ʻelua ʻano kumu:Sʻūhā pololeiaVenturi, me nā ʻano like ʻole o nā nozzles Venturi.

Nā nozzles Bore Pololei(Nā helu 1) hana i kahi ʻano hoʻoheheʻe paʻa no ka hana hoʻoheheʻe ʻana a i ʻole ka hana keʻena pahu. ʻOi aku ka maikaʻi o kēia no nā hana liʻiliʻi e like me ka hoʻomaʻemaʻe ʻana i nā ʻāpana, ka hana weld seam, hoʻomaʻemaʻe i nā lima lima, nā ʻanuʻu, grillwork, a i ʻole ke kālai pōhaku a me nā mea ʻē aʻe.

Hāʻawi ʻo Venturi i nā nozzles(Nā helu 2 a me 3) e hana i kahi ʻano pahū ākea a hoʻonui i ka wikiwiki abrasive e like me 100% no kahi kaomi i hāʻawi ʻia.

ʻO nā nozzles Venturi ke koho maikaʻi loa no ka hoʻonui ʻana i ka wā e puhi ana i nā ʻili nui. ʻO nā nozzle puʻu pālua a me nā nozzle puʻu ākea i hoʻonui ʻia o ka nozzle style venturi lōʻihi.

ʻO kapālua venturikaila (Helu 4) hiki ke noʻonoʻo ʻia he ʻelua nozzles i ka moʻo me kahi āpau a me nā lua ma waena e ʻae ai i ka hoʻokomo ʻana o ka ea i ka ʻāpana o lalo o ka nozzle. ʻOi aku ka laulā o ka hopena puka ma mua o ka nozzle maʻamau. Hana ʻia nā hoʻololi ʻelua i mea e hoʻonui ai i ka nui o ke ʻano pahū a hōʻemi i ka nalowale o ka wikiwiki abrasive.

Nā nozzle puʻu ākea(Helu 5) ka pu'u komo nui a me ka lua puka diverging nui. Ke hoʻohālikelike ʻia me ka hose like ʻole hiki iā lākou ke hāʻawi i kahi hoʻonui 15% o ka huahana ma luna o nā nozzles me kahi puʻu liʻiliʻi. He manaʻo maikaʻi nō hoʻi ka loaʻa ʻana o nā nozzles kihi no nā wahi paʻa e like me ka lattice wahine mare, ma hope o nā flanges, a i ʻole nā ​​paipu i loko. Nui nā mea hoʻohana i nā abrasives a me ka manawa e kali ana i ka ricochet e hoʻokō i ka hana. ʻO ka manawa liʻiliʻi e hoʻololi i kahinozzle kihiho'ōla koke 'ia, a ho'emi 'ia ka manawa ma ka hana.

3. E koho i ka Nozzle Material

Ke hoʻoholo ʻoe i ka nui a me ke ʻano o ka nozzle, makemake ʻoe e noʻonoʻo i kamea waiwaihana ʻia ka liner nozzle. ʻO nā kumu nui ʻekolu i ke koho ʻana i ka mea nozzle bore kūpono ʻo ka lōʻihi, ka hopena hopena, a me ke kumukūʻai.

ʻO ke koho ʻana i nā mea nozzle e pili ana i ka abrasive āu e koho ai, pehea ʻoe e puhi ai, ka nui o ka hana, a me nā koʻikoʻi o ka wahi hana. Eia nā alakaʻi hoʻohana maʻamau no nā mea like ʻole.

ʻO nā nozzles tungsten carbide:Hiki hāʻawi i ke ola lōʻihi a me ka hoʻokele waiwai inā ʻaʻole hiki ke pale ʻia ka hana ʻino. He kūpono no ka hoʻoheheʻe ʻana i ka slag, aniani, a me ka mineral abrasives.

Silicon carbidenā nozzles:Paʻa i ka hopena a 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 i ka wā lōʻihi nā mea hoʻohana a makemake i kahi nozzle māmā.

Nā nozzles Boron carbide:Paʻa loa a paʻa loa, akā palupalu. He mea kūpono ka Boron carbide no nā abrasive hoʻopaʻapaʻa e like me ka aluminika oxide a me nā hui mineral i koho ʻia ke pale ʻia ka hana ʻino. ʻOi aku ka maʻamau o ka carbide Boron ma mua 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. ʻO ke kumukūʻai ka mea kiʻekiʻe loa ma waena o lākou.

4. E koho i ka Uila a me ka Jacket

ʻO ka hope, pono ʻoe e koho i ke ʻano o ke kapa e pale ai i ka lua. Pono ʻoe e noʻonoʻo i ke ʻano o ka milo i kūpono i kāu mau pono sandblasting: milo maikaʻi a i ʻole milo coarse (contractor).

1) Kāleka Nozzle

ʻAʻahu Aluminum:Hāʻawi nā ʻaʻahu alumini i kahi kiʻekiʻe kiʻekiʻe o ka pale ʻana i ka pōʻino hopena i ka māmā.

Kāleka kila:Hāʻawi nā kapa kila i kahi kūlana kiʻekiʻe o ka pale ʻana i ka pōʻino o ka hopena i ke kaumaha kaumaha.

Kāleka Rubber:He māmā ke kapa Rubber oiai e hāʻawi mau ana i ka pale hopena.

2) 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.

Loiloi maikai(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 ʻĀkau.

NA MANAO HOPE

ʻO ka ea nui a me nā nozzles nui e alakaʻi i ka nui o ka hana ʻana, akā ʻo ke ʻano o ka pahu nozzle e hoʻoholo ai i ka wikiwiki o nā ʻāpana a me ka nui o ke kumu hoʻohū.

I nā mea a pau, ʻaʻohe nozzle maikaʻi loa, ʻo ka mea nui ke ʻimi i nā nozzles kūpono loa no kāu hoʻohana.
