Kaviri Venturi Kuputika Nozzles 

Blasting Nozzles kazhinji inouya mumhando mbiri: straight bore uye venturi, ine misiyano yakati wandei ye venturi nozzles.

Venturi nozzles anowanzo kukamurwa kuita single-inlet venturi uye kaviri-inlet venturi nozzle.

Iyo imwechete venturi nozzle ndeye yakajairika venturi nozzle. Yakagadzirwa mune yakareba tapered converging yekupinda, ine kapfupi sandara yakatwasuka chikamu, ichiteverwa neinorebesa magumo ayo anozowedzera paunosvika kumagumo emuromo. Chimiro ichi chakagadzirirwa kuburitsa mhedzisiro inomhanyisa zvakanyanya mafambiro emhepo uye zvimedu uye zvakaenzana kugovera abrasive pamusoro peiyo blast pattern, ichibereka inenge 40% yakakura chiyero chekugadzira pane yakatwasuka bore nozzle.

Iyo double venturi nozzle inogona kufungidzirwa semapfumbu maviri akatevedzana ane gap nemaburi pakati kuti abvumire kuiswa kwemweya wemuchadenga muchikamu chepasi pemvura. Iyo yekubuda inopera zvakare yakakura kupfuura yakajairwa venture blast nozzle. Kaviri venturi nozzles inopa yakatenderedza 35% yakakura kuputika pateni pane yakajairwa venturi blast nozzle inongorasikirwa zvishoma muabrasive velocity. Nekupa yakakura kuputika pateni, iyo abrasive blast nozzle inogonesa kuwedzera abrasive kuputika kunyatsoshanda. Yakanakira mabasa panodiwa kuputika kwakakura.

MuBSTEC, unogona kuwana akawanda marudzi emaviri venturi nozzles.

1.     Yakarongwa neNozzle Liner Material

• Silicon Carbide Double Venturi Nozzle:hupenyu hwesevhisi uye kusimba kwakafanana netungsten carbide, asi chikamu chimwe chete muzvitatu chehuremu hwetungsten carbide nozzles. Silicon carbide nozzles isarudzo yakanakisa kana vashandisi vari pabasa kwenguva yakareba uye vachifarira mitsipa isingaremi.

• Boron Carbide Double Venturi Nozzle:chinhu chinogara kwenguva refu chinoshandiswa pakuputitsa nozzles. Inopfeka tungsten carbide kashanu kusvika kagumi uye silicon carbide kaviri kana katatu kana mabrasives ane hukasha ashandiswa. Boron carbide nozzle yakanakira mabrasives ane hukasha senge aluminium oxide uye akasarudzwa mamineral aggregates kana kubata kwakashata kuchigona kudzivirirwa.

2.    Classified by Thread Type

• Coarse (Contractor) Thread:Indasitiri-yakajairwa shinda pa 4½ shinda pa inch (TPI) (114mm), chimiro ichi chinodzikisira zvakanyanya mukana wekuyambuka-shinda uye iri nyore kuisa.

• Fine Thread(NPSM Thread): The National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) ndiyo Indasitiri mwero wakatwasuka shinda inoshandiswa zvakanyanya muNorth America.

3.    Yakakamurwa neNozzle Jacket

• Aluminium Jacket:ipa yakanyanya mwero wedziviriro kubva mukukanganisa kukuvara mune lightweight.

• Simbi Jacket:ipa yakanyanya mwero wedziviriro kubva mukukanganisa kukuvara muheavyweight.
