Sehloohong se fetileng, re buile ka nozzle e otlolohileng. Sehloohong sena, ho tla hlahisoa li-nozzles tsa Venturi.

 

Histori

Ho sheba historing ea Venturi bore nozzle, tsohle li qalile ka 1728. Selemong sena, setsebi sa lipalo le fisiks sa Switzerland Daniel Bernoulli o ile a hatisa buka e bitsoang.Hydrodynamic. Bukeng ena, o hlalositse ho sibolloa hore ho fokotseha ha khatello ea mokelikeli ho tla lebisa ho eketseha ha lebelo la mokelikeli, le bitsoang Molao-motheo oa Bernoulli. Ho latela Molao-motheo oa Bernoulli, batho ba ile ba etsa liteko tse ngata. Ho fihlela lilemong tsa bo-1700, setsebi sa fisiks sa Motaliana Giovanni Battista Venturi se thehile Venturi Effect---ha mokelikeli o phalla karolong e patehileng ea phala, khatello ea mokelikeli e tla fokotseha. Hamorao Venturi bore nozzles li ile tsa qaptjoa ho latela khopolo ena lilemong tsa bo-1950. Kamora lilemo tse 'maloa ba sebelisa, batho ba ntse ba tsoela pele ho nchafatsa Venturi bore nozzle hore e lekane nts'etsopele ea indasteri. Matsatsing ana, li-nozzles tsa Venturi li sebelisoa haholo indastering ea sejoale-joale.

 

Sebopeho

Nozzle ea Venturi e ne e kopantsoe le pheletso e kopaneng, karolo e otlolohileng e bataletseng, le pheletso e fapaneng. Moea o hlahisoang o phallela ho convergent ka lebelo le phahameng pele ebe o feta karolong e khutšoanyane e otlolohileng e bataletseng. Ho fapana le li-nozzles tse otlolohileng, li-nozzles tsa Venturi li na le karolo e fapaneng, e ka thusang ho fokotsavertextshebetso e le hore lero la moya le tle le lokolloe ka lebelo le phahameng. Lebelo le phahameng le ka etsa hore ts'ebetso e sebetse hantle le lisebelisoa tse fokolang haholo. Li-nozzles tsa Venturi li loketse tlhahiso e kholo nakong ea ho qhomisoa ka lebaka la tlhahiso ea tsona ea ho phatloha le lebelo le leholo. Li-nozzles tsa Venturi le tsona li ka hlahisa kabo e tšoanang ea likaroloana, kahoo li loketse ho phatloha libakeng tse kholoanyane.

Melemo & Mefokolo

Joalo ka ha re buile pele, li-nozzles tsa Venturi li ka fokotsavertextshebetso. Kahoo li tla ba le lebelo le holimo la mokelikeli oa moea 'me li ka sebelisa lisebelisoa tse fokolang haholo. 'Me ba tla ba le tlhahiso e phahameng, e ka bang 40% e phahameng ho feta nozzle ea bore e otlolohileng.

 

Kopo

Li-nozzles tsa Venturi hangata li fana ka tlhahiso e phahameng ha ho phatloha libaka tse kholoanyane. Ka lebaka la tlhahiso ea bona e phahameng, ba ka boela ba hlokomela ho phatloha ha libaka tseo ho leng thata ho li etsa.

 

Haeba u batla ho ithuta haholoanyane ka abrasive blasting, amohela ho ikopanya le rona bakeng sa lintlha tse ling.
