Sumo pfupi yeVenturi Bore Nozzle

Muchinyorwa chekupedzisira, takataura nezve yakatwasuka bore nozzle. Muchikamu chino, iyo Venturi yakaboora nozzles ichaunzwa.

Nhoroondo

Kutarisa munhoroondo yeVenturi yakaboora nozzle, zvese zvakatanga muna 1728. Gore rino, nyanzvi yemasvomhu yekuSwitzerland uye nyanzvi yefizikisi Daniel Bernoulli akabudisa bhuku rainzi.Hydrodynamic. Mubhuku rino, akatsanangura kuwanikwa kwekuti kuderera kwekumanikidzwa kwemvura kuchaita kuti kuwedzera kwevelocity velocity, iyo inonzi Bernoulli's Principle. Kubva paMutemo waBernoulli, vanhu vakaita zvakawanda zvekuedza. Kusvika kuma1700s, nyanzvi yefizikisi yekuItaly Giovanni Battista Venturi akatanga Venturi Effect---kana mvura ichiyerera nepachikamu chakavharwa chepombi, kudzvanywa kwemvura kunoderera. Gare gare Venturi yakabereka nozzles yakagadzirwa zvichienderana nedzidziso iyi muma1950s. Mushure memakore akati wandei vachishandisa, vanhu vanoramba vachivandudza iyo Venturi bore nozzle kuti ikwane kusimudzira indasitiri. Mazuva ano, iyo Venturi yakabereka nozzles inoshandiswa zvakanyanya muindasitiri yemazuva ano.

Chimiro

A Venturi bore nozzle yakasanganiswa neinotenderera yekupedzisira, iyo flat yakatwasuka chikamu, uye magumo akasiyana. Mhepo inogadzirwa inoyerera ichienda kune inoshanduka nekumhanya kukuru kutanga uye yobva yapfuura nepakati pechikamu chipfupi chakatwasuka. Yakasiyana kubva kumawere akatwasuka, Venturi bore nozzles ine chikamu chakasiyana, chinogona kubatsira kuderedzavertexbasa kuitira kuti mvura yemhepo isunungurwe nekumhanya kwakanyanya. Iyo yakakwirira velocity inogona kuita iyo yepamusoro yekushanda inoshanda uye isinganyanye abrasive zvinhu. Venturi yakaboora nozzles yakanakira kubereka kukuru panguva yekuputika nekuda kwekuputika kwayo kubereka uye abrasive velocity. Venturi bore nozzles inogona zvakare kuburitsa yakawedzera yunifomu particle kugovera, saka inokodzera kuputika nzvimbo dzakakura.

Zvakanakira & Zvakaipa

Sezvatakambotaura nezvazvo, iyo Venturi yakabereka nozzles inogona kuderedza iyovertexbasa. Saka vanozove nevelocity yakakwira yemhepo yemhepo uye vanogona kushandisa zvinhu zvisinganyanyi kukuvadza. Uye ivo vachave nemhando yepamusoro, iyo inenge 40% yakakwirira kupfuura yakatwasuka bore nozzle.

Application

Venturi yakaboora nozzles kazhinji inopa kugadzirwa kwepamusoro kana ichiputika nzvimbo dzakakura. Nekuda kwekuita kwavo kwepamusoro, vanogona zvakare kuona kuputika kwepasi izvo zvakanyanya kuoma kugadzira.

Kana iwe uchida kudzidza zvakawanda nezve abrasive blasting, unogamuchirwa kuti ubate isu kuti uwane rumwe ruzivo.
