Isingeniso esifushane se-Venturi Bore Nozzle

Esihlokweni sokugcina, sikhulume ngombhobho oqondile. Kulesi sihloko, kuzokwethulwa imibhobho ye-Venturi bore.

Umlando

Ukubheka emlandweni we-Venturi bore nozzle, konke kwaqala ngo-1728. Kulo nyaka, isazi sezibalo saseSwitzerland uDaniel Bernoulli washicilela incwadi ebizwa ngokuthi.I-Hydrodynamic. Kule ncwadi, uchaze ukutholakala kokuthi ukwehla kokucindezela koketshezi kuzoholela ekwandeni kwesivinini samanzi, okubizwa ngokuthi I-Bernoulli's Principle. Ngokusekelwe kuSimiso sikaBernoulli, abantu benza izivivinyo eziningi. Kuze kube ngama-1700s, isazi sefiziksi sase-Italy u-Giovanni Battista Venturi sasungula i-Venturi Effect---lapho uketshezi lugeleza engxenyeni eboshiwe yepayipi, ukucindezela koketshezi kuzokwehla. Kamuva ama-Venturi abhoboza ama-nozzle asungulwa ngokususelwa kulo mbono ngeminyaka yawo-1950. Ngemuva kweminyaka eminingana besebenzisa, abantu bayaqhubeka nokuvuselela i-Venturi bore nozzle ukuze ilingane nokuthuthukiswa kwemboni. Namuhla, i-Venturi bore nozzles isetshenziswa kabanzi embonini yesimanje.

Isakhiwo

I-Venturi bore nozzle yahlanganiswa nesiphetho esiguquguqukayo, ingxenye eqondile eyisicaba, kanye nesiphetho esihlukanisiwe. Umoya okhiqiziwe ugeleza uye ku-converging ngesivinini esikhulu kuqala bese udlula esigabeni esifushane esiyisicaba esiqondile. Ihlukile emibhobolweni ebhobozayo eqondile, imilomo ye-Venturi inengxenye ehlukene, engasiza ekunciphisenii-vertexumsebenzi ukuze uketshezi lomoya lukhishwe ngesivinini esiphezulu. Isivinini esiphezulu singenza ukusebenza kahle okuphezulu kanye nezinto ezincipha kakhulu. I-Venturi bore nozzles ilungele ukukhiqiza okukhulu ngesikhathi sokuqhuma ngenxa yokukhiqiza kwayo kokuqhuma kanye nesivinini esibi. I-Venturi bore nozzles ingaphinda ikhiqize ukusabalalisa kwezinhlayiyana okufanayo, ngakho-ke alungele ukuqhuma izindawo ezinkulu.

Izinzuzo Nokubi

Njengoba sike sakhuluma ngaphambili, i-Venturi bore nozzles inganciphisai-vertexumsebenzi. Ngakho-ke azoba nesivinini esiphezulu soketshezi oluvunguzayo futhi angadla izinto eziqhuma kancane. Futhi bazoba nokukhiqiza okuphezulu, okucishe kube ngama-40% aphezulu kunombobo oqondile.

Isicelo

Ama-nozzle e-Venturi ngokuvamile ahlinzeka ngokukhiqiza okuphezulu lapho kuqhunyiswa izindawo ezinkulu. Ngenxa yokukhiqiza kwabo okuphezulu, bangakwazi futhi ukubona ukuqhumisa izindawo okunzima kakhulu ukuzikhiqiza.

Uma ufuna ukufunda kabanzi mayelana nokuqhunyiswa kwe-abrasive, wamukelekile ukuthi usithinte ukuze uthole ulwazi olwengeziwe.
