Intshayelelo emfutshane yeVenturi Bore Nozzle

Kwinqaku lokugqibela, sathetha nge-nozzle bore ngqo. Kweli nqaku, i-Venturi bore nozzles iya kwaziswa.

Imbali

Ukujonga kwimbali yeVenturi bore nozzle, konke kwaqala ngo-1728. Kulo nyaka, ingcali yezibalo yaseSwitzerland kunye nefiziksi uDaniel Bernoulli upapashe incwadi egama linguDaniel Bernoulli.I-Hydrodynamic. Kule ncwadi, wachaza ukufumanisa ukuba ukuncipha koxinzelelo lwe-fluid kuya kubangela ukwanda kwesantya samanzi, okubizwa ngokuba yi-Bernoulli's Principle. Ngokusekwe kuMgaqo kaBernoulli, abantu benza iimvavanyo ezininzi. Kude kube ngoo-1700, ingcali yefiziksi yase-Italiya u-Giovanni Battista Venturi yaseka i-Venturi Effect---xa ulwelo luhamba ngecandelo elicuthekileyo lombhobho, uxinzelelo lolwelo luya kuncipha. Emva kwexesha iVenturi yazala imilomo yaqanjwa ngokusekwe kule ithiyori ngeminyaka yoo-1950. Emva kweminyaka emininzi besebenzisa, abantu bayaqhubeka nokuhlaziya iVenturi bore nozzle ukuze ilingane nophuhliso lweshishini. Namhlanje, i-Venturi bore nozzles isetyenziswa kakhulu kwishishini langoku.

Ulwakhiwo

I-Venturi bore nozzle yadityaniswa kunye nesiphelo esiguqukayo, icandelo elithe tye elithe tye, kunye nesiphelo esingafaniyo. Umoya owenziweyo uqukuqela ukuya kwisiguquli ngesantya esiphezulu kuqala uze udlule kwindawo emfutshane ethe nkqo ethe tyaba. Ngokwahlukileyo kwimilomo ebhobhozayo ethe tye, imilomo yeVenturi inecandelo elahlukileyo, elinokunceda ukuthoba imilomo.i-vertexumsebenzi ukuze ulwelo lomoya lukhutshwe ngesantya esiphezulu. Isantya esiphezulu sinokwenza ukusebenza okuphezulu kokusebenza kunye nezixhobo ezinqabileyo. I-Venturi ibhore imilomo ilungele imveliso enkulu ngexesha loqhushumbo ngenxa yemveliso yazo yokuqhushumba kunye nesantya esirhabaxa. Imilomo ebolileyo yeVenturi inokuvelisa ukwabiwa kwamasuntswana afanayo, ngoko ke ikulungele ukuqhushumba imiphezulu emikhulu.

Izinto eziluncedo kunye nezingeloncedo

Njengoko besithethile ngaphambili, iVenturi bore imilomo inokunciphai-vertexumsebenzi. Ke baya kuba nesantya esiphezulu solwelo lomoya kwaye banokusebenzisa izinto ezirhabaxa kancinci. Kwaye baya kuba nemveliso ephezulu, emalunga ne-40% ephezulu kunombhobho othe ngqo.

Isicelo

Imilomo yeVenturi ihlala ibonelela ngemveliso ephezulu xa kuqhunyiswa imiphezulu emikhulu. Ngenxa yemveliso yabo ephezulu, banokuqonda ukuqhushumba komphezulu ekunzima kakhulu ukuwenza.

Ukuba ufuna ukufunda ngakumbi malunga nokuqhushumba kwe-abrasive, wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe vetshe.
