二: Umgomo osebenzayo we-tube ye-venturi
I-Venturi yithuluzi lokuthola i-vacuum elisebenzisa uketshezi lokudlulisa amandla nobunzima. Isakhiwo saso esivamile sikhonjiswa kuMdwebo 1. Kuqukethe i-nozzle esebenzayo, indawo yokumisa, umphimbo wokuxuba, umphimbo kanye ne-diffuser. Kuyinto generator ye-vacuum. Ingxenye esemqoka yedivayisi iyinto entsha, esebenza kahle, ehlanzekile futhi enobuhlakani ye-vacuum esebenzisa umthombo wamanzi omuhle wokukhiqiza ingcindezi engemihle. Inqubo esebenzayo yokuthola i-vacuum inje:
I-01, isigaba esivela ePoint 1 to Point 3 yisigaba sokusheshisa soketshezi olunamandla ku-nozzle. I-fluid ephakeme yengcindezelo yengcindezelo ifaka i-nozzle esebenzayo ye-venturi e-velocity ephansi engxenyeni ye-nozzle inlet (point 1 isigaba). Lapho ugeleza esigabeni se-tapered of the nozzle esisebenzayo (isigaba 1 kuya kwesigaba 2), kungaziwa kusuka ku-fluid mechanics ukuthi, ngokuqhubeka kokugeleza kwengxenye ye-Q2 ye-Q1 yofuba i-Q1 = Q2,
Scilicet A1v1 = A2VV2
Efomula, a1, A2 - indawo yesigaba sendawo yendawo 1 nephuzu 2 (m2);
v1, v2 - I-fluid velocity igeleza ngePoint 1 isigaba kanye nePhoyinti 2 Isigaba, M / s.
Kungabonakala kusuka kwifomula engenhla ukuthi ukukhuphuka kwesigaba sesiphambano, ukugeleza kwe-flow velocity kuyancipha; Ukuncishiswa kwesigaba sesiphambano, ukugeleza kwe-flow velocity.
Kumapayipi avundlile, ngokusho kwe-bernoulli's equation yoketshezi olungaguquki
P1+ (1/2) * ρv12=P2+ (1/2) ρv22
Efomula, P1, P2 - ingcindezi ehambisanayo engxenyeni yesiphambano sephuzu 1 nephuzu 2 (PA)
v1, v2 - velocity (m / s) egeleza esigabeni ngephuzu 1 nephuzu 2
ρ - Ubuningi bukaketshezi (kg / m³)
Kungabonakala kwifomula engenhla yokuthi ukugeleza kwe-velocity ye-flow yoketshezi olunamandla kukhuphuka ngokuqhubekayo futhi ingcindezi iyancipha ngokuqhubekayo kusuka ePhoyinti 1 Isigaba esiseqophelweni esingu-1. Lapho v2> v1, p1> p2, lapho i-v2 inyuka ngenani elithile (ingafinyelela ijubane lomsindo), i-P2 izokwenziwa ngaphansi kwengcindezi eyodwa yomoya, okungukuthi, ingcindezi engemihle izokhiqizwa esigabeni se-point 3.
Lapho uketshezi lwe-tutive lungena engxenyeni yokwanda kwe-nozzle yokusebenza, okungukuthi, isigaba esivela ePhoyinti 2 kuya esigabeni esisesigabeni 3, isivinini soketshezi lwe-motive qhubeka. Lapho uketshezi olunamandla lufinyelela engxenyeni yokuphuma engxenyeni yokusebenza ye-nozzle (isigaba se-point 3), isivinini soketshezi esishukumisayo sifinyelela phezulu futhi singafinyelela isivinini esinamandla. Ngalesi sikhathi, ingcindezi engxenyeni ePoint 3 ifinyelela ubuncane, okungukuthi, i-vacuum degree ifinyelela phezulu, ongafinyelela ku-90kpa.
02., isigaba esivela ePoint 3 ukuze sikhombe u-5 isiteji sokuxuba uketshezi lwe-motive kanye noketshezi olunamapule.
Uketshezi olusheshisa kakhulu olusungulwe yi-fluid enamandla engxenyeni yokuphuma kwe-nozzle (isigaba 3) izokwakha indawo ye-cang egumbini lokuxuba. Uketshezi olugcwele lungeniswe egumbini lokuxuba ePhoyinti lePhoyinti. Ngesikhathi sokugeleza kusuka esigabeni sePhoyinti 9 kuya esigabeni esingu-5, ijubane loketshezi olugcwele lukhuphuka ngokuqhubekayo, futhi ingcindezi iyaqhubeka yehla emandleni engxenyeni engu-13 isigaba esigabeni esingu-13. Ingcindezi yoketshezi engxenyeni yokuphuma kwe-nozzle (point 3).
Esigabeni segumbi lokuxuba kanye nengxenye yangaphambili yomphimbo (isigaba esivela ePoint 3 ukuze sikhombe 6) I-Fluid, ukuze i-velocity yofuba oshukumisayo kancane kancane incipha, ukuvezwa komzimba okumunca kancane kancane, futhi ama-velocities amabili ancipha kancane kancane futhi asondele. Ekugcineni, esigabeni esingu-4, ijubane ezimbili zifinyelela ngejubane elifanayo, futhi umphimbo kanye ne-diffuser ye-venturi ayakhishwa.
