I-Venturi Nozzle Yezibhamu Zomoya

Umbhobho we-venturi wezibhamu zomoya uhlanganisa ishubhu elide, elimise okwesilinda elinendawo ephumayo ekhawulelwe emoyeni ocindezelweyo owamukela ukuphela kwawo lapho umoya ocindezelwe udluliselwa ekugcineni kwawo. Indawo yokugeleza komoya yokuphela kokukhishwa kweshubhu inkulu kunendawo yokugeleza komoya ye-orifice ukuvumela ukunwetshwa komoya ophuma emgodini endaweni yokuphela kokukhishwa kweshubhu eliseduze ne-orifice. Izimbobo ezakhiwe ngeshubhu ekugcineni kwalo okuphumayo eduze kwe-orifice zivumela umoya ozungezile ukuba udonswe umphumela we-venturi ungene eshubhuni futhi ukhishwe ngomoya owandisiwe ophuma ekugcineni kweshubhu. Kutholwe ukuthi lapho izimbobo zimi eduze komjikelezo weshubhu ezindaweni ezingaphikiswani ne-ametric, futhi inobude eduze kwe-eksisi yeshubhu enkulu kunobubanzi bezikhala ezizungeze isiyingi seshubhu, ivolumu umoya ophumayo ophuma ekugcineni kombhobho ukhuliswa ngevolumu enikeziwe yokufakwa komoya ocindezelwe ekupheleni kokwamukela umlomo wombhobho. Ngaphezu kwalokho, kuphinde kwatholakala ukuthi lapho iziphetho zezikhala ngobude bazo zicindezelwe nge-engeli ebukhali ngokuhlobene ne-eksisi yeshubhu ngasekugcineni kokwamukela, umthamo wokukhipha komoya ophuma ekugcineni kombhobho ithuthukiswa futhi nomsindo odalwa umoya odlula ku-nozzle uyancishiswa.

1. Inkambu

Iphaseji ihlobene nemibhobho yezibhamu zomoya, futhi ikakhulukazi umlomo wombhobho we-venturi wesibhamu somoya esikhulisa ivolumu yomoya ophuma emlonyeni wevolumu enikeziwe yokufaka umoya ocindezelwe lapho, futhi enciphisa umsindo okhiqizwa umlomo wombhobho phezu kwawo. ukudlula komoya lapho.

2. Incazelo Yobuciko Bangaphambili

Ekwakhiweni nasekugcinweni kwezinhlobo ezahlukene zemishini, izibhamu zomoya zivame ukuqashwa ukuze kuqhunyiswe uthuli nezinye izinsalela zemishini. Izibhamu zomoya ngokuvamile zisebenza ngomfutho womoya wokufaka omkhulu kuno-40 psi. Nokho, ngenxa yezinga elilodwa elimenyezelwe ngaphansi kwe-Occupational Safety and Health Act (OSHA), ingcindezi ephezulu ekhiqizwa ithiphu yokukhipha umlomo wesibhamu somoya lapho umlomo wesibhamu ufile, njengokubekwa ngokumelene nesandla somsebenzisi noma iflethi. ubuso, kufanele bube ngaphansi kwama-psi angama-30.

Umbhobho owaziwayo wokudambisa inkinga yokwakhiwa kwengcindezi ephelile uhlanganisa imbobo ekhawulelwe ngaphakathi kwebhobo emaphakathi yomlomo lapho umoya ocindezelwe udlula khona ekugcineni kombhobho., kanye nobuningi bezikhala eziyindilinga ezakheke ngombhobho ekugcineni kwawo. Uma ukuphela kokukhishwa kombhobho sekuphelile, umoya ocindezelwe phakathi kwawo udlula ezimbotsheni eziyindilinga, noma imigodi yokukhipha umoya, ukuze ukhawulele ukunqwabelana kwengcindezi ngaphakathi komkhawulo wokuphuma wombhobho.

Ngaphezu kwalokho, ezimweni eziningi, ama-compressor atholakalayo ukuze anikeze umoya ocindezelwe ezibhamuni alinganiselwe ngomthamo, okuholela ekungakwazini ukunikeza umoya ngokuqhubekayo kunoma yisiphi isibhamu somoya esisodwa, noma ekungakwazini ukusebenzisa ngesikhathi esisodwa izibhamu zomoya ezimbalwa. Ngenkathi imibhobho ye-venturi yangaphambilini isebenze ukukhulisa umthamo womoya ophuma embotsheni yokukhipha kagesi yembobo yevolumu enikeziwe yokufakwa komoya ocindezelwe embhobhweni osuka kusibhamu somoya, ukwanda okutholiwe akubanga ubukhulu obanele ukuze kuvumeleke ukwaneliseka nokusebenza kahle. ukusetshenziswa kwama-compressor umthamo olinganiselwe. Ngakho-ke, kuyafiseleka ukuthi idizayini yombhobho ophumayo ibe njengokukhulisa umthamo womoya ophuma kuwo ngevolumu enikeziwe yokufaka umoya ocindezelwe lapho.

ISIFINYEZO

Ngokuvumelana nokusunguliwe kwamanje, umlomo wombhobho okhipha uketshezi lwe-venturi uhlanganisa ishubhu elide, elimise okwesilinda elinembobo ekhawulelwe eyakhiwe eduze nendawo ethola uketshezi lapho uketshezi lwegesi olucindezelwe ludlulela ekugcineni koketshezi oluphumayo. Indawo yokugeleza koketshezi ekugcineni kokuphuma kweshubhu inkulu kunendawo egeleza uketshezi ye-orifice ukuvumela ukunwetshwa koketshezi oludlula emgodini endaweni yokuphela kokuphuma kweshubhu eseduze nomgudu, kanye nobuningi be-nondiametrically. izimbobo ezinde eziphikisiwe (okungukuthi, izimbobo eziningi ezinobude obuhambisana ne-eksisi yeshubhu elikhulu kunobubanzi bembobo eduze komjikelezo weshubhu) kwakheka ngeshubhu ngobude balo ukusuka endaweni eseduze neshubhu. imbobo ekhawulelwe ukuya endaweni ebheke ekugcineni okuphumayo kweshubhu ukuze kuvunyelwe uketshezi lwegesi oluzungezile eduze nengaphandle leshubhu ukuthi ludonswe umphumela we-venturi ngembobo eshubhu futhi lukhishwe ngoketshezi olunwetshiwe oluphuma ekugcineni kweshubhu.

Ngokukhethekile, izimbobo ezinde ezintathu zakheka ngeshubhu ekukhuphukeni okungu-120° endaweni ezungezile yeshubhu okuyiqiniso okuyishubhu le-venturi elichazwa yipheya lezindawo ezicijile zangaphakathi ezineziphetho zazo ezincane ezihlanganiswe yisilinda esifushane noma umphimbo we-venturi. . Izimbobo ezinde zitholakala eduze komkhawulo wokuphuma komphimbo we-venturi futhi zidlulele ezindaweni ezisikiwe ohlangothini lokuphuma komphimbo. Zombili izindawo zokugcina ziboshwe ngendlela efanayo ukuze zinwebeke ukusuka endaweni yangaphakathi yeshubhu kubuyele ekugcineni kweshubhu.

Imbobo yokukhipha yalokhu okusunguliwe ifaneleka ngokukhethekile ukusetshenziswa kusistimu yokukhipha igesi enomthombo wamandla alinganiselwe, isb., i-compressor yomoya ephathekayo, ngenxa yeqiniso lokuthi umlomo wombhobho ukhuphula kakhulu umthamo wokukhipha komoya kuvolumu ethile okokufaka komoya okucindezelwe ku-nozzle ngokuhlobene nemibhobho yangaphambili enezimbobo eziyindilinga lapho.
