Venturi Nozzle yeMhepo Pfuti

Iyo venturi nozzle yepfuti dzemhepo inosanganisira yakareba, cylindrical shaped chubhu ine muromo wakaganhurirwa mumhepo yakadzvanyirirwa inogashira magumo ayo iyo mweya wakadzvanywa unopfuudzwa kumagumo ayo. Nzvimbo yekuyerera kwemhepo yekuguma kwekubuda kwechubhu yakakura kudarika nzvimbo yekuyerera kwemhepo ye orifice kubvumira kuwedzera kwemhepo inobuda muhombe munharaunda yekuguma kwekubuda kwechubhu iri pedyo neorifice. Matunhu akaumbwa kuburikidza nechubhu iri mumagumo ekuyerera ayo akatarisana neorifice anobvumira mweya wepamhepo kuti udhorwe ne venturi effect muchubhu uye kuti ubudiswe nemhepo yakawedzerwa kunze kwekubuda kwechubhu. Zvakaonekwa kuti kana maapertures akamira akatenderedza denderedzwa rechubhu panzvimbo dzisingapikiswe, uye aine kureba pamwe neaxis yechubhu iyo yakakura kudarika hupamhi hwemaapertures akatenderedza denderedzwa rechubhu, vhoriyamu mhepo inobuda kubva kumagumo ekuyerera kwemhuno inokwidziridzwa kune yakapihwa vhoriyamu yemhepo yakadzvanywa yekupinda kusvika kumagumo ekugamuchira emhuno. Uyezve, zvakaonekwa zvakare kuti kana migumo yezvivharo pamwe nekureba kwayo yakanyungudutswa paacute angle inoenderana neaxis yechubhu yakananga kumagumo ekugamuchira kwayo, huwandu hwemhepo inobuda kubva kumagumo ekubuda kwemuromo. kuwedzera uye ruzha rwunogadzirwa nemhepo inopfuura nemumuromo unodzikiswa.

Mukugadzira nekuchengetedza mhando dzakasiyana dzemidziyo, pfuti dzemhepo dzinowanzo shandiswa kupfutidza huruva uye mamwe marara kubva mumidziyo. Pfuti dzemhepo dzinowanzoshanda nemhepo inopinza inodarika 40 psi. Nekudaro, semhedzisiro yeimwe chiyero chakaburitswa pasi peOccupational Safety and Health Act (OSHA), iyo yakanyanya kudzvanywa inogadzirwa pamhepo pfuti inoburitsa muromo kana muromo wapera, sekunge nekuiswa paruoko rwemushandisi kana furati. pamusoro, inofanira kuva isingasviki makumi matatu psi.

Mupfumo unozivikanwa wekudzikisa dambudziko rekufa kwakapera kumanikidza kuvakwa kunosanganisira muromo wakaganhurirwa mukati memuboora wepakati pemhuno umo mweya wakadzvanyirirwa unopinda panoperera muromo., uye kuwanda kwe denderedzwa apertures akaumbwa kuburikidza nemuromo painobuda kupera kwayo. Kana panobuda muromo wemuromo wapera, mweya wakatsikirirwa urimo unopfuura nemumaburi edenderedzwa, kana maburi emhepo, kudzikamisa kuvakwa kwekumanikidza mukati mekupera kwekubuda kwemuromo.

Uyezve, muzviitiko zvakawanda, macompressor aripo ekupa mweya wakamanikidzwa kupfuti ane mashoma mukukwanisa, zvichikonzera kutadza kugovera mweya nguva dzose kune chero pfuti yemhepo, kana kusakwanisa kushandisa panguva imwe chete pfuti dzemhepo dzinoverengeka. Nepo yapfuura ma venturi nozzles akashanda kuwedzera huwandu hwemhepo inoburitswa kubva mugomba rekuburitsa remuromo kune yakapihwa vhoriyamu yekumanikidzwa kwemhepo kupinza kumuromo kubva mupfuti yemhepo, kuwedzera kwakawanikwa kwave kusati kwave kwehukuru hwakakwana kubvumidza inogutsa uye inoshanda. kushandiswa kwema compressor mashoma. Naizvozvo, zvinoshuviwa kuti dhizaini yemuromo unobuda mhepo ive yakaita sekuwedzera huwandu hwemhepo inoburitswa kubva mairi kune yakapihwa vhoriyamu yekudzvanywa kwemhepo inopinza ipapo.

SUMMARY

Zvinoenderana nekugadzirwa kwazvino, venturi fluid discharge nozzle inosanganisira yakareba, cylindrical shaped chubhu ine inovharika orifice inoumbwa padyo nemvura inogashira magumo ayo kuburikidza neyakamanikidzwa gaseous fluid inopfuudzwa muinobuda mvura inopera. Nzvimbo yemvura inoyerera yekupera kwekubuda kwechubhu yakakura kudarika nzvimbo yemvura inoyerera ye orifice kubvumira kuwedzera kwemvura yakapfuura nepakati munharaunda yekuguma kwekubuda kwechubhu iri pedyo nehove, uye kuwanda kwenondiametrically. maburi akareba anopikisa (kureva, kuwanda kwemaburi ega ega ane kureba achitevedza akiso yechubhu iyo yakakura kudarika upamhi hwepaburi ichitevedza denderedzwa rechubhu) inoumbwa nemuchubhu pakureba kwayo kubva panzvimbo iri padyo inoganhurirwa muromo kusvika painoperera kumagumo kwechubhu kubvumira ambient gaseous fluid iri padyo nekunze kwechubhu kuti idhonzwe neventuri effect kuburikidza neaperture ichipinda muchubhu uye inobuditswa nemvura yakawedzerwa kunze kwekubuda kunopera kwechubhu.

Zvikuru, maburi matatu akarebesa anoumbwa kuburikidza nechubhu iri pa120 ° increments yakatenderedza periphery yechubhu inova iyo chaiyo venturi chubhu inotsanangurwa nembiri yemukati truncated conical surfaces ine magumo madiki akabatanidzwa nepfupi cylindrical pamusoro kana venturi huro. . The elongated apertures anowanikwa padyo nekubuda kunopera kwe venturi huro uye anotambanukira mukati me truncated surfaces padivi rekubuda pahuro. Mamiriro ese ari maviri ekupedzisira akatemerwa munzira imwechete kuti awedzere kubva mukati mechubhu achidzokera kumucheto wekugamuchira wechubhu.

Iyo inoburitsa muromo yeichi chigadzirwa inonyanya kukodzera kushandiswa mugasi rekuburitsa sisitimu ine sosi yehushoma kugona, semuenzaniso, inotakurika air compressor, tichifunga kuti iyo muromo inowedzera zvakanyanya huwandu hwekubuda kwemhepo kune yakapihwa vhoriyamu. kupinza mweya wakadzvanyirirwa kumuromo unoenderana nemapfumbu ekare ane denderedzwa apertures imomo.
