Fa'idodin injin turbin kwararar axial
Idan aka kwatanta da turbines na Francis, turbines na kwararar axial suna da manyan fa'idodi masu zuwa:
1. Babban gudu na musamman da kyawawan halaye na makamashi. Saboda haka, saurin na'urarsa da kwararar na'urar sun fi na injin Francis turbine. A ƙarƙashin yanayin ruwa iri ɗaya da fitarwa, yana iya rage girman na'urar samar da injin turbine sosai, rage nauyin na'urar, da kuma adana amfani da kayan aiki, don haka yana da tsada.
2. Siffar saman da kuma kauri na ruwan wukake mai gudu na injin turbin kwararar axial zai iya cika buƙatun masana'anta cikin sauƙi. Saboda ruwan wukake na injin turbin juyawa na axial-flow na iya juyawa, matsakaicin inganci ya fi na injin turbin haɗuwa. Lokacin da nauyin kaya da kan ruwa suka canza, ingancin ba ya canzawa sosai.
3. Za a iya wargaza ruwan wukake masu gudu na injin turbin paddle-flow, wanda ya dace da ƙera da jigilar su.
Saboda haka, injin turbin kwararar axial zai iya kiyaye kwanciyar hankali a cikin babban kewayon aiki, tare da ƙarancin girgiza, da ingantaccen aiki da fitarwa. A cikin kewayon ƙananan kai, ya kusan maye gurbin injin turbin Francis. A cikin 'yan shekarun nan, duka dangane da ƙarfin naúrar guda ɗaya da amfani da kan ruwa, an sami babban ci gaba, kuma aikace-aikacensa ma yana da faɗi sosai.
Rashin amfani da injin turbin kwararar axial
Duk da haka, injin turbin mai kwararar iska na axial yana da nakasa kuma yana iyakance iyakokin amfaninsa. Manyan gazawar sune:
1. Yawan ruwan wukake ƙanana ne, kuma cantilever ne, don haka ƙarfinsa ba shi da kyau, kuma ba za a iya amfani da shi a tashoshin samar da wutar lantarki na matsakaici da tsayi ba.
2. Saboda yawan kwararar na'urar da kuma saurin na'urar, tana da ƙaramin tsayin tsotsa fiye da injin turbine na Francis a ƙarƙashin yanayin kai ɗaya, wanda ke haifar da zurfin haƙa rami mai yawa don harsashin tashar wutar lantarki da kuma babban jari.
Bisa ga gazawar da aka ambata a sama na injinan kwararar axial, ana amfani da sabbin kayan aiki masu ƙarfi wajen kera injinan kwararar axial kuma ana inganta ƙarfin ruwan wukake a cikin ƙira, don haka ana ci gaba da inganta kan aikace-aikacen injinan kwararar axial. A halin yanzu, kan aikace-aikacen injinan kwararar axial-flow yana tsakanin mita 3 zuwa 90, kuma ya shiga yankin injinan Francis. Misali, matsakaicin fitarwa na injinan kwararar axial-flow na ƙasashen waje shine 181,700 kW, matsakaicin kan ruwa shine 88m, kuma diamita mai gudu shine mita 10.3. Matsakaicin fitarwa na injinan guda ɗaya na injinan kwararar axial-flow da aka samar a ƙasata shine 175,000 kW, matsakaicin kan ruwa shine mita 78, kuma matsakaicin diamita mai gudu shine mita 11.3. Injin kwararar axial-flow yana da ruwan wukake masu ƙarfi da tsari mai sauƙi, amma ba zai iya daidaitawa da tashoshin wutar lantarki tare da manyan canje-canje a kan ruwa da kaya ba. Yana da kan ruwa mai ƙarfi kuma yana aiki a matsayin kayan tushe ko tashar wutar lantarki mai girma da yawa. Idan ƙarfin yanayi ya yi yawa, ana iya kwatanta tattalin arziki. Ana iya la'akari da shi. Matsakaicin kan sa shine 3-50m. Turbines na paddle-flow gabaɗaya suna amfani da na'urori a tsaye. Tsarin aikinsa iri ɗaya ne da na turbines na Francis. Bambancin shine lokacin da nauyin ya canza, ba wai kawai yana daidaita juyawar vanes na jagora ba. , Yayin da kuma daidaita juyawar ruwan wukake masu gudu don kiyaye ingantaccen aiki.
A da, mun kuma gabatar da injinan Francis. Daga cikin injinan samar da injinan turbine, har yanzu akwai babban bambanci tsakanin injinan Francis da injinan axial flow turbines. Misali, tsarin injinan su ya bambanta. Ruwan wukake na injinan Francis kusan suna daidai da babban shaft, yayin da injinan axial flow turbines kusan suna daidai da babban shaft.
