Fa'idodin injin turbin kwararar axial
Idan aka kwatanta da Francis turbine, axial-flow turbine yana da manyan fa'idodi masu zuwa:
1. Babban saurin da kuma kyawawan halaye na makamashi. Saboda haka, saurin na'urarsa da kwararar na'urar sun fi na Francis turbine girma. A ƙarƙashin yanayi iri ɗaya da fitarwa, yana iya rage girman na'urar samar da injin turbine mai amfani da ruwa sosai, rage nauyin na'urar da kuma adana amfani da kayan aiki, don haka yana da fa'idodi masu yawa na tattalin arziki.
2. Siffar saman da kuma kaurin saman ruwan wukake masu gudu na injin turbin axial-flow suna da sauƙin cika buƙatun masana'antu. Saboda ruwan wukake na injin turbin axial flow propeller na iya juyawa, matsakaicin inganci ya fi na injin turbin Francis girma. Lokacin da kaya da kai suka canza, ingancin aikin ba ya canzawa sosai.
3. Ana iya wargaza ruwan wukake masu gudu na injin turbin axial flow paddle domin sauƙaƙe kera da jigilar su.
Saboda haka, injin turbin mai gudana a cikin axial-flow yana tsayawa a cikin babban kewayon aiki, ba shi da girgiza sosai, kuma yana da inganci da fitarwa mai yawa. A cikin kewayon ƙaramin kan ruwa, kusan yana maye gurbin injin turbin Francis. A cikin 'yan shekarun nan, ya sami babban ci gaba da amfani mai yawa dangane da ƙarfin naúrar guda ɗaya da kan ruwa.
3, Rashin amfani da injin turbin kwararar axial
Duk da haka, injin turbin axial-flow shima yana da rashin amfani kuma yana iyakance iyakokin amfaninsa. Manyan rashin amfaninsa sune:
1. Adadin ruwan wukake ƙanana ne kuma cantilever ne, don haka ƙarfin ba shi da kyau kuma ba za a iya amfani da shi a tashoshin 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 kan ruwa ɗaya, wanda ke haifar da zurfin haƙa rami mai yawa da kuma saka hannun jari mai yawa a cikin harsashin tashar wutar lantarki.
Bisa ga gazawar da aka ambata a sama na injin turbin kwararar axial, ana ci gaba da inganta kan aikace-aikacen injin turbin kwararar axial ta hanyar ɗaukar sabbin kayayyaki masu ƙarfi da juriya ga cavitation a cikin kera injin turbin da kuma inganta yanayin damuwa na ruwan wukake a cikin ƙira. A halin yanzu, kewayon kan aikace-aikacen injin turbin kwararar axial shine mita 3-90, wanda ya shiga yankin injin turbin Francis. Misali, fitowar injin * * * guda ɗaya na injin turbin kwararar axial na ƙasashen waje shine 181700 kW, kan * * * shine mita 88, kuma diamita mai gudu shine mita 10.3. Fitar guda ɗaya na injin turbin kwararar axial da aka samar a China shine 175000 kW, kan * * * shine mita 78, kuma diamita na mai gudu shine mita 11.3. Injin turbin kwararar axial da aka gyara yana da ruwan wukake da tsari mai sauƙi, amma ba zai iya daidaitawa da tashoshin wutar lantarki ba tare da manyan canje-canje a kan ruwa da kaya. Ga manyan tashoshin samar da wutar lantarki na ruwa masu tsayayyen kan ruwa kuma suna aiki a matsayin nauyin tushe ko na'urori da yawa, ana iya la'akari da shi bayan kwatanta tattalin arziki lokacin da makamashin lantarki na yanayi ya yi yawa. Matsakaicin kan ruwa da ya dace shine mita 3-50. Turbine mai samar da wutar lantarki na Axial yawanci yana ɗaukar na'urar tsaye, kuma aikin sa iri ɗaya ne da na turbine na Francis. Bambancin shine lokacin da nauyin ya canza, ba wai kawai yana daidaita juyawar vane na jagora ba, har ma yana daidaita juyawar ruwan mai gudu don kiyaye ingantaccen aiki.
Mun kuma gabatar da injin Francis turbine a baya. Daga cikin injinan samar da wutar lantarki, injin Francis turbine ya bambanta sosai da injin axial-flow. Misali, siffofin tsarin injin su sun bambanta. Ruwan wukake na injin Francis turbine kusan suna daidai da babban shaft, yayin da na injin axial flow turbine kusan suna daidai da babban shaft.
