Amfanin injin turbin axial
Idan aka kwatanta da injin turbine na Francis, injin turbin axial-flow yana da manyan fa'idodi masu zuwa:
1. Babban ƙayyadaddun ƙayyadaddun gudu da halaye masu kyau na makamashi.Saboda haka, saurin naúrar sa da naúrar sa ya fi na injin turbin Francis.A karkashin yanayi guda na kai da fitarwa, zai iya rage girman na'urar janareta na injin turbine, rage nauyin naúrar da adana kayan amfani, don haka yana da fa'idodin tattalin arziƙi.
2. Siffar da ke da tsayin daka da ƙwanƙwasa na masu gudu na axial-flow turbine suna da sauƙi don saduwa da bukatun a cikin masana'antu.Saboda ruwan wukake na axial flow propeller turbine na iya juyawa, matsakaicin inganci ya fi na Francis turbine.Lokacin da kaya da kai suka canza, ingancin ya canza kadan.
3. Za a iya tarwatsa ƙwanƙwasa masu gudu na axial flow paddle turbine don sauƙaƙe masana'antu da sufuri.
Sabili da haka, injin turbin axial-flow yana kiyaye kwanciyar hankali a cikin babban kewayon aiki, yana da ƙarancin girgiza, kuma yana da inganci da fitarwa.A cikin kewayon ƙananan shugaban ruwa, kusan ya maye gurbin injin turbin Francis.A cikin 'yan shekarun nan, ya yi babban ci gaba da aikace-aikace mai yawa dangane da iyawar naúrar guda ɗaya da shugaban ruwa.
3. Disadvantages na axial kwarara turbine
Koyaya, injin injin axial-flow shima yana da asara kuma yana iyakance iyakokin aikace-aikacen sa.Babban illolinsa sune:
1. Yawan ruwan wukake ƙanana ne kuma ƙanƙara, don haka ƙarfin ba shi da kyau kuma ba za a iya amfani da shi a matsakaici da manyan tashoshin wutar lantarki ba.
2. Saboda babban naúrar kwarara da kuma high naúrar gudun, yana da wani karami tsotsa tsawo fiye da Francis turbine karkashin wannan ruwa shugaban, sakamakon babban tono zurfin da in mun gwada da high zuba jari na wutar lantarki tushe.
Dangane da gazawar da ke sama na turbin axial-flow, shugaban aikace-aikacen injin injin axial-flow yana ci gaba da haɓaka ta hanyar ɗaukar sabbin kayan aiki tare da ƙarfi mai ƙarfi da juriya na cavitation a masana'antar injin injin da haɓaka yanayin damuwa na ruwan wukake a cikin ƙira.A halin yanzu, aikace-aikacen shugaban kewayon axial flow propeller turbine shine 3-90 m, wanda ya shiga yankin injin injin Francis.Misali, fitowar * * * injin guda ɗaya na injin turbine mai kwararar axial 181700 kW, shugaban * * * shine 88m, diamita mai gudu shine 10.3M.Fitar guda ɗaya na injin turbine mai kwararar axial da aka samar a China shine 175000 kW, shugaban * * * 78m, diamita na * * * mai gudu shine 11.3m.Axial kwarara kafaffen injin turbine yana da tsayayyen ruwan wukake da tsari mai sauƙi, amma ba zai iya daidaitawa da tashoshin wutar lantarki tare da manyan canje-canje a cikin ruwa da kaya ba.Don manyan tashoshin wutar lantarki tare da tsayayye kan ruwa da kuma yin aiki azaman nauyi mai tushe ko raka'a da yawa, ana iya kuma la'akari da shi bayan kwatankwacin tattalin arziki lokacin da makamashin lantarki na yanayi ya yawaita.Matsakaicin girman kai na ruwa shine 3-50m.Axial flow propeller turbine gabaɗaya yana ɗaukar na'urar a tsaye, kuma tsarin aikinsa daidai yake da na injin turbine Francis, Bambanci shine cewa lokacin da kaya ya canza, ba wai kawai yana daidaita jujjuyawar jagorar vane ba, har ma yana daidaita jujjuyawar injin ɗin. mai gudu ruwa don kula da babban inganci.
Mun kuma gabatar da injin turbin Francis a baya.Daga cikin injinan samar da ruwa, injin turbin na Francis ya sha bamban da turbine mai kwararar axial.Misali, tsarin tsarin mai tseren su ya bambanta.Wuraren injin turbine na Francis kusan sun yi daidai da babban mashigin, yayin da na axial flow turbine sun kusan kai tsaye zuwa babban shaft.
