1. Tikanga mahi
Ko te turbine wai te kaha o te rere wai.Ko te turbine wai te miihini hiko e huri ana i te kaha o te rere o te wai ki te hiko hurihuri.Ko te wai kei roto i te puna wai whakarunga ka arahina atu ki te turbine ma te paipa whakahuri, e turaki ai te kaikawe turbine ki te huri me te turaki i te hiko ki te whakaputa hiko.
Ko te tātai tātaitanga o te mana whakaputa turbine e whai ake nei:
P＝9．81H·Q· η（ P-hiko mai i te hiko hiko, kW;H – te upoko wai, m;Q – rere i roto i te turbine, m3 / S;η— Te kaha o te hiko hiko
Ko te teitei ake o te upoko h me te nui o te tukunga Q, ko te teitei ake o te kaha o te turbine η Ko te teitei ake o te kaha, ko te kaha ake o te whakaputa.
2. Te whakarōpūtanga me te upoko e tika ana mo te turbine wai
Te whakarōpūtanga turbine
Mirohiko tauhohenga: Francis, rere axial, rere oblique me te turbine ngongo
Pelton turbine: Pelton turbine, oblique stroke turbine, double stroke turbine me Pelton turbine
Rere whakauru poutū
Te rere axial poutū
Te rere titaha
Upoko e tika ana
Hurihuri tauhohenga:
Francis turbine 20-700m
Turbine rere tuaka 3 ～ 80m
He hurihanga rere titaha 25 ~ 200m
Tubular turbine 1 ~ 25m
Hurihuri hiko:
Pelton turbine 300-1700m (nui), 40-250m (iti)
20 ～ 300m mo te turbine paheketanga tahataha
Pāwhiri-taurua te turbine 5 ～ 100m (iti)
Ko te momo turbine ka tohua kia rite ki te upoko mahi me te tere motuhake
3. Nga tawhā mahi taketake o te hiko hiko
Kei roto i te nuinga o te upoko h, te rere Q, te putanga P me te kakama η、 Tere n.
Uhunga H:
Te upoko teitei Hmax: te upoko kupenga teitei e whakaaetia ana kia mahi te turbine.
Hmin upoko iti: te upoko kupenga iti mo te mahi haumaru me te pumau o te miihini hiko.
Upoko toharite taumaha ha: uara toharite taumaha o nga upoko wai katoa o te miihini hiko.
Te upoko kua tohua HR: te upoko kupenga iti rawa e hiahiatia ana mo te turbine ki te whakaputa i nga putanga whakatau.
Tukunga Q: te rōrahi rere e haere ana i roto i te wahanga rere o te kapohau i roto i te wa wae, he m3 / s te waeine e whakamahia ana.
Tere n: te maha o nga hurihanga o te kaikawe hiko i roto i te wa wae, e whakamahia nuitia ana i te R / min.
Putanga P: te mana whakaputa o te mutunga o te porohurihuri, te waeine e whakamahia ana: kW.
kakama η： Ko te ōwehenga o te mana whakauru ki te mana whakaputa o te miihini hiko e kiia ana ko te pai o te miihini hiko.
4. Hanganga matua o te turbine
Ko nga waahanga hanganga matua o te hurihanga tauhohenga ko te volute, te mowhiti noho, te tikanga arahi, te uhi o runga, te kaikawe, te rakau matua, te arahi arahi, te mowhiti o raro, te ngongo tauira, me era atu. Ko nga pikitia o runga ake nei e whakaatu ana i nga waahanga hanganga matua o te miihini.
5. Whakamātautau wheketere o te hikohiko waipēhi
Tirohia, mahi me te whakamatautau i nga waahanga matua penei i te volute, te kaikawe, te rakau matua, te servomotor, te arahi arahi me te uhi o runga.
Te tirotiro matua me nga mea whakamatautau:
1) Te tirotiro i nga rawa;
2) Te tirotiro welding;
3) Nga whakamatautau kore kino;
4) Te whakamatautau pehanga;
5) Taki rahi;
6) Huinga wheketere;
7) Te whakamatautau nekehanga;
8) Runner static balance test, etc.
