Okwu Mmalite Dị Mkpirikpi nke Ngwa Turbine na Osisi Ike Mmiri

1. Ụkpụrụ ọrụ
Turbine mmiri bụ ike nke mmiri na-asọ. Turbine mmiri bụ igwe ike nke na-agbanwe ike nke mmiri na-asọ ka ọ bụrụ ike igwe na-agbagharị agbagharị. Mmiri dị n'ebe a na-echekwa mmiri dị n'elu mmiri na-eduga na turbine site na paịpụ ntụgharị, nke na-akwali turbine na-agbagharị ma na-akwali jenereta iji mepụta ọkụ eletrik.

Usoro ngụkọ nke ike mmepụta turbine bụ dị ka ndị a:
P＝9．81H·Q· η（ Ike P sitere na ihe na-emepụta mmiri, kW; H – isi mmiri, m; Q – na-agafe na turbine, m3 / S; η— Arụmọrụ nke turbine hydraulic
Ka isi h dị elu ma ka Q dị elu, otú ahụ ka turbine si arụ ọrụ nke ọma η Ka ike dị elu, otú ahụ ka ike mmepụta si arụ ọrụ nke ọma.

2. Nhazi na isi turbine mmiri dị mkpa
Nhazi turbine
Turbine mmeghachi omume: Francis, axial flow, oblique flow na tubular turbine
Pelton turbine: Pelton turbine, oblique stroke turbine, double stroke turbine na Pelton turbine
Usoro ngwakọta kwụ ọtọ
Ọsọ axial kwụ ọtọ
Usoro mmiri gbara ọchịchịrị
Isi dị irè

Turbine mmeghachi omume:
Turbine Francis 20-700m
Turbine mmiri axial 3 ~ 80m
Turbine na-asọfe nke gbagọrọ agbagọ 25 ～ 200m
Turbine tubular 1 ~ 25m

Ngwakọta ikuku:
Pelton turbine 300-1700m (nnukwu), 40-250m (obere)
20 ～ 300m maka turbine mmetụta oblique
Turbine nke dị okpukpu abụọ 5 ～ 100m (obere)
A na-ahọrọ ụdị turbine ahụ dịka isi ọrụ na ọsọ akọwapụtara si dị

3. Ntọala ọrụ nke turbine hydraulic
Ọ gụnyere isi h, usoro Q, mmepụta P na arụmọrụ η、 Speed ​​n.
Isi njirimara H:
Isi kachasị elu Hmax: isi kachasị elu nke turbine ahụ kwere ka ọ rụọ ọrụ.
Isi kacha nta Hmin: isi kacha nta maka ọrụ nchekwa na nkwụsi ike nke turbine hydraulic.
Isi nkezi nha nha ya: uru nkezi nha nha nke isi mmiri niile nke turbine.
Isi HR a tụrụ aro: isi net kacha nta achọrọ maka turbine iji mepụta mmepụta a tụrụ aro.
Mwepụ Q: olu mmiri na-agafe na ngalaba mmiri nke turbine n'oge nkeji, nkeji a na-ejikarị eme ihe bụ m3 / s.
Ọsọ n: ọnụọgụ nke ntụgharị nke onye na-agba ọsọ turbine n'oge nkeji, nke a na-ejikarị eme ihe na R / min.
Mmepụta P: ike mmepụta nke njedebe ogwe turbine, nkeji a na-ejikarị eme ihe: kW.
arụmọrụ η: A na-akpọ oke ike ntinye na ike mmepụta nke turbine hydraulic arụmọrụ nke turbine hydraulic.

4. Isi nhazi nke turbine
Isi ihe owuwu nke turbine mmeghachi omume bụ volute, mgbanaka stay, usoro nduzi, mkpuchi elu, onye na-agba ọsọ, ogwe isi, ihe nduzi, mgbanaka ala, tube draft, wdg. Foto ndị dị n'elu na-egosi akụkụ nhazi bụ isi nke turbine ahụ.

5. Nnwale ụlọ ọrụ mmepụta ihe nke turbine hydraulic
Lelee, rụọ ọrụ ma nwalee akụkụ ndị bụ isi dịka volute, runner, main shaft, servomotor, guide bearing na top cover.
Isi ihe nyocha na nnwale:
1) Nnyocha ihe;
2) Nnyocha ịgbado ọkụ;
3) Nnwale na-anaghị emebi ihe;
4) Nnwale nrụgide;
5) Nyocha nha;
6) Mgbakọta ụlọ ọrụ mmepụta ihe;
7) Nnwale mmegharị;
8) Nnwale nhazi nke onye na-agba ọsọ, wdg.
