Nkwalite ndị ahịa South Africa nke 200kW Kaplan Hydropower Plant Mechara Forster

N'oge na-adịbeghị anya, Forster nyeere ndị ahịa South Africa aka ịkwalite ike arụnyere nke ọdụ ụgbọ mmiri 100kW ya na 200kW.Atụmatụ nkwalite bụ nke a
200KW kaplan turbine generator
Isi ruru 8.15 m
Usoro nhazi 3.6m3/s
Oke kacha erute 8.0m3/s
Opekempe eruba 3.0m3/s
Enyere ikike arụnyere 200kW
Onye ahịa ahụ malitere ịkwalite ọdụ ụgbọ mmiri na Disemba afọ gara aga.Forster dochie turbine na generator maka ndị ahịa wee kwalite usoro njikwa.Mgbe ọ gbasasịrị isi mmiri site na 1m, a kwalitere ike arụnyere site na 100kW ruo 200kW, ma tinye usoro njikọ grid.Ka ọ dị ugbu a, ejirila nke ọma jikọọ na grid maka ike ọkụ, ndị ahịa na-enwekwa obi ụtọ

Uru nke Forster axial turbine
1. Ọsọ ọsọ dị elu na njirimara ike dị mma.Ya mere, ọsọ otu ya na ọsọ otu ya dị elu karịa nke turbine Francis.N'okpuru otu isi na ọnọdụ mmepụta, ọ nwere ike belata oke nke hydraulic turbine generator unit, belata ịdị arọ nke unit ma chekwaa ihe oriri, ya mere ọ nwere nnukwu uru akụ na ụba.
2. Ọdịdị elu na ọdịdị elu nke ndị na-agba ọsọ nke turbine axial-flow dị mfe iji mezuo ihe ndị a chọrọ n'ichepụta.N'ihi na agụba nke axial flow propeller turbine nwere ike ịtụgharị, nkezi arụmọrụ dị elu karịa nke turbine Francis.Mgbe ibu na isi gbanwere, arụmọrụ na-agbanwe ntakịrị.
3. Enwere ike ịkwasa eriri na-agba ọsọ nke axial flow paddle turbine iji kwado mmepụta na njem.
Ya mere, turbine axial-flow na-akwụsi ike n'ọtụtụ ọrụ dị ukwuu, na-enwe obere mkpọtụ, ma nwee nnukwu arụmọrụ na mmepụta.Na nso nke isi mmiri dị ala, ọ fọrọ nke nta ka ọ dochie anya turbine Francis.N'ime iri afọ ndị na-adịbeghị anya, o meela nnukwu mmepe na ngwa ngwa n'ihe gbasara otu ikike na isi mmiri.

Ọdịmma nke Forster axial turbine
1. Ọnụ ọgụgụ nke agụba dị obere na cantilever, ya mere ike adịghị mma na enweghị ike itinye ya na ọdụ ụgbọ mmiri na-ajụ na elu.
2. N'ihi na nnukwu unit eruba na elu unit ọsọ, o nwere a nta suction elu karịa Francis turbine n'okpuru otu mmiri isi, pụta na nnukwu gwupụtara omimi omimi na dịtụ elu ego nke ike ọdụ ntọala.

Dị ka adịghị ike ndị dị n'elu nke axial-flow turbine, isi ngwa nke axial-flow turbine na-aga n'ihu na-emewanyewanye site n'inwe ihe ọhụrụ na ike dị elu na cavitation na-eguzogide n'ichepụta turbine na imeziwanye ọnọdụ nrụgide nke agụba na imewe.Ka ọ dị ugbu a, isi ngwa ngwa nke axial flow propeller turbine bụ 3-90 m, nke batara na mpaghara ụgbọ mmiri Francis.
