Mvura Turbine Runners: Mhando uye Technical Specifications

Maturbine emvura ndiwo akakosha masystem mumahydropower masisitimu, achishandura simba rekuyerera kana kudonha kwemvura kuita magetsi emagetsi. Pamwoyo pekuita uku panemumhanyi, chikamu chinotenderera cheturbine chinopindirana zvakananga nekuyerera kwemvura. Dhizaini, mhando, uye tekinoroji yekumisikidza yemumhanyi yakakosha pakuona kugona kweturbine, mashandiro emusoro wemusoro, uye mamiriro ekushandisa.

1. Kurongwa kweMvura Turbine Runners

Vamhanyi veturbine yemvura vanowanzoiswa mumapoka matatu makuru zvichienderana nerudzi rwekuyerera kwemvura yavanobata:

A. Impulse Runners

Impulse turbines inoshanda nehigh-velocity mvura jets inorova mablades ekumhanya mumhepo yemhepo. Vamhanyi ava vakagadzirirwakumusoro-soro, kuderera-kuyereraapplications.

• Pelton Runner:

  • Chimiro: Mabhakiti akaita chipunu akaiswa padivi pevhiri.

  • Head Range: 100-1800 mamita.

  • Speed: Low rotational speed; kazhinji kunoda kukurumidza kuwedzera.

  • Applications: Nzvimbo dzemakomo, off-grid micro-hydropower.

B. Reaction Vamhanyi

Reaction turbines inoshanda nekumanikidza kwemvura kuchinja zvishoma nezvishoma sezvo ichipfuura nemumhanyi. Vamhanyi ava vanonyudzwa uye vanoshanda pasi pemvura.

• Francis Runner:

  • Chimiro: Yakasanganiswa kuyerera nemukati radial uye axial kufamba.

  • Head Range: 20-300 mamita.

  • Kubudirira: High, kazhinji pamusoro pe90%.

  • Applications: Inoshandiswa zvakanyanya mune yepakati-musoro hydro zviteshi.

• Kaplan Runner:

  • Chimiro: Axial inoyerera mumhanyi ane mashizha anogadziriswa.

  • Head Range: 2-30 mamita.

  • Features: Mablades anogadziriswa anobvumira kushanda kwepamusoro pasi pemitoro yakasiyana.

  • Applications: Musoro wakaderera, nzizi dzakakwirira-kuyerera uye kushandiswa kwemvura.

• Propeller Runner:

  • Chimiro: Yakafanana neKaplan asi ine mashizha akaiswa.

  • Kubudirira: Optimal chete pasi penguva dzose kuyerera mamiriro.

  • Applications: Diki hydro saiti ine yakagadzikana kuyerera uye musoro.

C. Dzimwe Mhando dzeMumhanyi

• Turgo Runner:

  • Chimiro: Majeti emvura anorova mumhanyi pakona.

  • Head Range: 50-250 mamita.

  • Advantage: Yakakwira yekutenderera kumhanya kupfuura Pelton, iri nyore kuvaka.

  • Applications: Zviteshi zvemagetsi zvidiki-kusvika-pakati.

• Cross-Flow Runner (Banki-Michell Turbine):

  • Chimiro: Mvura inoyerera kuburikidza nemumhanyi transversely, kaviri.

  • Head Range: 2-100 mamita.

  • Features: Yakanaka kune diki hydropower uye inoshanduka kuyerera.

  • Applications: Off-grid masisitimu, mini hydro.

2. Key Technical Specifications yeVamhanyi

Mhando dzakasiyana dzevamhanyi dzinoda kunyatsotariswa kune yavo tekinoroji paramita kuti ive nechokwadi chekuita kwakakwana:

3. Mamiriro ekusarudza

Pakusarudza rudzi rwemumhanyi, mainjiniya anofanirwa kufunga nezve:

• Musoro uye Kuyerera: Inosarudza kusarudza zvekufungidzira kana kuita.

• Site Conditions: Kusiyana kweRwizi, sediment mutoro, kuchinja kwemwaka.

• Operational Flexibility: Inoda kugadziriswa kweblade kana kuyerera kuchinjika.

• Mutengo uye Maintenance: Vamhanyi vakapusa sePelton kana Propeller vari nyore kuchengetedza.

4. Future Trends

Nekufambira mberi mune computational fluid dynamics (CFD) uye 3D simbi kudhinda, turbine runner dhizaini iri kumukira yakananga:

• Kunyanya kushanda zvakanaka mukuyerera kwakasiyana

• Customized vamhanyi nokuda chaiyo saiti mamiriro

• Kushandiswa kwezvinhu zvakaumbwa zvemagetsi akareruka uye asingadziviriri blades

Mhedziso

Vamhanyi ve turbine yemvura ndiyo ibwe rekona rekushandurwa kwesimba re hydropower. Nekusarudza yakafanira rudzi rwemumhanyi uye nekukwenenzvera ayo tekinoroji paramita, hydropower zvidyarwa zvinokwanisa kuwana hunyanzvi hwepamusoro, hupenyu hwesevhisi refu, uye kuderedzwa kwezvakatipoteredza. Ingave yezvidiki-zvidiki zvekumaruwa magetsi kana mahombe-akabatanidzwa magidhi, mumhanyi anoramba ari kiyi yekuvhura kugona kuzere kwehydropower.
