Malo opangira magetsi oyendera madzi a axial-flow, omwe nthawi zambiri amakhala ndi ma turbine a Kaplan, ndi abwino kwambiri pamalo omwe ali ndi madzi otsika mpaka apakati komanso madzi ambiri. Ma turbine awa amagwiritsidwa ntchito kwambiri m'mapulojekiti a madamu oyenda mumtsinje komanso otsika chifukwa cha kugwira ntchito bwino komanso kusinthasintha kwawo. Kupambana kwa kukhazikitsa magetsi otere kumadalira kwambiri ntchito zomangamanga zopangidwa bwino komanso zochitidwa mosamala, zomwe zimapangitsa kuti ma turbine agwire bwino ntchito, kukhazikika kwa ntchito, komanso chitetezo.
1. Kukonzekera Malo ndi Kupatutsa Mtsinje
Ntchito yomanga nyumba isanayambe, kukonzekera malo ndikofunikira. Izi zikuphatikizapo kuchotsa malo omangira nyumba, kukonza misewu yolowera, ndi kukhazikitsa njira yosinthira madzi kuti madzi ayende bwino ndikupanga malo ogwirira ntchito ouma. Cofferdams—malo omangira osakhalitsa omangidwa mkati kapena kutsidya lina la mtsinje—nthawi zambiri amagwiritsidwa ntchito kupatula malo omangira nyumbayo ndi madzi.
2. Kapangidwe ka Kudya
Kapangidwe ka madzi m'malo olowera madzi kamayang'anira kulowa kwa madzi mu fakitole yamagetsi ndipo kamaonetsetsa kuti madzi akuyenda bwino komanso mokhazikika kupita ku turbine. Imakhala ndi malo osungira zinyalala, zipata, komanso nthawi zina malo oyeretsera zinyalala. Kapangidwe koyenera ka hydraulic ndikofunikira kwambiri kuti madzi asapangike, kuchepetsa kutayika kwa mutu, komanso kuteteza turbine ku zinyalala zoyandama.
3. Penstock kapena Open Channel
Kutengera ndi kapangidwe kake, madzi ochokera mu intake amatumizidwa ku turbine kudzera m'mapaipi otsekedwa kapena njira zotseguka. Mu mapangidwe ambiri a axial-flow—makamaka m'mafakitale otsika—intake yotseguka yolumikizidwa mwachindunji ku turbine imagwiritsidwa ntchito. Kukhazikika kwa kapangidwe kake, kufanana kwa kayendedwe ka madzi, ndi kuchepetsa kutayika kwa madzi ndi zinthu zofunika kwambiri panthawiyi.
4. Kapangidwe ka Mphamvu
Nyumba yamagetsiyi imakhala ndi chipangizo chopangira ma turbine, makina owongolera, ndi zida zothandizira. Pa ma turbine a Kaplan, omwe nthawi zambiri amayikidwa molunjika, nyumba yamagetsiyi iyenera kupangidwa kuti izithandiza katundu waukulu wa axial ndi mphamvu zosinthasintha. Kukhazikika kwa kugwedezeka, kuletsa madzi kulowa, komanso kusavuta kupeza pokonza ndi zinthu zofunika kwambiri pa kapangidwe ka nyumbayo.
5. Chitoliro cha Draft ndi Tailrace
Chubu chokoka madzi chimagwira ntchito yofunika kwambiri pobwezeretsa mphamvu ya kayendedwe ka madzi kuchokera m'madzi otuluka mu turbine. Chubu chokoka madzi chopangidwa bwino chimawonjezera magwiridwe antchito onse. Njira yolowera m'mbuyo imatumiza madzi bwino kubwerera kumtsinje. Mapangidwe onse awiriwa amafunika mawonekedwe oyenera kuti achepetse kugwedezeka ndi zotsatira za madzi akumbuyo.
6. Chipinda Chowongolera ndi Nyumba Zothandizira
Kupatula nyumba zazikulu, ntchito za zomangamanga zimaphatikizaponso kumanga zipinda zowongolera, malo ogona antchito, malo ogwirira ntchito, ndi nyumba zina zogwirira ntchito. Malo amenewa amatsimikizira kuti chomera chikugwira ntchito bwino komanso kuti chimasamalidwa kwa nthawi yayitali.
7. Zoganizira za Zachilengedwe ndi Zachilengedwe
Kufufuza nthaka, kukhazikika kwa malo otsetsereka, kuwongolera kukokoloka kwa nthaka, ndi kuteteza chilengedwe ndi zinthu zofunika kwambiri pakukonzekera zachitukuko. Njira zoyenera zotulutsira madzi, njira zodutsa nsomba (ngati pakufunika), ndi ntchito yokongoletsa malo zimathandiza kuchepetsa kuwonongeka kwa chilengedwe kwa polojekitiyi.
Gawo la uinjiniya wa zomangamanga la chomera chamagetsi chamagetsi choyenda ndi axial ndilofunikira kwambiri pakugwira ntchito kwake konse komanso kukhalitsa kwake. Kapangidwe kalikonse—kuyambira pa malo olowera mpaka pa malo otsetsereka—kayenera kupangidwa mosamala ndikumangidwa kuti kapirire mphamvu zamadzi, mikhalidwe ya nthaka, ndi zosowa za ntchito. Mgwirizano wapafupi pakati pa mainjiniya a zomangamanga, ogulitsa zida zamagetsi, ndi akatswiri azachilengedwe ndikofunikira kwambiri popereka yankho lotetezeka, lothandiza, komanso lokhazikika lamagetsi amadzi.
