Kunyatsoongorora kwakayerwa muma microns kunoita kuti simba risvike muma megawatts.
Munyika yesimba rinodzokororwa, simba remvura rinoramba riri dombo guru rekugadzira magetsi akavimbika. Shure kwematurbine makuru nemajenareta anoshandisa simba remvura kune gamba risingazivikanwe: Computer Numerical Control (CNC) machining. Iyi tekinoroji yekugadzira yepamusoro yave yakakosha mukugadzira zvinhu zvakaoma zvinoita kuti simba remvura rikwanisike, kubva kumaturbine makuru kusvika kumabushings nemabushings akagadzirwa nemazvo.
Michina yeCNC inogona kushivirira kusvika pama micrometer mana—inenge muganho unodiwa pakugadzira simba remagetsi emvura—zvichivimbisa kuti michina inoshanda zvakanaka pasi pekumanikidzwa kukuru kwemvura.
01. Kuchinja Kugadzirwa kweTurbine Component
Chinhu chikuru chesimba remagetsi emvura iturbine yayo, uye michina yeCNC yakachinja magadzirirwo anoitwa zvinhu izvi zvakakosha. Matangi emvura, kunyanya ayo eFrancis neKaplan turbines, ane nzvimbo dzakaoma, dzakagadzirwa dzinofanira kunamatira kumaprofile chaiwo ehydrodynamic kuti awedzere kushanda zvakanaka kwesimba.
Nzira dzechinyakare dzekugadzira dzinosanganisira "kukanda jecha - kukuya nemaoko - kuongorora template yedhimendi" hadzina kukwanisa kunyatsovimbisa kururama uye kunaka kwenzvimbo idzi dzakaomarara.
Kuunzwa kwemashini eCNC ane mativi mashanu panguva imwe chete kwakagadzirisa zvipingamupinyi izvi. Iyi tekinoroji inogonesa kushandiswa kwakakwana kwemajini makuru eturbine mune imwe chete, ichichengetedza kurongeka kweprofile yepamusoro mukati me0.02mm/m—chinhu chakakosha chekuona kushanda zvakanaka kweturbine uye kugadzikana kwekushanda kwayo.
Kune zvikamu zvakakura zvakaita semakesi eturbine nemashaft, zvinogona kusvika dhayamita yemamita makumi mana nemaviri uye huremu hunopfuura matani mazana matatu nemakumi mashanu, michina yeCNC ndiyo chete nzira inogoneka yekugadzira. Kugona kwavo kubata zvikamu zvakakura kudaro uku vachichengetedza kurongeka kunoita kuti zvive zvakakosha mukugadzira magetsi emvura.
02. Kupfuura Turbines: Mashandisirwo Akakwana eHydropower
Kushandiswa kweCNC machining mu hydropower kunopfuura kugadzirwa kweturbine. Tekinoroji iyi inoita basa rakakosha mukugadzira madhamu nemagedhi ezviteshi zvemagetsi, izvo zvinoda kudzorwa kwakanyatsojeka kuti zvishande zvakanaka pasi pekumanikidzwa kwemvura kwakanyanya.
Makambani akaita seVoith Hydro akagadzira michina yeCNC, achigadzira nzira yekugadzira michina yakabatana inobvumira vashandi kuti vakwanise kutarisira michina yakawanda zvakanaka. Kugadzira michina iyi kwakaderedza zvakanyanya nguva yekugadzirisa michina ukuwo kuchivandudza kuchinjika kwekugadzirwa.
Tekinoroji iyi inobvumirawo kugadziriswa nekugadziriswa kwemidziyo yemagetsi iripo nemazvo. Michina yeCNC yakasarudzika inogona kudzorera zvikamu zvakasakara kumamiriro azvo epakutanga, zvichiita kuti nguva yebasa iwedzere uye kudzivirira mari yekutsiva zvachose.
03. Hunyanzvi hwehunyanzvi hunosimudzira kufambira mberi kwesimba remvura
Kushanduka kwetekinoroji yeCNC kwakabatsira zvakananga mukuvandudza mashandiro emagetsi emvura uye kuvimbika. Kugadzira CNC ine axis yakawanda kunobvumira vagadziri kugadzira zvinhu zvine jiometri dzakaoma izvo zvaisazogoneka nenzira dzemazuva ano.
Masisitimu emazuva ano eCNC anosanganisira matekinoroji ekufananidzira anogadzira mapatya edhijitari ekugadzirisa michina. Maekisesaizi aya anoona kusawirirana pakati pezvishandiso, maworkpiece, uye zvinhu zvekugadzirisa michina usati watanga kucheka, zvichidzivirira zvikanganiso zvinodhura uye zvichideredza nguva yekugadzirisa.
Vagadziri vekuChina vafambira mberi zvikuru mundima iyi. Makambani akaita seKede CNC akagadzira nzvimbo dzekugadzira michina dzakamira dzakaita mativi mashanu kusanganisira modhi yeKMC1250 yakagadzirirwa kugadzirwa kwezvikamu zvemagetsi emvura.
Michina iyi yepamusoro inogona kuita mabasa ekugadzira nekugadzirisa nemazvo pamavharuvhu makuru, magedhi, mapaipi esimbi anomanikidzwa, uye mimwe michina yemagetsi emvura.
Kubatanidzwa kwemasisitimu eCAD/CAM neCNC machining kwakaita kuti maitiro ekugadzira ave nyore. Data rekugadzira rinoyerera zvakanaka kubva kuinjiniya kuenda kukugadzira, zvichideredza zvikanganiso zvekushandura uye nekukurumidzisa nguva yekugadzira.
Iyi tambo yedhijitari inonyanya kukosha mumagetsi emvura, uko zvikamu zvakawanda zvinogadzirwa zvakagadzirirwa mapurojekiti chaiwo pane kugadzirwa nevanhu vakawanda.
