Ma hydraulic turbine ndiwo moyo wezviteshi zvemagetsi zvinoshandisa mvura, zvichishandura simba remagetsi uye rinokwanisa remvura inoyerera kuita kutenderera kwemagetsi, izvo zvinozoita kuti majenareta agadzire magetsi. Sezvo nyika ichitsvaga manyuko esimba anochengetedza uye akavimbika, dhizaini nekugadzirwa kwemichina iyi yakaoma kwave kwakakosha kupfuura kare. Chinyorwa chino chinoongorora maitiro akaomarara ekuunza hydraulic turbine kubva papfungwa kuenda kuchokwadi.
Chikamu 1: Chikamu Chekugadzira - Uko Mainjiniya Anosangana Nezvisikwa
Kugadzira turbine ye hydraulic ibasa rakaoma, rine mabasa akawanda rinoenzanisa mafambiro emvura, sainzi yezvinhu, mashandiro ekuvaka, uye kufunga nezvezvakatipoteredza. Rinotanga nemubvunzo unokosha: Nderupi rudzi rweturbine rwakakodzera nzvimbo yacho?
1.1 Kusarudzwa kweTurbine: Kufananidza Muchina neChishandiso
Sarudzo yeturbine inonyanya kuenderana nemusoro wenzvimbo (hurefu hwemvura inodonha) uye mwero wekuyerera kwayo.
Maturbine eImpulse (Pelton Wheel): Akanakira kushandiswa kwepamusoro-soro uye kuyerera zvishoma. MuPelton turbine, majeti emvura ane kumhanya kwakanyanya anorova mabhaketi akaita sechipunu akaiswa pamusoro pemumhanyi, achifambisa simba. Dhizaini yacho inotarisa pakugadzirisa mafambiro emabhaketi kuti atore simba rakawanda kubva mujeti.
Maturbine eReaction: Shandisa kumhanya uye kumanikidzwa kwemvura. Anonyudzwa mumvura.
Francis Turbine: Simba remagetsi rinogadzirwa nemvura, rakakodzera nzvimbo ine mafambiro epakati nepakati. Dhizaini yaro ine radial-inflow runner ine fixed guide vanes (stay vanes) uye mageti ewicket anogadziriswa kudzora kuyerera. Magadzirirwo akaomarara, akakombama emashizha ayo anoshamisa mukugadzira ma hydraulic.
Kaplan nePropeller Turbines: Yakagadzirirwa nzvimbo dzine misoro midiki, dzinoyerera zvakanyanya. Idzi iturbine dzinoyerera zvakanyanya, dzakafanana nepropeller yechikepe. Chinhu chikuru cheturbine yeKaplan nderekuti mapanga ayo anogona kugadziriswa panguva yekushanda (double-regulation) kuti arambe achishanda zvakanaka pasi pemamiriro akasiyana ekuyerera.
1.2 Maitiro Ekugadzira Dhijitari
Dhizaini yemazuva ano yeturbine inonyanya kushandiswa pakushandisa software yepamusoro uye maturusi ekufananidzira.
Computational Fluid Dynamics (CFD): CFD inokosha zvikuru. Mainjiniya vanogadzira 3D model ye turbine uye vanotevedzera kufamba kwemvura mairi. Izvi zvinovabvumira kuongorora kuparadzirwa kwepressure, kuona njodzi dze cavitation (kuumbwa kwemabubbles emhepo anogona kukuvadza pamusoro), uye kugadzirisa maumbirwo eblade kuti ashande zvakanaka uye atore simba nguva refu simbi isati yachekwa.
Kuongororwa Kwezvinhu Zvakakwana (FEA): Kunyange zvazvo CFD ichibata mvura, FEA inobata chimiro. Iyi software inotevedzera kushushikana kwemuchina, kudedera, uye kukanganisika kwezvikamu zve turbine pasi pemitoro yakanyanya ye hydraulic. Inoita kuti runner, shaft, uye casing zvigone kumira kwemakumi emakore ekushanda pasina kukundikana.
Kuedzwa kweModhero: Pasinei nesoftware yepamusoro, mamodheru echikero chemuviri (kazhinji 1:5 kusvika 1:10) achiri kugadzirwa uye kuyedzwa mumarabhoritari akasarudzika. Ruzivo kubva kumamodheru aya runoshandiswa kusimbisa nekunatsiridza simulations dzedhijitari, zvichipa kusimbiswa kwekupedzisira kwevimbiso dzekushanda.
Chikamu 2: Chikamu Chekugadzira - Kubva Pazvinhu Zvisina Kugadzirwa Kuenda Kuchikamu Chesimba
Kana dhizaini yacho yapera uye yasimbiswa, maitiro ekugadzira anotanga nekungwarira.
2.1 Kusarudzwa Kwezvinhu
Zvikamu zveturbine zvinoshanda munzvimbo ine kumanikidzwa kwakanyanya, kukurwa kwevhu, uye kukuvara kunogona kuitika. Chinhu chikuru chinowanzova simbi isina tsvina inonzi martensitic (semuenzaniso, CA6NM kana 13/4 steel), inosarudzwa nekuda kwekubatana kwayo kwakanaka kwesimba, kusimba, uye kuramba ngura.
2.2 Maitiro Akakosha Ekugadzira
Kugadzira: Zvikamu zvikuru zvakaita serunner, casing, uye stay rings zvinowanzogadzirwa kuburikidza nekuumba. Simbi yakanyungudutswa inodururwa mujecha rakaomarara kuti igadzire zvikamu zvine chimiro chenet. Maitiro aya anoda kunyatsorongeka kudzivirira zvikanganiso zvinogona kuva nzvimbo dzekukundikana.
Kugadzira: Zvikamu zvakakosha zvakaita semugodhi mukuru, unoburitsa torque yakakura, zvinowanzogadzirwa. Kugadzira kunoenderana nechimiro chesimbi, zvichiita kuti ive nehunyanzvi hwepamusoro hwemakanika uye inodzivirira kuneta.
Kugadzira Machining (CNC): Zvikamu zvakagadzirwa nesimbi uye zvakagadzirwa zvine maumbirwo akaomarara anoda kugayiwa nemazvo. Michina yeComputer Numerical Control (CNC) inoshandiswa kugayiwa, kutenderedzwa, uye kuboorwa kwezvikamu kusvika pahukuru hwazvo hwekupedzisira nematanho akasimba sechikamu chemirimita. Izvi zvakakosha zvikuru kune mabhurazi erunner, uko kupenya kwepamusoro uye geometry zvinokanganisa zvakananga kushanda zvakanaka.
Kusonta: Maturbine makuru akakura zvekuti haakwanise kuumbwa kana kugadzirwa sechinhu chimwe chete. Zvikamu zvishoma zvinosonta pamwe chete nevanobatanidza ma welders vane certification vachishandisa maitiro e automated kana robotic. Semuenzaniso, Francis runner inowanzogadzirwa nekusonta mablades ega ega pakorona nebhandi. Kurapa kupisa mushure mekusonta kwakakosha kuderedza kushushikana kwasara.
2.3 Kudzora Hunhu uye Kupedzisa
Kuvimbisa mhando yechinhu kunokosha padanho rega rega.
Kuedza Kusingaparadze (NDT): Matekiniki akadai seKuedza kweUltrasonic (UT) uye Kuongororwa kweDye Penetrant (PT) anoshandiswa kuona zvikanganiso zvemukati kana pamusoro pemawelds uye castings.
Kuenzanisa: Mumhanyi akaungana anoenzanisa zvinhu nemazvo. Kusawirirana kupi zvako kunogona kukonzera kudedera kukuru pakumhanya kwekushanda. Mumhanyi anotenderedzwa mumuchina wekuenzanisira, uye huwandu hudiki hwezvinhu hunowedzerwa kana kubviswa kusvika hwatenderera zvakanaka.
Kuputira: Kuti pave nekukwanisa kudzivirira kukurwa kwevhu uye kuputika kwevhu, nzvimbo dzakakosha dzemumhanyi, kunyanya mipendero yepamberi pemaburi, dzinogona kuputirwa nezvinhu zvakaoma kana kuti simbi isina ngura.
Ramangwana: Mafambiro muKugadzira neKugadzira Turbine
Indasitiri iyi iri kuramba ichichinja-chinja, ichikurudzirwa nezvinodiwa zvekuchinja-chinja, kuchengetedza nharaunda, uye kuchengetedza mari.
Mapatya eDigital: Kugadzira kopi chaiyo yeturbine chaiyo kunobvumira kutarisa panguva chaiyo, kugadzirisa mafambiro enguva, uye kugadzirisa mashandiro muhupenyu hwayo hwese.
Kugadzira Zvimwe (3D Printing): Kunyange zvazvo zvisati zvashandiswa kune vanotanga mitambo, kudhinda kwe3D kuri kuchinja kugadzirwa kwemaitiro akaomarara, mapatani ekudyara mari, uye zvikamu zvekutsiva, zvichideredza nguva yekuburitsa zvinhu.
Magadzirirwo Akakodzera Hove: Pane kusimbiswa kuri kukura pakugadzira maturbine anobvumira kufamba kwehove zvakachengeteka, nejometri dzakagadziriswa uye kumhanya kunononoka kutenderera kuderedza kukuvara.
Tekinoroji yeKumhanya Kunochinja-chinja: Maturbine emazuva ano, kunyanya munzvimbo dzinochengeterwa zvinhu zvinopomba, ari kugadzirwa kuti ashande nekumhanya kunochinja-chinja, zvichivabvumira kuwedzera kushanda zvakanaka mumagetsi akasiyana-siyana uye kupa kugadzikana kuri nani kwegrid.
