Musiyano uripo pakati peWind Turbine Rotor neBlades
Maturbine emhepo ndeimwe yematekinoroji anozivikanwa zvikuru esimba rinodzokororwa uye ari kushandiswa zvakanyanya munyika dzakasiyana-siyana. Seri kwechimiro chavo chinoshamisa—chakareba pamusoro pevhu ne "feni" hombe, inotenderera—kune zvikamu zvakasiyana-siyana, chimwe nechimwe chine basa racho. Mazwi maviri anowanzo nzwika pakutaura nezvematurbine emhepo irotor nemablades. Vanhu vazhinji vanofunga kuti akafanana, asi rimwe nerimwe rinoreva chikamu chakasiyana chesystem yeturbine. Chinyorwa chino chinokurukura mutsauko uripo pakati pemarotor eturbine emhepo nemablades, zvichifukidza tsananguro dzawo, mabasa, maumbirwo, uye mabasa mukushandura simba remhepo kuita magetsi.
Kunzwisisa Hurongwa Hwekutanga hweWind Turbine
Usati wasiyanisa marotor nemablades, zvakakosha kuti utarise pfungwa yakajairika ye wind turbine. Kazhinji, wind turbine ine shongwe, nacelle (injini inogara pamusoro peshongwe), rotor, jenareta, control system, uye yaw system. Pazvinhu izvi zvese, chikamu chinonyatso shanda nemhepo i rotor, ine mablades, chinhu chikuru chinobata simba remhepo.
Chii Chinonzi Wind Turbine Blades?
Mapazi emhepo ane zvikamu zvakaita semapapiro zvinotenderera kana zvasangana nemhepo. Mapazi emazuva ano anowanzova nemapazi matatu (kunyangwe magadzirirwo ane mapazi maviri kana kupfuura aripo). Pakushanda, mapazi ndiwo "maturusi ekubata" makuru anoshandura simba remhepo kuita simba rekusimudza nekudhonza, izvo zvinozoburitsa kutenderera.
Hunhu hweNereza
1. Chimiro cheAerodynamic
Mapadza akagadzirwa zvakafanana nemapapiro endege. Dhizaini iyi inobvumira mhepo kupfuura pamusoro pemapadza kuti igadzire musiyano wekumanikidzwa, izvo zvinoita kuti pave nekusimudzwa. Izvi ndizvo zvinoita kuti mapadza atenderere zvakanaka, pane kungosundirwa nemhepo sepropeller yenguva dzose.
2. Zvikamu
Mapadza emazuva ano anowanzogadzirwa nezvinhu zvakaita sefiberglass, carbon fiber, epoxy resin, nezvimwe zvinhu zvakareruka asi zvakasimba. Izvi zvinoita kuti mapadza akwanise kutsungirira mitoro inorema, kuneta, uye mamiriro ekunze akaipisisa.
3. Saizi uye Kureba
Kureba kwebanga kunosiyana zvikuru zvichienderana nekukwanisa kwetangi. Matangi ekunze, mapanga anogona kureba mamita makumi maviri. Pamatangi ekunze, mapanga anogona kusvika pamamita anopfuura 80–100 pabanga rega rega.
4. Sisitimu yeKukanda (Kugadzika Angle yeBlade)
Maturbine mazhinji anoshandisa sisitimu yepitch kuti achinje angle yemablades kana tichienzanisa nemhepo. Izvi zvinobatsira pakudzora kumhanya kwekutenderera kwerotor, kugadzirisa kugadzirwa kwemagetsi, uye kudzivirira turbine mumhepo ine simba.
Chii chinonzi Wind Turbine Rotor?
Rotor chikamu chimwe chete chinotenderera chinosanganisira mapanga ne hub (pakati pe rotor panobatanidzwa mapanga). Nemamwe mashoko, mapanga chikamu che rotor, asi rotor haisi kungova mapanga chete. Rotor ndiyo "gungano" rine basa rekutora simba remhepo uye kuritumira sesimba remagetsi rinotenderera kuenda kushaft yakabatana nejenareta.
Zvikamu zveRotor
1. Nzvimbo yekubatsira
Hub ndiyo chikamu chepakati cherotor chinobatanidza mashizha kune chimiro chikuru cheturbine. Hub yakagadzirwa kuti ive yakasimba zvikuru nekuti inotsigira mutoro wekudhonza, wekutenderera, uye unoshanduka panguva yekushanda kweturbine.
2. Chipande
Mapazi acho akabatanidzwa pahub uye ndiwo simba guru rekufambisa rotor kana yabata mhepo.
3. Sisitimu yeKukanda (Kana Yakabatanidzwa)
Mumagadzirirwo akawanda, nzira yekupinda nayo iri munzvimbo yehub, saka rotor inowanzobatanidzwa nehurongwa hwekugadzirisa kona yeblade.
Basa reRotor
Rotor ine basa guru se:
– Chinogamuchira simba remhepo muchimiro chesimba remhepo.
– Inoshandura simba remhepo kuita simba remagetsi rinotenderera.
- Inotumira torque kune system yedrivetrain (gearbox kana direct drive) kuti ifambise jenareta.
Kusiyana Kukuru Pakati PemaRotor NemaBlades
Zvinotevera ndizvo musiyano mukuru pakati pemarotor emhepo nemashizha zvichibva pane zvimwe zvinhu zvakakosha:
1. Tsanangudzo: Chikamu vs. Kubatana kweSisitimu
– Chipande chimwe chezvinhu—chikamu che“bapiro”—chinoshanda zvakananga nemhepo.
- Rotor ndiyo chikamu chose chinotenderera chine maburi ne hub (uye kazhinji chinosanganisira michina inobatanidzwa).
Muenzaniso wakapfava: mapanga akaita se "maovha", nepo rotor yakaita se "chikamu chinotyaira chikepe chekukwasva" chinosanganisira maovha neshaft yadzo inobatanidza.
2. Basa: Kubata Mhepo vs. Simba Rinoyerera
– Mapazi acho ane basa rekubata mhepo uye kugadzira masimba emhepo anokonzera kutenderera.
- Rotor ine basa rekuunganidza kutenderera kwemaburi, kuadzikamisa nemakanika, uye kutumira torque ku turbine shaft.
3. Maumbirwo: Chimiro cheAerodynamic vs Maumbirwo eMechanical
– Mapazi anotarisa pakugadzirwa kwemhepo: chimiro chemhepo, kutenderedza banga, uye kutetepa kuti zvishande zvakanaka.
- Rotor ine chimiro chakaoma kunzwisisa chemuchina: hub, majoints, mabhaudhi, pitch system, uye load transfer points kuenda kushaft.
4. MaParamita Ekushanda Ataurwa
- Kana vanhu vachitaura nezvekureba kwebanga, zvinowanzoenderana nekugona kubata mhepo uye nzvimbo yekutsvaira.
- Vanhu pavanotaura nezve dhayamita ye rotor kana nzvimbo yakatsvairwa, vanotaura nezvekufukidza kwese kwema blades senzira imwe chete ye rotor.
Mukugadzira simba remhepo, nzvimbo yakatsvairwa nerotor inokosha nekuti simba rinogona kutorwa neturbine rinoenderana nenzvimbo iyi. Zvichitaurwa zviri nyore, kana dhayamita yerotor yakakura, simba rinogona kutorwa zvakanyanya (chero bedzi dhizaini nemamiriro emhepo zvakanaka).
5. Kugadzirisa uye Njodzi Yekukundikana
– Mapazi anogona kukanganiswa nekukukurwa kwemiromo yemapazi nekuda kwemvura/tunhu, mheni, uye kukuvara kwenzvimbo izvo zvinoderedza kushanda kwemhepo.
– Pamusoro pemamiriro ebanga, marotor anogonawo kusangana nematambudziko ne hub, mabearings, kana pitch system. Kukuvadzwa kwerotor kunowanzo kuve kwakaoma nekuti kunosanganisira kusimba kwese kwemuchina.
Sei Musiyano Uyu Uchikosha?
Kusiyanisa pakati pemarotor nemablades haisi nyaya yekutaura chete. Muchokwadi, musiyano uyu wakakosha kune:
1. Kutaurirana kwakakodzera kwehunyanzvi
Mumishumo yekuongorora, magadzirirwo, kana kutenga zvikamu, kutaura nezve "rotor" kana "blade" kuchireva kunogona kutungamira pakutsanangurwa zvisirizvo.
2. Kuverenga mashandiro eturbine
Magadzirirwo akawanda akadai se tip speed ratio, nzvimbo yakatsvairwa, uye miganhu yeruzha zvinonyanya kukosha kana tikanzwisisa kuti rotor ndiyo system yese inotenderera, kwete mablades chete.
3. Kuronga kugadzirisa uye mari yekushandisa
Kutsiva mablade kunosanganisira mari dzakasiyana uye maitiro ekugadzirisa rotor/hub kana pitch system. Kunzwisisa uku kunobatsira vashandi kuronga nguva yekuzorora uye kuona kuti basa ravo rakachengeteka.
Mhedziso
Muchidimbu, banga remhepo rine chimiro chakaita semapapiro rinobata simba remhepo uye rinogadzira simba remhepo kuti ritenderedze turbine. Panguva imwe chete, rotor yemhepo ine simba remhepo ndiyo inotenderera yese ine mablades ne hub (nenzira dzakabatana) inounganidza kutenderera uye inotumira torque kune drive system nejenareta. Mablades acho chikamu cherotor, asi rotor haisi mablades chete.
Nekunzwisisa misiyano iyi, tinogona kuverenga zvirevo zvema turbine zvakanyatsonaka, kunzwisisa mashandiro anoita ma turbine emhepo zvakakwana, uye kuona kuti dhizaini yechikamu chimwe nechimwe inobatsira sei mukugadzirwa kwemagetsi kubva musimba remhepo.
