Mashandisirwo Anoitwa Madhamu Emagetsi Nemvura: Tsananguro Yakadzama
Munguva ino yemazuva ano, kudiwa kwesimba rakachena uye rinogona kushandiswazve kuri kuwedzera nekukurumidza tichifunga nezvekukanganisa kwakashata kwemafuta efossil panharaunda. Imwe mhinduro inoshanda uye inoshandiswa zvakanyanya isimba remagetsi emvura. Madhamu, senzvimbo huru muhurongwa uhwu, anoita basa guru mukugadzira magetsi kubva mumvura. Chinyorwa chino chichatsanangura kuti madhamu anogadzira sei simba remagetsi emvura, ichifukidza misimboti yekutanga, zvikamu zvakakosha, uye mashandiro.
Nheyo Dzekutanga dzeMagetsi Emvura
Nheyo huru yesimba remagetsi rinotsamira pakushandisa simba rinogona kuwanikwa mumvura inochengetwa mudziva riri kuseri kwedhamu. Simba iri rinoshandurwa kuita simba remagetsi sezvo mvura ichiyerera ichidzika mupombi yepenstock ichienda kuturbine, uye pakupedzisira inoshandurwa kuita simba remagetsi nejenareta.
Chaizvoizvo, simba remagetsi rinoshandisa mvura rinobva pa "mutemo wekuchengetedza simba," uyo unoti simba harigone kugadzirwa kana kuparadzwa, asi rinogona kushandurwa kubva muchimiro chimwe kuenda kune chimwe. Muchiitiko ichi, simba regiravhiti remvura rinoshandurwa kuita simba remagetsi, uye rozopedzisira rava simba remagetsi.
Zvikamu Zvikuru muMasisitimu eMagetsi eMadziva
Kuti unzwisise kuti madhamu anogadzira sei magetsi, zvakakosha kuziva zvikamu zvikuru zvehurongwa hwemagetsi emvura:
1. Dhamu: Dhamu chivakwa chakavakirwa kuchengetedza mvura uye kugadzira dziva. Basa rayo nderekusimudzira huwandu hwemvura, nokudaro ichipa simba rakakwana rekufambisa turbine kana mvura yaburitswa.
2. Dziva: Dziva inzvimbo yekuchengetera mvura. Huwandu hwakawanda hwemvura mudziva hunoita kuti simba riwanikwe kunyangwe kana mvura yerwizi yadzikira.
3. Penstock: Penstock ipaipi hombe inotungamira mvura kubva mudura kuenda kuturbine. Penstock inoita basa rakakosha mukudzora mwero wekuyerera kwemvura uye kumanikidzwa kunodiwa kuti turbine ifambiswe.
4. Turbine: Turbine muchina unoshandura simba remvura kuita simba remuchina. Kana mvura ikayerera nepakati peturbine, mashizha eturbine anotenderera, zvichiburitsa simba remuchina.
5. Jenareta: Jenareta mudziyo unoshandura simba remakanika kubva muturbine kuita simba remagetsi kuburikidza nepfungwa ye electromagnetic induction.
6. MaTransformers neDistribution Networks: Matransformers anowedzera voltage yemagetsi anogadzirwa nemajenareta kuti aendeswe kune network yemagetsi, iyo inozogovera simba remagetsi kune vatengi vekupedzisira.
Maitiro Ekushanda KweSisitimu Yemagetsi Emvura
Maitiro ekushandisa sisitimu yemagetsi emvura anogona kutsanangurwa muzvikamu zvinotevera zvinoenderera mberi:
1. Kuchengetedza Simba
Panguva ino, mvura inochengetwa mudziva rakagadzirwa seri kwedhamu. Kureba kwemvura iri mudziva kunogadzira simba rekukwevera pasi, iro ndiro sosi huru yesimba mumagetsi emvura.
2. Kuburitswa kwemvura
Kana simba remagetsi richidikanwa, mvura inoburitswa kubva mudura kuburikidza nepombi yepenstock ichienda kuturbine. Mavharuvhu ekudzora ari papenstock anogona kugadziriswa kuti adzore huwandu hwemvura inoyerera, izvo zvinozodzora simba rinobuda muturbine.
3. Kushandurwa Kwesimba Nematurbines
Mvura inoyerera nepaturbine inoita kuti mashizha eturbine atenderere. Zvichienderana nekugadzirwa kweturbine, simba remuchina rinogona kugadzirwa nenzira dzakasiyana. Turbine yeFrancis, semuenzaniso, inoshandisa kuyerera kwemvura kwakanyanya uye kweaxial kutenderedza mashizha, nepo turbine yePelton ichishandisa ma "water impulses" kuti iwane mhedzisiro imwe chete.
4. Kugadzira Magetsi Nejenareta
Turbine inotenderera inotyaira rotor iri mujenareta. Majenareta anoshanda zvichibva papfungwa ye electromagnetic induction, yakawanikwa naMichael Faraday. Sezvo rotor (magnet) ichitenderera mukati me stator (coil yewaya), simba remagineti rinoshanduka rinogadzira magetsi mu coil. Mugumisiro wacho isimba remagetsi.
5. Kuchinja uye Kugovera
Magetsi anogadzirwa nejenareta anowanzova nemagetsi mashoma, saka anofanira kuwedzerwa netransformer kuti aiparadzire zvakanaka kugrid remagetsi. Kana magetsi awedzerwa, magetsi acho anoparadzirwa kuburikidza nemitsetse yekutumira kusvika asvika kumushandisi wekupedzisira.
Zvakanakira uye Matambudziko eMagetsi eMadziva
Simba remagetsi rinoshandisa mvura rine mabhenefiti akawanda anoita kuti rive rimwe remasimba anonyanya kushandiswazve.
Superiority:
1. Yakachena uye Inogona Kuvandudzwa: Simba remagetsi rinobuda mumvura hariburitse kusvibiswa kwemhepo kana mamwe marara anokuvadza nharaunda. Chero bedzi paine mvura yakakwana, simba iri rinogona kuramba richivandudzwa.
2. Kushanda Nesimba Kwazvo: Masisitimu emagetsi emvura ane simba rakawanda rekushandura simba, kazhinji achisvika pamusoro pe90%.
3. Kukurumidza Kupindura Kudiwa Kwemagetsi: Masisitimu emagetsi emvura anogona kugadzirisa nekukurumidza magetsi aanoshandisa sezvinodiwa, zvichiita kuti ashande zvakanaka mukusangana nekuchinja-chinja kwekudiwa kwemagetsi.
4. Kugara Kwenguva Refu: Zvivakwa zvemadhamu nemagetsi zvinogona kushanda kwemakumi emakore pasina kugadziriswa kwakawanda.
Zvisinei, semamwe matekinoroji, simba remagetsi rinogadzirwa nemvura rinosanganawo nematambudziko akati wandei.
Dambudziko:
1. Kukanganiswa Kwezvakatipoteredza: Kuvakwa kwedhamu kunogona kukanganisa nharaunda dzemunharaunda uye kukanganisa nzvimbo dzinogara zvirimwa nemhuka.
2. Kutamiswa Kwevanhu: Mapurojekiti makuru emadhamu anowanzoda nzvimbo dzakakura dzevhu, izvo zvinogona kukonzera kutamiswa kwevanhu vanogara munzvimbo iyi.
3. Kuvimba neMvura: Kubudirira kwezviteshi zvemagetsi zvinobuda mumvura kunoenderana zvikuru nemvura inonaya. Kusanaya kwemvura kunogona kuderedza kugona kwazvo kugadzira magetsi.
Remangwana reMagetsi Emvura
Pasinei nekutarisana nematambudziko akati wandei, mikana yemagetsi emvura ichiri yakajeka. Kuvandudzwa kwetekinoroji kuri kuramba kuchiitwa kuderedza kukanganisa kwakaipa kwezvakatipoteredza, senge kuvandudzwa kwemadhamu asingakuvadzi nharaunda uye tekinoroji yemvura, iyo ine simba diki rekuchengetedza nharaunda. Uyezve, kubatanidzwa nemamwe masosi esimba rinogona kuvandudzwa, senge simba rezuva nemhepo, kunogona kuita kuti sisitimu yesimba ive yakasimba uye yakavimbika.
Tichitarisana nekuchinja kwemamiriro ekunze uye kudiwa kwesimba remagetsi pasi rose kuri kukura, simba remagetsi rinogadzirwa nemvura rinoramba richiita basa rakakosha sesimba rakachena, rinoshanda zvakanaka, uye rakavimbika. Iyi itsananguro yakadzama yekuti madhamu anogadzira sei simba remagetsi emvura. Nekunzwisisa misimboti yekutanga uye mashandiro ezvikamu zvakakosha, tinogona kunzwisisa zviri nani kukosha kwetekinoroji iyi mukuzadzisa zvinodiwa zvesimba remangwana.
