Simba remvura ndiro rimwe remasimba ekare uye akavimbika kupfuura mamwe ese muvanhu. Pachinyanya kukosha, ibasa rekushandisa fizikisi yepakutanga, ketani inoenderera mberi yekushanduka kwesimba iyo inoshandisa kutenderera kwemvura yepasi kuti igadzire magetsi. Maitiro aya, ari nyore kwazvo asi akaoma muinjiniya, anoshandura simba remvura riri kufamba kuita simba remagetsi rinopa simba nyika yedu yanhasi. Rwendo rwesimba iri, kubva padonhwe remvura riri kure kuenda kubhabhu remwenje rinopenya, inyaya inonakidza yekushanduka kuburikidza nematanho akasiyana.
Danho 1: Simba Rinogona Kuwanikwa - Dura Rekutanga
Maitiro ese anotanga nesimba rezuva. Zuva rinopisa pamusoro peNyika, zvichiita kuti mvura inobva mumakungwa, mumakungwa, nenzizi itsvuke. Utsi hwemvura uhwu hunoungana kuita makore uye pakupedzisira hunodzokera panyika semvura—mvura kana sinou. Kana mvura iyi yaungana mudziva riri kuseri kwedhamu kana kuti pamusoro pegomo, ine simba guru rekukwevera pasi. Simba iri rinokonzerwa nezvinhu zviviri zvakakosha: huremu hwemvura uye kukwirira kwainogona kudonha. Kana dhamu rakakwirira uye huwandu hwedhamu hwacho hwakakura, simba guru rinochengetwa. Simba iri guru, rakarara, rinofananidzirwa nedziva rakanyarara, ndiro simba rekutanga uye rakakosha kwazvo mucheni yemagetsi emvura. Ndiro mafuta, akamirira kuburitswa.
Danho rechipiri: Kinetic Energy - Torrent Yakasunungurwa
Kana magedhi edhamu akavhurika kana mvura ikaburitswa kubva mukupinda, simba rinochengetwa rinoshanduka nekukurumidza. Richitungamirirwa nekumanikidzwa kukuru kwekoramu yemvura iri pamusoro, mvura inomhanya ichipfuura nemupombi hombe inozivikanwa sepenstock. Painoyerera ichidzika, simba rinokwevera pasi rinoita basa rayo, uye simba rayo rinoshandurwa kuita simba rekinetic—simba rekufamba. Kumhanya kwemvura kunowedzera zvakanyanya painofamba ichidzika mupenstock. Kuchinja uku kwakananga uye kunotongwa nemitemo yekuchengetedza simba; kurasikirwa muhurefu (uye nokudaro simba rinokwanisa) kunoguma nekuwedzera kwakaenzana mukumhanya uye simba rekinetic. Panguva iyo mvura inosvika pasi pepenstock, inenge yava jet ine simba guru, torrent ine simba yakatarisana nebasa rekutyaira turbine.
Danho rechitatu: Simba reMichina - Mwoyo Unotenderera
Mvura inoyerera nekukurumidza zvino yave kuendeswa pamashizha eturbine, inova ndiyo moyo weinjiniya wegwenya. Turbine iyi irotor ine mativi akakombama, akagadzirirwa kubata simba remvura zvinobudirira. Kurova kwemvura pamashizha kunoita kuti turbine itenderere nekukurumidza. Padanho iri rakakosha, simba remagetsi remvura iri kufamba rinotamisirwa kuturbine uye rinova simba remagetsi rinotenderera.
Dhizaini yeturbine yakagadzirirwa mamiriro chaiwo enzvimbo yacho. Kune nzvimbo dzine musoro wakareba, mavhiri ePelton anoshandisa mabhaketi akaita sekapu ayo jet yemvura inorova zvakananga. Kune misoro yepakati, ma Francis turbine, ayo anosangana nekumanikidzwa kwemvura uye kuyerera kwayo, akajairika. Kune mamiriro epasi pemusoro, kuyerera kwakanyanya, ma Kaplan turbine, akafanana nepropeller yengarava, anowanzo shandiswa. Muchiitiko chimwe nechimwe, chinangwa cheturbine ndechekuwedzera kuburitsa simba kubva mumvura, kushandura simba rayo rakatwasuka kana rinotungamirwa nekumanikidzwa kuita kutenderera kwakasimba, kunoramba kuchienderera mberi.
Danho rechina: Simba reMagetsi - Kushandurwa Kwekupedzisira
Turbine inotenderera yakabatana zvakananga neshaft, iyo inotenderedza rotor yejenareta yemagetsi iri muimba yemagetsi. Mukati mejenareta, rotor (electromagnet ine simba) yakakomberedzwa ne stator (seti isingachinji ye copper windings). Zvichienderana nepfungwa ye electromagnetic induction, yakawanikwa naMichael Faraday, kana simba remagineti rikatenderedzwa mukati me coil yewaya, rinoita kuti magetsi afambe muwaya. Saka, simba remagetsi rinotenderera re turbine shaft rinoshandurwa zvisina kuoma kuita simba remagetsi mukati mejenareta.
Simba remagetsi iri idzva riri muchimiro chemagetsi anochinja-chinja (AC). Risati ragona kupfuudzwa kure, magetsi aro anowedzerwa zvakanyanya nematransformer kuderedza kurasikirwa kwesimba panguva yekupfuudzwa. Kubva ipapo, magetsi anopinda mugrid remagetsi, network yakakura yemitsetse inoaendesa kudzimba, mabhizinesi, nemaindasitiri, uko anozopedzisira ashandurwa kuita chiedza, kupisa, uye kufamba.
Kushanda Nesimba Uye Kurasikirwa
Hapana nzira yekushandura simba inoshanda zvizere, uye simba remvura harisi iro rinosiyana. Kurasikirwa kudiki kunoitika padanho rega rega nekuda kwekukweshana (mumabheya epenstock neturbine), kuyerera kwemhepo kwakasimba, kugadzirwa kwekupisa muma windings ejenareta, uye kuramba kuripo muwaya dzemagetsi. Zvisinei, mafekitori emagetsi emazuva ano anoshanda zvinoshamisa, achiwanzo shandura anopfuura 90% yesimba rinowanikwa mumvura kuita simba remagetsi, chiyero chakanyanya kupfuura dzimwe nzira dzakawanda dzekugadzira simba.
Mukupedzisa, kugadzirwa kwesimba remvura inzira yakanaka kwazvo yefizikisi neinjiniya. Ishanduko huru yesimba—kubva pakukwanisa kwakanyarara, kwakachengetwa kumusoro mumakomo, kusvika kusimba remvura inoyerera rakaburitswa, kusvika kusimba remagetsi rinotenderera returbine, uye pakupedzisira kusvika kumagetsi anochinjika anosimudzira budiriro yedu. Ichapupu chakachena, chinodzokororwa, uye chine simba chekugona kwedu kushanda zvinoenderana nemaitiro echisikigo.
