Zisebenza njani iimpompo zamanzi elanga?

Iimpompo zamanzi elangazikhula ekudumeni njengendlela ezinzileyo nengabizi kakhulu yokuhambisa amanzi acocekileyo eluntwini nakwiifama.Kodwa zisebenza njani iimpompo zamanzi elanga?

Iimpompo zamanzi elanga zisebenzisa amandla elanga ukumpompa amanzi kwimithombo engaphantsi komhlaba okanye kumadama ukuya phezulu.Ziquka izinto ezintathu eziphambili: iipaneli zelanga, iimpompo kunye nezilawuli.Makhe sijonge ngakumbi icandelo ngalinye kunye nendlela asebenzisana ngayo ukubonelela ngonikezelo lwamanzi oluthembekileyo.

Eyona nxalenye ibalulekileyo yenkqubo yempompo yamanzi elanga yiiphaneli yelanga.Iiphaneli zenziwe ngeeseli ze-photovoltaic eziguqula ukukhanya kwelanga ngqo kumbane.Xa ukukhanya kwelanga kubetha ipaneli yelanga, iiseli ze-photovoltaic zivelisa i-current ngqo (DC), ethi ithunyelwe kumlawuli, olawula ukuhamba kwangoku kwimpompo.

Iimpompo zinoxanduva lokuhambisa amanzi ukusuka kwindawo ukuya apho afuneka khona.Kukho iintlobo ngeentlobo zeempompo ezifumanekayo kwiinkqubo zokumpompa amanzi elanga, kuquka iimpompo ze-centrifugal kunye neempompo ezingaphantsi kwamanzi.Ezi mpompo zenzelwe ukuba zisebenze kwaye zomelele, zivumela ukuba ziqhubeke nokusebenza nakwiindawo ezikude okanye ezinzima.

Ekugqibeleni, umlawuli usebenza njengobuchopho bokusebenza.Iqinisekisa ukuba impompo isebenza kuphela xa kukho ukukhanya okwaneleyo kwelanga ukuyinika amandla ngokufanelekileyo, kwaye ikhusela impompo kumonakalo onokuthi ubangelwa kuxinzelelo oluphezulu okanye ngaphezulu.Abanye abalawuli baquka iimpawu ezifana nokubeka iliso kude kunye nokungena kwedatha, okuvumela abasebenzisi ukuba balandele ukusebenza kwenkqubo kwaye benze naluphi na uhlengahlengiso oluyimfuneko.

Ke, zonke ezi zixhobo zisebenzisana njani ukumpompa amanzi kusetyenziswa amandla elanga?Inkqubo iqala ngeepaneli zelanga ezifunxa ukukhanya kwelanga kwaye ziguqule zibe ngumbane.La mandla ke athunyelwa kumlawuli, ogqiba ukuba kukho amandla aneleyo okuqhuba impompo.Ukuba iimeko zivuma, isilawuli sivula impompo, ethi ke iqalise ukumpompa amanzi ukusuka kumthombo kwaye iwase kwindawo yayo, nokuba yitanki yokugcina, inkqubo yokunkcenkceshela okanye umkhombe wemfuyo.Ngethuba nje kukho ukukhanya kwelanga okwaneleyo ukunika amandla impompo, iya kuqhubeka isebenza, ibonelela ngokubonelelwa kwamanzi rhoqo ngaphandle kwesidingo samafutha emveli okanye umbane wegridi.

Kukho iingenelo ezininzi zokusebenzisa inkqubo yepompo yamanzi elanga.Okokuqala, aziyikhathalelanga imeko-bume ngenxa yokuba azikhuphi iigesi zegreenhouse kwaye zixhomekeke kumandla ahlaziyekayo.Ukongezelela, amaxabiso aphantsi njengoko anokunciphisa kakhulu okanye aphelise iindleko zombane kunye nepetroli.Iimpompo zamanzi elanga nazo zifuna ukugcinwa okuncinci kwaye ziphile ixesha elide, zibenza isisombululo sonikezelo lwamanzi oluthembekileyo kunye noluzinzileyo kwiindawo ezikude okanye ezingekho kwigridi.
