Imithombo Yamanzi, Ukubekwa Kwawo, Ukuwalawula kanye Nokuwa Pompa

Imithombo Yamanzi

Woke amanzi afika ngaphezulu kwehlabathi ngendlela eihlukileko ezifana nesithwathwa, izulu,isinanja,nanyana umbethe. Kunemithombo emibile eqakathekileko esiwusebenzisako kwezolimo kanye nalokha sizisebenzisela wona ekhaya, okumamanzi akhamba ngaphezulu kwehlabathi ezangaphezulu ehlabathini avela emadamini nemilanjeni abe ayokufika lapha asetjenziswa khona nanyana emanzini akhamba ngaphasi kwehlabathi akhamba ngokusebenzisa amaaquifers kanye nama-fissures ehlababathini kuze kufike lapha afika khona ebantwini abazembela ama-boreholes nanyana umthombo.

Ukubekwa Kwamanzi

Amanzi abekwa emadamini ngemva kwalokho asetjenziselwe ukuthelelela. Ukuwaloba nge-evaporation kungaba kukhulu nange amadamu amakhulu. Amanzi aphuma ngaphasi ehlabathini angapontjwa asuka emamitheni alikhulu ngaphasi kwamadamu aya emadamini ayokuthelelela iintjalo ngokusebenzisa ama-aquifers angaphasi kwehlabathi. Amanzi angaphasi kwehlabathi angafika emthonjeni. Ngesinye isikhathu amadamu wemvelo avela emthonjeni nanyana lapha kurhatjheka khona imilambo nanyana endaweni esipara.

Ukulawula Amanzi

Ukulawula amanzi ngokusebenzisa amaforo avuliweko, amaphayiphu nanyana amakhanali aya lapha amanzi abekwa khona kuthi ngemva kwalokho asetjenziswe. Amanzi kuncono akhanjiswe emaphayiphini kunokobana avunyelwe kobana ageleze eemforweni ezivulekileko nanyana kumakhanali ngombana aqedwa kutjhisa kwelanga /-evaporation nanyana kuvuzela ehlabathini.

UkuwaPompa

Iimpopo ezinengi zokuthelelela zisebenzisa igezi, ipetroli kanye nedizela.
Kunemihlobo emibili eqakathekileko yempopo,i-centrifugal pumps kanye ne-displacement pumps.
I-Displacement pumps isebenza ngokobana amanzi angene empopini ngesango lepompi adlulele ngelawini ngekani, eliqindezela amanzi ukusuka elawini abe afike lapha aphuma khona.Amanzi eselawini alawulwa mavelvu amabili aqale endaweni ezihlukileko angabuyiko. Amandla lawo angenziwa mihlobo eminengi yamandla efana nedizeli yomoya, ipetroli nanyana lokha nakusetjenziswa i-hydraulic pump kusetjenziswa i-kinetic energy eyenziwe mamanzi ngokwawo.
Lokha nakuthelelelwako kusetjenziswa i-centrifugal pump. I-centrifugal pump ine-impeller enamakomitji athola amani hlangana nendawo azombeleza ilawu ngokusebenzisa i-centrifugal force esiwa hlangana nendawo ye- impeller isiwa phambili ukuya ekugcineni kwayo ibese iragelwa empompini ebunjiweko ikhiphe amanzi ephayiphini.
