Ulwazi lwamandla kagesi

Isiteshi samandla kagesi esipompayo siwubuchwepheshe obusetshenziswa kakhulu futhi obuvuthiwe endaweni yokugcina amandla amakhulu, futhi umthamo ofakiwe wesiteshi sikagesi ungafinyelela ezingeni le-gigawatt. Njengamanje, isiteshi samandla esipompayo esinesilinganiso sokuthuthuka esikhule kakhulu emhlabeni. Isitoreji esipompowe...Funda kabanzi»

Kunezinhlobo eziningi zama-hydro generator. Namuhla, ake sethule i-axial-flow hydro generator ngokuningiliziwe. Ukusetshenziswa kwe-axial-flow hydro generator eminyakeni yamuva ikakhulukazi ukuthuthukiswa kwekhanda lamanzi aphezulu kanye nosayizi omkhulu. Ukuthuthukiswa kwama-axial-flow turbines asekhaya nakho kuyashesha....Funda kabanzi»

Isivinini samaturbines amanzi siphansi, ikakhulukazi i-turbine yamanzi emile. Ukuze kukhiqizwe i-50Hz AC, ijeneretha ye-turbine yamanzi isebenzisa ukwakheka kwezigxobo ezihlukene kazibuthe. Kujeneretha ye-turbine yamanzi enokuphenduka okungu-120 ngomzuzu, amapheya angama-25 ezigxobo kazibuthe ayadingeka. Bheka...Funda kabanzi»

Sekuyiminyaka eyi-111 iChina yaqala ukwakhiwa kwesiteshi sikagesi i-shilongba, okuyisiteshi sokuqala sokuphehla ugesi ngo-1910. Kule minyaka engaphezu kwe-100, kusukela emthanjeni ofakiwe wesiteshi sikagesi sase-shilongba esingu-480 kW kuphela kuya ku-370 million KW manje esikleliswe kuqala emhlabeni, eChina...Funda kabanzi»

I-turbine yamanzi iwuhlobo lwemishini yophephela emshinini owuketshezi. Cishe ngonyaka we-100 BC, i-prototype ye-turbine yamanzi - i-turbine yamanzi iye yazalwa. Ngaleso sikhathi, umsebenzi oyinhloko kwakuwukushayela imishini yokucubungula okusanhlamvu nokunisela. I-turbine yamanzi, njengomshini womshini onikwe amandla ...Funda kabanzi»

I-Pelton turbine (ebuye ihunyushwe ngokuthi: i-Pelton waterwheel noma i-Bourdain turbine, isiNgisi: isondo le-Pelton noma i-Pelton Turbine) iwuhlobo lwe-turbine enomthelela, eyasungulwa umsunguli waseMelika u-Lester W. Yasungulwa ngu-Alan Pelton. Ama-turbine e-Pelton asebenzisa amanzi ukugeleza futhi ashaye isondo lamanzi ukuze athole amandla, ngenkathi ...Funda kabanzi»

Isivinini sokujikeleza sama-hydraulic turbines siphansi uma kuqhathaniswa, ikakhulukazi kuma-vertical hydraulic turbines. Ukuze ukhiqize amandla ashintshayo angu-50Hz, ijeneretha ye-hydraulic turbine isebenzisa ukwakheka kwamapheya amaningi ezigxobo kazibuthe. Okwejeneretha ye-hydraulic turbine ene-revolutions engu-120 p...Funda kabanzi»

I-turbine yamanzi iyi-turbomachinery emshinini owuketshezi. Emuva nje cishe nge-100 BC, i-prototype ye-turbine yamanzi, isondo lamanzi, yazalwa. Ngaleso sikhathi, umsebenzi oyinhloko kwakuwukushayela imishini yokucubungula okusanhlamvu nokunisela. Isondo lamanzi, njengomshini osebenzisa i-wat...Funda kabanzi»

Ijeneretha ye-Hydro yakhiwa i-rotor, i-stator, ifreyimu, i-thrust bear, i-guide bear, i-cooler, ibhuleki nezinye izingxenye eziyinhloko (bheka Umfanekiso). I-stator ngokuyinhloko yakhiwe ifreyimu, i-iron core, i-winging nezinye izakhi. I-stator core yenziwe ngamashidi ensimbi e-silicon egoqwe abandayo, angenziwa ...Funda kabanzi»

1. Ukuhlolwa kokucishwa kukagesi kanye nokucishwa kukagesi kwamayunithi aphehla ugesi kuzokwenziwa ngokushintshana. Ngemuva kokuthi iyunithi ilayishiwe ekuqaleni, ukusebenza kweyunithi kanye nezinto ezifanele ze-electromechanical kuzobhekwa. Uma kungekho okungavamile, ukuhlolwa kokwenqatshwa komthwalo kungenziwa ngokushesha...Funda kabanzi»

1. Izimbangela ze-cavitation kuma-turbines Izizathu ze-cavitation ye-turbine ziyinkimbinkimbi. Ukusatshalaliswa kwengcindezi kumgijimi we-turbine akulingani. Isibonelo, uma umgijimi efakwe phezulu kakhulu ngokuhlobene nezinga lamanzi angezansi, lapho amanzi anesivinini esikhulu egeleza ngomshini ophansi...Funda kabanzi»

Isitoreji esipompayo siwubuchwepheshe obusetshenziswa kakhulu futhi obuvuthiwe endaweni yokugcina amandla amakhulu, futhi umthamo ofakiwe weziteshi zikagesi ungafinyelela kuma-gigawatts. Njengamanje, isitoreji samandla esivuthiwe nesinkulu kunazo zonke esifakiwe emhlabeni yi-hydro. Ubuchwepheshe be-pumped storage buvuthiwe futhi busezingeni...Funda kabanzi»
