I-turbine yamanzi uhlobo lwemishini ye-turbine emishinini ewuketshezi. Cishe cishe ngo-100 BC, uhlobo lwe-turbine yamanzi - i-turbine yamanzi lwazalwa. Ngaleso sikhathi, umsebenzi oyinhloko kwakuwukushayela imishini yokucubungula okusanhlamvu nokunisela. I-turbine yamanzi, njengedivayisi yomshini enikwe amandla ...Funda kabanzi»

I-Pelton turbine (ehunyushwa futhi ngokuthi i-Pelton waterwheel noma i-Bourdain turbine, isiNgisi: i-Pelton wheel noma i-Pelton Turbine) uhlobo lwe-impact turbine, eyathuthukiswa ngumsunguli waseMelika uLester W. Yathuthukiswa ngu-Alan Pelton. Ama-Pelton turbine asebenzisa amanzi ukugeleza nokushaya i-waterwheel ukuze athole amandla, lapho...Funda kabanzi»

Ijubane lokujikeleza kwama-turbine e-hydraulic liphansi kakhulu, ikakhulukazi kuma-turbine e-hydraulic aqondile. Ukuze kukhiqizwe i-alternating current engu-50Hz, i-hydraulic turbine generator isebenzisa isakhiwo sama-pair amaningi ezigxobo zikagesi. Ku-generator ye-hydraulic turbine ene-revolutions engu-120 p...Funda kabanzi»

I-turbine yamanzi iyi-turbomachinery emishinini yoketshezi. Cishe cishe ngo-100 BC, kwazalwa uhlobo lwe-turbine yamanzi, isondo lamanzi. Ngaleso sikhathi, umsebenzi oyinhloko kwakuwukushayela imishini yokucubungula okusanhlamvu nokunisela. Isondo lamanzi, njengedivayisi yemishini esebenzisa...Funda kabanzi»

Ijeneretha ye-hydro yakhiwe nge-rotor, i-stator, uhlaka, i-thrust bearing, i-guide bearing, i-cooler, i-brake nezinye izingxenye eziyinhloko (bheka Umfanekiso). I-stator yakhiwe kakhulu ngohlaka, i-iron core, i-winding nezinye izingxenye. I-stator core yenziwe ngamashidi ensimbi e-silicon aqoqwe ngokubandayo, angenziwa...Funda kabanzi»

1. Ukuhlolwa kokuchithwa komthwalo kanye nokuchithwa komthwalo kwamayunithi ejeneretha yamanzi kufanele kwenziwe ngokushintshana. Ngemva kokuba iyunithi isilayishiwe okokuqala, ukusebenza kweyunithi kanye nemishini efanele ye-electromechanical kufanele kuhlolwe. Uma kungekho okungavamile, ukuhlolwa kokwenqatshwa komthwalo kungenziwa ngokufaka...Funda kabanzi»

Muva nje, uForster usize amakhasimende aseNingizimu Afrika ngempumelelo ukuthuthukisa amandla afakiwe esiteshini sakhe sikagesi samanzi esingu-100kW abe ngu-200kW. Uhlelo lokuthuthukisa lumi kanje: Ijeneretha ye-turbine ye-kaplan engu-200KW Ikhanda elilinganisiwe 8.15 m Ukugeleza komklamo 3.6m3/s Ukugeleza okuphezulu 8.0m3/s Ukugeleza okuncane 3.0m3/s Kulinganiswe umthamo ofakiwe...Funda kabanzi»

1. Izimbangela zokwakheka kwe-cavitation kuma-turbine Izizathu zokwakheka kwe-turbine ziyinkimbinkimbi. Ukusatshalaliswa kwengcindezi kumgijimi we-turbine akulingana. Isibonelo, uma umgijimi efakwe phezulu kakhulu uma kuqhathaniswa nezinga lamanzi aphansi, lapho amanzi ashesha kakhulu egeleza ngokucindezela okuphansi...Funda kabanzi»

Isitoreji esimpompiwe ubuchwepheshe obusetshenziswa kakhulu futhi obuvuthiwe kakhulu ekugcinweni kwamandla okukhulu, futhi amandla afakiwe eziteshini zamandla angafinyelela kuma-gigawatts. Njengamanje, isitoreji samandla esifakwe esivuthiwe nesinkulu kunazo zonke emhlabeni yi-hydro empompiwe. Ubuchwepheshe besitoreji esimpompiwe buvuthiwe futhi bu...Funda kabanzi»

Ngaphezu kwamapharamitha okusebenza, isakhiwo kanye nezinhlobo ze-hydraulic turbine eyethulwe ezihlokweni ezedlule, kulesi sihloko, sizokwethula izinkomba zokusebenza kanye nezici ze-hydraulic turbine. Uma ukhetha i-hydraulic turbine, kubalulekile ukuqonda ukusebenza kwe-...Funda kabanzi»

Vimbela i-short circuit yesigaba kuya kwesigaba ebangelwa yiziphetho ezikhululekile zama-stator windings. I-stator winding kufanele iboshwe endaweni, futhi ukuhlolwa kwe-slot potential kufanele kuhlangabezane nezidingo. Hlola njalo ukuthi iziphetho ze-stator windings ziyacwila, zikhululekile noma zigugile. Vimbela i-stator winding insulatio...Funda kabanzi»

Akukho ubudlelwano obuqondile phakathi kwemvamisa ye-AC kanye nesivinini senjini yesiteshi sikagesi wamanzi, kodwa kukhona ubudlelwano obungaqondile. Kungakhathaliseki ukuthi hlobo luni lwemishini yokukhiqiza ugesi, idinga ukudlulisa ugesi kugridi ngemva kokukhiqiza ugesi, okungukuthi, ijeneretha idinga...Funda kabanzi»
