Tsarin sanyaya yana kiyaye zafin aikin janareta a matakin aminci da inganci. Yawanci ana samun wannan ta hanyar zagayawa da na'urar sanyaya ko iska a kusa da sassan janareta. Wasu hanyoyin sanyaya sun haɗa da ruwa, mai, ko tsarin sanyaya. Sanyaya mai kyau yana tabbatar da tsawon rai da inganci ga janareta.
4. Shaft ɗin Injin Turbine-Jenareta
Shaft ɗin injin turbine-generator wani ɓangare ne na injin da ke haɗa injin turbine na ruwa kai tsaye zuwa na'urar juyawa ta janareta. Yayin da ruwa ke gudana da juya injin turbine, wannan shaft ɗin yana aika makamashin injin kai tsaye zuwa na'urar juyawa. Dole ne wannan shaft ɗin ya kasance mai ƙarfi sosai kuma yana iya jure manyan nauyin injin don tabbatar da sauƙin canja wurin makamashi daga injin turbine zuwa janareta.
Aikin Shaft na Injin Turbine-Generator
Babban aikin shaft shine aika makamashi daga injin turbine mai tuƙi zuwa na'urar janareta. Wannan shaft yana juyawa a wani takamaiman gudu, wanda aka ƙaddara ta hanyar yawan kwararar ruwa da ƙirar injin turbine. Daidaito da kula da wannan shaft suna da mahimmanci don hana girgiza mai yawa da tsawaita rayuwar abubuwan da ke da alaƙa.
5. Tsarin Kula da Gudu
Cibiyoyin samar da wutar lantarki na ruwa suna amfani da tsarin sarrafa gudu don kiyaye ingantaccen saurin juyawar injin turbine da rotor. Waɗannan tsarin galibi suna haɗa da amfani da na'urorin sarrafa ruwa ko na lantarki waɗanda ke sarrafa kwararar ruwa zuwa injin turbine.
Aikin Tsarin Sarrafa Gudu
Babban aikin wannan tsarin shine tabbatar da cewa saurin rotor ya kasance iri ɗaya, ba tare da la'akari da bambancin kwararar ruwa ko nauyin wutar lantarki da aka samar ba. Daidaita saurin yana da mahimmanci don tabbatar da cewa mitar wutar lantarki da aka samar ta cika ƙa'idodin da grid ɗin wutar lantarki ke buƙata, yawanci 50 Hz ko 60 Hz.
