Bukatun Zazzabi na Generator da sanyaya

A matsayin tushen wutar lantarki na gaggawa, janareta na diesel yana buƙatar yin aiki na dogon lokaci ba tare da tsayawa ba yayin amfani. Tare da irin wannan babban kaya, yanayin zafi na janareta ya zama matsala. Don kiyaye kyakkyawan aiki mara yankewa, dole ne a kiyaye zafin jiki a cikin kewayon da za a iya jurewa. A cikin wannan, don haka ya kamata mu fahimci bukatun zafin jiki da hanyoyin sanyaya.

1. Bukatun zafin jiki

Dangane da nau'ikan rufi daban-daban na janareta na dizal, buƙatun hawan zafin jiki sun bambanta. Gabaɗaya, zafin jiki na iskar stator, jujjuyawar filin, ƙarfin ƙarfe, zoben tattarawa suna kusan 80 ° C lokacin da janareta ke aiki. Idan ya zarce, shine Hawan zafin jiki yayi yawa.

2. Sanyi

Daban-daban iri da iyawar janareta suna da yanayin sanyaya daban-daban. Koyaya, matsakaicin sanyaya da ake amfani dashi shine iska, hydrogen, da ruwa. Ɗauki janareta na aiki tare da injin turbine a matsayin misali. An rufe tsarin sanyaya, kuma ana amfani da matsakaicin sanyaya a wurare dabam dabam.

① sanyaya iska

Sanyaya iska yana amfani da fanka don aika iska. Ana amfani da iska mai sanyi don busa ƙarshen iskar janareta, injin janareta da rotor don watsar da zafi. Iskar sanyi tana ɗaukar zafi kuma ta juya zuwa iska mai zafi. Bayan an haɗa su, ana fitar da su ta hanyar iskar iskar baƙin ƙarfe kuma a sanyaya ta mai sanyaya. Daga nan sai a aika da iskar da aka sanyaya zuwa janareta don sake yin amfani da fanfo don cimma manufar yaɗuwar zafi. Matsakaici da ƙananan janareta na aiki tare gabaɗaya suna amfani da sanyaya iska.

② Hydrogen sanyaya

Ruwan sanyaya hydrogen yana amfani da hydrogen a matsayin matsakaicin sanyaya, kuma aikin watsar da zafi na hydrogen ya fi na iska. Alal misali, mafi yawan masu samar da turbo suna amfani da hydrogen don sanyaya.

③ sanyaya ruwa

Ruwa sanyaya rungumi dabi'ar stator da rotor biyu ruwa na ciki sanyaya hanyar. Ruwan sanyi na tsarin ruwa na stator yana gudana daga tsarin ruwa na waje ta hanyar bututun ruwa zuwa zoben shigar ruwa da aka sanya a kan stator, sannan kuma yana gudana zuwa gaɗaɗɗen ta cikin bututun da aka rufe. Bayan shayar da zafi, ana tattara shi ta bututun ruwa da aka keɓe zuwa zoben fitar da ruwa da aka sanya akan firam. Sannan ana fitar da shi a cikin tsarin ruwa a wajen janareta don sanyaya. Sanyaya tsarin ruwa na rotor ya fara shigar da tallafin shigar ruwa wanda aka sanya a gefen shaft ɗin ƙarshen abin motsa jiki, sa'an nan kuma ya kwarara zuwa cikin tsakiyar rami na jujjuyawar, yana gudana tare da ramukan meridional da yawa zuwa tankin tattara ruwa, sannan ya gudana zuwa coils ta cikin insulating tube. Bayan ruwan sanyi ya sha zafi, sai ya shiga cikin tankin fita ta cikin bututun da aka keɓe, sannan ya kwarara zuwa mashin ɗin ta hanyar ramin magudanar ruwa da ke gefen wajen tankin ɗin, sannan babban bututun mai fitar da bututun ya jagorance shi. Tun da aikin watsar da zafi na ruwa ya fi na iska da hydrogen girma, sabon babban janareta gabaɗaya ya ɗauki sanyaya ruwa.
