Ingufu zo gushyigikira VS Ingufu zo gushyiramo imbaraga

 

1. Ibyuma bishyigikira ibyuma n'imikorere yabyo

Ibyuma bishyigikirani ingenzi mu turbine y'umwuka. Ingufu nyamukuru yitwa kandi ingufu ya radial.

Inshingano yayo ni ugushyigikira uburemere bwose bwa rotor n'imbaraga za centrifugal ziterwa no kudahuza kwa rotor, no kumenya aho rotor iri mu cylinder ihagaze neza. Kubera ko buri feri igomba kwihanganira imizigo myinshi kandi shaft journal ikazenguruka ku muvuduko mwinshi, feri za turbine y'umwuka zikoresha sliding bearings zo mu bwoko bwa journal hashingiwe ku ihame ryo gusiga amavuta. Filimi y'amavuta itera amavuta ikora hagati ya shaft journal na bearing, igatera friction y'amazi kugira ngo turbine y'umwuka ikore neza kandi ihamye.

 

Hari ubwoko bune bw'ingenzi bw'udupira tw'ingenzi twa turbine y'umwuka: udupira tw'inkingi z'umurambararo, udupira tw'inkingi z'umurambararo, udupira tw'inkingi z'amavuta atatu, n'udupira tw'inkingi z'umurambararo dutinze.

 

2. Imikorere yaIbyuma byo gushyiramo imbaraga

Akamaro k'icyuma gitera imbaraga ni ukwihanganira imbaraga zifata icyuma gitera imbaraga mu gihe cy'ikoreshwa no kumenya no kubungabunga aho icyuma gitera imbaraga giherereye.

 

Ibyuma byo gupfunyika bishobora gushushanywa nk'ibice byigenga cyangwa bigahuzwa n'ibyuma byo gupfunyika mu gice kimwe, cyitwa icyuma cyo gupfunyika gihujwe (cy'imbaraga zo gupfunyika).

Mu miterere, zishobora kuba zifite ibice byinshi cyangwa se zimeze nk'ibice; ubu, ubwoko bukoreshwa cyane ni icyuma gikozwe mu buryo bwa sector. Ibice byacyo by'ingenzi birimo udupira two gukora, udupira tudakora, udupira two guhuza, n'impeta zo gushyiramo.

 

Ku mpande zombi za disiki yo gukurura, hashyizweho udupapuro icumi kugeza kuri cumi na tubiri dukora n'utudakora. Buri dupapuro dushyirwa ku mpande yo gushyiramo; udupapuro dukora dufite umuvuduko w'imbere wa rotor, naho udupapuro tudakora dufite umuvuduko w'inyuma.

 

Udupira tudakora tw’icyuma gitera imbaraga ntabwo dukunze kugira imbaraga. Ariko, iyo umutwaro wa turbine ugabanutse mu buryo butunguranye, nko mu gihe umutwaro wanze, turbine ishobora guhura n’imbaraga zitera imbaraga mu cyerekezo gitandukanye n’umuvuduko w’umwuka. Muri iki gihe, udupira tudakora, binyuze mu icyuma cyazo cy’amavuta gifite ishusho nk’iy’agace, bifasha kuringaniza iki gice cy’imbaraga zitera imbaraga, bikarinda kwimuka cyane kwa turbine no kwirinda kugongana no kwangirika hagati y’ibice bigenda n’ibidahagarara.

 

3. Ibipimo byo kugenzura TSI mu gihe cyo gukora turbine y'umwuka

1. Ubushyuhe bw'icyuma gishyigikira icyuma kiri munsi ya 105°C.

2. Ubushyuhe bw'icyuma gikoresha imbaraga < 100°C.

3. Ubushyuhe bw'isura ikora ku bipimo byo gukururaho <100°C.

4. Ubushyuhe bwo mu maso budakora bw'udupira two gusukamo ibintu <100°C.

5. Kwimura umurongo w'imbere < 1.2 mm na > -0.6 mm.

6. Kwagura silinda ifite umuvuduko mwinshi n'uringaniye < 6 mm na > -3 mm.

7. Gutemba kw'umupfundikizo w'inyuma < 0.05 mm, gutemba kw'imirongo < 125μm.

8. Guhindagurika kw'utubumbe tw'ibumoso n'iburyo bigomba kuba bito.
