Ingano yo gusaba hamwe nibisabwa bya tekiniki ya power power (IV)

Gukoresha amashanyarazi, ni ukugabanya abakozi imbaraga zumurimo kandi bikenewe mubikorwa bibi, valve yamashanyarazi igizwe na moteri, agasanduku k'ibikoresho n'umubiri, mubisanzwe mubikorwa bikunze kubera ibintu nko kunyeganyega, ubushyuhe, gufunga gusaza akenshi amavuta atandukanye ikibazo cyo kumeneka, agasanduku k'ibikoresho kumeneka kwangiza ibidukikije ntabwo gusa hari ingaruka zishobora guhungabanya umutekano. Amasomo y'impanuka z'umutekano yatewe no "kwiruka, kwiruka, gutonyanga no kumeneka" y'ibikoresho nabyo bihora byitabwaho mubikorwa byo gucunga ibikoresho. Agasanduku k'ibikoresho byamavuta yamenetse, kubera imiterere yibikoresho, gukoresha ibidukikije, akazi gahoraho nibindi bihe, mubisanzwe hamwe no gusimbuza ibice, hamwe no gusimbuza ingamba zo gufunga
Impamvu nisesengura ryamavuta yamenetse mumashanyarazi ya valve yamashanyarazi
Gukoresha amashanyarazi, ni ukugabanya abakozi imbaraga zumurimo kandi bikenewe mubikorwa bibi, valve yamashanyarazi igizwe na moteri, agasanduku k'ibikoresho n'umubiri, mubisanzwe mubikorwa bikunze kubera ibintu nko kunyeganyega, ubushyuhe, gufunga gusaza akenshi amavuta atandukanye ikibazo cyo kumeneka, agasanduku k'ibikoresho kumeneka kwangiza ibidukikije ntabwo gusa hari ingaruka zishobora guhungabanya umutekano. Amasomo y'impanuka z'umutekano yatewe no "kwiruka, kwiruka, gutonyanga no kumeneka" y'ibikoresho nabyo bihora byitabwaho mubikorwa byo gucunga ibikoresho. Bitewe no kugabanuka kwimiterere yibikoresho, ibidukikije bikora hamwe nuburyo bukomeza bwo gukora, amavuta yamenetse yisanduku yibikoresho biragoye kwihuta kandi neza mubisubizo gakondo byo gusimbuza ibice no gufunga.
Ubushobozi bwose bwashyizwemo uruganda rwamashanyarazi rwa Huaneng ni 2060MW, kandi uburyo bwo kwagura ibice 2 × 1000MW byabitswe mugice cya gatatu. Igice cya 2 × 350MW cyumushinga wambere nicyiciro cyatumijwe mu mahanga cyateguwe hamwe nu Bushinwa n’ibihugu by’amahanga. Guhitamo ibikoresho nyamukuru byateye imbere, gahunda irahuzagurika, igice gifite ubukungu buhanitse, kandi umurimo wo kurinda uratunganye. Ni uruganda rukora amashanyarazi rugezweho rufite urwego rwo hejuru rwikora mu Bushinwa. Icyiciro cya kabiri cyumushinga ni 2 × 680MW y’imbere y’imbere y’amakara akoreshwa n’amakara, kubaka icyarimwe ibikoresho byo mu mazi yo mu nyanja.
Ikibanza cyo gukoresha ibikoresho bya Carbone nanopolymer mugutunganya imyanda yimyenda iva muri Soley Industry
Uburyo bwo gukora kurubuga nuburyo bukurikira:
1, sukura ibice byamavuta yamenetse, usukure hafi yibice bisohoka, kuburyo byerekana ibara ryibanze ryibanze, ibice bya bolt nabyo bivura hejuru;
2, gusukura, ibisabwa byo kuvura hejuru bisukuye, byumye, bikomeye, bikabije;
3. Kuvanga ibikoresho bya SD2240 kugirango ushireho ibice bitemba mumwanya muto kugeza igihe bitamenetse;
4. Nyuma yubuso bwibikoresho bimaze gukira, ibikoresho byongeye gutwikirwa na SD7111C. Ibikoresho birakira kandi birasanwa.
Ingano yo gusaba hamwe nibisabwa bya tekiniki yumuriro wamashanyarazi (iv) Ubushyuhe ntarengwa bwa serivisi yibice byikigero ntigishobora gutekereza ko ubushyuhe bwemewe bwo guteka mugihe gikora gisanzwe, kandi agaciro ko gutandukana kugomba gukurikiza ibiteganijwe na SDGJ6 -1990. Hagomba kwitonderwa gushushanya ibikoresho byuma mubihe bikurikira: ibyuma bya Chromium-aluminium (kugeza 0,6%) bikoreshwa mugihe kirekire hejuru ya 525 ℃. Umubiri wa valve hamwe numuyoboro uhuza weld ni umurima wo gusudira, umuyonga wacyo wanyuma utunganijwe nishami rishinzwe gukora valve. Uburyo bwo gusudira buto ya valve yumurongo wumurongo wanyuma bigomba kuba intoki arc gusudira, hydrogen arc gusudira hiyongereyeho gusudira intoki arc cyangwa ubundi buryo bwo gusudira bujuje ibisabwa mugusuzuma inzira.
