Iterambere rikomeje gutera imbere mu ikoranabuhanga rigezweho mu gihugu cyanjye, urwego rw’ibikorwa by’inganda mu gihugu rwanjye rwazamutse cyane, kandi umusaruro w’inganda warazamutse cyane.Nkigikoresho cyibanze mubikorwa byinganda, comprifugal compressor izaba ifite amakosa mugihe ikora.Muri byo, izamuka ry'ubushyuhe bwo gutwara ibihuru ni rusange, bizagira ingaruka ku mikorere rusange ya comprifugal compressor, kandi mubihe bikomeye bizatera ibibazo bikomeye.kunanirwa, bigatuma umusaruro ugabanuka.Kubera iyo mpamvu, iyi nyandiko ikora ubushakashatsi bwimbitse nisesengura ku mpamvu zitera izamuka ry’ubushyuhe bwa centrifugal compressor ifite igihuru, ikanashyira ahagaragara ibitekerezo bitandukanye bifatika hamwe n’ingamba zo guhangana, bigamije kurushaho guteza imbere imikorere y’imyororokere ya centrifugal na gukemura ikibazo kiriho cyo kwihanganira ubushyuhe bwishyamba.Ibyago byinshi byumutekano.
Amagambo y'ingenzi: comprifugal compressor;kubyara igihuru;izamuka ry'ubushyuhe;impamvu nyamukuru;ingamba zifatika zo guhangana
Kugirango ushakishe impamvu zihariye zitera kuzamuka kwubushyuhe bwa centrifugal compressor ifite igihuru, iyi mpapuro ihitamo comprifugal compressor ya L entreprise nkikintu cyubushakashatsi.Compressor ya centrifugal ni 100.000 m³ / h itandukanya ikirere cyo gutandukanya ikirere centrifugal compressor, cyane cyane Umuyaga urahagarikwa, kandi umwuka utumizwa muri 0.5MPa urashobora guhagarikwa kuri 5.02MPa, ugatandukana hanyuma ukajyanwa mubindi bikoresho kugirango ukoreshwe.Mugihe cyibikorwa byo gutangiza uruganda rwa L, compressor ya centrifugal yahuye ninshuro nyinshi kuzamuka kwubushyuhe bwigihuru cyera, kandi burigihe buri gihe izamuka ryubushyuhe ryari ritandukanye, ibyo bikaba byaragize ingaruka kumikorere isanzwe kandi itekanye ya compressor ya centrifugal.Kugirango iki kibazo gikemuke, birakenewe gutahura compressor ya centrifugal, kugirango tumenye icyabiteye kandi dushyireho ingamba zo kurwanya siyanse.
1 centrifugal compressor ibikoresho bitaziguye
Isosiyete ya L 100.000 m³ / h itandukanya ikirere centrifugal compressor ni ubwoko busanzwe bwa compressor ku isoko ryubu, icyitegererezo ni EBZ45-2 + 2 + 2, naho diameter ya shaft ni 120mm.Compressor ya centrifugal igizwe na turbine, parike yihuta na compressor.Ihuza rya shaft hagati ya compressor, umuvuduko wihuta na turbine ya parike ni ihuriro rya diaphragm, kandi gutwara compressor yo mu kirere ni kunyerera, kandi hari ibihuru 5 bitwara byose hamwe..
Centrifugal compressor ikoresha sisitemu yigenga yo gutanga amavuta.Ubwoko bwa compressor amavuta yo gusiga ni amavuta ya N46.Amavuta yo gusiga arashobora kwinjira hagati ya diametre ya shaft hamwe no kwifashisha binyuze mumbaraga zizunguruka za diameter ubwayo.
2 Ibibazo mumikorere ya comprifugal compressor
2.1 Hariho ibibazo bikomeye
Nyuma yivugurura ryuzuye muri 2019, compressor yo mu kirere ishami ryitandukanya ikirere yakoraga neza mugihe cyumwaka umwe, nta kunanirwa gukomeye no gutsindwa kworoheje.Ariko, mu Kwakira 2020, ubushyuhe bwingenzi bushyigikira igihuru cya centrifugal compressor cyazamutse bidasanzwe.Ubushyuhe bwageze kuri dogere selisiyusi 82.1, hanyuma bugabanuka buhoro buhoro nyuma yo kuzamuka, kandi buhagarara kuri dogere selisiyusi 75.Compressor ya centrifugal yahuye nubushyuhe budasanzwe izamuka inshuro nyinshi, kandi ubushyuhe burazamuka buri gihe, cyane cyane nka dogere selisiyusi 80.
2.2 Kugenzura umubiri
Mu rwego rwo gukemura ikibazo cy’izamuka ry’ubushyuhe budasanzwe bwa compressor ya centrifugal, kugira ngo habeho umutekano muke wa comprifugal compressor, uruganda L rwarasenyutse kandi rugenzura umubiri wa comprifugal compressor mu Kuboza, kandi birashobora kugaragara neza ko muri ayo mavuta harimo amavuta. Igice kinini gishyigikira tile Agace Ubushyuhe bwo hejuru bugabanya karubone yoherejwe.Mu gihe cyo kugenzura hanze ya compressor ya centrifugal, wasangaga amakariso abiri yose afite ububiko bwa karubone, kandi imwe mu makariso yatwaraga yari ifite umwobo warohamye nka 10mmX15mm, kandi urwobo rwimbitse rwari nka 0.4mm.
3. Isesengura ryimpamvu zitera ubushyuhe budasanzwe bwa centrifugal compressor ifite igihuru
Dukurikije isesengura ry’abatekinisiye, impamvu nyamukuru zituma izamuka ry’ubushyuhe budasanzwe rya comprifugal compressor ifite igihuru ni ibi bikurikira: (1) Ubwiza bwamavuta.Iyo centrifugal compressor ikora ku muvuduko mwinshi, ubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi bizatera gusaza kwamavuta yo gusiga, bizagira ingaruka mbi ku mavuta yo kwisiga ya centrifugal compressor.Dukurikije imibare yabatekinisiye, burigihe burigihe ubushyuhe buzamutse kuri dogere selisiyusi 10, umuvuduko wo gusaza wamavuta yo gusiga uzikuba kabiri, niba rero imikorere yamavuta yo kwisiga ari mibi, umuvuduko wo gusaza uzihuta cyane mubihe byubushyuhe bwinshi .Igenzura ryakozwe ryamavuta yo gusiga ryasanze ibyinshi mubipimo bitujuje ibyangombwa bisabwa [1] (2) Umubare wamavuta yakoreshejwe.Niba hiyongereyeho amavuta menshi yo gusiga, bizatera imyuka ya karubone mumavuta arenze urugero mugihe cy'ubushyuhe bwinshi, kuko amavuta menshi yo gusiga azatuma amavuta adasubira inyuma, hamwe nuruvange rwamavuta bigoye guhindagurika kandi rufite ubushake bwinshi. guma hafi yigihuru cyera, bikaviramo kugabanuka kwimyenda, kongera kwambara nuburemere bwikariso, bizatuma ubwiyongere budasanzwe bwubushyuhe bwikariso kubera ubushyamirane bukabije.(3) Guhagarika bidasanzwe.Nk’uko iperereza ryakozwe n’abatekinisiye ribitangaza, icyumweru kimwe mbere y’izamuka ry’ubushyuhe budasanzwe bw’igihuru cyera cya centrifugal compressor, habaye ikibazo kinini cyo guhagarika amashyanyarazi muri urwo ruganda, bituma ihagarikwa ridasanzwe rya compressor ya centrifugal.Ihagarikwa ridasanzwe ryatera Imbaraga za axial hamwe nimbaraga zidasanzwe za centrifugal ziyongera ako kanya, bityo bikongera umutwaro wimikorere yibihuru byera, bigatuma ubushyuhe bwamavuta yo kwisiga bwiyongera.
4 Ingamba zifatika zo kuzamuka kwubushyuhe bwa centrifugal compressor ifite igihuru
Mbere ya byose, birakenewe kunoza ubwiza bwamavuta yo gusiga kugirango tumenye neza ko ibipimo byamavuta yo gusiga bishobora kuzuza imikorere yibanze ya compressor ya centrifugal.Amavuta yo gusiga arashobora kunozwa hiyongereyeho antioxydants, anti-friction hamwe na anti-foam mumavuta yo gusiga.Imikorere, irashobora kugera kubisubizo byiza, kugabanya umuvuduko wo gusaza kwamavuta yo gusiga, kugirango wirinde ingaruka zo gusiga za centrifugal compressor zitwara padi kugabanuka kubera umuvuduko ukabije wamavuta yo gusiga, kandi birashobora gukemura neza ikibazo cyubwiyongere budasanzwe bwubushyuhe budasanzwe gutwara amakariso [2].
Icya kabiri, ingano y'amavuta yo kwisiga yakoreshejwe igomba kugenzurwa cyane.Ukurikije imikorere yihariye ya comprifugal compressor, ingano yamavuta yo kwisiga yongeweho igomba kugenzurwa mugihe gikwiye.Amavuta menshi cyane cyangwa make cyane azatera compressor ya centrifugal gukora nabi.Niyo mpamvu, birakenewe kubara neza igipimo cyamavuta yo gukoresha amavuta ya comprifugal compressor no kuzuza amavuta ahagije mugihe.
Ikigeretse kuri ibyo, kubera ko hejuru yubufasha bwikigega cya centrifugal compressor ikozwe mubintu bikomeye bivanze, umuvuduko wo kwambara uratinda cyane, bityo kubitsa karubone kumashanyarazi birashobora gusukurwa na kerosene kugirango bikemure ikibazo cyo kubitsa karubone, bityo gukira Ubuso burangije gusunika bushobora kugera kubisubizo byiza nyuma yo kuvurwa.Byongeye kandi, urebye ikibazo cyibyobo byamavuta bidahagije mumuzinga wogutwara, ingano yo kugaruka kwa peteroli izagabanuka, ibyo bizagira ingaruka kumavuta yo kugaruka.Uburyo bwo guhangayikishwa no gufungura impeta yikurikiranya bwakoreshejwe, kandi umutekinisiye yongeye kubara aho bafungura Umuvuduko, kandi uvugana nuwabikoze, wongera umugozi, kugirango amavuta yo kwisiga arusheho kwinjira neza hejuru yigihuru cyera kugeza gukora firime.
Hanyuma, kugirango iki kibazo gikemuke, amakariso abiri yo hepfo mumashanyarazi mashya akoreshwa mugukuraho umugozi wamavuta, kongera umufuka wamavuta, kongera amavuta yo kwisiga mugihe cyo gukora padi, no gukora imikoranire hagati yububiko. padi na diameter ya shaft birenze., kugirango umenye neza ko aho uhurira hagati yigihuru cyera na diameter ya shaft ishobora kuzuza ibisabwa byujuje ubuziranenge.Muri icyo gihe, uburyo bwo gusiba bwakoreshejwe kugira ngo ukureho ibintu byose byariho kugira ngo ubuziranenge bwujuje ibisabwa [3].
Nyuma yo gufata ingamba zavuzwe haruguru, ikibazo cyizamuka ryubushyuhe budasanzwe bwa comprifugal compressor yakemuwe neza.Nyuma yicyumweru cyo kwipimisha no kwipimisha, ubushyuhe bwigihuru cyera burashobora kugenzurwa hagati ya dogere selisiyusi 50-60, kandi agaciro kanyeganyega kari murwego rwagenwe.Imbere, ingaruka zo guhinduka ziragaragara.
umwanzuro
Mu ncamake, iyi ngingo irasesengura byimazeyo impamvu zitera ubushyuhe bwiyongera rya compressor compressor itwara ibihuru, ikanashyiraho ingamba zifatika, twizeye ko izagira uruhare runini mubijyanye no gufasha mu nganda zigihugu cyanjye.
