[ibicuruzwa byumye] amashanyarazi yinganda nyamukuru kubungabunga DQW igice cyumuzenguruko ukoreshwa mubintu bya valve

Kugenzura valve ni valve ikoreshwa mukurinda gusubira inyuma kwitangazamakuru mu miyoboro nibikoresho. Igenzura risohoka ryashyizwe kuri buri muyoboro usohora ubushyuhe bwo hanze muri sisitemu yo kugarura amavuta ya turbine yashizweho. Igikorwa cyayo ni ugufunga isahani ya valve mu buryo bwikora mugihe igice kirimo guta imizigo, kugirango wirinde icyuka kiri kumurongo wicyuma gishyushya hamwe numuyoboro winjira wumuyaga udasubira muri turbine kandi bigatuma turbine yihuta cyane kugirango birinde impanuka.
Kubungabunga indangagaciro nyamukuru
1. Gukuramo igenzura
Kugenzura valve ni valve ikoreshwa mukurinda gusubira inyuma kwitangazamakuru mu miyoboro nibikoresho. Igenzura risohoka ryashyizwe kuri buri muyoboro usohora ubushyuhe bwo hanze muri sisitemu yo kugarura amavuta ya turbine yashizweho. Igikorwa cyayo ni ugufunga isahani ya valve mu buryo bwikora mugihe igice kirimo guta imizigo, kugirango wirinde icyuka kiri kumurongo wicyuma gishyushya hamwe numuyoboro winjira wumuyaga udasubira muri turbine kandi bigatuma turbine yihuta cyane kugirango birinde impanuka.
Igenzura risohoka rya 300MW yatumijwe mu mahanga ni igenzurwa n’ikirere kigenzurwa n’ikirere, imiterere irerekanwa ku gishushanyo, kandi imiterere yintebe igenzurwa n’ikirere irerekanwa kuri iyo shusho. Igizwe ahanini numubiri wa valve, isahani ya valve, shaft, amaboko nibindi. Intebe yo kugenzura ikirere igizwe na piston, blok ya silinderi, inkoni yumuryango nisoko.
Gukuramo bidasubirwaho valve muburyo bwo gufunga gutangira, kurwego rwose rwubushyuhe rutangira, gukuramo bidasubirwaho bidasubirwaho valve pneumatike igenzura ikirere, inkoni ya piston itwara ukuboko kwa rocker kuzunguruka, kugenzura valve shaft amaboko ya plaque plaque axis fungura, isahani ya valve muburyo bwubuntu, mugukuramo igitutu cyamazi kugirango ufungure isahani ya valve, icyuka kinyuze muri valve mumashanyarazi.
Mugihe gikora gisanzwe cyigice, isahani ya valve ibikwa mumwanya usanzwe ufunguye kubera ingaruka zumuvuduko wo gukuramo. Iyo igikoresho kijugunye umutwaro kugirango gihagarare, gukuramo amavuta yumuvuduko ukabije, isahani ya valve biterwa nuburemere bwayo bwihuse gusubira ku ntebe, valve izafungwa, kugirango wirinde gushyushya hamwe na parike mu muyoboro bigaruka kuri turbine, kugirango igere ku nshingano zo kurinda
Imirimo yo kwitegura mbere yo kuvugurura igenzura ryakuweho rifite ibintu bikurikira:
Nyuma yo GUKORA IBIKORWA BIKURIKIRA, KUBURINDA N'AMASOKO n'imbaraga zituruka mu kirere birahagaritswe, guhumeka ikirere hamwe no gusohoka mu cyicaro gikuru cy'ikirere bizarekurwa, ibipapuro bifitanye isano n'inkoni ya piston y'intebe y'ubugenzuzi hamwe na cheque valve. gukurwaho, kandi intebe yubugenzuzi igomba gukurwaho nyuma yo kurekura ibyuma bikosora intebe yubugenzuzi hanyuma bigashyirwa mubwinshi. Noneho, komeza kumurimo ukurikira.
1, gusenyuka kwa valve
.
.
(3) Ihanagura ibinyomoro binini bitwikiriye kandi ukureho impeta nini.
.
(5) Kuraho igiti cya lever na bushing, hanyuma ubishyire.
(6) Kuraho uduce duto hamwe nibindi bikoresho kuruhande rwa shaft yukuboko kwa rocker hanyuma ubishyire.
.
.
(9) Kuraho ukuboko kwa rocker na spol, hanyuma ubishyire.
(10) Kuramo ukuboko kwa rocker na spol, hanyuma ubishyire.
2, kugenzura isuku ya valve
(1) Reba umurongo wa valve kumubiri no kumubiri. Umurongo wa valve ntugomba kugira ibinogo, imyenge hamwe nibisobanuro byubuso bwa kashe ya transvers bigira ingaruka kumikorere ya kashe, kandi bigomba kuba bihuye byuzuye nta nkomyi. Niba inenge zigira ingaruka kumikorere yabonetse, gusya nubundi buryo bwo kuvura bigomba gukorwa.
. Guhuza ibinyomoro hagati yikinyugunyugu nikiganza cya rocker bigomba gukomera, ingingo yo gusudira igomba kuba yuzuye kandi igacika ubusa, kandi ikinyuranyo hagati yikinyugunyugu kinyugunyugu nimpeta yintoki kigomba kuba cyujuje ibisabwa.
.
.
.
. Ubuso bwa kashe ntibushobora kugira inenge zigira ingaruka.
(7) Imfunguzo ninzira zose bigomba gusukurwa kandi bigahuzwa neza.
3, guteranya valve
Mbere yuko valve ishyirwaho, ubuso bwa buri shaft na bushing bigomba gusukwa nifu ya molybdenum disulfide kugeza ibengerana. Inteko igomba gukorwa hakurikijwe ikimenyetso cyiteraniro muburyo butandukanye bwo gusenya. Ingingo zikurikira zigomba kwitabwaho mugikorwa cyo guterana:
. Nyuma yibyo, ibinyomoro bigomba gukomera bigomba gusudira neza hamwe n'ikinyugunyugu.
.
.
.
(5) Ibigega byose bigomba kuvugururwa.
4, gusenyuka kwintebe yo kugenzura
.
.
.
.
(5) Reba kandi usukure intebe y'ubugenzuzi.
1) Reba neza ko urukuta rwimbere rwa silinderi ya piston rugomba kuba rworoshye.
)
3) Reba inkoni ya piston kandi hejuru ya piston igomba kuba yoroshye.
4) Reba hejuru yikimenyetso cyo hejuru, hejuru ya silinderi no guhuza ibice bigomba kuba bitameze neza, kandi bigasukurwa.
(6) Gushiraho intebe yo kugenzura. Kwishyiriraho no guteranya intebe yubugenzuzi bigomba gukorwa ukurikije intambwe ihindagurika yo gusenya, kandi ingingo zikurikira zigomba kwitabwaho:
1) Buri kashe ya O-impeta isimbuzwa ibishya, gusimbuza reberi irwanya ubushyuhe, ubwoko bwa kashe;
2) urukuta rw'imbere rw'umubiri wa silinderi n'ubuso bwa piston bigomba gushyirwaho amavuta ya silicone kugirango bisige amavuta;
3) Nyuma yintebe yo kugenzura ikirere imaze gushyirwaho, inkoni yubusa yinkoni ya piston isuzumwa numwuka ucanye, ugomba kuba wujuje ibyasabwe nuwabikoze, kandi ibikorwa byinkoni ya piston bigomba guhinduka kandi bikomeza nta kintu gifatika.
(7) kugenzura muri rusange. Shyira intebe yo kugenzura kumubiri wa valve, hanyuma uhuze na leveri ya valve, uhuze umuyaga uhuza ikirere, hanyuma ukore igenzura rusange. Ibisabwa:
1) Nyuma yo guterana na cheque yo gukuramo, urugendo rwumuyaga uhindagurika rugomba guhuza ningendo zateganijwe nuwabikoze.
2) Muburyo bwo guhinduranya, ibikorwa rusange bigomba guhora bihindagurika, nta kintu gifatika.
3) Ikimenyetso cyo gufungura valve kigomba kugenzurwa neza, kandi ibikorwa byahinduwe bigomba kugenzurwa hamwe nubushakashatsi bwumuriro. Gufungura no gufunga ibyerekanwa bihuye nibibanza bifatika byerekana valve, kandi kugenzura birarangiye.
Babiri, umutego
1, intangiriro ya
Sisitemu yo kuvoma amashyanyarazi ni igice cyingenzi cya sisitemu yubushyuhe bwa turbine, cyane cyane, ibyuka nyamukuru no gushyushya ibyuka bya turbine ontology hamwe na valve yumuvuduko mwinshi, biha turbine nshya yamashanyarazi hamwe nibindi bikoresho byingenzi byamazi, mumashanyarazi ashyushye, hydrophobique isanzwe ibisabwa mugihe gikwiye, no mubikorwa bisanzwe byigice, kugirango ucike valve kugirango yizewe, nta kumeneka. Niba iyi mitego isohotse, ingaruka kumikorere yikigaragara iragaragara cyane.
Urebye ibi, ishyirwaho rya 300MW yumuriro wa turbine yibice bimwe na bimwe byingenzi byamazi yatumijwe mu mahanga, imiterere yubwoko bwimikorere yo kugenzura gazi yimyanya ibiri yaciwe. Isi ya valve ifite ibyiza byuburyo bworoshye, gufunga neza no kubungabunga. Umubumbe w'isi ufite ibikoresho byo kugenzura pneumatike, bigatuma valve ikora vuba kandi yitabira, kandi irashobora kuzuza neza ibisabwa byikora. Igice cyo kugenzura pneumatike nigicuruzwa cyisosiyete y'Abanyamerika VALTEK, naho igice cyumubiri wa valve nigicuruzwa cyisosiyete y'Abanyamerika ONVAL. Imiterere ya valve irerekanwa mumashusho, kandi imiterere yigikoresho cyo kugenzura ikirere cyerekanwa mubishusho.
