Hydro jenereta ndi makina omwe amasintha mphamvu zomwe zingatheke komanso mphamvu yamagetsi yamadzi kuti ikhale mphamvu yamakina, kenako imayendetsa jenereta kukhala mphamvu yamagetsi.Chigawo chatsopanocho chisanayambe kugwira ntchito, zidazo ziyenera kuyang'aniridwa mosamalitsa zisanayambe kugwira ntchito, apo ayi padzakhala vuto losatha.
1, Kuyang'ana musanayambe unit
(1) Chotsani sundries mu penstock ndi volute;
(2) Chotsani dothi panjira ya mpweya;
(3) Yang'anani ngati pini ya shear ya makina owongolera madzi ndi yotayirira kapena yawonongeka;
(4) Onani ngati pali mitundu yosiyanasiyana mkati mwa jenereta ndi mpweya;
(5) Onani ngati brake air brake imagwira ntchito bwino;
(6) Yang'anani chipangizo chachikulu chosindikizira shaft cha hydraulic turbine;
(7) Chongani mphete wokhometsa, exciter mpweya burashi kuthamanga masika ndi mpweya burashi;
(8) Onani ngati mbali zonse za mafuta, madzi ndi gasi zili bwino.Kaya mulingo wamafuta ndi mtundu wa chotengera chilichonse ndizabwinobwino
(9) Onani ngati malo a gawo lililonse la kazembe ali olondola komanso ngati njira yotsegulira malire ili paziro;
(10) Yesetsani kuyesa valavu ya butterfly ndikuwunika momwe ntchito yosinthira maulendo;
2, Kusamala pa ntchito unit
(1) Makinawo atayamba, liwiro lidzakwera pang'onopang'ono, ndipo silidzawuka kapena kugwa mwadzidzidzi;
(2) Panthawi yogwira ntchito, tcherani khutu ku mafuta a gawo lililonse, ndipo zimatchulidwa kuti malo odzaza mafuta adzadzazidwa masiku asanu aliwonse;
(3) Onani kukwera kwa kutentha kwa ola lililonse, fufuzani phokoso ndi kugwedezeka, ndipo lembani mwatsatanetsatane;
(4) Panthawi yotseka, tembenuzirani gudumu lamanja mozungulira komanso pang'onopang'ono, musatseke chowongolera mwamphamvu kwambiri kuti muteteze kuwonongeka kapena kupanikizana, kenako kutseka valavu;
(5) Potseka nthawi yozizira komanso kutseka kwanthawi yayitali, madzi osonkhanitsidwawo amatsanulidwa kuti ateteze kuzizira ndi dzimbiri;
(6) Pambuyo kutseka kwa nthawi yayitali, yeretsani ndi kusunga makina onse, makamaka mafuta.
3, Shutdown mankhwala pa unit ntchito
Panthawi yogwira ntchito, unityo idzatsekedwa nthawi yomweyo ngati izi zitachitika:
(1) Phokoso la opareshoni ndi lachilendo komanso losavomerezeka pambuyo pa chithandizo;
(2) Kunyamula kutentha kumaposa 70 ℃;
(3) Utsi kapena fungo loyaka kuchokera ku jenereta kapena exciter;
(4) Kugwedezeka kwachilendo kwa unit;
(5) Ngozi pazigawo zamagetsi kapena mizere;
(6) Kutaya mphamvu zothandizira ndi zosavomerezeka pambuyo pa chithandizo.
4, Kukonza makina opangira ma hydraulic
(1) Kukonza mwachizolowezi - kumafunika kuyambitsa, kugwira ntchito ndi kutseka.Chikho cha mafuta a capping chiyenera kudzazidwa ndi mafuta kamodzi pamwezi.Chitoliro chamadzi ozizira ndi chitoliro chamafuta ziyenera kuyang'aniridwa pafupipafupi kuti mafuta azikhala osalala komanso abwino.Chomeracho chiyenera kusungidwa choyera, ndondomeko ya positi idzakhazikitsidwe, ndipo ntchito yopereka ma shift idzachitidwa bwino.
(2) Kusamalira tsiku ndi tsiku - kuyang'anira tsiku ndi tsiku malinga ndi momwe ntchito ikugwirira ntchito, fufuzani ngati madzi atsekedwa kapena atsekeredwa ndi matabwa, udzu ndi miyala, fufuzani ngati njira yothamanga ndi yotayirira kapena yowonongeka, fufuzani ngati madzi ndi mafuta ozungulira tsegulani, ndikulemba.
(3) Kuwongolera ma unit - kudziwa nthawi yosinthira malinga ndi kuchuluka kwa maola ogwirira ntchito, nthawi zambiri kamodzi pazaka 3 ~ 5.Panthawi yokonzanso, ziwalo zowonongeka kwambiri ndi zowonongeka zidzasinthidwa kapena kukonzedwanso ku ndondomeko ya fakitale yoyambirira, monga mayendedwe, mayendedwe oyendetsa, ndi zina zotero pambuyo pa kukonzanso, ntchito yofanana ndi yomwe yakhazikitsidwa kumene idzachitidwa.
5, Zolakwika zamtundu wa hydraulic turbine ndi mayankho awo
(1) Kuwonongeka kwa mita ya Kilowatt
Chodabwitsa 1: chizindikiro cha madontho a kilowatt mita, kugwedezeka kwa unit, kuwonjezeka kwa boti, ndi singano zina za mita.
Chithandizo 1: sungani kuya kwa chubu cholembera kupitirira 30cm pochita opaleshoni kapena kuzimitsa.
Chochitika 2: mita ya kilowatt imatsika, ma mita ena akugwedezeka, chipangizocho chimagwedezeka ndikugwedezeka ndi phokoso lakugunda.
Chithandizo 2: Imitsani makinawo, tsegulani dzenje lolowera kuti muwunikenso ndikubwezeretsanso pini.
Chodabwitsa 3: mita ya kilowatt imatsikira, chipangizocho sichingafikire katundu wonse chikatsegulidwa, ndipo mamita ena ndi abwino.
Chithandizo 3: Imitsani makina kuti muchotse matope kunsi kwa mtsinje.
Chodabwitsa 4: mita ya kilowatt imatsika ndipo unit imatsegulidwa kwathunthu popanda katundu wathunthu.
Chithandizo 4: kuyimitsa makinawo kuti asinthe lamba kapena kupukuta sera ya lamba.
(2) Kugwedezeka kwa Unit, kunyamula vuto la kutentha
Chochitika 1: Chigawo chimagwedezeka ndi cholozera cha kilowatt mita chimasinthasintha.
Chithandizo 1: Imitsani makina kuti muwone chubu ndikuwotchera ming'alu.
Phenomenon 2: chipangizochi chimagwedezeka ndikutumiza chizindikiro cha Bearing Overheating.
Chithandizo 2: yang'anani dongosolo lozizira ndikubwezeretsanso madzi ozizira.
Chodabwitsa 3: ma unit amanjenjemera ndipo kutentha kwake ndikokwera kwambiri.
Chithandizo 3: kubwezeretsanso mpweya kuchipinda chothamanga;.
Chodabwitsa 4: kugwedezeka kwagawo komanso kutentha kwamtundu uliwonse ndi kwachilendo.
Chithandizo 4: kwezani mulingo wamadzi amchira, ngakhale kutseka mwadzidzidzi, ndikumangitsani mabawuti.
(3) Governor oil pressure error
Chodabwitsa: mbale yowunikira yayatsidwa, belu lamagetsi likulira, ndipo mphamvu yamafuta yamagetsi amafuta imatsika mpaka kupsinjika kwamafuta.
Chithandizo: gwiritsani ntchito gudumu lotsegulira lamanja kuti singano yofiyira igwirizane ndi singano yakuda, kudula mphamvu ya pendulum yowuluka, tembenuzirani valavu yosinthira kazembe kuti ikhale pamanja, sinthani ntchito yokakamiza yamafuta pamanja, ndikuyang'anitsitsa ntchito ya unit.Yang'anani makina opangira mafuta opangira mafuta.Ngati sichikanika, yambani mpope wamafuta pamanja.Igwireni pamene mphamvu ya mafuta ikukwera mpaka kumtunda kwa mphamvu ya mafuta ogwira ntchito.Kapena yang'anani chipangizo chopondereza mafuta kuti chiziwotcha mpweya.Ngati mankhwala omwe ali pamwambawa ndi osavomerezeka ndipo kuthamanga kwa mafuta kukupitirirabe, imitsani makinawo ndi chilolezo cha woyang'anira kusintha.
(4) Kulephera kwa bwanamkubwa wokhazikika
Chodabwitsa: bwanamkubwa sangathe kugwira ntchito zokha, servomotor imasinthasintha mosadziwika bwino, zomwe zimapangitsa kuti ma frequency ndi katundu asasunthike, kapena gawo lina la bwanamkubwa limatulutsa mawu osadziwika bwino.
Chithandizo: sinthani nthawi yomweyo kukhala buku lamphamvu yamafuta, ndipo ogwira ntchito sangachoke pamalo owongolera kazembe popanda chilolezo.Onani mbali zonse za bwanamkubwa.Ngati cholakwikacho sichingathetsedwe pambuyo pa chithandizo, perekani kwa woyang'anira zosintha ndikupempha kutseka kwa chithandizo.
(5) Jenereta pamoto
Chodabwitsa: njira yamphepo ya jenereta imatulutsa utsi wandiweyani ndipo imakhala ndi fungo la kutentha.
Chithandizo: Kwezani pamanja valavu yoyimitsa solenoid yadzidzidzi, kutseka chowongolera, ndikusindikiza malire otsegulira singano mpaka ziro.Chosinthira chokomera chikadumpha, tsegulani chopopera chamoto mwachangu kuti uzimitse motowo.Pofuna kupewa kutentha kwa asymmetric shaft ya jenereta, tsegulani pang'ono chowongolera kuti chiwongolerocho chizizungulira mwachangu (10 ~ 20% liwiro lovotera).
Njira zodzitetezera: musagwiritse ntchito madzi kuzimitsa moto pamene chipangizocho sichinagwedezeke ndipo jenereta ili ndi magetsi;Musalowe mu jenereta kuti muzimitse moto;Ndizoletsedwa kugwiritsa ntchito zozimitsa mchenga ndi thovu kuzimitsa moto.
(6) Chipangizocho chimathamanga kwambiri (mpaka 140% ya liwiro lovotera)
Chodabwitsa: mbale yowala ili ndipo lipenga limalira;Katunduyo amatayidwa, kuthamanga kumawonjezeka, gawolo limapanga mawu othamanga kwambiri, ndipo dongosolo losangalatsa limapangitsa kusuntha kokakamiza.
Kuchiza: ngati kuwonjezereka kwachangu chifukwa cha kukana katundu wa unit ndipo bwanamkubwa sangathe kutsekedwa mwamsanga kumalo osanyamula katundu, kutsegula malire a handwheel kudzagwiritsidwa ntchito pamanja kumalo opanda katundu.Pambuyo poyang'anitsitsa mwatsatanetsatane ndi chithandizo, pamene zatsimikiziridwa kuti palibe vuto, woyang'anira zosintha adzalamula katunduyo.Ngati kuthamanga kwambiri chifukwa cha kulephera kwa bwanamkubwa, batani lotsekera liyenera kukanidwa mwachangu.Ngati ikadali yolakwika, valavu yagulugufe iyenera kutsekedwa mwachangu ndikutseka.Ngati chifukwa chake sichidziwika ndipo chithandizo sichinachitike pambuyo poti chigawocho chatha mofulumira, ndizoletsedwa kuyambitsa unit.Zidziwitsidwa kwa wotsogolera chomera kuti afufuze, fufuzani chifukwa chake ndi chithandizo musanayambe gawolo.
