Ezinye izinkinga zizokwenzeka uma ijeneretha yesitimu isetshenziswa isikhathi eside kakhulu. Ngakho-ke, sidinga ukunaka umsebenzi wokulungisa ohambisanayo lapho sisebenzisa i-generator ye-steam ekuphileni kwansuku zonke. Namuhla, ake sixoxe nawe mayelana nezindlela zokunakekela zansuku zonke nemijikelezo yokunakekela amajeneretha omusi.
1. Ukugcinwa okujwayelekile kwejeneretha yesitimu
1.Igeji yezinga lamanzi
Hlanza imitha yezinga lamanzi okungenani kanye ngeshifu ngayinye ukuze ugcine ipuleti lengilazi elisezingeni lamanzi lihlanzekile, qinisekisa ukuthi ingxenye ebonakalayo yemitha yezinga lamanzi icacile, nezinga lamanzi lilungile futhi lithembekile. Uma i-gasket yengilazi ivuza amanzi noma isitimu, qinisa noma ubuyisele isigcwalisi ngesikhathi.
⒉Izinga lamanzi ebhodweni
Ibonakala ngohlelo lokulawula ukunikezwa kwamanzi okuzenzakalelayo, futhi ukulawulwa kwezinga lamanzi kuthatha isakhiwo se-electrode. Ukuzwela nokuthembeka kokulawulwa kwezinga lamanzi kufanele kuhlolwe njalo.
3. Isilawuli sokucindezela
Ukuzwela nokuthembeka kwesilawuli sokucindezela kufanele kuhlolwe njalo.
4. Isilinganiso somfutho
Ukuthi igeyiji yokucindezela isebenza kahle yini kufanele ihlolwe njalo. Uma igeji yokucindezela itholakala ukuthi yonakalisiwe noma ingasebenzi kahle, isithando somlilo kufanele sivalwe ngokushesha ukuze silungiswe noma sishintshwe. Ukuqinisekisa ukunemba kwegeji yokucindezela, kufanele ilinganiswe okungenani kanye njalo ezinyangeni eziyisithupha.
5. Ukukhishwa kwendle
Ngokuvamile, amanzi okuphakelayo aqukethe amaminerali ahlukahlukene. Ngemva kokuba amanzi okuphakelayo engene ejeneretha yesitimu futhi ashise futhi ahwamuke, lezi zinto zizoncipha. Lapho amanzi e-boiler egxiliwe ngezinga elithile, lezi zinto zizohlala ebhodweni futhi zenze isikali. Lapho ukuhwamuka kukhudlwana, kuyanda ukuhwamuka. Uma umsebenzi uqhubeka isikhathi eside, intlenga iyakhula. Ukuze kuvikelwe izingozi ze-steam generator ezibangelwa isikali kanye ne-slag, izinga lokuhlinzekwa kwamanzi kufanele liqinisekiswe futhi i-alkalinity yamanzi e-boiler kufanele inciphise; ngokuvamile lapho i-alkalinity yamanzi kubhayela inkulu kuno-20 mg okulingana/ilitha, indle kufanele ikhishwe.
2. Umjikelezo wokugcinwa kwe-Steam generator
1. Khipha indle nsuku zonke
Ijeneretha yesitimu idinga ukukhanywa nsuku zonke, futhi ukushaywa ngakunye kudingeka kwehliswe ngaphansi kwezinga lamanzi lejeneretha yesitimu.
2. Ngemva kokuba okokusebenza kusebenze amasonto angu-2-3, izici ezilandelayo kufanele zigcinwe:
a. Yenza ukuhlola okuphelele kanye nokukalwa kwemishini yokulawula okuzenzakalelayo namathuluzi. Izisetshenziswa ezibalulekile zokubona kanye nemishini yokulawula okuzenzakalelayo efana nezinga lamanzi nokucindezela kufanele kusebenze ngokujwayelekile;
b. Hlola inqwaba yamapayipi okuhambisa kanye nesilondolozi samandla, bese ususa noma yikuphi ukunqwabelana kothuli uma kukhona. Uma kungekho ukunqwabelana kothuli, isikhathi sokuhlola singanwetshwa sibe kanye ngenyanga. Uma kungakabi khona ukunqwabelana kothuli, ukuhlolwa kunganwetshwa kube kanye njalo ezinyangeni ezi-2 kuya kwezi-3. Ngesikhathi esifanayo, hlola ukuthi ingabe kukhona ukuvuza ekuhlanganyeleni kokushisela kokuphela kwepayipi. Uma kukhona ukuvuza, kufanele kulungiswe ngesikhathi;
c. Hlola ukuthi izinga likawoyela lesigubhu kanye nesihlalo esinefeni eliwuhlaka elijwayelekile lijwayelekile, futhi ipayipi lamanzi okupholisa kufanele libe bushelelezi;
d. Uma kukhona ukuvuza ezilinganisweni zamanzi, ama-valve, ama-flange amapayipi, njll, kufanele alungiswe.
3. Ngemva kwezinyanga ezi-3 kuya kweziyi-6 zokusebenza kwe-jeneretha yesitimu, i-boiler kufanele ivalwe ukuze ihlolwe futhi igcinwe kahle. Ngaphezu komsebenzi ongenhla, umsebenzi olandelayo wokulungisa i-steam generator nawo uyadingeka:
a. Izilawuli zezinga lamanzi zohlobo lwe-Electrode kufanele zihlanze ama-electrode ezinga lamanzi, futhi amageji okucindezela asesetshenziswe izinyanga eziyisi-6 kufanele alinganiswe kabusha;
b. Vula isembozo esiphezulu se-economizer ne-condenser, susa uthuli oluqoqwe ngaphandle kwamashubhu, susa izindololwane, futhi ususe ukungcola kwangaphakathi;
c. Susa isikali nodaka ngaphakathi kwesigubhu, ishubhu eludongeni olupholile ngamanzi kanye nebhokisi lesihloko, ugeze ngamanzi ahlanzekile, futhi ususe umlotha nomlotha wesithando odongeni olupholile ngamanzi kanye nomlilo womlilo wesigubhu;
d. Hlola ingaphakathi nangaphandle kwejeneretha yesitimu, njengamashiseli ezingxenye ezithwala ukucindezela nokuthi ingabe akukho ukugqwala ngaphakathi nangaphandle kwamapuleti ensimbi. Uma kutholakala amaphutha, kufanele alungiswe ngokushesha. Uma iphutha lingelikhulu, lingashiywa ukuze lilungiswe ngesikhathi sokuvalwa okulandelayo kwesithando somlilo. Uma kutholakala noma yini esolisayo kodwa ingathinti ukuphepha komkhiqizo, kufanele kwenziwe irekhodi ukuze lisetshenziswe esikhathini esizayo;
e. Hlola ukuthi ingabe ukugoqa kwesiphephetha-moya esifakiwe kujwayelekile kanye nezinga lokuguga kwe-impeller negobolondo;
f. Uma kunesidingo, susa udonga lwesithando somlilo, igobolondo langaphandle, isendlalelo se-insulation, njll ukuze uhlolwe ngokugcwele. Uma kutholakala noma yimuphi umonakalo omkhulu, kufanele ulungiswe ngaphambi kokuqhubeka nokusetshenziswa. Ngesikhathi esifanayo, imiphumela yokuhlolwa kanye nesimo sokulungisa kufanele kugcwaliswe encwadini yokubhaliswa kobuchwepheshe be-steam generator.
4. Uma ijeneretha yesitimu isisebenze isikhathi esingaphezu konyaka owodwa, kufanele kwenziwe lo msebenzi wokulungisa olandelayo:
a. Yenza ukuhlolwa okuphelele nokuhlolwa kokusebenza kwemishini yokulethwa kukaphethiloli kanye nezishisi. Hlola ukusebenza kwamavalvu nezinsimbi zepayipi lokulethwa kukaphethiloli futhi uhlole ukwethembeka kwedivayisi yokunqamula uphethiloli.
b. Yenza ukuhlolwa okuphelele nokugcinwa kokunemba nokwethembeka kwazo zonke izisetshenziswa nezisetshenziswa zohlelo lokulawula okuzenzakalelayo. Yenza izivivinyo zesenzo nokuhlolwa kwedivayisi ngayinye exhumene.
C. Yenza ukuhlolwa kokusebenza, ukulungisa noma ukushintshwa kwezikali zokucindezela, amavalvu okuphepha, izikali zamazinga amanzi, ama-blowdown valves, ama-steam valves, njll.
d. Ukuhlola, ukulungisa nokudweba ukubukeka kwemishini.
