Ezinye iingxaki ziya kwenzeka ukuba i-generator yomphunga isetyenziswe ixesha elide. Ngoko ke, kufuneka sinikele ingqalelo kumsebenzi ohambelanayo wokulondoloza xa usebenzisa i-generator ye-steam kubomi bemihla ngemihla. Namhlanje, masithethe nawe malunga neendlela zokugcinwa kwemihla ngemihla kunye nemijikelo yokulondolozwa kweejenereyitha zomphunga.
1. Ukugcinwa rhoqo kwejenereyitha yomphunga
1.Igeyiji yomgangatho wamanzi
Hlanza imitha yomgangatho wamanzi ubuncinane kube kanye kwishifti nganye ukugcina ipleyiti yeglasi yomgangatho wamanzi icocekile, qinisekisa ukuba indawo ebonakalayo yemitha yomgangatho wamanzi icacile, kwaye nenqanaba lamanzi lichanekile kwaye lithembekile. Ukuba i-gasket yeglasi ivuza amanzi okanye i-steam, qinisa okanye ubeke indawo yokuzalisa ngexesha.
⒉Umgangatho wamanzi embizeni
Iqondwa yinkqubo yokulawula ukunikezelwa kwamanzi ngokuzenzekelayo, kwaye ulawulo lwamanzi luthatha isakhiwo se-electrode. Uvakalelo kunye nokuthembeka kokulawulwa komgangatho wamanzi kufuneka kuhlolwe rhoqo.
3. Umlawuli woxinzelelo
Uvakalelo kunye nokuthembeka komlawuli woxinzelelo kufuneka kuhlolwe rhoqo.
4. Igeyiji yoxinzelelo
Ukuba igeyiji yoxinzelelo isebenza ngokufanelekileyo kufuneka ihlolwe rhoqo. Ukuba i-gauge yoxinzelelo ifunyenwe ukuba yonakaliswe okanye ingasebenzi kakuhle, isithando somlilo kufuneka sivalwe ngokukhawuleza ukulungiswa okanye ukutshintshwa. Ukuqinisekisa ukuchaneka kwegeyiji yoxinzelelo, kufuneka ilinganiswe ubuncinane kanye kwiinyanga ezintandathu.
5. Ukukhutshwa kwamanzi amdaka
Ngokuqhelekileyo, amanzi okutya aqulethe iindidi zeeminerali. Emva kokuba amanzi okutya angena kwijenereyitha yomphunga kwaye afudunyezwe kwaye abe ngumphunga, ezi zinto ziya kudlula. Xa amanzi ebhoyila egxininiswe kwinqanaba elithile, ezi zinto ziya kuhlala ebhodweni kwaye zenze isikali. Okukhona umphunga usiba mkhulu, kokukhona uba ngumphunga. Okukhona umsebenzi uqhuba, kokukhona kukhula intlenga. Ukuze kuthintelwe izingozi ze-steam generator ezibangelwa isikali kunye ne-slag, umgangatho wokubonelela ngamanzi kufuneka uqinisekiswe kwaye i-alkalinity yamanzi kwibhoyili kufuneka iyancipha; ngokuqhelekileyo xa i-alkalinity yebhoyila yamanzi ingaphezulu kwe-20 mg elinganayo / ilitha, ugutyulo kufuneka lukhutshwe.
2. Umjikelo wokugcinwa kwejenereyitha yomphunga
1. Khupha ilindle yonke imihla
Ijenereyitha yomphunga kufuneka ikhutshwe yonke imihla, kwaye i-blowdown nganye kufuneka ithotywe ngaphantsi komgangatho wamanzi wejenereyitha yomphunga.
2. Emva kokuba isixhobo siqhube iiveki ezi-2-3, le miba ilandelayo kufuneka igcinwe:
a. Yenza uhlolo olubanzi kunye nomlinganiselo wesixhobo solawulo oluzenzekelayo kunye nezixhobo. Izixhobo zokufumanisa ezibalulekileyo kunye nezixhobo zokulawula ngokuzenzekelayo ezifana nenqanaba lamanzi kunye noxinzelelo kufuneka zisebenze ngokuqhelekileyo;
b. Qwalasela inyanda yombhobho we-convection kunye nesilondolozi samandla, kwaye ususe nakuphi na ukuqokelelwa kothuli ukuba kukho nayiphi na. Ukuba akukho kuqokelelana kothuli, ixesha lokuhlola linokwandiswa kube kanye ngenyanga. Ukuba akukabikho kuqokelelwa kothuli, uhlolo lunokwandiswa kube kanye rhoqo kwiinyanga ezi-2 ukuya kwezi-3. Ngexesha elifanayo, khangela ukuba kukho ukuvuza kwi-welding joint of the end pipe. Ukuba kukho ukuvuza, kufuneka kulungiswe ngexesha;
c. Jonga ukuba inqanaba le-oyile yegubu kunye nedrafti yedrafti yesitulo esinefeni siqhelekile, kwaye umbhobho wamanzi okupholisa kufuneka ube mpuluswa;
d. Ukuba kukho ukuvuza kumanqanaba omgangatho wamanzi, iivalve, iiflange zepayipi, njl., kufuneka zilungiswe.
3. Emva kweenyanga ezi-3 ukuya kwezi-6 zokusebenza kwejeneretha ye-steam, ibhoyili kufuneka ivalwe ukuze ihlolwe ngokubanzi kunye nokugcinwa. Ukongeza kulo msebenzi ungasentla, lo msebenzi ulandelayo wokugcinwa kwejenereyitha yomphunga uyafuneka:
a. Izilawuli zomgangatho wamanzi wohlobo lwe-Electrode kufuneka zicoce i-electrode yomgangatho wamanzi, kwaye iigeji zoxinzelelo eziye zasetyenziswa kwiinyanga ezi-6 kufuneka zihlaziywe;
b. Vula ikhava ephezulu ye-economizer kunye ne-condenser, susa uthuli oluqokelelwe ngaphandle kweetyhubhu, susa ii-elbows, kwaye ususe ukungcola kwangaphakathi;
c. Susa isikali kunye ne-sludge ngaphakathi kwidramu, ityhubhu yodonga olupholileyo ngamanzi kunye nebhokisi lentloko, hlamba ngamanzi acocekileyo, kwaye ususe i-soot kunye nomlotha wesithando somlilo eludongeni olupholileyo lwamanzi kunye nomlilo womlilo wedramu;
d. Khangela ngaphakathi nangaphandle kwejenereyitha yomphunga, njenge-welds yeendawo ezithwele uxinzelelo kunye nokuba kukho nayiphi na i-corrosion ngaphakathi nangaphandle kweepleyiti zensimbi. Ukuba iziphene zifunyenwe, kufuneka zilungiswe ngokukhawuleza. Ukuba i-defect ayinzima, inokushiywa ukuba ilungiswe ngexesha lokuvalwa kwesithando somlilo. Ukuba kukho nantoni na ekrokrisayo efunyenweyo kodwa ayichaphazeli ukhuseleko lwemveliso, irekhodi kufuneka lenziwe ukuze lisetyenziswe kwixesha elizayo;
e. Khangela ukuba i-rolling bearing yedrafti yedrafti ye-fan iyinto eqhelekileyo kunye neqondo lokunxiba kwe-impeller kunye negobolondo;
f. Ukuba kuyimfuneko, susa udonga lwesithando somlilo, igobolondo yangaphandle, i-insulation layer, njl. Ukuba kukho nawuphi na umonakalo omkhulu ofunyenweyo, kufuneka ulungiswe ngaphambi kokuqhubeka ukusetyenziswa. Ngexesha elifanayo, iziphumo zokuhlola kunye nesimo sokulungisa kufuneka zizaliswe kwincwadi yokubhaliswa kobugcisa be-steam generator.
4. Ukuba ijenereyitha yomphunga sele isebenze ngaphezu konyaka omnye, kufuneka kwenziwe lo msebenzi ulandelayo wokulondoloza ijenereyitha yomphunga:
a. Ukuqhuba uhlolo olubanzi kunye nokuvavanya ukusebenza kwezixhobo zenkqubo yokuhanjiswa kwamafutha kunye nezitshisi. Jonga ukusebenza kweevalvu kunye nezixhobo zombhobho wokuhanjiswa kwamafutha kwaye uvavanye ukuthembeka kwesixhobo sokucinywa kwamafutha.
b. Ukuqhuba uvavanyo olubanzi kunye nokugcinwa kokuchaneka kunye nokuthembeka kwazo zonke izixhobo zenkqubo yokulawula ngokuzenzekelayo kunye nezixhobo. Yenza iimvavanyo zesenzo kunye novavanyo lwesixhobo ngasinye esinxibelelanayo.
C. Yenza uvavanyo lokusebenza, ukulungiswa okanye ukutshintshwa kwee-gauges zoxinzelelo, iivalve zokhuseleko, i-water gauges level, ii-valve ze-blowdown, ii-valve ze-steam, njl.
d. Yenza uhlolo, ukugcinwa kunye nokupeyinta inkangeleko yesixhobo.
