Kubuda kwe hydro-generator kunodonha
Chikonzero
Kana paine musoro wemvura unogara uchienderera mberi, kana kuvhurwa kwevane yekutungamira kwasvika pakuvhurwa kusina mutoro, asi turbine isina kusvika kumhanya kwakayerwa, kana kana kubuda kwakafanana, kuvhurwa kwevane yekutungamira kwakakura kupfuura kwekutanga, zvinofungidzirwa kuti kubuda kweyuniti kwaderera. Zvikonzero zvikuru zvekudzikira kwekubuda ndeizvi: 1. Kurasikirwa nekuyerera kweturbine yemvura; 2. Kurasikirwa nekuchengetwa kweturbine yemvura; 3. Kurasikirwa kweturbine yemvura nemechanical.

1. Kana mudziyo uchimhanya kana kudzimwa, iva nechokwadi chekuti kudzika kwemvura inonyudzwa muchubhu yemhepo hakusi pasi pe300mm (kunze kweinjini yemhepo). 2. Tarisa kuyerera kwemvura kana kubuda kwayo kuti mvura irambe yakaenzana uye isina kuvharwa. 3. Chengeta runner ichimhanya zvakanaka, uye misa muchina kuti uongororwe kana paine ruzha. 4. Kune maturbine emagetsi anoyerera neaxial-flow, kana kubuda kwemudziyo kukangoerekana kwadzikira uye kudedera kukawedzera, kunofanira kudzimwa nekukurumidza kuti kuongororwe.
Kupisa kwegwenzi rinobereka reyuniti kunokwira zvakanyanya
Chikonzero
Kune mhando mbiri dzema "turbine bearing": "guide bearing" uye "thrust bearing". Mamiriro ekuona kuti bearing inoshanda zvakanaka ndeekuisa zvakanaka, "lubrication" yakanaka uye "cold water" inotonhorera. Kazhinji kune nzira nhatu dzeku "lubrication": "water lubrication", "thin oil lubrication" uye "dry lubrication". Zvikonzero zvekukwira kwakanyanya kwekushisa kwe "shaft" ndeizvi: chekutanga, "unless installation bearing" kana "bearing" yakasakara; chechipiri, "kukundikana" kwe "lubricating oil system"; chechitatu, "lubricating oil label" isingaenderane kana "unless oil"; chechina, "unless" ye "cooling water system"; chechishanu, nekuda kwechimwe chikonzero. Inoita kuti "unit" idengenyeke; chechitanhatu, "bearing oil" inodonha uye "oil level" yakaderera.

1. Mabheringi akanyoroveswa nemvura. Mvura inonyoroveswa inofanira kusefetwa zvakasimba kuti ive nechokwadi chekuti mvura yakanaka. Mvura haifanirwe kunge iine jecha nemafuta akawanda kuderedza kupera kwebheringi uye kukwegura kwerabha.
2. Mabheya akatetepa ane mafuta anowanzo tenderera ega, achitora oil slinger ne thrust plate, uye oiri inozvitenderera inopihwa nekutenderera kweyuniti. Nyatsoteerera mamiriro ekushanda kwe slinger ring. Ring ye slinger haibvumirwe kunamirwa, huwandu hwemafuta anoiswa mu thrust plate uye huwandu hwemafuta mutangi remafuta.
3. Nyora mafuta akaoma pamabheringi. Tarisa kana zvinodiwa nemafuta akaoma zvichienderana nemafuta ebheyingi, uye kana mhando yemafuta yakanaka, wedzera mafuta nguva nenguva kuti uve nechokwadi chekuti nzvimbo yebheyingi iri 1/3 ~ 2/5.
4. Chishandiso chekuvhara pombi yemvura inopinza mvura neinotonhodza hachina kuvharwa kudzivirira mvura ine simba guruva kupinda mubearing nekuparadza mafuta akajairika ebearing.
5. Kubviswa kwebearing yakanyoroveswa kunoenderana nekumanikidzwa kweyuniti yebush rebearing, kumhanya kwekutenderera kwakanangana, nzira yekunyorovesa, viscosity yemafuta, kugadziriswa kwezvikamu, kunyatsoiswa kwekuisa uye Baidu yekuzununguka kweyuniti.
Kudedera kwechikamu
(1) Kudedera kwemuchina, kudedera kunokonzerwa nezvikonzero zvemuchina.
Zvikonzero: Chekutanga, turbine ye hydraulic inorema zvakanyanya; chechipiri, axis ye turbine nejenareta haina kunaka, uye kubatana hakuna kunaka; chechitatu, bearing haina kunaka kana kugadziriswa kwegap hakuna kunaka, kunyanya gap yakakura zvakanyanya; chechina, pane kukweshana pakati pezvikamu zvinotenderera nezvikamu zvisingachinji.
(2) Kudengenyeka kwe hydraulic, kudengenyeka kweyuniti kunokonzerwa nekurasikirwa kwechiyero chemvura inoyerera ichipinda mumuchina.
Zvikonzero: Chimwe ndechekuti guide vane inotyora bhaudhi yotyoka, izvo zvinoita kuti kuvhurika kweguide vane kushanduke, zvekuti kuyerera kwemvura yakatenderedza runner hakuna kuenzana; chimwe ndechekuti pane marara muvolute kana kuti runner yakavharika, zvichiita kuti iyerere murunner. Kuyerera kwemvura kwakatenderedza hakuna kuenzana; chechitatu, kuyerera kwemvura mudraft tube hakuna kugadzikana, izvo zvinoita kuti kumanikidzwa kwemvura kwedraft tube kuchinje nguva nenguva, kana kuti mhepo inopinda muvolute yeturbine, zvichikonzera kudedera kweyuniti uye ruzha rwekuyerera kwemvura.
(3) Kudengenyeka kwemagetsi, kudengenyeka kweyuniti kunokonzerwa nekurasikirwa nekuenzana kana kuchinja kamwe kamwe kwehuwandu hwemagetsi.
Zvikonzero: Chimwe chikonzero ndechekusawirirana kwakakomba kwesimba remagetsi remaphase matatu, izvo zvinokonzera kusawirirana kwesimba remagetsi remaphase matatu; chimwe chikonzero ndechekuchinja kwesimba remagetsi panguva imwe chete kunokonzerwa netsaona yemagetsi, izvo zvinoita kuti jenareta neturbine zvisakwanise kuwiriranisa kumhanya kwazvo ipapo ipapo. ; Chechitatu, musiyano uripo pakati pe stator ne rotor hauna kufanana, zvichikonzera kusagadzikana kwesimba remagineti rinotenderera.
(4) Kudedera kwemudumbu, kudedera kwechikamu kunokonzerwa nedenda.
Zvikonzero: Chekutanga, kudedera kunokonzerwa nekusawirirana kwe hydraulic, amplitude yayo inowedzera nekuwedzera kwekuyerera; chechipiri kudedera kunokonzerwa nekusawirirana kunokonzerwa nekurema kwemumhanyi, kubatana kusina kunaka kweyuniti, uye eccentricity, amplitude yayo inowedzera nekuwedzera kwekumhanya. ; Chechitatu kudedera kunokonzerwa nepamusoro pemagetsi, amplitude inowedzera nekuwedzera kwe excitation current, uye kudedera kunogona kunyangarika kana excitation yabviswa; chechina kudedera kunokonzerwa ne cavitation, iyo amplitude yayo ine chekuita nenzvimbo yemutoro, dzimwe nguva inokanganiswa, dzimwe nguva yakanyanya. Panguva imwe chete, ruzha rwekugogodza runogadzirwa mu draft tube, uye panogona kunge paine swing phenomenon pa vacuum gauge.
Kupisa kwegwenzi rinobata bheyaringi reyuniti kwakawedzera kana kuti kwakakwira zvakanyanya
Chikonzero
1. Zvikonzero zvekugadzirisa nekuisa: kubuda kwebheseni remafuta, nzvimbo isiriyo yekuisa pipe, mukaha wemataira usingaenderane nezvinodiwa, kudedera kusingawanzoitika kwechinhu kunokonzerwa nehunhu hwekuisa, nezvimwewo;
2. Zvikonzero zvekushanda: kushanda munzvimbo inodedera, kutarisa kunaka kwemafuta ebhearing uye huwandu hwemafuta, kutadza kuzadza mafuta nenguva, kukanganiswa kwemvura inotonhodza, kutarisa kushomeka kwemvura, uye kushanda kwenguva refu kweyuniti nekukurumidza.
Kugadzirisa
1. Kana tembiricha yemataira yakwira, tanga watarisa mafuta ekuzora, wedzera mafuta nenguva kana kuti batanidza kuti uchinje mafuta; gadzirisa kumanikidzwa kwemvura inotonhorera kana chinja nzira yekupa mvura; edza kana kudedera kweyuniti kuchidarika mwero uye misa kudedera kana kudedera kusingagone kubviswa;
2. Kana tembiricha ichidzivirira nzira yekubuda nayo, inofanira kutariswa uye kuvharwa zvakanaka, uye kutarisa kana gwenzi remabheyaringi ratsva. Kana gwenzi remabheyaringi ratsva, rinofanira kutsiviwa netaira itsva kana kukwenywa patsva.
Chishanu, kutadza kudzora kumhanya
Kana kuvhurwa kwegavhuna kwavharwa zvizere, mumhanyi haagone kumira kusvika kuvhurwa kwevane yekutungamira kwatadza kudzorwa zvinobudirira. Mamiriro aya anonzi kukundikana kwekudzora kumhanya. Zvikonzero: Chekutanga, kubatana kwevane yekutungamira kwakakombama, uye kuvhurwa kwevane yekutungamira hakugone kudzorwa zvinobudirira, zvichiita kuti vane yekutungamira ivharwe uye unit haigone kumira. Zvinofanira kucherechedzwa kuti mamwe mayuniti madiki haana mudziyo webhureki, uye unit haigone kumira kwenguva yakati pasi pekuita kwekusashanda zvakanaka. Panguva ino, usazvifungidzira kuti yavharwa. Kana ukaramba uchivhara vane yekutungamira, tsvimbo yekubatanidza ichakombama. Chechipiri ndechekuti kudzora kumhanya kunokundikana nekuda kwekutadza kwegavene yekukurumidza otomatiki. Kana unit ye hydraulic turbine iri kushanda zvisina kujairika, kunyanya kana unit iri mudambudziko rekushanda kwakachengeteka, inofanira kuedza kudzima nekukurumidza uye kugadzirisa nayo. Kushanda kusingadzoreki kunongowedzera kukundikana. Kana gavene ikakundikana uye nzira yekuvhura vane yekutungamira isingakwanise kumira, vharuvhu huru yeturbine inofanira kushandiswa kudimbura kuyerera kwemvura ichipinda muturbine.
Dzimwe nzira dzekurapa: 1. Gara uchichenesa marara ari muchina wekutungamira mvura, ramba wakachena, uye wedzera mafuta munzvimbo dzinofamba nguva dzose; 2. Nzvimbo yekupinda mvura inofanira kunge ine machira emarara uye ichibviswa nguva nenguva; 3. Maturbine emota dzinofanira kutsiviwa nenguva. Mapadhi ebhureki, wedzera mvura yebhureki.
