Kudonha kwemagetsi emagetsi emvura
(1) Chikonzero
Kana mvura iri mumusoro wemvura usingachinji, kana muromo wevane rekutungamira wasvika pakuvhurwa kusina mutoro, asi turbine isingasvike pakumhanya kwakatarwa, kana kana muromo wevane rekutungamira wakakura kupfuura wekutanga pakabuda chinhu chimwe chete, zvinofungidzirwa kuti kubuda kweyuniti kunoderera. Zvikonzero zvikuru zvekudzikira kwekubuda kwemvura ndeizvi: 1. Kurasikirwa nekuyerera kwe hydraulic turbine; 2. Kurasikirwa ne hydraulic turbine; 3. Kurasikirwa ne hydraulic turbine ne mechanical.

1. Kana turubhu iri kushanda kana kuvharwa, hudzamu hwechubhu yedhiragi hunofanira kunge husingasviki 300mm (kunze kweturbine ye impulse). 2. Tarisa kuyerera kwemvura kana kubuda kwayo kuti mvura irambe yakaenzana uye isina kuvharwa. 3. Chengeta runner ichimhanya mumamiriro ezvinhu akajairwa uye vhara kuti iongororwe uye irapwe kana paine ruzha. 4. Kana turbine ye axial flow fixed blade, kana kubuda kweturubhu kukadonha kamwe kamwe uye vibration ikawedzera, inofanira kuvharwa pakarepo kuti iongororwe.
2, Tembiricha yepedhi yekutakura zvinhu inokwira zvakanyanya
(1) Chikonzero
Kune mhando mbiri dzema "turbine bearing": "guide bearing" uye "thrust bearing". Mamiriro ekuona kuti bearing inoshanda zvakanaka ndeekuisa zvakanaka, "lubrication" yakanaka uye "cooking water supply" yakajairika. Nzira dzekuzora dzinowanzo sanganisira "water lubrication", "thin oil lubrication" uye "dry lubrication". Zvikonzero zvekukwira kwakanyanya kwekushisa kwe "shaft" ndeizvi: chekutanga, mhando ye "bearing" haina kunaka kana kuti "bearing" yakasakara; Chechipiri, "lubrication oil system" yakakundikana; Chechitatu, "lubrication oil label" haina kuenderana kana kuti "oil quality" haina kunaka; Chechina, "cooling water system" yakakundikana; Cheshanu, "unit" inodedera nekuda kwechimwe chikonzero; Chetanhatu, huwandu hweoiri hwe "bearing" hwakaderera zvakanyanya nekuda kwekubuda kweoiri.

1. Pamabheyari akanyoroveswa nemvura, mvura inonyorovesa inofanira kusefetwa zvakasimba kuti ive nechokwadi chekuti mvura yakanaka. Mvura haifanirwe kunge iine sediment yakawanda nezvinhu zvemafuta kuderedza kupera kwemabheyari uye kukwegura kwerabha.
2. Mabheya matete ane mafuta anowanzo tenderera ega, ane oil slinger ne thrust disc. Anotenderedzwa neyuniti uye anopihwa oiri ne self circulation. Nyatsoteerera mamiriro ekushanda kwe oil slinger. Oil slinger haifanirwe kunamirwa. Mafuta anoenda ku thrust disc uye huwandu hweoiri mu mail oil tank zvinofanira kunge zvakaenzana.
3. Nyora mafuta akaoma pabearing. Tarisa kana zvataurwa pamusoro pemafuta akaoma zvinoenderana nemafuta ebearing uye kana mhando yemafuta yakanaka. Wedzera mafuta nguva nenguva kuti uve nechokwadi chekuti nzvimbo yebearing iri 1/3 ~ 2/5.
4. Chivharo chepombi yemvura inopinza nekutonhodza chinofanira kunge chakagadzirwa kudzivirira mvura ine simba guruva kupinda mubearing nekukuvadza mafuta akajairika ebearing.
5. Kubviswa kwemafuta ekuisa mafuta kunoenderana nekumanikidzwa kweyuniti, kumhanya kwekutenderera kwakanangana, modhi yekuzora mafuta, viscosity yemafuta, kugadzirisa zvikamu, kunyatso shandiswa uye kudedera kweyuniti.
3, Kudedera kwechikamu
(1) Kudedera kwemuchina, kudedera kunokonzerwa nezvikonzero zvemuchina.
chikonzero; Chekutanga, turbine ye hydraulic yakarerekera; Chechipiri, nzvimbo iri pakati pe turbine yemvura nejenareta haina kunaka uye kubatana hakuna kunaka; Chechitatu, bearing ine zvikanganiso kana kugadziriswa kusina kunaka kwekubviswa kwemvura, kunyanya nzvimbo yacho yakakura kwazvo; Chechina, pane kukweshana uye kurovana pakati pezvikamu zvinotenderera nezvikamu zvisingachinji.
(2) Kudengenyeka kweHydraulic, kudengenyeka kweyuniti kunokonzerwa nekusagadzikana kwemvura inoyerera ichipinda mumuchina unoyerera.
Zvikonzero: chekutanga, guide vane yakakuvara uye bhaudhi ratyoka, zvichikonzera kuvhurika kwakasiyana kweguide vane uye kuyerera kwemvura kusina kuenzana kutenderedza runner; Chechipiri, kune akawanda ma volute mu volute kana kuti runner inovharwa nema akawanda ma dry, zvekuti kuyerera kwemvura kutenderedza runner hakuna kuenzana; Chechitatu, kuyerera kwemvura mu draft tube hakuna kugadzikana, zvichikonzera kuchinja nguva nenguva mukumanikidzwa kwemvura kwe draft tube, kana kuti mhepo inopinda mu spiral case ye hydraulic turbine, zvichikonzera kudedera kweyuniti uye ruzha rwekuyerera kwemvura.
(3) Kudengenyeka kwemagetsi kunoreva kudengenyeka kweyuniti kunokonzerwa nekurasikirwa nekuenzana kana kuchinja kamwe kamwe kwehuwandu hwemagetsi.
Zvikonzero: chekutanga, simba remagetsi remagetsi remaphase matatu harina kuenzana zvakanyanya. Nekuda kwekusaenzana kwemagetsi, simba remagetsi remaphase matatu harina kuenzana; Chechipiri, kuchinja kwemagetsi nekukurumidza kunokonzerwa netsaona yemagetsi kunoita kuti kumhanya kwejenareta neturbine kusawirirane nekukurumidza; Chechitatu, musiyano usina kuenzana pakati pe stator ne rotor unokonzera kusagadzikana kwesimba remagineti rinotenderera.
(4) Kudengenyeka kwemukati memugero, kudedera kwechikamu kunokonzerwa nekudengenyeka kwemukati memugero.
Zvikonzero: chekutanga, amplitude yevibration inokonzerwa nekusawirirana kwe hydraulic inowedzera nekuwedzera kwekuyerera; Chechipiri, vibration inokonzerwa nekusawirirana kwemumhanyi, kubatana kusina kunaka kweyuniti uye eccentricity, uye amplitude inowedzera nekuwedzera kwekumhanya kunotenderera; Chechitatu vibration inokonzerwa nejenareta yemagetsi. Amplitude inowedzera nekuwedzera kwe excitation current. Kana excitation yabviswa, vibration inogona kunyangarika; Chechina vibration inokonzerwa ne cavitation erosion. Amplitude yayo ine chekuita nenzvimbo yemutoro, dzimwe nguva inokanganiswa uye dzimwe nguva ine simba. Panguva imwe chete, kune ruzha rwekugogodza mu draft tube, uye panogona kuva ne swing pa vacuum meter.
4, Tembiricha yebearing pad yeyuniti inokwira uye yakakwira zvakanyanya
(1) Chikonzero
1. Zvikonzero zvekugadzirisa nekuisa: kubuda kwebheseni remafuta, nzvimbo isiriyo yekuisa pitot tube, mukaha usina kukodzera wemataira, kudedera kweyuniti kusingawanzoitika kunokonzerwa nehunhu hwekuisa, nezvimwewo;
2. Zvikonzero zvekushanda: kushanda munzvimbo inodedera, kutadza kuona kunaka kwemafuta ebhearing uye huwandu hwemafuta, kutadza kuwedzera mafuta nenguva, kutadza kuona kukanganiswa kwemvura inotonhorera uye huwandu hwemvura husina kukwana, zvichikonzera kushanda kwenguva refu kwemuchina usingamhanye zvakanyanya, nezvimwewo.
(2) Mubato
1. Kana tembiricha yebearing yakwira, tanga watarisa mafuta ekuzora, wedzera mafuta ekuwedzera nenguva kana kuti bata kuti utsive mafuta; Gadzirisa kumanikidzwa kwemvura inotonhorera kana chinja nzira yekupa mvura; Edza kana kuzununguka kweyuniti kuchidarika mwero. Kana kuzununguka kusingakwanise kubviswa, kunofanira kudzimwa;
2. Kana paine nzira yekudzivirira tembiricha, tarisa kana kudzima kwacho kwakajairika uye tarisa kana gwenzi rinopa simba rakatsva. Kana gwenzi ratsva, ritsive negwenzi idzva kana kurikuya zvakare.
5, Kukundikana kwekutonga kumhanya
Kana kuvhurwa kwegavhuna kwavharwa zvizere, mutyairi haagone kumira kusvika kuvhurwa kwevane yekutungamira kwatadza kudzorwa zvinobudirira. Izvi zvinonzi kukundikana kwekutonga kwekukurumidza. Zvikonzero: chekutanga, kubatana kwevane yekutungamira kwakakombama, izvo zvisingakwanise kudzora kuvhurwa kwevane yekutungamira zvinobudirira, zvekuti vane yekutungamira haigone kuvharwa, uye unit haigone kumira. Zvinofanira kucherechedzwa kuti mamwe mayuniti madiki haana zvishandiso zvemabhureki, uye unit haigone kumira kwechinguva pasi pekuita kwekusagadzikana. Panguva ino, usafunga zvisirizvo kuti haina kuvharwa. Kana ukaramba uchivhara vane yekutungamira, tsvimbo yekubatanidza ichakombama. Chechipiri, kukundikana kwekutonga kwekukurumidza kunokonzerwa nekukundikana kwegavhuna otomatiki. Kana unit ye turbine yemvura ikashanda zvisina kujairika, kunyanya kana unit ikatadza kushanda zvakachengeteka, edza kumisa muchina nekukurumidza kuti urapwe. Kumhanya zvishoma chete kunongowedzera kukanganisa. Kana gavhuna ikakundikana uye nzira yekuvhura vane yekutungamira ikasagona kumira, vharuvhu huru yeturbine inofanira kushandiswa kudimbura kuyerera kwemvura ichipinda muturbine.
Dzimwe nzira dzekurapa: 1. Gara uchichenesa nzvimbo dzakasiyana-siyana dzemuchina wekutungamira mvura, ramba wakachena, uye gara uchidira mafuta panzvimbo inofambiswa; 2. Raki yemarara inofanira kuiswa panzvimbo inopinzwa mvura uye kucheneswa nguva nenguva; 3. Kuti turbine ye hydraulic ishande nechero mudziyo wemotokari, nyatso tsiva ma brake pads nenguva uye wedzera mafuta e brake.
