Kubuda kwehydro-jenareta kunodonha
Chikonzero
Panyaya yemusoro wemvura unogara uripo, kana gwara rekuvhura rasvika pakuvhurwa kweasina-mutoro, asi turbine haisati yasvika payero yakayerwa, kana kana iyo yakabuda yakafanana, iyo gwara vane kuvhura yakakura kupfuura yekutanga, inofungidzirwa kuti kubuda kweiyo unit kwadzikira. Zvikonzero zvikuru zvekudonha kwezvinobuda ndezvi: 1. Kuyerera kwekurasikirwa kweturbine yemvura; 2. Kurasikirwa kwekuchengetedza mvura kweturbine yemvura; 3. Mechanical kurasikirwa kweturbine yemvura.
Processing
1. Kana iyo unit ichimhanya kana kudzima, iva nechokwadi chekuti kudzika kwechubhu kudzika hakusi pasi pe300mm (kunze kweiyo inokanganisa turbine). 2. Chenjerera kumvura inopinda kana kubuda kuti uchengetedze kuyerera kwemvura mukuenzanisa uye kusina kuvharwa. 3. Chengeta mumhanyi achimhanya ari muchimiro chenguva dzose, uye misa muchina kuti uongororwe kana pane ruzha. 4. Kune axial-flow fixed-blade turbines, kana kubuda kwechikwata kunodonha kamwe kamwe uye kudengenyeka kunowedzera, inofanira kuvharwa pakarepo kuti iongororwe.
Kupisa kwegwenzi rinotakura rechikwata rinokwira zvakanyanya

Kune marudzi maviri eturbine bearings: giredhi kutakura uye thrust bear. Mamiriro ezvinhu ekuona kushanda kwakajairwa kwebearing kuisirwa kwakaringana, kukwirisa kwakanaka uye kupihwa kwakajairika kwemvura inotonhorera. Kazhinji kune nzira nhatu dzekuzora: kukwirisa mvura, kuonda kwemafuta uye kuomeswa kwemafuta. Zvikonzero zvekukwira kwakanyanya kwekupisa kweshaft ndezvi: kutanga, kutadza kutakura kuisirwa kunaka kana kutakura kupfeka; chechipiri, kukundikana kwegadziriro yemafuta ekuzora; chechitatu, kusapindirana kwemafuta ekuzora label kana mafuta asina kunaka; chechina, kukundikana kwegadziriro yemvura inotonhorera; cheshanu, nekuda kwechimwe chikonzero Ita kuti chikwata chizunguze; Yechitanhatu, mafuta ekubereka anodonha uye mwero wemafuta wakadzikira.
Processing
1. Mvura-rubricated bearings. Mvura yekuzora inofanira kucheneswa kuti ive nechokwadi chemhando yemvura. Mvura haifaniri kuva nehuwandu hwejecha nemafuta kuderedza kupera kwekutakura uye kukwegura kwerabha.
2. Oiri matete anozora mabearings anowanzo atora self-circulation, kutora oiri slinger uye thrust plate, uye oiri inotenderera yega inopihwa nekutenderera kwechikamu. Nyatsoteerera kumamiriro ekushanda kwemhete ye slinger. Mhete inotsvedza haibvumidzwe kunamatira, iyo mafuta anopihwa kune iyo thrust plate uye mwero wemafuta wetangi remafuta.
3. Gadzirisa mabhengi nemafuta akaoma. Ngwarira kuti zvinotsanangurwa zveoiri yakaoma zvinoenderana nemafuta ekubereka, uye kana mhando yemafuta yakanaka, wedzera mafuta nguva nenguva kuti uve nechokwadi chekuti kutakura chibvumirano chiri 1/3 ~ 2/5.
4. Chisimbiso chekuisa chisimbiso chekutakura uye kutonhora kwepombi yemvura yakagadzikana kudzivirira mvura yekumanikidza uye guruva kubva pakupinda mubereko uye kuparadza yakajairika lubrication yekutakura.
5. Kuiswa kwemvumo yebeche yakaomeswa inoenderana neiyo unit kudzvanywa kwegwenzi rinotakura, mutsara wekutenderera kwekutenderera, nzira yekuzora, viscosity yemafuta, kugadziridzwa kwezvikamu, kugadzika kwechokwadi uye Baidu yeyuniti vibration.
Unit vibration
(1) Mechanical vibration, vibration inokonzerwa nezvikonzero zvemuchina.
Zvikonzero: Kutanga, iyo hydraulic turbine inorema zvakanyanya; chechipiri, axis ye turbine uye jenareta haina kunaka, uye kubatana hakuna kunaka; chechitatu, kubereka hakuna kukanganisa kana kugadzirisa kwegap hakuna kunaka, kunyanya gaka rakanyanya kukura; chechina, pane kupesana pakati pezvikamu zvinotenderera nezvikamu zvakamira. kudhumhana
(2) Hydraulic vibration, kudengenyeka kwechikwata chinokonzerwa nekurasikirwa kwekuenzanisa kwemvura inoyerera ichipinda mumhanyi.
Zvikonzero: Imwe ndeyokuti mutungamiri vane anoputsa bhaudhi uye anoputsika, izvo zvinoita kuti kuvhura kwevheji yemutungamiri kusiyanisa, kuitira kuti kuyerera kwemvura kunopoteredza mumhanyi kusaenzana; imwe yacho ndeyokuti pane marara muvolute kana kuti mumhanyi akazara, zvichiita kuti iyerere mumumhanyi. Mvura inoyerera kumativi ose haina kuenzana; chechitatu, kuyerera kwemvura muchubhu yekudhirowa haina kugadzikana, izvo zvinoita kuti dzvinyiriro yemvura yechubhu inodhirowe ichinje nguva nenguva, kana mhepo inopinda muvolute yeturbine, ichikonzera kuzunguzika kweyuniti uye kutinhira kwekuyerera kwemvura.
(3) Kudengenyeka kwemagetsi, kudengenyeka kwechikwata chinokonzerwa nekurasikirwa kwechiyero kana kuchinja kamwe kamwe kwehuwandu hwemagetsi.
Zvikonzero: Chimwe ndicho kusaenzana kwakakomba kwematatu-chikamu ikozvino chejenareta, izvo zvinokonzera kusaenzana kwetatu-phase electromagnetic force; imwe yacho ndeyekuchinja kwepakarepo kwezvino kunokonzerwa nenjodzi yemagetsi, izvo zvinoita kuti jenareta uye turbine zvisakwanise kuwiriranisa kumhanya kwavo pakarepo. ; Chechitatu, musiyano pakati pe stator uye rotor haisi yunifomu, zvichiita kuti kusagadzikana kweiyo inotenderera magnetic field.
(4) Cavitation vibration, kudengenyeka kwechikwata chinokonzerwa ne cavitation.
Zvikonzero: Kutanga, kudengenyeka kunokonzerwa ne hydraulic imbalance, iyo amplitude inowedzera nekuwedzera kwekuyerera; yechipiri ndiyo kudengenyeka kunokonzerwa nekusagadzikana kunokonzerwa nekuremera kwemumhanyi, kusabatana kwakashata kwechikwata, uye eccentricity, iyo amplitude inowedzera nekuwedzera kwekukurumidza. ; Chechitatu kudengenyeka kunokonzerwa nepamusoro pemagetsi, iyo amplitude inowedzera nekuwedzera kwekunakidza ikozvino, uye kuzununguka kunogona kupera kana kuputika kunobviswa; yechina ndeyekudedera kunokonzerwa necavitation, iyo amplitude inoenderana nenharaunda yemutoro, dzimwe nguva inokanganiswa, dzimwe nguva yakaoma, Panguva imwecheteyo, ruzha rwekugogodza runogadzirwa mudhizaini yechubhu, uye panogona kunge paine swing phenomenon pane vacuum gauge.
Kupisa kwegwenzi rinotakura reyuniti rinowedzera kana rakanyanyisa
Chikonzero
1. Zvikonzero zvekuchengetedza uye kuisirwa: kuvuza kwebheshi remafuta, nzvimbo isiriyo yekuisa pombi yepombi, isingaenderane tile gap, kusagadzikana kudengenyeka kweiyo unit kunokonzerwa nekuiswa kwemhando, nezvimwewo;
2. Zvikonzero zvekushanda: kushanda munzvimbo yekudengenyeka, kutarisa kwemaitiro asina kujairika anotakura mafuta uye chiyero chemafuta, kukundikana kuzadza mafuta nenguva, kukanganiswa kwemvura inotonhorera, kutarisa kwekushayikwa kwemvura, uye kushanda kwenguva refu kwechikwata.
Processing
1. Kana tembiricha ye tile ichikwira, tanga watarisa mafuta ekuzora, wedzera mafuta munguva kana kubata kuti uchinje mafuta; gadzirisa kutonhora kwemvura inotonhora kana kushandura nzira yekupa mvura; edza kana vibration yeyuniti ichipfuura mwero uye kumisa vibration kana vibration isingakwanisi kubviswa;
2. Kana kutonhora kuchidzivirira kubuda, kunofanira kuongororwa uye kuvhara kazhinji, uye kutarisa kana gwenzi rinotakura rakatsva. Kamwe gwenzi rinotakura rinopiswa, rinofanira kuchinjwa netairi itsva kana kubviswa zvakare.
shanu, kukurumidza kudzora kutadza
Kana gavhuna kuvhura kwakanyatso kuvharwa, mumhanyi haagone kumira kusvikira gwara rekuvhura rinenge risisakwanise kudzorwa. Situation iyi inonzi speed control failure. Zvikonzero: Chekutanga, chinongedzo chine chinongedzo chakakotama, uye gwara rekuvhura rinenge risingagone kudzorwa zvakanaka, zvichiita kuti gwara revhare rivhare uye iyo unit haigone kumiswa. Izvo zvinofanirwa kucherechedzwa kuti mamwe madiki madiki haana bhureki mudziyo, uye iyo unit haigone kumira kwechinguva pasi pechiito che inertia. Panguva ino, usakanganise kuti yakavharwa. Kana iwe ukaramba uchivhara mavheti ekutungamira, tsvimbo yekubatanidza ichakotama. Chechipiri ndechekuti iyo yekumhanyisa control inotadza nekuda kwekutadza kweiyo otomatiki yekumhanyisa gavhuna. Kana iyo hydraulic turbine unit iri kushanda zvisina kujairika, kunyanya kana iyo unit iri munjodzi yekushanda kwakachengeteka, inofanirwa kuyedza nekukurumidza kuvhara uye kubata nayo. Kusada kushanda kunongowedzera kutadza. Kana gavhuna akatadza uye gwara rekuvhura rinokwanisa kumiswa, vharuvhu huru yeturbine inofanira kushandiswa kucheka kuyerera kwemvura muturbine.
Dzimwe nzira dzokurapa: 1. Gara uchichenesa tsvina mumvura inotungamira nzira, ichengetedze yakachena, uye wedzera mafuta pazvikamu zvinofamba nguva dzose; 2. Chiteshi chemvura chinopinda chinofanirwa kuve chakashongedzerwa marara uye kucheneswa kazhinji; 3. Maturbine emhando ipi neipi yekumisikidza mota anofanirwa kutsiviwa nenguva Mabhureki pads, wedzera brake fluid.
