Panyaya yemusoro wemvura unogara uripo, kana gwara rekuvhura rasvika pakuvhurwa kweasina-mutoro, asi turbine haisati yasvika pakumhanya kwakayerwa, kana kana yakabuda imwe chete, iyo yekutungamira vane kuvhura yakakura kupfuura yekutanga, inoonekwa. kuti kubuda kwechikwata kwadzikira.Zvikonzero zvikuru zvekudonha kwezvakabuda ndezvi: 1. Kuyerera kwekurasikirwa kweturbine yemvura;2. Kurasikirwa kwekuchengetedza mvura kweturbine yemvura;3. Mechanical kurasikirwa kweturbine yemvura.
Processing
1. Kana chikwata chiri kushanda kana kuvhara, iva nechokwadi chokuti kudzika kwechubhu kunyura hakusi pasi pe300mm (kunze kweiyo 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.

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 pane nzira nhatu dzekuzora: mvura yekuzora, kuonda kwemafuta uye kuomeswa kwemafuta.Zvikonzero zvekukwira kwakanyanya kwekupisa kweshaft ndeiyi: kutanga, kutadza kutakura mhando yekuisa kana kutakura kupfeka;chechipiri, kukundikana kwegadziriro yemafuta ekuzora;chechitatu, kusapindirana kwemafuta ekuzora label kana kuti 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 yekutsvedza haibvumidzwe kunamira, mafuta anopihwa kune iyo thrust plate uye mwero wemafuta wetangi remafuta.
3. Gadzirisa mabhengi nemafuta akaoma.Chenjerera kuti zvinotsanangurwa zveoiri yakaoma zvinoenderana here nemafuta ekubereka, uye kana mhando yemafuta yakanaka, wedzera mafuta nguva nenguva kuti uve nechokwadi chekuti kutakura kubvumidzwa kuri 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 yebere rakazorwa kune hukama nekumanikidza kweyuniti yegwenzi rinotakura, kumhanya kwemutsara wekutenderera, nzira yekuzora, viscosity yemafuta, kugadziridzwa kwezvikamu, kugadzwa kwechokwadi uye Baidu ye. unit 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 kwakashata kana kugadziriswa kwegap hakuna kunaka, kunyanya gaka rakanyanya kukura;chechina, pane kukandirana 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 anotsemuka, izvo zvinoita kuti kuvhurwa 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, zvichikonzera kuzunguzika kweyuniti uye kutinhira kwekuyerera kwemvura.
(3) Kudengenyeka kwemagetsi, kudengenyeka kwechikwata chinokonzerwa nekurasikirwa kwechiyero kana kuchinja kamwe kamwe kwehuwandu hwemagetsi.
Zvikonzero: Imwe ndiyo kusaenzana kwakakomba kwematatu-chikamu ikozvino chejenareta, izvo zvinokonzera kusaenzana kwetatu-phase electromagnetic simba;imwe yacho ndeyekuchinja kwepakarepo kwezvino kunokonzerwa netsaona 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 nekusaenzana kunokonzerwa nekuremera kwemumhanyi, kusabatana kwakashata kwechikwata, uye eccentricity, iyo amplitude inowedzera nekuwedzera kwekukurumidza.;Chechitatu ndiyo kudengenyeka kunokonzerwa nepamusoro pemagetsi, amplitude inowedzera nekuwedzera kwekunakidza ikozvino, uye kudengenyeka kunogona kupera kana kuputika kuchibviswa;yechina ndeyekudedera kunokonzerwa necavitation, iyo amplitude inoenderana nenharaunda yemutoro, dzimwe nguva inokanganiswa, dzimwe nguva yakaoma, Panguva imwecheteyo, ruzha rwekugogodza runogadzirwa mudhizaini chubhu, uye panogona kunge paine chiitiko chekuzunguza pane vacuum. gauge.
Kupisa kwegwenzi rinotakura reyuniti rinowedzerwa kana rakanyanyisa

1. Zvikonzero zvekuchengetedza uye kuiswa: kuvuza kwebheshi remafuta, nzvimbo isina kururama yekuisa pombi yepombi, isingaenderane tile gap, kuzununguka kusina kujairika kwechikwata chinokonzerwa nemhando yekuisa, 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 kutonhora kwe tile kuchikwira, tanga kutarisa mafuta ekuzora, kuwedzera mafuta munguva kana kubata kuti uchinje mafuta;gadzirisa kutonhora kwemvura inotonhorera kana kushandura nzira yekupa mvura;edza kana kudzungudza kweyuniti kwakapfuura mwero uye kumisa kutenheka 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.

Kana gavhuna kuvhura kwakanyatso kuvharwa, mumhanyi haagone kumira kusvikira gwara rekuvhura rinenge risisakwanise kudzorwa.Situation iyi inonzi speed control failure.Zvikonzero: Chekutanga, chinongedzo vane 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 automatic speed governor.Kana iyo hydraulic turbine unit iri kushanda zvisina kujairika, kunyanya kana iyo unit iri munjodzi yekushanda kwakachengeteka, inofanirwa kuedza pakarepo 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. Nguva dzose chenesa 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.
