Kutakura chinhu chakakosha pakutsigira mashandiro akajairika emota, kuwedzera pakudzora maitiro ekugadzira, dhizaini uye magadzirirwo ekutakura mota kwakakosha zvikuru, sengemota yakatwasuka uye mota yakatwasukaKana injini ikasasarudza mabheyaringi akasiyana, zvinodikanwa zvekumhanya zvakasiyana zvemota zvinofanirawo kusarudza mabheyaringi akasiyana.
1 magadzirirwo eMabheyaringi emota akatambanuka
Bhora rebhora nekoramu rinofanira kushandiswa zvakanyanya sezvinobvira kumativi ese ari maviri emota yakatwasukaParizvino, mota yemumba ine matanda maviri madiki nepakati inoshandisa mabheya ebhora anopfuura maviri, kunyangwe vamwe vagadziri vakagadzirisa nzvimbo yekushivirira yedhayamita yemukati yebheya munzira yekubvisa, kuitira kuderedza dambudziko rekuti bhora rinodzvanywa mushure mekunge beya rapiswa. Zvisinei, nekuda kwekuti expansion coefficient yebheya rebheya yakakura kupfuura yezvikamu zvesimbi zvakaumbwa zvine kamuri rebheya - chivharo chekupedzisira kana sleeve yebheya, uye tembiricha iri pajeya rebheya yakakwirawo, beya rebheya rinogona kutsvedza zvishoma mukamuri rebheya patembiricha yemumba, asi beya rinogona kusakwanisa kufamba mushure mekupiswa panguva yekushanda. Ichi ndicho chikonzero chikuru nei hupenyu hwebheya hupfupi uye huri nyore kupisa kana mabheya maviri ebhora ashandiswa. Mushure mekuyedzwa kwekukwira kwekushisa kwemota ine mabhora maviri, mota inomiswa kuyera kukwira kwekushisa, uye dzimwe nguva bearing yemota inotsva kechipiri, chikonzero ndechekuti kucheneswa kwebearing yebhora hakugone kutsungirira kuwedzera kwekupisa uye kutonhora kwerotor, uye jekete harigone kupinda mubearing room, kuitira kuti bhora rigone kutakura simba guru re axial rinokonzerwa ne.
Kana bhora rimwe chete rekuberekera uye koramu imwe chete yekuberekera zvikasarudzwa, matambudziko ari pamusoro apa anogona kudzivirirwa. Nefekitori yemota iri nani munhamba yefuremu yeH560 muMota ine simba guru ine matanda maviri, kubva pakushandiswa kwekutanga kwemabheyaringi maviri ebhora kusvika kubheyaringi rebhora, bearing rekoramu, mhedzisiro yekushanda kwekupedzisira yakanaka kwazvo. Pamusoro pekutsiva mabheyaringi zvichienderana nekugara uchigadzirisa, hapana chikanganiso panguva yekushanda kwakajairika. Uye tembiricha inoyerwa pabheyaringi i20℃ chete. Iyi ndiyo nyaya yekutanga yakabudirira yekushandura mabheyaringi maviri ebhora kuita bearing rimwe chete uye bearing rekoramu rimwe chete remamota ane 2-pole muChina, uye yave ichisimudzirwa zvishoma nezvishoma pamamota asingaputike.
Kuti dambudziko rekupisa neruzha rigadziriswe mushure mekunge kumhanya kwebhora kwatsiviwa nemabereri ekoramu, mabereri ekoramu echiedza anogona kushandiswa, uye akaiswa pamucheto wekunze wefeni, mamiriro ekutonhodza akanaka, uye ruzha rwebereri runogonawo kunyudzwa neruzha rwefeni. Kana simba remota ine 2-pole rakakura, mhando yebereri yakakura, uye light series yemabereri ekoramu akaoma kusangana nezvinodiwa zvekumhanya kwemuganhu, grisi yebereri inogonawo kuchinjwa kuita mafuta matete.
2 Kugadziriswa kwemabheyaringi emota akamira
Kana mota yakamira ichishandiswa kudhonza pombi yebhareri mu petrochemical system, nekuda kwesimba re axial rinokwira nekukurumidza repombi yebhareri ine nhanho dzakawanda pakutanga, pamwe chete nezvinodiwa zvekufambisa, uye kuti kubviswe kukuvara kunokonzerwa nekuwedzera kwekushisa kwe rotor kuenda ku bearing, mota yebhareri yebhareri ye vertical (dzose dziri 2 poles kana 4 poles), bearing yepamusoro yemota inofanira kusarudzwa mabearing maviri ebhora re centripetal thrust. Mabearing e column emabearing akaderera anofanira kusarudzwa se light series. Kuti kudzivirire kukuvara kwemabearing ebhora e thrust, twoomabheyaringi anofanira kunge aine simba re axial rakaiswa kare pajaketi re bearing. Saizi yesimba iri ndeyekuona kuti bearing haina kukuvara nesimba re axial reverse kubva kumagumo ekuwedzera kweshaft kusvika kumagumo asina mutoro panguva yekufambisa nekutanga.
