Okwesithathu, ukwakheka kwedivayisi yokujika
Igiya elijikayo le-turbine yesitimu ikakhulukazi lakhiwe igiya lezikelemu, igiya lezikelemu (isilinganiso sokudlulisela i=27.5) kanye ne-clutch kagesi. Inhlanganisela ye-geared motor kanye ne-electromagnetic clutch isetshenziselwa ukufaka esikhundleni isilinda samafutha. I-torque esebenzayo iyafana, futhi isenzo sohlelo lwenduku yokuxhuma sidluliselwa nge-belt drive. Kuhle ngempela ukuthi ukuhlolwa kwefekthri noma indawo yokuphehla amandla iyasebenza. I-clutch ihlanganisa ama-sliding parts, ama-pawl, amagiya angaphakathi e-helical, amagiya angaphandle nama-buffer. Uhlangothi lwangaphakathi lwelungu elishelelayo lunikezwa amazinyo e-ratchet namagiya angaphakathi (amazinyo aqondile), kanti uhlangothi lwangaphandle luyigiya langaphandle eli-spiral. Ingxenye kagesi yedrayivu ye-steam turbine cranking car ithatha ukudluliswa komshini. Injini yayo yokushayela (37kw, 380v, 1475rpm) idlula ku-coupling yoketshezi, futhi umshini oxhumanisayo ophakathi nendawo ushayela imoto enyakazayo ye-steam turbine ukuze ijikelezise umshini weyunithi ngesivinini esikhulu esingu-54rpm.
Ngokuvamile kunezinhlobo ezimbili zejubane lokunyakazisa: isivinini esiphansi sokuklolodela ngo-2 ~ 4rpm kanye nesivinini esiphezulu esingu-40~70rpm: Kumayunithi amakhulu, ukuze kwakheke ifilimu likawoyela elithwele, gwema ukuthwala kanye nokugqoka kwejenali; futhi unciphise umehluko wokushisa kanye nokufinyezwa kwamasilinda aphezulu naphansi Isikhathi esiningi sokuqala ukugenceka ngesivinini esikhulu.
Okwesine, isimiso sokusebenza sedivayisi yokuguqula
Lapho igiya elijikayo lisebenza, injini ishayela indandatho yegiya kurota ye-turbine yesitimu ukuze ijikelezise isibungu, unqenqema lwesikelemu, kanye negiya lokushayela, ngaleyo ndlela ishayela i-rotor ye-steam turbine generator ukuze ijikeleze.
Lapho i-rotor ye-steam turbine iphumule, ilungu elislayidayo lisendaweni emaphakathi efile yokugenca, futhi i-pawl inweba futhi ivale izinyo le-ratchet. Lapho isikelemu nesondo lesikelemu lizungeza, isondo lezikelemu lishayela igiya le-helical (amazinyo angaphakathi) ukuze lijikeleze ndawonye. Ngalesi sikhathi, ngenxa ye-inertia ye-ratchet kanye ne-rotor ngenxa yezidladla (4 isiyonke), izingxenye ezishelelayo azikwazi ukulandela igiya le-helical (amazinyo angaphakathi) Zungezisa ndawonye, kodwa zingahamba kuphela isiqondiso se-axial (ibheke ngase-axial). ikhala). Ngemuva kwalokho, igiya langaphakathi (izinyo eliqondile) kumameshi elungu elishelelayo elinegiya langaphandle eligxilwe ku-shaft yangaphandle ye-rotor ye-steam turbine, i-pawl ne-ratchet iyakhishwa, futhi igiya lezikelemu lishayela igiya langaphandle ngegiya le-helical. kanye nelungu elislayidayo ukuze lizungezise i-rotor ize ifike Isivinini esilinganiselwe sokunyakaziswa kwe-steam turbine. Uma ucezu olushelelayo luya kwesokunxele luya phezulu, amafutha aphuma kancane kancane ku-bafa ukuvimbela ucezu olushelelayo kanye nokuphela ukuthi kuhlikihlwe.
Lapho i-turbine yesitimu izungeza, ijubane le-steam turbine lingaphezulu kwejubane lokukhenceza. I-torque ehlehlayo ekhiqizwa yilo mehluko wesivinini iphusha ingxenye eslayidayo ukuthi iye kancane iye kwesokudla ku-axial direction. Igiya langaphakathi engxenyeni eshelelayo lihlukaniswa negiya langaphandle, futhi i-pawl Iphinde yatholakala ku-ratchet, njengoba umehluko phakathi kwejubane lokukrazula kanye nesivinini se-steam turbine ukhula kancane kancane, ilungu elislayidayo lihamba kahle liye kwesokudla. Uma isivinini se-steam turbine sikhulu kuno-140 rpm, i-pawl izohoxisa futhi ikhiphe izinyo le-ratchet ngaphansi kwesenzo samandla angalingani we-centrifugal kuzo zombili iziphetho ze-pawl, futhi i-crank izohoxa ngokuzenzakalelayo.
Uma isethi yejeneretha ye-steam turbine inqanyuliwe, injini ye-crank kagesi iqala ukusebenza ngokushesha. Lapho ijubane le-rotor ye-turbine ye-steam lehla lifika ku-140 rpm, ingxenye ye-ratchet ye-pawl iphinda inwebe ukuze imelane namazinyo e-ratchet. Uma ijubane le-steam turbine lehla lifinyelela ku-54 rpm, okufana nejubane lokuvinjwa, ingxenye eshelelayo ihambela kwesokunxele iye endaweni yokusebenza, futhi amagiya angaphakathi nangaphandle axhumeke kahle.
