Ukukhuhla kanye nokugaywa kwesihlahla esithwala umhlahlandlela kanye ne-thrust bush ye-hydraulic turbine encane kuyinqubo ebalulekile ekufakweni nasekulungisweni kwesiteshi esincane sokuphehla ugesi ngamanzi.
Iningi lama-bearings ama-turbine asebenza ngogesi amancane avundlile awanawo isakhiwo esiyindilinga futhi ama-thrust pads awanawo ama-anti weight bolt.Njengoba kuboniswe emfanekisweni: U-A uyisakhiwo se-aspheric;U-B akayona ibhawudi elilwa nesisindo, futhi i-thrust pad icindezelwa ngokuqondile kufreyimu yephedi.Okulandelayo ikakhulukazi ukukhuluma ngezindlela, izinyathelo kanye nezidingo zokukhuhla nokufakwa kwaleli fomu lesakhiwo.
1. Amathuluzi okulungiselela angunxantathu kanye ne-oilstone enezinhlangothi ezimbili.Ubude bokubuyela emuva kukanxantathu bungalungiswa ngokuya ngemikhuba yakho.Ngokuvamile, kufanelekile ukusebenzisa ihora lesi-6-8.Ukuhlehla kukanxantathu omdala nakho kungashintshwa.Uma kungenzeka, ungasebenzisa futhi i-spring steel ukushaya ummese owodwa noma emibili eyisicaba, okulula kakhulu ukuklwebha i-thrust pad.Ukugaya okungalungile kokuhlehliswa kwe-triangular kwenziwa esondo lokugaya.Ngesikhathi sokugaya, kufanele zipholiswe ngokugcwele ngamanzi ukuze kuvinjwe ukuhlehla kukanxantathu ekushiseni nasekuthobeni kwe-anneal.Ukugaya kahle kwenziwa phezu kwe-oilstone ukuze kukhishwe izibonda ezicolekile kanye nama-burrs asele ngesikhathi sokugaya.Ngesikhathi sokugaya, uwoyela wenjini (noma uwoyela we-turbine) uzofakwa ukuze uphole.Lungiselela itafula lokubopha ngobude obufanele.I-ejenti yokubonisa ingaxutshwa noyinki wentuthu namafutha e-turbine noma okubomvu okuphrintiwe.
2. Ukuhlanza, ukususa nokususa.Umuthi uzosuswa futhi ususwe ngaphambi kokutshala.Ikakhulukazi, inhlanganisela yobuso behlathi eliphethe isiqondiso, indawo ehlangene ehlangene ye-bearing kanye ne-bearing surface ye-thrust pad izohlanzwa ngokucophelela.
3. Ukukhuhla okuqinile kwesihlahla esithwalayo.Okokuqala, i-shaft eyinhloko ye-turbine kufanele ilinganiswe futhi ilungiswe, (izinga ≤ 0.08m / M) ukuvimbela isicathulo ukuthi singaklwejwa sibe yisimo se-taper.Gcoba ngobumnene nangokulinganayo yonke indawo yokuthwala ngommese ongunxantathu ukuze ususe isihlabathi nokungcola okunamathiselwe endaweni yokuthwala.Ukungcola okuvaleleke ngokujulile ku-alloy ethwalayo kuzokhethwa ukuze kugwenywe ukuthikameza ikhwalithi yephedi lokukhuhla.
Ngemva kokuhlanza ijenali, bamba inkomba enesihlahla kujenali, lungisa iphinikhodi, vala isikulufu, bese ukala indawo ehlanganisiwe yesihlahla esithwalayo kanye negebe phakathi kweBush nejenali ngegeji yokubona ukushuba ishidi lethusi lengezwe endaweni ehlanganisiwe (i-padding ingeyokugcinwa kwesikhathi esizayo).- Ngokuvamile, i-copper pad ine-double-layer, futhi cishe u-0.10 ~ 0.20mm zinganezelwa.Umgomo wokunquma ukushuba okuphelele kwephedi ukushiya isibonelelo sokukhuhla esingu-0.08 ~ 0.20 sesihlahla esithelayo;Ngakolunye uhlangothi, ikhwalithi ye-scraping kufanele iqinisekiswe, ngakolunye uhlangothi, umsebenzi wokukhuhla amathayili kufanele uncishiswe ngangokunokwenzeka.
Beka ishidi lethusi elisikiwe endaweni ehlangene yesihlahla esithwalayo, ubambe izihlahla ezimbili ezithwalayo kumagazini, qinisa izikulufa zokulungisa, ujikeleze isihlahla esithwalayo bese usigaya.Uma ingakwazi ukuphendukiswa, susa isihlahla esithwalayo, usibophe sibe uhhafu kujenali, uyicindezele ngesandla, uyigaye emuva naphambili ngendlela ye-tangent, bese uyigona futhi uyigaye lapho kunegebe phakathi kwesihlahla esithwalayo kanye iphephabhuku.Ngemuva kokugaya, ingxenye yokuxhumana ye-tile surface izobonisa emnyama futhi ekhanyayo, futhi ingxenye ephakeme izoba mnyama kodwa ingakhanyi.Sika ingxenye emnyama nekhanyayo ngokubuyisela emuva kukanxantathu.Uma amabala amnyama akhanyayo engabonakali, sebenzisa ungqimba lwe-ejenti yokubonisa kujenali ngaphambi kokugaya.Gaya futhi ukrwele ngokuphindaphindiwe kuze kube yilapho ukuthintana nokuvunyelwa phakathi kwendawo ephethe kanye nejenali kuhlangabezana nezidingo.Ngokuvamile, yonke indawo yethayili kufanele ithintwe ngalesi sikhathi, kodwa awekho amaphuzu amaningi okuxhumana;Ukukhishwa sekuqalile ukusondelana nezidingo, futhi kunemvume yokukhuhla engu-0.03-0.05mm.Khwebula amagobolondo athwalayo nhlangothi zombili ze-flywheel ngokulandelanayo.
4. Ukukhuhla i-thrust pad.Ngenxa yokuthi i-thrust pad ivame ukuklwejwa ngesikhathi sokuthutha nokugcinwa, kuzoba nama-burrs endaweni ye-pad, ngakho-ke qala unamathisele i-metallographic sandpaper epuleti lesibuko, bese uphusha i-thrust pad uye le phambili naphambili ku-sandpaper izikhathi ezimbalwa.Ngesikhathi sokugaya, gcina i-tile surface ihambisana nepuleti lesibuko, futhi izikhathi zokugaya nesisindo sethayela ngalinye ziyafana, ngaphandle kwalokho ubukhulu be-thrust buhluka kakhulu, okwandisa umsebenzi wokukhuhla.
Sula ipuleti lesibuko nendawo yephedi, cindezela i-thrust pad epuleti lesibuko, uyigaye uye phambili naphambili izikhathi ezingaphezu kweziyishumi ngokuya ngendlela yokuzungezisa yephedi kanye nepuleti lesibuko, bese ususa i-thrust pad ukuze uyikhuhle.Ngemuva kokuthi zonke izindawo ezithwalayo zithintana kahle nepuleti yesibuko, ukuthwala kungaqoqwa
5. Ukuhlanganisa ukuhlanganisa nokuklwebha kahle.Okokuqala, faka isihlalo sokuthwala esihlanziwe endaweni (ohlakeni lwesisekelo, izikulufo zokulungisa zesihlalo esithwalayo zingaxhunywa ochungechungeni kodwa zingaqiniswa), faka isihlahla esingaphansi esinesihlalo sokuthwala, uphakamise ngobumnene i-shaft enkulu endaweni yokuthwala. bush, lungisa isihlalo esithwalayo ngokulinganisa ukuvunyelwa kwesihlahla esithwalayo, ukuze umugqa ophakathi nendawo wesihlahla esithwalayo ezinhlangothini zombili ze-flywheel ube umugqa oqondile (ukubuka okuphezulu: iphutha elijwayelekile ≤ izintambo ezi-2), kanye nezikhundla zangaphambili nangemuva. zifanelekile (umcamelo uzokwengezwa lapho umehluko wokuphakama wesihlalo esithwalayo mkhulu), bese uvala isikulufu sokulungisa sesihlalo sokuthwala.
Zungezisa i-flywheel ngokuphenduka okuningana, susa isihlahla esithwalayo futhi uhlole ukusatshalaliswa kwamaphoyinti okuxhumana asehlathini.Lapho yonke indawo ethwalayo ithintana kahle futhi ukuphuma kwesihlahla esithwalayo kuhlangabezana nezidingo ngokuyisisekelo (imvume kufanele ihambisane nezidingo zomdwebo. Uma kungabonisiwe, thatha u-0.l ~ 0.2% wedayamitha yejenali ukuze uyikhuhle. Khupha. amaphuzu amakhulu anefayela elingunxantathu futhi anciphise amaphuzu aminyene, iphethini yommese ngokuvamile iwumdweshu, osetshenziselwa ukusiza ukugcinwa nokujikeleza kukawoyela we-turbine. Imfuneko ukuthi izindawo zokuthintana zisakazwe ngokugcwele ngaphakathi kwe-engeli efakiwe engu-60 ° ~ 70 ° phakathi nendawo yesihlahla esithwalayo esiphansi, futhi amaphuzu angu-2-3 ngesentimitha yesikwele afanelekile, hhayi kakhulu noma amancane kakhulu.
Hlanza i-thrust pad ngendwangu emhlophe.Ngemva kokuthi isisendaweni, engeza amafutha okugcoba amancane kuphedi ephethe umhlahlandlela, ujikelezise i-flywheel, bese wengeza i-axial thrust ukuze ugaye i-thrust pad kanye nepuleti lesibuko ngokwendawo yalo yangempela.Maka i-pad ngayinye (indawo ye-thrust pad enembobo yokulinganisa izinga lokushisa futhi eduze nendawo ehlangene ilungisiwe), hlola indawo ye-pad, uphinde usule iphedi yokuxhumana, futhi ngokulinganayo ugaye iphini ngemuva kwephedi ngendwangu e-brasive ( ukugaya kuphansi kakhulu, okuzolinganiswa nge-micrometer yangaphakathi yobubanzi noma i-vernier caliper, eqhathaniswa nephedi elincane).Ngakolunye uhlangothi, inhloso ukwenza i-pad surface ukuthintana kangcono nepuleti lesibuko, ngakolunye uhlangothi, ukwenza i-thrust pad "eminyene" ibe mncane.Kudingeka ukuthi wonke ama-thrust pad angu-8 abe nokuxhumana okuhle endaweni yangempela.Ngokuvamile, i-thrust pad ye-turbine encane evundlile incane futhi umthwalo mncane, ngakho indawo yephedi ayikwazi ukuklwejwa.
6. Ukukhuhla kahle.Ngemuva kokuthi yonke i-bearing ifakwe endaweni futhi ukhonkolo uqina, engeza i-axial thrust ukuze ujike, futhi ulungise futhi usule ngokusho kokuxhumana kwangempela phakathi kwe-bearing pad kanye ne-thrust pad ukuze uhlangabezane nezidingo zemidwebo kanye nokucaciswa.
I-longitudinal groove kawoyela izovulwa ezinhlangothini zombili zokuhlangana kwesihlahla esizalayo noma ohlangothini olulodwa (uhlangothi lokunikezwa uwoyela), kodwa okungenani amakhanda angu-8mm azogcinwa kuzo zombili iziphetho ukuze kugwenywe ukulahleka kwamafutha okugcoba kuzo zombili iziphetho.I-oyili ye-push pad ngokuvamile ihlanganisa u-0.5mm ngaphansi futhi ububanzi bucishe bube ngu-6 ~ 8mm.Isihlahla esithwalayo kanye ne-thrust pad zifaneleka kuphela ngemuva kokuklwelwa kahle
