Kukwenya uye kukuya kwegwara rinotakura gwenzi uye thrust gwenzi rediki hydraulic turbine inzira yakakosha mukumisikidza uye kugadzirisa kwechiteshi chidiki chehydropower.
Mazhinji emabearings ediki akatwasuka hydraulic turbines haana spherical chimiro uye ma thrust pads haana anti huremu mabhaudhi.Sezvinoratidzwa mumufananidzo: A is aspheric structure;B haisi anti huremu bhaudhi, uye iyo yekusundira padhi inodzvanywa yakananga padhidhi.Izvi zvinotevera zvinonyanya kutaura nezve nzira, matanho uye zvinodiwa zvekukwenya uye kuiswa kweiyi fomu yemaitiro.
1. Zvishandiso zvekugadzirira ndezvitatu uye dombo remafuta rakapetwa kaviri.Hurefu hwekudzokera shure hunogona kugadziriswa maererano nemaitiro ako pachako.Kazhinji, zvakakodzera kushandisa 6-8 o'clock.Iyo yekare triangular kudzoserwa kumashure inogona zvakare kugadziridzwa.Kana zvichibvira, iwe unogona zvakare kushandisa chitubu simbi kurova rimwe kana maviri banga rakatsetseka, iro riri nyore kukwenya padhi yekurovesa.Kukuya kwakakasharara kwekudzokera kumashure kunoitwa pagumbo rekukuya.Panguva yekukuya, inofanira kunyatsotonhodzwa nemvura kudzivirira kuti triangular idzoke kubva pakupisa uye kupfava kweannealing.Kukuya kunoitwa padombo reoiri kubvisa madhindi nemabura akasara panguva yekukuya.Panguva yekukuya zvakanaka, oiri yeinjini (kana turbine mafuta) inowedzerwa kuti itonhodze.Gadzirira tafura yekusungirira nehurefu hwakakodzera.Chiratidziro chinogona kusanganiswa neingi yehutsi nemafuta eturbine kana kudhindwa tsvuku.
2. Kuchenesa, kubvisa uye kubvisa.Kutakura kuchaderedzwa uye kubviswa pamberi pekukweshwa.Kunyanya, kusanganiswa kwepamusoro pegwara rinotakura gwenzi, bhanhire rinotakura pamusoro pekutakura uye nzvimbo yekutakura yepedhi yekukanda inofanira kunyatsocheneswa.
3. Kukweva kwakashata kwegwenzi rinobereka.Chekutanga, iyo huru shaft yeturbine ichagadziriswa uye yakagadziriswa, (levelness ≤ 0.08m / M) kudzivirira shangu kuti isakwekwe kuita taper shape.Zvinyoro uye zvakaenzana purani nzvimbo yese inotakura nebanga retriangular kuti ubvise jecha uye tsvina inonamirwa kune inotakura nzvimbo.Tsvina yakavharirwa zvakadzika mubearing alloy ichatorwa kuti isakanganisa kunaka kwe scraping pad.
Mushure mekuchenesa jenari, bata gidhi rine gwenzi pajenari, gadzirisa pini yenzvimbo, kiya sikuruu, uye woyera nzvimbo yakasanganiswa yegwenzi rinotakura uye mukaha uripo pakati peBush nejenari nejeji yekunzwa kuona ukobvu hwe. pepa remhangura rakawedzerwa pamusoro pechiso chakabatanidzwa (padding ndeyekugadzirisa mune ramangwana).- Kazhinji, iyo pedhi yemhangura ine mbiri-layer, uye inenge 0.10 ~ 0.20mm inogona kuwedzerwa.Nheyo yekutarisa huwandu hwese hwepadhi ndeyekusiya mvumo yekukwenya ye0.08 ~ 0.20 yegwenzi rinotakura;Kune rumwe rutivi, hutano hwekutsvaira hunofanira kuvimbiswa, kune rumwe rutivi, basa rekutsvaira tile rinofanira kuderedzwa zvakanyanya sezvinobvira.
Isai pepa remhangura rakachekwa panzvimbo yakabatanidzwa yegwenzi rinotakura, bata mabhurashi maviri anotakura pajenari, simbisa zvigadziriso zvekugadzirisa, shandura gwenzi rinotakura uye uchikuya.Kana isingakwanisi kutenderedzwa, bvisa gwenzi rinobereka, risungirire nepakati pajenari, ridzvanye neruoko, rikuye neseri uchitevedza tangent direction, wobva wambundikira nekukuya kana paine mukaha pakati pegwenzi rinotakura. bhuku.Mushure mekugaya, chikamu chekubatanidza chetairi chepamusoro chicharatidza dema uye chakajeka, uye chikamu chepamusoro chichave chakasviba asi chisina kujeka.Cheka chikamu chitema uye chakajeka chine triangular setback.Kana mavara matema akajeka asina kuoneka, shandisa dhizaini yekuratidzira pajenari usati wakuya.Kukuya uye kukwenya kasingaperi kusvikira kubatwa uye kucheneswa pakati penzvimbo inotakura uye magazini inosangana nezvinodiwa.Kazhinji kutaura, iyo tile yese yepamusoro inofanirwa kubatwa panguva ino, asi hapana yakawandisa yekusangana nzvimbo;Iyo clearance yatanga kuswedera kune zvinodiwa, uye pane scraping allowance ye0.03-0.05mm.Nyora makanda anotakura pamativi ese eflywheel zvakateerana.
4. Kukwenya kwepadhi yekurovera.Nekuti iyo yekurovera pedhi inowanzokweshwa panguva yekufambisa nekuchengetedza, pachange paine mabhura pamusoro pepedhi, saka tanga wanamatira metallographic sandpaper pagirazi ndiro, uye sunda pedhi yekurovera kumashure nekudzoka pajecha kakati wandei.Panguva yekukuya, chengetedza tile yepamusoro yakaenzana negirazi regirazi, uye nguva dzekukuya uye uremu hwetirairi imwe neimwe yakafanana, kana zvisina kudaro kuwanda kwekukanda kunosiyana zvakanyanya, kuwedzera basa rekutsvaira.
Pukuta ndiro yegirazi uye pedhi pamusoro, dzvanya pedhi yekurovera pagirazi ndiro, ikuya nekudzoka shure kwekanopfuura kagumi zvichienderana nekutenderera kwepadhi uye ndiro yegirazi, uye bvisa purasita yekukwenya.Mushure mokunge nzvimbo dzose dzakatakura dzakabatana zvakanaka negirazi ndiro, kutakura kunogona kuunganidzwa
5. Kutakura gungano uye kukweshwa kwakanaka.Kutanga, isa chigaro chekutakura chakacheneswa panzvimbo (panheyo yenheyo, zvigadziriso zvechigaro chekutakura zvinogona kubatanidzwa mumutsara asi kwete kusimbiswa), isa gwenzi rezasi rinotakura mukati mechigaro chekutakura, zvinyoronyoro simudza shaft yakakura mukati mekutakura. gwenzi, gadzirisa chigaro chekutakura nekuyera kubviswa kwegwenzi rinotakura, kuitira kuti mutsara wepakati wegwenzi rinotakura pamativi ese eflywheel uri munzira yakatwasuka (yepamusoro maonero: general kukanganisa ≤ 2 waya), uye nzvimbo dzepamberi neshure. akakodzera (cushion ichawedzerwa kana kusiyana kwekukwirira kwechigaro chekutakura kwakakura), uye wozovhara screwing screw yechigaro chekutakura.
Nemaoko tenderedza iyo flywheel kune akati wandei, bvisa gwenzi rinotakura uye tarisa kugoverwa kweanotakura bush kuonana nzvimbo.Kana iyo yese inotakura nzvimbo ikasangana zvakanaka uye gwenzi rinotakura gwenzi rinoenderana nezvinodiwa (kubvisa kunoenderana nezvinodiwa zvekudhirowa. Kana zvisina kuratidzwa, tora 0.l ~ 0.2% yejenari dhayamita yekukwenya. Scrape mapoinzi mahombe ane triangular faira uye anonatsa mapoinzi akakora; banga patani rinowanzoita strip, iro rinoshandiswa kufambisa kuchengetedza uye kutenderera kwemafuta eturbine. Chinodiwa ndechekuti mapoinzi ekusangana akagovaniswa zvizere mukati meiyo kona inosanganisirwa ye60 °. ~ 70 ° pakati pegwenzi rezasi rinotakura, uye 2-3 mapoinzi pa square centimita yakakodzera, kwete yakawandisa kana kudiki.
Chenesa pedhi yekurovera nejira jena.Mushure mekunge yave panzvimbo, wedzera mafuta mashoma ekuzora kune gwara rinotakura padhi, tenderedza vhiri rekubhururuka, uye wedzera axial svutugadzike yekukwenya padhi uye ndiro yegirazi zvinoenderana nenzvimbo yayo chaiyo.Maka padhi yega yega (nzvimbo yepedhi yekumhanyisa ine gomba rekuyeresa tembiricha uye padhuze nepamusoro pemusanganiswa yakagadziriswa), tarisa padhi repamusoro, tsvaira padhi yekubata zvakare, uye zvakaenzana kugaya pini kuseri kwepedhi nejira rinoputika ( kugaya kwakaderera zvakanyanya, iyo ichayerwa nemukati dhayamita micrometer kana vernier caliper, iyo inofananidzwa neyakaonda pad).Kune rimwe divi, chinangwa ndechekuita kuti padhi yepamusoro ibatane zviri nani negirazi ndiro, kune rimwe divi, kuita iyo "yakakora" yekukanda pad diki.Izvo zvinodikanwa kuti ese 8 thrust pads ave nekusangana kwakanaka munzvimbo chaiyo.Kazhinji kutaura, iyo pedhi yekuchinjisa yeturbine diki idiki uye mutoro idiki, saka iyo padhi yepamusoro haigone kukweshwa.
6. Kukorobha zvakanaka.Mushure mekutakura kwese kwaiswa panzvimbo uye kongiri yaomesa, wedzera axial thrust kutendeuka, uye gadzirisa uye kukwenya zvinoenderana nekusangana chaiko pakati pekubereka pad uye thrust pad kusangana nezvinodiwa zvekudhirowa uye zvakatemwa.
Iyo longitudinal mafuta groove ichavhurwa pamativi ese ekubatanidzwa kwegwenzi rinotakura kana kune rimwe divi (oiri rekupa divi), asi inokwana 8mm misoro ichachengeterwa kumigumo yese kudzivirira kurasikirwa kwemafuta ekuzora kubva kumativi ese.Kupinza kwemafuta kwepush pad kazhinji kunosanganisira 0.5mm kudzika uye hupamhi hunenge 6 ~ 8mm.Iyo gwenzi rinotakura uye thrust pad zvinofanirwa chete mushure mekukweshwa kwakanaka
