Kukolopa ndi kugaya kwa kalozera tchire ndi thrust chitsamba chaching'ono cha hydraulic turbine ndi njira yofunika kwambiri pakukhazikitsa ndi kukonza malo ang'onoang'ono opangira mphamvu yamadzi.
Zambiri mwama turbine ang'onoang'ono opingasa a hydraulic alibe mawonekedwe ozungulira komanso ma thrust pads alibe ma bolt oletsa kulemera.Monga momwe tawonetsera pachithunzichi: A ndi mawonekedwe a aspheric;B si anti weight bolt, ndipo thrust pad imakanikizidwa mwachindunji pamafelemu a pad.Zotsatirazi ndizo makamaka kulankhula za njira, masitepe ndi zofunikira zokwapula ndi kuyika mawonekedwe apangidwe awa.
1. Zida zokonzekera ndi makona atatu ndi mwala wamafuta wambali ziwiri.Kutalika kwa kubweza katatu kumatha kusinthidwa malinga ndi zizolowezi zanu.Nthawi zambiri, ndi koyenera kugwiritsa ntchito 6-8 koloko.Kubwezeretsa kwakale kwa katatu kungathenso kusinthidwa.Ngati ndi kotheka, mutha kugwiritsanso ntchito chitsulo chakumapeto kugunda mpeni umodzi kapena awiri, womwe ndi wosavuta kukwapula.The akhakula akupera wa triangular kubwerera kamodzi ikuchitika pa akupera gudumu.Pakupera, ziyenera kukhazikika bwino ndi madzi kuti zisapitirire katatu kuti zisatenthe ndi kufewetsa annealing.Kugaya bwino kumachitika pamwala wamafuta kuti muchotse ming'alu yabwino kwambiri ndi ma burrs omwe amasiyidwa panthawi yopera.Pakupera bwino, mafuta a injini (kapena mafuta a turbine) ayenera kuwonjezeredwa kuziziritsa.Konzani tebulo loletsa ndi kutalika koyenera.Chowonetsera chikhoza kusakanikirana ndi inki ya utsi ndi mafuta a turbine kapena kusindikizidwa kofiira.
2. Kuyeretsa, kuchotsa ndi kuchotsa.Chovalacho chidzaphwanyidwa ndikuphwanyidwa musanayambe kukwapula.Makamaka, kuphatikizika kwa chitsamba chowongolera chitsamba, malo ophatikizika ophatikizika ndi malo otsetsereka a pad thrust pad ayenera kutsukidwa mosamala.
3. Kukwapula kwa chitsamba chobereka.Choyamba, shaft yayikulu ya turbine iyenera kusanjidwa ndikukhazikika, (mulingo ≤ 0.08m / M) kuteteza nsapato kuti zisakulidwe kukhala mawonekedwe a taper.Pang'onopang'ono komanso molingana jambulani malo onse okhala ndi mpeni wamakona atatu kuti muchotse mchenga ndi zonyansa zomwe zimayikidwa pamtunda.Zonyansa zomwe zatsekeredwa kwambiri mu alloy yonyamula ziyenera kusankhidwa kuti zisasokoneze mtundu wa scraping pad.
Mukamaliza kuyeretsa bukuli, gwirani chitsamba chomwe chili ndi chitsamba pamagazini, konzani pini, tsekani wononga, ndi kuyeza kuphatikizika kwa chitsamba ndi kusiyana pakati pa Chitsamba ndi magazini pogwiritsa ntchito chida choyezera kuti muwone makulidwe ake. pepala lamkuwa lophatikizidwa pamwamba (padding ndi yokonza mtsogolo).- Nthawi zambiri, pedi yamkuwa imakhala yosanjikiza kawiri, ndipo pafupifupi 0.10 ~ 0.20mm ikhoza kuwonjezeredwa.Mfundo yodziwira makulidwe onse a pad ndikusiya chiwongola dzanja cha 0.08 ~ 0.20 pa chitsamba chobala;Kumbali imodzi, khalidwe lopukuta liyenera kutsimikiziridwa, kumbali ina, ntchito yolemba matayala iyenera kuchepetsedwa momwe zingathere.
Ikani pepala lamkuwa lodulidwa pamtunda wa chitsamba chonyamula, gwirani tchire ziwiri zonyamula pamagazini, sungani zomangira, tembenuzani chitsamba ndikuchipera.Ngati sichingasinthidwe, chotsani chitsamba chonyamuliracho, chitsekereni pakati pa nyuzipepala, ikani pamanja, perani mmbuyo ndi mtsogolo motsatira njira ya tangent, ndikukumbatirani ndi kupera pamene pali kusiyana pakati pa chitsamba chonyamula ndi. magazini.Pambuyo popera, gawo lolumikizana ndi tile pamwamba lidzawonetsa zakuda ndi zowala, ndipo gawo lapamwamba lidzakhala lakuda koma losawala.Dulani gawo lakuda ndi lowala ndi kubwereranso katatu.Pamene mawanga akuda owala sakuwonekera, gwiritsani ntchito mawonekedwe owonetsera pamagazini musanayambe kugaya.Pewani ndi kukwapula mobwerezabwereza mpaka kukhudzana ndi chilolezo pakati pa pamwamba ndi magazini zikwaniritse zofunikira.Nthawi zambiri, matailosi onse akuyenera kulumikizidwa panthawiyi, koma palibe malo olumikizirana ambiri;Chilolezo chayamba kuyandikira zofunikira, ndipo pali chololeza cha 0.03-0.05mm.Pewani zipolopolo zonyamula mbali zonse za flywheel motsatana.
4. Kukatula pa thrust pad.Chifukwa chopondera chopondera nthawi zambiri chimakandidwa panthawi yoyendetsa ndi kusungidwa, pamakhala ma burrs pamwamba pa pedi, ndiye choyamba kumamatira sandpaper ya metallographic pagalasi, ndikukankhira kutsogolo ndi mtsogolo pa sandpaper kangapo.Panthawi yopera, sungani matayala amtundu wofanana ndi mbale ya galasi, ndipo nthawi zopera ndi kulemera kwa tile iliyonse ndizofanana, apo ayi makulidwe a kukankhira kumasiyana kwambiri, kuonjezera ntchito yotupa.
Pukutani mbale ya galasi ndi pad pamwamba, kanikizani chopondera pa galasi la galasi, perani mmbuyo ndi mtsogolo kwa maulendo oposa khumi molingana ndi kuzungulira kwa pad ndi galasi, ndikuchotsani choponderapo kuti mukolole.Pambuyo pazigawo zonse zonyamula zimagwirizana bwino ndi galasi la galasi, kubereka kungathe kusonkhanitsidwa
5. Kukhala ndi kuphatikiza ndi kukwapula bwino.Choyamba, ikani mpando wonyamulira woyeretsedwa m'malo mwake (pa maziko, zomangira zomangira za mpando wonyamula zimatha kulumikizidwa mndandanda koma osamangika), ikani chitsamba chotsika pansi pampando wonyamulira, ndikukweza pang'onopang'ono shaft yayikulu mumayendedwe. chitsamba, sinthani mpando wonyamulira poyesa chilolezo cha chitsamba, kuti mzere wapakati wa chitsamba chonyamula mbali zonse za flywheel ukhale wowongoka (mawonedwe apamwamba: zolakwika zonse ≤ 2 mawaya), ndi malo akutsogolo ndi kumbuyo. ali oyenerera (khushoni idzawonjezedwa pamene kusiyana kwa msinkhu wa mpando wonyamula kuli kwakukulu), ndiyeno kutseka zomangira za mpando wonyamula.
Pamanja tembenuzani flywheel kangapo mokhotakhota, chotsani chitsamba ndikuyang'ana kugawidwa kwa malo olumikizana ndi chitsamba.Pamene mbali yonse yonyamulirayo ilumikizana bwino ndipo chitsamba chonyamula chitsamba chikukwaniritsa zofunikira (chilolezocho chidzagwirizana ndi zofunikira za chojambulacho. Ngati sichinawonetsedwe, tengani 0.l ~ 0.2% ya m'mimba mwake kuti mukakolole. Mfundo zazikuluzikulu zokhala ndi fayilo yamakona atatu ndikuchepetsa zowirira; chitsanzo cha mpeni nthawi zambiri chimakhala chojambula, chomwe chimagwiritsidwa ntchito kuti chisungidwe ndikuyendetsa mafuta a turbine. ~ 70 ° pakatikati pa chitsamba chotsika, ndipo mfundo 2-3 pa centimita imodzi ndiyoyenera, osati mochuluka kapena pang'ono.
Tsukani poponyeramo ndi nsalu yoyera.Zikatha, onjezerani mafuta opaka pang'ono pa cholozera cholozera, tembenuzani gudumu lakuwulukira, ndipo onjezerani axial thrust kuti mupere pad thrust pad ndi mbale yagalasi molingana ndi malo ake enieni.Chongani padilo lililonse (malo a phala lopondereza ndi dzenje loyezera kutentha ndipo pafupi ndi malo ophatikizika amakhazikika), yang'anani pamtunda, pezaninso cholumikizira, ndikugayanso pini kumbuyo kwa pediyo ndi nsalu yopumira ( kugaya kumakhala kochepa kwambiri, komwe kumayesedwa ndi micrometer yamkati yamkati kapena vernier caliper, yomwe ikufanizidwa ndi pedi yochepetsetsa).Kumbali imodzi, cholinga chake ndikupangitsa kuti padiyo ikhale yolumikizana bwino ndi mbale yagalasi, kumbali ina, kuti "yokhuthala" ikhale yocheperako.Ndikofunikira kuti ma 8 thrust pads onse azilumikizana bwino pamalo enieni.Nthawi zambiri, cholumikizira cha turbine yaying'ono yopingasa ndi yaying'ono ndipo katundu wake ndi wocheperako, kotero kuti padiyo sikhoza kukandidwa.
6. Kupala bwino.Pambuyo kunyamula lonse kuikidwa m'malo ndi konkire kuumitsa, kuwonjezera axial kukankha kuti atembenuke, ndi kukonza ndi scrape malinga ndi kukhudzana kwenikweni pakati kubala PAD ndi kukankhira PAD kukwaniritsa zofunika zojambula ndi specifications.
A longitudinal mafuta poyambira adzatsegulidwa mbali zonse za olowa chitsamba kubala kapena mbali imodzi (mafuta mbali mbali), koma osachepera 8mm mitu ayenera kusungidwa pa malekezero onse awiri kupewa kutaya mafuta mafuta mbali zonse.Kulowera kwamafuta kwa pad yokankhira nthawi zambiri kumaphatikizapo kutsika kwa 0.5mm ndipo m'lifupi ndi pafupifupi 6 ~ 8mm.Chitsamba chonyamulira ndi thrust pad zimayeneretsedwa kokha pambuyo pokwapula bwino
