Pansi pa kukakamizidwa kawiri kwa kukhazikitsa mwachangu komanso mliri, kuperekedwa kwa mayendedwe amphamvu amphepo kukusoweka, mwayi ndi zovuta zakumaloko.

M’dzuŵa lotentha kwambiri, makina a malo opangira magetsi a mphepo a fakitale yodziwika bwino yonyamula katundu m’nyumba anabangula, ndipo sukuluyo inali yotanganidwa. Ogwira ntchito pamalopo anali akuthamangira kulamula kuti awonetsetse kufunikira kwa opanga makina opangira magetsi amphepo am'nyumba ndi akunja.

Komabe, panthawi imodzimodziyo kuti mphamvu ya mphepo "kuyika mofulumira" yabweretsa kuwonjezeka kofulumira kwa kufunika kobereka, mliriwu wakhudza kupanga kwabwino kwa opanga obereka kunyumba ndi kunja. Miyezo yayikulu ya mphamvu yamphepo yakhala ikusowa.

Luo Yi, wogwira ntchito mkati mwa Luo Shao (wodziwika bwino pano pa pempho la wofunsayo) adauza atolankhani kuti, kwenikweni, kulamula kwa mayendedwe amphepo amphamvu awonjezeka kwambiri kuyambira theka lachiwiri la chaka chatha, ndipo ena apamwamba kwambiri. spindles panopa akukhudzidwa ndi mliri. Ma Bearings adasamutsidwanso kwa opanga zonyamula zapakhomo kuti ayambe kufufuza ndi chitukuko ndi kupereka batch yaying'ono.

Pansi pa zovuta ziwiri za kukhazikitsa mwachangu komanso mliri, opanga magetsi apanyumba akukumana ndi zovuta ...

Maoda a fakitale yapanyumba adakwera kwambiri

Ma mayendedwe amphepo ndi chimodzi mwazinthu zofunikira zothandizira ma turbines amphepo. Osangoyenera kunyamula katundu wambiri, komanso kukhala ndi moyo wazaka zosachepera 20 ngati injini yayikulu. Chifukwa chake, luso laukadaulo la mayendedwe amphepo ndilapamwamba, ndipo limazindikiridwa ndi makampani ngati makina opangira mphepo amtundu wamba. Chimodzi mwa zigawo.

Mphepo yonyamula mphamvu yamphepo ndiyotengera yapadera, makamaka kuphatikiza: kunyamulira, kunyamula phula, kunyamula shaft yayikulu, kunyamula ma gearbox, kunyamula jenereta. Zina mwa izo, zonyamula ma jenereta ndizopangidwa ndi chilengedwe chonse chokhala ndi ukadaulo wokhwima.

Makampani omwe akunyamula mphamvu zamphepo mdziko langa makamaka amaphatikizapo shaft ya matailosi, shaft ya Luo, zitsulo za Dalian, ukadaulo wofufuza za shaft, Tianma, ndi zina zambiri, ndipo mphamvu yopangira mabizinesi omwe ali pamwambawa imangokhazikika pamakwerero amiyala ndi mayendedwe otsika okhala ndi ukadaulo wochepa.

Ponena za ma spindle makiyi, makampani opanga nyumba makamaka amapanga magiredi a 1.5 MW ndi 2.x MW, pomwe ma spindle amtundu wa MW amadalira kwambiri kuchokera kunja.

Kuyambira chaka chatha, kufunikira kwa msika wamagetsi amagetsi akuchulukirachulukira. Okhudzidwa ndi mliri wapadziko lonse chaka chino, opanga zoberekera zapakhomo alandira malamulo ndikulandira manja ofewa.

Tengani Gulu la Waxshaft monga chitsanzo. Kuyambira Januware mpaka Meyi 2020, ndalama zochokera kubizinesi yayikulu yonyamula makina amphepo zidakwera ndi 204% munthawi yomweyi chaka chatha.

Komabe, wina wamkati mwa gulu la shaft ya matailosi adati masipilo a spindle akhala akusowa chaka chino, makamaka ma spindle a megawatts akulu.

Pali malingaliro m'makampani omwe mayendedwe akuluakulu m'tsogolomu komanso ngakhale mabwalo akuluakulu a megawati adzalepheretsa kutumiza kwa opanga makina opangira mphepo.

M'mbuyomu, pamsonkhano wapaintaneti wokhudza chitukuko chapadziko lonse lapansi chamakampani opanga mphamvu zakunyanja zakunyanja pansi pa mliri, Tian Qingjun, wachiwiri kwa purezidenti wa Yuanjing Energy, adanenanso kuti ndi opanga ochepa chabe akunja monga Schaeffler ndi SKF omwe amatha kupanga zazikulu zazikulu. mayendedwe, koma zotulutsa zake zonse chaka chino ndi pafupifupi ma seti 600, ndipo zidzagawidwa pamsika wapadziko lonse lapansi wamagetsi akunyanja.

Panthawi imodzimodziyo, mliri wa mliri wa ku Ulaya utatha, Schaeffler, SKF ndi mafakitale ena onyamula katundu ku Ulaya akhudzidwa kwambiri, makamaka ku Ulaya. Ena ogulitsa zinthu zopangira akuchokera ku Italy.

Zitha kunenedwa kuti mphamvu yonyamula spindle yamakono ili kutali ndi kukwaniritsa zosowa zamakampani opanga mphamvu zamphepo.

Localization of main bearings? Ndi mwayi komanso zovuta

Munthu wina wamakampani opanga mphamvu zamphepo yemwe sanafune kutchulidwa dzina adawulula kuti pakakhala kuchepa kwa ma bearing amphamvu amphepo, opanga makina opangira magetsi amphepo akugwiritsa ntchito mayendedwe apanyumba, makamaka ma shaft a matailosi ndi ma Luo shafts.

Poyankha, mtolankhaniyo adafunsa a Li Yi kuti atsimikizire. Iye adati palidi ena opanga mainframe omwe amasankha ma bearings ochokera kunja chaka chonse ndipo ayamba kusintha m'malo mwanyumba.

Kukhazikika kokwanira kwa mayendedwe amphamvu amphepo ndi njira yayitali. Omwe ali mkati mwazitsulo zomwe tazitchula pamwambapa amakhulupirira kuti chinthu chachikulu chomwe chimalimbikitsa kukhazikika masiku ano ndi kusowa kwa mayendedwe akuluakulu.

Zimamveka kuti shaft ya Luo ndi shaft ya matailosi ndizinthu zambiri, zomwe zimakhala ndi chidziwitso pakupanga mayendedwe amphepo zamphamvu zamphepo, komanso zimakhala ndi zaka zambiri zogwirira ntchito, kotero mumayendedwe awa othamanga akhoza kukhala oyamba kutenga. kulamula kwa mayendedwe amphamvu amphepo.

Komabe, omwe ali pamwambawa adanenabe kuti pali kusiyana pakati pa zopanga zopota zapakhomo ndi mayiko akunja potengera kapangidwe kake, kayeseleledwe kantchito komanso kudzikundikira.

Mtolankhaniyo adaphunzira kuti ena opanga mainframe adzalowererapo opanga zonyamula kuchokera pakufufuza koyambirira ndi chitukuko akasankha kusintha ma bere a spindle ndi malo. Panthawi imodzimodziyo, adzatumiza oyang'anira kuti azitsatira ndondomekoyi.

Malinga ndi Li Yi, mgwirizanowu unali wosowa kwambiri m'mbuyomu, ndipo udawonekera pambuyo poyambira kulanda.

Chifukwa pakali pano, ambiri mphepo mphamvu khamu opanga ganyu zoweta ndi akunja kubala akatswiri ndi luso ogwira ntchito, amene amalimbikitsa mphepo mphamvu khamu opanga ndi zoweta akatswiri kubala opanga kukhala zozama, moyandikira ndi ogwira mafotokozedwe luso ndi kuwombola mu siteji oyambirira. ya mphamvu yamphepo yokhala ndi R&D Mgwirizanowu walimbitsa chidaliro cha mbali zonse ziwiri, ndipo panthawi imodzimodziyo, kudzera mu kugawana ndi kutchulidwa kwa malingaliro apangidwe ndi malingaliro apangidwe, mapangidwe a mayendedwe amphamvu zamphepo ndi injini zazikulu zakhala zokongoletsedwa bwino. Amakhulupirira kuti mgwirizano woterewu wowona mtima komanso wothandizana nawo umathandizira makampani opanga mphamvu zamagetsi kupita patsogolo limodzi.

Kwa kutanthauzira kwa ma beya akuluakulu amagetsi amphepo, ambiri omwe ali m'makampani amakhulupirira kuti ili ndi lupanga lakuthwa konsekonse, lomwe ndi mwayi komanso chovuta pamayendedwe apanyumba.
