Padzuwa lotentha kwambiri, makina a malo opangira zida zamagetsi za mphepo a fakitale yodziwika bwino yopangira zida zamagetsi zapakhomo anagwedezeka, ndipo sukuluyo inali yotanganidwa. Antchito omwe anali pamalopo anali kuthamanga kuti apereke maoda kuti atsimikizire kuti opanga zida zamagetsi zapakhomo ndi zakunja akufunikira.
Komabe, panthawi yomweyi pamene "kukhazikitsa mwachangu" kwa mphamvu ya mphepo kwabweretsa kuwonjezeka kwakukulu kwa kufunikira kwa ma bearing, mliriwu wakhudza kupanga kwabwinobwino kwa opanga ma bearing kunyumba ndi kunja. Ma bearing akuluakulu a mphamvu ya mphepo akhala akusowa nthawi zonse.
Luo Yi, wogwira ntchito mkati mwa Luo Shao (dzina lodziwika bwino apa pofunsidwa ndi wofunsa mafunso) adauza atolankhani kuti, kwenikweni, maoda a ma spindle bearings a mphamvu ya mphepo awonjezeka kwambiri kuyambira theka lachiwiri la chaka chatha, ndipo ma spindles ena amphamvu kwambiri pakadali pano akukhudzidwa ndi mliriwu. Ma bearings aperekedwanso kwa opanga ma bearings am'nyumba kuti ayambe kafukufuku ndi chitukuko komanso kupereka zinthu zochepa.
Pansi pa kukakamizidwa kawiri kwa kukhazikitsa mwachangu komanso mliri, opanga magetsi amphepo m'nyumba akukumana ndi mavuto akulu ...
Maoda a mafakitale onyamula ma bearing a m'nyumba akwera kwambiri
Ma bearing a mphamvu ya mphepo ndi chimodzi mwa zida zofunika kwambiri zothandizira ma turbine a mphepo. Sikuti amangofunika kunyamula katundu wolemera kwambiri, komanso amakhala ndi moyo wa zaka zosachepera 20 monga injini yayikulu. Chifukwa chake, zovuta zaukadaulo za ma bearing a mphamvu ya mphepo ndizokwera, ndipo makampaniwa amaziona ngati turbine ya mphepo yovuta. Chimodzi mwa zigawo zake.
Mphamvu ya mphepo ndi yopangira mphamvu yapadera, makamaka kuphatikiza: kunyamula kwa yaw, kunyamula kwa pitch, kunyamula kwa main shaft, kunyamula kwa gearbox, kunyamula kwa jenereta. Pakati pawo, mabenereta ndi zinthu zomwe zimagwiritsidwa ntchito padziko lonse lapansi zomwe zili ndi ukadaulo wokhwima.
Makampani opanga mphamvu zamagetsi m'dziko langa pano akuphatikizapo shaft ya matailosi, shaft ya Luo, zitsulo za Dalian, ukadaulo wofufuza za shaft, Tianma, ndi zina zotero, ndipo mphamvu yopangira ya mabizinesi omwe ali pamwambapa imayang'ana kwambiri ma bearing a yaw ndi ma bearing a pitch okhala ndi malire otsika aukadaulo.
Ponena za ma bearing ofunikira a spindle, makampani opanga ma bearing apakhomo amapanga ma grade 1.5 MW ndi 2.x MW, pomwe ma bearing okulirapo a spindle a MW grade amadalira kwambiri zinthu zochokera kunja.
Kuyambira chaka chatha, kufunikira kwa msika wa ma bearing amagetsi amphepo kwakhala kukukwera. Chifukwa cha mliri wapadziko lonse chaka chino, opanga ma bearing apakhomo alandila maoda ndipo alandira manja ofewa.
Tengani chitsanzo cha Waxshaft Group. Kuyambira Januwale mpaka Meyi 2020, ndalama zomwe zimapezedwa kuchokera ku bizinesi yayikulu ya bearing ya wind turbine zidakwera ndi 204% kuposa nthawi yomweyi chaka chatha.
Komabe, munthu wina wamkati mwa gulu la matailosi anati ma spindle bearing akhala akusowa chaka chino, makamaka ma spindle bearing a ma megawatts akuluakulu.
Pali lingaliro m'makampani kuti ma bearing akuluakulu mtsogolomu komanso ma bearing akuluakulu a megawatt adzachepetsa mphamvu yotumizira ya opanga ma turbine amphepo.
M'mbuyomu, pamsonkhano wapaintaneti wokhudza chitukuko cha mgwirizano wapadziko lonse lapansi cha makampani opanga magetsi amphepo akunyanja pansi pa mliriwu, Tian Qingjun, wachiwiri kwa purezidenti wamkulu wa Yuanjing Energy, adanenanso kuti opanga ochepa akunja monga Schaeffler ndi SKF ndi omwe angapange ma bearings akuluakulu, koma kutulutsa kwake konse chaka chino ndi pafupifupi ma seti 600, ndipo kudzagawidwa pamsika wapadziko lonse wamagetsi amphepo akunyanja.
Nthawi yomweyo, pambuyo pa kufalikira kwa mliri wa ku Ulaya, mafakitale a Schaeffler, SKF ndi mafakitale ena onyamula ma bearing ku Europe akhudzidwa kwambiri, makamaka ku Europe. Ogulitsa zinthu zopangira ena ndi ochokera ku Italy.
Tinganene kuti mphamvu yonyamula ma spindle yomwe ilipo pakadali pano siikwanira zosowa za makampani opanga magetsi amphepo.
Kupeza malo a ma main bearings? Ndi mwayi komanso ndi vuto
Munthu wina mumakampani opanga magetsi amphepo yemwe sanafune kutchulidwa dzina lake wavumbulutsa kuti pankhani ya kusowa kwa ma bearing akuluakulu amagetsi amphepo, opanga ma turbine amphepo pakadali pano akugwiritsa ntchito ma bearing akuluakulu apakhomo, makamaka ma shaft a matailosi ndi ma shaft a Luo.
Poyankha, mtolankhaniyo anafunsa Li Yi kuti atsimikizire. Iye anati pali opanga mainframe ena omwe amasankha ma bearings ochokera kunja chaka chonse ndipo ayamba kusintha m'malo mwa makampani ena.
Kupeza malo athunthu a ma bearing akuluakulu a mphamvu ya mphepo ndi njira yayitali. Anthu omwe ali mkati mwa matailosi omwe atchulidwa pamwambapa amakhulupirira kuti chinthu chachikulu chomwe chimalimbikitsa malo a masiku ano ndi kusowa kwa ma bearing akuluakulu.
Zikumveka kuti shaft ya Luo ndi shaft ya matailosi ndi zinthu zambiri, zokhala ndi luso pakupanga ma bearing a mphamvu ya mphepo, komanso zili ndi zaka zambiri zogwirira ntchito, kotero munthawi ino yokhazikika, kukhazikitsa kungakhale koyamba kutenga maoda a ma bearing akuluakulu a mphamvu ya mphepo.
Komabe, anthu omwe ali pamwambawa adanenabe kuti pali kusiyana pakati pa kupanga ma spindle bearing a m'dziko muno ndi mayiko akunja pankhani ya kapangidwe, kuyerekezera ndi kusonkhanitsa zokumana nazo pa ntchito.
Mtolankhaniyo adamva kuti opanga mainframe ena adzalowererapo pa opanga ma bearing kuchokera pa kafukufuku woyamba ndi chitukuko akasankha kusintha ma spindle bearing ndi malo. Nthawi yomweyo, adzatumiza oyang'anira kuti atsatire njirayi.
Malinga ndi Li Yi, njira yogwirira ntchito imeneyi inali yosowa kwambiri m'mbuyomu, ndipo inayamba pambuyo poti kubedwa kwa zinthu kwayamba.
Chifukwa pakadali pano, opanga ambiri opanga ma bearing amagetsi amphepo alemba ntchito akatswiri ndi akatswiri aukadaulo am'deralo ndi akunja, zomwe zalimbikitsa opanga ma bearing amagetsi amphepo ndi opanga ma bearing aluso am'deralo kuti akhale ndi kufotokozera kwakuya, koyandikira komanso kogwira mtima kwaukadaulo komanso kusinthana pakati pa gawo loyambirira la kafukufuku ndi chitukuko cha ma bearing amagetsi amphepo. Mgwirizanowu walimbitsa chidaliro cha mbali zonse ziwiri, ndipo nthawi yomweyo, kudzera mu kugawana ndi kufotokozera malingaliro opanga ndi malingaliro opanga, kapangidwe ka ma bearing amagetsi amphepo ndi injini zazikulu kakonzedwa bwino. Akukhulupirira kuti mgwirizano woterewu wowona mtima komanso wogwirizana udzathandiza makampani opanga magetsi amphepo kupita patsogolo limodzi.
Ponena za malo omwe ma bearing akuluakulu amagetsi amphepo amagwirira ntchito, anthu ambiri ogwira ntchito m'makampani amakhulupirira kuti uwu ndi lupanga lakuthwa konsekonse, lomwe ndi mwayi komanso vuto kwa ma bearing akuluakulu am'nyumba.
