Elangeni elikhipha umkhovu etsheni, kwahlokoma imishini yendawo ekhiqiza amandla omoya yefektri eyaziwayo yasekhaya, futhi isikole sasimatasa. Abasebenzi ababelapho bebephuthuma ukwenza ama-oda okuqinisekisa isidingo sabakhiqizi bezinjini zomoya basekhaya nabangaphandle.
Kodwa-ke, ngesikhathi esifanayo ukuthi amandla omoya "ukufakwa kwe-rush" kuye kwaletha ukwanda okusheshayo kwesidingo esithwalayo, ubhubhane luye lwathinta ukukhiqizwa okuvamile kwabakhiqizi abakhiqizayo ekhaya nakwamanye amazwe. Amabhodi amakhulu wamandla omoya abelokhu eshoda.
U-Luo Yi, oyilungu langaphakathi le-Luo Shao (igama-mbumbulu lapha ngesicelo somxoxi) utshele izintatheli ukuthi, empeleni, ama-oda ama-spindle ama-spindle bearings akhule kakhulu kusukela engxenyeni yesibili yonyaka odlule, kanti amanye anamandla amakhulu. ama-spindles okwamanje athintwa yilolu bhubhane. Ama-Bearings nawo adluliselwe kubakhiqizi abazalayo basekhaya ukuze baqale ucwaningo nokuthuthukiswa kanye nokuhlinzekwa kwenqwaba encane.
Ngaphansi kwengcindezi ephindwe kabili yokufakwa kwejubane kanye nesimo esiwubhubhane, abakhiqizi bamandla omoya basekhaya babhekene nezinselelo ezinkulu...
Ama-oda efekthri yasekhaya anyukile
Ama-wind power bearings angenye yezinto ezibalulekile ezisekela izinjini zomoya. Akumele nje kuphela bathwale imithwalo emikhulu, kodwa futhi babe neminyaka yokuphila okungenani engu-20 njengenjini enkulu. Ngakho-ke, inkimbinkimbi yobuchwepheshe yamabheringi wamandla omoya iphezulu, futhi ibonwa imboni njengenjini yomoya enzima yendawo. Enye yezingxenye.
Ukuthwala amandla omoya kuwukuthwala okukhethekile, ikakhulukazi okuhlanganisa: i-yaw bear, i-pitch bear, i-main shaft bear, i-gearbox bear, i-generator bear. Phakathi kwazo, ama-generator bearings ngokuyisisekelo yimikhiqizo yendawo yonke enobuchwepheshe obuvuthiwe.
Izinkampani zamanje zezwe lami ezithwala amandla omoya ikakhulukazi zifaka i-tile shaft, i-Luo shaft, i-Dalian metallurgy, ubuchwepheshe bocwaningo lwe-shaft, i-Tianma, njll., futhi amandla okukhiqiza amabhizinisi angenhla agxile kakhulu kuma-yaw bearings nama-pitch bearings anemibundu yobuchwepheshe ephansi.
Ngokuqondene namabhodi okuphotha abalulekile, izinkampani ezikhiqizayo ezifuywayo ikakhulukazi zenza amamaki angu-1.5 MW kanye no-2.x MW, kuyilapho amabheringi amakhulu ebanga le-MW athembele kakhulu ekuthengeni kwamanye amazwe.
Kusukela ngonyaka odlule, isidingo semakethe samabheringi omoya siyakhula. Bethintwe ubhubhane lomhlaba wonke kulo nyaka, abakhiqizi bemikhiqizo yasekhaya bathole ama-oda futhi bathola izandla ezithambile.
Thatha i-Waxshaft Group njengesibonelo. Kusukela ngoJanuwari kuya kuMeyi 2020, imali engenayo evela ebhizinisini elikhulu le-wind turbine bearing inyuke ngo-204% esikhathini esifanayo ngonyaka odlule.
Kodwa-ke, umuntu ongaphakathi eqenjini le-tile shaft uthe ama-spindle bearings abeshoda kulo nyaka, ikakhulukazi ama-spindle bearings ama-megawatts amakhulu.
Kunombono embonini wokuthi ama-bearings amakhulu esikhathini esizayo ngisho nama-megawatt ama-bearings amakhulu azokhawulela umthamo wokuthutha wabakhiqizi bezinjini zomoya.
Phambilini, engqungqutheleni eku-inthanethi yokuthuthukiswa ngokubambisana komhlaba wonke kochungechunge lwemboni yamandla omoya olwandle ngaphansi kwalolu bhubhane, u-Tian Qingjun, iphini likamongameli omkhulu we-Yuanjing Energy, waveza ukuthi bambalwa kuphela abakhiqizi bangaphandle abafana no-Schaeffler kanye ne-SKF abangakhiqiza i-ingawa enkulu. ama-bearings, kodwa Isamba sawo esiphuma kulo nyaka singamasethi angama-600, futhi sizosatshalaliswa emakethe yamandla omoya asogwini lomhlaba jikelele.
Ngesikhathi esifanayo, ngemva kokugqashuka kobhubhane lwaseYurophu, i-Schaeffler, i-SKF nezinye izimboni ezithwala impahla eYurophu ziye zathinteka kakhulu, ikakhulukazi eYurophu. Abanye abahlinzeki bempahla eluhlaza bavela e-Italy.
Kungashiwo ukuthi umthamo wamanje wokuthwala ukuphotha ukude nokuhlangabezana nezidingo zemboni yamandla omoya.
Ukwenziwa kwasendaweni kwamabheringi amakhulu? Kuyithuba kodwa futhi kuyinselelo
Umuntu osembonini yamandla omoya ongathandanga kudalulwe igama lakhe uveze ukuthi esimweni sokushoda kwama-main main bearings aphehla amandla omoya, abakhiqizi bezinjini zomoya njengamanje basebenzisa ama-bearing main asekhaya, ikakhulukazi ama-tile shafts nama-Luo shafts.
Ephendula, intatheli ibuze uLi Yi ukuthi aqinisekise. Uthe ngempela kukhona abakhiqizi abakhulu abakhetha ama-bearings avela kwamanye amazwe unyaka wonke futhi asebeqalile ukushintsha ngaphakathi.
Ukwenziwa kwasendaweni okuphelele kwamabheringi amakhulu omoya kuyinqubo ende. Abangaphakathi bama-tile shafts okukhulunywe ngawo ngenhla bakholelwa ukuthi isici esiyinhloko esikhuthaza ukwenziwa kwasendaweni namuhla ukushoda kwama-bearings ayinhloko.
Kuyaqondakala ukuthi i-Luo shaft kanye ne-tile shaft iwuhlu oluphelele lwempahla, enolwazi ekuthuthukisweni kwama-spindle power bearings, futhi futhi ineminyaka eminingi yokusebenza okufakiwe, ngakho-ke kulo mzuliswano wokufakwa kwe-rush kungaba ngowokuqala ukuthatha. ama-oda ama-bearings ayinhloko wamandla omoya.
Noma kunjalo, laba bangaphakathi abangenhla basasho ukuthi lisekhona igebe phakathi kokukhiqizwa kwasekhaya okuphothayo kanye namazwe angaphandle mayelana nokuklama, ukulingisa kanye nokunqwabelana kwesipiliyoni sokusebenza.
Intatheli ifunde ukuthi abanye abakhiqizi be-mainframe bazongenela kubakhiqizi abathwele kusukela ocwaningweni lokuqala nasekuthuthukisweni lapho bekhetha ukufaka esikhundleni samabheringi okuphotha ngendawo. Ngesikhathi esifanayo, bazothumela abaphathi ukuthi balandelele inqubo.
NgokukaLi Yi, le ndlela yokubambisana yayingavamile esikhathini esidlule, futhi yabonakala ngemva kokuqala komjikelezo wamanje wokuphanga.
Ngoba njengamanje, abakhiqizi abaningi abasingatha amandla omoya baqashe izisebenzi zasekhaya nezangaphandle ezithwala izisebenzi nezichwepheshile, okuye kwakhuthaza abakhiqizi bamandla omoya kanye nabakhiqizi abakhiqiza amandla omoya basekhaya ukuba babe nencazelo ejulile, eseduze futhi ephumelelayo yezobuchwepheshe kanye nokushintshanisa ekuqaleni. wamandla omoya ane-R&D Ukubambisana kuqinise ukwethembana kwezinhlangothi zombili, futhi ngesikhathi esifanayo, ngokwabelana nokubhekisela kwemibono yokuklama kanye nemibono yokuklama, ukwakheka kwamabheringi omoya kanye nezinjini ezinkulu kwenziwe ngcono kangcono. Ukholelwa ukuthi lolu hlobo lokubambisana okuqotho nokubambisana luzosiza imboni yamandla omoya ukuba ithuthuke ngokubambisana.
Ukuze kwenziwe kwasendaweni ama-bearings ayinhloko wamandla omoya, abaningi abangaphakathi embonini bakholelwa ukuthi lena inkemba esika nhlangothi zombili, okuyithuba kanye nenselelo yama-bearings asekhaya.
