Elangeni elishisayo, imishini yendawo yokukhiqiza ama-air power bearing efektri eyaziwayo yasekhaya yaduma, futhi isikole sasimatasa. Izisebenzi ezazilapho zaziphuthuma ukwenza ama-oda ukuqinisekisa isidingo sabakhiqizi bama-wind turbine basekhaya nabangaphandle.
Kodwa-ke, ngesikhathi esifanayo lapho "ukufakwa kwe-rush" kwamandla omoya kulethe ukwanda okusheshayo kwesidingo sama-bearing, ubhubhane luthinte ukukhiqizwa okuvamile kwabakhiqizi bama-bearing ekhaya nakwamanye amazwe. Ama-bearing amakhulu amandla omoya abelokhu entuleka.
ULuo Yi, ilungu labasebenzi bangaphakathi beLuo Shao (igama elingelona elangempela lapha ngesicelo somuntu oxoxisana naye) utshele izintatheli ukuthi, empeleni, ama-oda ama-spindle bearings anamandla omoya akhuphuke kakhulu kusukela engxenyeni yesibili yonyaka odlule, futhi amanye ama-spindle anamandla aphezulu okwamanje athintwe yilolu bhubhane. Ama-bearings nawo adluliselwe kubakhiqizi basekhaya bearings ukuze baqale ucwaningo nentuthuko kanye nokuhlinzekwa okuncane.
Ngaphansi kwengcindezi ephindwe kabili yokufakwa kwejubane kanye nesimo sobhubhane, abakhiqizi bamandla omoya basekhaya babhekene nezinselele ezinkulu...
Ama-oda efektri yokuthwala amabhere asekhaya akhuphuke kakhulu
Ama-wind power bearings angenye yemishini ebalulekile yokusekela ama-wind turbines. Akufanele nje kuphela athwale imithwalo emikhulu yokushayisana, kodwa futhi abe nokuphila okungenani iminyaka engama-20 njengenjini eyinhloko. Ngakho-ke, ubunzima bobuchwepheshe bama-wind power bearings buphakeme, futhi kubhekwa yimboni njenge-wind turbine enzima yendawo. Enye yezingxenye.
Ukuthwala amandla omoya kuyibhereyi ekhethekile, ikakhulukazi ehlanganisa: ukuthwala kwe-yaw, ukuthwala kwephimbo, ukuthwala komgodi oyinhloko, ukuthwala kwegiya, ukuthwala kwejenereyitha. Phakathi kwazo, amabhereyitha ejenereyitha empeleni ayimikhiqizo ebanzi enobuchwepheshe obuvuthiwe.
Izinkampani zamanje zezwe lami ezithwala amandla omoya zifaka kakhulu 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 anemingcele yobuchwepheshe ephansi kakhulu.
Ngokuphathelene nama-key spindle bearings, izinkampani zama-bearings zasekhaya zikhiqiza kakhulu ama-1.5 MW kanye nama-2.x MW grades, kuyilapho ama-spindle bearings amakhulu e-MW grade bearings ethembele kakhulu ekungenisweni kwamanye amazwe.
Kusukela ngonyaka odlule, isidingo semakethe sama-bearings kagesi omoya besilokhu sikhula. Bethintwe ubhubhane womhlaba wonke kulo nyaka, abakhiqizi bama-bearings basekhaya bathole ama-oda futhi bathole izandla ezithambile.
Thatha i-Waxshaft Group njengesibonelo. Kusukela ngoJanuwari kuya kuMeyi 2020, imali engenayo evela ebhizinisini eliyinhloko le-wind turbine bearing ikhuphuke ngo-204% esikhathini esifanayo ngonyaka odlule.
Kodwa-ke, umuntu ongaphakathi eqenjini le-tile shaft uthe ama-spindle bearing abe entuleka kulo nyaka, ikakhulukazi ama-spindle bearing ama-megawatt amakhulu.
Kukhona umbono embonini wokuthi ama-bearings amakhulu esikhathini esizayo ngisho nama-bearings amakhulu e-megawatt azonciphisa amandla okuthumela kwabakhiqizi be-wind turbine.
Ngaphambilini, engqungqutheleni eku-inthanethi mayelana nokuthuthukiswa kokubambisana komhlaba wonke kweketanga lemboni yamandla omoya asogwini ngaphansi kwalesi sifo, uTian Qingjun, iphini likamongameli omkhulu weYuanjing Energy, ukhombe ukuthi abakhiqizi abambalwa bangaphandle abanjengoSchaeffler ne-SKF bangakhiqiza ama-main bearings amakhulu, kodwa umkhiqizo wawo wonke kulo nyaka ungamasethi angaba ngu-600, futhi uzosatshalaliswa emakethe yamandla omoya asogwini lomhlaba wonke.
Ngesikhathi esifanayo, ngemva kokuqubuka kobhubhane lwaseYurophu, i-Schaeffler, i-SKF kanye nezinye izimboni zokuthwala izinsimbi eYurophu ziye zathinteka kakhulu, ikakhulukazi eYurophu. Abanye abahlinzeki bezinto zokusetshenziswa bavela e-Italy.
Kungashiwo ukuthi amandla okuthwala i-spindle amanje awakwazi ukuhlangabezana nezidingo zemboni yamandla omoya.
Ukutholakala kwendawo yama-main bearings? Kuyithuba kodwa futhi kuyinselele
Umuntu osembonini yamandla omoya ongathandanga ukudalulwa igama lakhe uveze ukuthi uma kwenzeka ukushoda kwama-main bearings anamandla omoya, abakhiqizi be-wind turbine okwamanje basebenzisa ama-main bearings asekhaya, ikakhulukazi ama-tile shafts kanye nama-Luo shafts.
Iphendula, intatheli icele uLi Yi ukuthi aqinisekise. Uthe ngempela kukhona abakhiqizi be-mainframe abakhetha ama-bearings angenisiwe unyaka wonke futhi sebeqalile ukufaka esikhundleni sawo ngaphakathi ezweni.
Ukufakwa endaweni ephelele kwama-main bearings anamandla omoya kuyinqubo ende. Abantu abangaphakathi kwe-tile shafts okukhulunywe ngabo ngenhla bakholelwa ukuthi isici esiyinhloko esikhuthaza ukwenziwa kwendawo namuhla ukuntuleka kwama-main bearings.
Kuyaqondakala ukuthi i-shaft ye-Luo kanye ne-shaft yethayela ziwuhlu oluphelele lwezinto ezidingekayo, zinolwazi ekuthuthukisweni kwama-spindle bearings e-wind power, futhi zineminyaka eminingi yokusebenza okufakiwe, ngakho-ke kulo mjikelezo wokufakwa kwe-rush kungaba ngowokuqala ukuthatha ama-oda ama-bearings amakhulu e-wind power.
Noma kunjalo, abantu abangaphakathi abangenhla basasho ukuthi kusenegebe phakathi kokukhiqizwa kwe-spindle bearing yasekhaya kanye namazwe angaphandle maqondana nokuklama, ukulingisa kanye nokuqongelela ulwazi lokusebenza.
Intatheli ithole ukuthi abanye abakhiqizi be-mainframe bazongenela abakhiqizi be-bearing kusukela ocwaningweni nasekuthuthukisweni kokuqala lapho bekhetha ukufaka esikhundleni se-spindle bearing endaweni. Ngesikhathi esifanayo, bazothumela abaphathi ukuzolandela inqubo.
Ngokusho kukaLi Yi, le ndlela yokubambisana yayingavamile esikhathini esidlule, futhi yavela ngemva kokuqala komjikelezo wamanje wokuphanga.
Ngoba njengamanje, abakhiqizi abaningi be-air power host baqashe abasebenzi abangochwepheshe nabachwepheshe be-bearing basekhaya nabangaphandle, okuye kwakhuthaza abakhiqizi be-air power host kanye nabakhiqizi be-air professional bearing basekhaya ukuba babe nencazelo yobuchwepheshe ejulile, esondelene futhi ephumelelayo kanye nokushintshana esigabeni sokuqala se-R&D ye-wind power bearing. Ukubambisana kuqinise ukwethenjwa kwamaqembu womabili, futhi ngesikhathi esifanayo, ngokwabelana nokubhekisela kwemibono yokuklama kanye nemibono yokuklama, isakhiwo se-wind power bearing kanye nezinjini eziyinhloko sithuthukiswe kangcono. Ukholelwa ukuthi lolu hlobo lokubambisana okuqotho nokubambisana luzosiza imboni yamandla omoya ukuthi ithuthuke ndawonye.
Ukuze kutholakale indawo yama-main bearings anamandla omoya, abantu abaningi abangaphakathi embonini bakholelwa ukuthi lokhu kuyinkemba esika nhlangothi zombili, okuyithuba kanye nenselele yama-main bearings asekhaya.
