Jenereta Set Ndiye Zida Zofunika Kwambiri pa Hydropower Station

Mphamvu ndizo maziko a chitukuko cha anthu ndi chithandizo ndi mphamvu za kukula kwachuma cha dziko.Mphamvu sizongogwirizana kwambiri ndi chitukuko cha anthu, komanso zimagwira ntchito yosasinthika pa chitukuko cha anthu ndi zachuma.Masiku ano ku China kagwiritsidwe ntchito ka Mphamvu zamagetsi, mphamvu zotsalira zakale zikadalipobe, ndipo kutsutsana pakati pa mphamvu zochepa ndi kufunikira kowonjezereka kukukulirakulira, zomwe zakhala zolepheretsa chitukuko cha anthu ndi zachuma.Munthawi imeneyi, ngati mphamvu zongowonjezwdwa, mphamvu ya hydropower idalowa m'mbiri yakale ndipo idatenga malo ofunikira.Kugwiritsidwa ntchito kwa mphamvu padziko lonse lapansi kukuyembekezeka kuwonjezereka nthawi 1.5 kuchokera ku matani 1174.3 biliyoni mu 2010 kufika matani 175.17 biliyoni mu 2035. Kugwiritsidwa ntchito kwa mafuta opangira mafuta tsopano kuli pafupifupi 90 peresenti.Kusintha kwazinthu zachilengedwe ndi mphamvu zoyera ziyenera kufufuzidwanso chifukwa cha mafuta osasinthika komanso momwe chilengedwe chimakhudzira thanzi lawo.Mphamvu ya Hydropower imapanga 15% ya magetsi padziko lonse lapansi ndipo ndi gwero lalikulu la mphamvu zongowonjezedwanso komanso zokhazikika.

The turbine ndiye mtima wa hydropower station iliyonse, kutembenuza mphamvu yomwe ingakhale yamadzi kukhala mphamvu yamakina.Seti ya jenereta ya hydro ndi zida zofunika kwambiri pa siteshoni yopangira magetsi amadzi, ndipo kugwira ntchito kwake kotetezeka ndi chitsimikizo chofunikira kuwonetsetsa kuti magetsi amagetsi achitetezo, apamwamba kwambiri komanso azachuma komanso kuperekedwa kwa magetsi pamalo opangira magetsi.Zimagwirizana mwachindunji ndi ntchito yotetezeka komanso yokhazikika ya gridi yamagetsi, ndipo imatsimikizira ubwino wachuma ndi chikhalidwe cha malo opangira magetsi.Zotsatira zikuwonetsa kuti kukhazikika kwa hydraulic komwe kumachitika chifukwa cha chipwirikiti kugunda kwa turbine ndikofunikira kwambiri kuti mudziwe kukhazikika kwa turbine.M'malo mwake, pakugwirira ntchito kwa mayunitsi a hydropower, kugwedezeka nthawi zambiri kumachitika chifukwa cha makina ndi magetsi kuphatikiza kugwedezeka komwe kumachitika chifukwa cha kusakhazikika kwa hydraulic.Malinga ndi ziwerengero, pafupifupi 80% ya kulephera kapena ngozi za mayunitsi amagetsi amadzi zimawonetsedwa ndi ma siginecha akugwedezeka.Chifukwa chake, ndikofunikira kwambiri kuphunzira njira yowunikira zolakwika za hydropower unit ndikuzindikira mwanzeru kugwedezeka kwa mphamvu yamagetsi a hydropower pakuwongolera kuchuluka kwa matenda amagetsi amagetsi ku China ndikuchepetsa kusiyana ndiukadaulo wofananira kunja.

Pakuchulukirachulukira kwa mphamvu ndi kukula kwa gawo la hydro-jenereta, kukhazikika kwa magwiridwe antchito kwakhala vuto lasayansi ndi uinjiniya lomwe likuyenera kuwerengedwa.Kuwunika mozama kachitidwe ka kugwedezeka kwa gawo la hydro-jenereta kumatha kutsimikizira kudalirika kwake ndikuyendetsa bwino ndikupewa kapena kuchepetsa kuvulaza komwe kungabwere chifukwa cha kulephera kwa kugwedezeka kwa unit.Ndikofunikira kwambiri kumvetsetsa kugwedezeka kwa hydraulic turbine.

Zomwe zimayambitsa kugwedezeka kwamakina ndi:

Kuyanjanitsa kosayenera kwa shaft yayikulu pa flange, kumasula kugwirizana kapena kumasula magawo okonzekera kumabweretsa kugwedezeka kwa mzere waukulu wosweka;

Kugwedezeka kwa gawo lozungulira la gawo chifukwa cha kusalinganika kwakukulu, kupindika kapena kugwa kwa magawo;

Kugwedezeka chifukwa cha mikangano pakati pa gawo lozungulira ndi gawo lokhazikika la unit, kusiyana kwakukulu pakati pa chitsamba cholondolera, chitsamba chosakanikirana, kugwedezeka kwamutu ndi zina zotero.

Kugwedezeka komwe kumachitika chifukwa cha kuwonongeka kwa makina kapena zolakwika kumakhala ndi mawonekedwe ofanana.Kuthamanga kwafupipafupi ndi kutembenuka kwafupipafupi kapena kutembenuka kangapo, ndipo mphamvu yosagwirizana ndi yozungulira kapena yopingasa.

Kugwedezeka kwamagetsi kumatha kugawidwa m'mitundu iwiri: kugwedezeka kwafupipafupi komanso kugwedezeka kwapolar.Zomwe zimachititsa ma elekitiromu kutembenuka kwafupipafupi ndizofupikitsa zozungulira zozungulira, kusiyana kwa mpweya wa rotor yosasunthika, kugwira ntchito kwa asymmetric ndi dongosolo lolakwika la mitengo ya maginito, zomwe zimapangitsa maginito asymmetry, kusagwirizana kwa maginito ndi kugwedezeka.Kutsitsa koyambira kwa Stator kumayambitsa kugwedezeka kwakukulu kwa 100Hz.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yomwe idakhazikitsidwa mu 2006, ndiyopanga jenereta ya dizilo ku China, yomwe imaphatikiza kupanga, kupereka, kutumiza ndi kukonza ma jenereta a dizilo.Zogulitsa zimaphatikizapo Cummins, Perkins, Volvo , Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. ndi mphamvu osiyanasiyana 20kw-3000kw, ndi kukhala fakitale awo OEM ndi pakati luso.
