Ukusetshenziswa kwe-glass fiber ku-wind turbine blade

Imboni yamandla omoya ikakhulukazi yakhiwe ukukhiqizwa kwezinto ezingavuthiwe ezikhuphuka nomfula, ukukhiqizwa kwezingxenye ezimaphakathi nomfula kanye nokukhiqizwa kwenjini yomoya, kanye nokusebenza kwepulazi lomoya eliphansi nomfula kanye nokusebenza kwegridi yamandla.I- Wind turbine yakhiwa ikakhulukazi i-impeller, igumbi lenjini nombhoshongo.Njengoba umbhoshongo ngokuvamile ungaphansi kokunikezwa amabhidi ahlukene ngesikhathi sokubhida kwepulazi lomoya, i-wind turbine isho impeller negumbi lenjini ngalesi sikhathi.I-impeller ye-fan inesibopho sokuguqula amandla omoya abe amandla emishini.Yakhiwe ngama-blades, ihabhu kanye ne-fairing.Ama-blades aguqula amandla e-kinetic omoya abe amandla omshini wama-blades kanye ne-main shaft, bese abe amandla kagesi ngokusebenzisa ijeneretha.Usayizi nokuma kwe-blade kunquma ngokuqondile ukusebenza kahle kokuguqulwa kwamandla, kanye namandla eyunithi nokusebenza.Ngakho-ke, i-wind turbine blade isendaweni eyinhloko ekwakhiweni kwe-wind turbine.

Izindleko zama-blade amandla omoya zibalelwa ku-20% - 30% wesamba sezindleko zalo lonke uhlelo lokuphehla amandla omoya.Izindleko zokwakha ipulazi lomoya zingahlukaniswa ngezindleko zemishini, izindleko zokufaka, ubunjiniyela bokwakha nezinye izindleko.Uma sithatha ipulazi lomoya elingu-50MW njengesibonelo, cishe u-70% wezindleko uvela ezindlekweni zemishini;U-94% wezindleko zemishini uvela ezintweni zokuphehla ugesi;U-80% wezindleko zemishini yokuphehla ugesi uvela ezindlekweni zeturbine yomoya kanye no-17% ezindlekweni zombhoshongo.

Ngokwalokhu kubala, izindleko zenjini yomoya zibalelwa ku-51% wesamba sokutshalwa kwezimali kwesiteshi sikagesi, futhi izindleko zombhoshongo zibalelwa ku-11% wesamba semali etshaliwe.Izindleko zokuthenga kokubili yizindleko eziyinhloko zokwakha ipulazi lomoya.Ama-wind power blades azoba nezici zobukhulu obukhulu, ukuma okuyinkimbinkimbi, izidingo zokunemba okuphezulu, ukusatshalaliswa kobuningi obufanayo kanye nokumelana nesimo sezulu esihle.Njengamanje, isilinganiso semakethe yonyaka samandla omoya singama-yuan ayizigidi eziyizinkulungwane eziyi-15-20.

Njengamanje, u-80% wezindleko ze-blade uvela ezintweni ezingavuthiwe, lapho inani eliphelele le-reinforcing fiber, i-core material, i-matrix resin ne-adhesive lidlula ama-85% yenani lenani eliphelele, ingxenye ye-reinforcing fiber kanye ne-matrix resin idlula ama-60% , futhi ingxenye ye-adhesive ne-core material idlula u-10%.I-Matrix resin "ukufakwa" kwayo yonke i-blade, egoqa i-fiber material kanye ne-core material.Inani lezinto ezigoqiwe empeleni linquma inani lempahla ye-matrix, okungukuthi, i-fiber material.

Ngokukhula kwesidingo semakethe sokusebenzisa kahle ama-wind power blades, ukuthuthukiswa kwama-wind power blades kuya ngezinga elikhulu sekuphenduke inkambiso engenakugwemeka.Ngaphansi kobude obufanayo bama-blades, isisindo sezindwani ezisebenzisa i-glass fiber njengesiqiniseko sikhulu kakhulu kunaleso sisebenzisa i-carbon fiber njengesiqiniseko, esithinta ukusebenza nokusebenza kahle kokuguqulwa kwama-wind turbines.
