Zigawo mu Wind Turbine Nacelle
Ma turbine a mphepo ndi amodzi mwa njira zatsopano kwambiri zomwe zimagwiritsidwa ntchito popanga mphamvu yoyera. Makinawa amagwiritsa ntchito mphamvu ya mphepo kusandutsa masamba a turbine, omwe kenako amasintha mphamvu ya kinetic kukhala mphamvu yamagetsi. Chimodzi mwa zinthu zofunika kwambiri pa turbine ya mphepo ndi nacelle—chikwama chomwe chimateteza zigawo zamakina ndi zamagetsi zomwe zimasintha mphamvu ya mphepo kukhala magetsi.
Kumvetsetsa Nacelle
Nacelle ya turbine ya mphepo ndi kapangidwe kooneka ngati kapisozi komwe kali pamwamba pa nsanja ndikuthandizira masamba a turbine. Nacelle imagwira ntchito yofunika kwambiri poteteza ndikuthandizira zinthu zingapo zofunika zomwe zimayambitsa kusintha kwa mphamvu. Ngakhale zingawoneke zosavuta kuchokera kunja, mkati mwa nacelle muli zida ndi machitidwe osiyanasiyana ovuta. M'nkhaniyi, tikambirana za zigawo zazikulu za nacelle ya turbine ya mphepo.
1. Rotor ndi Main Shaft
Chozungulira ndi gawo la turbine ya mphepo yomwe imakhala ndi masamba a turbine. Masamba awa ndi gawo lodziwika bwino la turbine ya mphepo, ndipo amazungulira akakumana ndi mphepo.
– Ma Turbine Blades: Kawirikawiri amapangidwa ndi zinthu zopangidwa ndi zinthu zosiyanasiyana monga fiberglass kapena carbon fiber. Amapangidwa ndi aerodynamically kuti azitha kugwira mphamvu ya mphepo kwambiri.
– Shaft Yaikulu: Rotor imalumikizidwa ku shaft yayikulu, yomwe ndi shaft yolimba, yozungulira yomwe imatumiza mphamvu yamakina kuchokera ku masamba a rotor kupita ku jenereta. Shaft yayikulu nthawi zambiri imalumikiza rotor ku makina osinthira magiya.
2. Dongosolo la Gearbox
Bokosi la giya ndi chinthu chofunikira kwambiri chomwe chimawonjezera liwiro lozungulira la masamba a turbine. Masamba a turbine nthawi zambiri amazungulira pa liwiro lotsika, pakati pa 10 ndi 20 revolutions pa mphindi (RPM), koma majenereta amafunika liwiro lalikulu kuti apange magetsi moyenera, nthawi zambiri pafupifupi 1.000 mpaka 1.500 RPM.
– Ntchito: Bokosi la giya limawonjezera liwiro lozungulira kudzera mu magiya angapo omwe amafulumizitsa kuzungulira kwa shaft yayikulu isanaperekedwe ku jenereta.
– Mitundu ya Gearbox: Pali mitundu ingapo ya ma gearbox, kuphatikizapo ma gearbox a planetary, helical, ndi worm, iliyonse ili ndi ubwino ndi kuipa kwake kutengera kapangidwe ka turbine ndi zofunikira za mphamvu.
3. Jenereta
Jenereta ndi chinthu chomwe chimasintha mphamvu yamakina kuchokera ku shaft yayikulu kukhala mphamvu yamagetsi. Pali mitundu ingapo ya majenereta omwe amagwiritsidwa ntchito mu ma turbine amphepo:
– Jenereta Yoyambitsa: Nthawi zambiri imagwiritsidwa ntchito chifukwa cha mtengo wake wotsika komanso kulimba kwake.
– Jenereta Yogwirizana: Imatha kupereka kukhazikika kwa ma frequency abwino komanso magwiridwe antchito apamwamba poyerekeza ndi jenereta yopangira zinthu.
– Chopangira Magnet Chokhazikika: Chimagwira ntchito bwino kwambiri komanso chimakhala ndi ndalama zochepa zokonzera koma chimakhala chokwera mtengo kwambiri popanga poyamba.
4. Dongosolo Loyendetsera Mabuleki
Dongosolo la mabuleki mu turbine ya mphepo limathandiza kuletsa rotor kuti isazungulire ngati pali mphepo yambiri kapena ngati pakufunika kukonza.
– Kuyendetsa Mabuleki a Aerodynamic: Izi zimaphatikizapo kuzungulira masamba a turbine kuti muchepetse liwiro lozungulira.
– Kukonza Mabuleki Mwamakina: Kugwiritsa ntchito ma disc ndi ma pad a mabuleki kuti muchepetse kapena kuyimitsa rotor.
5. Njira Yoziziritsira
Majenereta ndi ma gearbox amapanga kutentha kwambiri akamagwira ntchito, kotero makina oziziritsira ndi ofunikira kuti zinthu zamakina zigwire ntchito bwino komanso kuti zisawonongeke chifukwa cha kutentha kwambiri.
– Mpweya Woziziritsa: Ma turbine ambiri amphepo amagwiritsa ntchito njira zoziziritsira pogwiritsa ntchito mpweya chifukwa ndi osavuta komanso otsika mtengo.
– Choziziritsira Madzi: Chimagwiritsidwa ntchito m'ma turbine akuluakulu kapena m'malo ovuta kwambiri. Dongosololi limagwiritsa ntchito madzi apadera monga mafuta kapena madzi/glycol kuziziritsa zigawo zake.
6. Njira Yopaka Mafuta
Kupaka mafuta ndikofunikira pochepetsa kukangana kwa zinthu zosiyanasiyana monga ma gearbox ndi ma bearing. Izi zimapangitsa kuti ntchito igwire bwino ntchito komanso zimawonjezera nthawi ya moyo wa zinthuzo.
– Makina Odzipangira Okha: Ma turbine ambiri amakono amphepo ali ndi makina odzola okha omwe amawongolera ndikuyang'anira mafuta nthawi zonse.
– Pamanja: Mu machitidwe ena osavuta kapena akale, mafuta odzola amachitidwa pamanja ndipo amafunika kuyang'aniridwa nthawi zonse.
7. Machitidwe Owongolera ndi Kuwunikira Pakompyuta
Kuti ma turbine amphepo azigwira ntchito bwino komanso mosamala, njira zamagetsi zowongolera ndi kuyang'anira ndizofunikira.
– Kulamulira kwa PLC: Pulogalamu Yowongolera Logic (PLC) imagwiritsidwa ntchito kuwongolera ndikuwunika mbali zosiyanasiyana za ntchito ya turbine, monga liwiro la mphepo, malo a tsamba, ndi momwe jenereta ilili.
– SCADA: Machitidwe a Supervisory Control and Data Acquisition (SCADA) amathandiza kuyang'anira ndi kuwongolera ma turbine amphepo patali. Kudzera mu masensa ndi mapulogalamu, ogwiritsa ntchito amatha kuyang'anira momwe turbine imagwirira ntchito ndikupeza mavuto msanga.
- Masensa: Masensa osiyanasiyana amagwiritsidwa ntchito kuzindikira liwiro la mphepo, kutentha, kugwedezeka, ndi malo a tsamba la turbine.
8. Dongosolo la Yaw
Dongosolo la yaw limagwiritsidwa ntchito kusintha njira ya nacelle kuti masamba a turbine aziyang'anana ndi mphepo nthawi zonse kuti mphamvu zigwire bwino ntchito.
– Yaw Motor: Imayendetsa nacelle kuti izungulire molingana ndi momwe mphepo imayendera.
– Sensor ya Mphepo: Imazindikira komwe mphepo ikupita komanso liwiro lake kuti iwonetse injini ya yaw kuti isinthe malo a nacelle.
9. Transmission ndi Transformer
Ma turbine a mphepo nthawi zambiri amalumikizidwa ku netiweki yotumizira mphamvu yomwe imafuna ma voltage ambiri. Chifukwa chake, transformer yomwe ili mkati kapena pafupi ndi nacelle imagwiritsidwa ntchito kuwonjezera magetsi opangidwa ndi jenereta.
– Transformer: Imasintha magetsi kuchokera ku jenereta kupita ku magetsi ambiri kuti ipereke magetsi.
– Zingwe ndi Zida Zosinthira: Zingwe zamagetsi zomwe zimalumikiza jenereta ku transformer kenako n’kupita ku gridi kapena netiweki yogawa magetsi yapafupi.
10. Nyumba ndi Kapangidwe kake
Nacelle iyenera kukhala yolimba mokwanira kuti ipirire katundu wamakina komanso nyengo yoipa kwambiri. Chifukwa chake, nyumba ya nacelle imapangidwa ndi zipangizo zolimba komanso zolimba.
– Zipangizo: Kawirikawiri zimapangidwa ndi chitsulo kapena zinthu zolimba koma zopepuka.
– Kapangidwe ka Aerodynamic: Amachepetsa kukana mphepo ndikuwonjezera kukhazikika kwa turbine yonse.
Mapeto
Nacelle ya turbine ya mphepo imakhala ndi zinthu zingapo zofunika zomwe zimagwirira ntchito limodzi kuti zisinthe mphamvu ya mphepo kukhala magetsi ogwiritsidwa ntchito. Kuyambira rotor ndi gearbox mpaka makina owongolera ndi kuziziritsa amagetsi, gawo lililonse limagwira ntchito yofunika kwambiri pakuwonetsetsa kuti turbine ya mphepo ikugwira ntchito bwino komanso modalirika kwambiri. Kumvetsetsa zinthuzi kumatithandiza kuyamikira zovuta komanso zodabwitsa zaukadaulo zomwe zimatithandiza kugwiritsa ntchito mphamvu ya mphepo ngati gwero lamphamvu loyera komanso lobwezeretsedwanso.
