Malinga ndi "malamulo opangira ma hydraulic turbine model" aku China, mtundu wa hydraulic turbine uli ndi magawo atatu, ndipo gawo lililonse limasiyanitsidwa ndi mzere wawung'ono wopingasa "-". Gawo loyamba limapangidwa ndi zilembo za Chitchaina Pinyin ndi manambala achiarabu, momwe zilembo za Pinyin zimayimira madzi. Kwa mtundu wa turbine, manambala achiarabu akuwonetsa wothamanga, chitsanzo cha wothamanga yemwe akulowa mu mbiri yake ndi mtengo wake wa liwiro, chitsanzo cha wothamanga wosalowa mu mbiri ndi chiwerengero cha unit iliyonse, ndipo chitsanzo chakale ndi chiwerengero cha wothamanga; Pamagetsi osinthika, onjezani "n" pambuyo pa mtundu wa turbine. Gawo lachiwiri limapangidwa ndi zilembo ziwiri za Chitchaina za Pinyin, zomwe motsatana zimayimira mawonekedwe a turbine shaft yayikulu ndi mawonekedwe a chipinda cha Headrace; Gawo lachitatu ndi mainchesi awiri a turbine wothamanga ndi zina zofunika. Zizindikiro zoyimilira wamba mumtundu wa turbine zikuwonetsedwa patebulo 1-2.
Kwa ma turbines othamanga, gawo lachitatu pamwambapa liziwonetsedwa ngati: m'mimba mwake mwa dzina la wothamanga (CM) / kuchuluka kwa nozzles pa wothamanga aliyense × Jet diameter (CM).
M'mimba mwake mwadzina wa othamanga amitundu yosiyanasiyana yama hydraulic turbines (amene pano akutchedwa "runner diameter, omwe amafotokozedwa kawirikawiri) amatchulidwa motere.
1. M'mimba mwake ya turbine ya Francis imatanthawuza * * * m'mimba mwake mwa mbali ya cholowera chake;
2. Kuthamanga kwapakati kwa axial flow, diagonal flow and tubular turbines kumatanthawuza m'mimba mwake wothamanga m'kati mwa mphambano ndi axis ya tsamba lothamanga;
3. Mdulidwe wa turbine wa turbine wothamanga umatanthawuza kukula kwake kwa wothamanga tangent mpaka pakati pa jet.
Chitsanzo cha turbine model:
1. Hl220-lj-250 imatanthawuza turbine ya Francis yokhala ndi mtundu wothamanga wa 220, shaft yowongoka ndi volute yachitsulo, ndipo m'mimba mwake wothamanga ndi 250cm.
2. Zz560-lh-500 imatanthawuza turbine ya axial flow paddle yokhala ndi 560 yothamanga, shaft yoyima ndi volute ya konkriti, ndipo m'mimba mwake wothamanga ndi 500cm.
3. Gd600-wp-300 imatanthawuza turbine ya tubula yokhazikika yokhala ndi mtundu wa 600 wothamanga, shaft yopingasa ndi mababu, ndipo m'mimba mwake wothamanga ndi 300cm.
4.2CJ20-W-120/2 × 10. Zimatanthawuza turbine ya ndowa yokhala ndi othamanga chitsanzo cha 20. Othamanga awiri amaikidwa pa shaft imodzi. Kutalika kwa shaft yopingasa ndi yothamanga ndi 120cm. Wothamanga aliyense ali ndi ma nozzles awiri ndipo m'mimba mwake wa jet ndi 10cm.
Mutu: [zida zopangira mphamvu yamadzi] generator wa hydro
1, jenereta mtundu ndi mphamvu kufala mode (I) inaimitsidwa jenereta kukankhira kubala ili pamwamba pa ozungulira ndi anathandiza pa chimango chapamwamba.
Njira yoperekera mphamvu ya jenereta ndi:
Kulemera kwa gawo lozungulira (jenereta rotor, exciter rotor, turbine turbine runner) - mutu wopondereza - kupititsa patsogolo - nyumba ya stator - maziko; Kulemera kwa gawo lokhazikika (kuwongolera, chimango chapamwamba, jenereta stator, stator stator) - chipolopolo cha stator - base.suspended jenereta (II) generator thrust bearing ili pansi pa rotor ndi pansi pa chimango.
1. Mtundu wa ambulera wamba. Pali mayendedwe apamwamba ndi otsika.
Njira yoperekera mphamvu ya jenereta ndi:
Kulemera kwa gawo lozungulira la chigawocho - mutu wopondereza ndi kukakamiza - chimango chotsika - maziko. Chojambula chapamwamba chimangothandizira cholozera chapamwamba chonyamula ndi stator ya exciter.
2. Semi ambulera mtundu. Pali cholozera chapamwamba ndipo palibe cholozera chapansi. Jenereta nthawi zambiri imayika chimango chapamwamba pansi pa jenereta pansi.
3. Maambulera athunthu. Palibe cholozera cham'mwamba ndipo pali kalozera wam'munsi. Kulemera kwa gawo lozungulira la unit kumaperekedwa ku chivundikiro chapamwamba cha turbine yamadzi kudzera munjira yothandizira yomwe imayendetsa ndikuyika mphete yokhazikika ya turbine yamadzi kudzera pachivundikiro chapamwamba.
