Zomwe Zimayambitsa ndi Mayankho a Cavitation mu Turbine Yamadzi

1. Zomwe zimayambitsa cavitation mu turbines
Zifukwa za cavitation ya turbine ndi zovuta. Kugawika kwamphamvu mu turbine wothamanga sikuli kofanana. Mwachitsanzo, ngati wothamangayo aikidwa pamwamba kwambiri poyerekezera ndi mlingo wa madzi akumunsi, pamene madzi othamanga kwambiri amayenda m'dera lotsika kwambiri, n'zosavuta kuti afikire kuthamanga kwa vaporization ndikupanga thovu. Pamene madzi akuyenda kumalo othamanga kwambiri, chifukwa cha kuchuluka kwa kuthamanga, ming'oma imasungunuka, ndipo tinthu tating'onoting'ono ta madzi timagunda pakati pa thovu pa liwiro lalikulu kuti mudzaze voids opangidwa ndi condensation, zomwe zimachititsa kuti hydraulic imakhudza kwambiri komanso electrochemical kanthu, kupanga tsambalo likuphwanyidwa kuti lipange maenje ndi zisa za njuchi zomwe zimapangidwira pores. Kuwonongeka kwa cavitation kungayambitse kuchepa kwa zida kapena kuwonongeka, zomwe zimabweretsa zotsatira zazikulu ndi zotsatira zake.

2. Chiyambi cha Milandu ya Turbine Cavitation
Popeza kuti tubular turbine unit ya siteshoni ya hydropower yakhazikitsidwa, pakhala vuto la cavitation mu chipinda chothamanga, makamaka mu chipinda chothamanga pa malo olowera ndi kutuluka kwa tsamba lomwelo, kupanga matumba a mpweya kuyambira 200mm m'lifupi ndi 1-6mm mozama. Malo a cavitation ponseponse, makamaka kumtunda kwa chipinda chothamanga, ndi chodziwika bwino, ndipo kuya kwa cavitation ndi 10-20mm. Ngakhale kampani yatengera njira monga kukonza kuwotcherera, si bwino ankalamulira cavitation chodabwitsa. Ndipo m'kupita kwa nthawi, makampani ambiri asiya pang'onopang'ono njira yokonza mwambowu, ndiye njira zofulumira komanso zothandiza ndi ziti?
Pakali pano, Soleil carbon nano-polymer zakuthupi luso chimagwiritsidwa ntchito kulamulira cavitation chodabwitsa cha turbine madzi. Izi ndizinthu zophatikizika zomwe zimapangidwa ndi utomoni wochita bwino kwambiri komanso zinthu za carbon nano-inorganic kudzera muukadaulo wa polymerization. Iwo akhoza amamatira zitsulo zosiyanasiyana, konkire, galasi, PVC, mphira ndi zipangizo zina. Zinthuzo zikagwiritsidwa ntchito pamwamba pa turbine, sizimangokhala ndi makhalidwe abwino, komanso zimakhala ndi ubwino wa kulemera kwake, kukana kwa dzimbiri, kukana kuvala, ndi zina zotero, zomwe zimapindulitsa pakugwira ntchito kokhazikika kwa turbine. Makamaka pazida zozungulira, mphamvu yopulumutsa mphamvu idzakhala yabwino kwambiri pambuyo pophatikizana pamwamba, ndipo vuto la kutaya mphamvu lidzayendetsedwa.

Chachitatu, njira yothetsera cavitation ya turbine
1. Chitani pamwamba degreasing mankhwala, choyamba ntchito carbon arc mpweya gouging kukonzekera pa cavitation wosanjikiza, ndi kuchotsa lotayirira zitsulo wosanjikiza;
2. Kenako gwiritsani ntchito sandblasting kuchotsa dzimbiri;
3. Gwirizanitsani ndikugwiritsa ntchito zida za carbon nano-polymer, ndikuphwanya motsatira benchmark ndi wolamulira wa template;
4. Zinthuzo zimachiritsidwa kuti zitsimikizidwe kuti zachiritsidwa kwathunthu;
5. Yang'anani malo okonzedwa ndikupangitsa kuti ikhale yogwirizana ndi kukula kwake.
