Zomwe Zimayambitsa ndi Mayankho a Cavitation mu Turbine Yamadzi

1. Zomwe zimayambitsa cavitation mu turbines
Zifukwa za cavitation ya turbine ndi zovuta.Kugawa kwamphamvu mu turbine wothamanga sikuli kofanana.Mwachitsanzo, ngati wothamangayo ayikidwa pamwamba kwambiri poyerekezera ndi mlingo wa madzi otsika, 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 kuwonjezeka kwa kuthamanga, ming'oma imasungunuka, ndipo tinthu tating'onoting'ono ta madzi timagunda pakati pa thovu pa liwiro lalikulu kuti mudzaze voids kwaiye condensation, chifukwa chachikulu. hydraulic zimakhudza ndi electrochemical kanthu, kupanga Tsamba ndi anakokoloka kubala maenje ndi pores zisa, ndipo ngakhale alowerera kupanga mabowo.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 hydropower station idayamba kugwira ntchito, pakhala vuto la cavitation mu chipinda chothamanga, makamaka mu chipinda chothamanga panjira yolowera ndi kutulutsa kwa tsamba lomwelo, kupanga matumba a mpweya kuyambira 200mm m'lifupi ndi 1-6 mm kuya kwake.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 adayimitsa pang'onopang'ono njira yokonzekerayi, ndiye njira zofulumira komanso zothandiza ndi zotani?
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, sizingokhala ndi mawonekedwe abwino, komanso zimakhala ndi ubwino wa kulemera kwa kuwala, 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 kaboni 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.
