Zifukwa ndi Mayankho a Cavitation mu Water Turbine

1. Zomwe zimayambitsa kutsekeka kwa ma turbine
Zifukwa za cavitation ya turbine ndi zovuta. Kugawa kwa kuthamanga mu turbine runner sikofanana. Mwachitsanzo, ngati turbine yayikidwa pamwamba kwambiri poyerekeza ndi madzi otsika, pamene madzi othamanga kwambiri akuyenda kudutsa m'dera lotsika, zimakhala zosavuta kufika pa vaporization pressure ndikupanga thovu. Madzi akamapita kudera lokwera kwambiri, chifukwa cha kuwonjezeka kwa kuthamanga, thovulo limasungunuka, ndipo tinthu ta madzi timagunda pakati pa thovulo pa liwiro lalikulu kuti tidzaze malo opanda kanthu omwe amapangidwa ndi condensation, zomwe zimapangitsa kuti hydraulic impact yayikulu ndi electrochemical action, zomwe zimapangitsa kuti tsambalo liwonongeke kuti lipange maenje ndi ming'alu ya uchi, ndipo ngakhale kulowa mkati kuti apange mabowo. Kuwonongeka kwa cavitation kungayambitse kuchepa kwa magwiridwe antchito a zida kapena kuwonongeka, zomwe zimapangitsa kuti pakhale zotsatirapo zazikulu komanso zotsatirapo.

2. Chiyambi cha Milandu ya Turbine Cavitation
Popeza kuti gawo la tubular turbine la siteshoni yamagetsi ya madzi layamba kugwira ntchito, pakhala vuto la cavitation mu runner chamber, makamaka mu runner chamber pamalo olowera ndi kutuluka kwa tsamba lomwelo, ndikupanga matumba a mpweya kuyambira 200mm m'lifupi ndi 1-6mm kuya. Malo otseguka kuzungulira konse, makamaka gawo lapamwamba la runner chamber, ndi owonekera kwambiri, ndipo kuya kwa cavitation ndi 10-20mm. Ngakhale kampaniyo yatenga njira monga kukonza welding, sinalamulire bwino vutoli la cavitation. Ndipo ndi kupita patsogolo kwa nthawi, makampani ambiri pang'onopang'ono asiya njira yosamalira yachikhalidweyi, ndiye mayankho achangu komanso ogwira mtima ndi ati?
Pakadali pano, ukadaulo wa Soleil carbon nano-polymer umagwiritsidwa ntchito kwambiri kuwongolera momwe turbine yamadzi imagwirira ntchito. Zinthuzi ndi zinthu zophatikizika zomwe zimapangidwa ndi utomoni wapamwamba komanso zinthu zopanda kaboni pogwiritsa ntchito ukadaulo wa polymerization. Zitha kumamatiridwa ku zitsulo zosiyanasiyana, konkriti, galasi, PVC, rabala ndi zinthu zina. Zinthuzo zikagwiritsidwa ntchito pamwamba pa turbine, sizimangokhala ndi makhalidwe abwino, komanso zimakhala ndi ubwino wolemera pang'ono, kukana dzimbiri, kukana kuvala, ndi zina zotero, zomwe zimathandiza pakugwira ntchito bwino kwa turbine. Makamaka pazida zozungulira, mphamvu yosunga mphamvu idzasintha kwambiri ikaphatikizidwa pamwamba, ndipo vuto la kutaya mphamvu lidzawongoleredwa.

Chachitatu, njira yothetsera cavitation ya turbine
1. Chitani mankhwala ochotsera mafuta pamwamba, choyamba gwiritsani ntchito choboola mpweya wa carbon arc kuti muchotse choboola cha cavitation, ndikuchotsa choboola chachitsulo chosasunthika;
2. Kenako gwiritsani ntchito kuphulika kwa mchenga kuti muchotse dzimbiri;
3. Gwirizanitsani ndikugwiritsa ntchito zinthu za carbon nano-polymer, ndikukanda motsatira benchmark ndi template ruler;
4. Chovalacho chimatsukidwa kuti chitsimikizire kuti chatsukidwa bwino;
5. Yang'anani malo okonzedwawo ndipo muwapange kuti agwirizane ndi kukula kwa malo ofunikira.
