1. Izizathu ze-cavitation kwii-turbines
Izizathu ze-cavitation ye-turbine ziyinkimbinkimbi.Ukuhanjiswa koxinzelelo kwimbaleki ye-injini yomoya ayilingani.Ngokomzekelo, ukuba umgijimi ufakwe phezulu kakhulu ngokubhekiselele kwinqanaba lamanzi asezantsi, xa amanzi ahamba ngesantya esiphezulu ehamba kwindawo yoxinzelelo oluphantsi, kulula ukufikelela kuxinzelelo lwe-vaporization kunye nokuvelisa ama-bubbles.Xa amanzi ehamba kwindawo yoxinzelelo oluphezulu, ngenxa yokunyuka koxinzelelo, amaqamza ayancipha, kwaye amaqhekeza okuhamba kwamanzi abetha embindini weebhubhu ngesantya esiphezulu ukuze azalise i-voids eyenziwa yi-condensation, ebangela ukuba kukhulu. impembelelo ye-hydraulic kunye nesenzo se-electrochemical, ukwenza I-blade ikhukuliswe ukuvelisa imingxuma kunye ne-honeycomb pores, kwaye yangena ngaphakathi ukwenza imingxuma.Umonakalo weCavitation ungakhokelela ekunciphiseni ukusebenza kwezixhobo okanye nokuba umonakalo, okubangelwa yimiphumo emikhulu kunye neempembelelo.
2. Intshayelelo kwiiCase of Turbine Cavitation
Ekubeni iyunithi ye-tubular turbine yesikhululo sombane we-hydropower isetyenziswe, kukho ingxaki ye-cavitation kwigumbi lomgijimi, ngokukodwa kwigumbi lokugijima kwindawo yokungena kunye nokuphuma kwe-blade efanayo, ukwenza iipokotshi zomoya ukusuka kwi-200mm ububanzi kunye 1-6mm ubunzulu.Ummandla we-cavitation kuwo wonke umjikelezo, ngokukodwa inxalenye ephezulu yegumbi lomgijimi, ivelele ngakumbi, kwaye ubunzulu be-cavitation yi-10-20mm.Nangona inkampani iye yamkela iindlela ezifana nokulungisa i-welding, ayizange ilawule ngokufanelekileyo i-cavitation phenomenon.Kwaye kunye nenkqubela phambili yamaxesha, iinkampani ezininzi ziye zayiphelisa ngokuthe ngcembe le ndlela yokugcinwa kwendabuko, ngoko zeziphi izisombululo ezikhawulezayo nezisebenzayo?
Okwangoku, iteknoloji ye-Soleil carbon nano-polymer isetyenziswa ngokubanzi ukulawula i-cavitation phenomenon ye-turbine yamanzi.Esi sixhobo sisixhobo esisebenzayo esiveliswa yi-resin ephezulu yokusebenza kunye ne-carbon nano-inorganic material ngokusebenzisa iteknoloji ye-polymerization.Inokuthi ibambelele kwiintsimbi ezahlukeneyo, ikhonkrithi, iglasi, i-PVC, irabha kunye nezinye izinto.Emva kokuba impahla isetyenziswe kumphezulu we-injini yomoya, ayinayo kuphela iimpawu zokulinganisa kakuhle, kodwa ineenzuzo zobunzima bokukhanya, ukuxhathisa ukubola, ukuxhathisa ukunxiba, njl., eziluncedo ekusebenzeni okuzinzile kwe-injini yomoya. .Ngokukodwa kwizixhobo ezijikelezayo, umphumo wokulondoloza amandla uya kuphuculwa kakhulu emva kokudibanisa phezulu, kwaye ingxaki yokulahlekelwa kwamandla iya kulawulwa.
Okwesithathu, isisombululo kwi-cavitation ye-turbine
1. Yenza unyango lwe-surface degreasing, sebenzisa kuqala i-carbon arc air gouging ukucwangcisa i-cavitation layer, kwaye ususe i-metal metal layer;
2. Emva koko sebenzisa i-sandblasting ukususa umhlwa;
3. Hlangana kwaye usebenzise i-carbon nano-polymer material, kwaye ukhuhle kunye ne-benchmark kunye nerula yetemplate;
4. Izinto eziphathekayo zinyangwa ukuqinisekisa ukuba izinto eziphathekayo zinyangekile ngokupheleleyo;
5. Khangela indawo elungisiweyo kwaye uyenze ihambelane nobukhulu bereferensi.
