ʻO nā kumu a me nā hopena o ka Cavitation i ka wai turbine

1. Nā kumu o ka cavitation i nā turbines
He paʻakikī nā kumu o ka cavitation o ka turbine.ʻAʻole like ka puʻunaue puʻe i ka mea holo turbine.No ka laʻana, inā hoʻokomo ʻia ka mea holo kiʻekiʻe e pili ana i ka pae wai o lalo, i ka wā e kahe ai ka wai wikiwiki i ka wahi haʻahaʻa haʻahaʻa, ua maʻalahi ke kiʻi ʻana i ke kaomi vaporization a hoʻopuka i nā ʻōhū.Ke kahe ka wai i ka wahi puʻe kiʻekiʻe, ma muli o ka piʻi ʻana o ke kaomi, hoʻopaʻa ʻia nā ʻōpala, a paʻi nā ʻāpana o ka wai i ke kikowaena o nā ʻōpū i ka wikiwiki nui e hoʻopiha i nā hakahaka i hana ʻia e ka condensation, e hopena i ka nui. ʻO ka hopena hydraulic a me ka hana electrochemical, e hana ana Hoʻopau ʻia ka ʻili e hana i nā lua a me nā pores honeycomb, a komo pū i puka.Hiki i ka hōʻino ʻana i ka cavitation ke alakaʻi i ka hoʻemi ʻana i ka pono o nā mea hana a i ʻole ka pōʻino, e hopena i nā hopena nui a me nā hopena.

2. Introduction to Cases of Turbine Cavitation
Ma muli o ka hoʻokomo ʻia ʻana o ka tubular turbine unit o kahi hydropower station, aia kahi pilikia cavitation i loko o ke keʻena kukini, ʻoi loa i loko o ke keʻena runner ma ka inlet a me ka puka o ka lau like, e hana ana i nā ʻeke ea mai ka 200mm ka laulā a 1-6mm ka hohonu.ʻO ka ʻāpana cavitation ma luna o ka pōʻai, ʻoi aku ka nui o ka ʻaoʻao o luna o ke keʻena holo, ʻoi aku ka kaulana, a ʻo ka hohonu o ka cavitation he 10-20mm.ʻOiai ua hoʻohana ka ʻoihana i nā ʻano e like me ka hoʻoponopono ʻana i ka welding, ʻaʻole ia i kāohi pono i ka hanana cavitation.A me ka holomua o ka manawa, nui nā hui i hoʻopau mālie i kēia ʻano mālama maʻamau, no laila he aha nā hopena wikiwiki a maikaʻi?
I kēia manawa, hoʻohana nui ʻia ʻo Soleil carbon nano-polymer material technology e hoʻomalu i ka hanana cavitation o ka turbine wai.ʻO kēia mea he mea hoʻohui waiwai i hana ʻia e ka resin kiʻekiʻe a me ka carbon nano-inorganic material ma o ka ʻenehana polymerization.Hiki ke hoʻopaʻa ʻia i nā metala like ʻole, ke kō, ke aniani, ka PVC, ka lāʻau a me nā mea ʻē aʻe.Ma hope o ka hoʻopili ʻia ʻana o ka mea i ka ʻili o ka turbine, ʻaʻole wale ia nā hiʻohiʻona o ka pae maikaʻi, akā loaʻa nō hoʻi nā pōmaikaʻi o ka paona māmā, ka pale ʻana i ka corrosion, ke kūpaʻa ʻana, a me nā mea ʻē aʻe, he mea pono i ka hana paʻa o ka turbine. .Maikaʻi no ka hoʻololi ʻana i nā mea hana, e hoʻomaikaʻi maikaʻi ʻia ka hopena mālama ola ma hope o ka hui ʻana i ka ʻili, a e hoʻomalu ʻia ka pilikia o ka mana.

ʻO ke kolu, ka hopena i ka cavitation o ka turbine
1. E hoʻokō i ka hoʻomaʻemaʻe ʻana i ka ʻili, e hoʻohana mua i ka ea arc carbon i ka hoʻolālā ʻana i ka papa cavitation, a wehe i ka ʻāpana metala wehe;
2. A laila hoʻohana i ka sandblasting e wehe i ka ʻōpala;
3. E hoʻokuʻikahi a e hoʻopili i ka mea kalapona nano-polymer, a e ʻoka ma ka pae ʻāina me kahi lula template;
4. Hoʻōla ʻia ka mea i mea e hōʻoia ai ua hoʻōla loa ʻia ka mea;
5. E nānā i ka ʻili i hoʻoponopono ʻia a e kūlike me ka nui kuhikuhi.
