He hopena electrolyte ka wai kai e loaʻa ana nā paʻakai he nui a hoʻoheheʻe i kahi nui o ka oxygen. Hoʻopau ʻia ka hapa nui o nā mea metala i loko o ka wai kai e ka electrochemical. Nui loa ka nui o ka ion chloride i loko o ka wai kai, kahi e hoʻonui ai i ka wikiwiki o ka pala. I ka manawa like, hoʻopuka nā ʻāpana one a me ke one i ke kaumaha reciprocating haʻahaʻa a me ka hopena i nā ʻāpana metala. I nā makahiki i hala iho nei, me ka wikiwiki o ka hoʻomohala ʻana o ka hoʻomohala ʻana a me ka hoʻohana ʻana i ke kai, ke kūkulu nui ʻana o nā papahana mana nukelea kahakai a me ka hoʻolaha ʻana i ka ʻoihana desalination wai kai, ua lilo ka hoʻohana ʻana i nā valves butterfly pale wai kai i mea ākea. No kēia hopena, ua hoʻomohala ʻo NSEN i kahi valve butterfly pale wai kai i kūpono no ka ʻoihana moana, ka hoʻoluʻu wai kai nukelea a me nā ʻoihana ʻē aʻe.

ʻO nā kiwikā pepeke wai maʻamau e kū i ka wai kai, i mea e hoʻololi ai i ka pala o nā ion chloride i loko o ka wai kai, ʻo ke kino kiwikā, ka papa pepeke a me nā mea pono ʻē aʻe i hana pinepine ʻia me ke kila kila duplex, ka titanium alloy a me ke keleawe alumini. ʻAʻole hiki i nā hemahema ke hoʻokō piha i nā pono o nā kūlana wai kai. No ka laʻana, he hana maikaʻi loa ka kiwikā pepeke titanium alloy ma nā ʻano āpau, akā he paʻakikī ka ʻenehana hoʻoheheʻe o ka titanium a me ka titanium alloy, a he paʻakikī ke ʻano o ka loaʻa ʻana o nā titanium alloy castings, paʻakikī ke hana, a he pipiʻi loa ke kumukūʻai. Inā hana ʻia ka kiwikā pepeke me ke kila kila duplex, hiki iā ia ke kūʻē i ka pala o nā ion chloride, akā ʻaʻole maikaʻi ke kūpaʻa ʻana i ka erosion. Hiki ke hōʻino maʻalahi ʻia ke awa kahe a me ka ʻili sila e ka erosion, e hoʻoheheʻe ana i ka ʻili sila o ka kiwikā pepeke.

Hāʻawi ʻo NSEN i kahi hopena kūpono no kā mākou mea kūʻai aku-Kiwikā Pepeiao Sila Laholio Kūpaʻa Kai, ua hoʻolālā ʻia kēia moʻo me ka hoʻolālā offset pālua a me kahi mea sila palupalu e like me EPDM a i ʻole ka mea PTFE.

Mea maʻamau:

Kino WCB + uhi pale ma ke awa
