He mea nui ka puka wai kila no ka hoʻomalu ʻana i ka pae wai i loko o nā hale hydraulic e like me ke kahua hydropower, ka waihona wai, ka wai kila a me ka laka moku. Pono e hoʻoluʻu ʻia i lalo o ka wai no ka manawa lōʻihi, me ka hoʻololi pinepine ʻana o ka maloʻo a me ka pulu i ka wā e wehe ai a pani ai, a holoi ʻia e ke kahe wai wikiwiki. Ma ke ʻano kūikawā, ua hoʻopilikia ʻia ka ʻāpana laina wai e ka wai, ka lā a me nā meaola wai, a me nā nalu wai, ka lepo, ka hau a me nā mea lana ʻē aʻe, a maʻalahi ke kila e ʻānai, Hoʻemi nui ia i ka hiki ke hāpai i ka puka kila a hoʻopilikia nui i ka palekana o ka ʻenekinia hydraulic. Pale ʻia kekahi e ka uhi ʻana, kahi e hāʻule pinepine ai ma hope o 3 ~ 5 mau makahiki o ka hoʻohana ʻana, me ka hana haʻahaʻa a me ke kumukūʻai mālama kiʻekiʻe.

ʻAʻole wale ka hopena o ka palaho i ka hana palekana o ka hale, akā hoʻopau pū kekahi i ka nui o ke kanaka, nā mea a me nā kumuwaiwai kālā e hana i nā hana anti-corrosion. Wahi a nā helu helu o kekahi mau papahana puka sluice, ʻo ka lilo makahiki no ka puka anti-corrosion e pili ana i ka hapalua o ke kumukūʻai mālama makahiki. I ka manawa like, pono e hoʻoneʻe ʻia kahi nui o ka poʻe hana e wehe i ka popo, ka pena a i ʻole ka pīpī. No laila, i mea e kāohi pono ai i ka palaho o ke kila, e hoʻolōʻihi i ke ola lawelawe o ka puka kila a hōʻoia i ka pono a me ka palekana o nā papahana mālama wai a me ka hydropower, ua huki nui ʻia ka pilikia anti-corrosion lōʻihi o ka puka kila.

Kaiapuni palaho o ka puka hao kila a me nā mea e pili ana i ka palaho:

1. Kaiapuni ʻino o ka puka sluice kila

ʻO kekahi mau puka hao kila a me nā hale kila i nā papahana mālama wai a me nā papahana hydropower e hoʻoluʻu ʻia i loko o nā ʻano wai like ʻole (wai kai, wai maʻemaʻe, wai hoʻoneoneo ʻoihana, a me nā mea ʻē aʻe) no ka manawa lōʻihi; Aia kekahi i loko o kahi ʻano maloʻo a pulu ma muli o nā loli o ka pae wai a i ʻole ka wehe ʻana a me ka pani ʻana o ka puka; e hoʻopilikia ʻia kekahi e ke kahe wai wikiwiki a me ka friction o ka sediment, nā ʻōpala lana a me ka hau; Hoʻopilikia ʻia ka ʻāpana ma luna o ka wai a i ʻole ma luna o ka wai e ka lewa pulu o ka mahu wai a me ka noe wai pīpī; Hoʻopilikia ʻia nā hale e hana ana i ka lewa e ka lā a me ka ea. No ka mea he maikaʻi ʻole ke kaiapuni hana o ka puka hydraulic a he nui nā mea hoʻohuli, pono e kālailai i nā mea pala.

2. Nā kumu hoʻopilikia

(1) nā kumu aniau: ʻo nā ʻāpana wai o ka puka hao kila e maʻalahi ke pala i ka lā, ka ua a me ka lewa pulu.

(2) ke kūlana o ka ʻili o ke kūkulu kila: ʻo ka ʻino, ka pōʻino mechanical, ka cavitation, nā kīnā kuʻihao, nā hakahaka, a me nā mea ʻē aʻe he hopena nui i ka pala.

(3) ke kaumaha a me ka deformation: ʻo ka nui o ke kaumaha a me ka deformation, ʻoi aku ka ʻino o ka corrosion.

(4) ke ʻano o ka wai: haʻahaʻa ka paʻakai o ka wai maʻemaʻe, a ʻokoʻa ka pala o ka puka ma muli o kona ʻano kemika a me ka haumia; He kiʻekiʻe ka paʻakai o ka wai kai a he maikaʻi ka conductivity. Loaʻa i ka wai kai ka nui o nā ion chloride, kahi mea e pala loa ai i ke kila. ʻOi aku ka koʻikoʻi o ka pala o ka puka kila i loko o ka wai kai ma mua o ka wai maʻemaʻe.
