I kēia mau lā, ua hana maikaʻi ʻia kahi pūʻulu o nā ʻīpuka square ma ka hale hana Jinbin. ʻO kakiwi puna waihana ʻia i kēia manawa me ka mea hao ductile a uhi ʻia me ka uhi pauka epoxy. He ikaika kiʻekiʻe ka hao Ductile, paʻakikī kiʻekiʻe, a me ke kūpaʻa ʻaʻahu maikaʻi, a hiki ke kū i ka ikaika nui a me ka hopena. Hāʻawi ka epoxy pauka i ka hana anti-corrosion maikaʻi loa no kapuka wai, e hooloihi ana i kona ola lawelawe. Hiki i kēia hui waiwai ke mālama i ka hana paʻa i nā ʻano ʻino like ʻole.

ʻO kēia pūʻulu huinahāpuka puka waihele mai ʻelua nui, 600×600 a me 800×800. Hoʻokō nā ʻano nui like ʻole i nā pono like ʻole o nā mea kūʻai aku a hāʻawi i nā hopena hilinaʻi no ka ʻenehana hydraulic a me nā papahana ʻoihana. Ma ke kaʻina hana, mālama pono ka hale hana i kēlā me kēia loulou, mai ke kūʻai ʻana i nā mea waiwai a hiki i ka hana ʻana a me ka hana ʻana, a ma hope i ka nānā ʻana i ka maikaʻi, e hōʻoia i ka maikaʻi o ka puka i nā kūlana kiʻekiʻe.

I mea e hōʻoiaʻiʻo ai i ka pololei a me ka maikaʻi o ka ʻīpuka, ua lawe ka hale hana i nā mea hana a me nā kaʻina hana. ʻO nā mea mīkini mīkini CNC kiʻekiʻe e hōʻoia i ka pololei o ka nui o ka valve sluice gate, e ʻae i kēlā me kēia puka e kūpono i ke kūlana hoʻonohonoho. I kēia manawa, ʻo ke kaʻina hana wiliwili ʻoihana e hōʻoia i ka ikaika o ka ʻīpuka, hiki iā ia ke kū i ke kaomi wai nui. Ma ke ʻano o ka mālama ʻana i ka ʻili, ʻaʻole hoʻomaikaʻi wale ka uhi ʻana o ka epoxy powder coating i ka aesthetics o ka ʻīpuka, akā hoʻonui pū i kāna hana anti-corrosion.

ʻAʻole hiki ke hoʻokaʻawale ʻia ka paʻa ʻana o kēia pūʻulu o nā puka pā mai ka hana paʻakikī o nā limahana a pau o ka hale hana. Mai ka hoʻolālā maikaʻi ʻana o nā mea hoʻolālā i ka hana akamai o nā limahana hana, a laila i ka nānā pono ʻana o nā mea nānā maikaʻi, ua hāʻawi nā mea a pau i ko lākou ikaika ponoʻī i ka hana ʻana i nā puka. Hoʻopaʻa lākou i kēlā me kēia puka (penstock manufacturers) e hoʻokō i nā koi o ka mea kūʻai aku me ka manaʻo kiʻekiʻe o ke kuleana a me ka ʻoihana.

Ke nānā nei i mua i ka wā e hiki mai ana, e hoʻomau ʻo Jinbin i ka manaʻo o ka ʻoihana "ʻoi aku ka maikaʻi, ka mea kūʻai mua" a hoʻomaikaʻi mau i ka maikaʻi o ka huahana a me ka pae lawelawe. E hoʻomau ka hale hana i ka hoʻonui ʻana i ka noiʻi a me ka hoʻomohala ʻana, e hoʻolauna i nā huahana kiʻekiʻe a me nā huahana kiʻekiʻe, a e hāʻawi nui aku i ka hoʻomohala ʻana i ka ʻenekinia mālama wai a me nā māla ʻoihana. I ka manawa like, e hoʻonui ikaika ka hale hana i kāna mākeke a hoʻokumu i nā pilina paʻa paʻa lōʻihi me nā mea kūʻai aku e hana pū i kahi wā e hiki mai ana.
