ʻO ka hui luna o ka pū puhi he mea hana nui no ka hoʻoheheʻe ʻana i nā pūnāwai aila. Hana ʻia ia me nā mea waiwai kiʻekiʻe me ka hana hilinaʻi a me ka hoʻolālā pololei. Hoʻokumu nui ʻia me ka pūpū, ka lua i loko, ke sila, ka hui a me ka mīkini hoʻouna.
ʻO ka mea i hoʻohana ʻia i loko o kēia huahana he ikaika kiʻekiʻe loa a me ka pale ʻana i ka corrosion, a hiki ke hoʻohana ʻia no ka manawa lōʻihi me ka ʻole o ka pōʻino i ka hana ʻino. I ka manawa like, loaʻa iā ia ka hoʻolālā paʻa a me ka hoʻonohonoho kūpono, a hiki ke hoʻohana ʻia me nā pū perforating like ʻole.
I ke kaʻina o ka hoʻohana ʻana, hiki i ka hui luna o ka pū perforating ke hoʻomaikaʻi maikaʻi i ka pololei a me ke kūpaʻa o ka perforating, pēlā e hoʻomaikaʻi ai i ka holomua o ka ʻaila perforating. Loaʻa iā ia kahi mīkini hoʻouna pololei loa, hiki ke hōʻoia i ka hoʻonohonoho pololei ʻana o ka pū perforating a me ka mana o ka hohonu perforating.
Loaʻa i ka huahana ka hoʻohana ikaika a me ka hilinaʻi. Hiki ke hoʻohana ʻia i loko o nā kaiapuni ʻaila hinu a hiki ke hoʻololi i nā koi perforation like ʻole. Eia kekahi, ma muli o kāna hoʻolālā pololei a me ka hana hilinaʻi, hiki iā ia ke hōʻemi nui i ka helu hemahema o ka perforation a me ka hiki ke pilikia, no laila e hōʻoia i ka hana maʻamau o nā pūnāwai aila.
I ka pōkole, ʻo ka hui kiʻekiʻe o ka pū perforating he mea hana kiʻekiʻe a paʻa i ka ʻaila maikaʻi, nona ka hana maikaʻi loa a me ka maikaʻi hilinaʻi, hiki ke hoʻomaikaʻi i ka helu kūleʻa o ka hana perforating a me ka hana ʻana i ka ʻaila, a he ʻāpana pono o ka aila. maikaʻi ka perforating.
