Ke hoʻokomo nei ʻoe i kahi laina wai hou a hopu i kahi kiwikā PVC. Akā inā ʻaʻole ʻoe i ʻike i kona palena kaomi, ke pilikia nei ʻoe i ka pahū ʻana o ka ʻōnaehana, kahi kahe nui, a me ka hoʻopau ʻana o ka ʻōnaehana me ke kumukūʻai nui.

ʻO ka maʻamau, ua helu ʻia kahi kiwikā pōpō PVC maʻamau o ka Schedule 40 e lawelawe i ka nui o 150 PSI (Pounds per Square Inch) ma 73°F (23°C). E emi nui ana kēia helu kaomi i ka piʻi ʻana o ka mahana o ka wai, no laila he mea nui e nānā i nā kikoʻī o ka mea hana.

ʻO kēlā helu, 150 PSI, ka pane maʻalahi. Akā, ʻoi aku ka paʻakikī o ka pane maoli, a ʻo ka hoʻomaopopo ʻana iā ia ke kī i ke kūkulu ʻana i kahi ʻōnaehana palekana a hilinaʻi hoʻi. Kūkākūkā pinepine wau i kēia me Budi, he luna kūʻai ma Indonesia. Hoʻomaʻamaʻa ʻo ia i kāna hui e nīnau i nā mea kūʻai aku ʻaʻole wale "he aha ke kaomi āu e pono ai?" akā, "he aha ka mahana?" a "pehea ʻoe e hoʻōki ai i ke kahe?" Hiki i kahi pamu ke hana i nā piʻi kaomi ma luna o ka awelika o ka ʻōnaehana. ʻO ka valve hoʻokahi wale nō ʻāpana o kahi ʻōnaehana holoʻokoʻa. ʻO ka ʻike ʻana i ka nui o ke kaomi hiki iā ia ke lawelawe ʻaʻole ia e pili ana i ka heluhelu ʻana i kahi helu; e pili ana i ka hoʻomaopopo ʻana pehea e hana ai kāu ʻōnaehana ma ke ao maoli.

He aha ka helu kaomi o kahi kiwikā PVC?

ʻIke ʻoe i ka "150 PSI" i paʻi ʻia ma ka valve, akā he aha ke ʻano maoli o ia mea? ʻO ka hoʻohana ʻana iā ia ma nā kūlana kūpono ʻole e hiki ai ke hāʻule, ʻoiai inā haʻahaʻa ke kaomi.

ʻO ka helu kaomi o kahi kiwikā PVC, maʻamau he 150 PSI no ka Papa Kuhikuhi 40, ʻo ia kona kaomi hana palekana kiʻekiʻe loa ma ka mahana o ka lumi. Ke piʻi aʻe ka mahana, palupalu ka PVC a hāʻule nui kona hiki ke lawelawe i ke kaomi.

E noʻonoʻo i ka helu kaomi e like me kona ikaika i kahi kūlana kūpono. Ma kahi mahana lumi ʻoluʻolu o 73°F (23°C), he ikaika a paʻa ka valve PVC keʻokeʻo maʻamau. AkāHe thermoplastic ka PVC, ʻo ia hoʻi, e palupalu ana me ka wela. ʻO kēia ka manaʻo koʻikoʻi loa e hoʻomaopopo ai: pono ʻoe e "hoʻemi" i ke kaomi no nā mahana kiʻekiʻe. No ka laʻana, ma 100°F (38°C), ʻo kēlā valve 150 PSI paha e palekana a hiki i ka 110 PSI. I ka manawa e hiki ai ʻoe i 140°F (60°C), ua hāʻule kona helu kiʻekiʻe loa ma kahi o 30 PSI. ʻO ia ke kumu no nā laina wai anuanu wale nō ka PVC maʻamau. No nā kaomi kiʻekiʻe a i ʻole nā ​​​​mahana kiʻekiʻe iki, e nānā ʻoePapa Kuhikuhi 80 PVC(ʻo ka maʻamau he hina ʻeleʻele), nona nā paia mānoanoa a me ka helu kaomi mua kiʻekiʻe.

Ka helu kaomi PVC vs. Mahana

He aha ka palena kaomi no ka valve pōpō?

Ua ʻike ʻoe aia ke kaomi paʻa o kāu ʻōnaehana ma lalo o ka palena. Akā, hiki i ka pani koke ʻana o ka valve ke hana i kahi spike kaomi e puhi ana ma mua o kēlā palena, e hana ana i kahi haki koke.

ʻO ka palena kaomi i ʻōlelo ʻia no ke kaomi paʻa, ʻaʻohe haʻalulu. ʻAʻole kēia palena e helu i nā ikaika hoʻololi e like mehāmare wai, he piʻi koke ʻana o ke kaomi e hiki ke uhaʻi maʻalahi i kahi kiwikā i helu ʻia no nā kaomi kiʻekiʻe loa.

ʻO ka hāmare wai ka mea pepehi leo ʻole o nā ʻāpana paipu. E noʻonoʻo i kahi paipu lōʻihi piha i ka wai e neʻe wikiwiki ana. Ke pani ʻoe i kahi valve, pono e pau koke kēlā wai e neʻe ana. Hoʻokumu ka momentum i kahi haʻalulu nui e hele ana i hope ma o ka paipu. Hiki i kēia piʻi kaomi ke 5 a 10 mau manawa o ke kaomi ʻōnaehana maʻamau. Hiki i kahi ʻōnaehana e holo ana ma 60 PSI ke ʻike i kahi piʻi o 600 PSI no kekahi manawa. ʻAʻohe valve pōpō PVC maʻamau e hiki ke kū i kēlā. Ke haʻi mau nei au iā Budi e hoʻomanaʻo i kāna mau mea kūʻai aku i kēia. Ke hāʻule kahi valve, he mea maʻalahi ke hoʻopiʻi i ka huahana. Akā pinepine, ʻo ka pilikia he hoʻolālā ʻōnaehana ʻaʻole i helu i ka hāmare wai. ʻO ka pale maikaʻi loa, ʻo ia ka pani mālie ʻana i nā valve. ʻOiai me ka valve pōpō hapaha-huli, ʻo ka hoʻohana mālie ʻana i ka lima ma luna o hoʻokahi a ʻelua paha kekona ma kahi o ka pani ʻana he ʻokoʻa nui ia.

ʻEhia ka nui o ke kaomi e hiki ai i ka PVC ke kū?

Ua koho ʻoe i ka valve kūpono, akā pehea ka paipu? ʻOi aku ka ikaika o kāu ʻōnaehana e like me kona loulou nāwaliwali loa, a ʻo ka hāʻule ʻana o ka paipu ua like ia me ka ʻino o ka hāʻule ʻana o ka valve.

ʻO ka nui o ke kaomi e hiki ai i ka PVC ke kū i luna o kona "papa kuhikuhi" a i ʻole ka mānoanoa o ka paia. ʻOi aku ka haʻahaʻa o nā helu kaomi o ka paipu PVC Papa Kuhikuhi 40 ma mua o ka paipu Papa Kuhikuhi 80 mānoanoa a ʻoi aku ka ʻoihana.

He kuhihewa maʻamau ka nānā wale ʻana i ka helu o ka valve. Pono ʻoe e hoʻohālikelike i kāu mau ʻāpana. ʻO ka paipu Schedule 40 2-'īniha, ka paipu keʻokeʻo maʻamau āu e ʻike ai ma nā wahi āpau, ua helu ʻia no kahi o 140 PSI. ʻO ka paipu Schedule 80 2-'īniha, nona nā paia mānoanoa a he hina hina ʻeleʻele pinepine, ua helu ʻia no luna o 200 PSI. ʻAʻole hiki iā ʻoe ke hoʻonui i ka mana kaomi o kāu ʻōnaehana ma ka hoʻohana ʻana i kahi valve ikaika. Inā ʻoe e hoʻokomo i kahi valve Schedule 80 (helu ʻia no 240 PSI) ma kahi paipu Schedule 40 (helu ʻia no 140 PSI), ʻo ke kaomi palekana kiʻekiʻe loa o kāu ʻōnaehana he 140 PSI wale nō. Lilo ka paipu i loulou nāwaliwali loa. No kekahi ʻōnaehana, pono ʻoe e ʻike i ka helu kaomi o kēlā me kēia ʻāpana - nā paipu, nā mea hoʻopili, a me nā valve - a hoʻolālā i kāu ʻōnaehana a puni ka ʻāpana i helu ʻia haʻahaʻa loa.

He maikaʻi anei nā kiwikā poepoe PVC?

Ke nānā nei ʻoe i kahi kiwikā palaki māmā a manaʻo ʻoe he mea makepono ia. Hiki iā ʻoe ke hilinaʻi maoli i kēia ʻāpana makepono e lilo i ʻāpana hilinaʻi i kāu ʻōnaehana wai koʻikoʻi?

ʻAe, kiʻekiʻe ke kūlanaNā kiwikā poepoe PVChe maikaʻi loa ia no kā lākou kumu i manaʻo ʻia. ʻAʻole ko lākou waiwai i ka ikaika maoli, akā i ko lākou pale piha ʻana i ka pala, ka mea e ʻoi aku ai ka hilinaʻi ma mua o ka metala ma nā noi he nui.

ʻO ka manaʻo o ka "makemake ʻole" mai ka hoʻohālikelike ʻana i ka PVC me ka metala. Akā, ua hala kēia i ke kumu.

E hana mālie ia no nā makahiki i loko o kahi ʻano e luku ai i ka metala. Lanakila ʻo Budi i nā mea kūʻai aku kānalua ma ka hoʻoponopono hou ʻana i ka nīnau. ʻAʻole ka nīnau "ua lawa ka plastic?" ʻO ka nīnau "hiki i ka metala ke ola i ka hana?" No ka kaohi wai anuanu, ʻoi aku hoʻi ma kahi o nā kemika a i ʻole ka paʻakai, ʻaʻole wale kahi koho maikaʻi kahi valve PVC i hana maikaʻi ʻia; ʻo ia ke koho akamai, hilinaʻi, a ʻoi aku ka maikaʻi o ke kumukūʻai no ka wā lōʻihi.
