Ke kau nei ʻoe i kahi laina wai hou a hopu i ka valve PVC. Akā inā ʻaʻole ʻoe i ʻike i ka palena o ke kaomi ʻana, ke pilikia nei ʻoe i ka pōʻino, ka waikahe nui, a me ka hoʻopau ʻana o ka ʻōnaehana kumu kūʻai.

Hoʻonohonoho maʻamau ʻia kahi pahu pōpō pōpō PVC maʻamau 40 no ka mālama ʻana i kahi kiʻekiʻe o 150 PSI (Pounds per Square Inch) ma 73°F (23°C). Ke emi nui nei 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 he kī ia i ke kūkulu ʻana i kahi ʻōnaehana palekana a hilinaʻi. Kūkākūkā pinepine au 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 e pono ai ʻoe?" akā, "he aha ka mahana?" a "pehea ʻoe e hoʻōki ai i ke kahe?" Hiki i ka pauma ke hana i nā pihi kaomi ma mua o ka awelika o ka ʻōnaehana. ʻO ka valve kahi ʻāpana o ka ʻōnaehana holoʻokoʻa. ʻO ka ʻike ʻana i ka nui o ke kaomi ʻana ʻaʻole ia e pili ana i ka heluhelu ʻana i kahi helu; e pili ana i ka hoʻomaopopo ʻana i ke ʻano o kāu ʻōnaehana ma ke ao maoli.

He aha ke ʻano o ke kaomi ʻana o ka valve PVC?

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

ʻO ka helu kaomi o ka valve PVC, maʻa mau ʻo 150 PSI no ka Hōʻike 40, ʻo ia ka nui o ke kaomi hana palekana ma ka lumi wela. Ke piʻi aʻe ka mahana, palupalu ka PVC a hāʻule nui kona hiki ke mālama i ke kaomi.

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

ʻO ka helu pāʻani PVC me ka Mahana

He aha ka palena o ke kaomi no ka pahu kinipopo?

Ua ʻike ʻoe ʻoi aku ka palekana o ke kaomi paʻa o kāu ʻōnaehana ma lalo o ka palena. Akā, hiki i ka pani ʻana o ka valve hiki ke hana i kahi puʻupuʻu puʻupuʻu e pā ana ma mua o kēlā palena, e hana ai i ka haki koke.

ʻO ka palena kaomi i ʻōlelo ʻia no ke kaomi paʻa ʻole. ʻAʻole pili kēia palena i nā mana ikaika e like mehāmare wai, he piʻi piʻi hikiwawe e hiki ke uhaki i ka valve i helu ʻia no nā kaomi kiʻekiʻe.

ʻO ka hāmare wai ka mea pepehi hāmau o nā ʻāpana paipu. E noʻonoʻo i kahi paipu lōʻihi piha i ka wai e neʻe wikiwiki ana. Ke pani ʻoe i kahi kiwi, pono e hoʻōki koke kēlā wai holo. Hoʻokumu ka momentum i kahi hawewe haʻalulu nui e hoʻi i hope ma ka paipu. Hiki ke 5 a 10 ka nui o ke kaomi ʻana o ka ʻōnaehana maʻamau. Hiki i kahi ʻōnaehana holo ma 60 PSI ke ʻike i kahi spike o 600 PSI. ʻAʻole hiki ke pale i kēlā mea. ʻŌlelo mau wau iā Budi e hoʻomanaʻo i kāna mau mea kūʻai ʻaelike i kēia. Ke hāʻule ka valve, maʻalahi ka hoʻopiʻi ʻana i ka huahana. Akā pinepine, ʻo ka pilikia he hoʻolālā ʻōnaehana ʻaʻole helu i ka hāmare wai. ʻO ka pale maikaʻi loa e pani mālie i nā kiwi. ʻOiai me ka pahu pōpō ʻehā ʻehā, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka lima ma luna o hoʻokahi kekona a ʻelua paha ma mua o ka pani ʻana.

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

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

ʻO ka nui o ka paʻi PVC hiki ke kūpaʻa ma muli o kāna "papahana" a i ʻole ka mānoanoa o ka pā. He haʻahaʻa haʻahaʻa ka paipu PVC ma ka Papa Hōʻike 40 ma mua o ka paipu Papa 80 o ka pā mānoanoa, ʻoi aku ka ʻoihana.

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

Hoʻohālikelike Hoʻohālikelike Paipu (Laʻana: PVC 2-inihi)

He mea maikaʻi paha nā kiwi pōpō PVC?

Ke nānā nei ʻoe i kahi pahu plastik māmā a manaʻo ʻoe he ʻuʻuku. Hiki iā ʻoe ke hilinaʻi i kēia ʻāpana kūʻai ʻole he mea hilinaʻi i kāu ʻōnaehana wai koʻikoʻi?

ʻAe, kūlana kiʻekiʻeʻO nā kiwi pōpō PVCmaikaʻi loa no ko lākou manaʻo. ʻAʻole ko lākou waiwai i ka ikaika ʻoi loa, akā i ko lākou pale ʻana i ka corrosion, ʻoi aku ka hilinaʻi ma mua o ka metala i nā noi he nui.

ʻO ka manaʻo o ka "cheapness" mai ka hoʻohālikelike ʻana i ka PVC i ka metala. Akā, hala kēia i ka manaʻo. Ma nā noi wai he nui, ʻoi aku hoʻi i ka mahiʻai, ka iʻa a i ʻole nā ​​​​pūnaewele wai, ʻo ka corrosion ke kumu nui o ka hāʻule. ʻO ke keleawe a i ʻole ka pahu hao e ʻōpala a hopu i ka manawa. ʻO kahi valve PVC maikaʻi, i hana ʻia mai ka 100% resin puʻupaʻa me nā noho PTFE maʻemaʻe a me nā apo O-redundant, ʻaʻole ia. E holo mālie ia no nā makahiki i loko o kahi kaiapuni e hoʻopau ai i ka metala. Ua lanakila ʻo Budi ma luna o nā mea kūʻai kānalua ma ka hoʻoponopono hou ʻana i ka nīnau. ʻAʻole ka nīnau "ua lawa ka plastik?" ʻO ka nīnau "hiki ke ola metala i ka hana?" No ka hoʻomalu ʻana i ka wai anuanu, ʻoi aku ka maikaʻi ma kahi o nā kemika a i ʻole ka paʻakai, ʻaʻole kahi koho maikaʻi ʻo PVC i hana maikaʻi ʻia; ʻo ia ka koho ʻoi aku ka naʻauao, ʻoi aku ka hilinaʻi, a ʻoi aku ka uku no ka wā lōʻihi.

Ka hopena

Hiki ke hoʻopaʻa ʻia kahi pahu pōpō PVC i ka 150 PSI ma ka lumi wela. Aia kona waiwai maoli i ka pale ʻana i ka corrosion, akā hoʻohui mau i ka mahana a me ka hāmare wai no kahi ʻōnaehana palekana a lōʻihi.
