    1. He aha ka Pipe Penstock?

    No nā lako kūikawā ʻo Penstock Pipe, a e like me ka wehewehe ʻana o ka "Regulations on Safety Supervision of Special Equipment", pili lākou i nā lako tubular e hoʻohana ana i kekahi kaomi e lawe i ke kinoea a i ʻole ka wai. Ua wehewehe ʻia ka laulā e like me ke kinoea, ke kinoea hoʻoheheʻe ʻia, ka mīkini mahu me ke kaomi hana kiʻekiʻe loa ma mua o a i ʻole like me 0.1MPa (gauge pressure), a i ʻole flammable, explosive, toxic, corrosive liquid medium me ka wela o ka hana kiʻekiʻe ma mua a i like paha me ka. wahi paila maʻamau, a me nā paipu me ke anawaena inoa i ʻoi aku ma mua o 25mm.

    Ke kumu hana:

    No ka Pipe Penstock hoʻokahi, hilinaʻi ʻo ia i ka mana o waho a i ʻole ka ikaika hoʻokele o ka mea ʻenehana ponoʻī e lawe i ke kikowaena mai ke kumu o ka pipeline kaomi a hiki i ka hopena o ka pipeline kaomi.

    ʻO nā hiʻohiʻona o Penstock Pipe:

    ʻO Penstock Pipe kahi ʻōnaehana pili a pili kekahi i kekahi, huki a hoʻoneʻe i ke kino holoʻokoʻa.

    Loaʻa i nā paipu kaomi kahi ratio nui a hiki i ka paʻa ʻole, e hopena i nā kūlana koʻikoʻi paʻakikī ma mua o nā moku kaomi.

    He paʻakikī ke kahe o ka wai i nā pipelines, me ka liʻiliʻi o ka hoʻololi ʻana i nā kūlana hana ma mua o nā moku kaomi (e like me ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, displacement deformation, makani, hau, ōlaʻi, etc.).

    Aia nā ʻano like ʻole o nā ʻāpana pipeline a me nā ʻāpana kākoʻo pipeline, kēlā me kēia me kona ʻano ponoʻī a me nā koi ʻenehana kikoʻī, a paʻakikī ke koho ʻana i nā mea.

    ʻOi aku ka nui o nā wahi leakage ma ka pipeline ma mua o ka moku kaomi, a he ʻelima mau helu no ka valve hoʻokahi.
    Nui nā ʻano a me ka nui o nā pipeline kaomi, a he nui nā loulou i ka hoʻolālā, hana ʻana, hoʻonohonoho, nānā ʻana, a me ka hoʻokele noiʻi, he ʻokoʻa loa ia mai nā moku kaomi.

    Ke kumu o Penstock Pipe:

    Kaʻa lawe (kumu nui)
    Hana mālama (no nā paipu lōʻihi)
    Hoʻololi wela (no nā paipu ʻoihana)

    Nā ʻanuʻu hoʻolālā no ka Pipe Penstock:

    E koho i nā mea pipeline e pili ana i ke ʻano o ka waena, ke kaomi, a me ka mahana.
    E helu i ke anawaena paipu a me ka mānoanoa o ka paia, a ho'omākaukau a ho'oholo paha i ka papa paipu.
    E hoʻomohala i nā hoʻolālā hoʻolālā pipeline, e hoʻoholo i ke ala ʻana o ka pipeline, a me nā ʻano kau.
    E kaha i ka hoʻolālā pipeline a me ka ʻaoʻao ʻaoʻao axial.
    E hoʻomohala i kahi papa ʻano pipeline.
    Hana i ke koʻikoʻi, ka uku wela, a me ke kākoʻo ʻana i ka helu ʻana.
    Hāʻawi i nā mea ʻenehana kivila i nā mea nui e pili ana.
    Hoʻopiha i nā kiʻi hoʻolālā a me ke kaha kiʻi pūlima.
    2. Nā pilikia i ka hoʻolālā hoʻolālā o nā paipu kaomi
    Aia kekahi mau ʻike kikoʻī ma nā ʻanuʻu hoʻolālā āu e makemake ai e hoʻomaopopo?

    E ho'āʻo e hoʻohana i ka hoʻolālā hanger e hana i ka pipeline i kahi kokoke loa i nā hale a me nā hale e kū nei, akā e pale i nā mea maʻalahi me nā ukana nui.

    ʻAʻole pono e hoʻonohonoho ʻia nā paipu i loko o ke ʻano o ke kūkulu ʻana i nā lua hoʻokiʻekiʻe, nā mea hana i nā wahi e ʻoki ai i nā ʻāpana o loko, a me nā wahi hoʻopau flange.

    Pono e hoʻonohonoho ʻia ka hoʻolālā pipeline ma nā lālani like, me nā laina pololei a me nā liʻiliʻi liʻiliʻi a me nā kikowaena e like me ka hiki. Hiki i kēia ke hoʻemi i ka nui o nā paipu paipu, mālama i nā mea waiwai, a nani a maʻalahi hoʻi e hoʻokomo.

    Pono e hoʻonohonoho ʻia nā paipu i nā lālani e like me ka hiki, a ʻo ka lalo o nā paipu ʻole e hoʻopili ʻia me ka lepo o ke kākoʻo paipu e hoʻomaʻamaʻa i ka hoʻolālā ʻana o ke kākoʻo.

    Ke hoʻololi ke kiʻekiʻe a i ʻole ke kuhikuhi o ka pipeline, pono ia e pale i ka hoʻokumu ʻana o nā "ʻeke" o ke kinoea i hōʻiliʻili ʻia a i ʻole ka wai i loko o ka pipeline. Inā ʻaʻole hiki ke pale ʻia kēia, pono e hoʻokomo ʻia nā kiwi hoʻopau ma nā wahi kiʻekiʻe a pono e hoʻokomo ʻia nā kiwi hoʻokuʻu wai ma nā wahi haʻahaʻa.

    ʻO ka hoʻomoe ʻana o ka paipu e loaʻa i kahi pali, a ʻo ka ʻaoʻao o ka slope ma ke ʻano like me ka ʻaoʻao kahe o nā mea, akā aia kekahi mau ʻokoʻa, e hoʻoholo ʻia e like me ke kaʻina hana.

    ʻAʻole pono e hoʻolako ʻia nā paipu ma luna o nā alanui a me nā kaʻaahi me nā ʻāpana hiki ke kahe, e like me nā flanges, nā hui kaula, nā compensators me nā mea hoʻopihapiha, etc.

    I ka hoʻohui ʻana i kahi paipu lālā mai kahi paipu nui kinoea, pono e hoʻopili ʻia mai luna o ka paipu nui.

    No ka hoʻonohonoho ʻana o nā paipu hui like ʻole, nā paipu kinoea, nā paipu wela, nā paipu pono, a me nā pahu mea uila e waiho ʻia ma ka papa luna, ʻoiai ʻo nā pipeline corrosive medium a me nā pipeline haʻahaʻa haʻahaʻa e kau ʻia ma ka papa haʻahaʻa.

    ʻAʻole pono e waiho ʻia nā mea hiki ke ahi, pahū, ʻona, a me nā mea ʻino i loko o nā lumi noho, nā alapiʻi, nā alahele, a me nā wahi ʻē aʻe. Pono e alakaʻi ʻia ka paipu puka i kahi i koho ʻia i waho a i ʻole 2m ma luna o ka hale.

    ʻAʻole pono nā paipu me ka ʻole o ka insulation i ke kākoʻo paipu a i ʻole ke kākoʻo. Pono e kākoʻo ʻia nā paipu ʻole a me nā paipu me nā ʻāpana hoʻokaʻawale nui e nā pale paipu a i ʻole ke kākoʻo.

    ʻO nā kūlana no ke kanu pololei ʻana i nā paipu:

    ◇ ʻAʻole hiki ke hoʻomoe ʻia ma ka honua nā paipu e lawe ana i nā mea ʻawaʻawa, ʻaʻohe ʻino, a me nā mea pahū ʻole ma muli o kekahi mau kumu.
    ◇ E hana i nā laina paipu waena e pili ana i nā pahu mālama lalo a i ʻole nā ​​keʻena pauma lalo.
    ◇ ʻO ka wai hoʻoluʻu a me ka wai ahi a i ʻole nā ​​paipu ahi pahu.
    ◇ ʻO nā paipu hoʻomehana me ka mahana hana ma lalo o 150 ℃.

    3. Nā loina no ke koho ʻana i nā mea paipu maʻamau no nā paipu kaomi?

    Hoʻoholo ʻia ka hoʻohana ʻana i nā mea paipu maʻamau no nā pipeline kaomi e nā kūlana hana o ka mea e lawe ʻia ana (e like me ke kaomi, ka mahana) a me nā ʻano o ka medium ma lalo o kēia mau kūlana. E noʻonoʻo i kēia mau mea:

    Nā mea paipu i makemake ʻia:

    Ke koho ʻana i nā mea paipu, manaʻo mua ʻia nā mea metala. Ke kūpono ʻole nā ​​mea metala, noʻonoʻo ʻia nā mea metala ʻole. Pono e hāʻawi mua ʻia i ke koho ʻana i nā paipu kila no nā mea metala, a ma hope o nā mea metala non-ferrous. I nā paipu kila, pono e noʻonoʻo mua ʻia ke kila kalapona, a pono ke hoʻohana ʻia ke kila kila inā ʻaʻole pili. I ka noʻonoʻo ʻana i nā mea hao kalapona, pono e noʻonoʻo mua ʻia nā paipu kila welded, a pono ke koho ʻia nā paipu kila ʻole inā ʻaʻole pili.

    ʻO ka mana o ke kaomi waena:

    》 ʻO ke kiʻekiʻe o ke kaomi o ka mea lawe, ʻoi aku ka mānoanoa o ka paia o ka paipu, a ʻoi aku ka kiʻekiʻe o nā koi no ka mea paipu maʻamau.

    ʻAʻole kūʻokoʻa ka medium a ʻaʻole pono i nā koi waiwai kiʻekiʻe. Hiki ke hoʻohana ʻia nā paipu kila kalapona maʻamau.
    Inā he ʻakika a alkaline paha ka waena, pono e koho i nā paipu kūpaʻa ʻakika a alkali.
    Hoʻohana ʻia nā paipu i hana ʻia me ke kila kalapona no ka lawe ʻana i ka wai a me ka mahu.

    Ka hopena o ka hana o ka paipu iho:

    Ma waho aʻe o ka hana o ka lawe ʻana i ka medium, aia kekahi mau paipu i ka hana o ka haʻalulu haʻalulu, ka hoʻonui ʻana i ka wela, a hiki ke neʻe pinepine ma lalo o nā kūlana hana.

    Ka hopena o ka hāʻule kaomi:

    Ma hope o ke koho mua ʻana o ka mea paipu, pono pū ka helu ʻana i ka hāʻule o ke kaomi paipu e hoʻoholo ai i ke anawaena o loko o ka paipu. E helu i ka hāʻule paʻi e ʻike inā kūpono ka mea i koho ʻia i nā koi. ʻOi aku ka maikaʻi i ke koho mua ʻana i nā paipu plastik, he mea nui e nānā hou aku i ka loiloi o ka hāʻule ʻana o ke kaomi.

    4. Nā loina no ke koho ʻana i nā mea paipu kila maʻamau no nā paipu kaomi

    He aha nā loina no ke koho ʻana i nā mea paipu maʻamau no nā paipu kaomi? I kēia lā, e kamaʻilio ka luna hoʻoponopono no kēia mea.

    (1) Nā Mea Paipu Koho ʻia
    Ke koho ʻana i nā mea paipu, manaʻo mua ʻia nā mea metala. Ke kūpono ʻole nā ​​mea metala, noʻonoʻo ʻia nā mea metala ʻole. ʻOi aku ka maikaʻi o nā paipu kila no nā mea metala, a ma hope o nā mea metala non-ferrous. I nā paipu kila, pono e noʻonoʻo mua ʻia ke kila kalapona, a pono ke hoʻohana ʻia ke kila kila inā ʻaʻole pili. I ka noʻonoʻo ʻana i nā mea hao kalapona, pono e noʻonoʻo mua ʻia nā paipu kila welded, a pono ke koho ʻia nā paipu kila ʻole inā ʻaʻole pili.
    (2) Ka mana o ke kaomi waena
    ʻO ke kiʻekiʻe o ke kaomi o ka mea lawe, ʻoi aku ka mānoanoa o ka pā o ka paipu, a ʻoi aku ka kiʻekiʻe o nā koi no ka mea paipu maʻamau.
    Ke piʻi ke kaomi waena ma luna o 1.6MPa, hiki ke koho ʻia nā paipu kila ʻole a i ʻole nā ​​paipu metala non-ferrous. Ke kiʻekiʻe loa ka puʻe, e like me ka hana ʻana i ka ammonia synthetic, urea, a me ka methanol, ua koho ʻia kekahi mau paipu i ke kaomi maʻamau a hiki i 32MPa, a ua koho ʻia nā paipu kila maʻemaʻe kiʻekiʻe me nā mea o 20 # a i ʻole 15CrMo. Hoʻohana pinepine ʻia nā paipu keleawe a me ke keleawe no nā paipu ma nā mea ʻawaʻawa a me nā paipu oxygen me ke kaomi ʻoi aku ma mua o 10MPa.
    Ke emi iho ke kaomi ma lalo o 1.6MPa, hiki ke noʻonoʻo ʻia nā paipu kila welded, ka paipu hao a i ʻole nā ​​paipu non-metallic. Eia nō naʻe, ʻaʻole ʻoi aku ka nui o ke kaomi o ka mea i lawe ʻia e ka paipu hao ma mua o 1.0MPa. ʻO ke kaomi maʻamau i hiki i nā paipu non-metallic ke kūpaʻa e pili ana i nā ʻano mea like ʻole, e like me nā paipu polyvinyl chloride paʻakikī, me ke kaomi lawelawe ma lalo a i ʻole like me 1.6MPa; ʻO nā paipu polypropylene i hoʻoikaika ʻia me ke kaomi lawelawe ma lalo o a i ʻole like me 1.0MPa; ʻO nā paipu ABS, me ke kaomi hana ma lalo a i ʻole like me 0.6MPa.
    No nā paipu wai, i ka wā i emi ai ke kaomi wai ma lalo o 1.0MPa, hoʻohana mau ʻia nā paipu kila welded i hana ʻia me Q235A; Ke ʻoi aku ka nui o ke kaomi o ka wai ma mua o 2.5MPa, hoʻohana maʻamau ʻo 20 # paipu kila ʻole.
    (3) Ka hopena o ka wela waena
    ʻO nā paipu i hana ʻia i nā mea like ʻole e kūpono i nā pae wela like ʻole. Ke emi ka mahana o ke kinoea hydrogen ma lalo o 350 ℃, 20 # mau paipu kila ʻole e hoʻohana ʻia no ke kinoea hydrogen me ke kaomi o 1.0MPa. Aia ka mahana o ke kinoea hydrogen i loko o ka laulā o 351-400 ℃, 15CrMo a i ʻole 12CrMo nā paipu kila ʻole.
    (4) Ka hopena o nā waiwai kemika waena
    E lawe i nā pāpaho like ʻole me nā paipu like ʻole. ʻAʻole kūʻokoʻa kekahi mau media a ʻaʻole koi i nā koi waiwai kiʻekiʻe. Hiki ke hoʻohana i nā paipu kila kalapona maʻamau; He ʻakika a alkaline paha kekahi media, no laila pono e koho i nā paipu kūpaʻa ʻakika a alkali. ʻOkoʻa nā koi no ka hoʻohana ʻana i nā paipu ma waena o nā waikawa ikaika a nāwaliwali a me nā kumu. ʻO ka waikawa like a i ʻole ka base, me nā ʻokoʻa like ʻole, loaʻa nā koi like ʻole no ka mea o nā paipu. Inā lawe ʻia ka wai a me ka mahu, ua lawa nā paipu i hana ʻia me ke kila kalapona. I nā mea kanu urea, hoʻohana mau ʻia nā paipu kila kila no ka lawe ʻana i ka carbon dioxide, no ka mea, hoʻokumu ʻia ka carbon dioxide i carbon dioxide i ka wā e hālāwai ai me ka wai, a he hopena ʻino i nā paipu kila maʻamau. Inā hana ʻia ka ʻakika sulfuric, hiki ke hoʻohana ʻia nā paipu kila kalapona, ʻoiai no ka dilute sulfuric acid, ʻaʻole hiki ke hoʻohana ʻia nā paipu kila kalapona no ka mea hiki i ka dilute sulfuric acid a me ke kila kalapona ke hana kemika a hoʻopau i ke kila kalapona. No laila, hiki ke hoʻohana ʻia nā paipu alumini paʻakikī.
    (5) Ka hopena o ka hana o ka paipu pono'ī
    Ma kahi o ka hana o ka lawe ʻana i ka medium, aia kekahi mau paipu i ka hana o ka haʻalulu haʻalulu a me ka coefficient o ka hoʻonui wela. Ma lalo o nā kūlana hana, hiki iā lākou ke neʻe pinepine, e like me ka liquefied petroleum gas, oxygen a me ka acetylene gas no ka hoʻohana kīwila ma ke kūlana hoʻopiha piha. Hoʻohana pinepine ʻia nā paipu kila kila kiʻekiʻe i ulana ʻia no nā paipu, ma kahi o nā paipu kila paʻakikī i hiki ʻole ke neʻe.
    (6) Ka hopena o ka hāʻule kaomi
    Ma hope o ke koho mua ʻana o ka mea paipu, pono pū ka helu ʻana i ka hāʻule o ke kaomi paipu e hoʻoholo ai i ke anawaena o loko o ka paipu. E helu i ka hāʻule paʻi e ʻike inā kūpono ka mea i koho ʻia i nā koi. ʻOi aku ka maikaʻi i ke koho mua ʻana i nā paipu plastik, he mea nui e nānā hou aku i ka loiloi o ka hāʻule ʻana o ke kaomi.
    No ka helu ʻana i ka pipeline kaomi, i ka hoʻolālā ʻenekinia, ʻo ke koena waiwai, ke kaulike o ka ikehu a me ka helu ʻana i nā mea hana e hana maʻamau e like me ka pae hana e hoʻoholo mua i ka kahe waiwai. E pili ana i ka ʻikepili pili, e noʻonoʻo i kahi kahe kahe waiwai, e helu i ke anawaena o loko o ka paipu, e nānā i ka manual a i ʻole ka maʻamau, a koho i ka paipu maʻamau. ʻO ke anawaena o loko o ka paipu maʻamau i koho pinepine ʻia e like a ʻoi aku paha ka nui ma mua o ke anawaena o loko i helu ʻia. E helu hou i ke kaomi o ka paipu.
