Papahana Manaʻo: ʻO ke kahawai ʻo Yangtze a hiki i Huaihe River Diversion Project
Ma ke ʻano he papahana mālama wai kī nui, ʻo ka Yangtze River a Huaihe River Diversion Project he papahana hoʻoheheʻe wai ma waena o nā kīwaha me nā hana nui o ke kaona a me ke kuaʻāina hoʻolako wai a me ka hoʻomohala ʻana i ka moku ʻo Yangtze-Huaihe River, i hui pū ʻia me ka irrigation. a me ka hoʻopiha wai a me ka hoʻomaikaʻi ʻana i ke kaiaola o Chaohu Lake a me Huaihe River. Mai ka hema a hiki i ka ʻākau, ua māhele ʻia i ʻekolu ʻāpana: ʻo Yangtze River a Chaohu, Yangtze-Huaihe River kamaʻilio, a me Yangtze River wai ma ka ʻākau. ʻO ka lōʻihi o ka laina hoʻoili wai he 723 mau kilomita, me 88.7 mau kilomita o nā kahawai hou, 311.6 mau kilomita o nā kahawai a me nā loko i kēia manawa, 215.6 mau kilomita o ka dredging a me ka hoʻonui ʻana, a me 107.1 mau kilomita o nā paipu kaomi.
Ma ka papa mua o ka papahana, ua hoʻolako ʻo Liancheng Group i nā pāpaʻi paʻi pālua nui a me nā paila kahe axial no nā ʻāpana he nui o ka muliwai ʻo Yangtze a i Huaihe River Diversion Project. Aia kēia papahana i ka māhele ʻelua o ka muliwai ʻo Yangtze a hiki i ka Papahana Hoʻololi muliwai ʻo Huaihe. Hoʻokumu ʻia ia ma ka pae mua o ka muliwai ʻo Yangtze a hiki i ka Huaihe River Diversion Project, e kālele ana i ka lako wai o ke kūlanakauhale a me ke kua'āina, i hui pū ʻia me ka irrigation a me ka hoʻopiha wai, e hana i nā kūlana no ka ʻāina e pane i nā pilikia palekana o ka wai a hoʻomaikaʻi i ke kaiaola. . Ua māhele ʻia i ʻelua mau ʻāpana nui: ka laina pahu wai a me ka lako wai iwi kuamoʻo. ʻO ke ʻano o ka pauma nui o ka pāhana lanakila, ʻo ia ka pāpaʻi pālua, e hāʻawi ana i nā ʻāpana wai a me nā lako ʻōnaehana kōkua hydraulic mechanical no Tongcheng Sanshui Plant, Daguantang a me Wushui Plant, a me Wanglou Station. E like me nā koi hoʻolako, ʻo 3 mau pāpaʻi pālua no Tongcheng Sanshui Plant ka pūʻulu mua o nā lako, a ʻo ke koena e hoʻolako mālie ʻia e like me nā koi.
ʻO nā koi hoʻohālikelike hana o ka pūʻulu wai mua i hoʻolako ʻia e Liancheng Group i Tongcheng Sanshui Plant penei:
Liancheng Solution: ʻO ka muliwai ʻo Yangtze a i Huaihe River Diversion Project
ʻO ka walaʻau a me ka haʻalulu maikaʻi
Hāʻawi mau ʻo Liancheng Group i nā huahana kiʻekiʻe a me nā hopena kūpono no ka muliwai Yangtze a i ka Huaihe River Diversion Project. He koʻikoʻi koʻikoʻi kēia papahana i nā hōʻailona ʻenehana o kēlā me kēia papahana o ka ʻāpana wai. Hoʻonui nā mea kūʻai aku i ka waiwai walaʻau, a ʻaʻole lākou e ʻae inā ʻaʻole hiki i 85 decibels. No ka pūʻulu wai, ʻoi aku ka nui o ka walaʻau o ke kaʻa ma mua o ka pā wai. No laila, i loko o kēia papahana, koi ʻia ka mea hana kaʻa e hoʻohana i kahi hoʻolālā hoʻohaʻahaʻa leo no ka mīkini kiʻekiʻe-voltage, a pono ia e hoʻokō i kahi hoʻāʻo ʻana i ka leo haʻahaʻa ma ka hale hana kaʻa. Ma hope o ka hoʻokō ʻia ʻana o ka walaʻau kaʻa, e hoʻouna ʻia i ka hale hana pamu.
Ua hoʻolālā ʻo Liancheng i nā ʻāpana paʻa i ʻoi aku ma mua o nā mea i manaʻo ʻia no nā papahana he nui, ʻoi aku hoʻi i nā ʻōlelo o ka vibration a me nā haʻalulu o nā wai wai. ʻO ka 500S67 o Tongcheng Sanshui Plant he 4-pae wikiwiki. Ua hoʻonohonoho ʻo Liancheng Group i nā lālā o ka hui papahana a me nā hui ʻenekinia e hoʻopaʻa i kahi hālāwai e kūkākūkā ai pehea e hōʻemi ai i ka walaʻau o ka pā wai, a ua hoʻokumu i kahi manaʻo a me ka hoʻolālā. I ka hopena, ua hoʻokō nā hōʻailona āpau o ka vibration a me ka walaʻau o ka pā wai i nā koi a hiki i ka pae kiʻekiʻe o ka honua. Hōʻike ʻia nā waiwai haʻalulu a me ka walaʻau ma ka papa aʻe:
Hoʻolālā hydraulic hoʻolālā kiʻekiʻe a mālama i ka ikehu
Ma keʻano o ka hoʻolālā hydraulic, ua koho nā limahana R&D i nā hiʻohiʻona hydraulic maikaʻi loa no ka hoʻolālā mua a hoʻohana i ka polokalamu 3D Solidworks no ka hoʻohālike. Ma o nā ʻano kiʻi kiʻi hoʻohālike kūpono, ua hōʻoia ʻia ka maʻalahi a me ka maʻalahi o nā ʻili o ke kahawai kahe o nā hiʻohiʻona paʻakikī e like me ke keʻena suction a me ke keʻena kaomi, a ua hōʻoia ʻia ka kūlike o ka 3D a me 2D i hoʻohana ʻia e CFD, a laila e hōʻemi i ka hewa hoʻolālā i loko. ka pae mua o ka R&D.
I ka wā R&D, ua nānā ʻia ka hana cavitation o ka pā wai, a ua nānā ʻia ka hana o kēlā me kēia wahi hana i koi ʻia e ka ʻaelike me ka hoʻohana ʻana i ka polokalamu CFD. I ka manawa like, ma ka hoʻomaikaʻi ʻana i nā ʻāpana geometric e like me ka impeller, volute a me ka ratio area, ua hoʻomaikaʻi maikaʻi ʻia ka pono o ka pā wai i kēlā me kēia wahi hana, i loaʻa i ka paila wai nā hiʻohiʻona o ka hana kiʻekiʻe, ākea ākea a kiʻekiʻe. ka pono a me ka mālama ikehu. Hōʻike nā hopena hoʻāʻo hope loa ua hōʻea nā hōʻailona āpau i ka pae kiʻekiʻe honua.
ʻO ka hale hilinaʻi a paʻa
I loko o kēia papahana, ʻo nā ʻāpana koʻikoʻi e like me ke kino pauma, impeller, a me ka pahu pahū i hoʻopaʻa ʻia i nā helu hōʻoia ikaika me ka hoʻohana ʻana i ke ʻano mea paʻa e hōʻoia ai ʻaʻole ʻoi aku ke koʻikoʻi o kēlā me kēia ʻāpana i ke koʻikoʻi i ʻae ʻia o ka mea. Hāʻawi kēia i kahi hōʻoia no ka maikaʻi palekana, hilinaʻi, a paʻa hoʻi o ka paila wai.
Nā hualoaʻa mua
No kēia papahana, ua hoʻomalu pono ʻo Liancheng Group i ka hana ʻana i ka mold, ka nānā ʻole ʻana, ka nānā ʻana i nā mea a me ka mālama ʻana i ka wela o ka pā wai mai ka hoʻomaka ʻana o ka papahana, ka hana ʻino a me ka maikaʻi, ka wili, ka hui ʻana, ka hoʻāʻo a me nā kikoʻī ʻē aʻe.
Ma ʻAukake 26, 2024, hele ka mea kūʻai aku i ka Liancheng Group Suzhou Industrial Park e ʻike i nā hōʻike hōʻike hōʻike hana o ka pā wai 500S67 o Tongcheng Sanshui Plant. ʻO nā hoʻāʻo kikoʻī e pili ana i ka hoʻāʻo ʻana i ka wai, ke kaulike rotor dynamic, ka hoʻāʻo cavitation, ka hoʻokō hana, ke piʻi ʻana o ka mahana, ka hoʻāʻo walaʻau, a me ka hoʻāʻo vibration.
Ua mālama ʻia ka hālāwai ʻae hope loa o ka papahana ma ʻAukake 28. Ma kēia hālāwai, ua ʻike nui ʻia nā hōʻailona hana o ka pā wai a me nā hana i hana ʻia e ka poʻe Liancheng e ka hui kūkulu hale a me Party A.
I ka wā e hiki mai ana, e hoʻoikaika mau ʻo Liancheng Group a hoʻomau i ka hāʻawi ʻana i nā hopena kūpono a me nā huahana kiʻekiʻe no nā papahana mālama wai.
