DT moʻo desulphurization pauma
Nānā Hana Hana:
Hoʻohana nā ʻāpana hoʻopaʻa paʻa i ka ʻenehana simulation holomua e hōʻoiaʻiʻo i ka hoʻolālā paʻa hilinaʻi a me ka hana kiʻekiʻe.
Ua hōʻoia ʻia nā mea hoʻoheheʻe anti-corrosion & anti-wear a me nā mea hao i kūkulu pono ʻia no nā pamu FGD e ka hana e hiki ai iā lākou ke hōʻoia i ka hana ʻana o ka pauma lōʻihi. Ma o ka hoʻoponopono ʻana i nā ʻāpana bearing e hoʻololi i ke kūlana impeller i loko o ke keʻena pamu i nā manawa āpau hiki ke hoʻokō i ka hana kiʻekiʻe o ka pamu. Hōʻike ʻia ka paila e ke ʻano kuʻi hope i maʻalahi a holomua.
He maʻalahi ka mālama a hoʻoponopono ʻana a pono ia e wehe i nā paipu wai inlet a me waho. Hoʻohana kūikawā ʻia ka pahu mechanical seal no ke kaʻina desulphurization a hilinaʻi kāna hana
Nā mea nui:
a) Hoʻohana nā ʻāpana pulu i ka loiloi simulation kahe kiʻekiʻe i ke kaʻina hana e hōʻoiaʻiʻo i ka hana hilinaʻi, kiʻekiʻe kiʻekiʻe o nā pamu. Hiki i ka mea kūʻai ke hana i ka pauma e holo mau i kahi kūlana hana maikaʻi ma o ka hoʻoponopono ʻana i nā mea lawe i loko o ka impeller pump e kūpono i ke kūlana o ka lua o ka pamu.
b) Hoʻolālā ʻia nā paila me ka ʻōnaehana hoʻonohonoho hope. Hōʻike ʻia lākou e ka hoʻolālā maʻalahi a maʻalahi ke hoʻoponopono ʻole me ka wehe ʻole ʻana i ka paipu inlet a me waho o ka paila. Hoʻohana ka hopena hope i nā bearings roll tapered i lawe ʻia mai a hoʻohana ka hopena hoʻokele i ʻelua bearings roller cylindrical me ka lubrication aila lahilahi. Hiki iā ia ke paipai i nā bearing?? kūlana hana e hoʻolōʻihi i ke ola lawelawe o nā bearings.
c) Hoʻolālā ʻia ka sila mīkini e like me ke ʻano o ke ʻano o ka pauma desulphurization, ʻano slurry a me ke ʻano noi. He sila mechanical pahu pahu. He hana maikaʻi, ola lōʻihi.
d) Hana ʻia nā mea hana FGD (Flue Gas Desulfurization) o ka paila i kahi ʻano mea hou Cr30 duplex stainless keʻokeʻo hao i hoʻomohala kūikawā ʻia e kā mākou hui ponoʻī. Loaʻa i ka mea hou ka hana nui i ka corrosion-resistant a me ka ʻaʻahu. ʻO ka paila, ka uhi pahū a me nā papa splice nā ʻāpana kaomi a hana ʻia me ka ductile cast iron. Hana ʻia ka impeller a me ka uhi hoʻoheheʻe ʻana i ka hao keʻokeʻo keʻokeʻo pālua Cr30. ʻO ka mea o ka uhi pā liner, frame plate liner, a me ka liner hope he ʻōpala maoli me ka hana abrasion maikaʻi maoli, māmā ke kaumaha, haʻahaʻa ke kumu kūʻai.
Nā hoʻohana nui:
Hoʻohana nui ia i loko o ka mana mea kanu no ka absorption tower circulation pump e hoʻouna i ka corrosive slurry.Power mea kanu, mea kanu kila no ka flue kinoea desulphurization.
