Noonoo Koho Pum FGD



ʻO ka flue gas desulfurization (FGD) kahi kaʻina e hiki ai ke hoʻokuʻu pono ʻia nā kinoea hoʻopau ʻia mai nā mea hoʻomohala i hoʻoiho ʻia i ka lewa. ʻO nā slurries FGD he ʻano abrasive, corrosive a me ka paʻa. No ka paʻi ʻana i nā slurries corrosive me ka hilinaʻi, pono e hoʻolālā ʻia ka paila no ka hana maʻemaʻe a me ka ʻoluʻolu. Pono e hana ʻia mai nā mea kūpono no ka slurry kikoʻī, i hui pū ʻia a uhi pono ʻia.

 

Moʻo o TL >Pum FGD he pae hoʻokahi ka hoʻoheheʻe ʻana i ka pauma centrifugal. Hoʻohana nui ʻia ia e like me ka circulation pump no ka hale kiaʻi absorbent i nā noi FGD. Loaʻa iā ia nā hiʻohiʻona: ākea ākea kahe kahe, kiʻekiʻe kiʻekiʻe, kiʻekiʻe mālama mana. Hoʻohālikelike ʻia kēia pūʻulu o ka pamu e ka paʻa paʻa X bracket hiki ke mālama i ka nui o ka nui. I kēia manawa, hoʻomohala kā mākou hui i nā ʻano mea he nui i kuhikuhi ʻia ma nā pamu no FGD.

 

Loaʻa i ka waiwai maikaʻi loa

I mea e pale aku ai i ka wā hoʻomaha i hoʻolālā ʻole ʻia, pono e hoʻomaopopo a hoʻoponopono ʻia nā wahi nāwaliwali. ʻO nā wahi e noʻonoʻo ai no nā slurries corrosive, ʻo ia nā sila shaft, nā komo ʻana o ka uwea a me ka hoʻoilo.

Pum TL FGD

Ma na helu

No. 1, he maka silicon carbide mechanical sila. Ua hōʻike ʻia ka hoʻāʻo ʻana he 15-20 mau manawa ʻoi aku ka lōʻihi o ka silicon carbide shaft sila ma mua o ka carbon ceramic a me 2.5-3 mau manawa ʻoi aku ka lōʻihi ma mua o ka tungsten carbide. Pono e palahalaha nā maka sila - (he huaʻōlelo pili, akā ʻoi aku ka maikaʻi o ka palahalaha) - e kāpae i nā ʻāpana maikaʻi; pono e hoʻokaʻawale ʻia ka pūnāwai e hoʻopili ai i kēia mau maka mai ka slurry.

 

ʻO ka helu 2, pono e hoʻopaʻa ʻia ke komo ʻana o ke kaula i ke keʻena kaʻa no ka mālama pono ʻana i ke kaʻa i ka wā e komo ai ka makū mai luna mai, a pono e hāʻawi i kahi ʻano hana hoʻoikaika kino. Wehe ʻia nā alakaʻi hoʻokahi i ka uea ʻole a hele i loko o kahi pale epoxy e pale ai i ka makū o ke kaula pohō mai ke komo ʻana i ke keʻena stator. Hāʻawi kahi poloka hoʻokaʻawale i kahi pale hou a ua hoʻopaʻa ʻia ʻo O-ring. Hiki ke hoʻohana ʻia kēia papa e hoʻomaʻamaʻa i nā ʻano like ʻole o ke kahua.

 

ʻO ka helu 3, ma ke ʻano laulā, hiki ke hoʻoheheʻe ʻia ka wela ma o ka hale kaʻa kaʻa a hiki i ka mīkini paʻi. Pono e hoʻohana ʻia kahi ala e hoʻopau mau ai i ka wela generator ma o ka mea hoʻololi wela - ʻoiai ʻo ka gypsum a i ʻole nā ​​​​mea ʻē aʻe ke kumu o ke kūkulu ʻana. Pono e hoʻohana ʻia ke ʻano hoʻoluʻu 24/7 i ka ukana piha.

 

ʻO nā ʻano hana hoʻoluʻu kūloko kūloko e ʻae ai i ka paila ʻana i kahi pae wai haʻahaʻa i loko o ka puʻu, no laila e hoʻonui ai i ka hiki ʻana o ka sump; hiki iā ia ke unuhi i loko o nā haneli mau galani o ka nui o ka wai.

 

ʻO ka helu 4, pono ka pale pale i nā hiʻohiʻona adhesion kiʻekiʻe ma muli o ka hana hydraulic i ka sump. Hiki ke hoʻopau mua ʻia nā uhi hoʻopili haʻahaʻa. (Adhesion i ana i Newtons per square millimeters (N/mm2).) No ka laʻana, maʻamau ʻoihana pena pena i ka adhesion pae o ma kahi o 4 N/mm2, oiai elua-hui me ka kiʻekiʻe pakeneka o ka paʻa i ka adhesion pae o. ma kahi o 7 N/mm2. I kēia mau lā, loaʻa i ka 15 N/mm2 ka hoʻopaʻa ʻana o nā uhi seramika wai. ʻO nā haku mele elastomeric e kūʻē i ka ʻino a me nā seramika impregnated e pale i ka ʻaʻahu.

 

Helu 5, mea paʻakikī chrome kiʻekiʻe (i 650 me BHN; Rockwell “C” ʻO ka pālākiō o 63) pono e hoʻolako ʻia inā ʻo ka abrasion ke kumu nui. I nā hihia kahi e hopohopo nui ai ka corrosion, pono e hoʻohana ʻia nā Duplex Stainless Steels e like me CD4MCU.

 

Inā makemake ʻoe e ʻike hou aku e pili ana i ka >ʻO ka pauma FGD maikaʻi loa, hoʻokipa iā >kāhea iā mā˚ou i kēia lā a i ʻole e noi i kahi ʻōlelo.

Kaʻana like

Aʻe:

Nūhou hou loa

Inā makemake ʻoe i kā mākou huahana, hiki iā ʻoe ke koho e waiho i kāu ʻike ma aneʻi, a e hoʻopili koke mākou iā ʻoe.


E kaomi i ke komo no ka huli ʻana a i ʻole ESC e pani
