HGL a me HGW moʻo kū hoʻokahi pae a mehoʻokahi pae kiʻekiʻe kimemikaua hoʻokumu ʻia ma luna o nā pamu kemika kumu o kā mākou hui. Noʻonoʻo piha mākou i ka ʻokoʻa o nā koi hoʻolālā o nā pamu kemika i ka wā e hoʻohana ai, e kiʻi i ka ʻike hoʻomohala holomua ma ka home a ma waho, a hoʻohana i nā pamu kaʻawale. shaft, kahi hoʻopili hoʻopili ʻana, nona nā hiʻohiʻona o ke ʻano maʻalahi loa, concentricity kiʻekiʻe, haʻalulu liʻiliʻi, hoʻohana pono, a me ka mālama pono. He hanauna hou ia o ka pauma kemika hoʻokahi pae i hoʻomohala ʻia.
Palapala noi
HGL a me HGW moʻo kemika paumaHiki ke hoʻohana ʻia i kekahi ʻano i ka ʻoihana kemika, ka lawe ʻana i ka aila, ka meaʻai, ka mea inu, ka lāʻau lapaʻau, ka mālama ʻana i ka wai, ka mālama ʻana i ke kaiapuni a me kekahi mau waikawa, alkali, paʻakai a me nā noi ʻē aʻe e like me nā kūlana hoʻohana kikoʻī o ka mea hoʻohana. ʻO kahi ʻano mea ʻino, ʻaʻohe ʻāpana paʻa a i ʻole ka liʻiliʻi o nā ʻāpana, a he viscosity like me ka wai. ʻAʻole ʻōlelo ʻia no ka hoʻohana ʻana i nā mea ʻawaʻawa, pahū, pahū, a i ʻole nā mea ʻino loa.
(1) Nitric acid a me nā noi i loko o ka ʻoihana nitric acid
I ke kaʻina hana o ka nitric acid e ka ammonia oxidation, ka dilute nitric acid (50-60%) i hana ʻia i loko o ka hale kiaʻi absorption stainless steel e kahe mai ka lalo o ka hale kiaʻi i loko o ka pahu mālama kila kila, a lawe ʻia i ke kaʻina hana aʻe. me ka pauma kila kila. E noʻonoʻo i ka wela waena a me ke kaomi inlet maanei.
(2) Nā noi i ka phosphoric acid a me ka phosphoric acid ʻoihana
No ka ʻakika maʻemaʻe, ʻo Cr13 ke kila kuhiliʻole ke kūpaʻa wale i ka aerated dilute acid, a me ka chromium-nickel (Cr19Ni10) austenitic stainless steel ke kūʻē wale i ka aerated dilute acid. ʻO ka mea maikaʻi loa ka phosphoric acid-resistant material he chromium-nickel-molybdenum (ZG07Cr19Ni11Mo2) stainless steel, etc.
Eia nō naʻe, no ke kaʻina hana phosphoric acid, ʻoi aku ka paʻakikī o ke koho ʻana i nā mea o ka paila ma muli o nā pilikia corrosion i hoʻokumu ʻia e ka hele ʻana o nā haumia i ka waikawa phosphoric, a pono e mālama ʻia me ka makaʻala.
(3) Hoʻohana i ka sodium chloride a me ka ʻoihana paʻakai (ka wai brine, ka wai kai, a me nā mea ʻē aʻe)
ʻO ke kila kila Chromium-nickel he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e kūʻē i nā ʻoluʻolu sodium chloride neutral a me ka liʻiliʻi alkaline, ka wai kai a me ka wai paʻakai ma kahi mahana a me ka noʻonoʻo, a hoʻohana nui ʻia. Eia nō naʻe, pono e hoʻomaopopo ʻia e hiki mai ana ka corrosion kūloko weliweli i kekahi mau hihia.
ʻO nā paila kila kilahoʻohana nui ʻia i ka ʻoihana meaʻai no ka mālama ʻana i ka brine a me ka meaʻai paʻakai. Eia nō naʻe, pono e uku ʻia i nā pilikia crystallization media a me nā pilikia koho seal mechanical.
(4) Hoʻohana i ka sodium hydroxide a me ka ʻoihana alkali
Hiki i ka Chromium-nickel austenitic stainless steel ke kū i ka sodium hydroxide ma lalo o 40-50% a hiki i 80 ° C, akā ʻaʻole ia e kū i ka wai alkali kiʻekiʻe a me ka wela wela.
He kūpono wale ke kila kila Chromium no ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa alkali.
Pono e nānā i ka pilikia o ka crystallization waena.
(5) Ke noi ma ka lawe ʻana i ka aila
Pono e noʻonoʻo ʻia i ka viscosity o ka waena, ke koho ʻana i nā ʻāpana ʻāpana, a inā paha he koi pahū ka pahu, etc.
(6) Ke noi ma ka ʻoihana lāʻau lapaʻau
Hiki ke hoʻokaʻawale ʻia nā paila lapaʻau i ʻelua mau ʻāpana e like me ke ʻano o ka lawe ʻana o ka pama.
ʻO kekahi ʻano ʻo ia ka pauma wai maʻamau, nā ʻōpala wai wela a me nā ʻōnaehana mālama wai ʻino i hoʻohana ʻia i nā papahana lehulehu, a ʻo kekahi ʻano ʻano he pamu no ka lawe ʻana i nā media kaʻina hana e like me nā wai kemika, waena, wai maʻemaʻe, nā waikawa a me nā alkalis.
He haʻahaʻa ko ka mua no nā pamu a hiki ke mālama ʻia e nā pamu i hoʻohana ʻia i nā mea hana kemika maʻamau, aʻo ka mea hope he mau koi kiʻekiʻe no nā pamu. Pono nā paila e hoʻokō i nā koi ʻenehana no nā pamu centrifugal i hoʻohana ʻia i nā mea lapaʻau.
(7) Hoʻohana i ka ʻoihana meaʻai a me ka mea inu
I loko o ka ʻoihana meaʻai a me ka mea inu, ʻaʻole hiki ke hoʻopōʻino a nāwaliwali paha ka medium, akā ʻaʻole ʻae ʻia ka ʻōpala, a kiʻekiʻe loa ka maʻemaʻe o ka medium. I kēia hihia, hiki ke hoʻohana ʻia kahi paila kila kila.
Nā hiʻohiʻona hale
1. ʻO ka hoʻolālā ʻāpana ʻana o ke kumu pāpaʻi o kēia pūʻulu o nā paila e pale pono i ka pōʻino ʻino i ke kumu kaʻa. Hoʻopaʻa loa kēia i ka hana paʻa a hilinaʻi lōʻihi o ka kaʻa.
2. ʻO kēia pūʻulu o nā pāpaʻi he mea hilinaʻi a noʻonoʻo hoʻi ka hoʻoheheʻe ʻia ʻana o ka lāʻau paila. Hiki ke hoʻohana maʻalahi ka pāpaʻi kūpaʻa i ka mīkini maʻamau B5 structure no ka hoʻokele pololei ʻana i ka pā wai, a hiki i ka ʻōpala hoʻoneʻe ke hoʻohana maʻalahi i ka mīkini maʻamau B35 structure e hoʻokele pololei i ka pā wai.
3. Hoʻolālā ʻia ka uhi pāpaʻi a me ka bracket o kēia pūʻulu o nā pumps e like me ʻelua mau ʻāpana kūʻokoʻa me ke ʻano kūpono.
4. ʻO kēia pūʻulu o nā pumps he hale maʻalahi loa a maʻalahi ka mālama. I ka manawa e pono ai ke hoʻololi ʻia ka pahu pāpaʻi, ua maʻalahi ka wehe ʻana a hoʻokomo, a pololei a hilinaʻi ke kūlana.
5. Hoʻopili paʻa ʻia ka lāʻau pahū a me ke kumu kaʻa o kēia moʻo e kahi hoʻohui i hoʻopili ʻia. ʻO ka ʻenehana holomua a kūpono hoʻi a me ka ʻenehana hui e hana ai i ka shaft pump i kiʻekiʻe concentricity, haʻahaʻa haʻahaʻa a me ka leo haʻahaʻa.
6. Hoʻohālikelike ʻia mepāpaʻi kimeki paeo ka hale maʻamau, he ʻano paʻa ko kēia pūʻulu o nā pāpaʻi paepae a ua hoʻemi nui ʻia ka papahele o ka ʻāpana.
7. Hoʻohana kēia pūʻulu o nā paila i ka hoʻolālā hiʻohiʻona hydraulic maikaʻi loa. Paʻa a maikaʻi ka hana o ka paila.
8. ʻO ke kino o ka paila, ka uhi pahū, ka impeller a me nā ʻāpana ʻē aʻe o kēia pūʻulu o nā pumps i hoʻolei pololei ʻia e ka hoʻolei kālā, me ka pololei kiʻekiʻe kiʻekiʻe, nā kahawai kahe a me nā hiʻohiʻona nani.
9. ʻO nā uhi pāpaʻi, nā kumu, nā brackets a me nā ʻāpana ʻē aʻe o kēia pūʻulu pumps e hoʻohana i nā hoʻolālā āpau a hiki ke loli.
