Ke kuleana, nā hiʻohiʻona, a me nā hoʻohana ʻana o Polarographic Dissolved Oxygen Sensors

Kumu Hana

Hoʻohana ʻia nā mea ʻike oxygen dissolved polarographic e pili ana i nā loina electrochemical, me ka hoʻohana mua ʻana i ka electrode Clark. Aia ka mea ʻike i kahi cathode gula, kahi anode kālā, a me kahi electrolyte kikoʻī, i hoʻopili ʻia e ka membrane permeable koho.

I ka wā o ke ana, hoʻoheheʻe ʻia ka oxygen ma o ka membrane i loko o ka mea ʻike. Ma ka cathode (electrode gula), hoʻemi ʻia ka oxygen, ʻoiai ma ka anode (electrode kālā), hiki ke oxidation. Hoʻopuka kēia kaʻina hana i ka diffusion o kēia manawa e like me ka neʻe ʻana o ka oxygen i hoʻoheheʻe ʻia i loko o ka hāpana, e hiki ai ke ana pololei.

Nā mea nui

Hoʻohana nui ʻia nā sensor oxygen dissolved polarographic ma muli o ko lākou mau hiʻohiʻona ʻokoʻa:

1. ʻO ka pololei a me ka ʻike kiʻekiʻe:
   • Hiki ke ʻike i ka oxygen dissolved trace-level, me nā pae ana e like me ka laula o 0.01μg/L a i 20.00mg/L a me nā ʻōlelo hoʻoholo e like me 0.01μg/L. He mea koʻikoʻi kēia no nā noi e like me ka boiler feedwater a me ka nānā ʻana i ka wai ultrapure semiconductor.
2. Manawa pane wikiwiki:
   • Pane maʻamau ma lalo o 60 kekona (hiki i kekahi mau huahana ke loaʻa nā manawa pane i loko o 15 kekona), e noʻonoʻo koke ana i nā loli i nā pae oxygen i hoʻoheheʻe ʻia.
3. Nā Koina mālama haʻahaʻa:
   • ʻAʻole koi pinepine nā hoʻolālā hou i ka hoʻololi pinepine ʻana i ka electrolyte, e hōʻemi ana i nā kumukūʻai mālama lōʻihi a me nā hana. Eia nō naʻe, pono mau ka calibration a me ka pani ʻana o ka membrane.
4. Ka Paʻa Paʻa a me ka Manaʻo Kūʻē Kūʻē:
   • Hoʻokaʻawale maikaʻi ka membrane permeable koho i nā haumia a me nā mea haumia, e hōʻoia ana i nā ana kūpaʻa a hilinaʻi.
5. Uku Uku Mahanahana Aunoa:
   • Loaʻa ka hapa nui o nā mea ʻike i kahi mea ʻike wela i kūkulu ʻia no ka uku wela ʻakomi, hoʻoponopono i nā hewa ana i hoʻokumu ʻia e nā loli wela.
6. Hoʻolālā akamai a hui pū ʻia:
   • Nui nā mea ʻike i hoʻolako ʻia me nā pilina kamaʻilio (e laʻa, RS485) a kākoʻo i nā protocol maʻamau (e laʻa, Modbus), hiki ke hoʻohui i nā ʻōnaehana mana automation a me nā paepae IoT no ka nānā ʻana i ka ʻikepili mamao.

Nā Hōʻike Hoʻohana

Hoʻohana nui ʻia nā sensor oxygen dissolved polarographic ma nā ʻoihana like ʻole:

1. Nā Kaʻina Hana Hana a me ka Hana Wai:
   • ʻO ka nānā ʻana i ka wai ʻai Boiler: Koʻikoʻi i nā ʻoihana e like me ka hana mana, nā kemika, a me ka metallurgy, kahi e hiki ai i ka oxygen dissolved nui ke hoʻomake nui i nā pipeline metala a me nā mea hana.
   • Hoʻomaʻamaʻa wai ʻino a me ka nānā ʻana i ka hoʻokuʻu ʻana: Hoʻopili pololei ka pae o ka oxygen i ka hana microbial i nā kaʻina hana hoʻōla wai ʻona a me nā ʻoihana.
   • ʻO Semiconductor a me Ultrapure Water Production: ʻO nā koi wai maʻemaʻe kiʻekiʻe i ka hana uila e pono ai ka nānā pono ʻana o ka oxygen dissolved trace.
2. Nānā Kaiapuni a me ka ʻImi ʻepekema:
   • Ka nānā ʻana i ka wai o ka wai, ka muliwai, a me ka loko: ʻo ka oxygen dissolved kahi hōʻailona koʻikoʻi o ka hiki ke hoʻomaʻemaʻe pono i ka wai a me ke olakino kaiaola.
   • Aquaculture: ʻO ka nānā ʻana i ka manawa maoli o ka oxygen dissolved e kōkua i ka pale ʻana i ka hypoxia i loko o nā mea ola wai, e hoʻomaikaʻi i ka pono mahiʻai.
3. Biotechnology a me nā ʻoihana lāʻau lapaʻau:
   • Pono e hoʻomalu pono ʻia ka ʻike ʻana o ka oxygen i hoʻoheheʻe ʻia i loko o nā bioreactors (e laʻa, ka fermentation a me ka moʻomeheu cell) no ka hōʻoia ʻana i nā kūlana ulu maikaʻi loa no nā microorganism a i ʻole nā ​​​​pūnaewele.
4. ʻOihana meaʻai a me nā mea inu:
   • Hiki i nā pae oxygen hoʻoheheʻe ke hoʻopilikia i ka ʻono o ka huahana, ka waihoʻoluʻu, a me ke ola o ka mālama ʻana, e pono ai ka nānā ʻana i ka wā hana.

Nā ʻāina/nā ʻāina i hoʻohana mau ʻia

ʻO ka hoʻokomo ʻia ʻana o nā sensor oxygen dissolved polarographic i pili pono i nā pae ʻenehana, nā hoʻoponopono kūlohelohe, a me ka holomua ʻenehana:

1. ʻAmelika ʻĀkau:
   • Hoʻokō ʻo ʻAmelika Hui Pū ʻIa a me Kanada i nā lula palekana kaiapuni a me nā kūlana maikaʻi o ka wai, e hoʻohana nui ʻia kēia mau sensor i nā ʻoihana kiʻekiʻe e like me ka mana, kemika, a me nā lāʻau lapaʻau.
2. ʻEulopa:
   • ʻO nā ʻāina e like me Kelemānia, UK, a me Palani, me nā kulekele kaiapuni koʻikoʻi (e laʻa, ka EU Water Framework Directive) a me nā ʻenehana mālama wai ʻino, ʻo ia nā mea kūʻai nui o kēia mau mea ʻike.
3. ʻAsia-Pākīpika:
   • Kina: Ke ulu wikiwiki nei ka noi ma muli o ka hoʻonui ʻia ʻana o nā hana hoʻomalu kaiapuni (e laʻa, ke kulekele "Water Ten Plan") a me nā hoʻomohala ʻana i ka mālama ʻana i ka wai a me ka iʻa.
   • Iāpana a me South Korea: ʻO nā ʻenehana loea kiʻekiʻe, semiconductor, a me nā ʻoihana kemika pololei e hoʻokau i nā pono like ʻole no nā lako nānā pono wai kiʻekiʻe.
4. Hoʻohana nui nā wahi ʻoihana ʻē aʻe me nā hoʻoponopono kaiapuni koʻikoʻi i kēia mau sensor.

Papa Hōʻuluʻulu

Ka hopena

Polarographic dissolved oxygen sensors, me ko lākou kiʻekiʻe kiʻekiʻe, pane wikiwiki, a me ka paʻa, he mau mea pono i ka nānā ʻana a me ka nānā ʻana i ka wai. He kuleana koʻikoʻi lākou i ka hōʻoia ʻana i ka palekana o ka ʻoihana, ka pono, a me ka palekana o ke kaiapuni.

Hiki iā mākou ke hāʻawi i nā ʻano hoʻonā like ʻole no

1. ʻO ka mika paʻa lima no ka maikaʻi o ka wai

2. Pūnaehana Buoy lana no ka maika'i o ka wai

3. Palaki hoʻomaʻemaʻe ʻakomi no ka ʻike wai ʻokoʻa

4. Hoʻopiha piha i nā kikowaena a me nā polokalamu uila uila, kākoʻo iā RS485 GPRS / 4g / WIFI / LORA / LORAWAN

No ka ʻike wai hou aku ʻike,
