Nā Mīkini Kahe Electromagnetic no nā Wai Alakaʻi: Kūpono no nā ʻĀpana Meaʻai, Lāʻau Lapaʻau a me Petrochemical

Ma ke kikowaena o ke kūpono o nā mika kahe electromagnetic no nā wai conductive ʻo ia ke Kānāwai o Faraday no ka Electromagnetic Induction. ʻAʻole e like me nā mika kahe mechanical e hilinaʻi nei i nā ʻāpana neʻe (hiki ke pani, hoʻopau, a hoʻohaumia paha i nā wai conductive), hoʻohana nā magmeters i kahi hoʻonohonoho non-intrusive: kahi paipu i hoʻopaʻa ʻia me kahi mea insulating, i hoʻopuni ʻia e nā coils electromagnetic. Ke kahe kahi wai conductive ma o ka paipu, ʻoki ia ma ke kahua magnetic i hana ʻia e nā coils, e hana ana i kahi voltage uila liʻiliʻi. ʻO ka nui o kēia voltage e pili pono ana i ka wikiwiki o ka wai—e ʻae ana i ka mika e helu i ka helu kahe me ka pololei loa (maʻamau ± 0.5% o ka heluhelu ʻana, a hiki i ka ± 0.1% no nā hiʻohiʻona kiʻekiʻe). Hoʻopau kēia hoʻolālā i ka pilina ma waena o nā ʻāpana ʻike o ka mika a me ka wai, kahi pono nui no nā wai conductive i hiki ke corrosive, viscous, a i ʻole ka waiho ʻana i nā koena.

No ka ʻoihana meaʻai, kahi i hiki ʻole ai ke kūkākūkā ʻia ke ʻano maʻemaʻe a me ka maʻemaʻe o ka huahana, he mea hoʻololi pāʻani nā mika kahe electromagnetic. Pono nā wai conductive e like me nā wai huaʻai, nā huahana waiū, nā mea ʻono, a me nā syrup i nā lako e hoʻokō i nā kūlana FDA (Food and Drug Administration) a i ʻole EU 10/2011 e pale aku i ka haumia. ʻO nā uhi palupalu a ʻaʻohe crevice o nā Magmeters (i hana pinepine ʻia me nā mea ʻai e like me PTFE a i ʻole ETFE) e pale aku i ka hōʻiliʻili ʻana o ka wai a he maʻalahi hoʻi e hoʻomaʻemaʻe—koʻikoʻi no ka pale ʻana i ka ulu ʻana o ka bacteria ma waena o nā holo hana. I loko o kahi hale hana inu nui, no ka laʻana, hoʻohana ʻia nā magmeters e ana i ke kahe o ka syrup conductive i loko o nā pahu hui: ʻo kā lākou pololei e hōʻoiaʻiʻo i ka ʻono mau ma waena o nā ʻāpana, ʻoiai ʻo kā lākou hoʻolālā ʻaʻole e komo hewa e hoʻopau i ka pilikia o nā ʻāpana metala (mai nā ʻāpana mīkini i ʻaʻahu ʻia) e haumia ana i ka huahana. Eia kekahi, mālama nā magmeters i ka viscosity kiʻekiʻe o nā wai e like me ke kokoleka a i ʻole ka meli me ka ʻole o ka clogging, kahi pilikia maʻamau me nā mika kuʻuna e hilinaʻi nei i nā impellers.

ʻOi aku ka paʻakikī o nā koi o ka ʻāpana lāʻau lapaʻau, ʻoiai ʻo nā wai conductive (e like me nā lāʻau lapaʻau wai, ka wai sterile, a me nā mea hoʻoheheʻe kemika) pono e hoʻokō i nā kūlana kaohi maikaʻi a me ka hiki ke hahai ʻia. ʻOi aku ka maikaʻi o nā mika kahe electromagnetic ma aneʻi ma ka hāʻawi ʻana i nā ana pololei a hiki ke hana hou ʻia - he mea nui no ka hōʻoia ʻana i loaʻa i nā ʻano lāʻau lapaʻau ka nui kūpono o nā mea hana. Kākoʻo pū kā lākou hoʻolālā ʻaʻole e komo i ka hana sterile: ʻoiai ʻaʻohe ʻāpana e neʻe ana i loko o ka paipu, ʻaʻohe pilikia o ka hana ʻana o nā ʻāpana a i ʻole ka haumia keʻa ma waena o nā ʻāpana. ʻO kahi mea hana lāʻau lapaʻau e hana ana i nā lāʻau injectable, no ka laʻana, hoʻohana i nā magmeters e nānā i ke kahe o ka hopena saline conductive i loko o nā vials. ʻO ka hoʻouna ʻikepili manawa maoli o nā mika e hiki ai i ka mea kanu ke hahai i kēlā me kēia ʻanuʻu o ke kaʻina hana, e hōʻoiaʻiʻo ana i ka mālama ʻana me nā kino hoʻoponopono e like me ka FDA a me EMA (European Medicines Agency). Eia kekahi, kūʻē nā magmeters i nā mea hoʻomaʻemaʻe ʻino (e like me ka hydrogen peroxide) i hoʻohana ʻia i nā hale hana lāʻau lapaʻau, e hōʻoiaʻiʻo ana i ka hilinaʻi lōʻihi.

I loko o ka ʻoihana petrochemical, kahi e kū ai nā wai conductive mai ka ʻaila maka a me ka gasoline a hiki i nā mea hoʻoheheʻe ʻoihana a me ka wai hoʻoneoneo, hoʻoponopono nā mika kahe electromagnetic i kekahi o nā hana ana paʻakikī loa. He mea nui ka palaho ma ʻaneʻi—he nui nā wai petrochemical he palaho loa, a hiki i nā mika mechanical me nā ʻāpana metala ke palaho koke, e alakaʻi ana i nā heluhelu pololei ʻole a me nā leaka pipiʻi. ʻO nā uhi pale palaho o nā Magmeters (e like me ka rubber a i ʻole ka keramika) a me nā ʻāpana pulu ʻole i kū i kēia mau wai ʻino, e hoʻolōʻihi ana i ko lākou ola i 10-15 mau makahiki (hoʻohālikelike ʻia me 3-5 mau makahiki no nā mika mechanical). Eia kekahi, hana pinepine nā hale hana petrochemical ma lalo o nā kūlana kiʻekiʻe a me ke ana wela, a loaʻa nā magmeters i nā hoʻolālā paʻakikī e lawelawe i nā kaomi a hiki i 1,000 bar a me nā mahana mai -40°C a 200°C. No ka laʻana, hoʻohana kahi hale hoʻomaʻemaʻe i nā magmeters e ana i ke kahe o ka ʻaila maka conductive ma o nā pipelines: kōkua ko lākou pololei i ka hoʻomaikaʻi ʻana i nā kaʻina hana hoʻomaʻemaʻe, hoʻemi i ka ʻōpala, a hōʻoia i ka lawe palekana—koʻikoʻi no ka pale ʻana i nā ninini ʻana o ke kaiapuni a me ka hoʻokō ʻana i nā lula palekana.

ʻOiai ʻoi aku ke kiʻekiʻe o ke kumukūʻai mua o nā mika kahe electromagnetic ma mua o nā koho mechanical, ʻoi aku ka nui o kā lākou mau pono lōʻihi no ka meaʻai, nā lāʻau lapaʻau, a me nā ʻāpana petrochemical ma mua o kēia hoʻopukapuka kālā. ʻO ka hoʻemi ʻana i nā kumukūʻai mālama (ʻaʻohe ʻāpana neʻe e pani), ka emi ʻana o nā hoʻihoʻi huahana (ma muli o ka pale ʻana i ka haumia), a me ka hoʻomaikaʻi ʻana i ka pono hana (ma o ka ʻikepili pololei) e alakaʻi i kahi hoʻihoʻi maʻamau ma ka hoʻopukapuka kālā i loko o 2-3 mau makahiki. No nā ʻoihana kahi hiki i nā hewa ana liʻiliʻi ke loaʻa nā hopena pōʻino - mai ka meaʻai i palaho ʻia a hiki i nā lāʻau lapaʻau maikaʻi ʻole a i ʻole nā ​​​​pōʻino kaiapuni - ʻaʻole wale nā ​​​​magmeters he mea hana, akā he palekana.

I ka hoʻomau ʻana o ka ulu ʻana o nā ʻoihana meaʻai, lāʻau lapaʻau, a me ka petrochemical, me nā lula paʻa a me nā koi e ulu ana no ka hoʻomau ʻana, ʻo nā mika kahe electromagnetic ke kūlana gula no ke ana ʻana o ka wai conductive. ʻO ko lākou hiki ke hoʻohui i ka pololei, ka maʻemaʻe, a me ke kūpaʻa e lilo ai lākou i mea nui no ka hōʻoia ʻana i ka maikaʻi o ka huahana, ka palekana hana, a me ka mālama ʻana i ke kaiapuni. No kekahi hale hana e hana ana me nā wai conductive, ʻoi aku ka nui o nā magmeters ma mua o kahi hopena ana—he mea hoʻokele nui lākou i ka holomua i kahi ʻāina hoʻokūkū a hoʻoponopono ʻia.
