Hōʻikeʻike ʻo Vortex Flow Meters
ʻO nā mika kahe o Vortex nā mea hana hou e ana i ka kahe wai ma ka ʻike ʻana i nā vortices i hana ʻia i ka wā e hele ai ka wai i kahi mea bluff. ʻOi aku ka maikaʻi o kēia mau mika i ke ana ʻana i nā wai, nā kinoea, a me ka mahu, e like me ka ea i hoʻopaʻa ʻia a me ka mahu saturated, me ka ʻole o nā ʻāpana neʻe. Hāʻawi nā mika kahe o Vortex i ka hilinaʻi a me ka mālama haʻahaʻa ma waena o nā noi ʻoihana like ʻole, mai ka aila a me ke kinoea a hiki i ka hana mana.
Hana ʻia nā mika kahe o Vortex ma ke kumu o ka vortex shedding, kahi mea i ʻike mua ʻia e Theodore von Kármán. Ke kahe ka wai a puni kekahi mea ʻaʻole i hoʻoheheʻe ʻia (kino bluff) i ka mika, hana ia i nā vortices. ʻO ke alapine o kēia mau vortices e pili pono ana i ka wikiwiki o ke kahe ʻana o ka wai, e ʻae ana i ke ana ʻana o ke kahe pololei ma kahi ākea ākea.
ʻO nā hiʻohiʻona koʻikoʻi o ka Vortex Flow Meter me:
- Hua'ōlelo: Hiki ke ana i na wai like ole, e like me ka ea compressed a me ka mahu
- pololei: Hāʻawi i nā ana pololei no ka hana mau
- Durability: ʻAʻohe ʻāpana hoʻoneʻe, e hopena i ka lole haʻahaʻa a me ka mālama ʻana
- ʻO ke kūlana: Haʻahaʻa haʻahaʻa i nā ʻano like ʻole o nā kūlana kaʻina
- Ka hoʻokō kāki: Hāʻawi i kahi kaulike o ka hana a me ka uku
ʻIke ʻia ka loina vortex-shedding ma ke ʻano, e like me ka hana ʻana o ka makani i nā nalu i loko o ka hae. Ma nā ʻoihana ʻoihana, hoʻohana ʻia kēia kumukānāwai i loko o kahi ʻōnaehana paipu paʻa, kahi i loaʻa ai ka hopena vortex a ana ʻia e hoʻoholo ai i nā kahe kahe.
He mea waiwai nui nā mika kahe o Vortex i nā noi kahi e pilikia ai ka hoʻokomo ʻana i nā ʻāpana neʻe. ʻO kā lākou hoʻolālā koʻikoʻi, maʻamau e hōʻike ana i ke kila kila a i ʻole ke kūkulu ʻana ʻo Hastelloy, kūpono iā lākou no nā wahi ʻoihana paʻakikī.

Ma ka hui pū ʻana i kēia mau hiʻohiʻona a me nā pōmaikaʻi, hāʻawi ʻo vortex flow meter i kahi hopena paʻa a maʻalahi no ka nui o nā pilikia ana i ke kahe ʻana ma waena o nā ʻoihana like ʻole. ʻO kā lākou mau kumumanaʻo hoʻolālā e hōʻoia i ka hana pololei, hilinaʻi me ka mālama liʻiliʻi, e hoʻolilo iā lākou i koho kūpono no nā hana lōʻihi.
Nā noi a me nā palena
Hāʻawi ʻo Vortex flow meter i nā hāʻina maʻamau no ke ana kahe ʻana ma waena o nā ʻoihana like ʻole. ʻOi maikaʻi lākou i ke ana ʻana i ke kinoea maoli, nā wai like ʻole me nā viscosities haʻahaʻa, nā kemika corrosive, nā mea hoʻoheheʻe, a me ke kahe mahu. Pono pono nā mita kahe o Vortex no ka nānā ʻana i ka pono o ka boiler a me ke ana ʻana i ka ea paʻa a me ka mahu saturated i nā kaʻina hana.
Nā noi ʻenehana
- Oil, a me Ke Kinoea: ʻOi aku ka maikaʻi o nā mita Vortex i ke ana ʻana i ke kinoea maoli, ka mahu no kā lākou mau paila.
- Ka Hoʻolālā Kūlohelohe: Hoʻohana nui ʻia kēia mau mika no ke ana ʻana i nā kemika corrosive a me nā solvents ma muli o kā lākou hana paʻa a me nā ʻāpana neʻe liʻiliʻi.
- Ka mana hana: I loko o nā mea kanu mana, ana pololei nā mika vortex i ke kahe mahu, koʻikoʻi no ka nānā ʻana i ka pono o ka paila a me ka hana holoʻokoʻa o nā mea kanu.
- ʻO ka meaʻai a me ka mea inu: ʻO ka hoʻolālā hoʻomaʻemaʻe o kekahi mau mika vortex e kūpono iā lākou no ke ana ʻana i nā kahe i ka hoʻoili ʻana i nā meaʻai, ʻoi aku hoʻi no nā wai maʻemaʻe a me ka mahu.
