Ka helu a me ke koho ʻana i ka laulā o Vortex Flowmeter

Hiki i ka vortex flowmeter ke ana i ke kahe o ke kinoea, ka wai a me ka mahu, e like me ke kahe o ka leo, ke kahe nui, ke kahe o ka leo, a me nā mea ʻē aʻe.ʻO ia ke ʻano nui o ke ana ʻana o ka wai i nā pipeline ʻoihana a loaʻa nā hopena ana maikaʻi.

Nui ka laulā ana o ka vortex flowmeter, a liʻiliʻi ka mana o ke ana.No ka laʻana, ʻaʻole e pili ka nui o ka wai, kaomi, viscosity, etc. i ka hana ana o ka vortex flowmeter, no laila ikaika loa ka hana.

ʻO ka pōmaikaʻi o ka vortex flowmeter ʻo ia kona ʻano ana nui.ʻO ka hilinaʻi kiʻekiʻe, ʻaʻohe mālama mīkini, no ka mea ʻaʻohe ʻāpana mechanical.Ma kēia ala, ʻoiai inā lōʻihi ka manawa ana, hiki ke kūpaʻa nā ʻāpana hōʻike.Me ka mīkini kaomi, hiki iā ia ke hana i ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka mahana wela me ka adaptability ikaika.Ma waena o nā mea ana like, ʻo ka vortex flowmeter ka koho kūpono.I kēia manawa, nui nā hale hana e hoʻohana i kēia ʻano mea hana e ana i ka waiwai i ʻoi aku ka maikaʻi a me ka pololei.

No ka laʻana: 0.13-0.16 1/L, hiki iā ʻoe ke koho i ka bai iā ʻoe iho, e ana i ka laula o ke kolamu triangle, a ʻo ka ʻāpana Straw du Hall ma waena o 0.16-0.23 (helu ʻia ma 0.17).

f=StV/d formula (1)

Aia i hea:

f-Carman vortex frequency i hana ʻia ma kekahi ʻaoʻao o ka mīkini hana

Helu St-Strohal (helu ʻano ʻole)

V-ka awelika kahe o ka wai

d-ka laulā o ka vortex generator (e nānā i ka ʻāpana)

Ma hope o ka helu ʻana i ke alapine

K=f*3.6/(v*D*D/353.7)

K: huina kahe

f: ʻO ka pinepine i hana ʻia ma ke kahe kahe i hoʻonohonoho ʻia

D: Kaliber mika kahe

V: Kahe kahe

ʻO ke koho ʻana i ka laulima kahe kahe Vortex

ʻOkoʻa ka hana a me ka mana o ka mana keʻokeʻo a me ka Du power amplifier o ka vortex flowmeter.

1. ʻO ka vortex flowmeter me nā hana maʻalahi e pili ana i kēia mau koho koho.
ʻO ke koena mea kani, ʻoki ʻoki liʻiliʻi i ka hōʻailona, ​​​​e pili ana i ka pae puka 4-20mA, ka laʻana a i ʻole ka manawa damping, ka hoʻomaʻemaʻe ʻana, etc.

2. Eia kekahi, ʻo ka ʻoi aku ka piha o ka vortex flowmeter e loaʻa pū kekahi i kēia mau koho koho.
Ana ʻano ʻano, hoʻonohonoho uku hoʻokahe, ʻāpana kahe, ʻano hōʻailona hoʻopuka, ka wela o luna a me ka palena haʻahaʻa, kaomi ma luna a me ka palena haʻahaʻa, kaomi o ka lewa kūloko, ka nui o ke kūlana maʻamau, ka hoʻonohonoho kamaʻilio.
