Ua hoʻokomo maikaʻi ʻia nā mika kahe o ka hoʻoneʻe maikaʻi ʻana mai SmartMeasurement i nā ʻano hana like ʻole a me nā noi e like me:
ʻAilā & Ke Kinoea
I loko o ka ʻoihana aila a me ke kinoea, pono ka Positive Displacement (PD) Flow Meters no ke ana pololei ʻana i ke kahe ʻana o ka ʻaila ʻaila, nā huahana i hoʻomaʻemaʻe ʻia, a me nā wai kinoea maoli. ʻO ko lākou hiki ke mālama i kahi ākea o nā viscosities e kūpono iā lākou no nā noi e like me ka hoʻoili mālama ʻana, kahi mea koʻikoʻi ke ana pololei e hōʻoia i ke kālepa kūpono a me ka hoʻokō ʻana i nā lula ʻoihana.
Kemika & Petrochemical
Hoʻohana nui ʻia nā mika kahe o PD i ka ʻoihana kemika a me ka petrochemical ma muli o ko lākou hiki ke ana pololei i nā wai viscous a me ka corrosive. He mea koʻikoʻi kēia mau mika no ka nānā ʻana a me ka mālama ʻana i ke kahe ʻana o nā kemika like ʻole i ka wā o ka hoʻoili ʻana, e hōʻoiaʻiʻo ana e kūpaʻa ka hana a palekana. ʻO kā lākou hoʻolālā koʻikoʻi e hiki ai iā lākou ke hana maikaʻi i nā kaiapuni paʻakikī, e mālama pono ana me nā wai paʻakikī.
Ka Ana Waiwai
I ka ana ʻana kālā, kahi e pili pono ai nā hana kālā i ka nui o ka wai i ana ʻia, he hana koʻikoʻi nā mika kahe o PD. Hāʻawi lākou i ka pololei kiʻekiʻe i koi ʻia no nā kumu pili kālā i nā ʻoihana e like me ka aila a me ke kinoea, e hōʻoia ana e ana pololei ʻia ka nui o nā huahana i hoʻololi ʻia, e hōʻemi ana i nā hoʻopaʻapaʻa, a me ka hōʻoia ʻana i ka mālama ʻana i nā kūlana kānāwai.
Kaʻaʻahi wahie
No ka lawe ʻana i ka wahie, pono ʻia nā mika kahe o PD i ke ana ʻana i ka nui o ka wahie i hoʻoili ʻia mai kekahi wahi a i kekahi, e like me ka pahu pahu i ka waiho ʻana a i ʻole ka waiho ʻana i kahi kaʻa. ʻO kā lākou hilinaʻi a me ka pololei e hōʻoia i ka helu ʻia ʻana o kēlā me kēia hāʻule, e hoʻolilo iā lākou i mea hana hilinaʻi i ka logistic o ka hāʻawi wahie.
Nā Pahu Waiwai
Hoʻokomo pinepine ʻia nā mika kahe PD i loko o nā pahu mālama wai e nānā i ke kahe a me ka puka ʻana o nā wai. He mea maʻamau kēia noi i nā ʻoihana kahi e pono ai ka hoʻokele waiwai ʻana, e like me nā mea hoʻolaʻa aila a i ʻole nā mea kanu kemika. ʻO ko lākou hiki ke ana i nā puke nui me ka pololei i nā manawa lōʻihi e hōʻoia i ka mālama pono ʻana a mālama ʻia nā pae waihona.
Meaʻai a me ka inu ua
I ka ʻoihana meaʻai a me ka mea inu, hoʻohana ʻia nā mika kahe PD e ana i nā mea ʻai, hoʻomalu i nā kaʻina hui ʻana, a hōʻoia i ka maikaʻi o ka huahana. ʻO ko lākou hiki ke mālama i nā viscosities wai like ʻole, mai ka wai a hiki i nā syrups, hoʻolilo iā lākou i mea maʻalahi no nā noi e like me ka hoʻoili ʻana i ka waiu, ka brewing, a me ka bottling, kahi i mea nui ai ka pololei a me ka maʻemaʻe.

I ka ʻoihana moana a me nā ʻoihana moku, he mea koʻikoʻi nā mika kahe o PD no ka nānā ʻana i ka hoʻohana ʻana i ka wahie o nā moku a me ka hōʻoia ʻana i ka hoʻololi pololei ʻana o ka wahie a me nā wai ʻē aʻe ma waena o nā moku a me nā hale mālama. ʻO kā lākou hoʻolālā koʻikoʻi e hiki ai iā lākou ke kū i nā kūlana koʻikoʻi o nā kaiapuni moana me ka hāʻawi ʻana i nā ana hilinaʻi a pololei.
Nā Manaʻo o ka Hana Meter Flow
Hoʻohana ʻia nā mīkini hoʻoneʻe maikaʻi o ka oval i ʻelua mau niho niho maikaʻi, hoʻokahi i kau ʻia ma ka ʻaoʻao, a ʻo kekahi ma ke kū pololei, me nā mea e hoʻopaʻa ʻia ana ma ka piko o ka ʻaoʻao kūpaʻa a me ke kikowaena o ke kaʻa paepae, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei. Huli kūʻē nā rotor ʻelua i kekahi i kekahi, e hana ana i kahi hoʻopaʻa i loko o ke ʻano like ʻole o ka crescent ma waena o ka hale a me ke kaʻa. Hiki ke pololei loa nā mita kahe oval inā mālama liʻiliʻi ka paheʻe ma waena o ka hale a me nā mīkini. Inā ʻoi aku ka nui o ka viscosity wai ma mua o 10 cP a ʻoi aku ka nui o ka kahe wai ma luna o 20% o ka mana helu, hiki ke loaʻa ka pololei o 0.1% o ka heluhelu. Ma nā kahe haʻahaʻa a me nā viscosity haʻahaʻa, piʻi ka paheʻe a emi ka pololei i 0.5% o ka heluhelu ʻana a i ʻole.
E like me nā ʻano ʻano ʻē aʻe o ka mīkini kahe hoʻoneʻe maikaʻi, ke hoʻohana ʻia ka mika oval, hiki i nā waiwai lubricating o ka media wai ke hopena i ka ratio turndown kiʻekiʻe i hiki i ka mika ke hoʻokō. Inā ʻaʻohe waiwai lubricating maikaʻi o ka wai i hāʻawi ʻia, pono e hoʻemi ʻia ka wikiwiki o ka rotor i mea e pale ai a hoʻopaʻa i ka lole. ʻO kahi ʻē aʻe, hiki ke kaupalena ʻia ka ʻaʻahu ma ka mālama ʻana i nā hāʻule kaomi ma luna o ke kino mika i emi iho ma mua o 15 psi (<0.1bar). Inā hoʻohana ʻia kēia ʻano hana, ʻo ka hāʻule ʻana o ke kaomi ma luna o ka mika e kaupalena ʻia ke kahe nui loa no nā wai viscosity kiʻekiʻe.
ʻO nā ʻano like ʻole o ka oval gear positive displacement flow meters me ka lobe rotating a me ka impeller-type pd flow meters. ʻO kahi ʻokoʻa nui ma waena o kēia mau mika a me ka mīkini mīkini oval ʻaʻole lākou e kaʻana like i ke kāʻei pololei o ka oval gear PD. Loaʻa i ka mika PD ʻano lobe ʻelua impellers e hoʻololi i nā ʻaoʻao ʻē aʻe o kekahi i loko o ka hale mika. Ke kaʻi ʻana o nā lobes, ʻae ʻia ka nui paʻa o ka wai i ka manawa like a hoʻokuʻu ʻia i waho o ka hale mika. Ma muli o ka noho mau ʻana o nā lobe gears i kahi kūlana pili paʻa, pono wale ke ana ʻana i ka wikiwiki rotational o hoʻokahi mea. Hoʻopili ʻia ka lobe i kahi papa inoa a i ʻole i hui pū ʻia me kahi mea uila helu pulse e like me ka hoʻololi ʻohe a i ʻole Hall Effect. Loaʻa nā mika lobe no nā nui laina mai ka 2 ″ a i ka 24 ″. Hiki ke ana i ka huhu mai 8-10 GPM a hiki i 18,000 GPM no na mika nui. Eia nō naʻe, ʻoi aku ka maikaʻi o ka bi-rotor a i ʻole Helix gear positive displacement mika e like me SmartMeasurement's ALBRPD ma ke ʻano o ka pololei a me ka pae kahe.
Loaʻa ka mika kapa lobe i ka laulā o nā pono hana o ke kūkulu ʻana, mai nā thermoplastics a i nā metala kūpaʻa kūpale. ʻO nā mea maikaʻi ʻole o kēia hoʻolālā me ka nalo ʻana o ka pololei i nā kahe haʻahaʻa. Eia kekahi, ʻoi aku ka liʻiliʻi o ke kahe o kēia mika ma mua o ka piston oscillatory like a i ʻole nā mīkini mika disating.
I loko o kēia mau ʻāpana, ʻike ʻia ka hele ʻana o nā magnet i hoʻokomo ʻia i loko o nā lobes o nā impellers rotating e nā hoʻololi kokoke (maʻamau ʻo Hall-effect type) i kau ʻia ma waho o ke keʻena kahe. Hoʻouna ka mea ʻike i kahi kaʻaahi pulse i kahi counter a i ʻole ka mana kahe. Loaʻa kēia mau mika ma ¹⁄₁₀” a i 6″ ka nui akā e like me ka mea i ʻōlelo ʻia ma luna nei, ke emi nei ka kaulana. I kēia lā, ke hoʻololi nei nā mika oval gear lobe a me ka impeller type positive displacement flow meters ma muli o ko lākou ʻoi aku ka maikaʻi a me ka hiki.
ʻO ka mika helix kahi mea hoʻoneʻe maikaʻi e hoʻohana i ʻelua mau wili helical i hoʻonohonoho pono ʻia (e nānā i ke kiʻi ma lalo) e hoʻopaʻa mau i ka wai o ke kaʻina ke kahe ana. Koi ʻia ke kahe i nā wili helical e huli i ka mokulele o ka paipu. Hoʻohana ʻia nā mea ʻike optical a ʻume mākenēki hoʻi e hoʻopā i kahi kaʻaahi lūlū kūlike i ka wikiwiki o ka wikiwiki o nā wili uila. Liʻiliʻi loa nā ikaika e pono ai e hoʻohuli i nā pāpale a no laila, ke hoʻohālikelike ʻia i nā mika PD ʻē aʻe, haʻahaʻa loa ke kaomi kaomi. ʻO ka ʻoiaʻiʻo kūpono loa e pili ana iā ± 0.1% a i ʻole ka helu.
E like me ka mea i hōʻike ʻia ma lalo nei, piʻi ka hewa o ke ana ʻana i ka hāʻule ʻana o ka kahe o ka hana a i ʻole ka viscosity o ke kaʻina hana. Hiki i nā mika bi-rotor e like me SmartMeasurement's ALBRPD ke ana i ke kahe o nā wai ʻeleʻele loa (mai 3 a 300,000 cP), i mea kūpono no nā wai mānoanoa loa e like me nā glues a me nā polymers viscous loa. No ka mea, ma ke kahe kiʻekiʻe, ʻaʻole pono e ʻoi aku ka nui o ke kaomi ma o ka mika ma mua o 30 psid, hoʻemi ʻia ke kahe o ke kiʻekiʻe i helu ʻia ma o ka mika ke hoʻonui ʻia ka viscosity wai. Inā loaʻa nā ʻano lubricating maikaʻi o ka wai i ke kaʻina hana, hiki i ka huli ana o ka mika ke kiʻekiʻe ma mua o 100: 1, akā ʻoi aku ka maʻamau o ka huli ʻana ma lalo (10: 1).
ʻO nā mika bi-rotor ka mika mika i wae ʻia no nā aila wahie, nā kalaka wahie, a me ka nānā ʻana i ka aila crude. ʻO ke kumukūʻai kiʻekiʻe a me ka volatility o nā kumukūʻai wahie e hana i ka bi-rotor PD mika i mea hana o ke koho no ka mea ʻoi loa, hiki ke hana me ka ʻole o ka mana kūwaho a maikaʻi loa i nā wahi i hoʻopaʻa ʻia kahi i loaʻa ʻole kahi kahe paipu pololei a i ʻole nā palena pololei i hiki ke loaʻa. E ʻike kā mākou pdf no ka ʻike hou aku. Kaulana loa kēia kaila mika no nā noi hoʻoili mālama. ʻO nā moku lawe moku he mau manawa ma waho o ke awa kahi e hiki ai ke hoʻololi i nā kumukūʻai wahie, no laila kūʻai ʻia ka nui o ka wahie ke hele mai i ke awa i kahi hoʻololi hoʻololi mālama a hoʻohana ʻia kahi mika e like me kēia no ka hana.
Pono e hoʻohana ʻia nā mika PD me nā wai maʻemaʻe a me nā wai ʻaʻohe kinoea a i ʻole ea. Pono e wehe ʻia nā ʻāpana ʻoi aku ma mua o 100 microns ma ke kānana ʻana. Eia naʻe, hiki i nā kānana a i ʻole nā kānana e like me SmartMeasurement ALPDFT ke hoʻopau i nā ʻāpana mai ka wai ma mua o ka hiki ʻana i ka mika PD.
ʻAʻole pili ka pololei i ke kahe ʻana ke ʻole ke komo ʻana i ka ea a i ʻole ke kinoea i loko o ka wai. Hiki i ka mika PD ke hoʻokipa i nā kahe ʻana i ka wā e komo ai ka ea ma o ka hoʻohana ʻana i ka ea/gas eliminator e like me ka SmartMeasurement ALPDGE a i ʻole ka ALPDFTG e hoʻohui i kahi mea kānana. Hoʻokomo ʻia kēia mau mea hana i uka o ka mika e kikeke i nā kinoea ma mua o ke ana ʻana o ka wai. Ma muli o ka paʻa paʻa o loko o ke keʻena ana o ka PD mika a ma waena o nā mea hoʻoheheʻe waena, he mea nui ia e maʻemaʻe ka pāpaʻi no ka mea hiki i ka helu ʻāpana nui a i ʻole ka nui o nā ʻāpana nui ke hopu i ka mika. No nā noi e like me ka nānā ʻana i ka hoʻopuka ʻana i ka ʻoihana ʻaila a me ka ʻaila kahi i loaʻa ai nā ʻāpana e like me ke one a i ʻole nā pōhaku i hoʻokomo ʻia i loko o ka wai, ʻo ka ALPDFTG ke koho maikaʻi loa.
