I kēia manawa, kā mākou a pau Transit-Time ultrasonic kahe ana mikahoʻohana ʻia no ke ana kahe wai a ʻO ka paipu i ana ʻia he paipu wai piha.Hoʻohana pinepine ʻia ka mīkini kahe wai manawa transit i nā mea kanu wai, noi HVAC, hale hana lāʻau, hale hana meaʻai, ʻoihana inu, ʻoihana metallurgy a me nā mea ʻē aʻe.Hiki ke hoʻokaʻawale ʻia kā mākou Transit-Time ultrasonic flowmeter i hoʻokahi channel ultrasonic flow meter, Dual-channel ultrasonic flow meter, multi-channel ultrasonic flow meter.
Hoʻokahi ala kani ultrasonic kahe mikame hoʻokahi paʻi paʻa a i ʻole nā mea ʻike hoʻokomo
ʻElua kaha kani ultrasonic kahe mikame ʻelua mau paʻi paʻi ʻana a i ʻole nā ʻano ʻano hoʻokomo
Hoʻokomo ʻia ka mīkini kani kani ultrasonic me 4 mau mea ʻike hoʻokomo
Ua kūpono lākou no ke ana ʻana i nā wai maʻemaʻe pili, ka wai me ka liʻiliʻi o nā mea paʻa,hiki i ka pololei ke hiki i 1%, ka pololei o ka lua kani ultrasonic flowmeter hiki ke piʻi i ka 0.5%.
Ma ka ʻoihana kemika, ka hoʻomaʻamaʻa wai, ka ʻaila a me nā ʻoihana ʻē aʻe e hoʻohana i nā flowmeters e ana i nā ʻano wai like ʻole, e like me ka wai kemika, ka wai paila, ka wai ʻoihana, ka wai ʻōpala home a pēlā aku.A i ka lāʻau lapaʻau, meaʻai a me nā ʻoihana ʻē aʻe, loaʻa iā lākou nā kūlana koʻikoʻi i ka maikaʻi o ka wai no ke ana ʻana, pono lākou e ana i ke kahe o ka wai maʻemaʻe a i ʻole ka wai ultra-maʻemaʻe, e haʻahaʻa loa ka conductivity wai maʻemaʻe.
No ke aha e hoʻopaʻa ai i ke ʻano transit time ultrasonic flowmeter ka hopena maikaʻi loa e ana i ka wai maʻemaʻe?
E ʻae mai iaʻu e lawe i kekahi mau ʻano mika kahe kaulana e like me ka hoʻohālikelike ʻana.
1. Electromagnetic flowmeter
Hoʻokumu ʻia ka mīkini kahe electromagnetic ma ke kānāwai Faraday o ka hoʻokomo electromagnetic.Hoʻohana ʻia ia e ana i ka kahe kahe o ka wai conductive me ka conductivity ʻoi aku ma mua o 5μS/cm.He mika inductive no ke ana ana i ka leo kahe o ka medium conductive.
Hiki ke hoʻohana ʻia kēia mika no ke ana ʻana i ka kahe kahe o ka wai corrosive ikaika e like me ka waikawa ikaika a me ke kumu ikaika a me ka wai homogeneous-solid ʻelua-phase suspended wai e like me ka lepo, pulp a me ka pulp pepa.No ka mea, ʻo ka conductivity o ka wai maʻemaʻe he 0.055 μS / cm wale nō, ʻoi aku ka haʻahaʻa ma mua o 5μS / cm, ʻike ʻia ʻaʻole kūpono nā flowmeters electromagnetic no ke ana ʻana o kēia wai.
2. ʻO ka mīkini kahe kahe ʻana o ka turbine
Hoʻohana ʻia nā mika kahe turbine i ka ikehu mechanical o ka wai e hoʻohuli i kahi rotor i loko o ke kahawai kahe.Hoʻohālikelike pololei ka māmā holo kaʻa i ka wikiwiki o ka wai e holo ana ma ka mika.
Hiki ke ʻike ʻia ʻo ka turbine flowmeter kahi ana hoʻopili pili, a ʻo ka wai maʻemaʻe he kiʻekiʻe koʻikoʻi nā koi waiwai, no laila pono e hoʻohana ʻia ka mea nui i ka hana ʻana o 316L, ka hoʻohana ʻana i ka hui hoʻomaʻemaʻe maʻemaʻe, piʻi koke ke kumukūʻai hana.
3. Vmika kahe o ka ortex,Mika uila uila, mika kahe PD
ʻO nā mika kahe o ka vortex, i ʻōlelo pinepine ʻia ʻo vortex shedding flow meters, hoʻohana i kahi keakea i ke kahawai e hana i nā vortex i lalo i hana ʻia ma kēlā ʻaoʻao kēia ʻaoʻao o ke keakea.I ka hoʻokahe ʻia ʻana o kēia mau vortices mai ke keakea, hana lākou i nā ʻāpana haʻahaʻa haʻahaʻa a me ke kaomi kiʻekiʻe e oscillate i kekahi mau alapine e like me ka wikiwiki o ka wai.Hiki ke helu ʻia ke kahe kahe mai ka wikiwiki o ka wai.
ʻO nā mika kahe o ka turbineno ka hoʻohana ʻana me nā wai he manaʻo maʻalahi o ka hana, ʻoiai ke kahe ʻana o ka wai i loko o ka paipu o ka mika kahe e pili ana i nā lau turbine.Hoʻohuli ʻia nā ʻāpana turbine ma ka rotor e hoʻololi i ka ikehu mai ka wai kahe i ka ikehu rotational.ʻO ke kumu o ka rotor e wili ai ma luna o nā bearings, no ka mea, hoʻonui ka wikiwiki o ka wai i ka holo wikiwiki ʻana o ka rotor.ʻO nā kipi i kēlā me kēia minuke a i ʻole RPM o ka rotor e pili pono ana i ka wikiwiki o ka holo ʻana i loko o ke anawaena o ka paipu kahe a pili kēia i ka leo ma kahi ākea.
ʻO nā mika kahe hoʻoneʻe maikaʻie hoʻohana i ʻelua impellers patented (gears) e ana i ka nui pololei o ka wai e hele ana ma ka mika kahe i ka wā e kaʻawili ai nā mea hana.Hoʻolālā ʻia kēia mau mika kahe e ana pono i nā wai mānoanoa e like me resins, polyurethanes, adhesives, paints, a me nā petrochemical like ʻole.
ʻO ia ke ʻano o ke ana kahe wai, no laila e pili pono lākou me ka wai, e hoʻohaumia i ka wai i ana ʻia.
4. ʻO Coriolis Mass Flowmeter
Loaʻa i ka mīkini kahe Coriolis kahi paipu i hoʻoikaika ʻia e ka haʻalulu paʻa.Ke hele ka wai (ke kinoea a wai paha) i loko o kēia paipu, e hoʻololi ka manawa kahe nui i ka haʻalulu o ka paipu, e wili ka paipu i ka hopena o ka hoʻololi ʻana.Hiki ke ana ʻia kēia hoʻololi ʻāpana a loaʻa ka hua laina laina e like me ke kahe.
E like me ke ana ʻana o ke kumu Coriolis i ka kahe nui ʻana me ka mea i loko o ka paipu, hiki ke hoʻopili pololei ʻia i kekahi wai e kahe ana ma loko o ia mea - LIQUID a i ʻole GAS - ʻoiai nā mika kahe wai wela e pili ana i nā waiwai kino o ka wai.Eia kekahi, e like me ka neʻe ʻana o ka pae i ke alapine ma waena o ka inlet a me ka puka, hiki nō ke ana i ka loli maoli i ka alapine maoli.ʻO kēia hoʻololi i ke alapine e pili pono ana i ka nui o ka wai - a hiki ke loaʻa kahi hōʻailona hōʻailona hou.Ma hope o ke ana ʻana i ka nui o ke kahe kahe ʻana a me ka mānoanoa, hiki ke loaʻa i ka nui kahe kahe.
I kēia mau lā, ʻoi aku ka maikaʻi o kēia mika ke ana i 200mm a i ʻole ma lalo o ke anawaena paipu, ʻaʻole hiki ke ana i ka paipu anawaena nui;ʻOi aku ka nui o ke kaumaha a me ka nui, ʻaʻole maʻalahi ke mālama.
No ke ana kahe wai maʻemaʻe, hiki iā ʻoe ke koho i ka mika kahe e pili ana i nā kūlana aʻe.
1) E koho i ka mīkini kahe wai ʻano invasive ʻole a ʻaʻohe hoʻopili pololei me ka wai i ana ʻia e hōʻoia ʻaʻole i haumia ka wai;
2) Pono ka mīkini kahe i koho ʻia ke ana i nā wai me ka haʻahaʻa haʻahaʻa.
3) ʻAʻole e hoʻopili ʻia ka hoʻokomo ʻana a me ke ana ʻana o ka mika kahe e ke anawaena o ka paipu ana.
ʻO ka hoʻopaʻa ʻana o waho ma ka ultrasonic flowmeter kahi ʻano o ka mika wai kahe ʻole, hiki ke ana i ka paipu mai 20mm a 5000mm, kahi ākea ākea o ka paipu, a hiki ke hoʻohana ʻia e ana i nā wai paʻakikī e hoʻopili a nānā.He kiʻekiʻe ka pololei, ʻaneʻane ʻaʻohe keakea ʻana i nā waiwai kino like ʻole o ka mea i ana ʻia, e like me ka corrosive ikaika, non-conductive, radioactive, flammable and explosive wai a me nā pilikia ʻē aʻe.No laila, no ke ana ʻana i ka wai maʻemaʻe, e ʻōlelo mua mākou i ka mīkini kahe kani ultrasonic hoʻopili waho e ana.
Hōʻike i kekahi mau hihia maoli no kāu kuhikuhi.
