I-Smart Electromagnetic Flowmeter

Isishwankathelo

Uluhlu lwemibhobho yoluhlu lwe-DWP olukrelekrele lokuqukuqela kwe-electromagnetic flowmeter yi-electromagnetic induction flowmeter, eyilwe ngokwe-JB/T9248-999 "i-Electromagnetic Flowmeter", ilungele ukubala ukubala kolwelo oluqhubayo olunokuhanjiswa okukhulu kune-5us/cm;Uluhlu lwedayamitha ye-5 ukuya kwi-3000, luluhlu lweemveliso ze-electromagnetic flowmeter ezidibanisa ubukrelekrele, ukudibanisa okuncinci kunye nokukhaphukhaphu, imisebenzi emininzi, ukuchaneka okuphezulu kunye nokuthembeka okuphezulu.Iqulethwe ngamacandelo amabini: inzwa kunye ne-smart converter.

I-DWP electromagnetic flowmeter inoluhlu olubanzi losetyenziso.Iyakwazi ukuvelisa umqondiso oqhelekileyo wangoku (4-20mA) ngokuhambelana neprotocol yonxibelelwano lwe-HART ngelixa udibana nokubeka iliso kwindawo kunye nokubonisa, ukurekhoda, ukulungiswa kunye nokulawula;inokusetyenziswa ngokubanzi kwishishini lemichiza, ukhuseleko lokusingqongileyo, kunye noshishino lwamalaphu., i-metallurgy, imigodi, amayeza, ukwenza iphepha, unikezelo lwamanzi, ukutya, iswekile, ukutywala kunye namanye amashishini okulinganisa ukuhamba kwamanzi kwimibhobho ye-conductive;ukongeza ekulinganiseni ulwelo conductive jikelele, ngokweemfuno ezikhethekileyo zabasebenzisi, kwakhona ukulinganisa conductive ulwelo-oluqilima izigaba ezibini Flow, ukuhamba ulwelo viscosity eliphezulu kunye nolwelo ezifana neetyuwa, iiasidi eyomeleleyo, kunye alkalis eyomeleleyo.

Izakhiwo

(1) Uluvo:

I-sensor ikakhulu yenziwe yi-catheter yokulinganisa, i-electrode yokulinganisa, i-coil yokuvuselela, i-iron core, i-magnet kunye nendlu.

I-conduit yokulinganisa: Iqulunqwe ngumbhobho wensimbi engenasici, i-lining kunye ne-flange yokudibanisa, kwaye ngumthwali wokulinganisa kwi-site yolwelo oluza kulinganiswa.

Ukulinganisa i-electrodes: i-electrodes efakwe kwindonga yangaphakathi ye-conduit yokulinganisa, i-perpendicular ukuya kwi-axial flow direction, ukwenzela ukuba ulwelo lokulinganisa luvelise iimpawu.

Ikhoyili ye-excitation: Iikhoyili ezivuselelayo eziphezulu nezisezantsi ezivelisa imagnethi kwi-catheter yokulinganisa.

Undoqo wentsimbi kunye nemagnethi: Umhlaba wemagnethi oveliswe yicoil yokuvuselela ungeniswa kulwelo kwaye wenze isekethe yemagnethi.

Iqokobhe: ukupakishwa kwangaphandle kwesixhobo.

(2) Isiguquli:

Iyimitha yesibini ekrelekrele, eyandisa umqondiso wokuhamba kwaye ibala ngekhompyuter enye-chip ukubonisa ukuhamba kunye nenani eliqokelelweyo, kwaye inokuvelisa i-pulse, i-analog current kunye nezinye iimpawu zokulinganisa okanye ukulawula ukuhamba kwamanzi.

(3) Ifom yokuhlanganisa imveliso:

Ukwahlula kwiifom ezimbini: uhlobo oludibeneyo kunye nohlobo lokwahlula.

Uhlobo oludibeneyo: Inzwa kunye nesiguquli sifakwe kwisiqwenga esinye.

Uhlobo lokwahlula: I-sensor kunye ne-converter ifakwe ngokwahlukileyo, kwaye inkqubo yokulinganisa i-flow metering yenziwa ngokudibanisa iintambo.Ukuze kuhlangatyezwane neemfuno zemilinganiselo eyahlukeneyo yemidiya, i-lining kunye ne-electrode materials of the sensor can have many choices.

Umgaqo wokusebenza

Umgaqo osebenzayo we-electromagnetic flowmeter usekwe kumthetho kaFaraday wokungeniswa kombane wombane.Oko kukuthi, xa ulwelo oluqhubayo luhamba nge-electromagnetic flowmeter, i-electromotive force induced iya kwenziwa kwi-conductor.Amandla e-electromotive eyenziweyo alingana nesantya sokuhamba kolwelo oluqhubayo, amandla okungenisa imagnethi, kunye nobubanzi bomqhubi (ububanzi bangaphakathi be-flowmeter), njengoko kubonisiwe kumfanekiso.

I-electromotive force eyenziwe ifunyenwe ngamabini e-electrode eludongeni lwe-flowmeter, kwaye izinga lokuhamba linokufumaneka ngokubala.

I-equation ye-electromotive force equation yile: E=KBVD

Kwifomula: E inokubakho;D yokulinganisa ityhubhu yedayamitha yangaphakathi;

B ubukhulu bemagnethi bokungeniswa;V umyinge wesantya sokuqukuqela;

I-K yi-coefficient enxulumene nosasazo lwemagnethi kunye nobude be-axial.
