I-Smart Electromagnetic Flowmeter

Uhlolojikelele

I-DWP yochungechunge lwepayipi yochungechunge oluhlakaniphile lwe-electromagnetic flowmeter iyi-flowmeter yokungeniswa kuka-electromagnetic, eklanywe ngokuya nge-JB/T9248-999 "I-Electromagnetic Flowmeter", elungele ukubalwa kokugeleza koketshezi oluqhutshwayo olunokuhanjiswa okukhulu kuno-5us/cm;ububanzi bobubanzi obujwayelekile bungu-5 ukuya ku-3000, kuwuchungechunge lwemikhiqizo ye-electromagnetic flowmeter ehlanganisa ubuhlakani, ukuhlanganiswa okuncane nokungasindi, imisebenzi eminingi, ukunemba okuphezulu nokuthembeka okuphezulu.Iqukethe izingxenye ezimbili: inzwa kanye ne-smart converter.

I-DWP ye-electromagnetic flowmeter inezinhlobonhlobo zokusetshenziswa.Ingakwazi ukukhipha isignali yamanje evamile (4-20mA) ngokuhambisana nephrothokholi yokuxhumana ye-HART ngenkathi ihlangana nokuqapha nokuboniswa kwendawo, ukurekhoda, ukulungisa, nokulawula;ingasetshenziswa kabanzi embonini yamakhemikhali, ukuvikelwa kwemvelo, kanye nemboni yendwangu., i-metallurgy, izimayini, imithi, ukwenza amaphepha, ukuhlinzekwa kwamanzi, ukudla, ushukela, ukuphisa utshwala nezinye izimboni zokulinganisa ukugeleza koketshezi lwamapayipi okuhambisa;ngaphezu kokulinganisa uketshezi olujwayelekile lwe-conductive, ngokwezidingo ezikhethekile zabasebenzisi, ingaphinda ilinganise ukugeleza kwesigaba sesigaba sesibili soketshezi, ukugeleza koketshezi lwe-viscosity ephezulu noketshezi olufana nosawoti, ama-asidi aqinile, nama-alkali aqinile.

Izakhiwo

(1) Inzwa:

Inzwa ngokuyinhloko yakhiwe i-catheter yokulinganisa, i-electrode yokulinganisa, ikhoyili evusa amadlingozi, insimbi eyinsimbi, uzibuthe kanye nendlu.

Ipayipi yokukala: Yakhiwe ngepayipi lensimbi engagqwali, ulayini kanye ne-flange exhumayo, futhi iyisithwali sokulinganisa endaweni yoketshezi oluzolinganiswa.

Ama-electrode okulinganisa: ipheya lama-electrode afakwe odongeni lwangaphakathi lomsele wokulinganisa, oqonde ngqo kusiqondiso sokugeleza kwe-axial, ukuze uketshezi lokulinganisa lukhiqize amasignali.

Ikhoyili ye-Excitation: Amakhoyili e-excitation angaphezulu naphansi akhiqiza amandla kazibuthe ku-catheter yokulinganisa.

I-iron core kanye ne-magnetism: Inkundla kazibuthe ekhiqizwa ikhoyili evusa amadlingozi yethulwa oketshezini bese yenza isekethe kazibuthe.

Igobolondo: iphakethe langaphandle lensimbi.

(2) Isiguquli:

Kuyimitha yesibili ehlakaniphile, ekhulisa isignali yokugeleza futhi ibale ngekhompyutha ye-chip eyodwa ukuze ibonise ukugeleza nenani eliqongelelwe, futhi ingakhipha ama-pulse, i-analog current namanye amasiginali wokulinganisa noma ukulawula ukugeleza koketshezi.

(3) Ifomu lokuhlanganisa umkhiqizo:

Ihlukaniswe yaba izinhlobo ezimbili: uhlobo oludidiyelwe kanye nohlobo lokuhlukaniswa.

Uhlobo oluhlanganisiwe: Inzwa nesiguquli sifakwe esiqeshini esisodwa.

Uhlobo lokuhlukaniswa: Inzwa ne-converter ifakwe ngokuhlukana, futhi uhlelo lwe-flow metering lwakhiwe ngokuxhuma izintambo.Ukuze kuhlangatshezwane nezidingo zokulinganisa okuhlukile kwemidiya, i-lining ne-electrode materials yenzwa ingaba nokukhetha okuningi.

Isimiso sokusebenza

Isimiso sokusebenza se-electromagnetic flowmeter sisekelwe emthethweni ka-Faraday wokungeniswa kwe-electromagnetic.Okusho ukuthi, lapho uketshezi lwe-conductive lugeleza ku-flowmeter ye-electromagnetic, amandla e-electromotive akhangisiwe azokhiqizwa ku-conductor.Amandla e-electromotive akhangwe alingana nezinga lokugeleza koketshezi oluqhubayo, amandla kazibuthe okungeniswa, kanye nobubanzi bomqhubi (ububanzi bangaphakathi be-flowmeter), njengoba kuboniswe esithombeni.

I-electromotive force eyenziwe itholwa yipheya lama-electrode odongeni lwe-flowmeter, futhi izinga lokugeleza lingatholwa ngokubala.

I-electromotive force equation eyenziweyo ithi: E=KBVD

Kufomula: Amandla atholwe ngu-E;D yokulinganisa ishubhu ububanzi bangaphakathi;

B umfutho wokungeniswa kazibuthe;V isilinganiso sokugeleza kwesivinini;

I-K iyi-coefficient ehlobene nokusatshalaliswa kwendawo kazibuthe kanye nobude be-axial.
