Ubwenge bwa Electromagnetic Flowmeter

Incamake

Umuyoboro wa DWP wubwoko bwubwenge bwa electromagnetic flowmeter numuyoboro wa electromagnetic induction flowmeter, wakozwe ukurikije JB / T9248-999 "Electromagnetic Flowmeter", ibereye kubara imigendekere yimyunyu ngugu irenze 5us / cm;urutonde rwa diameter nomero ni 5 kugeza 3000, ni urukurikirane rwibicuruzwa bya electromagnetic flumeter yibikoresho bihuza ubwenge, bito bito kandi byoroheje, guhuza ibikorwa, byinshi, byuzuye kandi byizewe.Igizwe n'ibice bibiri: sensor hamwe nuhindura ubwenge.

DWP electromagnetic flowmeter ifite uburyo bwinshi bwo gukoresha.Irashobora gusohora ibimenyetso bisanzwe bigezweho (4-20mA) bijyanye na protocole y'itumanaho ya HART mugihe uhuye no gukurikirana no kwerekana kurubuga, kugirango ufate amajwi, uhindure, kandi ugenzure;irashobora gukoreshwa cyane mu nganda z’imiti, kurengera ibidukikije, n’inganda z’imyenda., metallurgie, ubucukuzi bw'amabuye y'agaciro, ubuvuzi, gukora impapuro, gutanga amazi, ibiryo, isukari, inzoga n’izindi nganda zo gupima umuvuduko w’amazi y’ibitangazamakuru bitwara imiyoboro;usibye gupima ibintu rusange byamazi, ukurikije ibyifuzo byihariye byabakoresha, irashobora kandi gupima amazi yimyanda-ikomeye yibyiciro bibiri, gutembera kwamazi menshi yijimye hamwe namazi nkumunyu, acide ikomeye, na alkalis ikomeye.

Imiterere

(1) Sensor:

Rukuruzi igizwe ahanini na catheter yo gupima, electrode yo gupima, igiceri gishimishije, icyuma, icyuma, inzu.

Gupima umuyoboro: Igizwe n'umuyoboro w'icyuma udafite ingese, umurongo uhuza kandi uhuza flange, kandi niwo mutwara wo gupima aho amazi agomba gupimirwa.

Gupima electrode: couple ya electrode yashyizwe kurukuta rwimbere rwumuyoboro wapimye, perpendicular yerekeza kumyerekezo ya axial, kuburyo amazi yo gupima atanga ibimenyetso.

Igiceri cyo kwishima: Igiceri cyo hejuru no hepfo cyibyishimo bitanga umurongo wa magneti muri catheter yo gupima.

Ibyuma byuma na magnetisme: Umwanya wa magneti ukorwa na coil yo kwishima winjizwa mumazi kandi ugakora uruziga.

Igikonoshwa: gupakira hanze igikoresho.

(2) Guhindura:

Ni metero ya kabiri yubwenge, yongerera ibimenyetso byerekana kandi ikayibara hamwe na mudasobwa imwe ya chip kugirango yerekane urujya n'uruza rwinshi, kandi irashobora gusohora pulse, igereranya n’ibindi bimenyetso byo gupima cyangwa kugenzura imigendekere y’amazi.

(3) Ifishi yo guteranya ibicuruzwa:

Igabanijwemo uburyo bubiri: ubwoko bwahujwe nubwoko butandukanye.

Ubwoko bwahujwe: Rukuruzi hamwe nuhindura byashyizwe mugice kimwe.

Ubwoko bwa split: sensor hamwe nuhindura byashyizweho bitandukanye, kandi sisitemu yo gupima ibintu ikorwa muguhuza insinga.Kugirango wuzuze ibisabwa byo gupima itangazamakuru ritandukanye, ibikoresho bya electrode nibikoresho bya sensor birashobora kugira amahitamo menshi.

Ihame ry'akazi

Ihame ryakazi rya electromagnetic flowmeter rishingiye kumategeko ya Faraday yo kwinjiza amashanyarazi.Nukuvuga ko, mugihe amazi yimyanda atembera mumashanyarazi ya electronique, ingufu za electromotive zizabyara mumashanyarazi.Imbaraga zikoreshwa na electromotive ziragereranywa nigipimo cyogutemba kwamazi yimyanda, ubukana bwa magnetique, nubugari bwumuyoboro (diameter y'imbere ya fluxmeter), nkuko bigaragara ku gishushanyo.

Imbaraga zikoresha amashanyarazi zimenyekana hamwe na electrode ebyiri kurukuta rwa fluxmeter, kandi umuvuduko wikigereranyo urashobora kuboneka ukoresheje kubara.

Imbaraga za electromotive imbaraga zingana ni: E = KBVD

Muri formula: E yatewe imbaraga;D gupima umuyoboro w'imbere;

B ubukana bwa magnetique;V umuvuduko ugereranije;

K ni coefficient ijyanye no gukwirakwiza magnetiki ikwirakwizwa n'uburebure bwa axial.
