Ukufakwa kwesisekelo esifanele kuyingxenye ebalulekile yokufakwa kwemitha yokugeleza kagesi. Njengoba imitha yokugeleza kagesi ilinganisa isignali kagesi encane kakhulu ekhiqizwa ukunyakaza koketshezi oluqhubayo ensimini yamagnetic, ukuphazamiseka kukagesi kwangaphandle noma amandla okubhekisela angazinzile kungathinta ukuzinza kokulinganisa.
Amasongo okumisa kanye nama-electrode okumisa asetshenziswa ukuqinisekisa ukuthi uketshezi, umzimba wesenzwa, kanye nepayipi kunamandla kagesi afanayo, okunikeza ireferensi yokulinganisa ezinzile kanye nokunciphisa umsindo wesiginali.
Kungani Kudingeka Ukufaka Inhlabathi Ku-Electromagnetic Flow Meter?
Imitha yokugeleza kagesi isebenza ngokusekelwe kuMthetho kaFaraday Wokungeniswa Kwe-Electromagnetic. Ngesikhathi sokulinganisa, isignali ye-voltage ekhiqizwa phakathi kwama-electrode ivame ukuba yincane kakhulu, ngokuvamile ama-millivolt ambalwa kuphela.
Ngenxa yokuthi isignali yokulinganisa ibucayi kakhulu, amamitha okugeleza kagesi angathinteka yilokhu:
* Amaza kagesi alahlekile epayipini
* Umsindo kagesi ovela kuma-motor noma kuma-frequency converters
* Izimo ezimbi zokubeka phansi
* Izinto zombhobho ezingahambisi ugesi
* Izinhlelo zokuvikela i-Cathodic
Ngaphandle kokufakwa kahle kwesisekelo, isignali yokugeleza ingase ingazinzile, okubangela:
* Ukuguquguquka kokubonisa ukugeleza
* Iphuzu lika-zero elingalungile
* Amaphutha okulinganisa
* Izimpawu zokukhipha ezingazinzile
Ngakho-ke, uhlelo lokusekela oluthembekile lubalulekile ukuze kusebenze kahle futhi kuzinzile.
Kufanele Kufakwe Kuphi Izindandatho Zokumisa?
Izindandatho zokumisa inhlabathi zivame ukufakwa phakathi kwe-flange yemitha yokugeleza kanye ne-flange yephayiphi.
Indandatho yokumisa kufanele ibekwe ngendlela yokuthi ixhumane ngqo noketshezi oluqhubayo futhi ixhunywe ngogesi endaweni yokumisa imitha yokugeleza.
Inqubo yokufaka evamile yile:
1. Beka indandatho yokumisa phakathi kwe-flange yenzwa kanye ne-flange yepayipi.
2. Qinisekisa ukuthi i-gasket yokuvala ayimbozi ubuso bendandatho yokumisa ethinta uketshezi.
3. Xhuma indandatho yokumisa phansi esiphelweni sokumisa phansi esisemitha yokugeleza kagesi usebenzisa ucingo lokumisa phansi.
4. Xhuma uhlelo endaweni ethembekile yokumisa umhlaba.
Kunini Lapho Kudingeka Izindandatho Zokumisa Inhlabathi?
Izindandatho zokumisa zinconywa kakhulu ezimweni ezilandelayo:
1. Amapayipi Angaqhubi Umoya
Uma ipayipi lenziwe ngezinto ezifana nalezi:
* I-PVC
* I-PP
* Ipayipi elinezintambo ze-PTFE
* Ipayipi elinophahla lwerabha
* Ipulasitiki eqiniswe nge-fiberglass (FRP)
ipayipi ngokwalo alikwazi ukunikeza uxhumano lukagesi oluthembekile.
Kulezi zimo, izindandatho zokufaka isisekelo ziyadingeka ukuze kusungulwe ireferensi kagesi eqinile phakathi koketshezi kanye nemitha yokugeleza.
2. Izicelo Zepayipi Lepulasitiki
Amapayipi epulasitiki avame ukusetshenziswa ekuhlanzweni kwamanzi, ekucutshungulweni kwamakhemikhali, kanye nasekusetshenzisweni kwezimboni.
Ngenxa yokuthi izinto zepulasitiki ziyizivikeli zikagesi, uketshezi olungaphakathi kwepayipi lungase luhlukaniswe ngogesi nenzwa. Ukufaka izindandatho zokusekela kusiza ekuqedeni le nkinga.
3. Izicelo Ezineziphazamiso Zikagesi
Ezindaweni zezimboni ezine:
* Izimoto ezinkulu
* Amaphampu
* Ama-drive e-frequency aguquguqukayo (i-VFD)
* Imishini yokushisela
Izindandatho zokusekela zingasiza ekunciphiseni ukuphazamiseka kukagesi futhi zithuthukise ukuzinza kokulinganisa.
Kufanele Kufakwe Kuphi Ama-Electrode Okusekela Inhlabathi?
Ama-electrode aphansi avame ukufakwa ngqo emzimbeni wesenzwa yemitha yokugeleza kagesi.
Zenzelwe ukunikeza ireferensi kagesi eqinile phakathi koketshezi kanye nenzwa.
Kuye ngomklamo wemitha yokugeleza, ama-electrode aphansi angaba:
* Yakhelwe emzimbeni wesenzwa.
* Kufakwe njengezingxenye ezihlukene zokumisa phansi.
* Kuhlanganiswe nama-electrode okubhekisela kuwo.
Ama-electrode aphansi kufanele atholakale ethintana noketshezi lwenqubo futhi axhunywe ngaphakathi noma ngaphandle ngokwedizayini yomenzi.
Umehluko Phakathi Kwezindandatho Zokumisa kanye Nama-Electrode Okumisa
Izindandatho zokumisa kanye nama-electrode okumisa kufeza izinhloso ezifanayo kodwa zisetshenziswa ezimweni ezahlukene.
Ama-electrode aphansi ngokuvamile ayingxenye yenzwa yemitha yokugeleza futhi ahlinzeka nge-reference potential ngqo evela kuketshezi.
Izindandatho zokumisa inhlabathi ziyizesekeli ezengeziwe ezifakwe phakathi kwemitha yokugeleza kanye nepayipi, ezisetshenziswa kakhulu lapho ipayipi lingakwazi ukunikeza isisekelo esifanele.
Ezinhlelweni eziningi zepayipi lensimbi ezijwayelekile, ama-electrode okufaka umhlabathi angase abe anele kakade. Kodwa-ke, kumapayipi epulasitiki noma amapayipi anezinsika, izindandatho zokufaka umhlabathi zivame ukunconywa.
Izincomo Zokufaka Zokumisa Inhlabathi
Ukuze ufinyelele ukusebenza okuthembekile kokulinganisa, landela lezi ziqondiso:
1. Sebenzisa Uxhumano Oluzinikele Lokusekela
Imitha yokugeleza kufanele ixhunywe emhlabathini othembekile kusetshenziswa ikhebula elifanele lokufaka ugesi.
Ungathembeli ku:
* Ukusekelwa kwephayiphi
* Ama-Flanges kuphela
* Izakhiwo zensimbi eziseduze
njengendlela yokumisa umhlaba.
2. Gcina Ukumelana Nokumisa Inhlabathi Kuphansi
Ukuxhumeka komhlabathi kufanele kube nokumelana okuphansi kukagesi ukuze kuhlinzekwe amandla okubhekisela azinzile.
Ukungafakwa kahle kwenhlabathi kungabangela:
* Ukuguquguquka kwesignali
* Ukungazinzi komphumela
* Ukuphazamiseka kokuxhumana
3. Gwema Ukwabelana Ngokumisa Inhlabathi Ngemishini Enamandla Aphezulu
Uhlelo lokufaka isisekelo semitha yokugeleza kufanele lugweme ukwabelana ngendawo efanayo yokufaka isisekelo nemishini edala umsindo kagesi, njengalokhu:
* Ama-motor
* Ama-Inverter
* Imishini yokushisela
Indawo ehlukile yokumisa inhlabathi iyathandwa ezindaweni zezimboni.

4. Naka Amapayipi Avikelwe Ngokwe-Cathodically
Amanye amapayipi asebenzisa izinhlelo zokuvikela i-cathodic ukuvimbela ukugqwala.
Kulezi zinhlelo zokusebenza, ukuxhumana okuqondile kwesisekelo kungadala izindlela zamanje ezingafuneki futhi kuthinte ukunemba kokulinganisa.
Kungadingeka izindlela ezikhethekile zokufaka, njengokuhlukaniswa kukagesi phakathi kwemitha yokugeleza kanye nohlelo lokufaka ipayipi phansi.
Ukwakha Isisekelo Sezinto Ezihlukahlukene Zepayipi
Kwamapayipi ensimbi:
* Ipayipi livame ukunikeza ukuqhubeka okuhle kukagesi.
* Ama-electrode aphansi anganelisa uma ipayipi liphansi kahle.
Kwamapayipi epulasitiki:
* Kunconywa kakhulu ukuthi kufakwe izindandatho zokumisa.
* Imitha yokugeleza ayikwazi ukuthembela epayipini ukuze ibhekisele kugesi.
Kwamapayipi anemigqa:
* Hlola ukuthi izinto zokwemboza zivikela ngogesi yini.
* Sebenzisa izindandatho zokumisa uma uketshezi lukhishwe ngogesi epayipini.
Izinkinga Ezivamile Zesisekelo Nezixazululo
Inkinga: Isignali yokugeleza iyashintshashintsha ngemva kokufakwa
Izimbangela ezingaba khona:
* Ukuxhumeka okungekuhle kwesisekelo
* Ukuphazamiseka kukagesi
* Azikho izindandatho zokufaka isisekelo ezifakiwe kumapayipi okuvikela umswakama
Isixazululo:

Amasongo okumisa kanye nama-electrode okumisa adlala indima ebalulekile ekuqinisekiseni ukulinganiswa kokugeleza kwe-electromagnetic okunembile nokuzinzile.
Ama-electrode aphansi avame ukufakwa ku-sensor ye-flow meter ukuze anikeze amandla okubhekisela ngqo kusuka kuketshezi. Amasongo aphansi afakwa phakathi kwe-flow meter flange kanye ne-pipeline flange, ikakhulukazi uma kusetshenziswa amapayipi angahambisani nogesi noma lapho kudingeka isivikelo esengeziwe somhlaba.
Ukubeka phansi okulungile kusiza ekunciphiseni ukuphazamiseka kukagesi, ukuzinzisa izimpawu zokulinganisa, nokuqinisekisa ukusebenza okuthembekile kwesikhathi eside kwamamitha okugeleza kagesi.
