Ukukhethwa Kwama-Electrode Kwamamitha Okugeleza Kwama-Electromagnetic

Amamitha okugeleza kagesi (aziwa nangokuthi ama-mag meter) asetshenziswa kabanzi ekulinganiseni ukugeleza koketshezi oluqhubayo ezisetshenziswa ezimbonini. Asebenza ngokusekelwe kuMthetho kaFaraday wokungeniswa kwe-electromagnetic futhi awanazo izingxenye ezihambayo, okwenza abe anembe kakhulu futhi athembeke emisebenzini ehlukahlukene yokulinganisa ukugeleza. Ingxenye ebalulekile yamamitha okugeleza kagesi yi-electrode, edlala indima ebalulekile enkambisweni yokulinganisa. Ukukhethwa kwezinto ze-electrode kanye nokucushwa kuncike ezintweni eziningana, njengoketshezi olulinganiswayo, izimo zemvelo, kanye nokunemba kokulinganisa okufiswayo.

Izinto Ezibalulekile Okufanele Uzicabangele Ngokukhetha Ama-Electrode

1. Ukuqhuba Koketshezi

Amamitha okugeleza kagesi adinga ukuthi uketshezi lukwazi ukuqondisa ugesi ukuze isilinganiso sokugeleza sisebenze kahle. Ama-electrode abona i-voltage ekhiqizwayo lapho uketshezi ludlula ensimini yamagnetic yemitha yokugeleza. Ngakho-ke, ukukhetha izinto ze-electrode ezifanele kubalulekile ukuqinisekisa ukulinganisa okunembile, ikakhulukazi uma ukuqondisa koketshezi kuphansi noma kuphezulu.

2. Izinto ze-Electrode

Izinto ezisetshenziswa kuma-electrode kumele zihambisane nezakhiwo zamakhemikhali zoketshezi ukuqinisekisa ukuqina nokuthembeka. Izinto ezivamile zama-electrode zifaka:

• Insimbi Engagqwali (316L):Enye yezinto ezisetshenziswa kakhulu kuma-electrode, insimbi engagqwali inikeza ukumelana okuhle kakhulu nokugqwala futhi ifaneleka ezinhlobonhlobo zoketshezi, okuhlanganisa amanzi, ama-slurry, kanye namakhemikhali amaningi.

• I-Hastelloy (HC276):I-Hastelloy iyi-alloy engagqwali, eyaziwa kakhulu ngekhono layo lokubekezelela amakhemikhali aqinile kanye nokushisa okukhulu.HC276ivame ukusetshenziswa ezimbonini ezifana nemithi, amakhemikhali, kanye nokucubungula ukudla, lapho ukuchayeka kuma-asidi anamandla, ama-alkali, kanye nezinyibilikisi kuvame khona. Inikeza ukumelana okuphezulu kokugqwala futhi ifaneleka kakhulu ezindaweni ezinomfutho ophezulu kanye nezinokushisa okuphezulu.

• I-Titanium (Ta):Ama-electrode e-titanium amelana kakhulu nokugqwala futhi afaneleka kakhulu ezindaweni ezinzima, ikakhulukazi lezo ezifaka amanzi olwandle, ama-asidi, nezinye izinto ezigqwala kakhulu. I-Tantalum (Ta) ingenye into efanayo enezakhiwo ezivelele zokumelana nokugqwala, ikakhulukazi eziketshezini ezine-asidi nezisabela kakhulu. I-Tantalum ibaluleke kakhulu lapho ibhekene nama-asidi aqinile, okuhlanganisa i-sulfuric acid, i-hydrochloric acid, nezinye izinto ezigqwala kakhulu.

• Iplatinum (Pt):I-Platinum imelana kakhulu nokugqwala kwamakhemikhali, okwenza ifanelekele uketshezi olunamandla kakhulu, kodwa ivame ukusetshenziswa ezicelweni ezikhethekile ngenxa yezindleko zayo eziphakeme. Ama-electrode e-Platinum ayathandwa ezindaweni lapho kudingeka khona ukunemba okukhulu kanye nokungangeni kwamakhemikhali, njengasezinhlelweni zelebhu noma kwezinye izinhlelo zokusebenza zezokwelapha nezokuhlaziya. Ukuqina okuhle kakhulu kwe-Platinum kanye nokumelana namakhemikhali ahlukahlukene kwenza kube kuhle kakhulu ezicelweni ezidinga ukusebenza njalo.

• I-Graphite noma i-Carbon:Lezi zinto ngezinye izikhathi zisetshenziselwa izinhlelo zokusebenza ezihlanganisa uketshezi olunamandla kakhulu noma olunamandla. Ama-electrode e-graphite nawo amelana kakhulu nokugqwala kodwa angase aguge ngaphansi kwezimo ezithile.

• Igolide:Ama-electrode egolide avame ukusetshenziswa ezimweni ezidinga ukunemba okuphezulu kakhulu futhi avame ukutholakala elabhorethri noma ezicelweni ezikhethekile kakhulu.

3. Ukucushwa kwe-Electrode

Ukucushwa kwe-electrode kungathinta ukunemba kanye nokuzwela kwemitha yokugeleza. Ukucushwa kwe-electrode okuvame kakhulu okubili yile:

• Ukucushwa kwe-Electrode eyodwa:Lokhu kulungiselelwa kuhilela i-electrode eyodwa yokuxhumana koketshezi kanye nenye yesignali yokubhekisela. Kulula futhi kuyabiza kakhulu kodwa kunganikeza ukunemba okuphansi kwezinye izinhlelo zokusebenza.

• Ukucushwa Kwama-Electrode Amaningi (Ama-Electrode Amane):Lo mklamo uhlanganisa ama-electrode amaningi ahlelwe ngephethini eliyindilinga elizungeze ipayipi. Lokhu kulungiselelwa kunikeza izilinganiso ezinembile, ikakhulukazi ekusetshenzisweni okune-fluid eqine kakhulu noma eyinkimbinkimbi. Kungasiza futhi ekunciphiseni amaphutha ngenxa ye-polarization kanye nokuphazamiseka kwesignali.

4. Ukugqoka Nokuvikela Ama-Electrode

Kwezinye izimo, ama-electrode angase ambozwe noma avikelwe ukuze kuthuthukiswe ukusebenza kwezinhlelo ezithile. Isibonelo:

• Izembozo ze-Ceramic:Kuketshezi oluqothulayo noma oluqothulayo kakhulu, izembozo ze-ceramic zingasiza ekuvikeleni ama-electrode ekulimaleni futhi zandise isikhathi sawo sokuphila.

• Izembozo ze-PTFE noma ze-PFA:Kumakhemikhali angahambisi ugesi noma anamandla, izembozo ze-electrode ezenziwe ngama-fluoropolymers njenge-PTFE noma i-PFA zisetshenziselwa ukuhlinzeka ngokuvikela nokuvikela.

5. Ukumelana Nokushisa Nokucindezela

Ama-electrode kufanele akhethwe ngokusekelwe ezimweni zokushisa kanye nengcindezi zesicelo. Isibonelo, ama-electrode e-titanium, i-Hastelloy, kanye ne-platinum afaneleka kangcono ekusetshenzisweni kwezinga lokushisa eliphezulu kanye nengcindezi ephezulu uma kuqhathaniswa nama-electrode ensimbi engagqwali ajwayelekile.

6. Usayizi weMitha Yokugeleza kanye Nokusetshenziswa

Usayizi kanye nohlobo lwemitha yokugeleza kagesi (isb., i-full-bore noma i-insertion) kuzothinta nokukhethwa kwe-electrode. Amamitha okugeleza amakhulu ngokuvamile adinga ama-electrode amakhulu ukuze asebenze kahle.

Isiphetho

Ukukhethwa kwama-electrode kwamamitha okugeleza kagesi kubalulekile ukuqinisekisa ukulinganiswa okunembile kokugeleza, ikakhulukazi ezindaweni zezimboni eziyinselele. Ngokucabangela ukuqhutshwa koketshezi, izakhiwo zezinto zama-electrode, ukuhlelwa kwama-electrode, kanye nezimo zokusebenza (njengokushisa, ingcindezi, kanye nokuchayeka kwamakhemikhali), ungakhetha izinto ezifanele ze-electrode kanye nokuhlelwa kohlelo lwakho lokusebenza. Izinto ezifana ne-HC276 (Hastelloy), i-Ta (Tantalum), kanye ne-Pt (Platinum) zinikeza ukumelana okuhle kakhulu nokugqwala futhi zifaneleka kakhulu ekusetshenzisweni okudinga amandla. Ukukhethwa kwama-electrode okufanele kungathuthukisa ubude besikhathi kanye nokuthembeka kwemitha yokugeleza, okwenza kube yimpahla ebalulekile ezinhlelweni zokulinganisa ukugeleza kwezimboni.
