Kwizixhobo zesivamvo ze-elektroniki, umgaqo wokulinganisa we-electromagnetic flowmeter ngumthetho kaFaraday wokungeniswa kombane.Ubume be-electromagnetic flowmeter ikakhulu yenziwe yinkqubo yesekethe yemagnethi, i-conduit yokulinganisa, i-electrode, iqokobhe, i-lining kunye nesiguquli.Ikakhulu isetyenziselwa ukulinganisa ukuhamba kwevolumu ye-conductive liquids kunye ne-slurries kwimibhobho evaliweyo.Kubandakanya iiasidi, iialkali, iityuwa kunye nolunye ulwelo olunokutya okugqwesileyo.Le mveliso isetyenziswa kakhulu kwi-petroleum, ikhemikhali, isinyithi, i-textile, ukutya, i-pharmaceutical, i-papermaking kunye namanye amashishini, kunye nokukhuselwa kwendalo, ulawulo lukamasipala, ukwakhiwa kokugcinwa kwamanzi kunye nezinye iindawo.
Kwinkqubo yokusebenzisa i-electromagnetic flowmeter, ezinye iintsilelo zezixhobo ziya kwenzeka ngokuqinisekileyo.Ngokuqhelekileyo kukho iindidi ezimbini zokungaphumeleli ekusebenzeni: enye kukungaphumeleli kwesixhobo ngokwaso, oko kukuthi, ukungaphumeleli okubangelwa ngumonakalo kwiindawo zesakhiwo okanye amacandelo esixhobo;okwesibini, ukungaphumeleli okubangelwa yizizathu zangaphandle, ezifana nokufakwa okungafanelekanga, ukuphazamiseka kokuhamba, ukubekwa kunye nokulinganisa, njl.
Xa i-electromagnetic flowmeter isilela, sihlala kufuneka sihlalutye ukuba leliphi icandelo elinempazamo kwaye sifumanise ukuba siyilungisa njani ingxaki.
1. Iimpazamo eziqhelekileyo ze-electromagnetic flowmeter - i-electromagnetic flowmeter ayinayo i-flow signal output
Olu hlobo lokusilela luxhaphake kakhulu ngexesha lokusetyenziswa, kwaye izizathu ziqhelekile:
(1) Umbane wesixhobo awuqhelekanga;
(2) Uqhagamshelo lwentambo kunye nemveliso yebhodi yesekethe yamandla ayiqhelekanga;
(3) Ukuhamba kolwelo akuhlangabezani neemfuno zofakelo;
(4) Amacandelo enzwa wonakaliswe okanye kukho i-adhesive layer eludongeni lwangaphakathi lomlinganiselo;
(5) Amacandelo okuguqula ezonakalisiweyo
Indlela yokusombulula?
Ukuba oku kuyenzeka, jonga kuqala ukuba unikezelo lwamandla lwesixhobo lunempazamo, qinisekisa ukuba unikezelo lwamandla luqhagamshelwe, khangela ukuba umbane ophumayo webhodi yesekethe yonikezelo lombane uqhelekile, okanye uzame ukubuyisela yonke ibhodi yesekethe yonikezelo lwamandla ukugqiba. nokuba ilungile na.Khangela ukuba iintambo zicocekile kwaye ziqhagamshelwe ngokuchanekileyo.Khangela isikhokelo sokuhamba kolwelo kunye nolwelo olukumbhobho lugcwele.Ukuba akukho lulwelo kwi-sensor, kuya kufuneka utshintshe i-tubing okanye utshintshe indlela yokunyuka.Zama ukuyifaka ngokuthe nkqo.
2. Umqondiso we-electromagnetic flowmeter uya usiba mncinci kwaye uncinci okanye umqondiso wehla ngokukhawuleza
Uninzi lwezi ziphoso zibangelwa yimpembelelo yendlela yokulinganisa okanye indawo yangaphandle, kwaye iphoso inokupheliswa ngokwayo emva kokuphazamiseka kwangaphandle.Ukuze kuqinisekiswe ukuchaneka komlinganiselo, ukungaphumeleli okunjalo akunakunakwa.Kwezinye iindawo zokuvelisa, ngenxa yokunyakaza okukhulu kombhobho wokulinganisa okanye ulwelo, ibhodi yesekethe ye-flowmeter iya kukhululeka, kwaye ixabiso lokuphuma lingatshintsha.
Indlela yokusombulula?
(1) Qinisekisa ukuba sisizathu sokusebenza kwenkqubo, kwaye ulwelo luyabetha.Ngeli xesha, i-flowmeter ibonisa kuphela imeko yokuhamba ngokunyanisekileyo, kwaye iphoso inokupheliswa ngokwayo emva kokuphela kwe-pulsation.
(2) Ukuphazamiseka kwe-electromagnetic okubangelwa yimisinga yangaphandle elahlekileyo, njl.njl. Jonga ukuba kukho izixhobo zombane ezinkulu okanye oomatshini bokuwelda bombane abasebenza kwindawo yokusebenza yesixhobo, kwaye uqinisekise ukuba isixhobo sisekelwe phantsi kwaye indawo yokusebenza ilungile.
(3) Xa umbhobho ungazaliswanga ngolwelo okanye ulwelo lunamaqamza omoya, zombini zibangelwa zizizathu zenkqubo.Ngeli xesha, umchwephesha unokucelwa ukuba aqinisekise ukuba ixabiso lemveliso lingabuyela kwisiqhelo emva kokuba i-liquid igcwele okanye i-bubbles emoyeni iyancipha.
(4) Ibhodi yesiphaluka ye-transmitter yisakhiwo seplagi.Ngenxa yokushukuma okukhulu kombhobho wokulinganisa kwisiza okanye ulwelo, ibhodi yamandla ye-flowmeter isoloko ikhululiwe.Ukuba ikhululekile, i-flowmeter inokuchithwa kwaye ibhodi yesiphaluka inokulungiswa kwakhona.
3. Indawo enguziro ye-electromagnetic flowmeter ayizinzanga
Uhlalutyo lwesizathu
(1) Umbhobho awugcwaliswa ngolwelo okanye ulwelo lunamaqamza omoya.
(2) Ngokuxhomekeke, kukholelwa ukuba akukho mpompozo wolwelo kwimpompo yombhobho, kodwa ngokwenene kukho ukuhamba okuncinci.
(3) Izizathu zolwelo (ezifana nokungahambelani kakuhle kolwelo, ungcoliseko lwe-electrode, njl.).
(4) I-insulation ye-signal circuit iyancipha.
Indlela yokusombulula?
Kuyimfuneko ukujonga ukuba ngaba i-medium igcwele imibhobho kunye nokuba kukho iibhubhu zomoya phakathi.Ukuba kukho amaqamza omoya, i-aireliminator inokufakwa phezulu kumaqamza omoya.Ufakelo oluthe tyaba lwesixhobo lunokutshintshwa kwakhona kufakelo oluthe nkqo.Jonga ukuba isixhobo sisekelwe kakuhle na.Ukumelana nomhlaba kufuneka kube ngaphantsi okanye kulingane ne-100Ω;i-conductivity ye-conductive medium akufanele ibe ngaphantsi kwe-5μs / cm.Ukuba i-medium iqokelela kwi-tube yokulinganisa, kufuneka isuswe ngexesha.Kuphephe ukukrwela umgca xa ususa.
