Ungayikhetha njani imitha yokuhamba kwe-electromagnetic?

I-fluid electromagnetic flowmeter yi-induction meter esekelwe kumthetho kaFarrah wokungenisa i-electromagnetic ukulinganisa ukuhamba komthamo we-conductive medium kumbhobho, esetyenziselwa ukulinganisa ukuhamba komthamo wolwelo oluqhubayo kumbhobho, njengamanzi, amanzi amdaka, udaka, i-pulp, i-asidi, i-alkali, ulwelo lwetyuwa kunye ne-food slurry. Isetyenziswa kakhulu kwi-petrochemical, kwimigodi nakwi-metallurgy, kumalahle, kubonelelo lwamanzi kunye nokutsalwa kwamanzi, kunyango lwamanzi amdaka nakwamanye amashishini.

Ngelixa idibana nomboniso okwindawo, imveliso inokukhupha isignali yangoku ye-4 ~ 20mA yokurekhoda, ukulawula nokulawula i-flowmeter ye-electromagnetic ukongeza ekulinganiseni ukuhamba kolwelo oluqhubayo ngokubanzi, inokulinganisa nokuhamba kolwelo oluqinileyo lwezigaba ezimbini, ukuhamba kolwelo olune-viscosity ephezulu kunye nokuhamba komthamo wetyuwa, i-asidi enamandla kunye nolwelo oluqinileyo lwe-alkali.

I-flowmeter ye-electromagnetic engamanzi ingabhekisa kumanqaku aliqela xa uthenga:

1, ngokweempawu zohlobo olunye kunye nohlobo olwahlukileyo lwe-electromagnetic flowmeter, khetha uhlobo olufanelekileyo. Umgca wokufakela uhlobo lomzimba ulula, ukuchaneka okuphakathi, akufuneki kufakwe ngaphantsi komhlaba, ukuthintela ukuba i-converter ingakhukuliswa ngamanzi. Uhlobo lokwahlula lwe-flowmeter luchaneke kakhulu, kwaye i-converter kunye ne-sensor zifakwe kwiindawo ezahlukeneyo, ezifanelekileyo ngakumbi kwiimeko apho imeko yentsimi imbi khona, kodwa ukufakwa kunye nokubekwa komgca kungqongqo, kungenjalo kulula ukungenisa imiqondiso yokuphazamiseka.

2, khetha uhlobo olufanelekileyo lwe-electrode. Kwisixhobo esingenzi i-crystallization, scarring, kunye ne-non-daining electrodes, ii-electrode eziqhelekileyo zingasetyenziswa, kwaye ii-electrode ezitshintshanayo nazo zingasetyenziselwa amaxesha okulinganisa udaka.

3. Khetha izinto ze-electrode ngokwendlela ezirhwaqelisayo ngayo izinto ezisetyenziswa xa zilinganiswa.

4, ngokwemeko yokugqwala, ukuguguleka kunye nobushushu besixhobo esilinganisiweyo ukukhetha izinto ze-lining.

5. Inqanaba lokhuseleko.

7, ngokwexinzelelo lesixhobo esilinganisiweyo ukukhetha uxinzelelo oluqhelekileyo lwesixhobo. Kwixinzelelo eliphakathi le-10MPa, 16MPa, 25MPa, 32MPa, kufuneka kukhethwe imitha yokuhamba kwamanzi yoxinzelelo oluphezulu.
