Ulwelo lwe-electromagnetic flowmeter yimitha yokungenisa esekwe kumthetho kaFarrah we-electromagnetic induction ukulinganisa ukuhamba komthamo we-conductive medium kumbhobho, osetyenziselwa ukulinganisa umthamo wokuhamba kolwelo oluqhubayo kumbhobho, njengamanzi, ugutyulo, udaka, ipulp. , iasidi, ialkali, ulwelo lwetyuwa kunye nodaka lokutya.Isetyenziswa kakhulu kwi-petrochemical, imigodi kunye ne-metallurgy, amalahle, unikezelo lwamanzi kunye ne-drainage, ukucocwa kogutyulo kunye namanye amashishini.
Ngelixa udibana nomboniso okwindawo, imveliso inokukhupha i-4 ~ 20mA isiginali yangoku yokurekhoda, ukulawula nokulawula i-electromagnetic flowmeter ukongeza kumlinganiselo wokuhamba kolwelo oluqhubayo ngokubanzi, inokulinganisa ukuqukuqela kolwelo oluqinileyo lwamanqanaba amabini, ukuhamba kwe-viscosity ephezulu yolwelo kunye nokuhamba komthamo wetyuwa, i-asidi eyomeleleyo kunye nolwelo oluqinileyo lwealkali.
Ulwelo lwe-electromagnetic flowmeter inokubhekisa kumanqaku aliqela xa uthenga:
1, ngokweempawu zohlobo olunye kunye nohlobo olwahlukileyo lwe-electromagnetic flowmeter, khetha uhlobo oluchanekileyo.Umgca wokufakelwa kohlobo lomzimba ulungele, ukuchaneka okuphakathi, akufanele kufakwe ngaphantsi komhlaba, ukukhusela umguquleli ukuba angakhukula.Uhlobo lokuhlukana kwe-flowmeter inokuchaneka okuphezulu, kwaye i-converter kunye ne-sensor ifakwe kwiindawo ezahlukeneyo, ezifanelekileyo ngakumbi kwizihlandlo apho indawo yentsimi ihlwempuzekileyo, kodwa ukufakela kunye nokubekwa komgca kungqongqo, ngaphandle koko kulula. ukwazisa imiqondiso yokuphazamiseka.
2, khetha ifom ye-electrode efanelekileyo.Kwi-medium engavelisi icrystallization, scarring, and non-staining electrode, i-electrodes eqhelekileyo ingasetyenziswa, kunye ne-electrode eguquguqukayo ingasetyenziselwa iziganeko zokulinganisa udaka.
3. Khetha izinto ze-electrode ngokwe-corrosiveness medium medium.
I-4, ngokwe-corrosion, ukunxiba kunye nobushushu be-medium medium to select the lining material.
5. Inqanaba lokhuseleko.
I-7, ngokoxinzelelo lwe-medium medium to select the nominal pressure of the equipment.Kuxinzelelo oluphakathi lwe-10MPa, 16MPa, 25MPa, 32MPa amanqanaba amaninzi omlinganiselo wokuqukuqela, i-electromagnetic flowmeter kufuneka ikhethwe.
