Iimfuno zofakelo lwe-electromagnetic flowmeter ezikrelekrele ukuchazwa okusemgangathweni

Ngophuhliso lwesayensi kunye netekhnoloji, ii-flowmeters ze-electromagnetic ziye zandiswa ngokuthe ngcembe kwindawo yokulinganisa ukuhamba.Njengomlinganiselo obalulekileyo wokuhamba, ukuchaneka kwayo kudlala indima ebalulekileyo ekulawuleni umgangatho wenkqubo yokuvelisa.Kusetyenziso lwexesha lokuhamba kwe-electromagnetic, ikhonkco lokufakela likwabalulekile.Oku kulandelayo yimilinganiselo esisiseko yokufakelwa kwee-flowmeters ezikrelekrele ze-electromagnetic:

1. Ukufakwa kwe-electromagnetic flowmeter kufuneka kuqinisekise ukuba umbhobho wayo wokulinganisa ufakwe ngokuthe tye kwaye umgodi wangaphakathi uzinzile.Ngethuba lesigaba sofakelo, isalathiso esithe tye kunye nesithambekileyo sombhobho wokulinganisa kufuneka sizimisele ukuqinisekisa ukuba i-electromagnetic flowmeter i-perpendicular kwindiza yombhobho.

2. Ngethuba lofakelo, ingqalelo ekhethekileyo kufuneka ihlawulwe kwi-flatness kunye ne-curvature yombhobho.Kwicandelo lombhobho ochanekileyo, i-crossover, ukugoba kunye nokufakwa kufuneka kugwenywe.

3. Xa ufaka i-electromagnetic flow meter, qinisekisa ukuba ubude becandelo lombhobho othe nkqo abukho ngaphantsi kwamaxesha ali-10 kwidayamitha ye-electrode, kwaye uqinisekise ukuba ubude becandelo lombhobho othe nkqo abukho ngaphantsi kwamaxesha angama-20 edayamitha ye-electrode xa ugoba. umbhobho okanye umahluko we-perpendicularity mkhulu.

4. Indawo yofakelo lwe-electromagnetic flowmeter kumbhobho kufuneka iqinisekise ukuba ufakelo luzinzile, akufuneki kubekho ntshukumo yangaphandle okanye impembelelo, kwaye indawo yofakelo ayinakuba kwindawo yokugoba yombhobho ukunqanda iimpazamo zomlinganiso ngenxa yobuninzi. ukugoba.

5, kufakelo lwexesha lokuhamba kwe-electromagnetic, kufuneka ukhethe imitha yokuhamba ngokuhambelana nobubanzi bombhobho, akufuneki ube mkhulu kakhulu okanye ube mncinci kakhulu.Kwangaxeshanye, kuyafuneka ukuba ukhethe iplagi-in okanye i-immersion electromagnetic flowmeter ngokufanelekileyo ngokweemeko zentsimi.

6. Emva kofakelo, i-electromagnetic flowmeter kufuneka ilinganiswe ukuqinisekisa ukuchaneka kwayo.Ukusetwa kwangoku kunye nokulungelelaniswa kwe-conductivity kufuneka kuthathelwe ingqalelo kwangexesha esikolweni.

7. I-electromagnetic flowmeter kufuneka igcinwe rhoqo ngexesha lokusetyenziswa, kwaye i-electrode kunye nezikhundla zenzwa kufuneka ziqinisekiswe ukuba zicocekile kwaye azinangxaki.

Ngamafutshane, ekusetyenzisweni kwexesha lokuhamba kwe-electromagnetic kufuneka ifakwe ngokungqongqo kwaye igcinwe ngokuhambelana neemfuno zokuqinisekisa ukuchaneka kwayo, ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.
