Ukuqonda Izinto Zokugquma I-Lining kwi-Electromagnetic Flow Meters

Iimitha zokuhamba kwe-electromagnetic(ezaziwa ngokuba ziimitha ze-mag) zisetyenziswa kakhulu kumashishini ahlukeneyo ukulinganisa ukuhamba kolwelo oluqhubayo. Ezi mitha ze-flow zisebenza ngokusekelwe kuMthetho kaFaraday wokungeniswa kwe-electromagnetic, ongadingi nxalenye ishukumayo, obonelela ngokuchaneka okuphezulu kunye nokuthembeka ekulinganisweni kokuhamba kolwelo. Elinye icandelo elibalulekileyo lemitha ye-flow ye-electromagnetic zizinto ze-lining, ezisebenza ukukhusela umphezulu wangaphakathi wemitha ngelixa ziqinisekisa ukusebenza ngokufanelekileyo kwesixhobo. Ukukhethwa kwezinto ze-lining kuchaphazela ngokuthe ngqo ukusebenza, ukuqina, kunye nokufaneleka kwemitha ye-flow kwizicelo ezahlukeneyo. Kweli nqaku, siza kuhlola izinto ezahlukeneyo ze-lining ezisetyenziswa kwiimitha ze-flow ye-electromagnetic kunye nendlela ezichaphazela ngayo ukusebenza kwemitha.

Zithini Izinto Zokufaka IlayiniIimitha zokuhamba kwe-electromagnetic?

Izinto zokubopha ilayini zisetyenziselwa ukugquma umphezulu ongaphakathi wetyhubhu yemitha yokuhamba kwamanzi ukukhusela imitha kwiikhemikhali ezirhabaxa, ukukrweleka, kunye nobushushu obugqithisileyo. Izinto zokubopha ilayini ezifanelekileyo ziqinisekisa ukulinganiswa okuchanekileyo ngelixa zandisa ubomi bemitha ngokuthintela umonakalo ovela kulwelo olunobuthi okanye iimeko zokusebenza ezinzima.

Izinto Ezibalulekileyo Zokukhetha Izinto Zokugquma Ilayini

Xa ukhetha izinto zokudibanisa i-lining kwi-electromagnetic flow meter, kufuneka kuqwalaselwe izinto ezininzi:

• Ukumelana neekhemikhali: Le nto kufuneka imelane nolwelo olulinganiswayo, ingakumbi kwiindawo ezineekhemikhali okanye iiasidi ezirhabaxa.
• Ukumelana nokurhawuzelelwa: Ukuba ulwelo lunamasuntswana aqinileyo okanye amaqhekeza aqinileyo, kufuneka into enokumelana nokukrweleka okuphezulu.
• Ukumelana nobushushu: Izinto ezifakwe ngaphakathi kufuneka zikwazi ukumelana namaqondo obushushu okusebenza kwesicelo.
• Ukuhambelana kolwelo: Ingaphakathi kufuneka lihambelane nohlobo lolwelo olulinganiswayo, nokuba lurhabaxa kakhulu, lurhabaxa, okanye lunoxinzelelo oluphezulu.
