Kumvetsetsa Zipangizo Zopangira Ma Lining za Ma Electromagnetic Flow Meters

Ma electromagnetic flow meter(yomwe imadziwikanso kuti mag meter) imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana poyesa kuyenda kwa madzi oyendera. Ma flow meter awa amagwira ntchito motsatira lamulo la Faraday la electromagnetic induction, lomwe silifuna magawo osuntha, kupereka kulondola kwakukulu komanso kudalirika pakuyeza kuyenda kwa madzi. Gawo limodzi lofunika kwambiri la electromagnetic flow meter ndi zinthu zamkati, zomwe zimateteza mkati mwa mita pomwe zikuwonetsetsa kuti chipangizocho chikugwira ntchito bwino. Kusankha zinthu zamkati kumakhudza mwachindunji magwiridwe antchito, kulimba, komanso kuyenerera kwa flow meter pa ntchito zosiyanasiyana. M'nkhaniyi, tifufuza zinthu zosiyanasiyana zamkati zomwe zimagwiritsidwa ntchito mu electromagnetic flow meter ndi momwe zimakhudzira ntchito ya mita.

Kodi Zipangizo Zomangira M'kati Zili ndi Chiyani?Ma Electromagnetic Flow Meters?

Zipangizo zomangira mkati zimagwiritsidwa ntchito kuphimba pamwamba pa chubu choyezera madzi kuti ziteteze mita ku mankhwala amphamvu, kukwawa, ndi kutentha kwambiri. Zipangizo zoyenera zomangira mkati zimatsimikizira kuyeza kolondola pamene zikuwonjezera nthawi ya moyo wa mita popewa kuwonongeka ndi madzi owononga kapena mikhalidwe yovuta yogwirira ntchito.

Zinthu Zofunika Kwambiri Posankha Zipangizo Zophimba M'kati

Posankha zinthu zomangira pa mita yoyendera magetsi, zinthu zingapo ziyenera kuganiziridwa:

• Kukana Mankhwala: Zinthuzo ziyenera kukhala zolimbana ndi madzi omwe akuyesedwa, makamaka m'malo okhala ndi mankhwala amphamvu kapena ma acid.
• Kukana Kumva KuwawaNgati madziwo ali ndi tinthu tolimba kapena matope, chinthu chomwe chimatha kuuma kwambiri ndi chofunikira.
• Kukana Kutentha: Chipinda cholumikizira chiyenera kupirira kutentha kwa ntchito.
• Kugwirizana kwa Madzimadzi: Chipindacho chiyenera kugwirizana ndi mtundu wa madzi omwe akuyesedwa, kaya ndi owononga kwambiri, okwirira, kapena opanikizika kwambiri.

Zipangizo Zodziwika Bwino Zopangira Ma Electromagnetic Flow Meters

Zipangizo Zomangira M'kati	Katundu	Mapulogalamu	Ubwino	Zoletsa
PTFE (Teflon)	Kukana kwambiri mankhwala ku zidulo, alkali, ndi zosungunulira zachilengedwe. Malo osalala, osamata.	Kukonza mankhwala, chakudya ndi zakumwa, mankhwala.	Kukana mankhwala kwambiri, pamwamba pake sipamata.	Kukana kukanda pang'ono, kutayika m'malo okhwimitsa.
Neoprene (Ne)	Yosinthasintha, yolimba ku mafuta, mafuta, ndi mankhwala ochepa.	Mafuta ndi gasi, magalimoto, ndi ntchito zamafakitale.	Yosinthasintha, yolimba ku mafuta ndi mafuta.	Kukana mankhwala pang'ono poyerekeza ndi zipangizo zapadera.
Neoprene Yolimbikitsidwa ndi Ulusi wa Galasi (GFNE)	Mphamvu ya makina, kutentha, ndi kukana mankhwala.	Kuchiza madzi, mafakitale amafuta, ntchito zamafakitale.	Mphamvu ya makina imakula, kukana mankhwala bwino.	Sizilimba kwambiri m'malo okhala ndi mankhwala amphamvu kwambiri.
Polyurethane (PU)	Yolimba kwambiri, yolimba kwambiri, yolimba kwambiri kukana kukwawa, yolimba bwino ku mafuta ndi zosungunulira zachilengedwe.	Kukumba, kukonza madzi otayira, kugwiritsa ntchito matope.	Kukana kwambiri kukanda, komwe ndi kwabwino kwambiri pa zinthu zokanda.	Kukana mankhwala pang'ono poyerekeza ndi PTFE ndi PFA.
Fluorinated Ethylene Propylene (FEP)	Kukana mankhwala bwino kwambiri, malo osalala, osakokana kwambiri.	Kukonza mankhwala, mafakitale opanga mankhwala, kugwiritsa ntchito zinthu zoyera kwambiri.	Kukana mankhwala bwino kwambiri, kukangana kochepa.	Kukana kukanda pang'ono.
Perfluoroalkoxy (PFA)	Kukana mankhwala kwambiri, kulimba kwambiri kuposa PTFE, ndi koyenera kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri.	Makampani opanga mankhwala, kugwiritsa ntchito madzi oyera kwambiri.	Kukana mankhwala kwapadera, kulimba kwambiri.	Zokwera mtengo kuposa zinthu zina monga PTFE.
Chomera chadothi	Kukana kwabwino kwambiri kwa kukanda, kukana kwabwino kwambiri kwa mankhwala ndi kutentha.	Kukumba, zoumba zadothi, kukonza mankhwala otentha kwambiri, mankhwala opangidwa ndi slurry m'mafakitale.	Kukana kwambiri kukanda, kukana mankhwala ndi kutentha.	Yofooka, ming'alu ikagundana kapena kutentha kwambiri.

Mapeto

Kusankha zipangizo zoyezera kuyenda kwa magetsi kumadalira zinthu zingapo, kuphatikizapo mphamvu ya mankhwala a madzi, kutentha ndi kupanikizika, komanso kupezeka kwa tinthu tolimba kapena zinthu zokwawa mu madzi. Zipangizo monga PTFE, Neoprene, ndi Polyurethane zimapereka kukana bwino kwa mankhwala ndi kukwawa, pomwe Ceramic ndi PFA zimapereka kulimba kwapamwamba komanso kukana kutentha kwambiri pa ntchito zovuta kwambiri.

Mwa kusankha mosamala zinthu zoyenera zogwirira ntchito, mafakitale amatha kuonetsetsa kuti akuyeza bwino kuchuluka kwa madzi, kuchepetsa ndalama zokonzera, komanso kutalikitsa nthawi yogwiritsira ntchito mita yoyendetsera madzi. Kaya ndi njira ya mankhwala, kugwiritsa ntchito matope, kapena kugwiritsa ntchito kutentha kwambiri, kusankha zinthu zoyenera zogwirira ntchito ndikofunikira kwambiri kuti zinthu zigwire bwino ntchito komanso kuti zitsimikizire kuti zinthuzo ndi zodalirika m'malo ovuta kwambiri.
