Izinzuzo zeVortex Flowmeters

Ama-Vortex flowmeters ayizinto zokulinganisa ukugeleza kohlobo lwejubane ezisebenza ngesimiso se-Karman Vortex Street Effect. Asetshenziswa kabanzi ekulawuleni inqubo yezimboni ukulinganisa ukugeleza kwamagesi, uketshezi, kanye nomusi, ngezinzuzo ezilandelayo eziyinhloko:

1. Ukunemba Okuphezulu Kokulinganisa Nokuzinza Okuqinile

Ukunemba kokulinganisa akuthinteki kakhulu yizinguquko kumapharamitha aphakathi njengokucindezela, izinga lokushisa, kanye nobuningi. Ukunemba kungafinyelela ku-±0.5%R koketshezi, kanye no-±1%R wamagesi kanye nomusi, ngephutha lokuphindaphinda elingaphansi kuka-±0.2%. Ifakwe izingxenye zokuthola i-piezoelectric noma i-capacitive, inamandla amakhulu okulwa nokuphazamiseka kwezibonakaliso, iqinisekisa idatha ezinzile ngesikhathi sokusebenza kwesikhathi eside ngaphandle kokulinganiswa okuvamile.

2. Uhlu Olubanzi Lwemidiya Esebenzayo

Ingalinganisa ngesikhathi esisodwa ukugeleza koketshezi, amagesi, kanye nomusi, njengamanzi, izixazululo ze-acid-base, umoya, igesi yemvelo, umusi ogcwele, kanye nomusi oshisayo kakhulu. Njengoba ingenazo izingxenye zemishini ezihambayo, ngeke ivalwe noma igugiswe inani elincane lokungcola (njengezinhlayiya kanye nemicu) endaweni yokusebenza, okwenza ifanelekele izimo zokusebenza eziyinkimbinkimbi.

3. Isakhiwo Esilula Nezindleko Zokulungisa Eziphansi

Inzwa isebenzisa umklamo ohlanganisiwe futhi isekela izindlela zokufaka eziguquguqukayo (ukuxhumeka kwe-flange, uxhumano olunezintambo, njll.), okususa isidingo sokuguqulwa okwengeziwe kwesigaba sepayipi eliqondile (amanye amamodeli ahambisana nezingxenye zepayipi eziqondile ezimfushane). Ngaphandle kwezingxenye ezisengozini njenge-rotors nama-impeller, ukulungiswa kwansuku zonke kudinga ukuhlolwa okuvamile kokusebenza kokuvala phakathi kwenzwa nepayipi, okuholela ezindleleni zokusebenza nezokulungisa eziphansi kakhulu uma kuqhathaniswa namamitha okufuduka amahle njengemitha yokuhamba kwe-turbine kanye nemitha yokuhamba kwegiya eliyindilinga.

4. Isilinganiso Sokuguquguquka Okubanzi Kwezimo Zokuguquguquka Kokugeleza

Isilinganiso sokujika singafinyelela ku-1:10 ~ 1:30, okuvumela ukulinganisa okunembile kwamazinga okugeleza aphakathi nendawo kusukela phansi kuya phezulu. Ilungele izinqubo zezimboni ezinezinguquko eziningi zokugeleza, njengokudla kwe-reactor yamakhemikhali, ukusatshalaliswa komusi wesitshalo samandla, kanye nokudluliswa kwegesi kamasipala.

5. Ukukhishwa Kwedijithali Kokuhlanganiswa Kwesistimu Okulula

Isekela imiphumela ejwayelekile yesignali kufaka phakathi amasignali e-analog angu-4-20mA, amasignali e-pulse, kanye namasignali edijithali e-RS485 (Modbus-RTU). Ingaxhunywa ngqo kuma-PLC, izinhlelo zokulawula ze-DCS noma amapulatifomu e-inthanethi yezinto zezimboni ukuze kufezwe ukuqapha ukugeleza okukude, ukulinganisa okuqongelelekayo kanye nokulawula okuzenzakalelayo, kuhlangatshezwane nezidingo zokuthuthukiswa kwedijithali yezimboni.

6. Izinga Lokushisa Eliphezulu Nokumelana Nokucindezela Okuphezulu Kwezimo Zokusebenza Ezinzima

Inzwa ingenziwa ngezinto ezingagqwali nezimelana nokushisa okuphezulu njengensimbi engagqwali kanye neHastelloy, ezivumelanisa nezimo zokusebenza lapho izinga lokushisa eliphakathi lisukela ku--200℃ kuya ku-+550℃ futhi ingcindezi ifinyelela amashumi ama-megapascal. Isetshenziswa kabanzi ezimbonini ezishisa kakhulu nezicindezelayo eziphezulu njenge-petrochemical, i-metallurgy kanye namandla kagesi.
