Izidingo Zesilinganiso Esimaphakathi Uma Kukalwa Nge-Precession Vortex Flow Meter

2020-08-12
Uma usebenzisa imitha yokugeleza ye-vortex eyandulele ukukala ngokunembile ukugeleza okuphelele, lezi zinkinga ezilandelayo kufanele zicatshangelwe:
1. Ukumelana nokugeleza kwepayipi kufanele kube ngu-2×104~7×106. Uma idlula lobu bubanzi, inkomba ye-flowmeter, okungukuthi, inombolo ye-Stroha ayiyona ipharamitha, futhi ukunemba kunciphisa.
2. Izinga lokugeleza kwe-medium kufanele libe phakathi kwebanga elidingekayo, ngoba imitha yokugeleza ye-vortex yangaphambili ikala ukugeleza okuphelele ngokusekelwe kubuningi. Ngakho-ke, izinga lokugeleza le-medium kufanele libe nomkhawulo, futhi ama-mediums ahlukene abe namazinga okugeleza ahlukene.
(1) Uma okuphakathi kuwumhwamuko, isivinini esikhulu kufanele sibe ngaphansi kuka-60 m/s
(2) Uma okuphakathi kuyisitimu, kufanele kube ngaphansi kuka-70 m/s
(3) Izinga lokugeleza lomkhawulo ophansi libalwa kusukela kumdwebo wejika elihlobene noma ukubala kwefomula yephaneli yensimbi ngokusekelwe ku-viscosity nokuminyana okuhlobene.
(4) Ngaphezu kwalokho, ingcindezi yokusebenza kanye nezinga lokushisa eliphakathi nendawo kufanele kube phakathi kwebanga elidingekayo.

Izici ze-precession vortex flow meter.
1. Izinzuzo ezibalulekile
(1) Inkomba yokulinganisa yemitha ngeke ilinyazwe ukucindezela okusebenzayo koketshezi, izinga lokushisa, ukuminyana okulinganiselwe, i-viscosity nokushintsha kokwakheka, futhi asikho isidingo sokuphinda ukulinganisa lapho kuqaqa futhi kufakwa izingxenye zokuhlola;
(2) Isilinganiso sobubanzi bokulinganisa sikhulu, uketshezi lufinyelela ku-1:15, futhi umhwamuko ufinyelela ku-1:30;
(3) Ukucaciswa kwepayipi cishe akunamkhawulo, 25-2700 Mm;
(4) Ukulimala kwengcindezi yomsebenzi kuncane kakhulu;
(5) Khipha ngokushesha isignali ye-elekthronikhi ngokuhambisana nokugeleza okuphelele, ngokunemba okuphezulu, okufika ku-±1%;
(6) Ukufakwa kulula, inani lesondlo lincane, futhi amaphutha avamile ambalwa kakhulu.
2. Amaphutha amakhulu
(1) Izinga lokugeleza eliguquguqukayo nokugeleza kwesiphuzo esiphuphumayo kuzofaka engozini ukunemba kokulinganisa. Kunemithethonqubo yesigaba sokuxhuma endaweni engaphezulu, ephakathi naphansi yephaneli yensimbi (ezintathu d phezulu naphansi komfula, i-1D phakathi nendawo naphansi komfula). Uma kunesidingo, isilungisisi kufanele siguqulwe emaceleni akhuphuka nomfula;
(2) Uma izingxenye zokuhlola zingcolile, ukunemba kokulinganisa kuzophazamiseka. Izingxenye zokugeleza okuphelele kanye nezimbobo zokuhlola kufanele zihlanzwe ngophethiloli wemoto, uphethiloli, i-ethanol, njll.
3. Ukufakwa kwe-precession vortex flowmeter
1. Uma i-flowmeter ifakiwe, inqatshelwe ukwenza i-arc welding ngokushesha ku-flange yokuhweba kwayo yokungenisa nokuthumela ngaphandle ukuvimbela ukushisa izingxenye zangaphakathi ze-flowmeter.
2. Zama ukuhlanza ipayipi elisanda kufakwa noma elilungiswe, bese ufaka i-flowmeter ngemva kokukhipha ukungcola epayipini.
3. I-flowmeter kufanele ifakwe endaweni evumela ukulungiswa, ngaphandle kwethonya lezindawo ezinamandla kazibuthe, futhi ngaphandle kokudlidliza okudambisayo okusobala kanye nezingozi zokushisa ezikhazimulayo;
4. I-flowmeter ayifanele izindawo lapho ukugeleza okuphelele kuvame ukuphazanyiswa futhi kukhona ukugeleza kwesiphuzo esiphunduzayo noma iziphuzo ezicindezelayo zokusebenza;
5. Uma i-flowmeter ifakwe ngaphandle, kufanele kube nesembozo ekugcineni okuphezulu ukuvimbela ukungena kwemvula kanye nokuchayeka elangeni kungalimazi impilo ye-flowmeter;
6. I-flowmeter ingafakwa kunoma iyiphi i-angle yokubuka, futhi ukungena koketshezi kufanele kuhambisane nokungena okumakwe ku-flowmeter;
7. Esizeni sokwakhiwa kwepayipi, kufanele kucatshangelwe ukufaka imikhiqizo noma izifutho zensimbi ukuvimbela ukudonsa okubi noma ukugqabuka kwe-flowmeter;
8. I-flowmeter kufanele ifakwe i-coaxially ngokuphuma kwepayipi, futhi ivimbele ucezu lokuvala kanye nebhotela elingafakwanga odongeni lwangaphakathi lwepayipi;
9. Uma usebenzisa ukunikezwa kwamandla okushintsha kwangaphandle, i-flowmeter kufanele ibe nedivaysi ethembekile yokusekela phansi. Intambo yaphansi ayikwazi ukusetshenziswa nesofthiwe yesistimu yamanje ebuthakathaka. Ngesikhathi sokufakwa noma ukulungiswa kwepayipi, intambo yaphansi yesofthiwe ye-arc welding ayikwazi ukweqa nebha yensimbi ye-flowmeter. .
