I-flowmeter ye-electromagnetic ekufakweni nasekusetshenzisweni kwenqubo kuzoba nezinkinga ezithile, okuholela ezinkingeni zokulinganisa, iningi lesizathu ukuthi i-flowmeter ezinkingeni zokufakwa kanye nokuqaliswa kokusebenza, lezi yizici ezibalulekile zokwehluleka.
1. Ohlangothini oluphezulu lwemitha yokugeleza, uma kukhona ama-valve, izindololwane, amaphampu anezindlela ezintathu kanye nezinye iziphazamisi, ingxenye yepayipi eqondile engaphambili kufanele ibe ngaphezu kuka-20DN
2, ukufakwa kwe-flowmeter kagesi, ikakhulukazi isikhathi sokugeleza kwezinto ze-polytetrafluoroethylene lining, amabhawodi axhumanisa ama-flange amabili kufanele anake ukuqina okufanayo, ngaphandle kwalokho kulula ukuchoboza i-polytetrafluoroethylene lining, nge-torque wrench.
3, lapho ukuphazamiseka kwamanje kwepayipi kuphambuka, igagasi le-electromagnetic lesikhala noma ukuphazamiseka kwensimu yamagnetic enkulu yenjini. Ukuphazamiseka kwamanje okuphambukayo emapayipini kuvame ukulinganiswa ngokwanelisayo ngokuvikelwa okuhle komhlaba ngamunye. Kodwa-ke, uma ipayipi linomsinga ophambukayo onamandla akunakunqotshwa, kuyadingeka ukuthatha izinyathelo zokuvikela inzwa yokugeleza kanye nephayiphi. Ukuphazamiseka kwamagagasi e-electromagnetic esikhala ngokuvamile kungeniswa ngekhebula lesiginali, elivame ukuvikelwa ukuvikela ungqimba olulodwa.
4, ngokuvamile amamitha okugeleza kagesi nawo anezidingo zezinga lokuvikela, ngokuvamile izinga lokuvikela elihlanganisiwe yi-IP65, uhlobo oluhlukanisiwe yi-IP68, uma ikhasimende linezidingo zendawo yokufaka amathuluzi, indawo yokufaka eMithonjeni engaphansi komhlaba noma kwezinye izindawo ezimanzi, kunconywa ukuthi amakhasimende akhethe uhlobo oluhlukanisiwe.
5, ukuze kugwenywe ukuphazamisa isignali, isignali phakathi komthumeli kanye nesiguquli kumele sidluliselwe ngocingo oluvikelwe, ikhebula lesignali kanye nomugqa wamandla akuvunyelwe ukufakwa ngokuhambisana epayipini lensimbi lekhebula elifanayo, ubude bekhebula lesignali ngokuvamile akumele budlule ku-30m.
6, ukuze kuqinisekiswe ukuthi ishubhu lokulinganisa i-electromagnetic flow transmitter ligcwele i-medium elinganisiwe, kunconywa ukuthi kufakwe ngokuqondile, ukugeleza kusuka phansi kuya phansi, ikakhulukazi ukugeleza kwezigaba ezimbili okuqinile koketshezi, kumele kufakwe ngokuqondile. Uma ukufakwa okuvundlile kuphela kuvunyelwe endaweni, qiniseka ukuthi ama-electrode amabili asendaweni efanayo evundlile.
7, uma uketshezi olulinganisiwe luthwala izinhlayiya, njengodaka lokulinganisa, indle, njll., i-flowmeter kagesi kumele ifakwe ngokuqondile, futhi igcine ukugeleza kusuka phansi kuya phansi, ukuqinisekisa ukuthi i-flowmeter kagesi ihlala igcwele ishubhu, kodwa futhi inganciphisa ngempumelelo ukubukeka kwamabhamuza.
8. Izinga lokugeleza kwe-flowmeter ye-electromagnetic lingaphakathi kwebanga elingu-0.3 ~ 12m/s, futhi ububanzi be-flowmeter bufana nobepayipi lenqubo. Uma izinga lokugeleza epayipini liphansi, alikwazi ukuhlangabezana nezidingo ze-flowmeter yebanga lokugeleza, noma ukunemba kokulinganisa kungephezulu kuleli zinga lokugeleza, zama ukwandisa izinga lokugeleza endaweni engxenyeni yethuluzi, bese usebenzisa uhlobo lwethubhu lokuncibilikisa.
9, i-flowmeter kagesi ingafakwa epayipini eliqondile, ingafakwa nasepayipini elivundlile noma elithambekele, kodwa idinga ukuthi umugqa ophakathi wama-electrode amabili ube sesimweni esivundlile.
10, i-flowmeter kagesi ekusetshenzisweni okulandelayo kwenqubo yokuhlanza njalo ithuluzi, hlola njalo inkinga ye-flowmeter:
(1) Ukuguguleka kwe-electrode ye-electromagnetic flowmeter sensor, ukugqwala, ukuvuza, ukukala. Ikakhulukazi kuma-electrode avuvukalayo, angcoliswe kalula, aqukethe isigaba esiqinile soketshezi olungahlanzekile;
(2) ukwehla kokufakwa kwe-acciation coil insulation;
(3) Ukushisa kwe-converter kuyancipha;
(4) Ukwehluleka kwesekethe yokuguqula;
(5) Ikhebula lokuxhuma lonakele, lifinyeziwe, futhi limanzi;
(6) Izinguquko ezintsha ezimweni zokusebenza kwethuluzi azikhishwa ngaphandle.
