I-LJQF-7800-DN10-300 I-Flow Venturi Sonic Nozzle Uhlobo lweGesi ejikelezayo

I-LJQF-7800-DN10-300 I-Flow Venturi Sonic Nozzle Uhlobo lwe-Gas Flow Umfanekiso obonisiweyo
  • I-LJQF-7800-DN10-300 I-Flow Venturi Sonic Nozzle Uhlobo lweGesi ejikelezayo

Inkcazo emfutshane:

I-"Critical Flow Venturi Sonic Nozzle Gas Flow Standard Device" ngumgangatho wokudibanisa nokudlulisa amaxabiso eyunithi yokuhamba, kwaye sisixhobo sokulinganisa esisemgangathweni sokulandelela ixabiso, ukudlulisa ixabiso kunye nokufumanisa izixhobo zokufumanisa ukuhamba kwegesi. Le seti yezixhobo isebenzisa i-critical flow Venturi nozzle njengetafile eqhelekileyo kunye nomoya njengendawo yokuvavanya ukwenza uqinisekiso lwe-metrological, ukulinganisa kunye nokuhlola iimitha ezahlukeneyo zokuhamba kwegesi.

Isidlulisi soxinzelelo olupheleleyo kunye nesidlulisi sobushushu esilungiselelwe kwesi sixhobo silinganisa uxinzelelo lokuhamba komoya kunye nobushushu ngaphambi nasemva kokuba umlomo kunye ne-flowmeter zivavanyiwe, kunye noxinzelelo lokubuyela umva kwemilomo. Inkqubo yolawulo iqokelela kwaye icwangcise iiparameter ezahlukeneyo ngexesha langempela ngexesha lenkqubo yokulinganisa. Ikhompyutha ephantsi igweba kwaye ilinganise idatha elayishwe ngumdlulisi kwaye iyigcine. Ngeli xesha, idatha egqwethiweyo ngumdlulisi ngokwayo iyasuswa. Emva kokufumana idatha ephakathi kwikhompyutha esezantsi, ikhompyutha ephezulu iyigcina kwisiseko sedatha sokuqinisekisa iziphumo zomdlulisi, kwaye kwangaxeshanye yenza isigqibo sesibini kunye nokuhlola idatha egciniweyo ukuqinisekisa ukuba idatha ebandakanyekayo ekubalweni ichanekile kwaye ithembekile, kwaye ukulungiswa kuyafezekiswa ngokwenene.

Kwinkqubo yekhompyutha yesixhobo, ukusebenza kokuseka okanye ukuguqula idatha esisiseko yenkqubo kuyamiselwa. Ukongeza kwisiseko sedatha yeziphumo zokuqinisekisa i-transmitter, isiseko sedatha ye-nozzle sikwakhiwe ukugcina iiparameter ezifana nenombolo ye-serial kunye ne-outflow coefficient ye-nozzle nganye exhotyiswe ngesixhobo. Ukuba idatha yokuqinisekisa i-nozzle iyatshintsha okanye i-nozzle entsha itshintshiwe, umsebenzisi kufuneka atshintshe idatha esisiseko kuphela.
