LJQF-7800-DN10-300 Ukuqukuqela Okubalulekileyo Venturi Sonic Nozzle Uhlobo lwerhasi Flow Umfanekiso obonakalayo
  • LJQF-7800-DN10-300 UkuHamba okuBalulekileyo Venturi Sonic Nozzle Uhlobo lokuHamba kwerhasi

Inkcazelo emfutshane:

I-"Critical Flow Venturi Sonic Nozzle Gas Flow Standard Device" ngumgangatho wokudibanisa kunye nokudluliselwa kwexabiso leyunithi yokuhamba, kwaye sisixhobo sokulinganisa okusemgangathweni ukulandelwa kwexabiso, ukuhanjiswa kwexabiso kunye nokufumanisa izixhobo zokubona ukuhamba kwegesi. Olu luhlu lwezixhobo lisebenzisa umbhobho obalulekileyo ohambayo weVenturi njengetafile esemgangathweni kunye nomoya njengendawo yokuvavanya ukwenza ungqinisiso lwemitha, ulungelelwaniso kunye nokuhlola iimitha zokuhamba kwegesi ezahlukeneyo.

Isidluliseli soxinzelelo olupheleleyo kunye nesidlulisi sobushushu esilungiselelwe kwesi sixhobo silinganisa uxinzelelo lokuhamba komoya kunye nobushushu phambi nasemva komlomo kunye ne-flowmeter evavanywayo, kunye noxinzelelo lomva wombhobho. Inkqubo yokulawula iqokelela kwaye iqhube iiparamitha ezahlukeneyo ngexesha langempela ngexesha lenkqubo yokulinganisa. Ikhompyuter esezantsi igweba kwaye ilinganise idatha efakwe yi-transmitter kwaye iyigcine. Ngeli xesha, idatha egqwethiweyo yi-transmitter ngokwayo iyacinywa. Emva kokufumana idatha ye-avareji evela kwikhompyuter esezantsi, ikhompyuter ephezulu igcina kwisiseko sedatha yesiphumo sokuqinisekisa, kwaye kwangaxeshanye yenza isigwebo sesibini kunye nokuhlolwa kwedatha egciniweyo ukuqinisekisa ukuba idatha ebandakanyekayo ekubaleni ichanekile kwaye inokuthenjwa, kwaye ukulungiswa kuyenzeka ngokwenene.

Kwinkqubo yekhompyuter yesixhobo, ukusebenza kokuseka okanye ukuguqula idatha esisiseko yenkqubo iseti. Ukongeza kwidathabheyisi yeziphumo zoqinisekiso lomthumeli, isiseko sesiseko sombhobho sikwakhiwe ukugcina iiparameters ezifana nenombolo yesiriyali kunye ne-outflow coefficient yomlomo ngamnye oxhotyiswe ngesixhobo. Ukuba idatha yokuqinisekisa i-nozzle iyatshintsha okanye i-nozzle entsha itshintshwe, umsebenzisi ufuna kuphela ukuguqula idatha esisiseko.
