Isithombe Esivelele Sokugeleza Kwegesi se-LJQF-7800-DN10-300 Critical Flow Venturi Sonic Nozzle Type
  • I-LJQF-7800-DN10-300 Ukugeleza Okubalulekile kwe-Venturi Sonic Nozzle Uhlobo Lokugeleza Kwegesi

Incazelo emfushane:

I-“Critical Flow Venturi Sonic Nozzle Gas Flow Standard Device” iyindinganiso yokuhlanganisa nokudlulisa amanani eyunithi yokugeleza, futhi iyindinganiso ejwayelekile yokulinganisa ukulandeleka kwenani, ukudluliselwa kwenani kanye nokutholwa kwemishini yokuthola ukugeleza kwegesi. Leli sethi lamadivayisi lisebenzisa i-critical flow Venturi nozzle njengethebula elijwayelekile kanye nomoya njengendawo yokuhlola ukwenza ukuqinisekiswa kwe-metrological, ukulinganiswa kanye nokuhlolwa kwamamitha okugeleza kwegesi ahlukahlukene.

Isithumeli sokucindezela okuphelele kanye nesithumeli sokushisa esilungiselelwe kule divayisi silinganisa ingcindezi yokuhamba komoya kanye nezinga lokushisa ngaphambi nangemva kokuhlolwa kwe-nozzle kanye ne-flowmeter, kanye nengcindezi yangemuva kwe-nozzle. Uhlelo lokulawula luqoqa futhi lucubungule amapharamitha ahlukahlukene ngesikhathi sangempela ngesikhathi senqubo yokulinganisa. Ikhompyutha ephansi iyahlulela futhi ilinganisele idatha elayishwe yi-transmitter bese iyigcina. Phakathi nalesi sikhathi, idatha ehlanekezelwe yi-transmitter uqobo iyasuswa. Ngemva kokuthola idatha emaphakathi kusuka kukhompyutha ephansi, ikhompyutha ephezulu iyigcina kusizindalwazi semiphumela yokuqinisekisa i-transmitter, futhi ngesikhathi esifanayo yenza isahlulelo sesibili kanye nokuhlola idatha egciniwe ukuqinisekisa ukuthi idatha ehilelekile ekubalweni inembile futhi ithembekile, futhi ukulungiswa kuyenzeka ngempela.

Kuhlelo lwekhompyutha lwedivayisi, ukusebenza kokusungula noma ukuguqula idatha eyisisekelo yesistimu kuyasethwa. Ngaphezu kwesizindalwazi semiphumela yokuqinisekisa i-transmitter, isizindalwazi esiyisisekelo se-nozzle sakhiwe futhi ukugcina amapharamitha afana nenombolo ye-serial kanye ne-outflow coefficient ye-nozzle ngayinye efakwe kudivayisi. Uma idatha yokuqinisekisa i-nozzle ishintsha noma i-nozzle entsha ishintshwa, umsebenzisi udinga kuphela ukuguqula idatha eyisisekelo.
