LJQF-7800-DN10-300 Critical Flow Venturi Sonic Nozzle Type Gas Flow Chithunzi Chowonetsedwa
  • LJQF-7800-DN10-300 Critical Flow Venturi Sonic Nozzle Type Gas Flow

Kufotokozera Kwachidule:

"Critical Flow Venturi Sonic Nozzle Gas Flow Standard Device" ndi mulingo wogwirizanitsa ndi kusamutsa mitengo yamayendedwe, ndipo ndi chipangizo choyezera chowerengera mtengo, kusamutsa mtengo komanso kuzindikira zida zowunikira mpweya. Izi zida amagwiritsa ntchito yovuta otaya Venturi nozzle monga muyezo tebulo ndi mpweya monga sing'anga mayeso kuti atsimikizire metrological, calibration ndi kuyendera osiyanasiyana mpweya otaya mamita .

The mtheradi kuthamanga transmitter ndi kutentha transmitter kukhazikitsidwa mu chipangizo ichi kuyeza mpweya kuthamanga ndi kutentha pamaso ndi pambuyo nozzle ndi flowmeter akuyesedwa, komanso nozzle kumbuyo kuthamanga. Dongosolo lowongolera limasonkhanitsa ndikusintha magawo osiyanasiyana munthawi yeniyeni panthawi yoyeserera. Makompyuta apansi amaweruza ndi kuwerengetsa deta yomwe imakwezedwa ndi makina otumizira mauthenga ndikusunga. Panthawi imeneyi, deta yosokonekera ndi transmitter yokha imachotsedwa. Atalandira deta pafupifupi kuchokera kompyuta m'munsi, kompyuta chapamwamba amazisunga mu Nawonso achichepere kutsimikizira zotsatira Nawonso achichepere, ndipo pa nthawi yomweyo amachita chiweruzo chachiwiri ndi kuwunika pa deta kusungidwa kuonetsetsa kuti deta nawo kuwerengetsera ndi zolondola ndi odalirika, ndi kukonzedwadi anazindikira.

Mu makina apakompyuta a chipangizocho, ntchito yokhazikitsa kapena kusintha deta yofunikira ya dongosolo imayikidwa. Kuphatikiza pa nkhokwe yotsimikizira zotsimikizira za ma transmitter, database yoyambira ya nozzle imamangidwanso kuti isunge magawo monga nambala ya serial ndi coefficient yotuluka ya nozzle iliyonse yokhala ndi chipangizocho. Ngati deta yotsimikizira za nozzle isintha kapena chopukusira chatsopano chasinthidwa, wogwiritsa ntchito amangofunika kusintha zofunikira.

  • Calibration medium: mpweya wabwino.
  • Njira yowerengera: njira yopondereza yoyipa.
  • Mayendedwe osiyanasiyana: (0.5～7800)m³/h (ndi mawonekedwe osungidwa kuti akulitse mpaka 16000m³/h).
  • Kukayikitsa kowonjezereka kwa chipangizo:U = 0.33%k = 2 pa). Perekani satifiketi yotsimikizira yoperekedwa ndi dipatimenti yotsimikizira za metroloji mdziko muno.
  • Mulingo wolondola wa nozzle wa Sonic: 0.2. Perekani satifiketi yotsimikizira yoperekedwa ndi dipatimenti yotsimikizira za metrology yapadziko lonse, ndipo zopangira ndi zitsulo zosapanga dzimbiri 304.
  • Kukhazikika kwa chipangizocho: ≤0.1%.
  • Chombo choyimirira: Mphamvu ya kuthamanga ndi kusinthasintha kwa kutentha pa data ya calibration imayendetsedwa mkati mwa 1/5 ya kusatsimikizika kwa muyeso wa chipangizo chonsecho.
  • Kuwongolera kwamalo otsimikizira: <3min. Kusintha kwanthawi ndikobwinoko kuposa 0.001s, kokhala ndi doko la kristalo ndipo kumatha kupatulidwa, kuyeza kwanthawi yayitali kumakulitsa kusatsimikizika.U = 3 × 10-6( k = 2) , ndipo satifiketi yoperekedwa ndi dipatimenti yotsimikizira za metrology yakuchigawo kapena yapamwamba imaperekedwa.
  • Kuyang'ana caliber: DN10, DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, okwana 15 calibers.
  • Paipi yoyendera: Pali mapaipi 7 oyendera okhala ndi ma diameter a DN50 (ogwirizana ndi DN40/32/25/15/10), DN80 (yogwirizana ndi 65), DN100, DN150 (yogwirizana ndi 125), DN200, DN250, ndi DN300. Kumtunda kwa payipi iliyonse yoyendera ndi chotchinga cha pneumatic, chomwe chimayendetsa kusamuka ndi kukanikiza kwa chitoliro chowongoka chamtunda. Kukula kwa khoma la payipi kumatengera muyezo wadziko lonse, wopangidwa ndi zitsulo zosapanga dzimbiri 304, zokhala ndi chopondera, komanso tebulo lowunikira lodzikweza.
