1. Inkcazo
Imitha yokuhamba kwe-vortex sisixhobo sokulinganisa ukuhamba kohlobo lwe-frequency esisekelwe kumgaqo weKarman Vortex Street. Silinganisa izinga lokuhamba kolwelo ngokufumanisa imvamisa yee-vortices eziveliswa xa ulwelo ludlula emzimbeni we-bluff (i-vortex generator) kwipayipi. Sisixhobo esingadibaniyo, esingenasondlo esisetyenziswa kakhulu kulawulo lwenkqubo yemizi-mveliso, esifanelekileyo ukulinganisa iigesi, ulwelo, kunye nomphunga.
2. Umgaqo Wokusebenza
Xa ulwelo oluzinzileyo luhamba emzimbeni we-bluff ofakwe emzimbeni wemitha, ii-vortices ezitshintshanayo zenziwa kumacala omabini omzimba we-bluff—le nto ibizwa ngokuba yiKarman Vortex Street. Ubuninzi bokuchitheka kwe-vortex buhambelana ngokuthe ngqo nesantya solwelo (kwaye abunamsebenzi nobuninzi bolwelo, uxinzelelo, kunye nobushushu ngaphakathi koluhlu oluthile). I-sensor eyakhelwe ngaphakathi (i-piezoelectric okanye i-capacitive) ibona utshintsho loxinzelelo olubangelwa kukuchitheka kwe-vortex, iziguqule zibe ziimpawu zombane, kwaye i-converter ibala isantya sokuhamba ngokukhawuleza kunye nesantya sokuhamba esiqokelelweyo ngokusekelwe kwisantya se-vortex.
3. Iimpawu eziphambili
- Ukuguquguquka kolwelo olubanzi: Ifanelekile ukulinganisa ulwelo, iigesi, kunye nomphunga ogcweleyo/oshushu kakhulu, isusa imfuneko yeemitha ezahlukeneyo zemidiya eyahlukeneyo, inciphisa iindleko zokuthenga zabathengi.
- Uzinzo Oluphezulu Lokulinganisa kunye Nokuphazamiseka Okuphantsi: Umgaqo wokulinganisa ulula kwaye uthembekile, awunazo iindawo ezishukumayo ngaphakathi komzimba wemitha, uphepha ukuguguleka, ukungcola, kunye nokuvaleka. Unamandla amakhulu okulwa nokuphazamiseka ngokuchasene nobushushu bangaphandle kunye nokuguquguquka koxinzelelo.
- Uluhlu Olubanzi Lokuhamba Kombane kunye Nokugubungela IiCalibre: Umlinganiselo wokujika ungafikelela kwi-1:10 ukuya kwi-1:20, ulungelelanise nokuguquguquka okukhulu kokuhamba kombane. IiCalibre eziqhelekileyo ziqala kwi-DN15 ukuya kwi-DN300, kunye neemodeli ezinkulu ezenziwe ngokwezifiso (ukuya kuthi ga kwi-DN600) ezifumanekayo kwiimeko zokuhamba kombane okukhulu kwemizi-mveliso.
- Ukulahleka Koxinzelelo Oluphantsi kunye Nokonga Amandla: Uyilo lomzimba we-bluff olucwangcisiweyo lunciphisa ukumelana nolwelo, nto leyo ebangela ukulahleka koxinzelelo oluphantsi xa kuthelekiswa neemitha zokuhamba kwe-turbine okanye i-orifice, nto leyo enceda abathengi banciphise ukusetyenziswa kwamandla emibhobho.
- Ulwakhiwo Olulula kunye nobomi benkonzo ende: Izinto zangaphakathi ezimbalwa, amandla aphezulu oomatshini, kunye nezinto ezingagugiyo (ezifana nentsimbi engagqwaliyo engama-316L, iHastelloy) yomzimba oluhlaza kunye nomzimba wemitha. Ubomi benkonzo yezinto ezibalulekileyo budlula iminyaka eli-10 phantsi kweemeko zokusebenza eziqhelekileyo.
4. Iimpawu ezifanelekileyo zolwelo kunye nokusetyenziswa
- Ulwelo: Amanzi acocekileyo, izinyibilikisi zeekhemikhali, iimveliso zepetroleum, amanzi okupholisa, kunye nezinye izinto ezithambileyo nezingonakalisiyo/ezingonakalisiyo kangako.
- Iigesi: Igesi yendalo, umoya oxinzelelweyo, initrogen, ioksijini, igesi yombhobho, kunye nezinye iigesi ezomileyo nezicocekileyo.
- Umphunga: Umphunga ogcweleyo kunye nomphunga oshushu kakhulu osetyenziswa kakhulu kwimveliso yemizi-mveliso.
- Iinkalo eziphambili zokusetyenziswa: I-Petroleum kunye ne-petrochemical, ishishini leekhemikhali, ukuveliswa kwamandla, i-metallurgy, ukufudumeza kunye nokungenisa umoya, unyango lwamanzi, kunye nokutya neziselo. Ithandwa kakhulu kwiiprojekthi zokulinganisa umphunga webhoyila kunye nolawulo lokuhamba kwepayipi yemizi-mveliso.
5. Ulwazi oluPhambili loRhwebo lwaMazwe angaphandle (Izatifikethi kunye neenketho zezinto eziphathekayo)
- Iziqinisekiso zaMazwe ngaMazwe: Ziyahambelana nemigangatho yamazwe ngamazwe efana ne-ISO 9001, CE, ATEX (isiqinisekiso sokumelana nokuqhuma kweendawo ezinobungozi), UL (imarike yaseMntla Melika), kunye ne-PED (i-EU Pressure Equipment Directive), ukuqinisekisa ukufikelela ngokulula kwiimarike zehlabathi.
- Ukwenziwa ngokwezifiso kwezinto: Umzimba wemitha ufumaneka ngentsimbi yekhabhoni, intsimbi engagqwaliyo engama-316L, kunye neHastelloy; umzimba webluff ungenziwa ngokwezifiso nge-titanium alloy okanye izinto zeseramikhi ukuze zilungelelaniswe ne-corrosive okanye i-media yobushushu obuphezulu kumazwe ahlukeneyo nakwiindawo ezahlukeneyo.
- Imveliso kunye noNxibelelwano: Ixhasa iziphumo zesignali ezisemgangathweni (4-20mA, i-pulse) kunye neenkqubo zonxibelelwano (MODBUS, HART, Profibus), ezihambelana neenkqubo zolawulo lwemizi-mveliso eziphambili eYurophu, eMelika, nakuMzantsi-mpuma weAsia.
