Izici zemitha yokugeleza kwe-Vortex

Ingalinganisa izinhlobo ezintathu zemidiya okuhlanganisa uketshezi, amagesi, kanye nomusi ogcwele/oshisayo kakhulu emhlabeni jikelele. Ifanelekela amanzi okupholisa ezimbonini, izinyibilikisi zamakhemikhali, igesi yemvelo, umoya ocindezelwe, kanye nomusi wezimboni, isusa isidingo samamitha ahlukene oketshezi oluhlukene futhi inciphise izindleko zokuthenga nokuphatha zamakhasimende.

Azikho izingxenye ezihambayo ngaphakathi kwemitha. Izingxenye eziyinhloko ziyimizimba ebushelelezi engaguquki kanye nezinzwa, ezigwema ngokuphelele izinkinga ezifana nokuguguleka kwe-impeller, ukungcola, kanye nokuvaleka kwamamitha okugeleza avamile. Akudingi ukuhlukaniswa nokuhlanza njalo ngaphansi kwezimo zokusebenza ezijwayelekile, kodwa kuphela ukuhlolwa ngezikhathi ezithile kwezintambo zezinzwa. Isikhathi sesevisi singadlula iminyaka eyi-10, okunciphisa kakhulu izindleko zokulungisa zesikhathi eside.

Ngokusekelwe kusimiso se-Karman Vortex Street, ukunemba kokulinganisa (±1.0%FS – ±1.5%FS) kuncike kakhulu emvamisa ye-vortex futhi akuthintwa ukuguquguquka kobuningi boketshezi, ingcindezi, noma izinga lokushisa ngaphakathi kobubanzi obuthile. Umklamo ovalwe wendlu yemitha kanye nenzwa umelana nokuphazamiseka kwe-electromagnetic, uthuli, kanye nomswakama ezindaweni zezimboni, okuqinisekisa ukuphindaphindwa okuhle kakhulu kokulinganisa.

Isilinganiso sokujika sifinyelela ku-1:10 kuya ku-1:20, okufanelekela izimo ezinokuguquguquka okukhulu kokugeleza (njengokuphakelwa kwe-reactor yamakhemikhali kanye nokulungiswa komthwalo webhoyila ngomusi). Ama-caliber ajwayelekile amboza i-DN15 - DN300, kanye namamodeli amakhulu e-caliber enziwe ngokwezifiso (kufika ku-DN600) ayatholakala ukuhlangabezana nezidingo zokulinganisa zamapayipi amancane kanye namapayipi amakhulu ezimboni.

Umzimba oluhlaza okwesibhakabhaka usebenzisa umklamo ohlelekile, okuholela ekumelaneni noketshezi okuphansi lapho kudlula. Ukulahlekelwa yingcindezi yawo kuphansi kakhulu kunokwamamitha okugeleza e-orifice kanye namamitha okugeleza e-turbine. Lesi sici sinciphisa ukusetshenziswa kwamandla kohlelo lokuthuthwa kwamapayipi, ikakhulukazi kumapayipi amakhulu ezimboni, futhi sehlisa kakhulu umthwalo wokusebenza kwemishini yamandla njengamaphampu amanzi namafeni, okuhlangabezana nezidingo zokonga amandla kanye nokuvikela imvelo.

Isekela izindlela eziningi zokufaka okuhlanganisa ukuxhumeka kwe-flange kanye ne-clamp-on. Inezidingo ezikhululekile zezingxenye zamapayipi aqondile aphezulu naphansi (ngokuvamile i-10D phezulu kanye ne-5D phansi), ezifanele izindawo zezimboni ezinesikhala esilinganiselwe. Izinto zemitha zingenziwa ngokwezifiso ngendlela eguquguqukayo: umzimba utholakala ngensimbi yekhabhoni, insimbi engagqwali engu-316L, i-Hastelloy, njll., futhi umzimba we-bluff ungenziwa nge-titanium alloy noma i-ceramic, engamelana nokushisa okuphezulu, ukucindezela okuphezulu, kanye nemidiya ebolile, ivumelane nobubanzi bokushisa obungu--40℃ - 400℃ kanye nokucindezela kokusebenza kwe-PN1.6 - PN4.0MPa.

Amamitha okugeleza kwe-vortex yesimanje ahlanganiswe kakhulu nama-converter ahlakaniphile, asekela isignali ye-analog engu-4 - 20mA kanye nokukhishwa kwesignali ye-pulse. Ahambisana nezinqubo zokuxhumana zezimboni ezijwayelekile njenge-MODBUS, i-HART, ne-Profibus, futhi angaxhuma kalula ezinhlelweni zokulawula ze-PLC ne-DCS, afeze ukuqapha kwesikhathi sangempela, ukudlulisa okukude, kanye nokuphathwa kwedatha yokugeleza okuphakathi ukuze kuhlangatshezwane nezidingo zokukhiqiza kwezimboni okuzenzakalelayo.
