I-LCD sensor turbine flow met yamanzi

Umgomo Wokusebenza

I-turbine flowmeter ine-turbine, lapho isetshenziswa, kufanele ifakwe epayipi elinamandla, futhi zombili iziphetho zisekelwa ama-bearings. Lapho uketshezi ludlula nge-turbine, uketshezi luthinta i-turbine blade futhi liqhube ukujikeleza kwe-turbine blade. Ithuluzi lokulinganisa le-turbine flowmeter lilinganisa ukugeleza ngokugeleza kwesivinini se-angular ye-turbine blade. Indlela esetshenzisiwe ukuthi i-angular velocity ye-blade ilingana ne-velocity fluid.

I-velocity ye-angular itholwa ngokuzwa ikhoyili efakwe kwikhabethe. I-Flux kazibuthe yokuzwa i-coil izoshintshwa lapho i-turbine blade isika insimbi engapheli kazibuthe ngaphakathi kwezindlu futhi ikhiqize imigqa yasensimini kazibuthe. I-Coil ezwayo ithumela umjikelezo we-magnetic flux umjikelezo wokuguqula isiginali ku-amplifier yamathuluzi wokulinganisa ukukhulisa isiginali.

Isiginali ye-Pulse ikhiqizwa ngokulingana okuqondile kwesilinganiso sokugeleza, futhi isiginali yokushayela ithunyelwa kwisifunda sokuguqula, futhi isiginali yokushayela iguqulwa ibe yinani lokugeleza elisheshayo nelikhonjisiwe.
