Ultrasonic transducer ke sesebelisoa sa ho fetola matla se fetolang matshwao a motlakase a fapanyetsanang hore e be matshwao a acoustic kapa matshwao a acoustic hore e be matshwao a motlakase ka hara sebaka sa maqhubu a ultrasonic. Ke sesebelisoa se ka sehloohong sa lisebelisoa tsa ultrasonic, kahoo ho sa tsotellehe hore na ke mochine oa transduction kapa ts'ebetso Moqapi le lihlopha tse ling li fumane tlhokomelo ea nako e telele.
Mekhahlelo ea ts'ebetso ea li-transducers tsa ultrasonic
Ultrasonic transducer ke sesebelisoa sa ho fetola matla, 'me tlhaloso ea eona ea ts'ebetso le tlhahlobo e hloka litekanyo tse ngata. Likarolo tse ikhethang tsa transducer ea ultrasonic li kenyelletsa maqhubu a resonance, frequency bandwidth, electromechanical coupling coefficient, electroacoustic performance, mechanical quality factor, impedance characters, frequency Characteristics, directivity, transmitting and receive sensitivity, joalo-joalo. Bakeng sa ho amohela li-transducers tsa ultrasonic, sehlopha se pharaletseng sa maqhubu le kutlo e phahameng le tharollo lia hlokahala. Ka hona, ts'ebetsong e khethehileng ea moralo oa transducer, litekanyo tse amehang tsa transducer li tlameha ho etsoa ho latela kopo e khethehileng Moralo o utloahalang.
Tlhahlobo ea mokhoa oa ultrasonic transducer
Li-transducer tsa Ultrasonic li kenyelletsa sistimi ea potoloho, sistimi ea vibration ea mochini le sistimi ea acoustic, 'me tse tharo li kopantsoe ka mokhoa o kopaneng ho ba bonngoe bo kopaneng ha transducer e sebetsa. Sena se etsa qeto ea mokhoa oa ho etsa lipatlisiso bakeng sa eona ke ho kopanngoa ha lisebelisoa tsa elektronike Mekhoa ea ho etsa lipatlisiso ea saense, mechanics, acoustics, joalo-joalo, le ka papiso ea electro-mechanical-acoustic, e nolofalletsa ba bararo ho sebelisa setšoantšo se tšoanang sa electromechanical le li-equations tse lekanang ho etsa lipatlisiso tse tebileng habonolo.
Jenereithara ea ultrasonic e fetola matla a maholo a 220V hore e be high-frequency current, 'me transducer ea ultrasonic e fetola maqhubu a phahameng-frequency hona joale hore e be mochine o sisinyehang, ebe o holisa (ho fokotsa) amplitude ka lenaka la ultrasonic, ebe qetellong o o fetisetsa ho hlooho ea sesebelisoa bakeng sa mosebetsi. Li-transducer tsa Ultrasonic ka kakaretso li na le mefuta e 'meli: magnetostrictive le piezoelectric ceramics.

Mofuta ona oa sandwich transducer o hlahisa maqhubu a tsitsitseng a ultrasonic ha mojaro o fetoha, e leng mokhoa oa mantlha le o ka sehloohong oa ho fumana mohloli oa motlakase oa motlakase oa motlakase. Ho ea ka meralo e fapaneng, mefuta ea li-transducers tsa ultrasonic ke haholo:
Mofuta oa kholomo (mofuta oa NTK)
Mofuta oa terompeta e sothehileng (mofuta oa Benengxin)
Sekoahelo se ka morao sa tšepe
Mofuta oa sekotwana sa aluminium
Li-transducers tsa Ultrasonic li loketse haholo bakeng sa welding ea ultrasonic, ultrasonic cutting, ultrasonic liquid treatment, ultrasonic atomization spraying le ultrasonic metal melt treatment.
