28khz Ultrasonic Transducer

Ultrasonic welding transducer ka mea nui o ka ʻōnaehana kani ultrasonic holoʻokoʻa, a ua hoʻohana ʻia ka transducer no ka hoʻololi ʻana i ke alapine kiʻekiʻe a me ka uila kiʻekiʻe i ka ikehu kinetic mechanical.A loaʻa iā ia kekahi mau disc ceramic piezoelectric i hoʻopaʻa ʻia ma lalo o ke kaomi ma waena o nā poloka metala ʻelua.Aia ma waena o kēlā me kēia diski kahi pā metala lahilahi, kahi e hana ai i ka electrode.Ke hāʻawi ʻia kahi hōʻailona uila sinusoidal i ka transducer ma o nā electrodes, hoʻonui a hoʻopaʻa ʻia nā discs, hana i nā axial vibrations ʻO ka ʻōnaehana ultrasonic he ʻekolu mau ʻāpana, ultrasonic generator, ultrasonic transducer a me ultrasonic hoen, a ʻo nā ʻāpana ʻekolu he ʻōnaehana ultrasound piha.

Eia nā hiʻohiʻona o ka ultrasonic transducer:
Haʻahaʻa resonant impedance, kiʻekiʻe mechanical quality kumu.
Kiʻekiʻe electro-acoustic hoʻololi pono a me ka nui amplitude.
ʻO ka wela haʻahaʻa, ka laulā wela nui;ʻO ka drift hana liʻiliʻi, hana paʻa.
Mea maikaʻi, ola lōʻihi.

'Ōlelo no ka hoʻohana:
Pono e kūlike nā alapine o ka ultrasonic transducer, booster a me horn me kekahi i kekahi.
Pono e emi nā alapine o ka pū kani a me ka booster ma mua o ke alapine o ka transducer.
Pono ka ʻili pili e hōʻoia i ke kūpaʻa a me ka palahalaha, a pono ke kūpono o ka torque pili.
Pono e hilinaʻi ʻia ka welding o ka pā electrode a uhi ʻia me ke kāpili damping.
Pono e emi ka mahana hana o ka ultrasonic transducer ma mua o 60 °C, a e emi iho ka mana hoʻokomo ma mua o ka mana helu.
