ʻO ka Ultrasonic transducer kahi mea hoʻololi ikehu e hoʻololi i nā hōʻailona uila i nā hōʻailona acoustic a i ʻole nā hōʻailona acoustic i nā hōʻailona uila i loko o ka laulā kani ultrasonic. He mea koʻikoʻi ia i nā lako kani ultrasonic, no laila ʻaʻole ia i loko o ka mīkini transduction a i ʻole ke kaʻina hana Hoʻolālā a me nā ʻaoʻao ʻē aʻe i loaʻa ka nānā lōʻihi.
Nā palena hana o nā transducers kani ultrasonic
ʻO ka ultrasonic transducer kahi mea hoʻololi ikehu, a ʻo kāna wehewehe hana a me ka loiloi e koi ai i nā ʻāpana he nui. ʻO nā hiʻohiʻona hiʻohiʻona o ka ultrasonic transducer e pili ana i ka resonance frequency, frequency bandwidth, electromechanical coupling coefficient, electroacoustic efficiency, mechanical quality factor, impedance features, frequency Characteristics, directivity, transmitting and receiving sensitivity, etc. No ka loaʻa ʻana o nā transducers kani ultrasonic, pono kahi alapine ākea a me ka ʻike kiʻekiʻe a me ka hoʻonā. No laila, i ke kaʻina hana hoʻolālā kikoʻī o ka transducer, pono e hoʻokō ʻia nā palena kūpono o ka transducer e like me ka noi kikoʻī Hoʻolālā kūpono.
Kaʻina hana o ka ultrasonic transducer
ʻO nā transducers kani kani ka ʻōnaehana kaapuni, ka ʻōnaehana haʻalulu mechanical a me ka ʻōnaehana acoustic, a ʻo nā mea ʻekolu i hui pū ʻia i loko o kahi hui holoʻokoʻa i ka wā e hana ana ka transducer. Hoʻoholo kēia i ke ʻano noiʻi no ka hui ʻana o ka uila ʻO nā ʻano noiʻi o ka ʻepekema, mechanics, acoustics, etc., a ma o ka electro-mechanical-acoustic analogi, hiki i nā ʻekolu ke hoʻohana i kahi kiʻi electromechanical like ʻole a me nā hoʻohālikelike like e hana maʻalahi i ka noiʻi hohonu.
Ka ultrasonic generator hoohuli i ka 220V mains mana i kiʻekiʻe-frequency o keia manawa, a me ke kani ultrasonic transducer hoohuli i ka kiʻekiʻe-frequency o keia manawa i mechanical vibration, a laila, amplifies (hoemi) i ka amplitude ma o ka kani kani kani kani, a hope hoʻouna ia i ka mea paahana poo no ka hana. ʻElua mau ʻano o nā mea transducers kani ultrasonic: magnetostrictive a me piezoelectric ceramics.
Mea hoʻohui transducer
ʻElemu seramika piezoelectric waena
Nā uhi metala ma mua a ma hope
wili mua
Papa uila
Paipu hoʻopulapula
Hoʻopuka kēia ʻano transducer sanwiti i nā hawewe kani ultrasonic paʻa i ka wā e hoʻololi ai ka ukana, ʻo ia ke ʻano kumu a nui loa e loaʻa ai ka mana ultrasonic drive kumu. Wahi a nā hoʻolālā like ʻole, ʻo nā ʻano o nā transducers ultrasonic ka mea nui:
ʻAno kolamu (ʻano NTK)
ʻAno pū hoʻohuli (Benengxin type)
Ka uhi kua kila
ʻAno pahu alumini
ʻO nā mea transducers kani kani ka mea kūpono no ka hoʻoheheʻe ʻana i ke kani ultrasonic, ka ʻoki ʻana i ke kani ultrasonic, ka mālama ʻana i ka wai ultrasonic, ka hoʻoheheʻe ʻana o ka ultrasonic atomization a me ka hoʻoheheʻe ʻana o ka metala kani ultrasonic.
