Dacheng Precision esale e ikemiselitse ho etsa lipatlisiso le nts'etsopele ea mahlale a macha. Ntle le litharollo tse kaholimo tse sa senyeheng, e boetse e nts'etsapele theknoloji ea ho lekanya botenya ba ultrasonic. Ha ho bapisoa le litharollo tse ling tsa tlhahlobo, tekanyo ea botenya ba ultrasonic e na le litšobotsi tse latelang.
3.1 Molao-motheo oa tekanyo ea botenya ba Ultrasonic
Ultrasonic thickness gauge e lekanya botenya bo ipapisitse le molao-motheo oa mokhoa oa ultrasonic pulse reflection. Ha pulse ea ultrasonic e hlahisoang ke probe e feta nthong e lekantsoeng ho fihlela li-interfaces tsa thepa, leqhubu la pulse le bontšoa morao ho probe. Botenya ba ntho e lekantsoeng bo ka khethoa ka ho lekanya ka nepo nako ea ho ata ha ultrasonic.

①Ultrasonic wave e na le ho kenella ka matla ka lebaka la bolelele ba eona bo khuts'oane, 'me e sebetsa mefuteng e mengata ea lisebelisoa.
② Bolo ea molumo oa Ultrasonic e ka tsepamisoa ka tsela e itseng, 'me e tsamaea ka tsela e otlolohileng ho ea bohareng, e nang le tataiso e ntle.
③ Ha ho na lebaka la ho tšoenyeha ka taba ea polokeho hobane ha e na mahlaseli.
Leha ho le joalo, ho sa tsotellehe taba ea hore tekanyo ea botenya ba ultrasonic e na le melemo e joalo, ha e bapisoa le mekhoa e mengata ea ho lekanya botenya eo Dacheng Precision e seng e tlisitse 'marakeng, tšebeliso ea tekanyo ea botenya ba ultrasonic e na le mefokolo e latelang.
3.3 Meeli ea ts'ebeliso ea tekanyo ea botenya ba ultrasonic
① Ultrasonic transducer: ultrasonic transducer, ke hore, ultrasonic probe e boletsoeng ka holimo, ke karolo ea mantlha ea litekanyo tsa tlhahlobo ea ultrasonic, tse khonang ho fetisa le ho amohela maqhubu a pulse. Lipontšo tsa eona tsa mantlha tsa makhetlo a ho sebetsa le ho nepahala ha nako li khetholla ho nepahala ha tekanyo ea botenya. Theko ea hona joale e phahameng ea ultrasonic transducer e ntse e itšetlehile ka thepa e tsoang linaheng tse ling, eo theko ea eona e leng theko e boima.
②Material uniform: joalo ka ha ho boletsoe melaong ea mantlha, ultrasonic e tla bonts'oa morao ho li-interfaces tsa thepa. Ponahalo e bakoa ke liphetoho tsa tšohanyetso tsa acoustic impedance, 'me ho ts'oana ha "acoustic impedance" ho khethoa ke ho lumellana ha lintho. Haeba thepa e lokelang ho lekanyetsoa e sa tšoane, letšoao la echo le tla hlahisa lerata le leholo, le amang liphello tsa tekanyo.
③ Bokhopo: bokhopo bo kaholimo ba ntho e lekantsoeng bo tla baka molumo o tlase, kapa esita le ho sitoa ho amohela lets'oao la echo;
④Mocheso: moelelo oa ultrasonic ke hore ho sisinyeha ha mechine ea likaroloana tse mahareng ho phatlalatsoa ka mokhoa oa maqhubu, a ke keng a arohanngoa le ho sebelisana ha likaroloana tse mahareng. Pontšo ea macroscopic ea ho sisinyeha ha mocheso oa likaroloana tse mahareng ke mocheso, 'me ho sisinyeha ha mocheso ka tlhaho ho tla ama tšebelisano lipakeng tsa likaroloana tse mahareng. Kahoo mocheso o na le litlamorao tse kholo ho liphetho tsa tekanyo.
Bakeng sa tekanyo e tloaelehileng ea botenya ba ultrasonic e ipapisitseng le pulse echo molao-motheo, mocheso oa matsoho a batho o tla ama mocheso oa probe, kahoo o lebisa ho hoholeha ha ntlha ea zero ea gauge.
⑤Botsitso: leqhubu la molumo ke ho sisinyeha ha mechine ea likaroloana tse mahareng ka mokhoa oa ho phatlalatsoa ha maqhubu. E ka hlaseloa ke tšitiso ea ka ntle, 'me pontšo e bokelitsoeng ha e tsitsa.
⑥Coupling medium: ultrasonic e tla fokotseha moeeng, ha e ntse e ka ata hantle ka metsi le lintho tse tiileng. Bakeng sa ho amohela lets'oao la echo hamolemo, hangata mochini o kopanyang metsi o eketsoa lipakeng tsa probe ea ultrasonic le ntho e lekantsoeng, e sa lokeleng ho nts'etsopele ea lenaneo la tlhahlobo ea othomathiki ea inthaneteng.
Lintlha tse ling, tse kang ultrasonic phase reversal kapa khothatso, curvature, taper kapa eccentricity ea bokaholimo ba ntho e lekantsoeng e tla susumetsa liphetho tsa tekanyo.
Ho ka bonoa hore tekanyo ea botenya ba ultrasonic e na le melemo e mengata. Leha ho le joalo, hajoale e ke ke ea bapisoa le mekhoa e meng ea ho lekanya botenya ka lebaka la mefokolo ea eona.

Lintlha tsa liteko li hlahisoa ka mokhoa oa A-scan le B-scan. Ho A-scan, X-axis, e emela nako ea phetisetso ea ultrasonic le Y-axis e emela matla a maqhubu a bonahatsoang. B-scan e bonts'a setšoantšo sa mahlakore a mabeli sa profaele e bapileng le tataiso ea ho phatlalatsoa ha lebelo la molumo le perpendicular ho bokaholimo bo lekantsoeng ba ntho e tlas'a teko.
Ho tloha ho A-scan, ho ka bonoa hore amplitude ea leqhubu la pulse le khutliselitsoeng mateanong a graphite le foil ea koporo e phahame haholo ho feta ea maqhubu a mang. Botenya ba ho roala ha graphite bo ka fumanoa ka ho bala acoustic-path ea ultrasonic wave ka har'a graphite medium.
Kakaretso ea linako tse 5 tsa data e ile ea lekoa libakeng tse peli, Point1 le Point2, le acoustic-path ea graphite ho Point1 e ne e le 0.0340 rona, le acoustic-path ea graphite ho Point2 e ne e le 0.0300 rona, ka mokhoa o nepahetseng oa ho pheta-pheta.
