Molao-motheo le ts'ebetso ea probe ea ultrasonic

1. Tlhahlobo ea ultrasonic ke eng

Probe e sebelisoang litekong tsa ultrasonic ke transducer e sebelisang phello ea piezoelectric ea thepa ho hlokomela phetoho ea matla a motlakase le matla a molumo.Karolo ea bohlokoa ea probe ke sephaphatha, e leng letlapa le le leng la kristale kapa polycrystalline le phello ea piezoelectric.Mosebetsi ke ho fetolela matla a motlakase le matla a molumo ho e mong.

2. Molao-motheo oa tlhahlobo ea ultrasonic

Probe e nang le li-wafer tse peli, e 'ngoe e le transmitter' me e 'ngoe e le moamoheli, e boetse e bitsoa probe e arohaneng kapa probe e kopaneng e habeli.The dual element probe e haholo-holo e entsoe ka socket, shell, residual layer, transmitting chip, receive chip, delay block, joalo-joalo E sebelisa paatsepama longitudinal leqhubu molumo oa lerata ho hlahloba workpiece.Ha ho bapisoa le li-probes tse otlolohileng, li-probes tse peli tse otlolohileng tsa kristale li na le bokhoni bo botle ba ho lemoha bakeng sa mefokolo e haufi-ufi;bakeng sa libaka tsa ho lemoha tse mahlahahlaha kapa tse kobehileng, li na le phello e ntle ea ho kopanya.

E sebelisoa lits'ebetsong tsa ho lemoha liphoso tsa semi-automatic kapa automated.Ha axis ea molumo oa molumo o hlahisoang ke probe e le perpendicular ho sebaka sa ho lemoha, leqhubu la longitudinal leqhubu le tobileng le hlahloba mosebetsi;lokisa molumo oa lekhalo la molumo oa probe ho theha sekhutlo se itseng ka sebaka sa ho lemoha.Molumo oa molumo o refracted ka segokanyimmediamentsi sa sebolokigolo pakeng tsa metsi le workpiece.Leqhubu la molumo oa leqhubu le tšekaletseng le hlahisoa ka har'a sesebediswa sa mosebetsi ho lekola mosebetsi.The plexiglass kapa e folisitsoeng epoxy resin ka pel'a chip ea probe e sebetsoa ho arc e itseng (spherical kapa cylindrical), 'me ho ka fumanoa probe ea ho qoelisoa ka metsi e shebaneng le ntlha kapa mola.

3. Mosebetsi oa probe ea ultrasonic

1) Fetola maqhubu a molumo a khutlang hore e be maqhubu a motlakase;

2) Ke ho laola tataiso ea phatlalatso ea leqhubu la ultrasonic le tekanyo ea matla a matla.Ha angle ea ketsahalo ea probe e fetoloa kapa angle ea phallo ea leqhubu la ultrasonic e fetoloa, matla a ka sehloohong a leqhubu la molumo a ka kenngoa bohareng ka li-angles tse fapaneng kapa tataiso ea leqhubu la molumo e ka fetoloa ho ntlafatsa qeto. .Sekhahla;

3) Ho fihlela phetoho ea waveform;

4) Ke ho laola lebelo la ho sebetsa, le loketseng maemo a fapaneng a ho sebetsa.
