I-China eshibhile intengo i-ultrasonic drill ethengiswayo - Imvamisa ephezulu yokuhambisana 1KhzZ Ultrasonic Imperance Analyzer - Powersonic

Imvamisa ephezulu yokuhlangana kwe-ultrasonic impedance analyzer ye-ultrasound transcucers

KanjaniUkuhlola ukusebenza kwe-transcucer ye-ultrasonic?

Ukuhlola ukusebenza kohlelo lokudlidliza lwe-ultrasonic, kuyadingeka ukuhlaziya kusuka ezicini ezimbili: amapharamitha nama-curve avumayo:

1) Amapharamitha:

Ukuhlaziywa kwe-Impedance kungasetshenziswa ukuhlola ukusebenza kwamadivayisi ahlukahlukene afana namashidi we-pezoelectric ceramic, ama-pliezoelectric transfer, nezinhlelo zonke zokudlidliza (ama-transcutivers kanye nezimpondo, isikhunta). Ukuhlaziywa kwemishini yedivaysi ye-ultrasonic nge-analyzer ye-Impedance, amapharamitha abaluleke kakhulu anje:

FS: Imvamisa ye-Mechan Resonant, ie imvamisa yokusebenza yohlelo lokudlidliza, kufanele isondelene nenani elilindelekile ngangokunokwenzeka ekwakhiweni futhi kufanele ihambisane nephuzu lokusebenza lokuhlinzekwa kwamandla.

Ngomshini wokuhlanza, ukukhuphuka imvamisa yokuguquguquka kwe-resonant ye-vibrator, okungcono.

Kuma-welders epulasitiki noma imishini ye-ultrasonic, uma uphondo noma umklamo wokubumba awunangqondo, imvamisa yokuvuselela i-vibrator izophambuka endaweni yokusebenza.

I-R1: Ukumelana nokwashukumisayo, ukumelana nochungechunge lochungechunge lwePiezoelectric Bubrators, okuncane okungcono ngaphansi kwezimo ezifanayo zokusekelwa. Ngokuhlanza noma ukudliwa kwe-vibrators, ngokuvamile kuphakathi5 ω no-20 ω. Uma kukhulu kakhulu, uhlelo lwe-vibrator noma uhlelo lokudlidliza luzoba nezinkinga, njengokuphambanisa kwesekethe noma ukuguqulwa okuphansi, kanye nokuphila okufushane kwe-vibrator.

QM: I-Mechanical Fork Factor, enqunywe yindlela yejika le-reakrance, qm = FS / (F2 - F1), i-HI-IGIGER the QM, okungcono, ngoba i-QM ephezulu, iphakeme ukusebenza kahle kwe-vibrator; Kepha i-QM kumele ihambisane nokunikezwa kwamandla, inani le-QM liphezulu kakhulu ukuhanjiswa kwamandla akuhambelani.

Ngokuhlanza i-vibrator, inani le-QM eliphakeme, elingcono. Ngokuvamile, i-qm yesidlidlizi sokuhlanza kufanele ibe phakathi kuka-500 no-1000. Uma kuphansi kakhulu, ukusebenza kahle kwe-vibrator kuphansi. Uma kuphezulu kakhulu, ukunikezwa kwamandla akunakufaniswa.

Ngokufaka i-ultrasonic ukuthutha noma ama-machishini, inani le-qm le-vibrator ngokwalo livame cishe ngo-500 ~ 1000, futhi lonke uhlelo lungu-1500 ~ 3000. Uma kuphansi kakhulu, ukusebenza kahle kwe-vibration kuphansi, kepha akunakuphakama kakhulu, ngoba kuphakama i-QM ephakeme, okuwukuthi, ukunikezwa kwamandla kunzima ukulingana endaweni yemvamisa ye-resonant, futhi idivaysi ayikwazi ukusebenza.

I-CT: I-Capacitance yamahhala, inani lamakhono ledivaysi ye-piezoelectric at 1 khz. Leli nani liyahambisana nenani elinganiswe ngamamitha we-capcacitance adijithali. Leli nani likhipha i-capacitor enamandla c1 ukuze uthole i-capcacitance yangempela ye-c0, c0 = ct - C1. Lapho usebenzisa, ibhalansi ye-C0 nge-intanethi.

Ekwakhiweni kwesifunda komshini wokuwasha noma ngomshini wokucubungula i-ultrasonic, ukulinganisa kahle i-C0 kungakhulisa isici samandla okunikezwa kwamandla. Kunezindlela ezimbili zokusebenzisa ibhalansi ye-inductor, ukuhleleka okuhambisanayo kanye nokuhlelwa kochungechunge.

I-FP: Imvamisa ye-anti - imvamisa ye-resonance, imvamisa evumayo yegatsha elihambisanayo le-piezoelectric vibrator. Ngalesi sikhathi, i-zmax ye-impedance ye-piezoelectric vibrator enkulu kunazo zonke. Uma i-anti - i-resonant impedance zmax iphansi, i-vibrator inenkinga.

2) ihluzo

I-Impedance Analyzer ihlinzeka ngezinhlobo ezinhlanu zokudidiyela imidwebo yengqondo, kanye nomdwebo wesimo somqondo we-logarithmic unokubaluleka okubalulekile kokutholwa kwamadivayisi we-piezoelectric. Ukusebenza kokudlidliza kwe-viezoelectric vibrator noma uhlelo oludlidliza kungahlulelwa ngqo ngegrafu ye-logarithmic, okubonakalayo futhi okusebenzayo.

Ngaphansi kwezimo ezijwayelekile, umbuthano wokuvumisa kanye nejika lokuphatha njengoba kuboniswe kulokhu okulandelayo.

Ukwenza:

Umbuthano we-Admittance uyindilinga eyodwa, futhi igrafu ye-logarithmic ine-pair yamanani aphansi nje futhi aphezulu:

Insizakalo nokuthumela
