Txhawb kev txiav txim siab zoo: ultrasonic lawv yog tsim los ntawm ultrasonic generator thiab ultrasonic transducer, ultrasonic transducer yog ua los ntawm cov hlau lead zirconate taneate piezoelectric ceramic khoom sandwich transducer, piezoelectric ceramic khoom muaj qhov hloov ntawm qhov tshwm sim hauv hluav taws xob, nyob hauv qhov kev txiav txim ntawm alternating hluav taws xob teb transducer ua rau kev sib tw txhua yam.
Cov xwm txheej ntawm lub cev ultrasonic: tam sim no ntawm cov khoom qub (transducer + transformer) yog 0.3A ~ 0.8a, thiab cov amplitude 1% ~ 10%.
Hom teeb meem thiab cov kev daws hauv ultrasonic systems:
1. Lub phenomenon ntawm loj tam sim no, loj amplitude thiab screaming yog pom nyob rau hauv qhov chaw txiav.
Tshuaj:
1. Kho qhov kev ntsuas ntawm lub dav hlau kom txog thaum uas tam sim no thiab qhov siab tau hloov mus rau qhov qis tshaj, ces kho qhov siab ntawm qhov siab mus rau 1% siab tshaj qhov qub;
2. Thaum kho qhov teebmeem tsis daws qhov teebmeem no, lub tsev nyob thiab HORN raug puas tsuaj ;
2. Tam sim no ntawm lub voj voog ntau dhau saum toj rooj.
Tov: xyuas seb puas yog HORN, transformer thiab transducer muaj tawg. Yog tias muaj kab tawg, nws txhais tau hais tias lub vibration puas lawm. Yog tias tsis muaj cov keej, HORN raug tshem tawm thiab tig mus rau resonance, uas qhia tau hais tias HORN tawg.
3. Thaum txiav cov ntaub, tam sim no nws yog qhov qub, tab sis muaj suab txawv txav.
Tshuaj:
1. Kuaj xyuas seb cov oscillators (tshwj xeeb yog HORN) raug rau lwm cov khoom;
2. Ntsuas lub hau ntswj nrog lub paj log thiab kev sib tw hauv lub paj log;
3 txawm tias cov gongs tau loosened los yog puas yog cov gongs tau tawg;
Seb puas muaj cov pob hauv qhov chaw;
4. Tam sim no hloov ntawm lub vibration box tsis kaj.
Tshuaj:
1. Kuaj xyuas seb lub voj voos uas muaj kev vibration yog powered by multimeter.
2. Xyuas seb cov hlau tau raug kub hnyiab, thiab yog tias muaj kev tawg, ob nqe lus nug raug qhia:
A. Yog tias lub vibrator tawg, siv qhov txheej ntawm oscillators mus rau lub voj voos kom muaj qhov ntsuas (qhov kev kuaj hom qauv SIV thib ob tov los kuaj xyuas);
B. txheeb xyuas kev txhim kho lub thawv, xub xyuas seb lub hwj huam amplifier pawg hlawv tawm, thiab mam li xyuas seb puas xa co phaj hlawv, qhov no yog: nrog cov plaub hau kev vibration ntawm lub hwj huam amplifier phaj, kev co phaj, nrog rau qhov teeb meem ntawm lub zog lub thawv hwj huam amplifier phaj, kev phais kev siv los txhom qhov kev hloov chaw), los hloov lub fuse (5 a).
