I. Kuyini i-ultrasound?

Amagagasi e-Ultrasonic ayindlela esebenzisa amandla akhiqizwa ukudlidliza okuvama kakhulu ukuze asebenze ebusweni bento yokusebenza, ngaleyo ndlela kufezwe ukuhlanganiswa kwezingxenye zensimbi ndawonye.

II. Isimiso Sokusebenza Samagagasi E-Ultrasonic

1. Amandla kagesi aguqulwa abe ukudlidliza komshini okuvamise kakhulu, okube sekudluliselwa embotsheni yokushisela ngekhanda lokushisela elilungiswe kahle nge-acoustic. Izingcezu zokusebenza eziphezulu nezingezansi ziyakhuhlana ngaphansi kwemijikelezo yokucindezela izikhathi ezingu-20,000 noma ezingu-40,000 ngomzuzwana. Umphumela ohlangene wokudlidliza okuvamise kakhulu kanye nokucindezela kusabalalisa ungqimba oluncane lwezinto kanye nama-oxide ebusweni bezingcezu zokusebenza, kwakha i-weld yokusabalalisa ehlanzekile nelawulekayo. Ngokuhlanganiswa kwama-athomu phakathi kwezingcezu zokusebenza, ungqimba lokuhlanganisa insimbi oluthembekile ekugcineni luyakhiwa.
2. Ugesi onamaza aphansi uguqulwa ube ugesi onamaza aphezulu yijeneretha. Ugesi onamaza aphezulu ube usuguqulwa ube ukudlidliza komshini yi-transducer. I-modulator ye-amplitude kanye nekhanda lokushisela banesibopho sokulungisa i-amplitude yokudlidliza. Ngaphansi kwengcindezi ethile engaguquki, izakhiwo zama-molecule ebusweni bensimbi ziyagudlana futhi zishayisane, zifinyelele ekungeneni kwama-molecular, ngaleyo ndlela ziqedele ukushibiliza.

Ulwazi oluyisisekelo kanye nokuxazulula izinkinga ze-ultrasound

III. Amaphutha Avamile Ekushiseni Kwe-Ultrasonic

(a) Ukushisela okungaphelele

1. Amandla okukhipha ukushisela anganele: ukucindezela okunganele, ubukhulu obunganele, noma isisekelo asikaqini kahle.
2. Amandla okushisela anganele: Ifomula yokubala amandla okukhiphayo yi-E=P×T=F×V×T=μN×A×f×T (lapho u-E engamandla, u-P engamandla, u-V engajubane, u-μ uyi-coefficient of friction, u-N uyingcindezi, u-A uyi-amplitude, u-f uyimvamisa, kanye no-T isikhathi). Amandla anganele azoholela ekushiseleni okungekuhle.
3. Izingqimba zikawoyela noma ze-oxide ebusweni bezinto zingathinta umphumela wokubopha kwe-welding.
4. Uma amazinyo ebukhali kakhulu, angangena kalula ekushiseni ngesikhathi sokushisisa.
5. Ubuso be-weldment bune-coating yezinto ezingafaneleki ukushiselwa kwe-ultrasonic.
6. Izinto ezishintshwayo azifaneleki ukushintshwa nge-ultrasonic.

(ii) Isisekelo sekhanda lokushisela

Imbangela : Lapho ikhanda lokushisela noma isisekelo sokushisela sithintana nezinto, kukhiqizwa amazinga okushisa aphezulu kakhulu, okubangela ukungena kwama-molecule phakathi kwezinto kanye nekhanda lokushisela noma isisekelo, okuholela ekunamatheleni.

Isixazululo :

1. Hlola amazinyo ekhanda kanye nesisekelo sokushisela. Uma ukuguguleka kukhulu, kuzokwenza izinga lokushisa lenyuke, futhi kudinga ukuxazululwa ngesikhathi.
2. Ngenkathi kuqinisekiswa imiphumela yokushisela, amandla angandiswa ngokufanele futhi isikhathi sokushisela sifinyezwe ukuze kuncishiswe ukushintshana kwamandla ngokweqile phakathi kwekhanda lokushisela nezinto ezisetshenziswayo.

(iii) Ukushisela imifantu

1. Ukuqhekeka eduze kwejoyinti lokushisela: Lapho kushiselwa izendlalelo eziningi zezinto, unqenqema lwejoyinti lokushisela lwakha umthambeka. Lapho ikhanda lokushisela lidlidliza, lizosebenzisa amandla okudonsa onqenqemeni, okungadala ukuqhekeka kalula.
2. Isixazululo : Yenza ukwelashwa okukhethekile emaphethelweni ejoyinti lokushisela ukuqinisekisa ukusatshalaliswa kokucindezeleka okulinganayo futhi unciphise amandla okudonsa akhiqizwa ukudlidliza.
3. Imifantu eduze kwejoyinti le-solder: Ukudlidliza kwekhanda le-soldering kubangela ukuthi izinto zihambe ziye emuva naphambili. Isibonelo, uma i-aluminium foil ixhunywe ebhethrini, ukudonsa kungabangela ukuphuka kalula.
4. Izixazululo : ① Shintsha indlela iphethini yamazinyo (isb., sebenzisa amaphethini avundlile) ukuze ulungise indlela yamandla ezintweni; ② Yelula ithebhu ngokufanele ukuze udale isikhala se-buffer phakathi kwebhethri kanye nejoyinti le-solder.

(iv) Ukuguquguquka okukhulu kwamandla okukhipha

Isizathu : Kunezici eziningi ezithinta amandla okukhipha, futhi zidinga ukuhlolwa ngasinye ngasinye.

Isixazululo :

1. Hlola ukufakwa kweyunithi kathathu, hlola ukuthi akukho monakalo, bese uyihlanganisa kabusha uma kudingeka.
2. Hlola ukuthi izikulufu eziyisisekelo ziqiniswe kahle.
3. Hlola izikhala endaweni lapho kukhona khona i-base clamp.
4. Hlola izinto zokushisela ukuqinisekisa ukuthi izindawo zokushisela ziyafana isikhathi ngasinye.
5. Hlola ubuso bento ukuze kutholakale ukuthi ayinawo yini umoya noma amabala kawoyela.
6. Qinisekisa ukuthi imininingwane yezinto ezingenayo iyahambisana (lapho ukushaywa kwekhanda lokushisela kulungisiwe, umehluko ekujiyeni nasekuqineni kwezinto kuzobangela ukuguquguquka kwamandla okukhipha).
7. Hlola ukuzinza komoya wefektri bese ubheka ukuthi kukhona yini ukuguquguquka kwesilinganiso sokucindezela komoya ongenayo.
8. Hlola ukuthi ukuphuma kwe-ultrasonic kwebhokisi lokunikezwa kwamandla kuzinzile yini.

(v) Ukulayisha ngokweqile

Izimbangela zifaka izimo ezimbili: ukugcwala kwamandla kanye nokugcwala kwamavayisi amaningi.

Isixazululo :

1. Nciphisa imingcele yokushisela ngokufanele.
2. Nciphisa ukujula kokwehla kwekhanda lokushisela ukuqinisekisa ukuthi kugcinwa igebe elithile phakathi kwekhanda lokushisela kanye nesisekelo.
