Mfundo ya Akupanga Kuyeretsa

Mafupipafupi a ultrasonic wave ndi kuchuluka kwa kugwedezeka kwa gwero la mawu.Zomwe zimatchedwa kugwedezeka pafupipafupi ndi kuchuluka kwamayendedwe obwereza pamphindikati, gawolo ndi Hertz, kapena Hertz mwachidule.Wave ndi kufalikira kwa kugwedezeka, ndiko kuti, kugwedezeka kumafalikira pafupipafupi koyambirira.Chifukwa chake, kuchuluka kwa mafunde ndi kuchuluka kwa kugwedezeka kwa gwero la mawu.Mafunde amatha kugawidwa m'mitundu itatu, yomwe ndi mafunde a infrasonic, mafunde acoustic, ndi mafunde akupanga.Mafupipafupi a mafunde a infrasound ali pansi pa 20Hz;pafupipafupi mafunde amawu ndi 20Hz ~ 20kHz;pafupipafupi mafunde akupanga ndi pamwamba 20kHz.Mwa iwo, mafunde a infrasound ndi ma ultrasound nthawi zambiri samamveka m'makutu a anthu.Chifukwa cha kuchuluka kwafupipafupi komanso kutalika kwafupipafupi, mafunde a ultrasonic ali ndi njira yabwino yopatsirana komanso kuthekera kolowera mwamphamvu.Ichi ndichifukwa chake makina otsuka akupanga amapangidwa ndikupangidwa.

mfundo yoyambira:

Chifukwa chomwe akupanga zotsuka amatha kuchita nawo ntchito yoyeretsa dothi amayamba chifukwa cha izi: cavitation, acoustic flow, acoustic radiation pressure ndi acoustic capillary effect.

Panthawi yoyeretsa, pamwamba pa dothi lidzawononga chiwonongeko, peeling, kupatukana, emulsification ndi kusungunuka kwa filimu yadothi pamwamba.Zinthu zosiyanasiyana zimakhala ndi zotsatira zosiyana pa makina ochapira.Akupanga zotsukira makamaka kudalira kugwedezeka kwa cavitation thovu (unexploded cavitation thovu) kwa anthu dothi kuti si kwambiri zolimba Ufumuyo.Pamphepete mwa dothi, chifukwa cha kugwedezeka kwamphamvu ndi kuphulika kwa thovu zowonongeka, mphamvu yolumikizana pakati pa filimu yadothi ndi pamwamba pa chinthucho imawonongeka, yomwe imakhala ndi zotsatira za kung'amba ndi kupukuta.Acoustic poizoniyu kuthamanga ndi lamayimbidwe capillary zotsatira kulimbikitsa kulowerera kwa kusamba madzi mu ting'onoting'ono recessed pamalo ndi pores a chinthu kutsukidwa, ndi otaya phokoso akhoza imathandizira kulekana kwa dothi padziko.Ngati kumatira kwa dothi kumtunda kuli kolimba, mafunde ang'onoang'ono owopsa omwe amapangidwa ndi kuphulika kwa kuwira kwa cavitation ayenera kugwiritsidwa ntchito kukoka dothi pamtunda.

The akupanga kuyeretsa makina makamaka amagwiritsa "cavitation zotsatira" wa madzi-pamene akupanga mafunde kunyezimira mu madzi, madzi mamolekyulu nthawi zina anatambasula ndipo nthawizina wothinikizidwa, kupanga ambirimbiri ting'onoting'ono cavities, otchedwa "cavitation thovu".Pamene kuwira kwa cavitation kuphulika nthawi yomweyo, mafunde amtundu wa hydraulic shock wave (kupanikizika kumatha kufika pamtunda wa 1000 kapena kuposerapo) kudzapangidwa.Pansi pa mphamvu yosalekeza ya kukakamizidwa uku, mitundu yonse ya dothi yomwe imamatira pamwamba pa chogwirira ntchito idzachotsedwa;pa nthawi yomweyo, akupanga yoweyula Pansi pa zochita, ndi pulsating yogwira mtima wa kuyeretsa madzi kwambiri, ndi kuvunda, kubalalitsidwa ndi emulsification ndi inapita patsogolo, potero kuyeretsa workpiece.

Ubwino woyeretsa:

a) Kuyeretsa bwino, ukhondo wapamwamba komanso ukhondo wamtundu uliwonse wazinthu zonse;

b) Liwiro loyeretsera limakhala lachangu ndipo magwiridwe antchito amapangidwa bwino;

c) Palibe chifukwa chokhudza madzi oyeretsera ndi manja a anthu, omwe ali otetezeka komanso odalirika;

d) Mabowo akuya, ming'alu ndi magawo obisika a workpiece amathanso kutsukidwa;

e) Palibe kuwonongeka pamwamba pa workpiece;

f) Sungani zosungunulira, mphamvu zotentha, malo ogwirira ntchito ndi ntchito, ndi zina.
