Mafupipafupi omwe makina akupanga kuwotcherera ndi 15khz ndi 20khz omwe akupanga pulasitiki kuwotcherera makina. Kutalika kwafupipafupi kwa akupanga, kumakhala koyenera kuwotcherera molondola, koma mphamvu zazing'ono mphamvu, ndizocheperako matalikidwe. Otsatirawa akufotokoza kusiyana pakati pa makina akupanga kuwotcherera 15khz ndi 20khz:
Pamene pafupipafupi akupanga amakhala otsika, phokoso limapangidwa. Pafupipafupi pamakhala poyerekeza ndi 20 khz, phokoso limakhala lalikulu kwambiri panthawi yopanga ma ultrasonic. Pazinthu zamapulasitiki zokhala ndi zowongolera bwino kwambiri, zimachulukanso, zimakhala bwino. Chifukwa chake, makina akupanga kuwotcherera a 20khz kapena kupitilira apo ndioyenera kutsata, pulasitiki yopepuka, yopepuka kwambiri, monga khadi ya SD, kapena zinthu zokhala ndi kristalo mkati mwazogulitsazo; 15khz makina akupanga kuwotcherera ndi kosavuta kukulitsa ndipo ali wokulirapo matalikidwe. Ndioyenera kuwotcherera zazikulu, zovuta kuzimitsa, zopangira pulasitiki;
Kachiwiri, kukula kwa 15khz ndi 20khz akupanga nkhungu sikusinthanso. Kutalika kwa 15khz akupanga nkhungu nthawi zambiri kumakhala pafupifupi 17cm, pomwe 20khz akupanga nkhungu ndi pafupifupi 12.5cm kutalika.
Apanso, makina opangira pulasitiki a 15khz amatha kutulutsa zida zokulirapo, ndipo mphamvu imatha kugawidwa 2600w / 3200w / 4200w. Makina opangira pulasitiki a 20khz akupanga ndi 900W - 2000w, mphamvu ndi yaying'ono, ndipo kukula kwa chinthu chotheka ndichochepa.
