Dab tsi yog vim li cas vim li cas ultrasonic pwm ua kub sai?

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ultrasonic vuam yog siv kaum tawm txhiab qhov kev vibrations siab ib ob mus rau qhov chaw sib cuag ntawm ob qhov kub-melt plastics los ntawm pwm. ua ke rau hauv ib qho.

Yog li ntawd, thaum lub tshuab vuam ultrasonic ua haujlwm, nws yog qhov yuav tsum tau ua kom cov pwm yuav kub, tsuav nws qhov kub tsis tshaj 80 degrees, nws tuaj yeem tso cai ua haujlwm ib txwm.

Yog tias qhov kub ntawm cov pwm ua haujlwm siab tshaj 80 degree, nws txhais tau hais tias muaj teeb meem hauv kev tsim thiab tsim cov pwm ultrasonic. Cov laj thawj tuaj yeem pom los ntawm peb yam:

1. Ultrasonic zaus tsis raug, ua rau tsis muaj zog hloov dua siab tshiab efficiency, tsis muaj zog tso zis zog thiab siab kub tsim;

2. Kev koom tes ntawm ultrasonic transducer thiab pwm tsis tacit, thiab nws tsis ruaj khov thiab ua kom sov thaum ua haujlwm;

3. Qhov teeb meem ntawm pwm nws tus kheej, qhov tsim tsis tsim nyog ntawm cov pwm los yog kev kho cua sov tsis tsim nyog yuav ua rau muaj kev kub ntxhov tam sim no thiab siab impedance, uas ua rau cov cua sov tsim.
