Daim ntawv khob tshuab ultrasonic ib txwm hlawv thyristor. Yuav kho li cas?
Dec 02, 2022
Yog tias daim ntawv khob tshuab ultrasonic ib txwm hlawv thyristors, koj yuav tsum ua tib zoo xyuas seb puas muaj teeb meem nrog lub transducer thiab cov nqaj. Yog tias tsis muaj teeb meem, koj tuaj yeem kho nws raws li kuv txoj kev. Yog tias koj tseem tuaj yeem kho tsis tau, nws kwv yees tias muaj qee yam tsis zoo ntawm lub rooj tsavxwm kev co, uas xav tau peb tus kws kho mob kom them rau nws.
1, hloov lub triode, sim ua kom nws tsis zoo ib yam nrog rau lwm yam triodes.
2. Tshawb xyuas lub transducer thiab amplitude transformer (uas yog, amplitude transformer) kom pom tias lawv puas lawm. Saib seb puas muaj qhov tawg ntawm lub ntsiab hlau thaiv, thiab yog tias muaj kev tawg lossis tawg hauv daim ntawv piezoelectric ceramic ntawm cov transducer.
3. Xyuas seb qhov kev sib txuas ntawm lub transducer thiab lub horn yog nruj. Yog tias nws xoob, siv cov cuab yeej los zawm nws.
4. Thaum kuaj ultrasound, nco ntsoov txuas lub transducer nrog lub horn, thiab tsis tas yuav muaj pwm. Thaum nias qhov hloov pauv, nws yuav tsum tau tso tawm ib zaug, thiab lub sijhawm yuav tsum tau tswj tsis pub dhau 1 thib ob. Saib qhov pointer ntau ntawm amplitude meter, thiab tom qab ntawd ua qhov kev hloov pauv zaus.
