Cov Lus Nquag Nug ntawm Ultrasonic Transducers
Nquag cov lus nug txog ultrasonic transducers
1. Thaum lub ultrasonic vibrator tseem ntub, koj tuaj yeem siv megohmmeter los kuaj xyuas cov ntsaws txuas nrog ntawm lub tshuab hloov pauv. Txheeb xyuas lub rwb thaiv tsev tiv thaiv tus nqi los txiav txim siab qhov teeb meem. Feem ntau, kev tiv thaiv rwb thaiv tsev yuav tsum muaj qhov ntau dua 5 megohms. Yog hais tias lub rwb thaiv tsev tiv thaiv tus nqi tsis tau nce mus txog, lub tshuab hloov ua feem ntau yog noo. Koj tuaj yeem muab lub tshuab hloov pauv kom tag nrho (tsis suav nrog lub plhaub-plhaub yas) rau hauv qhov cub thiab teeb nws ntawm 100 ° C rau 3 teev lossis siv lub tshuab ziab plaub hau kom tshem tawm ya raws rau tus nqi tsis kam. Kom deb li deb.
2. Cov tshuab hluav taws xob hloov tshuab hluav taws xob ib qho tsis tuaj yeem thiab cov khoom siv ceramic tawg. Nws tuaj yeem tshawb xyuas nrog lub ntsej muag liab qab thiab ib lub megohmmeter. Feem ntau, raws li kev ntsuas kub ntxhov, tus kheej lub vibrators puas ntsoog tuaj yeem raug kaw tau yam tsis muaj kev cuam tshuam rau kev siv lwm lub vibrators.
3. Lub tshuab ua kom lub zog qis dua. Peb lub tshuab hloov pauv txais ob qhov kev lav lus ntawm cov txheej txheem ntawm kev ua cementing thiab ntsia hlau nrawm, uas yuav tshwm sim nyob rau hauv ib txwm muaj xwm txheej.
4. Lub stainless hlau kev co lub ntsej muag yog qhov perforated. Feem ntau, kev co lub ntsej muag perforation yuav tshwm sim thaum lub tshuab txhais khoom siv rau 10 xyoo ntawm qhov kev thauj khoom tag nrho.
Ultrasonic transducer
Cov ultrasonic transducer suav nrog lub plhaub (1), ib txheej txheej los yog lub qhov rai (2), ib qho piezoelectric ceramic disc transducer (3), ib qho thaub qab (4), thiab ib qho xov hluav taws xob (5), uas yog tus cwj pwm hauv nws kuj suav nrog Cymbal array receiver, uas muaj li ntawm cov hlau lead-tawm cable (6), 8-16 Cymbal hloov khoom (7), cov nplhaib hlau (8), (9) thiab rubber gasket (10); Cymbal array receiver tau nyob rau ntawm disc saum cov piezoelectric transducer 3; lub piezoelectric ceramic disc transducer yog siv los ua cov theem pib ultrasonic transducer, uas xa thiab tau txais cov cim ultrasonic; lub Cymbal array receiver nyob rau ntawm disc piezoelectric transducer, Raws li lub tshuab txais ultrasonic, nws yog siv los txais Doppler ncha cim sab nraud sab nraud ntawm cov zaus sib txuas ntawm cov disc transducer.
