Cov ntaub ntawv ultrasonic transducer-Altrasonic
Ultrasonic transducer tuaj yeem hais tias yog tus tub ntxhais tseem ceeb ntawm txhua yam ntawm ultrasonic khoom siv. Hauv cov lus yooj yooj yim, ultrasonic transducer yog lub zog hloov hluav taws xob uas tuaj yeem hloov hluav taws xob ntau hauv tshuab hluav taws xob rau hauv kev siv hluav taws xob. Lub piezoelectric nyhuv ntawm cov khoom hloov cov teeb liab hluav taws xob rau hauv kev siv tshuab kev co. Nws lub luag haujlwm yog hloov cov kev nkag ntawm hluav taws xob rau hauv kev siv lub tshuab hluav taws xob (ultrasound) thiab tom qab ntawd xa nws tawm, thaum noj ib feem me me ntawm lub zog los ntawm nws tus kheej. Lub tshuab hloov pauv muaj lub plhaub, txheej txheej sib txuam, ib qho piezoelectric ceramic disc transducer, rov qab, cov hlau lead-tawm cable thiab Cymbal array receiver. Lub piezoelectric ceramic disc transducer yog ua los ntawm PZT-5 piezoelectric cov ntaub ntawv polarized nyob rau hauv cov kev taw qhia tuab. Cymbal array receiver muaj 8-16 Cymbal hloov tsheb, ob txoj hlua hlau thiab roj hmab txuas. Ultrasonic transducer, suav nrog tsev nyob (1), txuam txheej los yog acoustic lub qhov rai (2), piezoelectric ceramic disc transducer (3), thaub qab (4), txhuas lub xov tooj (5), yam ntxwv hauv nws kuj suav nrog Cymbal array receiver, uas yog tsim ntawm cov hlau lead-out cable (6), 8-16 Cymbal transducers (7), hlau nplhaib (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. Feem ntau tsim nyog rau cov khoom siv npog ntsej muag, tshuab ultrasonic yas vuam tshuab, ultrasonic daim ntaub xaws thiab khoom siv embossing, thiab lwm yam. Cov lus nug thiab cov lus nug txog ultrasonic transducers: 1. Thaum lub ultrasonic vibrator tseem ntub, koj tuaj yeem siv megohmmeter los xyuas cov ntsaws txuas nrog tus transducer. 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. Cov. Yog tias qhov ntsuas hluav taws xob tiv thaiv tsis tau nce mus txog, qhov hloov pauv yog feem ntau noo tas. Koj tuaj yeem muab lub tshuab hloov pauv kom tag nrho (tsis suav lub ntsej muag yas-plhaub) rau hauv qhov cub thiab teeb nws ntawm 100 ℃ rau 3 teev lossis siv lub tshuab ziab plaub hau kom tshem tawm ya raws rau qhov tsis kam txog tam sim no. 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 tsis tshwm sim nyob rau hauv ib txwm muaj xwm txheej. 4. Lub stainless hlau vibrating nto yog perforated. Feem ntau, qhov vibrating nto tuaj yeem perforated tom qab 10 xyoo ntawm kev siv tag nrho-siv ntawm lub tshuab hloov tsheb.
