Soo noqnoqoshada sare ee 1khz ultrasonic ee aan caadiga ahayn ee 'ultrasonic'

Soo noqnoqoshada sare ee ugu habboon ee loo yaqaan 'Ultrasonic'

SideeSi loo qiimeeyo waxqabadka Transducter-ka ultrasonic?

Si loo qiimeeyo waxqabadka nidaamka gariirka ultrasonic, waxaa lagama maarmaan ah in la falanqeeyo laba waji: cabbirrada qaddarka iyo qalooca qalooca:

1) Cayayaanka:

Falanqaynta taxaddar leh ayaa loo isticmaali karaa in lagu qiimeeyo waxqabadka aaladaha kala duwan sida xaashiyaha dhoobada dhoobada ah ee piezoelectric, iyo dhammaan nidaamyada gariirka (dawladaha wareejinta oo lagu daray geesaha, wasaqda). Falanqaynta Qalabka aaladda ultrasonic oo leh falanqeeye aan daneyn lahayn, qiyaasaha ugu muhiimsan waa sida soo socota:

FS: Soo noqnoqoshada farsamada, tusaale ahaan inta jeer ee hawlgalka ee nidaamka gariirku, waa inuu ahaadaa mid u dhow qiimaha la filayo intii suurto gal ah qaabeynta waana in uu isbarbar dhigaa dhibicda hawlgalka korantada.

Mashiinka nadiifinta, waxa kor u kacaya isku-darka soo noqnoqda ee isdaba joogtu, ayaa ka sii fiican.

Loogu talagalay Wellows-ka caagga ah ama farsamada ultrasonic, haddii geeska ama qaabka caaryada aan macquul ahayn, soo noqnoqoshada soo-galka ah ee gariirka ayaa ka leexan doona barta hawlgalka.

R1: iska caabin firfircoon, iska caabbinta taxanaha taxanaha taxanaha taxanaha piezoelectric, ayaa ka yar kuwa ugu fiican isla shuruudaha taageerada. Nadiifinta ama gariirka alxanka, guud ahaan waa u dhexeeyaa5 ω iyo 20 ω. Haddii ay aad u ballaaran tahay, dhaqdhaqaaqa ama nidaamka gariirka ayaa yeelan doona dhibaatooyin, sida wareegga wareegga ama hufnaanta ugu hooseeya, iyo nolosha gaaban ee gariirka.

Qmyoher qm, waxa ugu fiican, maxaa yeelay sare ee QM, waxa ugu sareeya waxtarka vibrator; Laakiin QM waa inay isbarbar dhigtaa korantada, qiimaha QM waa mid aad u sarreeya oo saadka korantada uusan la mid aheyn.

Nadiifinta gariirka, qiimaha qaadka QM, ayaa ka fiican. Guud ahaan marka la hadlayo, QM-da nadaafadda nadiifinta waa inay ahaataa inta u dhexeysa 500 iyo 1000. Hadday aad u yar tahay, hufnaanta vibrator ayaa hooseysa. Hadday aad u sarreyso, korantada saadka lama isbarbardhigayo.

Loogu talagalay altrasonic alxanka ama mashiinka, qiimaha qm ee vibrator laftiisa ayaa guud ahaan ah qiyaastii 500 ~ ~ 1000, oo nidaamka oo dhanna waa 1500 ~ 3000. Haddii ay aad u hooseyso, hufnaanta gariirka ayaa hooseysa, laakiin aad uma sarreyso, maxaa yeelay sare ee QM, ayaa ah in korantada ay adagtahay, in korantada ay adagtahay in laga shaqeeyo qodobka soo noqnoqda, oo qalabkuna ma shaqeyn karo.

CT: Awoodda bilaashka ah, qiimaha cufan ee aaladda piezoelectric at 1 khz. Qiimahaan wuxuu la jaan qaadayaa qiimaha uu ku qiyaaso mitirka caadiga ah ee caadiga ah. Qiimahaani wuxuu kala goynayaa dafaca dhaqdhaqaaqa C1 si uu u helo Static Static Static Static Static C0, C0 = CT - C1. Markaad isticmaaleyso, isku dheelitirnaanta C0 ee lagu soo bandhigo.

Naqshadeynta wareegga mashiinka dharka lagu dhaqo ama mashiinka lagu maareeyo ee ultrasonic, isku dheelitirka saxda ah C0 wuxuu kordhin karaa qodobka awoodda ee korantada. Waxaa jira laba hab oo loo adeegsado isku-dheelitirka isbarbardhiga, isbarbardhigaya iyo caloosha taxanaha.

FP: Kahortaga - Soocelinta soo noqnoqoshada, soo noqnoqda ee la-socodka isbarbardhiga ee laanta Piezoelectric. Inta jeer ee la soo rogay, caqabadda zmax ee zmax of piezoelect-ka piezoelect waa kan ugu weyn. Haddii antik - ressirant Claicess zmax 'waa mid hoose, gariirku dhibaato ayuu qabaa.

2) garaafyada

Falanqaynta taxaddar leh waxay bixisaa shan nooc oo iskuduwaha ah oo isku dubbarida ah jaantusyo dabeecad ah, oo jaantusyada astaamaha logarithmicm waxay muhiimad muhiim ah ku leeyihiin ogaanshaha aaladaha piezoelectric. Waxqabadka gariirka ee gariirka piezoelectric gariir ama nidaam gariir ah ayaa si toos ah loogu xukumi karaa garaaf logarithmicmic ah, kaas oo ah mid caqli gal ah oo wax ku ool ah.

Xaaladaha caadiga ah, wareegga ogolaanshaha iyo qalooca xawaashka ayaa sida lagu muujiyey sawirka soo socda.

Fulin hawleed:

Goobaha aqbalaadda waa goob hal goobeed ah, oo garaafka logarithmicm wuxuu leeyahay labo yar oo qiimayaal ah iyo ugu badan:
