Cov qauv thiab cov ntsiab cai ntawm ultrasonic vuam tshuab
Lub tshuab nqus hlau ultrasonic feem ntau yog tsim los ntawm cov ntu hauv qab no: lub tshuab hluav taws xob, lub tshuab pneumatic, feem tswj qhov kev pab cuam, thiab ntu kev hloov pauv. Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob yog hloov 50Hz hluav taws xob txuas nrog hluav taws xob hluav taws xob mus rau hauv high-zaus (piv txwv li 20KHz) high-voltage hluav taws xob xob; cov haujlwm tseem ceeb ntawm pneumatic feem yog ua tiav cov kev ua haujlwm siab kom ua haujlwm raws li lub siab thiab nias thaum lub sijhawm ua haujlwm; tswj lub txheej txheem Ib feem tswj cov txheej txheem ua haujlwm ntawm tag nrho lub tshuab kom ua tiav cov txiaj ntsig ua kom zoo; ib feem ntawm qhov hloov pauv hloov lub tshuab hluav taws xob high-voltage hluav taws xob uas tsim los ntawm lub tshuab hluav taws xob mus rau kev siv tshuab kev co, uas yog kis thiab ua kom loj dua kom mus txog qhov kev lag luam.
Feem ntau muaj ob hom kev tsim hluav taws xob uas tau siv dav hauv Suav: Ib qho yog tus choj hluav taws xob amplifier Circuit Court siv los ntawm Tsoomfwv Meskas BRANSON lub tuam txhab, kev tiv thaiv Circuit Court siv theem kev tiv thaiv, thiab qhov ua haujlwm khiav haujlwm feem ntau yog 20KHz. Nws kom zoo dua yog qhov hluav taws xob hloov dua siab zog. Qhov tsis zoo yog tias qhov ntau zaus hloov kho inductance kev hloov kho qhov ntau yog nqaim thiab qhov zaus mus xyuas qhov ua haujlwm tsis zoo; lwm qhov kev tsis txaus ntseeg yog tias lub zog tsis tuaj yeem ua rau loj, qhov siab tshaj plaws yog txog 3KW; lwm qhov yog Taiwanese tshuab, uas yog hom Siv cov chav kawm B lub zog ua kom muaj zog, tiv thaiv kev tiv thaiv, choj tawm tswv yim. Qhov kom zoo dua yog tias lub zog tuaj yeem ua qhov loj dua (xws li 4.2KW), qhov khiav ceev mus txog qhov ua tau zoo, thiab qhov ua haujlwm zaus ntawm 15KHz feem ntau siv nyob rau hauv qhov xwm txheej ntawm lub zog loj. Qhov tsis zoo yog tias qhov hluav taws xob hloov hluav taws xob ua haujlwm tsawg, thiab qhov ua haujlwm zaus ntawm 15KHz yog hnov tau kom tib neeg pob ntseg, xav txog lub suab nrov dua; ntxiv rau, muaj cov tshuab siv cov tshuab hluav taws xob ntau zaus nrhiav tau hauv Switzerland, Lub Tebchaws Yelemees, thiab Nyij Pooj. Vim tias nws cov nqi siab, nws tsis yog ib qho tshwm sim hauv Suav teb.
Lub tshuab hloov ua ntu muaj peb ntu: transducer (TRANSDUCER), amplifier (tseem hu ua ncej theem nrab, tshuab raj, BOOSTER), lub taub hau vuam (tseem hu ua vuam tuag, HORN lossis SONTRODE).
Transducer (TRANSDUCER): Lub luag haujlwm ntawm kev hloov pauv yog hloov mus rau hluav taws xob cov hluav taws xob mus rau kev siv lub tshuab co. Muaj ob lub cev qhov cuam tshuam uas tuaj yeem siv los hloov hluav taws xob cov hluav taws xob rau hauv cov teeb liab kev co tshuab. A: Cov nyhuv Magnetostrictive. Magnetostrictive effect feem ntau siv hauv kev siv ultrasonic thaum ntxov. Nws cov tau zoo yog tias nws muaj qhov muaj peev txheej loj lub zog; nws qhov tsis zoo yog tias nws tsis tshua muaj siab hauv kev hloov ua tau zoo, nyuaj rau kev tsim khoom, thiab nyuaj rau pawg ntau lawm. B: Qhov rov qab hloov ntawm cov nyhuv piezoelectric. Piezoelectric ceramic transducers muaj qhov zoo ntawm kev hloov pauv ua haujlwm siab thiab kev tsim khoom loj. Qhov tsis zoo yog tias lub peev xwm tsim tawm yog qhov me me. Cov tshuab ultrasonic uas twb muaj lawm feem ntau siv cov piezoelectric ceramic transducers. Lub piezoelectric ceramic transducer yog tsim los ntawm sandwiching lub piezoelectric ceramic nruab nrab ntawm ob lub hlau pem hauv ntej thiab nram qab ntsaws cov khoom thaiv thiab txuas nruj ntawm lub hau ntswj. Qhov tso zis amplitude ntawm ib qho kev hloov pauv ib txwm yog li 10 μm.
OS BOOSTER: Lub tshuab raj kub nws tus kheej yog lub thawv tooj hlau. Los ntawm kev tsim qauv ntawm cov duab, qhov loj me uas xa los ntawm lub tshuab hloov pauv tuaj yeem ua kom tau lub zog kom ua tiav lub zog tsim nyog rau kev ua cov yas, uas yog sib npaug nrog cov cua kub, xws li kev ua kom dav li tsawg tau rau peb cov nquag siv ABS thiab AS plastics yog txog 20μm; cov ua kom ntau yuav tsum tau nylon thiab polypropylene yog li 50μm.
OR HORN: Kev ua haujlwm ntawm lub taub hau vuam yog ua cov khoom yas tshwj xeeb thiab ua tau raws li qhov xav tau ntawm cov duab thiab ua cov txheej txheem ntawm cov yas ntu.
Cov transducers, tshuab raj, thiab taub hau vuam yog txhua tus tsim los ua ib nrab nthwv dej ntawm cov ua haujlwm ultrasonic zaus, yog li lawv qhov loj thiab cov duab yuav tsum tau tsim tshwj xeeb; ib qho kev hloov kho twg yuav ua rau muaj qhov hloov pauv ntawm zaus thiab kev hloov pauv, yog li nws tsim nyog Kev cob qha kev tsim khoom. Ua raws li cov khoom siv, qhov loj yuav txawv. Cov ntaub ntawv tsim nyog rau ultrasonic transducers, tshuab raj thiab lub taub hau vuam yog: titanium alloy, aluminium alloy, alloy hlau, thiab lwm yam Vim hais tias ultrasonic vuag co tas li ntawm qhov siab ntawm 20KHz, qhov uas yuav tsum muaj rau cov khoom siv yog qhov siab heev, uas tsis yog cov khoom zoo li cas tuaj yeem tiv thaiv.
