Ultrasonic pachiri: kurairirwa, diagram, nokurondedzerwa, vagadziri, ongororo

Kuongorora muviri pachishandiswa ultrasonic mafungu vakatanga kushandisa pakutanga rokupedzisira remakore. Rwokuyera mudziyo unonzi "ultrasonic hunonyadzisa." Pakarepo mushure kuwanikwa nzira vakadzungaira rakafara kukurumbira pakati mainjiniya uye vanhu kuitawo tsvakurudzo.

General ruzivo pamusoro muchina

Ultrassom chinopinda kuburikidza akaturikidzana zvinhu zvikukutu, uye vanogona kunyange kugadzira kuvapo kupfuura mutswe yaiva mukati menyika chinhu. The mudziyo unobvumidza kuziva kuremara kudzama 7-50 mm ane kururama ± 1 mm.

Ultrasonic pachiri michina vane yakasiyana siyana nehanya. Kwakadaro nechiidzo akatsunga diki kukura kuremara. The yezvinoreva kushandiswa vezvikwata rakafara chaizvo. Somuenzaniso, kugadzirwa simbi.

Nzwisisa inowanikwa mudziyo kunopa runziro uye yunifomu kushandisa midziyo. The mudziyo chinoratidza zvakarurama, kuita zvichiita kuti vawane mukuru-pamwero zvabuda uye kuona pane urema.

Nzvimbo kushandiswa chiridzwa

Chinanga kuonekwa kwakavakirwa Ultrasound angashandiswa chero chivakwa mashoko Detective kuvapo yakavigwa makatsemuka, pores, gang nezvimwe kuremara.

Rakajairika nzvimbo dzinosanganisira:

• Welds. Ndiro huru pokushandisa chikwata.
• Primary nesimbi zambuko matanda, nembariro, tsvimbo, sepombi workpieces.
• Infrastructure. Akakiya kubatana, njanji nokuti zvitima zviri simbi mamiriro.
• Petrochemical indasitiri. Kuongorora reservoirs mapaipi, mutoro-kubereka zvivako.
• Control mashandiro Makumbo miseve kudzidzisa motokari, ndege kumhara giya, kuturika Motors, kondo booms, nemotokari miseve, matangi nemidziyo zvaoma.
• kugadzirwa nharaunda. Rakauya nomoto vazvo, soldered majoini, zvigadzirwa zvakaitwa Kudzingwa, kudzora nezvokutsungirira zvinoumba zvinhu.
• Vachiongorora zvinhu zvikamu ndege, mhepo turbines, injini.

Application chinanga kunze

In indasitiri, ultrasonic pachiri michina zvave muna 50-ies. Ipapo akatevedzana chubhu mano rokutanga wakasikwa. Kubvira panguva iyoyo, hwakagadzira akazviunganidzira ruzivo rwakakura pane kushanda ultrasonic rokuongorora nzira.

Munyika dzokuEurope, rokuongorora atora achigona. Nezvokuvandudzika chimwe muzvitatu zvachose Vhoriyamu chigadzirwa kuongorora. Zvinonzi yakataurawo kuti, pasinei kushandisa michina webasa, nzira iyi anopiwa zvikuru akateerera.

Izvi zvakabatanidzwa yokuti yakawanda basa kuitwa panguva dzakadaro sezvo simba renyukireya miti, mapaipi vane zvinangwa zvakasiyana, simbi zvivako, motokari, uye vamwe. A pachena kuchiitwa zvivako izvi zvose zviri kusiyana kwavo, izvo zvinoomesa kushandiswa kushandisa michina.

Kushandiswa zviridzwa mudzimai indasitiri

Mudzimai indasitiri Ultrasound kudzora ane nzvimbo kutungamirira chinzvimbo. Izvi runoratidzwa nhamba nyanzvi vari mubasa basa rakafanana. Somuenzaniso, kubva muna 1994 kusvika 2000, maererano Ural advertising Center, zvakanzi kuedzwawo 1475 radiographers. 38% vavo vakava nyanzvi nyanzvi nokuda ultrasonic nzira. Zvakasiyana ndechokuti makura nhamba revashandi inobva kudzorwa nomoto vazvo.

Zvingakubatsira kushanda chikwata

ultrasonic basa chinanga detector pazvikanganiso pulsed nemwaranzi. Akaratidza ruzha zvinonyorwa uye kubvumira kuwana kuremara. Short redhiyo mafungu vanochinjwa ne B1-I3 piezoceramic mahwendefa. Ivo kubudikidza paiva couplant zvinhu anoparadzirwa muchimiro danda chete transverse mirayiridzo.

The akaratidza Ultrasound vibrations kuita pamusoro B1, B3 piezoceramic ndiro. EMF activation kunoitika, iyo inova kuchinja akasimba uye anopinda chinja pakakanganisika.

Main kuzvidzora nzira

Pane nzira dzakasiyana kudzora. Rakajairika, kuva mukuru kushanda, zvinosanganisira:

• ungira nzira;
• Nzira iri girazi-mumvuri kwakavakirwa;
• zvisina kugamuchirwa.

Chii iri pakakanganisika?

Chii Ultrasonic pakakanganisika? The zano anomiririrwa:

• Ropa jenareta ;
• zvichikurukura kuremara;
• Broadband amplifying mudziyo;
• zano nokuda nguva inogara amplitude;
• voltage regulator;
• unoponesa mudziyo.

Driving chikwata

Schematic chati mano akadai ultrasonic pachiri michina zvekupedzesa kunzwisisa.

Nheyo nokushanda mudziyo zvinogona nyore kunzwisiswa kana kuverenga nokungwarira waro chivako. How kushanda zano akadai ane ultrasonic pachiri detector, mirayiridzo achakuudza.

The chikuru Zvidhinha yazvino mharidzo mano ushande zvinotevera neBhaibheri:

• A jenareta zvinowanisa vachiridza pulses, zvinowanisa nemagetsi vibrations izvo fadza kuti ultrasonic mafungu kutendeuka mudziyo.
• Akaratidza Ultrasound anonongedzera kubva chakaremara inowanikwa chete (kana kubatanidzwa redunhu dhayagiramu mumwe yoga) wokutepfenyurisa. The anonongedzera zvinochinjwa kuva nemagetsi pulses inopiwa kune mazano ari gudzazwi.
• Kugadziridza kuhuwana munguva hunodzorwa nguva mutemo pamusoro nehanya wegadziriro (TCG).
• Yakawedzera kuti aida ukoshi mureza ndiwo mazano kune yemagetsi danda uye otomatiki aramu chakarurama kuremara (ASD).
• The synchronizing mudziyo chendangariro zvakarurama nokushanda kwenhengo dzose nguva kutevedzana kwezviitiko nodal nzvimbo mudziyo panguva imwe chete kutanga kurova kwemwoyo jenareta (kana nevamwe zvakafanorongwa kunonoka). It anotsigirwa ndichipfeka vakatanga timebase Erekitironi-danda chakarurama.
• Scan inoita kusiyanisa pakusvika nguva anonongedzera kufungisisa zvinhu izvo dziri panguva dzakasiyana kure wokutepfenyurisa. Synchronizer uyewo nebasa kuronga TCG mabhuroko uye SDA.
• Mano stuffed mudziyo kuyera amplitude uye pakasvika nguva kunooneka kufamba kweropa. Zano ravo usanganidzo unoitwa zvakasiyana siyana. Kuyera mudziyo kurongedza mashoko anonongedzera vakagamuchira kubva gudzazwi pamwe kupararira nguva synchronizing mudziyo, uye outputs kuti digitaalinen zviratidzi Erekitironi-danda chakarurama kana yoga purangazve.

mudziyo Configuration

Chakaita ultrasonic pachiri detector rinotanga kugadzwa mudanga chizvarwa ari voltage kutendeuka mudziyo. Panguva iyoyo vakatakura akabudisa Kusarudzwa pakati resistor R39. Ipapo vakawana achida kudzokorora kakawanda (120-150 cpm / s), mumwe kusarudzwa anoiswa resistor R2.

amplitude indekisi pamusoro 70-80 pulses / chik runowanikwa kusarudzwa dynistor V1. Zvadaro vachiwirirana capacitors C22 uye C26, izvo anochinja kuisa muganhu pamwe muhombe injini resistors R30 uye R35 uye monostable multivibrator kunonoka nguva pulses (10-25 microseconds) uye kudzora zvikamu (7-45 microseconds).

vachiongorora mano

Verification of ultrasonic pachiri detector yakaitwa nenzira dzakasiyana-siyana:

• Wokutanga iri kwebasa rinofanira rinokosha redunhu dhayagiramu simulating mudziyo emitting bvunzo chiratidzo. The Zvakashatira mudziyo uyu dzevamhan'ari mudziyo hushande uye nekusagona kutarisa acoustics chinhu chinogumbura.
• Anozivikanwa uye nzira inoitwa nokuda simulation pamusoro ungira anonongedzera, avo nemwaranzi ari configuration muenzaniso. Zvadaro, pashure kugamuchirwa zviri kuongororwa chinanga electroacoustic turakiti chete. Kune zvaisanganisira emitting uye kugamuchira zvikamu yemagetsi mudziyo chikwata kuti zvienderane vachiongorora uye nemagetsi netambo unobva vachiongorora kuti chikwata. The Zvakashatira nemuedzo wakadaro ndiye kushandiswa chete nzira yokuti chinanga rine kuramba chinozunguzirwa ultrasonic nemafungu uye kubudiswa anonongedzera kunobva kurutivi Doppler maturo. Izvi mhinduro hakubvumirwi kuti kudzorwa vakawanda ano yokutevedzera mano anoparadzirwa munyika yose.
• Verification rinoitwa ultrasonic pachiri detector, uye nedzimwe nzira. Zvinonzi papfungwa yokuti acoustic hadzisisina akatasva nokushandisa imwe marongero mvura kuonana mharidzo pasi muenzaniso. Izvi zvinopa acoustic coupling pakati mharidzo nechigumbuso uye acoustics. The acoustic chikwata inongorira ultrasonic mafungu mharidzo. Zvinoratidzwa kubva yomukati reflector ungira anonongedzera tinogamuchirwa uye yakakura mune mharidzo. Zviri kwekanguva selection, izvo zvokudya kuti chakarurama mano. On kunaka chikwata haanzverwi padanho aramu zviratidzo. Kuti dzika nzira iyi inoshanda resimbi mudziyo kana munhu makemikari magirazi pamwe reflectors dzinongoda mukati. aishandiswa zvose pakakanganisika kutungamirira vagadziri pose Similar namano.
