Ultrasonic Matotoru: whakahaere ngaahi tefito'i mo'oni, tohutohu, kaihanga, arotake

Ultrasonic inenga te matotoru, ko te tikanga kore-kino mō te whakatau i te whanui o te rauemi-iu kotahi. Ko reira nohopuku, pono, pūkenga, me, i roto i te rerekē ki te micrometer caliper ranei, e kore e rapua e te uru ki ngā taha e rua o te ahanoa. Ko te pūoko arumoni tuatahi, mā te whakamahi i te parau tumu o te pāorooro, puta i roto i te mutunga o 1940. Iti pūrere kawe, papaitia hoki te whānuitanga o ngā tono ngā, kua riro kitea i roto i te tau 1970. A auaha i roto i te hangarau microprocessor kua arahina ki te taumata hou o te pū, tapatahi, me te wāhinga.

pūrere Production whai wāhi i roto i te maha nui o kamupene pai-mohiotia. I roto ia ratou - te kamupene German Siemens, American Dakota Ultrasonics, Ingarangi Cygnus. I roto i Russia, whakaputaina nga whakaaro e kamupene pērā i SPF "AKS" NPK "kurupae", SPC "MaksProfit" me etahi atu.

He aha e taea ana te ruri?

I whakaritea tetahi tikanga rauemi hanga taea ana te ruri te whakamahi i ultrasound. pūoko Ultrasonic taea te whirihora ki konganuku, kirihou, composites, karaihe, okouku me te karaihe. Hoki inenga taea o kirihou extruded a whakataka atu i roto i te tukanga ahumahi - papa rite motuhake ranei coatings, me ngā tuhinga multilayer, wai me ngā tauira koiora. Ko tētahi atu mahi i reira e tika ana noa matotoru ultrasonic, - faaotiraa o te matotoru pereki, me ngā hanganga o te raima, uku me toka. Taua inenga e tata tonu kore-kino, me te rapu utu kahore whakairo disassembly ranei whare.

Materials kore e e tika ana mō te tikanga ine ultrasonic tika ki te tuku rawakore o ngaru nui-auau, ngā rakau, pepa, raima me ngā hua, pahuka.

Me pēhea te ki te whanganga?

taea pūngao Sound te hangaia i runga i te tūāwhiorangi auau whānui. Ko He tangi paraparau i roto i te whānui i te 20 ki te 20 kHz. Ko te teitei te auau, te teitei te reo ka mohio. Ko te pūngao o te auau teitei tua atu rongo tangata, ka karanga ultrasound. I roto i te nuinga o te wā, tirohanga ultrasonic kawea i roto i roto i te awhe auau i 500 kHz ki 20 MHz, ahakoa etahi taputapu motuhake tae 50 kHz 100 MHz ranei. Ahakoa o te auau, te pūngao pāorooro he wiri mīhini whakawhānui i roto i te reo tautuhi, pērā i te hau maitai ranei, i runga i ture taketake o ngaru ahupūngao.

Hoki inenga whakamahi i te mehua matotoru taiepa ultrasonic. Ko te parau tumu whakahaere o te pūrere ngā i roto i te tātai tangohia o te wā he pini tauwhiro o te uiuia iti (transducer) i roto i te ahanoa inenga, kitea tona mata i roto i te taiepa distal ranei. Mai ngaru oro whakaata atu rohe i waenganui i ngā rauemi Nä, kei te nuinga whakamana tenei inenga ki tetahi ringa, i roto i te "he pini / echo".

Ko te transducer Kei roto he huānga piezoelectric hiamo nei e te pini hiko poto ki te whakaputa motuhake ngaru ultrasonic. E tonoa ratou ki te rauemi i whanganga ano, a tika na reira noa fehangahangai koe te taiepa hoki atu he take whakahinga ranei. hoki te ngaru kitea ki te transducer i tahuri te wiri pūkaha ki pūngao hiko. I roto i te meka, gauges matotoru ultrasonic whakarongo hoki tavevo i te taha ki te ritenga atu. Tikanga, te wā wa i waenganui i te tono tangata, a te tohu kitea ko te torutoru noa millionths o te tuarua. Ko te pūrere tomo raraunga i runga i te tere tangi i roto i te rauemi i nei e taea e ka tātai i te reira i te matotoru mā te whakamahi i te hononga pāngarau ohie: d = V t / 2, ai:

• d - te matotoru o te wahi;
• V - tere o te oro;
• t - whanganga wa o te irava tangi.

He tawhā nui

He mea nui ki te mōhio e te tere o te oro i roto i te ahanoa i raro i ako ko ha konga mahu'inga 'o tenei tātai. rauemi rerekē tuku ngaru oro rerekē. Ka rite ki te tikanga, te totoka i runga taua mea, a roto i te ngohengohe - i raro. I tua atu, ka taea e rerekē te reira tino i te pāmahana. I te wa ano me nga wa katoa kia tukuoro te gauges matotoru ultrasonic mō te tere i roto i te rauemi i whanganga, i nei tika, tei runga i te tika o te pānuitanga.

ngaru Sound i roto i te MHz ngā roto whakamatauria kino te rangi, na ki te whakapai ake i te tuku tangi i waenganui i te kaituku me te tauira kei te whakanohoia he taka o te hononga inu. Tikanga, whakamahia te couplant nonireka, propylene glycol, wai, te hinu, me te rā. he nui iti anake o wai ki te whakaki i te āputa rangi tino kikokore.

aratau inenga

Manufacturers matotoru ultrasonic ine wā wā te pūngao haere i roto i te tauira whakamātautau i roto i ngā huarahi e toru:

1. Ko te wā i waenganui i te pini excitation, e mahia e te poipoi tangi, me te paoro e hoki tuatahi haunga te uara wāhikē iti, te roa wāhikē i roto i te taputapu, me te taura converter.
2. Ko te wā wā i waenganui i te tavevo hoki i te mata tauira, ka kitea e fepā'aki te tuatahi.
3. Ko te wā i waenganui i rua tei tavevo raro karapīpiti.

Te tohu i te tikanga puaki te momo o te transducer, me ngā whakaritenga tono motuhake. whakamahia te aratau tuatahi te ki te pūoko whakapā, me te e tūtohu hoki te nuinga o ngā tono. Ko te raina roa tuarua ko transducers hakari rumakina ranei tono ki te kōpapa me papa koropuku i roto i te wāhi kati, no te ine i te rauemi pokarekarenga ahanoa pāmahana teitei ranei.

e faaohipahia hoki te aratau toru o te aho roa pūoko rumaki ranei, me te nuinga o te wā whakarato tika tiketike, me te pai matotoru iti taumira. Tikanga whakamahia ina he kore pai o nga inenga kounga o te aratau tuatahi tuarua ranei. Heoi, he tika anake hoki rauemi e hua tavevo maha pokekore, rite ki te tikanga, ki te damping iti rite taua o konganuku pai-baked, karaihe, okouku te aratau muri.

E rua ngā momo o ngā pūrere

Kei te nuinga o te wā wehea Ultrasonic gauges matotoru ki e rua ngā momo: waikura, me te pū. Ko tētahi o nga tono tino nui ko te faaotiraa o te whanui o te taiepa maitai wäriu o putorino, oko, wāhanga hanganga me oko pēhanga e riro nei ki raro ki te waikura ā, me te kore ai e kitea i waho. mehua matotoru, te waikura ultrasonic me e hangaia mō tenei whakaaro. whakamahi rātou i ngā rautaki tukatuka tohu e kua papaitia kia rapunga o whanui taiepa wäriu iti i roto i ngā tauira pokepoke, me a waikuratia ki pūoko rua-huānga motuhake.

I roto i te tahi atu te wā, taunaki reira te whakamahi o te pū mea ki pūtahuri kotahi - mo konganuku, kirihou, kaka kōata, composites, rapa me ceramics. Na roto i te plurality o pūoko o ngā whakaaro pū, e taea whanganga ki te tika ± 0.025 mm teitei ranei o, i te mea teitei ake i te pōkai waikura.

Whakaröpütia Paerewa gauges matotoru ultrasonic i whakaaro, tohu o aunoatanga, tiaki i te rongo ki te taiao, ātete ki te ahotea mīhini, me whakarite ano ratou taupū matua.

momo o pūtahuri

• E whakamahia transducers Whakapā i roto i te whakapā tika ki te tauira whakamātautau. Inenga ki a ratou ngāwari, na e whakamahia ratou ake pinepine.
• Pūtahuri raina roa Kei roto kirihou, epoxy kiripaka rango ranei hei takawaenga i waenganui i te huānga hohe me te ahanoa whakamātautau. Ko te take matua mō rātou te whakamahi - Measurement o ngā kikokore, kei hea he mea nui ki te wehe i te ngātere excitation i te paoro raro. Ko te raina roa e taea te mahi rite te insulator wera, tiaki te pāmahana huānga pūoko tairongo i whakapā tika ki rauemi wera. Hoki, ka taea te hanga e te reira, te whakapai ake mau pu i roto i te piko koi papa koropuku ranei.
• transducers Submersible mō te tuku pūngao acoustic ki te huānga ruri te whakamahi i te pati i te wai tīwae ranei. E whakamahia ratou mo ine o neke taonga, no te matawai arotautanga o hononga ranei i te aroaro o koi radii, ngā awaawa takere ranei.
• Pūtahuri ki ngā āhuatanga e rua e whakamahia i roto i te shirinomerah ha'iriiri mō te whakatau i te whanui o ngā ki taratara, te mata waikuratia. Kei a ia ko whakawhitihia motuhake, me te fariiraa i huānga tāuta i te koki iti ki te raina roa ki te arotahi i te pūngao i te tawhiti tīpakohia i raro te mata o te tauira whanganga. Ahakoa kahore e rite tika rite tahi atu momo o pūoko taua inenga, ratou te tikanga whakarato mahi nui teitei.

Ultrasonic mehua Matotoru: ako

No te faaineine no te te transducer ine me hono ki te pūrere, tahuri ai ki runga ki, whakaturia te tere o te oro me te Whakatikaina. Ki te mahi i tenei, te tono he iti o te rauemi whakapā i runga i te paerewa whakatika, tāpiri i te pūoko ka taea aratau whakatika.

Matotoru Ultrasonic: arotake

Kaiwhakamahi pai aromatawai rahi kiato, noho pai o te whakamahi, tika, noho pai o te whakatika o ngā pūrere hou. Tohunga mōhio te ngaro o ētahi ki te whakaaro o tenei momo, ina te aromātai i te huru o waka, te kounga o te mahi o te Bodywork. hanga te pūrere e taea ki te whakatau mehemea te waka, ko te ki te repaint me ahakoa i whai wāhi ai i roto i te ati. Matotoru, hoki nei ki kahore couplant e hiahiatia ana, me te ahei kawe i whaiaro whakatika-, he tino rongonui.

Material me te whānui

Ultrasonic matotoru, te parau tumu o i tīpakohia i runga i te hanganga rānei, whanganga ngā, āhuahanga, te pāmahana, te whakaritenga tika me te tahi atu tikanga ka taea, i ētahi wā mahuinga noa.

momo rauemi, me te whānuitanga o inenga ko nga āhuatanga tino nui i roto i te pūrere whiriwhiri me te inverter. He maha matū, tae atu te nuinga o ngā konganuku, okouku me te karaihe, rawa tōtika whakamana te ultrasound te ka tukua hoki inenga i roto i te whānuitanga whanui. ka mimiti te nuinga kirihou pūngao, me te reira i te iti ngā matotoru mōrahi, engari i roto i te nuinga o ngā āhuatanga mahi e kore e inenga meinga raruraru. Rubber, kaka kōata me te tokomaha rauemi hiato mimiti nui kaha me te rapu utu atu foaki me farii e kua papaitia kia mahi i iarere iti.

whakatau matotoru te momo o te kaitahuri. whanganga ahanoa angiangi e i iarere tiketike, me te matotoru ranei damping - iti. Hoki ngā rauemi rawa kikokore whakamahia raina roa, ahakoa e iti ratou, me te transducers submersible i roto i inenga matotoru tika ki pokanoa i te paoro maha. I roto i te take o ngā whānui ranei tūemi arā, o te maha rauemi kia rapua e momo rerekē o pūoko.

Ko te curvature o te mata

Ki te hua i roto i te tōtika o te curvature o te mata whakapā i waenganui i te transducer me te ahanoa ki ana te ruri te te heke, Heoi ki te whakaiti i Me heke pūtoro o te curvature pūoko taumira. Ko te inenga o te radii iti rawa kia rapua e te whakamahi o ngā rārangi roa contactless transducers submersible ranei. taea hoki te whakamahi ratou mo inenga i roto i awaawa, kōwhao me era atu wahi ki te iti uru.

pāmahana

E te tikanga e hāngai ana ki te ahanoa transducers Whakapā i te pāmahana o te 50 ° C. Ka taea e rauemi wera atu tūkino i te pūoko tika ki te pānga o ngāwhā roha. I roto i ngā take pēnei i, kia whakamahi tonu koutou inverters ki aho roa, he, tiketike pāmahana rumaki ranei pūoko ki ngā āhuatanga e rua wera-ātete.

I roto i ētahi wā, ki te iti ahanoa parenga ia oro (kiato whakanuia e tere o te oro) hono te ki te rauemi ki te parenga ia oro tiketike. tauira Angamaheni - te kirihou, rapa me te karaihe paninga o te rino ranei te tahi atu konganuku, karaihe me te paninga polymeric. I roto i tenei take i te vanavanaiki i te rohe i waenganui i nga rauemi e rua e fazoinvertirovannym - kōaro ki te faatura ki te paoro i te rohe ki te rangi. taea te papaki i tēnei mā te huri noa nga tautuhinga o te pūrere, engari ki te mahi kahore te, katahi ka kia hē te pānui.

hapa
