Ⅰ.Chii chinonzi bvunzo dzisiri dzekuparadza?
Kazhinji, kuyedza kusingaparadze kunoshandisa hunhu hwekurira, mwenje, magetsi uye magineti kuona nzvimbo, saizi, huwandu, hunhu uye rumwe ruzivo rwakabatana rwepedyo-pamusoro kana hurema hwemukati pamusoro pechinhu chacho pasina kukuvadza zvinhu zvacho. Kuedza kusingaparadzi kunovavarira kuona hunyanzvi hwezvinhu, kusanganisira kuti vanokwanisa here kana kuti vane husina kukanganisa hupenyu hwesevhisi, hunosanganisira kusakanganisa hupenyu hwesevhisi. ultrasonic test, electromagnetic test, uye magnetic particle test, pakati payo Ultrasonic Test ndiyo imwe yenzira dzinonyanya kushandiswa.
Ⅱ.Nzira shanu dzakajairika dzisiri dzekuparadza dzekuyedza:
Ultrasonic Bvunzo inzira inoshandisa hunhu hwemasaisai e ultrasonic kuparadzira uye kuratidza mumidziyo kuona hurema hwemukati kana zvinhu zvekunze mumidziyo. Inogona kuona kukanganisa kwakasiyana-siyana, zvakadai sekuputika, pores, inclusions, looseness, etc. Ultrasonic kukanganisa kukanganisa kwakakodzera zvinhu zvakasiyana-siyana, uye inogonawo kuona kuwanda kwezvinhu, zvakadai sesimbi, kwete-metals, composite zvinhu, etc. Ndiyo imwe yenzira dzinowanzoshandiswa mukuedzwa kusina kuparadza.
Sei mahwendefa esimbi akakora, mapaipi akakomberedzwa nemadziro uye mahombe-diameter ekutenderera mabhawa akakodzera bvunzo dzeUT?
① Kana ukobvu hwezvinhu hwakakura, mukana wekukanganisa kwemukati senge pores uye makatsemuka achawedzera zvinoenderana.
②Forgings inogadzirwa kuburikidza nekugadzira nzira, iyo inogona kukonzera kuremara senge pores, inclusions, uye kuputika mukati mechinhu.
③Mapombi akatetepa-akakomberedzwa uye akakura-dhayamita akatenderera tsvimbo anowanzo shandiswa mukuda mainjiniya zvimiro kana mamiriro anotakura kushushikana kwakanyanya. UT bvunzo inogona kupinda mukati memukati mezvinhu uye kuwana zvinogona kukanganisa mukati, senge makatsemuka, inclusions, nezvimwe, izvo zvakakosha pakuona kutendeseka uye kuchengetedzeka kwechimiro.
2.PENETRANT TEST tsanangudzo
Mamiriro anoshanda eUT Muedzo uye PT Muedzo
UT bvunzo yakakodzera kuona kukanganisa kwemukati kwezvinhu, senge pores, inclusions, kuputika, etc. UT bvunzo inogona kupinda mukati mehukobvu hwezvinhu uye kuona hurema mukati mechinhu nekuburitsa masaisai e ultrasonic uye kugamuchira zviratidzo zvinoratidzwa.
PT bvunzo inokodzera kuona kuremara kwepamusoro pamusoro pezvinhu, senge pores, inclusions, kuputika, etc. Kuongororwa kwePT kunovimba nekupinda kwemvura mukati mepakatsemuka kana kuremara uye inoshandisa mugadziri weruvara kuratidza nzvimbo uye chimiro chehurema.
UT bvunzo uye PT bvunzo dzine zvadzo zvakanakira uye zvazvakaipira mumashandisirwo anoshanda. Sarudza nzira yekuyedza inoenderana neyakasiyana bvunzo zvinodiwa uye hunhu hwezvinhu kuti uwane zvirinani mhedzisiro yekuyedza.
3.Eddy Current Test
(1) Nhanganyaya kuET Muedzo
ET Muedzo inoshandisa musimboti we electromagnetic induction kuunza inochinjika ikozvino-inotakura bvunzo coil padyo neconductor workpiece kugadzira eddy currents. Zvichienderana nekuchinja kwe eddy currents, zvivakwa uye chimiro cheiyo workpiece inogona kuverengerwa.
(2) Zvakanakira zveET Muedzo
ET Muedzo haudi kutarisana neworkpiece kana yepakati, iyo yekuona kukurumidza inokurumidza, uye inogona kuyedza zvisiri-metallic zvinhu zvinogona kukonzera eddy currents, senge graphite.
(3) Kuganhurirwa kweET Muedzo
Inogona chete kuona kuremara kwepamusoro kwezvinhu conductive. Paunenge uchishandisa kuburikidza-mhando coil yeET, hazvigoneke kuona chaiyo nzvimbo yekukanganisa pane denderedzwa.
(4) Mari uye mabhenefiti
ET Test ine midziyo iri nyore uye iri nyore kushanda. Izvo hazvidi kudzidziswa kwakaoma uye zvinogona kukurumidza kuita chaiyo-nguva yekuyedza pane saiti.
Nheyo yekutanga yePT bvunzo: mushure mechikamu chechikamu chakaputirwa nedhayi yefluorescent kana dhayi ine ruvara, iyo inopinda mukati inogona kupinda mukati meiyo yekuvhura kwepamusoro kukanganisa pasi penguva yecapillary action; mushure mekubvisa yakawandisa inopinda pamusoro pechikamu, chikamu chinogona kunge Shandisa mugadziri kumusoro. Saizvozvo, pasi pechiito che capillary, mugadziri achakwezva iyo inopinda inochengeterwa mukuremara, uye iyo inopinda inopinda ichidzokera zvakare mukuvandudza. Pasi peimwe mwenje sosi (ultraviolet mwenje kana chena mwenje), mitsetse yeinopinda pakaremara icharatidzwa. , (yellow-green fluorescence kana tsvuku tsvuku), nokudaro kuona morphology uye kuparadzirwa kwezvikanganiso.
4.Magnetic Particle Testing
Magnetic Particle Testing" inowanzoshandiswa isingaparadzi nzira yekuongorora yekuona pamusoro uye pedyo-pamusoro-soro pakakanganisika mune conductive zvinhu, kunyanya pakuona makatsemuka. Inobva pane yakasarudzika mhinduro yemagineti kune magineti minda, inobvumira kuona kunoshanda kwekukanganisa kwepasi pevhu.
5.RADIOGRAPHIC TEST
(1) Nhanganyaya yeRT Test
X-rays mafungu emagetsi emagetsi ane frequency yakakwira zvakanyanya, yakanyanya kupfupi wavelength, uye yakakwirira simba. Vanogona kupinda mukati mezvinhu zvisingagoni kupinzwa nechiedza chinooneka, uye kuita maitiro akaoma nezvinhu panguva yekupinda.
(2) Zvakanakira zveRT Muedzo
RT Bvunzo inogona kushandiswa kuona kukanganisa kwemukati kwezvinhu, senge pores, kusanganisirwa kwakatsemuka, nezvimwewo, uye inogona zvakare kushandiswa kuongorora kutendeseka kwechimiro uye yemukati mhando yezvinhu.
(3) Nheyo yeRT Test
RT Muedzo unoona hurema mukati mechinhu nekuburitsa maX-ray uye kugamuchira masaini anoratidzwa. Kune zvinhu zvakakora, UT bvunzo inzira inoshanda.
(4) Kuganhurirwa kweRT Muedzo
RT Test ine zvimwe zvinogumira. Nekuda kwehurefu hwayo uye hunhu hwesimba, X-rays haigone kupinda mune zvimwe zvinhu, senge lead, iron, Stainless simbi, nezvimwe.
