Penetration bvunzo (PT) zvakare imhando yekusaparadza bvunzo. Nheyo yayo yakakosha ndeye kushandisa iyo yakanaka permeability uye capillary chiito chemavara mapenereta kana fluorescent penetranti kutetepa maburi. Mushure mekupinda, kubviswa, uye kurapwa kwekufungidzira, kuremara kwepamusoro kunowedzera uye kuratidzwa. , kuitira kutonga chirema rudzi, nzvimbo uye saizi. Penetrant test ndeye kushandisa yekutarisa yekuona kana girazi rekukudza kuona discontinuities mumazaru ari pamusoro pe.simbi yekukanda zvigadzirwa. Nekudaro, kuyedzwa kwekupinda hakugone kunyatso ratidza hunhu, chimiro, saizi uye kudzika kwekuremara kunoramba kuripo.
Penetrant ndiyo inonyanya kukosha mukuongorora kwemukati, uye hunhu hwayo hunokanganisa zvakananga kunzwa kwekuongorora. Mapeneti anofanirwa kuve neakanakisa ekunyorova zvivakwa kuti ave nechokwadi chekupinda zvivakwa. Kana iyo inopinda inosanganiswa nemavara ane mavara kana fluorescent dyes, inobatsira pakukura kwekuremara. Kuona kukanganisa kweruvara kunoshandisa dhayi dzine ruvara sechinhu chinoratidza ruvara kune vanopinda, nepo fluorescent kutadza kuona kunoshandisa fluorescent poda sechinhu chinovhenekera kune vanopinda. Shading nzira dzinogona kushanda mukati memukati kana kunze nharaunda. Fluorescent penetrant inspection inoshandisa fluorescence inoburitswa pasi pe ultraviolet mwenje inoburitswa nechiedza chitema kuratidza hurema hwepamusoro, saka inofanirwa kuitwa mukamuri ine rima.
Castings inoda kuongororwa kwemukati inofanira kucheneswa isati yaongororwa, uye kushata kwepamusoro kunofanirwa kusangana nezvinodiwa zvemhando yepamusoro. Ngura, chiyero uye pendi, girisi, unyoro, nezvimwewo pamusoro pekukanda kunofanira kubviswa. Mushure mokunge kuongorora kwemukati kwapera, nzvimbo yekukanda inofanira kubviswa kubva kune inopinda uye mugadziri, yakaomeswa uye, kana zvichidiwa, yakachengetedzwa kubva pakuora.
Hunhu hwePenetrant Testing uye Chikamu Chayo cheKushandisa:
1. Nzira uye midziyo iri nyore uye inogadziriswa.
2. Chimiro chekukanda hachina kuganhurirwa, uye hutsinye hwepamusoro hwenzvimbo yakaongororwa hunoenderana nehuwandu hwemhando yekukanda.
3. Kushanda kuri nyore, kunzwisiswa kwakanyanya, uye kwete kuganhurirwa nezvinhu zvenyama.
4. Kukandira chete kukanganisa pamusoro kana padyo nepamusoro pekukanda kunogona kuonekwa.
