Zolakwika za pamwamba pamachubu ozungulirazidzachepetsa kwambiri mawonekedwe ndi ubwino wa zinthu. Momwe mungazindikire zolakwika pamwamba pamachubu ozunguliraKenako, tifotokoza njira yodziwira zolakwika pamwamba pa khungu la m'munsichubu cha sikweyamwatsatanetsatane
1, Kuyesa kwa Eddy current.
Kuyesa kwa Eddy current kumaphatikizapo kuyesa kwamakono kwa eddy current, kuyesa kwa far-field eddy current, kuyesa kwa multi frequency eddy current ndi kuyesa kwa pulse eddy current. Pogwiritsa ntchito masensa a eddy current kuti mumve chitsulo, mitundu yosiyanasiyana ya zizindikiro idzapangidwa malinga ndi mitundu ndi mawonekedwe a zolakwika pamwamba pa machubu a sikweya. Ili ndi ubwino wolondola kwambiri, kuzindikira kwambiri komanso liwiro lozindikira mwachangu. Imatha kuzindikira pamwamba ndi pansi pa chitoliro choyesedwa popanda kukhudzidwa ndi zonyansa monga mafuta pamwamba pa chitoliro choyesedwa. Zoyipa zake ndi zakuti ndikosavuta kuweruza kapangidwe kopanda chilema ngati cholakwika, kuchuluka kwa kuzindikira kolakwika ndi kwakukulu, ndipo kuzindikira kosadziwika sikophweka kusintha.
2. Kuyesa kwa Ultrasonic
Pamene mafunde a ultrasound alowa mu chinthucho ndikukakumana ndi vuto, gawo la mafunde a acoustic lidzawonekera. Chotumizira mafunde chimatha kusanthula mafunde owonetsedwa ndikupeza zolakwika mwanjira yosazolowereka komanso molondola. Kuyesa kwa ultrasound nthawi zambiri kumagwiritsidwa ntchito poyesa zomangira. Kuzindikira kumakhala kokwera, koma payipi yokhala ndi mawonekedwe ovuta sikophweka kuzindikira. Pakufunika kuti pamwamba pa chubu chowunikiracho pakhale kusalala kwina, ndipo kusiyana pakati pa probe ndi pamwamba powunikira kudzazidwa ndi cholumikizira.
3. Kuyesa tinthu ta maginito
Mfundo ya njira ya tinthu ta maginito ndiyo kuzindikira mphamvu ya maginito mu zinthu za chubu cha sikweya. Malinga ndi momwe mphamvu ya maginito yotayikira ndi tinthu ta maginito zimagwirira ntchito, pakakhala kusagwirizana kapena zolakwika pamwamba kapena pafupi ndi pamwamba, mizere ya mphamvu ya maginito idzasokonekera pamalopo pa kusagwirizana kapena zolakwika, ndipo mitengo ya maginito idzapangidwa. Ubwino wake ndi ndalama zochepa zogulira zida, kudalirika kwambiri komanso kuwonetsa bwino. Zoyipa zake ndi mtengo wokwera wogwirira ntchito, kugawa zolakwika molakwika komanso liwiro lochepa lozindikira.
4. Kupeza infrared
Mphamvu yotulutsira mpweya imapangidwa pamwamba pa chubu cha sikweya kudzera mu coil yotulutsira mpweya ya high-frequency. Mphamvu yotulutsira mpweya imapangitsa kuti malo olakwikawo agwiritse ntchito mphamvu zamagetsi zambiri, zomwe zimapangitsa kuti kutentha kwa m'deralo kukwere. Gwiritsani ntchito infrared kuti muzindikire kutentha kwa m'deralo ndikudziwa kuya kwa vuto. Kuzindikira kwa infrared nthawi zambiri kumagwiritsidwa ntchito pozindikira zolakwika pamwamba, koma osati pozindikira zolakwika pamwamba.
5. Mayeso otayira madzi a maginito
Njira yoyesera kutuluka kwa maginito ya machubu ozungulira ndi yofanana kwambiri ndi njira yoyesera tinthu ta maginito, ndipo kuchuluka kwake, kukhudzidwa kwake, ndi kudalirika kwake ndizolimba kuposa njira yoyesera tinthu ta maginito.
