Indlela Yobuchwepheshe Bokuthola Uqhekeko Lwe-Yuantai Derun Square Tube Surface Crack
I-Yuantai DerunIshubhu LesikweleUbuchwepheshe Bokuthola Uqhekeko Olungaphezulu buhlanganisa kakhulu indlela yokungena, indlela ye-magnetic powder, kanye nendlela yokuthola ugesi we-eddy.
1. Indlela yokungena
Ukutholwa kwamaphutha angena ngaphakathi kuwukufaka uketshezi oluthile olunombala olunokungena kwamanzi ebusweni bepayipi lesikwele. Ngemva kokusula, uqhekeko lungabonakala ngoba kukhona uketshezi olusele emfantwini wepayipi lesikwele.
2. Indlela ye-magnetic powder
Le ndlela isebenzisa izinhlayiya ezincane zempuphu yamagnetic. Uma ingena ensimini yamagnetic evuzayo ebangelwa ukuqhekeka, izodonswa bese ishiywa. Njengoba insimu yamagnetic evuzayo ibanzi kunempuphu, impuphu yamagnetic eqongelelwe kulula ukuyibona ngamehlo enyama (njengoba kuboniswe esithombeni).
3. Indlela yokuthola yamanje ye-Eddy
Le ndlela yenziwa kusetshenziswa i-eddy current crack detector. Isimiso siwukuthi lapho i-detector ithinta i-crack ye-square tube, i-impedance ye-detector coil iyancishiswa ukuze kutholakale ushintsho ku-voltage, okungukuthi, inani elihambisanayo liboniswa ku-dial yensimbi noma kukhishwa umsindo we-alamu. Indlela ye-eddy current ingasetshenziswa futhi ukukala inani lokujula kwe-crack ye-square tube.
