Principle of Eddy Current Testing: Eddy current testing uses the principle of electromagnetic induction to excite the probe coil with sinusoidal current. When the probe is close to the metal surface, the alternating magnetic field around the coil generates induced current on the metal surface. For flat metal, the flow of the induced current is a concentric circle of coils, shaped like a vortex, called an eddy current. The eddy also generates a magnetic field of the same frequency, in the opposite direction of the coil's magnetic field. The loss resistance of the eddy current channel and the anti-magnetic flux generated by the eddy current are reflected back to the probe coil, changing the current magnitude and phase of the coil, that is, changing the impedance of the coil. Therefore, when the probe moves on the metal surface and encounters defects or changes in material and size, the reaction of eddy current magnetic field to the coil is different, resulting in changes in coil impedance. By measuring such changes with eddy current testing instruments, the metal surface can be identified with defects or other physical property changes. There are many factors that affect the eddy current field, such as the degree of coupling between the probe coil and the material under test, the shape and size of the material, electrical conductivity, magnetic permeability, and defects. Therefore, the problems of flaw detection, thickness measurement and sorting of metal materials can be solved by using eddy current principle


Technical parameters: flaw detection sensitivity: from the workpiece surface to the metal extending depth ≥ 0.05mm, length ≥2 mm crack, defect; When the thickness of the metal between the top edge of the crack and the surface of the workpiece is ≤ 0.2mm, the crack with a depth of ≥0.20mm and a length of ≥ 1mm can be detected.

全自動搖臂軸承渦流探傷機

超聲波頻率高、平行線性強、在固態中廣為流傳、并且碰到二種區別物質產生的頁面時便于反射,因此 超聲波探傷儀的問世為全自動渦流探傷機設備增加了許多光鮮亮麗顏色。一般用超聲波探傷儀攝像頭與待探產品工件容貌精湛的戰斗,攝像頭則可合理地為產品工件發送超音波,并能消化吸收(缺點)頁面反射來的超音波,另外轉化成電子信號,再傳送給儀器設備舉辦超聲波探傷儀數據處理方法。憑證超音波在物質中廣為流傳的速度(常稱波速)和廣為流傳的時間,就可了解缺點的部位。

探傷儀中對缺點的表現要點有多種多樣,超聲波探傷儀合理磁粉表現的,也是有未消磁粉表現的。用磁粉表現的稱之為磁粉探傷檢測,因它表現形象化、控制樸素、大家善于利用,故它是最常見的要點之一。未消磁粉表現的,風俗習慣上稱之為漏磁探傷檢測,它常憑借覺得電磁線圈、磁敏管、霍爾傳感器等來反映缺點,探傷儀它比磁粉探傷檢測更環境衛生,但比不上前面一種形象化。模塊鋼軌渦流探傷儀配置的智能化超聲波探傷儀在儲存原效仿超聲波探傷儀根天特性的功底上,利用籌算機管理體系作用,對傷損雷達回波舉辦智能化應急處置懲罰,具備數據信息記述作用,能操縱探傷儀實行速度和記述各種各樣探傷檢測數據信息。
