  一、電火花檢測儀的工作原理與技術(shù)特點
 
  1. ??核心工作原理??
 
  電火花檢測儀基于??高壓脈沖放電??原理工作:當(dāng)探頭(電極)靠近導(dǎo)電性被測材料表面時,兩者間形成強(qiáng)電場。若材料表面存在缺陷(如裂紋、孔隙),該處電場強(qiáng)度劇增,導(dǎo)致空氣擊穿并產(chǎn)生可見電火花(同時伴隨聲光信號)。通過分析放電強(qiáng)度、頻率及位置,可定位缺陷的尺寸與深度。
 
  ??技術(shù)優(yōu)勢??:
 
  ??高靈敏度??:可檢測微米級表面開口缺陷(如寬度≥0.01mm的裂紋);
 
  ??非接觸式??:避免機(jī)械接觸對精密工件的損傷(如拋光鏡面、超薄結(jié)構(gòu));
 
  ??快速高效??:檢測速度可達(dá)0.5~2m²/min,適合批量生產(chǎn)線的在線檢測。
