针对传统接触式钢管漏磁探靴高速扫查时因剧烈摩擦而带来的磨损、发热等诸多问题,提出一种新型静压气浮探靴结构,其原理是,气流经过布置在气浮探靴上的节流孔后在钢管表面形成一层气膜,消除了探靴与钢管之间的直接摩擦,实现了非接触式跟踪。分析了气浮探靴静态特性与结构参数的关系,并针对直径为130mm的钢管设计了相应的漏磁探伤气浮探靴。%In order to solve the problems caused by high magnetic flux leakage testing speed for steel pipes,an aerostatic probe was proposed and the relationship among the static characteristics and structure parameters was analyzed. Finally,an aerostatic probe for steel pipe with diameter of 130mm was designed. The novel probe is especially suitable for high testing speed for that the friction between the probe and the steel pipe is avoided by the air--film.
