Abstract

The embodiment of the invention provides a magnetic suspension volume concentration detection method and detection system and a magnetic powder flaw detection system. According to the specific implementation scheme, the detection system comprises a magnetic suspension loading container, a magnetic device, a control device and a detection device; the control device is detachably connected with the magnetic suspension loading container; the magnetic device is positioned below the bottom of the magnetic suspension loading container; the control device is used for controlling the magnetic suspension loading container to obtain a to-be-detected magnetic suspension with a preset volume from the magnetic particle flaw detector; the magnetic suspension loading container is used for loading the to-be-detected magnetic suspension; the magnetic device is used for adsorbing magnetic powder in the to-be-detected magnetic suspension to the bottom of the magnetic suspension loading container within preset time; and the detection device is used for acquiring volume data of the magnetic powder in the magnetic suspension loading container and volume data of the to-be-detected magnetic suspension, and calculating the volume concentration of the magnetic suspension. The detection system provided by the embodiment of the invention improves the efficiency of detecting the volume concentration of the magnetic suspension.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of flaw detection of workpieces, and in particular to a method for detecting the volume concentration of a magnetic suspension liquid, a detection system, and a magnetic particle flaw detection system. Background technique [0002] When performing wet magnetic particle flaw detection, small particles of magnetic powder are mixed into the carrier liquid, and the carrier liquid is used as the carrier to evenly spray the magnetic powder onto the surface of the workpiece. If there is a defect in the magnetized workpiece, the defect will appear. Leakage magnetic field, the leakage magnetic field will attract the magnetic powder in the carrier liquid distributed around the defect to gather and form magnetic marks to find the defect. This kind of suspension formed by mixing magnetic powder and carrier liquid in a certain proportion is called magnetic suspension, and the amount of magnetic ...
