Description

technical field [0001] The invention relates to the technical field of magnetic suspension configuration, in particular to an automatic configuration device for magnetic suspension. Background technique [0002] Non-destructive testing is the main method to judge casting defects, including MT, UT, RT, PT, etc. Magnetic particle testing (MT) is a non-destructive testing method that detects defects on or near the surface of ferromagnetic materials by accumulating magnetic particles in the leakage field near the defect. The flaw detection method is to magnetize the workpiece made of magnetic materials such as iron and steel, and use the magnetic leakage energy of the defective part to absorb the magnetic powder, and display the surface defects and near-surface defects of the detected object according to the distribution of the magnetic powder. The flaw detection method is characterized by simplicity and intuitive display. In order to ensure the reliability of the magnetic par...

Problems solved by technology

At present, in the magnetic particle inspection, due to the constraints of manual configuration, concentration of magnetic suspension, uneven uniformity, poor suspension effect, and low efficiency, the quality of the prepared magnetic suspension is uneven. For large castings that require overall magnetization , manual operation brings exponentially increased workload, which brings certain troubles to magnetic particle testing

[0003] At present, there are related equipment to realize the configuration of the magnetic particle flaw detection magnetic suspension, but these methods and equipment only realize the simple operation of the magnetic suspension configuration process, and fail to analyze the stirring time, water injection volume, magnetic suspension concentration, ejection volume and residual liquid. Considering the key automation links such as quantity, so there is no automatic configuration equipment for industrial magnetic particle inspection and magnetic suspension.
