2. The magnetic particle inspection equipment meets the process requirements
2.1 Utilizes fluorescent magnetic particle surface crack detection, with magnetization methods capable of revealing surface defects at each inspection point of the workpiece.
2.2 Properly and reasonably selecting process parameters, setting the current intensity, power-on time, and fluorescence intensity, etc., can ensure the required detection sensitivity; circumferential magnetization uses direct current method, and the current intensity should increase gradually from low to high. This machine employs a high-sensitivity contact resistance detection circuit, achieving non-burning of the workpiece's held area; the detection does not cause any damage to the workpiece surface. 2.3 This equipment is equipped with an automatic alarm device for non-powered workpieces. 2.4 It uses an external demagnetization method, with residual magnetic intensity less than 2 Gauss (0.2mT).
2.5 The machine can use water-based (or oil-based) magnetic suspension fluid, ensuring both effective flaw detection and compliance with safety and fire prevention requirements. 2.6 The flaw detector is equipped with a 250 demagnetization coil. 2.7 The machine can perform circumferential and longitudinal magnetization separately or simultaneously, and features a stepless adjustment of magnetization current.
