XJD-A Rotatory Magnetic Field Pit-Shape Multi-function Detector Applicable scope Suitable for all kinds of complicated shape of ferromagnetic workpiece magnetic particle inspection， Such as railway locomotive vehicle couplers , coupler knuckle , axle box body, installation, gear, fork joint and so on complex shape of magnetic particle inspection of casting and forging parts Features and Technical parameters 1. Adopt to the independent intellectual property rights of rotating magnetic field non-contact magnetization, magnetic field distribution more uniform, use and reliable 2. Testing parts hang vertically, so it can test without removing the spreader, reducing the chucking process, it is really easy and efficient to operate; 3. Magnetizing current controlled by SCR module of voltage regulation, current can be adjusted at any time according to the need of the inspection 4. Using fluorescent magnetic powder detecting, magnetic marks have higher contrast ratio; 5. PLC program control spray and magnetization process, which reduce the impact of human factors testing; 6. Adopting the attenuation demagnetization in situ, it is easy to operate and have a small remanence; 7. Magnetizing device vertically, appearance is concise and cover an area of an area small, less magnetic suspension vertical flow loss 8. Magnetization mode: Rotating Magnetic Field 9. The current of magnetization: 0-2500A continuously adjustable 10. Wellhead size: 300×300,395×175,400×400,500×350,660×620,750×750,800×600,900×700,1200×600,1200×700,1250×500,1350×970mm,etc.Can be customized 11. The central magnetic field strength of the magnetized device: ≥2400A/m 12. Detecting sensitivity: Clearly displays the artificial faults of A1 standard test piece 15／50; 13. Residual Field: ≤0.3mT
