JLH-A Magnetic Particle Flaw Detector for Bumper Box Applicable scope For MT-2, MT-3, ST bumper box and other models both inside and outside surface of the magnetic particle testing. Features and Technical parameters 1. The composite magnetic device by central conductor circumferential magnetization and the induction method longitudinal magnetization meet box mouth and internal and external surface detection requirements 2. Testing work-pieces adopt semi-automatic ball track transportation, matching the rotatable observation elevator, which is easy for going up and down work-piece and observation to judge the detection flaw, the operation is convenient and efficient 3. Adopting the import PLC programmable controller during the whole detecting process, so it is simple and credible to operate 4. Adopting advanced electric power compensation and controlling technology, reducing the power consumption 5. Adopting attenuation measure of magnetization current’s difference value, It can demagnetize automatically and has little residual field when shut off the power. 6. Bed struct integration design, without special foundation, easy installation and maintenance 7. Magnetization mode: resultant magnetic field 8. The maximal peak value current of circular magnetization: 0-3000A continuously adjustable 9. Longitudinal magnetization MMF:≥10000AT 10. Detecting sensitivity: Clearly displays the artificial defect of A1 standard test piece 15／50 11. Residual Field: ≤0.3mT 12. Work line height :550mm 13. Work ling width: 345mm 14. Mainframe weight:1260kg 15. Mainframe exterior size: 1.8m×0.86m×1.89m
