JWT-A Magnetic Particle Flaw Detector for Spring

Applicable scope

It is suitable for locomotive and rolling stock bumper spring, axle box spring and other coil spring of magnetic particle testing

Features and Technical parameters

1. For the structural characteristics of the spring adopting the center conductor (through rod) and direct current flow method to make the spring achieve composite magnetization, ensure the surface of the spring wire spring get availability of sufficient strength and more uniform tangential magnetic field

2. Through adjusting bracket lifting gear, adjusting spring centerline are consistent with the center line of the magnetizer, to meet the needs of the different diameter of the spring of magnetic particle inspection.

3. Magnetizing current controlled by thyristor voltage regulation module,It can be adjusted at any time according to the diameter of the spring.

4. The machine can drive the spring rotate in order to observe the internal and external magnetic marks, enabling semi-automatic flaw detection of the spring

5. Bed struct integration design, without special foundation, easy installation and maintenance

6. Magnetization mode: Center conductor method, Current magnetization method, Resultant magnetic field.

7. Center conductor magnetization current: 0-5000A continuously adjustable

8. Electrified magnetization current: 0-1000A continuously adjustable

9. Electrode spacing:240-600(300-820)mm Adjustable (on demand)

10. The diameter of the spring detected: 70-200mm(200-330) (on demand)

11. Detecting sensitivity: Clearly displays the artificial defect of A1 standard test piece 1550

12. Residual Field: ≤0.3mT

13. Mainframe exterior size: 2.1×0.8×1.4(3.485×1.868×2.05)m

14. Mainframe weight: 800kg
