C,Inspection areas

Can meet the 300mm in diameter less than, length is 2540 mm of small and medium-sized parts within surface and near surface there may be slight defects.

D, Design requirements2,Main mechanical design requirements

2.1 Mechanical main body frame is made of high quality steel, and it is tough and firm..

  4,Magnetization power control system

Longitudinal and circular magnetization currents are supplied independently with the help of two separated transformers. Solid-state relay controlled and Phase shifting trigger circuit stepless.

5,Electric control system6,Spraying, agitation, filtration and recycling system of magnetizing suspending liquid7,Longitudinal magnetization coil

7.1,A mobile magnetized coil,inner diameter 400mm.

8,The human-machine interface control system 

   11,Automatic demagnetization system

Attenuation type automatic demagnetization.

12,Equipment has to be automatic alarm function

When the main transformer temperature rise more than design standard, or when magnetizing current flow, owe flow appeared when automatic alarm equipment.

13,With the phase control power function

For residual magnetism method detection.

14,High integration the periphery of the circuit

For Solid-state relay controlled for phase control,promise DiaoLiu,with non-contact, no interference, no noise, operation simple, reliable performance, etc.
