Key steps in the use of magnetic particle flaw detectors

Magnetic Powder Flaw DetectorsThe suitable probe should be selected according to the workpiece of the flaw detector before use.

First the output cable probe connection is tightened, then the other end of the output cable is inserted into the "output" socket on the panel and tightened.

Plug the power cable and probe into the input power outlet in the panel, insert the other end into the single-phase 220V power outlet (the Power distribution board with 220V must be grounded), turn on the power switch on the panel, and the power indicator light is on, indicating that the control circuit has been plugged in.

The handheld probe will contact the probe with the workpiece under test. Spraying magnetic powder or magnetic suspension on the workpiece is then pressed on the probe hand on the magnetizing switch, "magnetization indicator" light, work is magnetized state; loosen the button switch, observe whether the workpiece has magnetic powder, the workpiece is cracked. In the magnetization process, there are cracks in the local coalescence of magnetic powder, forming a magnetic mark.

The magnetic particle flaw detector has the choice of AC/DC current, when the DC flaw detection is needed, the switching switch is turned to the DC position, at which time the probe working current is the DC output.

If you need to adjust the magnetic pole spacing, loosen the adjustable joints of the butterfly nut to change the magnetic pole spacing of the probe, after adjustment to tighten the nut before you can work.

When the workpiece is magnetized, that is, press the probe hand on the magnetizing switch, the time should not be too long, generally only 3-5 seconds, the long time will cause unnecessary heating and energy consumption.
