Distinguish Magnetic Field Strength Portable Pie Gauge Magnetic Filed Indicator HFI-100
The magnetic field indicator is in accordance with China's standard JB3965-85,
JB4730-94,and America Recommended Method for Magnetic Particule Inspection ASTME709 Standard and ASTMA275 Steel Forgings
"Magnetic particle testing for steel pressure store" and "magnetic particle testing for pressure vessel forgings".
Particule Inspection Design it is not only suitable for pressure vessels, but also for general mechanical products,
it is a good tool necessary for magnetic particle flaw detection.
It can check the comprehensive performance of flaw detection equipment,
magnetic particle magnetic suspension and the appropriate operation method.
We can easily use it to reflect the intensity and direction of the magnetic field in the magnetized area.
|Magnetic field indicator:
1. Magnetic field indicator is suitable for magnetic particle inspection of steel pressure vessels and general mechanical products.
2. Magnetic field indicator is suitable for magnetic particle inspection of forged steel parts and general mechanical products.
When using Type 1 magnetic field indicator, hold the handle by hand, use the copper face up, eight line surface is attached to the workpiece;
Using type 2 magnetic field indicator, hold the handle by hand so that either side of the magnetic field indicator is attached to the workpiece.
Type 1 and Type 2 magnetic field indicator continuous method inspection, when the magnetic powder or magnetic suspension after spraying, the magnetic field indicator surface appears clear and discernable magnetic trace lines, it means that magnetic effect has been produced, when the magnetic field indicator does not form a magnetic trace or in the desired direction, should change and adjust the magnetization method.
Type 3 magnetic field indicator is copied from West Germany.
It can not only check the flaw detection equipment, but also check whether the comprehensive performance and operation method of magnetic particle magnetic suspension is appropriate.
It can be conveniently used to reflect the intensity and direction of the magnetic field in the magnetized region
It can also adjust the distance between the cover and the soft iron to find the limit value of the ability to observe and discover the buried depth of the near surface defects under a certain magnetic field value.
The magnetic field indicator consists of a flat, non-remanent shield ring like this, inside of a shield ring like this.
A cylindrical soft iron consisting of four parts is provided.
The four parts are separated from each other by non - magnetized slits to form two perpendicular slits on which a cover is rotated.
The pitch of the cover is 0.5mm, and every 90 degrees the cover is engraved with 1, 2, 3, and 4 letters. There is a thin brass plane on the cover, and the distance between the cover and the soft iron cylinder can be adjusted by rotating the cover.
When you examine the device on a magnetized piece, a portion of the magnetic field line is formed through the soft iron column. If the magnetic powder and magnetic suspension are sprayed, a corresponding gap in the cross-shaped crack in the lid will appear according to the direction of the magnetic field.
Rotate the cover 360 degrees, which means that the cover is 0.5mm away from the soft iron cylinder. Continue to rotate the cover and increase the distance between the cover and the soft iron.
If the magnetic particle display still does not disappear.
To determine the direction of the magnetic field, the magnetic field indicator can be rotated slowly in place until the crack is most visible, at which point the magnetic field is perpendicular to the crack shown.
