Shandong IPRE Inspection Technology Co.,ltd

Preface:

Based on the principle of the magnetic interaction between the leakage field and the magnetic powder, the multi-functional magnetic particle flaw detector can accurately and intuitively display the shape, position, size and severity of the defect, and determine the nature of the defect. The instrument adopts a variety of magnetization methods and can detect various parts of the workpiece. It is widely used in the detection of defects in petroleum, chemical, metallurgy, shipbuilding, aviation, railway and other fields. instrument.

IPRE@CDX-Ⅲ series magnetic yoke flaw detector is a new type of magnetic particle flaw detection equipment designed and produced by our company, which absorbs the advantages of similar products both domestically and internationally. The use of external magnetic field magnetization method makes the instrument have the advantages of small volume and light weight. A highly integrated circuit enables a device to perform all the functions of several original devices, and the instrument can be equipped with four types of probes: A, D, E, and O.

Work Principle:

Place the object of ferromagnetic material to be tested in a strong magnetic field or pass a strong current to magnetize it. If there are defects (cracks, folds, inclusions, etc.) on the surface of the object or near the surface, the magnetic field lines will generate magnetic flux leakage near these defects. , when the magnetic powder with good magnetic permeability (usually magnetic iron oxide powder) is applied to the object, the leakage magnetic field near the defect will attract the magnetic powder, pile up to form visible magnetic powder traces, and form visible magnetic traces under suitable light , so that the position, size, shape and severity of the continuity are not shown, and the defect is revealed.

Function options:

• A-type probe: horseshoe magnetic yoke fillet weld probe, movable joint inclined magnetic head, equipped with work light; Especially suitable for detecting irregular surfaces and complex shaped workpieces. Pole distance: 20-160; Lifting force: AC ≥ 5, DC ≥ 18. Equipped with an electromagnetic yoke fillet weld detector, the probe adopts a movable joint and can be freely adjusted for a wide range of use.
• E-type probe: cross yoke probe or rotating magnetic field probe, which can conduct all-around magnetization flaw detection at one time, and walking roller and working lamp can improve the flaw detection speed. Pole distance: 110, lifting force: AC ≥ 8. A rotating magnetic field flaw detector is equipped, and the two crossed magnetic yokes adopt the alternating current phase shifting technology to generate a composite rotating magnetic field that changes with time, so as to comprehensively magnetize the workpiece at one time. The probe has fast speed and high detection quality.
• D-type probe: electromagnetic yoke probe, multiple movable joints, high magnetization. Pole distance: 60-220, lifting force: AC ≥ 6, DC ≥ 20. An electromagnetic yoke fillet weld flaw detector is equipped, and the probe is characterized by high magnetic conductivity, high magnetization, etc.
• O-type probe: also known as a circular probe, with an inner diameter of 150 and a central magnetic field of ≥ 1800e. Equipped with a circular flaw detector, it is designed based on the principle of generating a strong magnetic field when the coil is energized, suitable for segmented flaw detection or demagnetization of complex workpieces such as shafts, pipes, bolts, etc.
