Fluorescent inspection system

More efficient and economical inspection systems

Fluorescent penetrant inspection systems, with that a large amount of test objects can be inspected efficiently and economically, have been widely used for precise inspections of various types of parts including those in the aviation industry. NEOGLO-UNITS have been designed and madeto satisfy users’ needs adequately by making full use of “know- how “cultivated in long-term experiences and abundant sales achievements.

Eishin’s & J.N.S. (2003) penetrant inspection systems are mainly divided into fourtypes.Test objectsaretransferredmanuallyby handor with hoists. Automatic system is also available. Every inspection process can be automated from penetration to inspection,andthe test objects are transferred automatically.

Specifications

EF-A type system

Small-sized penetrant testing system (about 5m in total length) for small and light weight test objects. Basically, test objects aremanually transferred between the stations.

EF-B type system

Medium-sized penetrant testing system (about 10m in total length) for large and heavy weight test objects. Usually, test objects are transferred on the roller conveyer between the stations. Each station is equipped with a lifter or a door.

EF-C type system

Large-sized penetrant testing system (more than 10m in total length) for mass-produced parts. The test objects are automatically transferred on the independently-driving roller or chain conveyer.

EF-D type system

EF-D type system is equipped with the waste water treatment system dedicated to separate-type water washable fluorescent penetrants. Rinse water can be recycled with this system.

  • Waste water treatment systems for standard penetrants (MIZUSUMASHI)are also available.
  • Custom-designed system is available.

Inspection

Procedures for fluorescent penetrant inspection

Fluorescent penetrant inspections may be performed in three methods. Select any of these methods and the type of the penetrant to be used depending on the material type of test objects, the surface condition and the defect type.

Demagnetization

Demagnetizing power supplies/power units

For complicated-shape parts, it has been very difficult to demagnetize down to 3 gausses or lower so far. This type has overcome such a problem. Combination of a power supply and various types of coils enables the user to select the desired demagnetizing technology.

Demagnetizer

There are many technologies for demagnitization. Encircling coil or box-type demagnetizers are commonly used. With the encircling coil type, demagnetization can be done in several ways satisfying the user’s needs. The box-type is useful for inspections on small-article parts and thin steel sheets.
