CYLINDER LINER DEFECTOSCOPE
An automation system for inspection of cylinder liner of diesel engine, basis on eddy
current method. It allows reliably verifies cracks and porosity of cylinder liner in less then 13 seconds.
The liners are clamped and put into rotation. Four probes do the scanning for the purpose
detection of surface, subsurface cracks and porosity on the outer diameters of the liner while five probes scans the inner
diameter. When a defect appears under any probe the rotation is stopped. On the schematic picture of the liner, located on
a control panel of defectoscope, a light indicator will burn up indicative, under which probe a defect is located.
Then with help of portable eddy current defectoscope with hand-held probe (pencil type) it
is possible to find the exact place of location of crack and its extent.
