Today borescope testing gains more and more popularity. But some
technicians doubt if they have enough skills to work with an inspection camera. However
working with it does not require special knowledge or
skills. There are some simple rules to follow.
First of all it is necessary to determine the correct length and
diameter of insertion probe. Then you have to think about what is better to use
– rigid or flexible probe. If you need to document your inspection, you would
need an inspection camera, which has a special monitor hub with
recording ability.
With the help of an optical borescope you will perform a visual
inspection through a device eyepiece. Insert the probe with caution through
the inlet and switch on the light source. You will immediately see the desired
area. In case of an inspection camera turn the power on to activate the device and the
light source, and insert the probe. If light intensity is too strong, you can
gradually decrease it. Press on recording button and your video will be
recorded in AVI or other format onto an SD card.
Remember that borescope probes are rather fragile; therefore it is
better to avoid excessive bending or forcing.
Here is an example of using an inspection camera to
inspect a car engine. When a
car has an interference engine, if the timing belt failed, it is quite possible
that the pistons hit valves before the engine stopped completely. After a compression
test, if the valves are bent they will not seal properly, and the compression
readings will be low. Then you can take a scope and inspect through the
spark plug holes and look for impressions on the piston tops. Inspection cameras with 2
meter long probes and tip articulation are the most convenient for this kind of
inspection. The flexible probe will show the damage that may
have occurred without disassembling the top part of the engine.
