In order to locate
cracks or holes in the engine heads, all parts are capped by a plate and
rubber pad. This is done
via use of hydraulics coupled to clamping arms and forming an assembly
called a CAGE. The test is
performed under water with the head given an air pressure.
The water is heated and causes small cracks to open so air will
escape. The operator looks
for any air bubbles and will mark these areas.
To look at all sides of the head the clamping cage is made to
rotate via hydraulics. Water level
can be adjusted instantly via means of air pressure forcing water out of
a double chamber test tank. We can move 52
gallons of water into the test area completely covering the head under
test in less than 2 seconds by this means. Also the test area
is illuminated via underwater lighting.
PLC controls are used to operate the various parameters.
