In sTEm-at-Work Puzzle #35 the technician for Sun Hydraulics performed
the quality check on a hydraulic
driven actuator before it was to be shipped to
the customer. After examining the test
results shown in the graphic below, the Tech did not send the actuator to the
customer, but instead, sent it back for rework because the actuator leaked. The
leak test involved the application of the pressure pattern shown to the
right. The Tech knew that the value was
not supposed to leak when the pressures in the test pattern were applied to the
hydraulic fluid in the actuator.
The Tech rejected the actuator
because the test results shown below were not the same square wave shape as the
applied pressure test pattern shown above.
