Chapter 7
OPERATIONAL PROBLEMS
1. PHENOMENON NOTED
If a test machine begins to detect too many bad parts (statistically, more than three
consecutively), it is advisable to carry out a check on the whole unit. The quality of the
manufacture and operation of the leak detector should be the last things considered.
1.1. CONDITION OF THE MACHINE'S SEALS
This is the no.1 defect as the seals are subject to high levels of dirt contamination
(alumina, shavings). Regular cleaning of the seals is an effective remedy.
1.2. DAMAGED INSTRUMENT SEALS
There is a possibility that the seals may be cut by shavings or worn by repetitive
squashing. This can be prevented by regular servicing and replacement of the seals.
1.3. BUMPER PAD
This is a defect which may occur after a certain amount of time as the bumper pads
may be worn, or if the pressure settings in the air cylinder are inadvertently disturbed.
Check the stability of the measurement and that the bumper pads are correctly installed.
1.4. PNEUMATIC AIR SUPPLY TOO LOW
This anomaly can cause false measurements (large leaks or erratic measurements).
The air supply to the cells must be higher than the minimum of 4 bar and it is essential
that it is greater than the minimum test pressure of 1 bar. Also check that sealing
connectors are being used correctly.
1.5. PNEUMATIC LINK
The link and reference pipes will age and break with time. The pipes and seals must
conform to the required quality. ATEQ recommends the use of RILSAN PA11 pipes and
AVS type joints.
