Maintenance:
Time, Temperature, Pressures, Sample Quality, and the number of Sample Cycles will all have
an affect on the need for maintenance.
·
Preventative Maintenance
In general, a preventative maintenance program is for the purpose of trying to anticipate possible
maintenance that will be required and to choose when to perform that maintenance prior to the actual
need for the maintenance, thus eliminating most emergency responses for the maintenance, or
possible ending up with out a sample.
·
Reactive Maintenance
This is when maintenance is only performed as a reaction to the cylinder not being capable of
containing a sample properly due to some type of component fatigue.
Each cylinder must be visibly reinspected at least once a year for deterioration of seals,
scratches, dents, and gouges. Components that are deteriorated or damaged must be replaced
by factory specified parts as shown on YZ drawings. Components may be replaced by the
factory or user, observing Tie Rod Nut tightening torque values. Additionally at least once a
year, the end caps, tie rods, and cylinder must be thoroughly cleaned with appropriate solvent
recommended by the manufacturer. Replace rupture disc every year under normal conditions.
A more frequent change out of the rupture disc may be necessary due to corrosion, fatigue,
temperature, or adverse conditions. These factors must be evaluated by the user through
actual service experience.
However; if the disc is not changed periodically when exposed
to these conditions, premature failure (due to elapsed time or pressure) of the rupture
disc may occur, thereby discharging the process media.
