Rupture Disc
The Curing Chamber is assembled with a rupture disk (#122-052) which is
rated for a maximum of 5,500 PSI. It is a solid metal preformed differential
pressure relief device which is used to protect the system from an
overpressure condition. The rupture disk provides instantaneous full-opening
within milliseconds of an overpressure situation.
The main symptom of a blown rupture disk that the system will not be able to
build pressure.
The rupture disk is located in the back side of the Curing Chamber.
To replace the rupture disk:
1. Turn the Curing Chamber off and depressurize the air system.
2. Use a phillips head screwdriver to remove the rear panel.
3. Use a
⅝"
wrench to remove the top and bottom tube fittings to the high
pressure tee.
4. Use a
9/16"
wrench to remove the high pressure tee assembly from the
outlet tube fitting.
5. Orient the tee assembly so that the outlet port faces up.
6.
Use two adjustable wrenches to remove the outlet fitting and gain access
to the rupture disk.
7. Replace the rupture disk (#122-052), reassemble the housing, and
reinstall the tee assembly to the tubing.
8. Replace the rear panel.
