SECTION 2 – OPERATION
Operating the Curing Chamber
1. Prepare a cement slurry, fill molds and insert the molds into the mold bucket.
2. Add water to the mold bucket while its suspended from the hoist.
3. Place the filled mold-bucket assembly into the chamber.
4. Thoroughly lubricate plug threads and seal ring with "Liqui-Moly" or similar high
temperature lubricant, lower plug into cylinder and screw down firmly to ensure metal-
to-metal seat.
5. Unhook the hoist from the top plug and move it out of the way.
6. Use torque wrench to tighten set screws. See 19-0107 drawing for proper tightening and
torque rating.
7. Install center thermocouple and insert the plug into the jack on the front panel. Screw the
nut into the gland but do not tighten.
8. Open the Fill valve (activate the Fill "Soft" Key) to remove all trapped air in the
chamber. When all the air has leaked by the thermocouple nut and oil appears,
immediately tighten the nut.
Note:
9. Activate the Pump "Soft" Key to Pump the chamber to the desired curing pressure.
Alternatively, enter the desired starting pressure as the Pressure Set Point.
Warning: This pressure vessel is designed to operate at pressures that are
considerably above 10,150 psi/70 MPa. Therefore, we recommend that the
operators shall take all possible safety precautions to reduce the possibility
of an accident.
To Apply Heat To Cylinder
1. Turn physical Heater switch to on and activate the Heater "Soft" key. The red Heater
light will illuminate. The heaters are not enabled unless both the physical and soft Heater
switches are on. Current will not be supplied to the element until a Temperature Set Point
has been entered or a Schedule has been started.
2. Program the desired schedule into the Controller.
To Cool Cylinder at End of Test
1. Turn Heater switch to OFF (either the physical or "soft" Heater switch), allowing the
vessel to air-cool.
2. Set the Pressure Set Point to the desired end-of-test pressure.
3. Cool until the internal temperature is below 38°C (100°F), set the Pressure Set Point to 0
and open the manual Pressure Release valve.
Warning: The instrument could still be hot, use appropriate PPE when removing the top plug
and sample rack.
While removing trapped air, some oil can spill onto the top plug. Thoroughly
wipe off and remove any oil residue to prevent fumes at high temperatures.
