Draining The Test Cell Of Oil - Ametek CHANDLER ENGINEERING 7322 Instruction Manual

4. If the program status light is displayed on the temperature or pressure controller screen,
press the F2 button to stop the program. Press the F1 button to toggle to Manual Mode
(the Hand indicator
5. Start cooling the cylinder by placing the Coolant Switch to the ON position.
Allow the cylinder to cool to 190º F (90º C) or less before continuing to the next step.
The following steps are necessary in order to transfer the hydraulic oil from the pressure
cylinder back into the reservoir. When cool-down is complete, set the pump switch to 'Off.'
Warning: When the temperature of the sample is above 212°F, leave at least 500
psig on the sample during cool-down.
Warning: If the cylinder is opened while its temperature is above 100°C (212° F),
steam will escape, and the operator can be injured! Be sure the cylinder
temperature is below 100°C (212°F).

Draining the Test Cell of Oil

After the cell has cooled and all of the pressure has been relieved, perform the following
steps to drain the oil.
1. Open the T-handled manual pressure release valve to relieve pressure in the cylinder
(slowly opening and closing the valve to release pressure in increments will prevent
rupture of the slurry cup diaphragm).
2. Set the "Cylinder" control rocker switch to the 'Drain' position to transfer the oil from
the cylinder into the reservoir. (Completion of the oil transfer will be indicated by a
bubbling or hissing noise in the reservoir.)
3. Set the "Cylinder" control rocker switch to the 'Off' position to stop the oil transfer.
4. Loosen the thermocouple seal gland to vent the remaining air pressure from the cylinder.
Warning: If the cylinder is opened while its temperature is above 100ºC (212 ºF), steam
will escape, and the operator can be injured! Be sure the cylinder temperature
is below 100°C (212°F).
5. Remove the thermocouple from the cylinder head.
6. Remove the cylinder head by tapping the cylinder head handles with a rubber mallet to
jar the head loose and then remove the head itself.
7. Using the pot mech bail, reach into the cylinder and remove the pot mech.
8. Using the slurry cup bail, reach into the cylinder and remove the slurry cup. The cup
should be immersed immediately in a container of cold water.
9. Clean the slurry cup thoroughly and coat it with grease. Also, disassemble and clean the
diaphragm hub and apply grease liberally to the hub O-rings.
