Piston Cylinder Apparatus(Depths of the Earth)
TheQUICKpress is a small, easy to use device that generates very-highpressures athigh temperatures. MECHANICS Itis used forhot isostatic pressing, thermodynamic studies, electrical studies,new materialssyntheses that include the development of novel ceramics,high-Tcsuperconducting structures, amorphous phosphides and nitrides,andtechnologically important metal-hydrides, as well as many other topicsinmaterials engineering science. SELECTEDAPPLICATIONS
Very-highpressure generating insturments of the QUICKpress type arereferred to aspiston-cylinder devices and have been in use since 1955. Earlymodels were massiveand difficult and expensive to manufacture and operate. Thedesign describedhere (first developed in 1977), underwent major modificationsin 1988 tofurther improve the apparatus. SPECIFICATIONS Asa consequence, ease of operation increased, while expense of productionandoperation decreased. At present, very little operator training is requiredtodo high-pressure high temperature piston-cylinder experiments, EXECUTINGEXPERIMENTS although a great deal of scientific experienceand creativity may be needed toformulate experimental programs and interpretresults. CAPSULES
TEMPERATURECONTROL UNIT
Depthsof the Earth Company’s temperature control unit sets and monitorssampletemperature, furnace current and voltage, and cooling waterflow. Expressly designed for the QUICKpress, the temperature control unitwillcontrol any process equipment that utilizes AC output to power resistiveorinductive loads.
KEY FEATURES:
Auto or Manual Microprocessor-based interface sets and monitorstemperature.
High-current phase-angle fired thyristor controls heating rate, coolingrate, or set-point temperature.
Single Segment programmable ramp/soak with max rate: 100°C/minute and min.rate: 3°C/minute
Unlimited run-duration
Control Signal instant switching between thermocouple types R, S, C, J, E,T, L, N, B
Automatic shut-down at temperature over-range, voltage or current outputover-range, cooling water system failure, or power outage. Mechanicalrelay prevents automatic start-up after any alarm condition is restored.
