| Air release properties of Petroleum Oils |
| Test Method |
The ability of a
turbine, hydraulic, or lubricating oil to separate entrained air is a
key performance characteristic in applications where agitation causes
a dispersion of air bubbles in the oil. To determine air release properties,
the sample is heated to a specified test temperature and blown with compressed
air. After the air flow is stopped, the time required for the air entrained
in the oil to reduce in volume to 0.2% is the air bubble separation time. |
| Features and Benefits |
• Complete
instrument and data acquisition system exclusively designed for conducting
ASTM D3427, IP 313 and related test methods • Powerful software system for Windows®-based PC platforms automates sample density measurements as well as the calculation of the air release value, the first order rate of air release, and the volume percent air versus time • High accuracy temperature control with digital setpoint and display • Digital control panel leads user from start to finish of test operation • Automatic calculation of final sample density for determination of air release value • Redundant overtemperature protection circuitry assures safe operation |
| K88500 Air Release Value Apparatus |
Air Release Value
Apparatus consists of a test vessel and air flow control equipment for
delivering heated air at the specified flow rate to a lubricating oil
sample maintained at constant temperature. Microprocessor-based control
panel guides user from start to finish of the test procedure, calculates
sample target density, and provides the time operation for measuring the
air release value of the test sample. The system includes drying oven
for warming the test oil at temperatures of up to 100°C; circulating
bath with digital temperature controller and air bath for sinker; compressed
air heater with digital temperature controller, overtemperature and overpressure
protection; pressure gauge; thermometer; jacketed sample tube with air
inlet/outlet tubes and baffle plate. |
