Product Description

Automatic Lubricating Oil Oxidation Stability Tester

The fully automatic lubricant oxidation stability tester that complies with ASTM D2112 and D2272 standards is an intelligent device designed based on the rotating oxygen bomb method, used to simulate the evaluation of the antioxidant performance of lubricants under high temperature and high pressure conditions. The testing process of the oxidation stability tester is fully automated, and there is no need for personnel to be on duty throughout the entire testing process, allowing for automatic judgment of experimental results. And it can further improve detection efficiency and result reliability. This oxidation stability tester is widely used in optimizing additive formulations in refineries, evaluating the remaining life of turbine oil in power plants, and standardizing testing by quality inspection agencies.

ASTM D2272 Standard Test Method for Oxidation Stability of Steam Turbine Oils by Rotating Pressure Vessel

The principle of oxidation stability tester:

The core principle is to place the quantitative sample, distilled water, and copper catalyst coil in a sealed oxygen bomb, fill it with a specified amount of oxygen, and rotate it axially at a speed of 100r/min ± 5 in an oil bath at 140 ℃ (D2112) or 150 ℃ (D2272). By monitoring the time when the oxygen pressure drops to 175 kPa (i.e. the oxidation induction period), the oxidation stability of the oil can be determined - the longer the time, the stronger the antioxidant capacity.

Features:

The metal measuring cell reduces the unpleasant odor emitted by the medium oil during testing and eliminates the potential dangers that may arise due to prolonged experimental time.
The oxidation stability tester can automatically perform detection, calculation, and control, and there is no need for personnel to be on duty during the entire testing process, with a high degree of automation. Automatically judge experimental results.
Easy ventilation, no need to place in a fume hood, exhaust gas and odors can be easily discharged through plastic pipes.
The oxidation stability tester can calibrate temperature and pressure to ensure the accuracy of pressure and temperature.
Automatically record data and test results during the testing process. It is possible to query and compare past records, and print pressure change curves. Automatically determine the pressure inflection point and end the test automatically.
The oxidation stability tester adopts a low-power design, with a single testing unit of only 1300W.
