ASTM D2272 Rotating Pressure Vessel Oxidation Stability Test for Lubricating Oil

Product Description

What is the purpose of an oxidation stability tester?

1. Monitor the change of the oxidation stability of the lubricating oil to prevent the oxidation and deterioration of the lubricating oil from generating more organic acids and causing corrosion of the lubricating parts of the equipment.
2. Prevent more sludge, colloid and asphaltenes produced due to serious oxidation of lubricating oil, increase the viscosity of lubricating oil, which is not conducive to the lubrication and heat dissipation of equipment. It also prevents the flow of lubricating oil from being blocked by too much oil sludge and increases the wear and tear of equipment.
3. The oxidative deterioration of lubricating oil will also cause the cracking and failure of the additives of the oil, and the deterioration of the relevant physical and chemical properties of the oil, such as the foaming, emulsifying, and anti-wear properties of the oil will be significantly reduced.


 

How to perform RPVOT detection?

1. Weigh the used oil and 5 g of distilled water into the reaction vessel for testing.
2. Polished copper coils were added to the mixture to catalyze the reaction, and the vessel was secured to the stainless steel vessel.
3. Manometers record the internal pressure of vessels and equipment. The container and equipment are filled with pure oxygen and the pressure is 620kPa
4. The copper coil and the oil-water mixture are rotated for 60 revolutions under the pressure of 150°C. Initial heating will result in an increase in pressure within the vessel.
5. Oxygen and copper, water, temperature will accelerate the oxidation process, consume internal oxygen, and cause a drop in pressure.
6. The measured variable is the duration until the internal pressure drops by 175 kPa from the maximum value.

What are the test methods for lubricating oil oxidation stability tester?

1. Rotating Bomb Oxidation Test (RBOT) method
The rotary oxygen bomb method is to put the oil sample, water and catalyst into a glass sample container with a cover, and place it in the oxygen bomb equipped with a pressure gauge. The oxygen bomb is filled with 620kPa (90psig) oxygen, put into the specified constant temperature oil bath, and make it rotate axially at an angle of 300 with the horizontal plane at a speed of 100r/min. The time (min) required for the test to reach the specified pressure drop is the oxidation stability of the sample. In addition to the difference in metal catalyst, test temperature and oxidation bomb, the main difference between the two is the difference in the amount of oil sample, the latter is 50g, while the former is only 1.5g, so the former is called thin layer Determination of Oxygen Oxidation Stability.

2. Oxidation tube test method
Oxidation tube test method refers to that under the condition of metal catalysis, a certain flow of air or oxygen is passed into the sample, and at a certain temperature, after oxidation for a specified time, the acid value, viscosity, carbon residue increase value and other indicators are used to characterize the lubrication. The degree of oxidation of the oil. Since the test time of the oxidation tube test method is mostly long, and some even reach 312h, the condensation of lubricating oil is also a very critical factor.

3. Equipment simulation test method
The equipment simulation test method refers to adding oil samples to the simulation equipment to simulate the actual working environment of different lubricating oils. Indicators such as the change of the catalyst and the catalytic metal sheet represent the oxidation degree of the lubricating oil.
