Oxidation tester, aviation hydraulic oil, thermal oxidation safety testing, glass instrument

This standard specifies the method for determining the thermal oxidation stability and corrosion of aviation hydraulic oilOxidation tester, aviation hydraulic oil, thermal oxidation safety testing, glass instrument

Test steps

7.1 Take 100mL of the sample and clean it. Fucking divorce

72. Place the metal sheet prepared with 642 on the emblem where the sample has been installed

In the oxidation tube, the connection between the bottle stopper and the oxidation tube is heated to the test temperature using a precision ellipsometer

In 609, the oxidation conditions are determined according to the technical requirements of the oil product, and the combustion sample micro reactor is kept vertical and free of gas,

Introduce cooling water into the condenser tube of the national flow, connect the air float through the dry micro and micro borrowing meters, and supply gas to the oxidation tube to adjust the gas flow rate

Stabilize it at 5Lh ± 0.Lh, and record the oxidation time at this time

7.3Oxidation tester, aviation hydraulic oil, thermal oxidation safety testing, glass instrumentAfter the experiment reaches the specified time, cut off the heating electricity and replace it with cold water, and lift it up from the oil bath for oxidation measurement

Cool the device at room temperature for 30-40 minutes, remove the oxidation flame, carefully separate the pieces into groups and place them on filter paper. Pour the sample over and clean it

The conical flask is ready for use. 74 metal sheets are washed and dried one by one, then dried on paper and placed in a weighing bottle. They are then transferred to a dryer

After being placed in the balance room for 30 minutes, weigh to the nearest OUm

7.5 After oxidation, measure the acid value of 50T and 5NC24 according to CBT 265
