Product Description

ASTM D3427 IP 313 ARV Air Release Properties of Lubricant Oils Tester

Why do we need to measure the air release value of lubricants?
Air release is very important for hydraulic oil, because air in hydraulic oil has many hazards: increasing the compressibility of hydraulic oil, compression will increase the oil temperature, shorten the service life of hydraulic oil, and cause cavitation damage to hydraulic pumps. Therefore, the hydraulic oil should have good air release properties, so that the air bubbles in the hydraulic oil can quickly escape and discharge in the oil tank, so as to prevent the air bubbles from continuing to circulate with the hydraulic oil.

Test method:
When using the instrument, the sample is heated to a certain temperature, and the sample is vigorously stirred by blowing excess compressed air into the sample, and the air forms small bubbles in the sample, that is, mist air. Record the time when the volume of mist air in the sample decreases to 0.2% after the gas is stopped.

Features of air release value of lubricants:
1.Conforms to ASTM D3427, IP 313 and related specifications
2. Integrated Touch Screen Control Panel
3. Automatic Lift System that moves test vessel from air source to balance sinker
4. Automatic calculation of final sample density for determination of air release value
5. Integrated Circulation Bath with water level indicator
6.Integrated Balance
7.Secure Clamp Mechanism of the air tube
8.Automated Jacketed Test Vessel draining
9.Operator Safety: Protective safety shield around vessel
10.Ease of Use: Removes traditional operator problems and Sinker is permanently fixed to balance and sample raised up over it
11.Precision and Accuracy:Automatic timing and regulated aeration ensures stable density and test repeatability
12.Enhanced Test Throughput:Temperature control minimises sample heat loss and speeds up start of test

What is ASTM D3427 Air Release different from ASTM D892 Foaming Characteristics testing? 
The air release test measures how quickly air bubbles rise and leave an oil sample, whereas the foam test is measuring the volume of air bubbles once they rise and gather at the top of the sample, and how long they last. The sample's foam tendency (how much foam is generated) and foam stability (how long the foam lasts) is recorded during the foam test (tested at 24 °C and 93 °C). 
The air release test forms larger bubbles than the foam test. The main difference is how the air is introduced into the sample. With the foam test, a porous, spherical stone diffuser is immersed at the bottom of the sample. The air release test uses an open ended tube near the bottom of a tall cylindrical test vessel. The air flow is maintained at a specified back pressure and many large bubbles form and rise through the sample. The foaming characteristics of an oil can typically be improved by anti foam additives, which reduce the surface tension of the oil air release cannot. The ability of an oil to release the entrained air is primarily a physical property of the
oil itself.
