Air release value measuring instrument

KSD-6Air release value measuring instrumentCompliant with SH/T0308 standard, it is used to determine the ability to separate mist from petroleum products such as fire-resistant oil, turbine oil, hydraulic oil, etc., and to measure the air release value of other petroleum products such as hydraulic oil, turbine oil, etc. The instrument consists of heat-resistant jacketed glass test tubes, circulating water bath, air heating chamber, gas pressure gauge, time controller, water level display, etc. It can be widely used in departments such as power, petroleum, chemical, railway, aviation, commercial inspection, and scientific research.

working principle

The sample is heated to 25, 50, or 75 ℃, and compressed air at 25, 50, or 75 ℃ is blown into the sample to vigorously stir it, causing the air to form small bubbles in the sample, known as mist air. After stopping the air, record the time when the volume of mist air in the sample decreases to 0.2%. The air release value is the time required for the volume of mist air in the sample to decrease to 0.2% under the specified conditions of this method, which is the time for bubble separation.
