Compliance with following International Standards:
- ASTM D3427, IP 313 and IS : 1448 (P‑102)
Purpose:
- The ability of turbine, hydraulic, or lubricating oil to separate entrained air is a key performance characteristic in applications where agitation causes a dispersion of air bubbles in the oil. To determine air release properties, the sample is heated to a specified test temperature and blown with compressed air. After the air flow is stopped, the time required for the air entrained in the oil to reduce in volume to 0.2% is the air bubble separation time.
Construction Details:
The entire assembly consists of following parts and accessories to form the complete test apparatus.
- The main unit comprises of an air heater, fine control pressure regulator (Flow meter), pressure gauge, and mounting clip for the test vessel.
- Steel wire for sinker suspension
- Moisture trap
- Pressure gauge specifications : 0.35KPa with divisions at least every 2KPa and an accuracy of 1.5KPa with needle valve
- Manual lifting in slider area to move test vessel from air source to sinker facility
- Integrated touch screen programmable controller with data logging facility
- Integrated Digital automated density balance with stand and sinker to directly measure the density value
- Integrated Digital constant temperature circulating bath with circulating pump of flow rate 10 LPM
- Automatic calculation of final sample density for determination of air release values
Technical Specifications of circulating water bath:
- Excellent control accuracy and uniformity due to its modular and innovative design.
- Outer chamber is made from Galvanized Sheet ‑ which is powder coated in attractive shades
- Inner chamber is fabricated from S.S.304 ‑ Mirror polished material
- Fully argon welded design
- 50mm thick Glass wool Insulation is provided between the inner chamber and exterior body to prevent the direct thermal loss
- Specially designed immersion Heater for heating within the set point temperature
- ISI marked immersion Heater ‑ U shaped
- Built ‑ in boost for initial heating
- Stirring is achieved by an efficient, continuously rated, self cooling motor with SS shaft and propeller of anti ‑ corrosive Material,
- Stirrer is fitted on side of the bath allowing obstruction free usage of working area.
- Circulatory Pump to circulate the bath water to external apparatus
- Entire instrument Works on 230 Volt, 50 Hz, Single phase, AC Supply
