This standard is a vital tool for those involved in the formulation, testing, and application of steam turbine and other oils. It provides a systematic approach to evaluating how these oils release air, which is a critical factor in maintaining the efficiency and longevity of machinery.

Understanding the Impinger Method

The impinger method, as outlined in this standard, is a precise technique used to measure the air-release properties of oils. This method is particularly important for steam turbine oils, where air entrainment can lead to reduced efficiency and potential damage to equipment. By following the guidelines set forth in BS ISO 9120:1997+A1:2019, professionals can ensure that their oils meet the necessary performance criteria.

The impinger method involves the use of a specialized apparatus to simulate the conditions under which oils are used in real-world applications. This allows for accurate measurement of the time it takes for entrained air to be released from the oil, providing valuable data for quality control and product development.

Why Air-Release Properties Matter

Air-release properties are a critical aspect of oil performance, particularly in high-speed machinery such as steam turbines. When air becomes entrained in oil, it can lead to a range of issues, including:

• Reduced lubrication efficiency
• Increased risk of cavitation
• Potential for foaming, which can lead to overflow and contamination
• Increased wear and tear on machinery components

By understanding and controlling the air-release properties of oils, operators can enhance the reliability and efficiency of their equipment, leading to longer service life and reduced maintenance costs.

Applications of BS ISO 9120:1997+A1:2019

This standard is applicable to a wide range of industries and applications, including:

• Power Generation: Ensuring the efficient operation of steam turbines and other power generation equipment.
• Manufacturing: Maintaining the performance of machinery and equipment in industrial settings.
• Automotive: Enhancing the performance of lubricants used in engines and other automotive components.

• 75.100 Lubricants, industrial oils and related products

This International Standard specifies a method for the estimation of the ability of a petroleum-type steam turbine oil to be separated from entrained air.

NOTES

1. The impinger method described in this International Standard is used for determining the air-release ability of the oils tested. Air bubbles dispersed in the oil influence the compressibility and can cause malfunctions. This method may not be suitable for ranking oils in applications where residence times are short and gas contents high.

2. Agitation of lubricating oil with air in equipment such as bearings, couplings, gears, pumps and oil return lines, may produce a dispersion of finely divided air bubbles in the oil. If the residence time in the reservoir is too short to allow the air bubbles to rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system. This may result in an inability to maintain oil pressure (particularly with centrifugal pumps), incomplete oil films in bearings and gears, and poor hydraulic system performance or failure.

3. This test measures the time for the entrained air content to fall to the relatively low value of 0,2 % (V/V) under a standardized set of test conditions, and hence permits the comparison of the ability of oils to separate entrained air under conditions where a separation time is available. Although the significance of the test results is not fully established, sponginess and lack of sensitivity of the control systems of some turbines may be related to the air release properties of the oil. System design and system pressure are other variables.

4. For the purposes of this International Standard, the expression "%(V/V)" is used to represent the volume fraction of a material.
