Abstract:
Air contamination in the fluid is a major concern that can cause severe damage to machinery and negatively influence its reliability. In most hydraulic and lubricating oil systems, lubricants will be polluted by contaminants in four main forms, dissolved, entrained, free, and foam. These contaminants can cause numerous problems, such as excessive noise, thermal degradation, and cavitation, and can also shorten equipment lifespan and compromise lubricant integrity. To avoid complications and corrosion when selecting lubricants for varied applications, it is important to measure their air-release properties, so that they can undergo an appropriate air releasing process prior to their application.The Koehler K88530 Air Release Value Analyzer is an innovative instrument that can beintuitively used to determine air-release property. Its highly integrated and automatic advantages lead it to become not only powerful but also user-friendly. With its high-performance screen, users can operate this machine precisely and read all necessary data easily. The analysis method this device used is ASTM D3427 Standard Test Method for Air Release Properties of Petroleum Oils. The unit heats samples to a specified test temperature before blowing them with compressed air. Subsequently, the instrument can measure the air bubbles’ “separation time” by the time required for the air contamination to decrease to 0.2% by volume after stopping airflow. Then it will give users the result directly and also provide further data storage and transmission support.
