White Paper: Automotive
There are five major problems associated with aerated oil that can be deadly to hydraulic systems. Depending on the design of a hydraulic tank, the application and aeration severity, it is possible that all of these conditions could be happening at the same time. The primary purpose of oil is to lubricate, transfer power and thermal energy. Air can significantly impact the performance of the oil with potentially severe consequences. Oxidative and thermal degradation, impaired heat transfer and gaseous cavitation are just some of these problems. This white paper examines the symptoms and effects of each of these phenomena and their impact in poor designs.
Topics such as dampening, oil density reduction, airlock, and cavitation are explored. In the second chapter, methods of measuring aeration are analyzed and compared. The beaker, coriolis, evacuation, radionuclide, optical, impedance, and capacitance methods are also compared. In the third and final chapter, methods of air introduction are described. Suction port T-fitting, direct injection and limitations on aeration rate are discussed. This white paper will help you better understand aeration, measurement, and control.
