Improvement of productivity in hydraulic systems with servomechanisms

© 2019 The Authors. Published by Elsevier B.V.This work presents the design of a chemical process used to clean the internal surface of carbon steel pipelines used in hydraulic systems that have servomechanisms and meet class 3 NAS purities. This purity class requires a maximum pollution particle count of 160, 40, and 5 particles of pollution per cubic centimeter of solution with a size of 2, 5, and 15 micrometers, respectively, as pollutants greater than 10 micrometers impede the operation of servomechanisms. Current processes were designed under the assumption that pollutants found in the hydraulic oils were caused by system erosion, rather than from the incorrect execution of chemical cleanliness. This false assumption has prevented improvements to the chemical process, as a high pollution content is the most common cause of failure of any lubricated mechanical component. The proposed process will allow the pollution to be diminished. This reduction will help generate more production and fewer costs in the functioning of carbon steel pipelines of hydraulic systems with directional, proportional and servo valves.
