Which of the following percentages reflects hydraulic systems that fail due to contamination?

The statement that approximately 70% of hydraulic system failures are attributed to contamination is well-supported by industry studies and maintenance insights. Contamination in hydraulic systems can manifest through dirt, particulate matter, water, or other foreign substances, which can significantly impair the functionality and longevity of hydraulic components.

This level of failure percentage is coherent with what reliability engineers observe in practice. Contaminants can cause various issues such as wear and tear on components, reduced efficiency, increased operational temperature, and ultimately lead to system failure. Maintaining cleanliness and implementing proper filtration can mitigate these risks. Hence, understanding the impact of contamination on hydraulic system reliability is vital for engineers focused on maintaining and improving asset integrity.
