There are three types of failure in a fluid power system. 1. Degradation. The performance of the component degrades over time as surfaces wear, clearances increase, and leakage increases. 2. Intermittent. Valves stick and then break loose such that operation is intermittent. 3. Catastrophic. Catastrophic failure occurs when a major component breaks apart. Often, debris …

Hydraulic Contamination Sources
There are four sources of contamination in hydraulic fluid. 1. Built-in contamination. This is contaminate that was left in the system when it was assembled. It can range from a piece of teflon tape to a piece of welding slag. 2. Contaminated new oil. Contaminate is introduced during the manufacture and subsequent handling of oil. …
