What does "bleed" refer to in a technical process?

"Bleed" in a technical process specifically refers to the act of removing air or fluids from a system, particularly in hydraulic or pneumatic systems. This process is essential for ensuring proper functionality and performance, as trapped air or fluid can create inefficiencies, cause erratic behavior, or lead to system failure. For example, in hydraulic systems, bleeding helps to eliminate air bubbles that can compress, resulting in reduced pressure and unreliable operation. Similarly, in fluid systems, bleeding ensures that the system runs efficiently without any obstructions or airlocks. Understanding this term is crucial for maintaining and troubleshooting a variety of mechanical and engineering applications, where precision and reliability are paramount.
