In a hydraulic system, how does removing air from fluid lines affect performance?

Removing air from fluid lines in a hydraulic system significantly improves responsiveness because air is compressible, while hydraulic fluid is not. When air is present in the lines, it creates a situation where the hydraulic system has to work harder to transmit force. The presence of air can lead to a spongy feel in the system, resulting in delayed responses when controls are actuated.

By purging air from the fluid lines, the hydraulic fluid can flow more freely, and the system can maintain consistent pressure throughout. This direct pathway for fluid movement allows for quicker response times to changes in control inputs, making the system more effective in its operations. Overall, a system free of air improves control, precision, and efficiency in hydraulic applications.
