What does 'hydraulic lock' refer to?

Hydraulic lock refers to a condition where the hydraulic system becomes immobilized due to trapped fluid within the system. This situation occurs when hydraulic fluid cannot flow freely due to a blockage, valve closure, or other constraints, resulting in the inability of the system to perform its intended functions.

In a hydraulic system, fluid is essential for the transmission of force and movement, so when there is an accumulation of fluid that cannot circulate, the system may experience a halt in operation. This immobilization can be detrimental, especially in applications where precise movements and operations are critical. Recognizing hydraulic lock is important for troubleshooting and ensuring that the system can be restored to normal working conditions. Understanding this concept is vital for maintaining hydraulic systems effectively and preventing operational failures.
