Oil Hydraulic Lock, also known as hydraulic lock or hydrolock, is a condition that occurs when a fluid, such as oil or water, fills a cylinder or chamber in an engine or other mechanical system, preventing the movement of the piston or other moving parts. This can occur when the engine or system is flooded with fluid, such as during a failed attempt to start a flooded engine or due to a leak in the system. Hydraulic lock can cause serious damage to the engine or system, including bent connecting rods, broken pistons, and damaged valves. It is important to address any signs of hydraulic lock immediately to avoid costly repairs.
The working principle of hydraulic locks is very simple, which is to control the pressure of the system by adding safety valves. When the system pressure reaches a predetermined value, the safety valve will open to release excessive hydraulic flow, thereby avoiding system damage or danger. Hydraulic lock is an active protective device that can effectively protect the safety of the system and personnel.
