Products Description
A hydraulic lock is a control element in a hydraulic system that is primarily used to lock the hydraulic circuit under specific conditions, preventing the flow of fluid to ensure that an actuator (e.g., cylinder) in the system remains in a specific position.
Hydraulic lock is an important safety component in the hydraulic system, the correct selection and use of hydraulic lock is essential to ensure the safe, stable and reliable operation of the system.
Working Principle
A hydraulic lock usually consists of two hydraulically controlled check valves that can be interlocked to allow the cylinder to remain stationary in the absence of an external control signal.
When the system pressure is higher than the set value, the hydraulic lock opens, allowing the oil to flow and the actuator to move.
When the system pressure is lower than the set value or there is no control signal, the hydraulic lock closes, preventing the flow of oil and keeping the actuator stationary.
Application
Construction machinery: such as excavators, cranes, etc., used to keep the arm or hook in a specific position.
Lifting platforms: used to keep the platform in a stable position when it is not working.
Hydraulic systems: In applications where cylinders need to be prevented from falling due to gravity, such as hydraulic support systems.
Safety equipment: In equipment where accidental movement needs to be prevented, such as safety gates, guard rails, etc.
