Products Description
Hydraulic lock is used in engineering machinery, lifting machinery outrigger circuit and press self-locking and mining underground bracket wall jack locking and other hydraulic systems, in order to make the working organism in any position after stopping, not subject to the influence of the external load and tampering, so the use of hydraulic locks to form a locking system.
A hydraulic lock is a valve used in hydraulic systems whose primary function is to lock the position of a hydraulic cylinder or other hydraulic actuator to prevent movement in the event of an interruption in system pressure or power source. Hydraulic locks ensure that the actuator remains stable in any position, even in the absence of a control signal, preventing unintended movement due to gravity or external loads. Below are some of the key features and working principles of hydraulic locks:
Principle of operation
Hydraulic locks typically consist of a valve body, one or more spools, springs and seals. When system pressure is applied to the spool, the spool is pushed to open or close the oil circuit, thereby controlling the locking or releasing of the hydraulic cylinder.
Type:
Unidirectional Hydraulic Lock: locks the hydraulic cylinder in one direction only, usually used to prevent lowering due to gravity. Bi-directional hydraulic lock: locks the hydraulic cylinder in both directions and is used where stability is required in any position.
Function:
Position locking: In the event of a loss of power in the hydraulic system, the hydraulic lock lock locks the position of the actuator. Safety protection: in case of emergency, the hydraulic lock can be used as a safety device to prevent dangerous movement of the actuator due to malfunction. Areas of application:
Hoisting machinery: used to lock the position of lifting weights to prevent accidental lowering. Hydraulic lifts: to keep the lift car stable in case of power failure or other faults. Construction machinery: in excavators, cranes and other equipment, used to lock the position of the actuator.
Features
Reliability: Hydraulic locks are designed to be simple and reliable, capable of locking the position of actuators at critical moments.
Easy to integrate: Hydraulic locks can be integrated into existing hydraulic systems without the need for complex control logic.
Easy maintenance: maintenance of hydraulic locks is relatively simple and mainly involves checking seals and cleaning valve bodies.
Working Pressure and Flow: Select a hydraulic lock that can withstand the working pressure and flow of the system.
Direction of locking: Select the appropriate hydraulic lock based on the direction of locking required (unidirectional or bidirectional).
Environmental conditions: Consider the environment in which the hydraulic lock will be used, such as temperature, humidity, and media to which it may be exposed. Maintenance:
Periodically check the sealing performance of the hydraulic lock to ensure that there are no leaks. Clean the valve body and spool to prevent impurities and contaminants from affecting the performance of the valve. Check springs and other internal parts for wear and replace as necessary. Hydraulic lock is an important safety component in the hydraulic system, which provides a reliable locking function through simple mechanical means to ensure the safety and stability of the system under various working conditions.
