How does a hydraulic lock work?
Hydraulic Locks in Action Hydraulic locks can hold the gate at any position by stopping at any position along the actuator’s stroke when power is switched off or lost. It can then move in either direction—gate open or closed—when power is restored. This ensures safety is retained and property damage prevented.
Why do many hydraulic applications require the cylinder to be locked?
Rod locking cylinders are an important component for ensuring safety in the case of compressed air supply failure. For static applications, they can activate to provide emergency holding strength during a power outage or disconnection in air supply.
Does hydrolock happen immediately?
Hydrolocking can also occur when the engine is not running. It’s the case with flood cars, for example. The only damage you’re likely to encounter in this scenario is in the event the fluid isn’t removed quickly, and the engine’s insides corrode.
Is used for locking hydraulic cylinders in position?
Bear-Loc is a locking device that can be used in systems that require infinite position locking, zero backlash, and high stiffness. The Bear-Loc can be supplied with a hydraulic cylinder or used with existing cylinders. …
What is a lockout valve on a hydraulic cylinder used for?
A hydraulic lockout valve is used in pneumatic and hydraulic applications to prevent injury during maintenance to machinery.
How do you remove an airlock?
The first way to clear an airlock, involves attaching a hose pipe to the hot and cold taps at a sink. Then, turn the cold tap on so that the water flows through the hose pipe and into the hot water tap. This flow of cold water into the hot water tap should clear the airlock.
What causes cylinder failure?
Piston and rod damage can occur due to normal wear and tear, however, damage from rod bearings or pistons are a common cause of cylinder failure. Bending or side loading due to improper installation can add unneeded force to your cylinder, ultimately causing complete system failure.
How does a hydraulic rod lock device work?
This fit provides a positive mechanical connection to lock the rod in any phase of the stroke. As soon as hydraulic pressure is applied the sleeve expands radially within the elastic limits, relieving the interference and creating enough clearance for the rod to be stroked with minimal resistance.
Why do you need a hydraulic cylinder lock?
The spareness of the design is a defining characteristic of this revolutionary hydraulic cylinder safety stop, with failsafe lockout as just one of its capabilities. Because the locking does not depend on moving parts to function, you’ll enjoy the benefit of smooth, efficient operation, regardless of locking position or configuration.
How does hydraulic pressure work on a bear Loc?
As soon as hydraulic pressure is applied the sleeve expands radially within the elastic limits, relieving the interference and creating enough clearance for the rod to be stroked with minimal resistance. Simply removing the hydraulic pressure via the unlock port allows the BEAR-LOC® to re-engage automatically.
How often should you flush a bear Loc lock?
Answer: We recommend periodic flushing of the lock with hydraulic fluid to remove any contaminants that have been deposited by hydraulic fluid flow during operation. Flushing fluid through the two Bear-Loc® ports is adequate to provide this flushing maintenance and keep the lock functioning properly.
