A mechanical snubber is a mechanical device designed to protect components from excess shock or sway caused by seismic disturbances or other transient forces. [1] During normal operating conditions, the snubber allows for movement in tension and compression. [2] When an impulse event occurs, the snubber becomes activated and acts as a restraint ...
Snubbers allow for free thermal movement of a component during regular conditions, but restrain the component in irregular conditions. [6] A hydraulic snubber allows for pipe deflection under normal operating conditions. When subjected to an impulse load, the snubber becomes activated and acts as a restraint in order to restrict pipe movement. [7]
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
The Babinet–Soleil compensator is a continuously variable, zero-order retarder consists of two birefringent wedges, one of which is movable, and another is fixed to a compensator plate. The orientation of the long axis of the wedges is perpendicular to the long axis of the compensator plate. Schematic view of a Babinet–Soleil compensator
Motion compensators are usually placed between a floating object and a more stationary object, such as a vessel or a structure fixed to the seabed. Most general motion compensators will compensate for movement in all directions The simplest motion compensator is the anchor chain of a ship. Not only does the anchor prevent the ship from drifting ...
Compensator can refer to: Pressure control on a piston pump; An alternative term for pipeline expansion joints; A muzzle brake, used to counter the recoil of a firearm, or to prevent the muzzle from climbing due to kickback from the rapid firing of an automatic or semi-automatic weapon; A device that offsets or counterbalances a destabilising ...
225k Snubbing Unit 340k units are designed to perform live and dead well interventions on both land & offshore.. Snubbing is a type of heavy well intervention performed on oil and gas wells.
The main principle in PHC is to store the energy from the external forces influencing the system and dissipate them or reapply them later.Shock absorbers or drill string compensators are simple forms of PHC, so simple that they are normally named heave compensators, while "passive" is used about more sophisticated hydraulic or mechanical systems.
