Hydraulic Snubbers Damping Device / Shock Absorber For Pipe
Hydraulic Snubbers are restraining devices used to control the
movement of pipe and equipment during abnormal dynamic conditions
such as earthquakes, turbine trips, safety/relief valve discharge
and rapid valve closure. The design of a snubber allows free
thermal movement of a component during normal operation conditions,
but restrains the component in abnormal conditions.
HOW DOES A HYDRAULIC SNUBBER / SHOCK ABSORBER WORK ?
The basic working principal behind a hydraulic snubber is that
under slow (normal) speeds, a piston moves within a hydraulic
reservoir pushing hydraulic fluid from the front to the back (or
visa versa) of that reservoir. When an impulse load occurs and the
piston tries to move at a high speed, a valve will close thereby
restricting or blocking the movement of the fluid within the
reservoir and subsequently locking the moving piston.
WHERE IS HYDRAULIC SNUBBER / SHOCK ABSORBER APPLIABLE FOR?
The hydraulic snubber is widely used for resisting vibration of
pipeline system and other equipments to nuclear power projects,
thermal power projects, wind power project, solar power project,
petrochemical projects, military industry, steel industry, and etc
industries due to its excellent damping performance. And it can
effectively protect the pipeline system and equipments from damage
of shock load.
The common application situations are as followed:
A, The shock damage which from inside system of pipeline and
Water Hammer; Steam Hammer;
Steam venting by the safety valve;
The sudden shutdown of the main air valve;
Explosion of the boiler;
Breaking of pipeline
B, The shock damage which from outside system of pipeline and
Accidental Shock from outside
The hydraulic snubber can effectively protect the pipeline system,
important pumps, important valves, important pressure vessels,
steam turbines, main support beams and so on.
