Introduce the principle of a hydraulic damper

Oil Hydraulic Damper is a 1970s developed speed responsive damping device, which by means of special structures valve control cylinder piston moves to curb piping or equipment periodic load and shock load affected. Holid pneumatic component is mainly used to prevent damage to piping or equipment due to the earthquake, water hammer, steam hammer, wind load, exhaust valve and other impact loads caused. Working process of hydraulic damper can be "hardness and softness" to describe, in the normal thermal expansion of piping or equipment can move slowly along, at which time almost no damping force, then the performance of the "soft"; hydraulic damping during load transients the valve is activated, this time with the vibration force which produces the reverse resistance of the same size, a greater throttling piping or equipment vibrations, reduce the amplitude, which play a role in the protection of pipes or equipment, then the performance of the "Gang .
