Our company independently developed and produced JZN series viscous damper .Each performance index of the product reaches technological level of congeneric products home and abroad.
1.Principle formula:
F=C×Va,
F:Damping force(kN)
C:Damping coefficient(kN/(mm/s))
V:Velocity of piston(mm/s)
a:velocity exponent,designed and selected according to the engineering requirements,value is generally taken between 0.2~1.when a=1,it is linear damping.
A selected range of velocity exponent a is 0.1~1,damper giving priority to earthquake resistance commonly selects a<0.4;damper to wind resistance selects a≥0.4.
2.Capacity of corporate testing machine:
Maximal stroke: ±500mm
Maximal dynamic load speed: 1200mm/s
Maximal dynamic force: 3000kN
Highest frequency: 5Hz(±10mm)
Test waveforms: sine,triangle,square wave
3.Features
1) The special structure of the snubber valve
2) The lugs with ball bushing
3) Ease of installation
Fluid viscous damper to protect structures
