1.Invention Patents 2.Stainless steel casing 3.Design based on customer needs
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
