Riguid viscous damper for engineering structures

1.Design based on customer needs 2.Stainless steel casing 3.Factory price

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 damper valve

 

2) The use of hydraulic fluid

 

3) Ease of installation
