Yaw oil damper for railway :
In the working process, damper was converting the system vibration energy into heat energy scattering in the air so as to achieve the effect of vibration reduction.
Technical characteristics:
this structure is variable damping and passive damper(PSHD), it is new type passive damper with the semi-active control performance by adjusting the sequence of control walve.
the drawing damping force and conpressing damping force of product is essentially equal, and the damping characteristics is symmetrical
damping performance is adjustable through scientifically and reasonably controlling walve 1, walve 2, walve 3 to get the different damping characteristics damper.
the dampers has the charactersics of overload unloading, automatic protection.
the dampers has reliable performance, convenient maintenance, competitive price performance.
series of damper:
| series | max. damping force(KN) | max. outer diameter(mm) |
| 40 | 10 | 82 |
| 50 | 15 | 102 |
| 60 | 25 | 120 |
Type:
1. primary vertical damper(axle box damper)
