Product Description

Hydraulic damper is a damping device that uses special valve control to control the movement of the hydraulic cylinder piston to suppress the impact of periodic loads or impact loads on pipelines and equipment. Its performance characteristics can be summarized in four words: "hardness and softness": when the pipeline is in normal working condition, it can adapt to the slow movement of the pipeline caused by changes in the cold and heat of the medium and produce almost no damping on the pipeline, which is the so-called " "Soft"; under special accident conditions (such as earthquakes, water hammer, steam hammer, safety valve exhaust, broken pipes, etc.), when the pipeline is subject to an instant impact, the hydraulic damper becomes a nearly rigid mechanism to support the pipeline, and the impact load is Vibration energy can be quickly absorbed and transmitted, thereby reducing the impact amplitude of the pipeline and achieving buffering and earthquake resistance requirements.

Application Scope

 

Due to its excellent vibration reduction performance, hydraulic dampers are widely used in the vibration resistance of pipelines, important equipment and main load-bearing beams (supports) in nuclear power, thermal power, petrochemical, steel, wind energy, solar energy and other industries; they can effectively protect pipelines , equipment, main load-bearing beams (supports), etc. are protected from damage by accidental impact loads.
Common working conditions that produce occasional impact loads include:
Inside the system: water hammer, steam hammer, safety valve exhaust, main steam valve quick closing, boiler explosion, broken pipe, etc.
Outside the system: earthquakes, wind loads, impacts from foreign flying objects, etc.
 

Product Features

 

1. The displacement indication is clear and clear;
2. Simple appearance, symmetrical and compact structure, convenient installation and small installation space;
3. The friction resistance is small, generally lower than 1%-2% of the rated load;
4. Large damping force and small dynamic response time;
5. Both ends of the damper are equipped with spherical bearings, allowing a swing angle of ±6° during operation;
6. The damping valve with special structure has high working reliability;
7. The hydraulic medium uses stable, flame-resistant silicone oil, and the seals use rubber materials with good tolerance to various environments.
