Brief Introduction to Kedias Damper
Polyurethane damper for hydraulic Hammers, is used specially for sound damper/absorber for hydraulic hammers. Within working process of Hydraulic Breaker (Hammer), there is high vibration oscillation inside of machine. To dampen vibration, the Upper and Side Polyurethane Dampers are in binding use. They are used as the damper/buffer inserts between the metal parts of rock breaker/hammer to absorb the vibration/shock/sound.
What are Features of Polyurethane Damper for Hydraulic Breaker?
Abrasion Resistance
The abrasion resistance of polyurethane dampers for hydraulic breakers is a crucial factor in determining their durability and longevity in harsh working conditions. The abrasion resistance of polyurethane (PU) dampers for hydraulic breakers is typically quite high. PU is known for its durability and resistance to wear, making it a suitable material for dampers in hydraulic systems.
Cut and Tear Resistance
The cut resistance of a polyurethane damper refers to its ability to resist being punctured or sliced by sharp objects or debris that may be present in the working environment. A high level of cut resistance ensures that the damper maintains its integrity and continues to function effectively, even in the presence of potential cutting hazards. Tear resistance, on the other hand, refers to the ability of the polyurethane material to resist tearing or splitting when subjected to tensile forces or impact. A damper with good tear resistance can better withstand the stresses and strains caused by the rapid movements and impacts of the hydraulic breaker, reducing the likelihood of premature failure.
Excellent Dynamic Properties
One key dynamic property of polyurethane dampers is their ability to rapidly respond to and dissipate impact energy. This quick response time helps to minimize the transmission of shock and vibration to the surrounding structures, protecting them from damage and extending their lifespan. Additionally, polyurethane dampers exhibit good elasticity and resilience, allowing them to recover quickly after being compressed or deformed. This rapid recovery helps to maintain stable damping performance over time, even under repeated impacts and vibrations.
Impact Resistance
Impact resistance refers to the ability of a material to withstand and absorb the force of a sudden, intense blow or impact without significant damage or deformation. Polyurethane dampers are designed to effectively dissipate the energy generated by impacts, reducing the transmission of shock and vibration to the surrounding structures. Polyurethane dampers exhibit good elasticity and resilience, which allow them to rapidly recover from deformations caused by impacts. This quick recovery maintains the damper's shape and function, enabling it to continue absorbing impacts effectively over time.
Low Compression Set
The low compression set of polyurethane dampers for hydraulic breakers is a crucial property that ensures their long-term performance and reliability. Compression set refers to the permanent deformation that occurs in a material after it has been compressed and then released. Polyurethane dampers with a low compression set maintain their original shape and performance even after repeated compression cycles, making them suitable for applications that require consistent damping over time.
Low Temperature Resistance
Many polyurethane remain flexible at very low temperatures and possess outstanding resistance to thermal shock. The low temperature resistance of polyurethanes has led to many applications in Arctic conditions.
Automotive
PU dampers are used in vehicle suspension systems to absorb shocks and vibrations, improving ride comfort and stability.
Construction
In hydraulic breakers, PU dampers are crucial components for absorbing impact forces and reducing vibrations during operation, enhancing efficiency and longevity.
Industrial Machinery
PU dampers are employed in industrial machinery to dampen vibrations, minimize noise, and protect sensitive components from damage.
Aerospace

Inspect Regularly
Regularly inspect the PU damper for signs of wear, damage, or deterioration. Look for cracks, tears, or deformation that may affect its functionality. Address any issues promptly to prevent further damage.
Cleanliness
Keep the damper and its surrounding area clean to prevent the accumulation of dirt, debris, or contaminants that could interfere with its performance. Regularly remove any buildup that may affect the damper's movement or sealing.
Avoid Excessive Heat
Protect the PU damper from excessive heat sources, as high temperatures can affect its material properties and performance. Ensure that the damper is not exposed to direct sunlight or placed near heat-emitting equipment.
Avoid Chemical Exposure
PU dampers may be susceptible to certain chemicals, oils, or solvents. Avoid contact with substances that can degrade or damage the damper material. Refer to the manufacturer's recommendations for chemical compatibility.
Replace Damaged Dampers
If a PU damper shows signs of significant wear, damage, or loss of functionality, it should be replaced promptly. Continuing to use a damaged damper can compromise the performance of the system and potentially lead to safety hazards.
