Key Hydraulic Damper Features

Temperature Resistance: Designed to operate efficiently across a wide temperature range.

Corrosion Resistance: Available in materials and finishes suitable for corrosive environments.

Compact Design: Engineered for space-efficient integration into your equipment.

Silent Operation: Smooth, quiet performance for noise-sensitive applications.

Low Maintenance: Sealed units require minimal maintenance, reducing ongoing costs.

Application areas

Construction and bridge engineering: Oil dampers are used to reduce the vibration of buildings or bridges under earthquake or strong wind conditions and improve the seismic resistance of the structure.

Mechanical equipment: Used to absorb the vibration and impact generated during the operation of mechanical equipment and extend the service life of the equipment.

Vehicle suspension system: Similar to shock absorbers, oil dampers are used to reduce the vibration caused by uneven roads during driving and improve driving comfort.

Industrial equipment: Used to slow down the braking process of sports equipment and prevent equipment from being damaged by impact force.

Types of Hydraulic Shock Absorbers

Twin-Tube Shock Absorbers
- These consist of two cylinders: an inner cylinder where the piston moves and an outer cylinder that acts as a reservoir for the hydraulic fluid. They are common in passenger vehicles due to their balance of performance and cost.

Mono-Tube Shock Absorbers
- In these, the piston moves in a single tube. They are generally more efficient at heat dissipation and provide better performance, making them popular in high-performance and off-road vehicles.

Adjustable Shock Absorbers
- These allow the damping characteristics to be manually adjusted, providing flexibility for different driving conditions and preferences. They are often used in racing and high-performance applications.

FAQ

Q: What is the principle of damper?

A: In simple terms, damping is the ability of any object to dissipate energy. One of the most common models that we use to represent damping is viscous damping, in which the damping force is directly proportional to the velocity of the damper.

Q: What is a damper and its types?

A: The primary damper types include control, balancing, backdraft, multizone, industrial, and safety dampers. Control dampers: These are installed at various ductwork junctures to regulate airflow throughout the HVAC system. They can also help mix hot and cold air to attain the ideal temperature zone for occupants.

Q: What does the damper control?

A: An HVAC damper is a small valve or metal plate that regulates the airflow inside a building's heating, ventilation, and air conditioning (HVAC) system.

Q: How can i get the price?

A: We usually quote within 24 hours after we get your inquiry(Except weekend and holidays). If you are very urgent to get the price, please email us or contact us in other ways so that we can offer you a quote.

Q: Can I buy samples placing orders?

A: Yes.Please feel free to contact us.

Q: What is your lead time?

A: It depends on the order quantity and the season you place the order. Usually we can ship within 7-15 days for small quantity,and about 30 days for large quantity.

Q: What is your payment term?

A: T/T,Western Union,Alipay,MoneyGram,and Paypal.This is negotiable.

Q: Do you provide technology support?

A: YES. Our company have design and development team, we can provide technology support if you need.

Q: How do hydraulic shock dampers reduce press fatigue?

A: Without adequate control, snap through shock issues cause press fatigue by imposing compounding reverse load pressure on the press structure. Press fatigue cracks occur in the drive linkage, slide, crown, bed and housings. The most vulnerable parts, such as hydraulic lines and bolts, are affected first, and damage continues in a progressive manner. Even the most durably built presses are susceptible to press fatigue from negative tonnage issues. Hydraulic shock dampers absorb the forces generated during press operation so that the press structures are no longer subject to the affects.

Q: How do I determine if my hydraulic dampers will require a cooling system?

A: Removing heat build up in the hydraulic oil is critical in some blanking applications. The risks associated with excessive heat can be alleviated by installing dampers with a cooling system.
