Equipment Instructions

Hydraulic dampers can be widely used in various industries such as nuclear power, thermal power, steel, and petrochemicals. Hydraulic dampers can protect objects such as pipeline systems, main pumps, important valves, important pressure vessels, steam turbines, and long beams.

Advantages of hydraulic dampers

During the thermal expansion process of pipelines, hydraulic dampers allow for free thermal displacement of pipelines without generating additional stress.

● Large load range (up to 600kN maximum); Long work schedule (up to 500mm maximum)

● High damping force, fast and reliable action. Especially suitable for low-frequency and large amplitude working environments.

Will not resonate with pipelines or equipment.

● Adapt to various working environments: above room temperature, below room temperature, high humidity, high salinity, dust, nuclear radiation, and other environments.

Bidirectional hydraulic dampers (also commonly known as hydraulic buffers or bidirectional damping cylinders), from the perspective of their appearance with double earring connections, all metal sealing structure, and multi-stage damping design, belong to industrial heavy-duty buffering actuators. Their core performance features focus on bidirectional buffering, energy absorption, and motion stability, as follows:

1、 Core job performance

Bidirectional symmetrical damping, no impact during start stop operation

Built in bidirectional throttling and buffering valve core, the piston rod can generate stable damping force in both directions of extension and retraction, completely solving the problem of "one-way effectiveness and reverse unconstrained" of ordinary one-way buffers. It can accurately control the starting and braking process of equipment moving parts, avoiding rigid impact.

Adjustable damping force, suitable for multiple working conditions

The adjusting screw plug (golden knob) on the top of the cylinder body can directly adjust the opening of the internal throttle hole, achieving stepless adjustment of damping force/motion speed. It can flexibly match the best buffering effect according to changes in load weight and motion speed, without the need to replace components.

Multi level buffering design, high energy absorption efficiency

The multi-stage stepped structure on the cylinder body is a graded damping section, which can achieve a "fast first, slow second" stepped buffering during the motion process, greatly improving the energy absorption capacity and suitable for kinetic energy dissipation under high-speed and heavy load conditions (such as large Hydraulic Press sliders and heavy-duty transfer mechanisms in automated production lines).

2、 Structure and durability performance

High strength all metal structure with strong load resistance

The cylinder body and piston rod are made of integral forged alloy steel, and the surface is chrome plated and hardened, with high hardness and good wear resistance; The double earring connection method can withstand large radial loads and swinging moments, and is suitable for complex stress scenarios in industrial equipment.

High sealing reliability and long maintenance cycle

Adopting industrial grade heavy-duty combination seals, combined with the dust-proof and leak proof structure of the cylinder body, can effectively resist the erosion of harsh industrial environments such as dust and oil stains. The hydraulic oil leakage rate is extremely low, reducing frequent oil replenishment and maintenance work.

Compact size, good installation adaptability

Integrated cylindrical design, small size and light weight. The standardized connection method of the double earrings can be directly installed through a pin shaft, without the need for complex fixed brackets, and can flexibly adapt to the narrow installation space of various hydraulic presses and automation equipment.

3、 Exclusive advantages for applicable scenarios

Specially designed for heavy industrial equipment, it is particularly suitable as a slider buffer and balance auxiliary component for hydraulic presses (four column, frame type, Wheel Hub Hydraulic Presses) that you have previously focused on. It can also be used for motion stability of metallurgical and mining equipment. The core advantage is that it can improve the stability of the host operation, protect the mold, and extend the service life of the equipment.
