1. What Is a Hydraulic Buffer?
A hydraulic buffer is a high-performance device designed to absorb and dissipate extreme impact energy in industrial machinery. SHUYI’s hydraulic buffers use hydraulic oil and piston systems to decelerate heavy moving parts (e.g., press brakes, large robots), providing superior protection in high-energy scenarios compared to mechanical buffers.

2. How Hydraulic Buffers Work
SHUYI’s hydraulic buffer operates through three stages to manage intense 冲击力:
- Impact Engagement:
A piston connected to the moving part pushes into the buffer cylinder, forcing hydraulic oil through precision orifices. This creates resistance that slows down the motion. - Energy Dissipation:
The oil’s viscosity converts kinetic energy into heat, while a pressure relief valve prevents overload by releasing excess pressure during extreme impacts. - Smooth Recovery:
A return spring pushes the piston back to its original position, ready for the next impact, with minimal rebound.
3. Hydraulic Buffer vs. Mechanical Buffer: Key Differences
| Feature | Hydraulic Buffer | Mechanical Buffer |
|---|---|---|
| Energy Capacity | Handles high-energy impacts (500J–10,000J+) | Suitable for low-to-medium impacts (≤500J) |
| Deceleration Control | Smooth, adjustable deceleration via orifice size | Faster but less controllable deceleration |
| Maintenance | Requires periodic oil checks and replacement | Low maintenance; no fluid-related upkeep |
| Temperature Range | Operates in 0°C–60°C (ideal for moderate climates) | Resistant to -40°C–+80°C for harsh environments |
| Cost | Higher initial cost, long-term reliability | Lower cost, suitable for budget applications |
4. Core Advantages of SHUYI’s Hydraulic Buffers
SHUYI’s hydraulic buffers stand out for heavy-duty industrial applications:
- High-Impact Resistance:
Absorb up to 10,000J of energy per impact, protecting presses, cranes, and automated storage systems from destructive shocks. - Precision Deceleration:
Adjustable orifice plates allow fine-tuning of deceleration curves, ensuring smooth stops for precision machinery like elevator guides or robotic arms. - Durable Design:
Stainless steel pistons and 密封件 resist corrosion and wear, with a service life of over 500,000 cycles in continuous operation.
5. When to Choose a Hydraulic Buffer
SHUYI’s hydraulic buffer is the ideal solution for:
- Heavy Machinery:
Press brakes, metal stamping machines, and large industrial robots that generate over 1,000J of impact energy during operation. - Precision Applications:
Systems requiring controlled deceleration, such as airport baggage handling conveyors or CNC machine tool changers, where sudden stops could affect accuracy. - Medium-Temperature Environments:
Operations in factories, warehouses, or outdoor settings with temperatures between 0°C and 60°C, where hydraulic oil maintains optimal viscosity.
6. When Mechanical Buffers Make Sense
Mechanical buffers are better suited for:
- Low-to-Medium Impact Loads:
Conveyor belts, packaging equipment, or small robotic arms with impact energy below 500J, where simplicity and cost-effectiveness are priorities. - Extreme Temperature Settings:
Environments exceeding 60°C or below 0°C (e.g., cold storage, foundries), where hydraulic oil may thicken or thin, affecting performance.
7. How to Select the Right Buffer
Consider these factors when choosing between hydraulic and mechanical buffers:
- Impact Energy Rating:
Match the buffer’s energy capacity to your machine’s needs (e.g., 5,000J for hydraulic, 300J for mechanical) to avoid underperformance or overspending. - Deceleration Requirements:
Opt for hydraulic buffers if you need adjustable, smooth stops; choose mechanical buffers for fast, basic impact absorption. - Environmental Conditions:
Use hydraulic buffers in moderate climates and mechanical buffers in extreme temperatures or dry, dusty environments.
