MSS Type Spring Floor Mounted Seismic
The MSS Type Spring Floor Mounted Seismic System is a heavy-duty vibration isolation and seismic protection system designed for industrial equipment.
It is not only used for controlling mechanical vibration during normal operation, but also helps reduce destructive force transmission between equipment and building structures during earthquakes or external impacts, thereby ensuring safe and stable equipment operation.
What Problems Can the MSS Type System Solve in Industrial Vibration and Seismic Protection?
- Designed for heavy industrial machinery vibration and seismic protection
- Low natural frequency for effective vibration isolation
- High load-bearing capacity suitable for large equipment
- Reduces both vertical and horizontal vibration transmission
- Improves equipment stability and operational accuracy
- Provides structural protection under seismic conditions
- Long service life with stable performance
- Adjustable installation height for easy leveling
How Does the MSS Type Spring Seismic System Work for Vibration and Earthquake Protection?
The MSS Type system works based on low-frequency vibration isolation principles.
By using high-performance steel springs, the system reduces the overall natural frequency of the support structure, effectively separating machine vibration from the building foundation.
This allows the system to:
Reduce resonance amplification effects
Absorb and distribute vibration energy
Minimize vibration transmission to the floor structure
Improve overall machine stability
During seismic events, the spring system also absorbs sudden shock energy, reducing structural damage risk.
Which Industrial Equipment Can Use the MSS Type Spring Seismic System?
The MSS Type Spring Floor Mounted Seismic System is widely used in:
Rice milling machines
Rotary sifters and screening equipment
Generators and power systems
Air compressors and HVAC systems
Industrial fans and blowers
Heavy processing machinery
Precision industrial production equipment
Case Study: Netherlands Rice Milling Machine Vibration Issue
1. Project Background
A rice processing facility in the Netherlands was experiencing severe vibration issues with its milling equipment, which affected both operational stability and surrounding structure safety. The excessive vibration not only reduced processing efficiency but also raised concerns about long-term equipment reliability.
The client approached us seeking a customized vibration isolation solution.
2. Equipment Information
- Machine Model: Satake ST1037R-T1
- Motor Power: 2.2 kW (4P, 50 Hz)
- Operating Speed: 200 rpm
- Machine Weight: 1850 kg
- Loaded Weight: 2200 kg
3. Problem Analysis
Rice milling machines operate with rotating and impact forces, which can easily generate:
- Horizontal shaking (forward-backward & left-right movement)
- Low-frequency structural vibration
- Equipment displacement during operation
In this case, the vibration was particularly severe due to:
- Relatively low operating speed (200 rpm → low-frequency vibration)
- Heavy dynamic load (2200 kg total weight)
- Lack of effective lateral constraint
Traditional rubber pads or standard spring isolators were not sufficient to control both vertical vibration and horizontal displacement.
4. Our Solution
We provided a custom-designed MSS Type Spring Floor Mounted Seismic Vibration Isolator, specifically engineered for this application.
Key Features:
- Heavy-duty spring isolation system
Effectively absorbs low-frequency vibration generated by the machine - Built-in seismic lateral restraint (limit structure)
Prevents excessive horizontal movement and ensures operational stability - Customized load design
Each isolator is calibrated based on the actual working load (2200 kg) - Robust floor-mounted structure
Ensures secure installation and long-term durability
5. Technical Advantages
Compared with conventional solutions, the MSS isolator offers:
Dual Protection System
Combines vibration isolation + displacement control in one unit
Excellent Low-Frequency Performance
Spring system is ideal for 200 rpm equipment, where rubber solutions fail
Enhanced Safety
Seismic limit design prevents machine tipping or excessive movement
Long Service Life
All components are designed for heavy industrial use with stable performance
6. Installation Optimization
To further enhance system stability, the isolator design includes:
- Integrated limit bolts / guide structure
- Controlled clearance for safe movement range
- Even load distribution across all mounting points
This ensures the machine operates smoothly without resonance or structural stress concentration.
7. Final Results
After installation of the MSS Type isolators:
- Machine vibration was significantly reduced
- Horizontal shaking was effectively eliminated
- Equipment stability improved noticeably
- Noise level decreased
- Overall production efficiency increased
The client expressed high satisfaction with the performance and reliability of the solution.
8. Conclusion
For heavy industrial equipment like rice milling machines, especially under low-speed and high-load conditions, standard vibration isolators are often insufficient.
Our MSS Type Spring Floor Mounted Seismic Isolator provides a comprehensive solution by combining:
- Vibration reduction
- Structural stability
- Safety control
We specialize in customized vibration isolation solutions for various industrial applications.
