7 Ways to Extend the Life of Your Diesel Generator Set with Resistoflex Mounting Systems

Every diesel generator propagates vibrations when it runs. These vibrations, if not controlled, can propagate into the foundation and damage nearby equipment, loosen bolts, and even crack the floor.

• Technical Aspect : Anti-vibration mounts (AVMs) are designed with elastomeric materials like rubber or neoprene, which absorb and reduce vibrations.
• Benefit : By minimizing vibration transfer, the generator’s internal components—such as the bearings, alternator, and fuel system—last longer, resulting in reduced maintenance
• Simply put, controlled or less vibration = more generator life.

For larger industrial diesel generators, we use Spring Mounts. In such cases, spring mounts play a crucial role.

• Technical Aspect : Spring mounts allow vertical and lateral deflection, which makes them perfect for handling low-frequency vibrations typically produced by big diesel engines.
• Benefit : They provide stability to the generator and prevent resonance conditions, which otherwise could lead to premature wear and tear.

Spring mounts also reduce noise transmission, making them a good choice for hospitals and office buildings.

A solid base frame is the foundation of a diesel generator’s mounting system

• Technical Aspect : Base frames are usually made of steel or fabricated structures that are designed to distribute the generator’s weight evenly across the mounting system
• Benefit : A good base frame prevents misalignment, reduces excessive load on mounts, and ensures smooth performance

Without a strong base, even the best mounts won’t function effectively.

Every mounting system is designed to bear a specific load range. If the load is unevenly distributed, the mounts can fail prematurely.

• Technical Aspect : Mounts have load ratings (measured in kilograms or newtons) that must match the weight and vibration frequency of the generator.
• Benefit : Proper load distribution avoids over-compression of mounts, leading to longer life of both the generator and the mounting system.

Always check the rated load capacity before choosing mounts for your generator.

Diesel generators are often criticized for being noisy. Noise doesn’t just disturb the surroundings but also indicates vibration-related inefficiencies

• Technical Aspect : Acoustic mounts and relevant isolators use a combination of rubber and spring technology to reduce both structure-borne and airborne noise
• Benefit : Reduced noise = better working environment + longer machine life (as noise often means energy loss through vibration).

This is especially useful in places like schools, residential complexes, and offices.

Just like the generator, the mounting system itself also requires regular checks.

• What to Check:
  • Cracks in rubber mounts
  • Rust or corrosion on spring mounts
  • Signs of over-compression or sagging
• Benefit : Detecting problems early avoids costly breakdowns and keeps the generator stable for years

A quarterly inspection routine is usually enough for most industrial setups

Not every generator setup is the same. Some require tailor-made mounting systems to handle specific challenges like high seismic activity, offshore platforms, or continuous heavy load operations

• Technical Aspect : Customized mounts are designed with higher deflection, reinforced steel, or specialized elastomers for extreme conditions.
• Benefit : Ensures reliability and safety even in demanding environments, preventing structural failures and extending generator life
Additional Tips for Extending Generator Life

Along with mounting systems, here are some extra measures that can enhance your diesel generator’s lifespan :

• Regular servicing (oil change, filter cleaning, coolant check).
• Proper ventilation to avoid overheating.
• Load management to prevent overloading
• Fuel quality check to avoid deposits and blockages.

When combined with the right mounting systems, these practices can easily add several years to your diesel generator’s life.

Conclusion

Diesel generators are a long-term investment, and protecting them is crucial for cost savings and reliability. While routine maintenance is important, mounting systems play a hidden yet powerful role in extending the generator’s lifespan. From reducing vibrations with AV Mounts to ensuring stability with spring mounts and custom solutions, the right mounting system can make all the difference.

By following these 7 proven ways, and by choosing reliable isolation solutions from Resisitoflex, businesses and individuals can ensure their diesel generators perform efficiently, quietly, and long lasting.

Frequently Asked Questions

Q1: How can I reduce vibration in a diesel generator?

You can reduce vibration in a diesel generator by installing anti-vibration mounts or spring mounts under the machine. These mounts absorb the vibrations created by the engine and prevent them from transferring to the floor or nearby equipment. Along with mounts, using a strong base frame and regular alignment checks also helps in keeping vibration levels low.

Q2: What is the best mounting system for diesel generators?

The best mounting system depends on the size and usage of your diesel generator:

• For small to medium generators, rubber anti-vibration mounts work best.
• For large industrial gensets, spring mounts or spring + rubber combination mounts are more effective.
• If noise control is also a concern, acoustic mounts are the most suitable choice

Q3: Do anti-vibration mounts increase generator life?

Yes, absolutely. Anti-vibration mounts protect the generator’s internal parts like bearings, alternator, and fuel system from constant vibration stress. By minimizing wear and tear, they reduce the chances of mechanical failure and extend the overall life of the generator. In simple words, less vibration = longer lifespan + fewer repairs.

Q4: How do spring mounts help in generators??

Spring mounts are designed to handle low-frequency, heavy vibrations produced by large diesel generators. They allow controlled vertical and lateral movement, which prevents cracks, misalignment, and structural damage. Another benefit is that spring mounts also reduce noise transmission, making the generator run smoother and quieter.

Q5: How to maintain diesel generator mounts?

Maintaining generator mounts is simple but very important. Here’s what you should check regularly

• Look for cracks or wear in rubber mounts.
• Inspect spring mountsM for rust, corrosion, or sagging
• Make sure the generator’s load is evenly distributed on all mounts.
• A quarterly inspection is usually enough for most setups.
