How can the low-speed and heavy-duty design of Marine Diesel Generators comprehensively improve operating performance?

In Marine Diesel Generators, various moving parts such as pistons, connecting rods, crankshafts, bearings, etc. will generate greater friction and wear when running at high speeds. Low-speed operation can significantly reduce the relative motion speed between these components, thereby reducing friction and wear. This not only extends the life of the equipment but also reduces heat and noise caused by friction. Low-speed operation also helps reduce the amount of lubricating oil used and the frequency of replacement, because the reduction in friction means that the consumption of lubricating oil will also be reduced accordingly.
High-speed rotating components will produce greater mechanical noise, such as bearing rotation, gear meshing, piston knocking, etc. These noises not only affect the operator's comfort, but may also cause interference to the surrounding environment and equipment. Low-speed operation can significantly reduce the generation of these noises, making the entire generator set run quieter. Low-speed operation also helps reduce secondary noise caused by vibration, such as pipe vibration, structural resonance, etc.
High-speed rotating components are prone to resonance when exposed to external excitation, resulting in increased vibration. Vibration will not only affect the stability and reliability of the generator set, but may also cause damage to surrounding equipment and structures. Low-speed operation can reduce the occurrence of this resonance phenomenon, thereby reducing the vibration level. The reduction in vibration also helps improve the accuracy and performance of the generator set, as vibration can interfere with the accuracy of measurement and control systems.
The heavy-duty design gives the entire generator set greater mass and inertia, making it better resistant to external disturbances and vibrations. This helps maintain stable operation of the generator set and reduces noise and mechanical failures caused by vibration. The heavy-duty design also helps to improve the overturning resistance of the generator set, especially when used on mobile platforms such as ships, ensuring the stable operation of the generator set in harsh conditions such as wind and waves.
Heavy-duty design reduces vibration by optimizing vibration transfer paths. For example, by adding shock-absorbing devices (such as rubber shock absorbers, spring shock absorbers, etc.) to absorb and disperse vibration energy; by changing the connection methods of components (such as using flexible connections, floating supports, etc.) to reduce vibration transmission; by optimizing Structural layout to avoid the occurrence of resonance points, etc. These measures not only reduce vibration levels but also increase the reliability and durability of the generator set.
Heavy-duty design usually means thicker siding, larger section sizes and stronger joints. These designs not only improve the load-bearing capacity of the generator set, but also enhance its resistance to fatigue and impact. The enhanced structural strength helps reduce structural damage and deformation caused by vibration and impact, thereby extending the service life of the equipment.
The combination of low-speed operation and heavy-duty design can produce significant vibration and noise reduction effects. This design not only improves the reliability and durability of the generator set, but also makes it more environmentally friendly and user-friendly in practical applications. This design is important for applications such as ships that require long-term, continuous operation.
