Prevent Misoperations and Extend the Lifespan of Your Generator Set

Prevent Misoperations and Extend the Lifespan of Your Generator Set

Improper use of diesel generator sets during operation can significantly affect their service life. Here, we’ll explain in detail the common misoperations to avoid in daily use:

1. Forcing the Engine to Operate When Oil Supply Is Insufficient

Operating the engine with inadequate oil supply causes insufficient lubrication on friction surfaces, leading to abnormal wear or damage.

2. Stopping the Engine Under Load or Immediately After Removing the Load

When a diesel generator set is stopped under load or suddenly after load removal, the cooling system stops circulating water, drastically reducing its heat dissipation ability. Heat-affected components lose cooling, which can lead to:

• Cracks in the cylinder head, cylinder liner, or cylinder block.
• Excessive piston expansion, causing it to seize in the cylinder liner.

3. Running Under Load Without Warm-Up After a Cold Start

Starting a diesel generator in cold conditions without a warm-up leads to:

• Insufficient oil supply due to high viscosity and poor flow of oil.
• Poor lubrication on friction surfaces, causing severe wear and damage such as cylinder scoring or bearing failures.

4. Operating with Insufficient Cooling Water and High Oil Temperature

Insufficient cooling water reduces the cooling effect, causing the diesel engine to overheat. High oil and water temperatures exacerbate this, leading to:

• Overheating of the cylinder head, cylinder liner, piston assembly, and valves.
• A significant decrease in mechanical properties like strength and toughness.
• Increased deformation and reduced clearance between components, accelerating wear.
• In severe cases, cracks, seizure, or component failures.

Avoid these mistakes to ensure the longevity and efficient performance of your diesel generator set!
