Common failures of unit operation

In the daily use of diesel engine generator sets, some common failures directly affect the service life and production efficiency of diesel engine. So it is very important to understand the fault of diesel engine. Below, we introduce the common fault of diesel engine and fault reason analysis.

Common failures of unit operation

Diesel engine power decrease or the engine smoke

1. Air filter is too dirty (clean or change )

2. Compressor outlet and exhaust pipe joint leakage (tighten the clip or fasteners)

3. Turbine inlet and exhaust pipe joint leakage (replace the gasket and tighten the fasteners)

4. Engine intake pipe leakage (replace the gasket and tighten the fasteners)

5. Exhaust pipe rupture or gasket damage replace the gasket and tighten the fasteners

6. Diesel engine compressor impeller contamination (clean)

7. Supercharger of diesel set are damage(repair or change)

8. Diesel engine fuel system is out of order

Diesel engine compressor seal leakage

1. Diesel engine air filter too dirty (Clean or exchange)

2. Diesel engine compressor suction port blocked or contamination (Remove dirt)

3. The supercharger return pipe (Clean or replace)

4. Pressurized gas intermediate shell lubricants coking and sludge(Clean or replace the supercharger)

5. Engine piston ring and cylinder liner wear

6. Diesel engine damage of pressurized gas (repair or replacement)

Diesel engine turbine side seal leakage

 

1. The supercharger return pipe (Clean or replace)

2. The supercharger intermediate shell lubricating coking and sludge (Clean or replace the supercharger)

3. Engine piston ring and cylinder liner wear repair or replacement)

4. The supercharger is damaged (Repair or replace the supercharger)

Diesel engine abnormal sound

 

1. Compressor suction duct obstruction leads to compressor surge

2. Contamination of compressor impeller, causing the compressor surge

3. Air intake system leak and abnormal noise generation

4. Venting system leakage and abnormal noise generation

5. Rotor scratches shell

6. Diesel engine turbocharger damage (repair or replace the supercharger)

Diesel engine machine oil consumption rise

 

1. Poor supercharger return pipe road (remove dirt)

2. The turbine end sealing ring damage (send turbocharger repair station to repair)

3. Diesel engine compressor side sealing ring damage(Send the supercharger depot repair)

4. Turbocharger shell accumulate a large amount of sludge in the middle (Send the supercharger depot repair)

5. The supercharger damage (repair or replace the supercharger)

6. Diesel engine oil brand is not in conformity with the requirements replace the right oil)
