What is the cause of the piston ring damage fault in the diesel generator set? Only by identifying the cause can the fault be eliminated. Huaquan Power introduces that the piston ring damage fault of diesel generator sets is related to abnormal piston or connecting rod, abrasion, and incorrect installation of piston rings during assembly!
1. Abnormal piston or connecting rod of the generator, causing abnormal wear of the piston ring. Excessive clearance between cylinders and deformation of connecting rods caused by piston wear can lead to abnormal wear of piston rings.
2. The difference in hardness between the generator piston ring and the cylinder wall is too large, that is, the material of the piston ring does not match the cylinder wall.
3. Diesel generator set combustion products, engine oil deterioration, and abrasion caused by various abrasives. Engine oil is the engine oil of diesel generator sets. When the engine oil enters the combustion chamber, it forms black carbon deposits. When the air filter is not working properly, the air entering the cylinder will gather dust and metal debris generated by wear, which will cause abrasive wear.
4. When assembling, install the piston ring backwards or incorrectly; Improper opening clearance can cause the piston ring to break; The ring mouth is not evenly distributed, and there is excessive light leakage between the piston ring and the cylinder wall, with too many areas of light leakage, resulting in a decrease in cylinder pressure.
5. When the generator set is in use, there is insufficient cooling water, and the temperature of the diesel generator set is too high, which significantly reduces the function of the piston ring. At this point, the piston rings, pistons, and cylinders will all be damaged.
The above is an introduction to the causes of piston ring damage in diesel generator sets, hoping to provide assistance to users.
