Adverse Effects of Piston Ring Damage in Diesel Generator Sets

Damage to the piston ring of diesel generator sets is common, and it may occur after two or three years of machine operation. This involves replacing the piston ring with a new one, and the diesel generator set can be restored to normal use. So, if you see that the function of the piston ring is quite wrong, because the elastic openings on both sides of the piston ring are damaged, causing the cylinder to seal and causing oil gas channeling, which affects the power and fuel economy of the diesel generator set.

In addition, one side of the ring may wear and affect the cylinder seal. Therefore, piston rings play an important role in the operation of diesel generator sets.

The piston or connecting rod of the diesel generator set is abnormal, causing abnormal wear of the piston ring. Piston wear leads to excessive cylinder clearance, and deformation of the connecting rod can cause abnormal wear of the piston rings. The stiffness of the piston ring in diesel generator sets is significantly different from the cylinder wall, that is, the material of the piston ring is incompatible with the cylinder wall.

Diesel generator set combustion products, oil degradation, and wear of various abrasives. Oil is the engine oil of a diesel engine, which enters the combustion chamber to form black carbon deposits. When a poor air filter is in operation, the air entering the cylinder with ash will converge, wear metal particles, and cause abrasive wear.

During assembly, the piston ring will be loaded and an error will occur. Incorrect opening can cause the piston ring to break. Unreasonable distribution of the annulus, light leakage from the piston rings and cylinder walls, excessive leakage area, decreased cylinder pressure, insufficient cooling water during use, excessively high temperature of the diesel generator set, and significantly reduced piston ring function. At this point, the piston ring, piston, and cylinder are all damaged.
