Causes of Difficulty in Maintenance of Cummins Generator

Due to the relatively rough operation of Cummins generator, high noise, slight burning of cylinder gasket, which is difficult to detect and judge, the cylinder gasket was not replaced in time or repeatedly burned, resulting in deformation of cylinder liner of Cummins generator, damage of sealing water blocking ring, and impact of high-temperature and high-pressure gas on lintel between cylinder head and cylinder block, resulting in serious erosion grooves of Cummins generator. As a result, the maintenance of Cummins generators is difficult and the scrapping of parts is common.

Especially for imported engines with high compression ratio and high turbocharging, it is more prominent, seriously affecting the economic and reliability of construction machinery. The difference between the upper plane of the cylinder liner of Cummins generator and the upper plane of the cylinder block, as well as the height difference between the cylinder liners under the same cylinder head must meet the specified requirements. If it is not suitable, it should be adjusted with shims between the shoulder of the cylinder liner of Cummins generator and the cylinder block seat. During the press fitting of cylinder liner of Cummins generator, special tools shall be used for press fitting, and the force shall be uniform. It is strictly prohibited to hit and knock on the surface of cylinder liner of Cummins generator to prevent local deformation of cylinder opening of Cummins generator.

The cylinder gasket quality and the correct assembly method will directly affect its service reliability and life. So the selected cylinder gasket must be of the same specification and thickness as the original cylinder, with a flat surface, firm edge bonding, and no scratches, dents, wrinkles, or rust. Since the crimping side of the cylinder gasket of the Cummins generator has a projection, the plane connecting with it will cause indentation deformation of the Cummins generator. Generally, when the cylinder head and cylinder block of Cummins generator are made of cast iron, the crimping faces the cylinder head. If the cylinder head is made of aluminum alloy and the cylinder block is made of cast iron, the rolled edges should face the cylinder block.
