Four Major Repair Methods for Diesel Generator Components

Whether it is a domestic diesel generator set, an imported Volvo diesel generator set, or other brands, after long-term operation, the moving parts will wear out due to friction, gradually changing the original size of the parts. Therefore, it is necessary to repair them in order not to affect the normal operation of the diesel generator set.

There are many methods for repairing parts of diesel generator sets, and corresponding repair methods can be selected based on the characteristics of part defects and repair cost accounting. Common methods for repairing parts include mechanical processing repair, pressure processing repair, welding repair, and adhesive repair.

(1) Mechanical processing repair method: The repair method that restores the correct geometric shape and fitting characteristics of worn parts through mechanical processing is called mechanical processing repair method. The commonly used methods are repair size method and sleeve repair method. The repair dimension method is a repair method that involves increasing or decreasing the repair dimension of worn parts in a mating pair according to regulations, and then selecting another part with the same repair dimension to restore the mating properties of the mating pair. The sleeve repair method is a repair method that involves machining and shaping the worn parts of a component, and then inserting a metal sleeve through interference fit to restore the basic dimensions of the component.

(2) Pressure processing repair method

The repair method of restoring the size and shape of the damaged part by applying external force to the part and utilizing the plastic deformation of the material is called pressure processing repair method.

(3) Welding repair method

The repair method of using the heat generated by arc or gas combustion to melt and fuse the damaged parts and welding rods locally, in order to fill the worn parts or connect the broken parts, is called welding repair method.

(4) Adhesive repair method

The repair method of using adhesive to repair or connect broken parts is called adhesive repair method.

Wear and tear parts of equipment should be repaired as much as possible while ensuring equipment accuracy, avoiding replacement. This not only ensures the normal functioning and performance of mechanical equipment, but also reduces maintenance workload and repair costs. Many repair processes require the configuration of corresponding process equipment and certain technical personnel, and involve the entire maintenance organization management and maintenance production schedule. Therefore, when choosing a repair process, please consult a professional diesel generator company.
