Maintenance Methods for Diesel Generator Sets

Diesel generator sets, as emergency or backup power sources, have been widely used in various fields. During use, due to various reasons, the units may inevitably encounter various faults. In this case, it is necessary to investigate and repair the units. When carrying out unit maintenance work, attention should be paid to using the correct process and methods, following the correct operating procedures, in order to ensure the quality and efficiency of diesel generator set maintenance work and ensure human-machine safety.

The organizational methods for the maintenance process of diesel generator sets can be divided into two types: the basic methods of generator set maintenance operations and the forms of labor organization.

1. Basic methods for repair work

For the repair of generator sets, the basic methods can be divided into on-site repair method and assembly exchange repair method.

(1) Machine repair method

In the process of repairing a generator set, the method of repairing any repairable parts, components, assemblies, etc. that have been removed from the original machine, except for scrapped parts, and still being installed back into the original machine after repair, is called on-site repair method. At present, most units adopt this repair method.

When using the on-site repair method, due to the varying degrees of damage to each part, assembly, or assembly, the amount of repair work and the required repair time also differ, which often affects the continuity of repair and assembly work. The assembly of the entire machine often requires waiting for the parts, assemblies, or components with the longest repair time to be repaired before proceeding, resulting in a longer repair time. But for general units, there are not many models of the same type, and in situations where accessories are scarce, using this repair method is advantageous.

(2) Assembly exchange repair method

During the repair process of the generator set, except for the engine body, all other assemblies, assemblies, and parts that need to be repaired are replaced with reserve parts (repaired or newly purchased), and the replaced assemblies, assemblies, and parts are stored in the reserve warehouse as spare parts after repair. This repair method is called assembly exchange repair method. This repair method reduces the time delay caused by repairing assemblies, components, and parts, ensures the continuity of repair work, greatly shortens repair time, and improves production efficiency. It is suitable for units with a large number of the same model and sufficient spare parts reserves.

2. The labor organization form of maintenance work

(1) Comprehensive homework method

The comprehensive operation method refers to the repair operation of the entire generator set, except for individual parts repair and processing (such as forging, mechanical processing, etc.) which are completed by professional workshops or professional work groups, all other work is completed by one work group. With this operation method, the work scope of the work group is relatively wide (understanding both internal combustion engine repair technology and motor repair technology), and the technical requirements for the staff are relatively comprehensive. Currently, most units adopt this method.

(2) Professional division of labor method

The professional division of labor method refers to dividing the unit repair operation into several work units according to job types, parts, assemblies, components or processes, with each unit being undertaken by one worker or one work group. This method of operation is easy to improve the technical proficiency of workers in individual operations, facilitate the use of professional tools, and achieve high-quality repair goals. However, it requires the technical management department to have a complete and sound management method to ensure that the repair work is carried out rhythmically.
