Preparation for Dismantling and Repairing Diesel Generator Sets

In recent years, the application of diesel generator sets has continued to soar, and users have encountered more questions in making contingency plans and actual use. When a diesel generator set malfunctions, it is necessary to disassemble the entire unit to eliminate the problem. However, the unit should not be disassembled blindly. Dingbo Electric reminds you that the following preparations should be made before starting disassembly.

Preparation

1. Fully understand the technical condition of the diesel generator to be repaired

Before disassembling and repairing, users should have a comprehensive understanding of the fault symptoms, technical conditions, and usage of the diesel generator set. For example, if the diesel generator burns oil, it should be determined which cylinder or all of it is faulty, and the faulty part should be identified before repairing and disassembling.

2. Preparation of technical data and maintenance site

Before repairing a certain type of diesel engine, it is necessary to understand the instructions and technical requirements for repairing the unit. The repair technical standards for different types of diesel generators are different. In addition, a certain amount of space should be prepared when disassembling, and disassembly should not be carried out outdoors in strong winds or rainy days.

3. Preparation of maintenance tools

Common tools: open-end wrench, ring wrench, pliers, socket wrench, adjustable wrench, torque wrench, hammer, wooden hammer, steel saw bar, etc;

Special tools: sockets for disassembling connecting rod screws, tools for assembling pistons, etc.

Measuring tools: feeler gauges, steel rulers, etc. used to adjust valve clearances, must be able to use inner and outer micrometers used for disassembling piston rings.

Lifting tools: jacks, pry bars, pulleys, etc.

Equipment preparation: oil drums, square plates for washing items, brushes, sandpaper, labels and personal protective equipment for recording each cylinder component.

In order to ensure the smooth progress of dismantling work, prevent casualties, damage to tools and equipment, deformation, corrosion, and rework errors, the specific rules are as follows:

1. Use tools appropriately

When disassembling, it is necessary to use specialized tools for diesel generators, and generally do not use adjustable wrenches. When tightening and disassembling screws, the torque should be appropriate, and extension rods should generally not be used to prevent bolt breakage. When disassembling, apply even force to prevent component damage caused by excessive force.

2. Prevent accidents and injuries

Do not forcefully disassemble components that cannot be removed. It is important to understand the specific structure of the component and not expand the scope of disassembly arbitrarily. The scope of disassembly should be determined based on the repair content and project. If possible, do not disassemble as much as possible. The disassembled components should be placed in an orderly manner and not haphazardly together. Parts that cannot be repaired for a long time should be treated with rust prevention. The disassembled precision parts should be placed in pairs.

After completing the above disassembly preparations, the user can proceed with the disassembly operation of the diesel generator set. Although the models of diesel generator sets are different and the disassembly steps and methods are not completely the same, the basic requirements are the same. After mastering the technical requirements for disassembly and assembly, the user can proceed with the operation. If you have any questions, please feel free to call Dingbo Power.
