Dismantling Principles and Technical Requirements for Diesel Generator Sets

When a serious malfunction occurs in a diesel generator set, it is necessary to disassemble and repair the entire unit. In order to prevent component damage or even damage to the entire unit, Dingbo Electric reminds you that maintenance personnel must operate only after mastering the technical requirements for disassembly and assembly. This is also a prerequisite for diesel generator set maintenance. At the same time, a detailed maintenance plan should be developed to carry out the disassembly and assembly of the diesel generator set in a planned and organized manner. Those that should not be disassembled must not be disassembled, and the disassembly scope should be minimized as much as possible.

Principles and technical requirements for dismantling diesel generator sets

To prevent various unexpected situations and ensure the smooth progress of disassembly work, users should follow the following principles during disassembly:

1. Understand and master the structure and principles of diesel generator sets and their various components;

2. When disassembling, repair and assembly should be considered. For units without technical data and instructions, it is necessary to keep detailed records of the torque of the disassembled components, such as fuel injection advance angle, valve clearance, torque for unscrewing connecting rod screws, torque for disassembling cover screws, and the relative position of each component before disassembly, for assembly and troubleshooting;

3. Do not arbitrarily expand the scope of repair;

4. Follow the prescribed disassembly principles.

The disassembly of diesel generator sets is not difficult, but there are generally certain requirements for disassembling cylinder head screws, such as:

1. The disassembly of double headed screws can be carried out using double nuts, and generally does not require disassembly;

2. The disassembly of rusted nuts can be carried out by tightening first and then loosening, or by uniformly heating the nuts with a spray;

3. The disassembly of interference fit parts is generally carried out using specialized tools;

4. Marking and labeling are important tasks. Disassembled components such as fuel injectors, connecting rods, push rods, lifters, rocker arms, intake and exhaust valves, valve springs, etc. should be labeled to indicate the cylinder number. The relative positions of various components should also indicate the cylinder number, as the wear of each cylinder varies during the operation of diesel generator sets.

The above are the principles and technical requirements for disassembling diesel generator sets introduced by Dingbo Power. Whether it is conducting three-level maintenance of the unit or troubleshooting one or several faults, users must follow the above principles and technical requirements. Before repairing, they must have a comprehensive understanding of the fault symptoms, technical conditions, and usage of the unit, and prepare all necessary tools before starting the disassembly work.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
