Reasons for Deformation of Diesel Generator Body

Deformation of diesel generator sets can be caused by casting defects, welding cracks, high-temperature deformation, improper disassembly/assembly of cylinder heads or screw holes by maintenance personnel, uneven casting thickness, or excessive residual stress.

Cracks resulting from deformation can lead to leaks: lubricating oil in the oil pan may mix with water or leak out, preventing the diesel engine from operating normally. Additionally, diesel engine deformation disrupts the relative positions of mechanical part surfaces, including the concentricity of main bearing bores, the parallelism between main bearing bores and camshaft bearing bore centerlines, and the perpendicularity between cylinder centerlines and main bearing bore centerlines.

Common causes of deformation due to operator error or poor maintenance include:

1.Forgetting to drain coolant in cold regions during storage;

2.Excessive scale buildup causing localized poor heat dissipation;

3.Prolonged high-load operation leading to excessive internal thermal stress;

4.Sudden addition of cold water to the radiator when the engine is overheated;

5.Severe external impact on the engine block.

To better use and maintain generator sets, users should familiarize themselves with relevant professional knowledge.

How to accurately detect diesel engine block deformation? Dingbo Power, a generator manufacturer, recommends the following methods:

1.Check the height difference between the two ends of the engine block using a vernier caliper or height gauge to assess the parallelism of the upper and lower planes. To check the parallelism between the main bearing bore and the engine block bottom surface, the block must be flipped.

2.Measure the deformation of the upper and lower planes using a straightedge and measuring tools.

3.Test the concentricity of valve seat bores inside the block with an internal micrometer.
