The reason for the deformation of Cummins diesel generator set is firstly the defects in the casting process, secondly, the deformation of the body during the welding crack due to high temperature, and thirdly, the maintenance personnel according to the technical requirements when disassembling or assembling the cylinder head. Around deformation: fourth, when the thickness is not uniform during the casting, the main body will be deformed or the residual stress of the workpiece is too large.
Because the crack will cause the Cummins diesel generator unit to leak into the oil pan or oil leakage, the diesel engine will not work properly. If the body is deformed, the relative position of the surface of the parts of the machine will be destroyed and the concentricity of the holes of the box will break the main bearing. The degree of parallelism between the center line and the vertical center line of the main bearing of the box and the hole and the camshaft of the center line of the main bearing of the box.
Cracks in the main body of Cummins diesel generating units are usually caused by inadequate maintenance performed by the operator. For example, in cold areas, the refrigerant is forgotten to be released from the diesel engine, and the excessive buildup of scale leads to local heat dissipation. Diesel engine runs for a long time under high load, making the internal thermal stress too large. The operator suddenly experienced high temperatures in the diesel engine. When cold water is added to the tank, the body is affected by a large external force.
