The three internal causes of obstacles in diesel generator sets are expected to lead to the attention of the people: the structural characteristics of the components, and the various components of the unit have their own characteristics in the structural mode. In labor, external factors often act through these characteristics, causing obstacles in associated machinery. For example, due to the structural characteristics of the engine water jacket itself, under the action of high temperature, the cooling water simply forms scale on the outer wall of the cylinder liner, which affects the cooling effect of the cylinder liner.
The labor characteristics of the parts, the direct contact and the relative movement of the parts caused by the conflict. For example, the piston ring of the diesel engine directly touches the cylinder. During the labor process, the piston ring performs high-speed reciprocating linear motion in the cylinder, causing the cylinder to wear. Parts with strong temperature changes during labor, deformation and cracks due to thermal stress. For example, during engine labor, the cylinder block and the cylinder head are subjected to high temperature, and the internal stress is distributed from the head to reach a new average, which results in warpage deformation of the cylinder block and the cylinder head plane.
In the design and manufacture process, the nature of raw materials and oil materials should be accurately selected according to the labor nature and characteristics of the generator set parts. The raw materials are not properly selected, the materials are not suitable for the regulations, and the improper substitutes are used to cause wear, erosion, deformation, and The main points of fatigue, damage, division and aging. The essence of the various raw materials and oil used in the unit is nothing more than the physical essence, the chemical essence and the nature of the machine.
Many obstacles to the crew are due to the influence of external factors and the consequences of these essences. If the metal material is too strong, it will deform and crack and even break. It will oxidize under high temperature and will cause fatigue damage under various loads. Non-metallic materials will cause aging, and the acid materials contained in the oil will erode the metal. Function, and will make the oil deteriorate.
