The four supporting accessories of diesel generator set include: cylinder liner, piston, piston ring and piston pin.
1. Cylinder liner. Cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. The cylinder liner that does not contact the cooling water on the back is called a dry cylinder liner, and the cylinder liner that is in contact with the cooling water on the back is a wet cylinder liner.
The two important indicators of the cylinder liner are the hardness of the cylinder liner, which mainly reflects the wear resistance, corrosion resistance and processability of the cylinder liner; The second is the material, which mainly considers the mechanical strength of the cylinder liner.
The original dry cylinder liner of Carter imported diesel engine is made of specially treated hardened steel, which has high hardness, good wear resistance, good corrosion resistance and small expansion coefficient, which can ensure a long service life.
Second, pistons. The piston is one of the most important components of the diesel generator set, which is mainly composed of aluminum alloy material with a layer of metal plating on the surface to improve wear resistance.
The original piston of the imported diesel engine is made of aluminum alloy, which has good thermal conductivity and low thermal expansion coefficient, which can effectively reduce the possibility of detonation, and can effectively reduce the weight of the piston, reduce the inertia of reciprocating motion, and increase the engine speed.
3. Piston rings.
The piston ring is one of the important moving parts in the diesel generator set, which is mainly used to prevent gas leakage in the cylinder and ensure the sealing between the piston and the cylinder wall.
The original piston ring of Carter imported diesel engine is made of alloy cast iron material, and the surface is chrome-plated to improve wear resistance and anti-seizure, and the structural design is reasonable and effectively reduces the wear of the piston.
Fourth, piston pins.
The piston pin is an important part connecting the piston and the connecting rod in the diesel generator set, which mainly bears the gas pressure and reciprocating inertia force.
The original piston pin of Carter imported diesel engine is made of alloy steel material, and the surface is carburized to improve wear resistance and fatigue strength, and the combined structure is adopted for easy replacement.
In short, the four supporting parts of the original diesel engine imported by Carter have excellent wear resistance and corrosion resistance, which can effectively improve the service life of the engine; At the same time, advanced materials and processes are used to ensure engine performance and reliability. When purchasing and using, please be sure to choose the original parts from regular channels to ensure the normal operation and safety of the engine.
