The inner surface of the cylinder is prone to wear due to the action of high-temperature and high-pressure gas and contact with the high-speed moving piston. There are different cylinder structures and surface treatment methods to improve the wear resistance of the cylinder and extend its service life. There are three types of cylinder structures: non cylinder liner type, dry cylinder liner type, and wet cylinder liner type.
The cylinder sleeveless body refers to the body without any cylinder sleeves embedded, and the cylinder is directly processed on the body. The advantage is that it can shorten the center distance of the cylinder, reduce the size and quality of the body. But the cost is higher.
The dry cylinder liner is not in contact with the coolant and has a wall thickness of 2-3mm. The outer surface and the inner surface of the cylinder liner seat hole must be precision machined to ensure necessary positional accuracy and facilitate disassembly and assembly. The advantages are high body stiffness, small cylinder center distance, light weight, and simple processing technology. The disadvantages are poor heat transfer, uneven temperature distribution and local deformation. |
