Introduction of L28/32 Diesel Engine Parts Function and Working Conditions of Cylinder Liner
① Composition of the combustion chamber
②The four-stroke machine is the guide of the piston movement and bears the side thrust
③The two-stroke engine cooperates with the piston movement to control the ventilation process
④ It forms a cooling water space with the cylinder block
2. Working conditions
①Withstand periodic changes in gas force:
Radial: The compressive stress of the fire contact surface is Z, and the cooling surface is zero.
Tangential: The tensile stress of the fire contact surface is large, and the tensile stress of the cooling surface is small.
②The effect of bearing thermal load: compression thermal stress on the fire contact surface and tensile thermal stress on the cooling surface.
③ withstand friction
④The inner surface is subjected to chemical corrosion by gas, and the outer surface is subjected to corrosion by cooling water.
⑤The cylindrical piston is subjected to the cavitation of cooling water.
Made of heat-resistant and wear-resistant alloy cast iron, the inner surface is chrome-plated to improve wear resistance, and the outer surface is coated with anti-rust paint or zinc blocks.
4. Types of marine diesel engine accessories:
①Good heat dissipation
②The thickness of the cylinder liner is large and the rigidity is good
③Easy to manufacture and replace
④ prone to cavitation and corrosion.
