Product Characteristics
Basis Information
The service life of piston rings will gradually wear out with the increase of engine working time, so regular inspection and maintenance are required. If severe wear, fracture, or deformation of the piston ring is found, it should be replaced in a timely manner to ensure the normal operation of the engine.
Product Process
Strict quality control is also required during the manufacturing process of piston rings. This includes quality inspection of raw materials, precision inspection of molds, control of the casting process, and inspection of the size, hardness, and structure of the rings after processing and heat treatment.
The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
