What is the technical breakthrough in the Piston Ring industry?
The future of several years is China's industrialization, urbanization, shopping and internationalization of the pace of accelerating the strategy to develop opportunities, but also China's comprehensive construction of a moderately prosperous society in the critical period. With the further deepening of the reform of the socialist market system, China's Piston Ring shopping malls will be fully open. Modern diesel engines are more broad in terms of improving their functionality - increasing power output, reducing fuel consumption, reducing heat loss and reducing environmental pollution. To this end, many diesel component manufacturers are also forced to start improving their production of components to improve the overall function of diesel engines. Piston Ring production is not an exception, they use new information, improve the old production process.
The domestic Pistons ring enterprises in the development of skills is still there is still a certain gap between foreign countries, in the data and appearance processing, the domestic enterprises are basically no innovation; in the product platform verification, the domestic enterprises have just started; domestic enterprises lack of product design experience , In recent years began to pile up a variety of data; domestic technology level affected by the larger equipment, messy products is difficult to ensure production capacity. Domestic Pistons new skills are still in the exploratory stage, although the skills themselves are now sophisticated, but the use of the Piston Ring also need to do a lot of research, testing. A variety of new skills have their own advantages and disadvantages, the key to solve the quality problems. The domestic Piston Ring enterprises rely on the introduction of foreign skills to improve their own skill level.
In recent years, the Piston Ring structure changes little, the researchers mainly in the information and technology to explore. Such as the Piston Ring surface coating process, although the chemical chrome approach has always been a dominant position, but a variety of physical spraying new skills are gradually being used. In addition, the Piston Ring career also learn the relevant professional skills to improve the level of technology, such as conflict face processing skills. Piston Ring technology has two trends: First, steel ring. At that time, the first ring of gasoline engine is now completely selected steel materials, diesel engine use of steel ring is also a high share. Second, the Piston Ring height becomes smaller. After the Piston Ring height becomes smaller, the seal between the Piston Ring and the cylinder is strengthened, reducing the chance of oil entering the combustion chamber, which can reduce the emission pollution.
The main function of the gas ring is to seal and heat transfer. To ensure that the piston and the cylinder wall between the seal to prevent the combustible mixture within the cylinder and high temperature gas leaked into the crankcase, and the top of the piston to accept the heat transfer to the cylinder wall, to prevent the piston overheating. The main function of the oil ring is to scrape off the excess oil to the cylinder wall, and in the cylinder wall coated with a layer of uniform oil film. Piston Ring work by the cylinder in the high temperature, high pressure gas role, and in poor lubrication under the conditions of high speed sliding in the cylinder. Due to the cylinder wall shape error, so that the Piston Ring in the upper and lower sliding at the same time also radial movement in the ring groove. This not only increases the wear of the ring and the ring groove, but also the Piston Ring by the role of alternating bending stress and easy to break.
Piston Ring material and surface treatment. According to the function and working conditions of the Piston Ring, the material of the Piston Ring should have good wear resistance, thermal conductivity, heat resistance, impact toughness, elasticity and sufficient mechanical strength. Currently widely used Piston Ring materials are high-quality gray cast iron, ductile iron, alloy cast iron and steel and so on.
