缸套——活塞环是内燃机中主要配对摩擦付之一,也是工作条件最为恶劣、磨损最严重的摩擦付,它往往最容易导致内燃机出现故障。为了保证内燃机能长期而可靠地运转,我们必须严格控制缸套和活塞环的材料机械性能、金相组织、表面处理、尺寸公差、形位公差、表面粗糙度和外观质量……等,这些项目都可以通过产品的单项检验予以考核。但是,这些项目完全合乎技术要求的产品是否能确保内燃机长期而可靠地运转,这还需要经过专项试验和装机试验予以考核。
Cylinder liner - piston ring is one of the main matching friction in the internal combustion engine, but also the worst working conditions, wear the most serious friction, it is often the most likely to cause internal combustion engine failure. In order to ensure the long-term and reliable operation of the internal combustion engine, we must strictly control the mechanical properties of the material of the liner and the piston ring, the microstructure, the surface treatment, the dimensional tolerances, the form tolerances, the surface roughness and the appearance quality ...... Can be tested through the product of a single test. However, whether these projects fully meet the technical requirements of products to ensure that long-term and reliable operation of internal combustion engines, which also need to go through a special test and installed capacity test to be assessed.
