一活塞环的作用及使用要求活塞环是压缩机上的主要件(图1),当压缩机运行时,活塞环在气缸壁与活塞之间起着密封及刮除气缸壁上多余润滑油的作用。因此要求活塞环的外圆柱面能够全部地紧密的靠在气缸壁上,压缩气体达到规定的压力。活塞环质量的好坏,直接影响压缩机工作, The role of a piston ring and the use of the piston ring is the compressor on the main pieces (Figure 1), when the compressor is running, the piston ring between the cylinder wall and the piston seal and scrape off the cylinder wall excess lubricating oil role . Therefore, it is required that the outer cylindrical surface of the piston ring be entirely close to the cylinder wall so that the compressed gas reaches the prescribed pressure. Piston ring quality is good or bad, a direct impact on compressor work,
