铸铁活塞环从设计到加工完成,影响其弹力因素甚多。我厂制造活塞环的规格最大为φ820×23×12（外径×壁厚×高度）,最小为φ24×1.6×2,其压缩机的排气量为 100米3/分、40米3/分、1.5米3/分等,活塞环的最高工作压力为350个大气压。按照活塞环在气缸中的工作条件,活塞环应该具有高度的机械性能和足够稳定的弹性,同时也应具有高度的耐磨性、耐蚀性和耐热性。如果活塞环没有足够稳定的弹性,气缸与活塞就不能进行很好的密
Cast iron piston rings from design to processing is completed, affecting many factors of its elasticity. I plant the largest piston ring specifications for the specifications φ820 × 23 × 12 (diameter × wall thickness × height), the minimum φ24 × 1.6 × 2, the compressor displacement of 100 m 3 / min, 40 m 3 / Min, 1.5 m 3 / min, the maximum working pressure of the piston ring is 350 atm. In accordance with the operating conditions of the piston ring in the cylinder, the piston ring should have a high degree of mechanical properties and sufficient stability of elasticity, but also should have a high degree of wear resistance, corrosion resistance and heat resistance. If the piston ring is not stable enough elasticity, the cylinder and the piston can not be very close
