This standard is a revision of J72005.5-Reciprocating piston compressor metal flat packing and oil scraper ring. The original standard was shortened and modified during the revision. The main technical content has not been changed. This standard is the fifth part of the JB/T92 series of standards for metal flat packings for differential piston compressors. The series of standards includes the following parts: Part 1: (i.e. JD/T9[02.1): Metal flat packings - three-dimensional sealing rings Part 2: (B9102.2): Metal flat packings - three-dimensional oil scraper rings - one and six sealing diagrams Part 3: (i.e. JB102.3): Metal mesh flat packings Part 4: (i.e. JB/U2.4): Metal mesh flat packings - two-diameter notched scraper rings Part 5: (i.e. JB/9102.5): Tensile springs for metal semi-metal packings - sealing rings and scraper rings Part 6: (i.e. J89102.6): Metallic flat packings for sealing and scraping pools according to technical conditions
This standard replaces J72005.3-87 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Machinery. The main drafting unit of this standard is Chengyang Compressor Factory. The main drafters of this standard are Zi Fujing, Feng Quanke, and Shen Mingyao. 21
